A common feature of text input tools is spell checking. It exists in search engines, email clients and of course in word processors like Microsoft Word. By having a spell checker when you are typing you can be more efficient than if you had to check the spelling with a separate proofing tool. Spell checking is a common request by the users of the room planning software CET Designer which is developed by Configura. In this thesis Windows Spell Checking API is evaluated and compared to alternative spell checkers. A prototype of an integrated spell checker in CET Designer text tool is then implemented with Windows Spell Checking API.

To decrease the rendering time of a mesh, Level of Detail can be generated by reducing the number of polygons based on some geometrical error. While this works well for most meshes, it is not suitable for meshes with an associated texture atlas. By iteratively collapsing edges based on an extended version of Quadric Error Metric taking both spatial and texture coordinates into account, textured meshes can also be simplified. Results show that constraining edge collapses in the seams of a mesh give poor geometrical appearance when it is reduced to a few polygons. By allowing seam edge collapses and by using a pull-push algorithm to fill areas located outside the seam borders of the texture atlas, the appearance of the mesh is better preserved.

This study was made at Configura Sverige AB and investigates different solutions for a generalized language resource system and a localization tool. The software application Configura CET Designer® that the solutions in this thesis should be applicable to is a kind of CAD tool that is used as a sales tool for configurable products that require space planning. Some types of products that CET Designer® is used for are kitchen, office and industrial solutions. The purpose of the thesis is to find an overall solution for the resource system that manages text resources in a more efficient way than the present custom made solution. One of the most important aspects is that translations of text resources to different human languages must be a lot more efficient than in the present solution.In the first part of this report an analysis of Configuras present custom-made resource system that is used in CET Designer® is made.The next part briefly mentions different types of solutions that exist on the market. This information is used to get a background of existing solutions that might be useful for a generalized language resource system and the range of different localization tools that exists.In the main part different solutions are compared and matched to general demands that can be applied to a lot of different applications that uses text resources. All of the solutions are also matched to the specific demands that apply to CET Designer®. Based on the matches to the demands and the analyzing discussions of possible solutions different recommendations of suitable solutions are made for applications in general as well as for CET Designer®.There are basically two different types of solutions and those are the custom-made system and the tools already available on the market. In many cases available tools offer a solution that is well designed and suits the needs well. Custom-made solutions are on the other hand very adaptable to different kinds of special requirements. The part of the management of resources where the biggest difference between those solutions is found is in the localization tool. The most advanced localization tools available on the market offers a functionality for managing localization projects which is economically indefensible to develop to the same advanced level in a custom-made tool. The advanced linguistically functions that exist in some available localization tools are the ones that make the biggest difference from a custom made tool. There exist several different tools that are available and compatible with custom-made tools which make it possible to create a well adjusted and very powerful tool.
Denna studie är genomförd på Configura Sverige AB och den undersöker olika lösningar för ett generellt resurssystem och lokaliseringsverktyg för språkliga resurser. Programvaran som lösningarna i detta arbete ska kunna appliceras på är Configura CET Designer®. Detta är en typ av CAD-verktyg vilket används för konfigurerbara produkter som kräver utrymmesplanering. Några typer av produkter som CET Designer® används för är kök, kontor och industriella lösningar. Syftet med arbetet är att finna en övergripande lösning för resurssystemet som hanterar textresurserna effektivare än den nuvarande egenutvecklade lösningen. En av de viktigaste aspekterna är att översättningar av textresurser måste vara mycket effektivare än i den nuvarande lösningen.Studien är indelad i olika delar där den första delen analyserar Configuras nuvarande resurssystem som är egentillverkat och används i CET Designer®.Nästa del som föregår huvuddelen av rapporten tar i korthet upp olika lösningar som finns på marknaden. Denna information används för att få en bakgrund kring vilka lösningar som kan vara användbara för ett generellt resurssystem för språkliga resurser och vilken vidd av olika befintliga lokaliseringsverktyg som finns.I huvuddelen av rapporten är olika lösningar jämförda och matchade mot generella krav som kan gälla för många olika applikationer som använder sig av textresurser. Alla lösningar är också matchade mot de specifika kraven som gäller för CET Designer®. Baserat på kravmatchningen och den analyserande diskussionen av möjliga lösningar är olika rekommendationer på passande lösningar gjorda. Detta både för generella programvaror likaväl som för CET Designer®.Det finns i huvudsak två olika typer av lösningar, egenutvecklade respektive befintliga verktyg som är tillgängliga på marknaden. I många fall erbjuder tillgängliga verktyg en väldesignad lösning som tillgodoser behoven på ett bra sätt. Egenutvecklade lösningar är å andra sidan väldigt anpassningsbara till olika speciella krav. En av delarna i hanteringen av resurser där skillnaden är som störst mellan dessa två typer av lösningar är lokaliseringsverktyget. De mest avancerade lokaliseringsverktygen som finns tillgängliga på marknaden har en funktionalitet för hantering av resurser vilken är ekonomiskt oförsvarbar att utveckla till samma avancerade nivå i ett egenutvecklat verktyg. De avancerade lingvistiska funktionerna som finns tillgängliga i några lokaliseringsverktyg är de som utgör den största skillnaden mot ett egenutvecklat verktyg. Det finns idag flera olika verktyg som är tillgängliga på marknaden som kan kombineras med egenutvecklade verktyg vilket gör att det är fullt möjligt att skapa ett mycket kraftfullt och välanpassat verktyg.

This thesis details the implementation of a navigation mesh within the interior space planning software CET Designer. The motivation for this is to investigate whether a navigation mesh is a suitable alternative to its current path finding solution which is based on a waypoint graph. An empirical analysis between the navigation mesh and the waypoint graph was also conducted. A navigation mesh is successfully implemented and an alternative triangulation method is also tested. The alternative method which is referred to as "narrowest first-ear clipping" seems to create a navigation mesh that produces slightly shorter paths than a navigation mesh that utilizes an arbitrary triangulation method. It is argued that the navigation mesh alleviates much work from the user since it requires less user input. The mesh is also able to generate paths between any two given points within it. This makes it much more dynamic than the waypoint graph. The conducted analysis shows that the navigation mesh seems to generate paths that are generally shorter than the waypoint graph. The path generation time for the navigation mesh is on average slower than the waypoint graph. We failed to provide an environment where the navigation mesh was faster on average than the waypoint graph. However, the time difference between the navigation mesh and the waypoint graph seemed to reduce as the test environment size increased.

A major problem during development and maintenance of software is lack of quality documentation. Many programers have problems identifying which infor- mation is relevant for someone with no knowledge of the system and therefore write incomplete documentation. One way to get around these problems would be to use a tool that extracts information from both comments and the actual source code and presents the structure of the program visually. This thesis aims to design an XML-driven system for the extraction and pre- sentation of meta information about source code to that purpose. Relevant meta information in this case is, for example, which entities (classes, methods, variables, etc.) exist in the program and how they interact with each other. The result is a prototype implemented to manage two company developed lan- guages. The prototype demonstrates how the system can be implemented and show that the approach is scalable. The prototype is not suitable for commercial use due to its abstraction level, but with the help of qualified XML databases there are great possibilities to build a usable system using the same techniques in the future.
Ett stort problem under utvecklingen och underhållet av mjukvara är bristande dokumentation av källkoden. Många programmerare har svårt att identifiera vilken information som är viktig för någon som inte är insatt i systemet och skriver därför bristfällig dokumentation. Ett sätt att komma runt dessa problem skulle vara att använda verktyg som extraherar information från såväl kommentarer som faktisk källkod och presenterar programmets struktur påett tydligt och visuellt sätt. Det här examensarbetet ämnar att designa ett system för XML-driven extra- hering och presentation av metainformation om källkoden med just det syftet. Metainformationen som avses här är exempelvis vilka entiteter (klasser, metoder, variabler, mm.) som finns i källkoden samt hur dessa interagerar med varandra. Resultatet är en prototyp implementerad för att hantera tvåföretagsutvecklade språk. Prototypen demonstrerar hur systemet kan implementeras och visar att me- toden är skalbar. Prototypen är abstraktionsmässigt inte lämplig för kommersiellt bruk men med hjälp av kvalificerade XML-databaser finns det stora möjligheter att i framtiden bygga ett praktiskt användbart system baserat på samma tekniker.

Katten är bland de vanligaste husdjuren i Sverige och att ha innekatt blir alltmer vanligt. Katten har många behov som exempelvis att få röra på sig och vässa klorna, vilket är stora aspekter i deras natur. Att aktivera katten är en viktig del i deras vardag för att undvika att de utvecklar oönskade beteenden som exempelvis att riva sin ägare. Bor man på en mindre yta kan det dock vara mer utmanande samt problematiskt att tillfredsställa detta behov tillräckligt. Mitt fokus har därmed varit att ta fram ett alternativt koncept på klösmöbel som även passar kattägare som bor mindre. På dagens marknad kräver de stora varianterna på klösmöbler ofta mycket golvyta, vilket kan bli ett problem om man bor mindre. Idag är det vanligt att kattägare bygger egna klösmöbler, men det är tidskrävande och därmed inte alltid önskvärt. Under projektets gång har jag intervjuat er kattägare och funnit ett behov av en större klösmöbel som passar in i det vardagliga hemmet och som lämpar sig om man bor mindre. En enkät skickades ut i olika kattforum där det tydligt syntes att kattägare ser ett värde om de själva kunde utnyttja klösmöbeln. Därmed designade jag en klösmöbel i kombination med en möbel som ofta nns i det vardagliga hemmet för både katten och kattägaren.
The cat is among the most popular pets in Sweden and having an indoor cat has become more common. A cat has many needs. For example, they need to be activated through play and allowed to sharpen their claws by scratching since these are major aspects in their nature. Activating your cat is an important part of their everyday life and to prevent them from obtaining unwanted behaviours, such as scratching their owner. However, satisfying the needs of a cat can become a di cult task and problematic for cat owners living more cramped home accommodations. Therefore, my focus has been to develop an alternate concept of a scratching post that also suits cat owners living in smaller homes. Larger scratching posts on today’s market often require considerable space on the oor, which can be a problem if you have a small home. It has become common for cat owners to construct their own scratching posts today, but that can be rather time consuming and thus often not desirable. During the course of my project, I have interviewed multiple cat owners and found a need for a larger scratching post that blends into the ordinary household. A survey was submitted onto various cat forums where the response clearly showed that cat owners found value in the concepts where they themselves could utilise the scratching post. Thus, I combined a scratching post with a typical type of furniture you often see in the ordinary household, one that can be used by both cat and cat owner.

Bakgrund och problem: En harmonisering inom redovisningsområdet i Sverige har skett, bland annat på grund av Sveriges inträde i EU. En av förändringarna är sättet koncerner numera redovisar goodwill. Under tidigare reglering skrevs goodwill av under en femårsperiod. I och med införandet av IAS förordningen har goodwill inte längre någon bestämd livslängd och testas istället årligen om nedskrivningsbehov föreligger. Värderingen av goodwill baseras på framtida prognoser, vilka alltid innehåller en viss osäkerhet. På grund av att goodwill inte längre har en bestämd livslängd utgör goodwillposten en allt större del av företags balansräkning. Eniro är ett av de mer extrema fallen. För räkenskapsåret 2008 redovisar Eniro totala tillgångar på 16.620 msek varav 11.374 msek är goodwill. När goodwill är en så stor del av företags totala tillgångar kan en felvärdering få ödestiga konsekvenser. Då värderingen av goodwill baseras på prognoser finns det en flexibilitet som skulle kunna nyttjas för personlig vinning. Studien undersöker om det finns ett samband mellan goodwillnedskrivningar och faktorerna företagsstorlek, rörlig ersättning till verkställande direktör samt om verkställande direktör är nytillsatt. Syfte: Syftet med studien är att studera om olika incitament påverkar företag att utnyttja flexibiliteten i redovisningen av goodwill. Metod: För att uppfylla syftet med studien har en kvantitativ metod tillämpats. Företag noterade på Stockholm Nasdaq OMX Large Cap och Mid Cap har behandlats. Datan om företagen har samlats in från företagens årsredovisningar räkenskapsåren 2005-2008. Resultat och slutsatser: Studien visar att nytillsatta verkställande direktörer oftare skriver ner goodwill än ej nytillsatta verkställande direktörer. Nytillsatta verkställande direktörer skriver dock ner goodwill med en lägre summa än ej nytillsatta verkställande direktörer. Resultatet förklaras med den höga variansen för nedskrivningarna gjorda av ej nytillsatta verkställande direktörer. Studien finner att stora företag oftare skriver ner goodwill och att nedskrivningarna är av ett högre värde än mindre företag. Ett resultat som finner stöd av tidigare forskning. Studien visar även att det finns incitament för verkställande direktörer under nästan samtliga räkenskapsår i studiens urval.

Over recent years the structural ceramics industry in Brazil has found a very favorable market for growth. However, difficulties related to productivity and product quality are partially inhibiting this possible growth. An alternative for trying to solve these problems and, thus, provide the pottery industry the feasibility of full development, is the substitution of firewood used in the burning process by natural gas. In order to contribute to this process of technological innovation, this paper studies the effect of co-use of ceramic phyllite and kaolin waste on the properties of a clay matrix, verifying the possible benefits that these raw materials can give to the final product, as well as the possibility of such materials to reduce the heat load necessary to obtain products with equal or superior quality. The study was divided into two steps: characterization of materials and study of formulations. Two clays, a phyllite and a residue of kaolin were characterized by the following techniques: laser granulometry, plasticity index by Atterberg limits, X-ray fluorescence, X-ray diffraction, mineralogical composition by Rietveld, thermogravimetric and differential thermal analysis. To study the formulations, specifically for evaluation of technological properties of the parts, was performed an experimental model that combined planning involving a mixture of three components (standard mass x phyllite x kaolin waste) and a 23 factorial design with central point associated with thermal processing parameters. The experiment was performed with restricted strip-plot randomization. In total, 13 compositional points were investigated within the following constraints: phyllite ≤ 20% by weight, kaolin waste ≤ 40% by weight, and standard mass ≥ 60% by weight. The thermal parameters were used at the following levels: 750 and 950 ?C to the firing temperature, 5 and 15 ?C/min at the heating rate, 15 and 45min to the baseline. The results showed that the introduction of phyllite and/or kaolin waste in ceramic body produced a number of benefits in properties of the final product, such as: decreased absorption of water, apparent porosity and linear retraction at burn; besides the increase in apparent specific mass and mechanical properties of parts. The best results were obtained in the compositional points where the sum of the levels of kaolin waste and phyllite was maximal (40% by weight), as well as conditions which were used in firing temperatures of 950 ?C. Regarding the prospect of savings in heat energy required to form the desired microstructure, the phyllite and the residue of kaolin, for having small particle sizes and constitutions mineralogical phases with the presence of fluxes, contributed to the optimization of the firing cycle.
Ao longo dos ?ltimos anos a ind?stria de cer?mica estrutural no Brasil vem encontrando um mercado bastante favor?vel para o crescimento. Entretanto dificuldades relacionadas ? produtividade e qualidade dos produtos est?o inibindo parcialmente esse poss?vel crescimento. Uma das alternativas para tentar solucionar esses problemas e, consequentemente, proporcionar ao setor oleiro a viabilidade do pleno desenvolvimento, ? a substitui??o da lenha utilizada no processo de queima pelo g?s natural. Com o intuito de contribuir nesse processo de inova??o tecnol?gica, o presente trabalho trata-se de um estudo do efeito da co-utiliza??o de filito cer?mico e res?duo de caulim sobre as propriedades de uma matriz argilosa, verificando os poss?veis benef?cios que esses materiais podem atribuir ao produto final, bem como, a possibilidade dessas mat?rias-primas reduzirem a carga t?rmica necess?ria para obten??o de produtos de igual ou superior qualidade. O trabalho foi divido em duas etapas: caracteriza??o dos materiais e estudo das formula??es. Duas argilas, um filito e um res?duo de caulim foram caracterizados atrav?s das seguintes t?cnicas: granulometria ? laser, ?ndice de plasticidade pelos limites Atterberg, fluoresc?ncia de raios X, difra??o de raios X, composi??o mineral?gica por Rietveld, an?lise termogravim?trica e an?lise t?rmica diferencial. Para o estudo das formula??es, mais especificamente para avalia??o das propriedades tecnol?gicas das pe?as, foi executado um modelo experimental que combinou um planejamento envolvendo mistura de tr?s componentes (massa padr?o x filito x res?duo de caulim) e um planejamento fatorial 23 com ponto central associado aos par?metros t?rmicos de processamento. A experimenta??o foi realizada com restri??o na aleatoriza??o por strip-plot. No total foram investigados 13 pontos composicionais dentro das seguintes restri??es: filito ≤ 20% em peso; res?duo de caulim ≤ 40% em peso; e massa padr?o ≥ 60% em peso. Os par?metros t?rmicos foram utilizados nos seguintes n?veis: 750 e 950 ?C para temperatura de queima; 5 e 15 ?C/min para a taxa de aquecimento; 15 e 45 min para o patamar. Os resultados obtidos demostraram que a introdu??o do filito e/ou res?duo de caulim na massa cer?mica produz uma s?rie de benef?cios nas propriedades do produto final, tais como: redu??o na absor??o de ?gua, porosidade aparente e retra??o linear de queima; al?m do aumento na massa espec?fica aparente e na resist?ncia mec?nica das pe?as. Os melhores resultados foram obtidos nos pontos composicionais em que a soma dos teores de filito e res?duo de caulim foi m?xima (40 % em peso), assim como, nas condi??es de queima em que foram utilizadas temperaturas de 950 ?C. Em rela??o ? perspectiva de economia na energia t?rmica necess?ria para forma??o da microestrutura desej?vel, o filito e o res?duo de caulim por apresentarem pequenos tamanhos de part?culas e constitui??es mineral?gicas com presen?a de fases fundentes, contribu?ram para a otimiza??o do ciclo de queima.

Cette thèse est focalisée sur la conception et la réalisation d'un filtre CEM hybride intégré pour une application aéronautique. Les travaux effectués durant cette thèse sont réalisés dans le cadre d'un projet FRAE (Fondation de Recherche pour l'Aéronautique et l'Espace) intitulé FEMINA (Filtrage Electromagnétiques et Matériaux pour l'INtégration en Aéronautique). Afin de protéger le réseau de bord des perturbations électromagnétiques conduites et rayonnées et répondre aux normes concernant la compatibilité électromagnétique (CEM) et plus particulièrement la norme aéronautique "DO160F [150KHz, 30MHz]", un filtre CEM est absolument nécessaire pour les cartes d'alimentations des dispositifs électroniques d'un avion. Les niveaux des perturbations générées par ce type d'équipement exigent une conception soignée pour assurer le filtrage des courants parasites qui se propagent en mode commun (MC) et en mode différentiel (MD). C'est pourquoi, la première partie du travail réalisé est consacrée à la modélisation électromagnétique de la carte d'alimentation utilisée comme support à cette étude. Cette modélisation est basée sur une représentation de type "boîte noire". Le modèle identifié est composé de sources de perturbations et d'impédances de MC et de MD équivalentes. Cette première étape permet de définir la structure électrique du filtre et les valeurs des composants à mettre en œuvre. Pour atteindre les performances requises, nous proposons dans ce travail un filtre CEM hybride optimisé, hybride signifiant qu'il est réalisé par association d'une partie purement passive et d'un filtre actif. Cette association permet de tirer le meilleur parti de chaque technologie de filtrage. Le filtre actif permet de traiter les perturbations à basses fréquences et la partie passive est dimensionnée pour les perturbations à hautes fréquences. Une intégration complète dans le circuit imprimé (PCB) des parties passives, capacitives et inductives, est proposée dans la deuxième partie de ce travail. Après avoir choisi les matériaux magnétique et diélectrique qui répondent au mieux au cahier de charge défini dans la première partie, plusieurs tests d'intégration dans le PCB ont été effectués. En prenant en compte la fragilité des matériaux magnétiques (ferrites), une géométrie plane qui répond aux spécifications a été proposée. Les principaux avantages de l'intégration proposée sont la réduction des effets inductifs et capacitifs parasites conduisant, de fait, à une augmentation des atténuations à hautes fréquences et l'augmentation de la compacité du filtre CEM. Nous démontrons que le filtre passif intégré réalisé réduit les interférences en MC et en MD dans la gamme de fréquences qui s'étend de 2,5MHz à 30MHz. Afin de compenser les tensions perturbatrices de mode différentiel jusqu'à 2,5MHz, une nouvelle topologie de filtre actif est proposée. Dans cette structure, l'injection des tensions de compensation des perturbations est effectuée à l'aide d'un enroulement auxiliaire ajouté aux enroulements couplés du filtre passif intégré. Les composants du filtre actif sont montés sur la face supérieure du PCB (composants CMS) dans lequel le filtre passif est intégré. L'assemblage du filtre hybride intégré (4 x 5 x 0,4 cm3) réduit les perturbations en MC et en MD dans la gamme de fréquence [150 kHz, 30 MHz]. Grâce à l'intégration et à l'optimisation de la topologie du filtre actif, le volume du filtre hybride est 75% plus faible que celui de l'ancien filtre CEM utilisé à l'entrée du convertisseur (4 x 5 x 1,6 cm3) tout en conservant un rendement élevé.

Nos travaux portent sur l’étude d’une méthodologie de modélisation prédictive CEM en émission conduite pour une chaîne d’actionnement (CA). L’objectif ultime, lié à l’utilisation de ces modèles pour le dimensionnement de ce système, est basé sur une optimisation sous contraintes (conception sous contraintes). Au delà de l’application, nous cherchons à mettre en exergue les bénéfices d’une modélisation multi-niveaux dans la recherche d’un compromis entre la précision et la durée de simulation de ces modèles. Dès lors, le but sera d’obtenir un modèle prédictif pour les perturbations électromagnétiques (PEM) d’émission conduite provenant de la CA étudiée et de confronter les résultats de simulations aux résultats expérimentaux. Pour ce faire, le développement d’un premier modèle représentatif des différents phénomènes physiques intervenant dans le système est nécessaire de façon à simuler ces PEM. Dans le but d’améliorer la précision et la durée de simulation de ce premier modèle, nous nous sommes intéressés à l’application d’un algorithme de macromodélisation passive permettant d’obtenir un macromodèle précis et rapide à évaluer, ce qui permet d’en faire un prétendant idoine en vue d’une optimisation. Ensuite, dans le cadre d’une optimisation sous contraintes, nous avons proposé une illustration de l’utilisation du modèle CEM établi pour la CA étudiée. Cette optimisation par évolution différentielle se limitera au dimensionnement d’un filtre CEM, en faisant intervenir, à cette occasion, des contraintes reflétant la réduction des sources d’échauffement
This phD dissertation is focused on the study of a methodology in order to predict the conducted electromagnetic interferences (EMI) arising from an actuating system (AS). The ultimate objective, linked to the use of these models for the sizing of this system, is based on an optimization under constraints (design under constraints).Beyond the application, we try to highlight the profits of multilevel modeling in looking for a tradeoff between the accuracy and the time cost of these models. Thereupon, the purpose will be to get a predictive model for the AS conducted EMI and to compare the simulation results to measurements.To that end, the development of a first representative model of the various physical phenomena occurring in the system is necessary so as to simulate the conducted EMI. In the purpose to improve the accuracy and the time cost of this first model, we were interested with care to a passive macromodeling algorithm allowing to obtain a fast and accurate macromodel to be estimated, what allows to make it an ideal pretender with the aim of an optimization.Then, within the framework of an optimization under constraints, we proposed an illustration of the use of the EMC model established for the studied AS. This optimization based on differential evolution will limit itself to the sizing of an EMI filter, by bringing in, on this occasion, constraints which reflect, in our case, thermal losses

Synthetic inorganic pigments are the most widely used in ceramic applications because they have excellent chemical and thermal stability and also, in general, a lower toxicity to man and to the environment. In the present work, the ceramic black pigment CoFe2O4 was synthesized by the polymerization Complex method (MPC) in order to form a material with good chemical homogeneity. Aiming to optimize the process of getting the pigment through the MPC was used a fractional factorial design 2(5-2), with resolution III. The factors studied in mathematical models were: citric acid concentration, the pyrolysis time, temperature, time and rate of calcination. The response surfaces using the software statistica 7.0. The powders were characterized by thermal analysis (TG/DSC), x-ray diffraction (XRD), scanning electron microscopy (SEM) and spectroscopy in the UV-visible. Based on the results, there was the formation of phase cobalt ferrite (CoFe2O4) with spinel structure. The color of the pigments obtained showed dark shades, from black to gray. The model chosen was appropriate since proved to be adjusted and predictive. Planning also showed that all factors were significant, with a confidence level of 95%

Cette thèse cherche à comprendre et à analyser les fondements historiques, sociaux, culturels et genrés d’une méconnaissance et d’une sous-valorisation actuelles des costumiers et des costumières, en accordant un primat à leur parole propre. Traitant des origines théoriques de l’art costumier à partir de l’apparition de l’appellation professionnelle consacrée, la première partie retrace le parcours et les luttes multiples de Pierre-Nicolas Sarrazin, en cherchant à identifier les motifs de l’échec de la valorisation professionnelle entreprise par ce dernier au XVIIIe siècle. La deuxième partie présente, à partir de l’analyse d’un recueil d’entretiens de costumiers d’aujourd’hui, les notions de métiers de service et de rapport de commande, de genre et de « souci de l’autre » comme étant les caractéristiques de cette activité professionnelle, et autant de leviers potentiels d’oppression. Enfin, la troisième partie étudie la carrière de Dominique Fabrègue – spécialiste de la coupe en un morceau – en tant que « fabrique » d’une œuvre dont la portée est esthétique et critique, de manière à défendre l’idée que l’art costumier constitue un art à part entière, qui pour être second dans l’élaboration d’un spectacle, n’est pas pour autant secondaire
This work aims at analyzing the historical, social, cultural and gender factors responsible for the current undermining of the costume designers and makers profession. The first part consists in a historical research onthe theoretical origins of the Art of Costume starting with the appearance of the professional vocable - Costumier - invented by Pierre-Nicolas Sarrazin, as well as a study of the means this latter used to promote his field of work during the 18th century and how he came to fail. The second part is an interview-collection (2013 to 2016) - based reflection on the order nature of the work, the gender characterization of the workers and « care » as a creative motivation. It demonstrates how these specifics are potential ways to oppress the costume designers and makers and to deny them the appreciation and salary they deserve. The third part is an a esthetic critique of Costume Designer Dominique Fabrègue’s career, and the « Cut in one piece » Artwork she specialized in. This section argues that the discipline of designing costumes is an Art in full, and as it may come second in the process of putting on a play, is not for all that secondary and shouldn’t be considered assuch

Rio Grande do Norte State stands out as one great producer of structural clay of the brazilian northeastern. The Valley Assu ceramic tiles production stands out obtained from ilitics ball clays that abound in the region under study. Ceramics formulation and the design of experiments with mixture approach, has been applied for researchers, come as an important aid to decrease the number of experiments necessary to the optimization. In this context, the objective of this work is to evaluate the effects of the formulation, temperature and heating rate in the physical-mechanical properties of the red ceramic body used for roofing tile fabrication of the Valley Assu, using design of mixture experiments. Four clays samples used in two ceramics industry of the region were use as raw material and characterized by X-ray diffraction, chemical composition, differential thermal analysis (DTA), thermogravimetric analysis (TGA), particle size distribution analysis and plasticity techniques. Afterwards, they were defined initial molded bodies and made specimens were then prepared by uniaxial pressing at 25 MPa before firing at 850, 950 and 1050 ?C in a laboratory furnace, with heating rate in the proportions of 5, 10 e 15 ?C/min. The following tecnologicals properties were evaluated: linear firing shrinkage, water absorption and flexural strength. Results show that the temperature 1050 ?C and heating rate of 5 ?C/min was the best condition, therefore presented significance in all physical-mechanical properties. The model was accepted as valid based of the production of three new formulations with fractions mass diferents of the initial molded bodies and heated with temperature at 1050 ?C and heating rate of 5 ?C/min. Considering the formulation, temperature and heating rate as variables of the equations, another model was suggested, where from the aplication of design of experiments with mixtures was possible to get a best formulation, whose experimental error is the minor in relation to the too much formulations

A regi?o do Vale do Assu destaca-se na produ??o de telhas cer?micas, cuja principal constitui??o s?o argilas pl?sticas il?ticas, abundantes na regi?o. O estudo das formula??es de massas cer?micas, juntamente com o aux?lio do planejamento experimental para misturas, tem sido utilizado por pesquisadores, visando a diminui??o do n?mero de experimentos necess?rios para a otimiza??o de formula??es. Neste contexto, este trabalho tem por objetivo estudar o efeito das formula??es, temperatura e taxa de queima nas propriedades f?sico-mec?nicas das massas cer?micas para fabrica??o de telhas da regi?o do Vale do Assu, utilizando planejamento de experimentos para misturas. Quatro argilas usadas em duas ind?strias cer?micas da regi?o foram utilizadas como mat?ria-prima e submetidas a ensaios de difra??o de raio X, composi??o qu?mica, TG/DTA, distribui??o de tamanho de part?cula e plasticidade. Foram definidas formula??es iniciais e confeccionados corpos-de-prova por prensagem uniaxial e de simples efeito a 25 MPa e queimados a 850, 950 e 1050 ?C, com taxas de aquecimento de 5, 10 e 15 ?C/min. As propriedades tecnol?gicas de queima avaliadas foram retra??o linear, absor??o de ?gua e resist?ncia ? flex?o (tr?s pontos). Resultados mostram que a temperatura 1050 ?C e taxa de aquecimento de 5 ?C/min foi a melhor condi??o de queima, pois apresentou efeito de signific?ncia em todas as propriedades f?sico-mec?ncias. O modelo foi validado a partir da produ??o de tr?s novas formula??es com fra??es m?ssicas diferentes das formula??es iniciais e queimadas com temperatura a 1050 ?C e taxa de queima de 5 ?C/min. Considerando as formula??es, temperaturas e taxas de aquecimento como vari?veis das equa??es, outro modelo foi sugerido, onde a partir da aplica??o do planejamento de experimentos para misturas foi poss?vel obter uma formula??o ?tima, cujo erro experimental ? o menor em rela??o ?s demais formula??es

Le contexte dans lequel vivent les organisations évolue. Elles doivent faire face à quatre nouveaux enjeux principaux : l'appartenance à des pôles et réseaux, le centrage sur les connaissances et l'innovation, la responsabilité sociétale et l'intégration de nouveaux comportements au travail. Ces nouveaux enjeux font apparaître de nouvelles parties prenantes des organisations (pouvoirs publics, société, associations, communauté scientifique, entreprises partenaires...) et diversifient leurs attentes (création d'emplois, création de connaissances, protection de l'environnement...). Ainsi, les critères d'évaluation de la performance de ces organisations se multiplient et se diversifient. Les modes de conception et de pilotage existants doivent être adaptés. Ce travail met en œuvre une recherche-action au sein de la plateforme d'imagerie préclinique MIRCen (Molecular Imaging Research Centre) du CEA, appartenant au pôle de compétitivité Medicen Paris Region ainsi qu'à divers réseaux nationaux et internationaux. Il repose sur une démarche valeurs, une approche processus et une vision systémique. Il met en évidence la nécessité de repenser la performance des organisations faisant face à ce nouveau contexte, à travers leur création de valeurs au pluriel (scientifiques, économiques, sociétales, éthiques, environnementales...), de façon à prendre en compte les aspects multi parties prenantes et multicritère. Il propose une démarche intégratrice originale permettant de modéliser cette création de valeurs et d'adopter de nouveaux modes de conception des processus et de pilotage par les valeurs adaptés à ces organisations. Il aboutit à la mise en place d'un outil opérationnel d'aide au pilotage par les valeurs qui intègre ces propositions et qui permet de répondre de façon dynamique à un ensemble d'attentes de parties prenantes, en passant par l'implication de tous les acteurs de l'organisation dans son pilotage.

Usually the inoculum used during the beginning of the harvest of ethanol production is constituted by the combination of two or more yeasts strains and in the end the most adapted one will predominate, either inoculated yeast or indigenous wild yeast. The proportion used in these industries are established empirically, of which little is known about the kinetic parameters and the influence that each yeast has on the production of ethanol and on the other metabolites. An experimental design from the blending design with Saccharomyces cerevisiae ATCC7754, S. cerevisiae CAT-1, S. cerevisiae PEDRA-2, S. cerevisiae MONASTRELL strains was proposed to understand how the interaction among the different blends occurs comparing with the ethanol, biomass, acetic acid, glycerol and biomass consumption. This study showed that the inherent characteristics to each yeast can influence the behavior of the kinetics parameters of the culture with two yeasts. It was verified that the combination among three yeasts presented similar metabolic behavior. From the blending design it was possible to elaborate mathematical models that predicts the ethanol, biomass, glycerol, acetic acid and residual sucrose amount in all four yeasts mixtures. It was also possible to identify that the mixture of CAT-1 and PEDRA-2 presented higher ethanol production when cultivated in a 1: 1 ratio, and also in the cultivation with the two yeasts (CAT-1 and PEDRA-2) to CAT-1 was higher in yeast. This research also presents the synthetic cane juice composition and the detail of growth kinetics, substrates consume and production of MONASTRELL yeast products that had not been studied until now.
Normalmente o inóculo utilizado durante o início da safra da produção de etanol é constituído da combinação de duas ou mais linhagem de leveduras e no final prevalece aquela que mais se adaptar, seja as leveduras inoculadas ou leveduras selvagens autóctones. Quanto as proporções utilizadas nas industrias essas são estabelecidas de forma empírica, dos quais sabe-se pouco sobre os parâmetros cinéticos e a influência que cada levedura acarreta sobre a produção do etanol e sobre os outros metabólitos. Um planejamento experimental a partir do delineamento de mistura com as cepas de Saccharomycescerevisiae ATCC7754, S. cerevisiae CAT-1, S. cerevisiae PEDRA-2, S. cerevisiae MONASTRELL foi proposto para entender como ocorre a interação entre as diferentes misturas comparando com os cultivos puros diante das respostas etanol, biomassa, ácido acético, glicerol e consumo de biomassa. Neste estudo mostrou que as características inerentes a cada levedura podem influenciar no comportamento dos parâmetros cinéticos do cultivo com duas leveduras. Verificou-se que a maioria das combinações entre três leveduras apresentam comportamento metabólico semelhante. A partir do delineamento de mistura pôde elaborar modelos matemáticos que predizem a quantidade de etanol, biomassa, glicerol, ácido acético e sacarose residual nas misturas das quatro leveduras. Conseguiu-se também identificar que o ensaio com a mistura de CAT-1 e PEDRA-2 apresentou maior produção de etanol na proporções de 1:1 da concentração de inóculo, e ainda neste cultivo a CAT-1 se sobressaiu em quantidade de leveduras. Esta pesquisa ainda apresenta a composição de caldo de cana-de-açúcar sintético e o detalhamento da cinética de crescimento, consumo de substrato e produção de produtos da levedura MONASTRELL que até então não tinham sido estudada.

Um método cromatográfico eletrocinético micelar para a determinação simultânea do mesilato de nelfinavir e das impurezas ácido 3-hidroxi-2-metilbenzóico e benzoato de (2R,3R)-4-((3S,4aS,8aS)-3-(terc-butilcarbamoil)octahidroisoquinolina-2(1H)-il)-3-hidroxi-1-(feniltio)butano-2-amônio, com tempo de análise de 25 minutos, foi proposto. O eletrólito composto por tampão tetraborato de sódio (pH 9,24; 25 mmol L−1), dodecil sulfato de sódio (9 mmol L−1) e metanol (10%, v/v) foi otimizado utilizando planejamento fatorial misto, com detecção direta em 200 nm. Após avaliação das figuras de mérito seletividade, linearidade, precisão, limite de detecção, limite de quantificação, exatidão e robustez (Teste de Youden), o método foi aplicado na análise do mesilato de nelfinavir e suas impurezas em uma formulação farmacêutica (comprimidos). O método otimizado pode ser útil na determinação desses analitos em processos de monitoramento de síntese, matérias-primas e formulações farmacêuticas, oferecendo como vantagens baixo consumo de solventes, pequena demanda de amostra e uso de colunas não específicas.
A methodology for the simultaneous determination of nelfinavir mesylate and the impurities 3-hydroxy-2-methylbenzoic acid and (2R,3R)-4-((3S,4aS,8aS)-3-(tert-butylcarbamoyl) octahydroisoquinolin-2(1H)-yl)-3-hydroxy-1-(phenylthio)butan-2-aminium benzoate by micellar electrokinetic chromatography, with an analysis time of 25 min, was proposed. An electrolyte composed of sodium tetraborate buffer (pH 9.24; 25 mmol L−1), sodium dodecyl sulphate (9 mmol L−1) and methanol (10%, v/v) was optimized using a mixed-level factorial design, with direct detection at 200 nm. After evaluating some figures of merit, such as selectivity, linearity, precision, limit of detection, limit of quantification, accuracy and robustness (Youden’s test), the method was successfully applied to the analysis of nelfinavir mesylate and its impurities in a pharmaceutical formulation (tablets). The optimized methodology is demonstrated to be useful in the determination of these analytes in a synthesis monitoring process, in raw materials and in pharmaceutical formulations, while offering low solvent consumption, requiring a small sample and using non-specific columns as advantages.

I studien kontrollerades för en minskning av nedstämdhet kunde tillskrivas en ökad fysisk aktivitetsnivå. En single case experimental design användes för ändamålet, med dagliga skattningar av sömn, nedstämdhet och fysisk aktivitetsnivå. Symtom på såväl insomi som nedstämdhet minskade signifikant hos tre av sex deltagare. Minskad nedstämdhet kunde inte förklaras av ökad fysisk aktivitetsnivå. Samvariation observerades mellan depression och insomni. Resultaten visar att insomni och depression kan påverkas av samma behandling, vilket antyder förekomst av gemensamma vidmakthållande mekanismer.
Insomnia and depression are two common mental health problems. This study investigated whether a proven effective treatment for insomnia CBT-I, would change the severity of depressive symptoms, for participants with comorbid insomnia and depression. It was controlled for, whether a reduction in depressive symptoms could be the result of increased physical activity. A single case experimental design, including daily measurements of sleep, depression and physical activity, was used as a means to answer the research questions. Symptoms of both depression and insomnia were significantly reduced for three out of six participants. Increased physical activity was not able to explain the decrease in depression scores. A correlation was observed, between depression and insomnia. The results shows that insomnia and depression can be affected by the same treatment, which implies existence of common perpetual mechanisms.

Description Logics (DLs) belong to a successful family of knowledge representation formalisms with two key assets: formally well-defined semantics which allows to represent knowledge in an unambiguous way and automated reasoning which allows to infer implicit knowledge from the one given explicitly. This thesis investigates various reasoning techniques for tractable DLs in the EL family which have been implemented in the CEL system. It suggests that the use of the lightweight DLs, in which reasoning is tractable, is beneficial for ontology design and maintenance both in terms of expressivity and scalability. The claim is supported by a case study on the renown medical ontology SNOMED CT and extensive empirical evaluation on several large-scale biomedical ontologies.

This study examines whether woven metal mesh is an appropriate option for usage in beds and what material the mesh should consist of to best be suited for the purpose. The woven steel mesh’s construction was based on a reference model that consists of cross-linked rods and wires. Since the aim of the project was to reach a conclusion of the mesh’s usability in beds, different parameters were examined and taken into consideration. These parameters were the durability of the mesh when carrying human weight, acoustic properties to minimize chatter when lying on the mesh and rolling properties. The durability was examined using COMSOL multiphysics. Acoustics were studied through a literature review and rolling properties were calculated using measurements on the reference model. A material investigation was done in the database software CES EduPack. It was found that steel, stainless steel and aluminum fulfilled the requirements set on durability. Stainless steel was considered too expensive and steel too heavy. Using aluminum halves the weight of the mesh in comparison to steel but doubles the price, in this case however the weight was considered to be a parameter of greater importance overriding price.

En France, une politique en matière de préservation de l’environnement et du vivant émerge au cours des années 1970 (ministère de l’environnement, lois). Depuis 2004, date à laquelle il est adoptée la stratégie nationale pour la biodiversité, et où commence à s’incarner opérationnellement, en ville, par les agendas 21, les enjeux du développement durable, cette politique n’a fait que se renforcer. Cela est notamment dû aux effets des nouvelles lois (Grenelle 1 et 2 ; Loi n° 2016-1087 du 8 août 2016 pour la reconquête de la biodiversité, de la nature et des paysages, etc.), mais aussi des travaux de l’écologie scientifique (programme trame verte urbaine) et d’une prise de conscience écologique généralisée. Dans un contexte très urbanisé avec une part croissante de la population vivant en ville, le milieu urbain, parce qu’il recèle une multitude d’espaces à caractère de nature, aux natures bien différentes, est devenu un thème de recherche privilégié. Parmi les professions concourant à améliorer le cadre de vie urbain, les paysagistes-concepteurs, par leurs missions les invitant généralement à mobiliser du matériau végétal, sont des acteurs théoriquement en capacité de traduire, par le projet, des injonctions écologiques et/ou environnementales (biodiversité, gestion des eaux, etc.). Les parcs urbains en général et plus particulièrement ceux de Marseille constituent alors un objet d’étude intéressant pour s’interroger aux modalités d’écologisation des pratiques paysagistes, et cela depuis qu’une politique environnementale a émergé (années 1970).Cette thèse s’appuie sur une triple analyse fondée à la fois sur des discours de paysagistes français, puis de gestionnaires des services des espaces verts, et enfin sur des relevés de structures végétales dans 5 parcs publics marseillais. En définitive, il apparaît, qu’outre Gilles Clément – figure paysagiste marquante – dont les fondements naturalistes sont connus mais nécessitent d’être discutés, l’écologisation de la pratique de ces professionnels reste timide et intègre encore trop peu le fonctionnement de ces écosystèmes urbains. Si cet aspect tend à changer depuis moins d’une dizaine d’années, il n’en revient pas moins que ce sont davantage les gestionnaires des services des espaces verts, pour partie inscrits dans une gestion écologique (part de la gestion différenciée) de leurs parcs et jardins, qui participent à faire évoluer les structures végétales tant dans leur composition que dans leur physionomie. Mais, force est de constater qu’il manque aujourd’hui l’expression d’un paysagisme capable d’intégrer, au-delà de l’échelle du parc, ces mêmes enjeux, relevant autant de l’urbanisme que de l’écologie. Aussi, l’écologisation de cette profession semble manquer des outils et des méthodes relevant de ces deux disciplines
In France, a policy regarding the preservation of the environment and nature emerged during the 1970s (ministry of the environment, legislation). Since 2004, when the national strategy for biodiversity was adopted, and when the priorities of sustainable development began to take shape operationally in the cities on the basis of Agenda 21, this policy has continued to gain strength. This has been in particular due to the impact of new legislation (Grenelle 1 and 2 ; Loi n° 2016-1087 of 8th August 2016 for the recovery of biodiversity, nature and landscapes, etc.), but also to scientific research in ecology (green infrastructure programme : Trame Verte Urbaine) and a widespread raising of awareness with regard to ecology. In a highly urbanised context, with more and more of the population living in cities, the urban environment, harbouring as it does a plethora of natural spaces with natural characteristics, and of a quite distinctive character, has become a favoured focus of study. Among the professions contributing to the enhancement of the urban living environment, the landscape designers, because their role generally calls for the deployment of plant material, are actors who are in theory in a position to give expression by means of their project to ecological and / or environmental imperatives (biodiversity, water management, etc.). The urban parks in general, and in particular those of Marseille, thus constitute an interesting topic of study to investigate ways of ecologization of landscape design practices, and have done since an environmental design policy began to emerge (1970s).This thesis is based on a threefold analysis focused on the discourse of French landscape designers, then of managers of green spaces departments, and finally inventories of the plant assemblages in 5 Marseille public parks. Finally, it would appear that apart from Gilles Clément – a key figure in landscape design – whose naturalist background is well known but requires discussion, the ecologization in the practices of members of this profession remains discreet, and does not sufficiently integrate the functioning of these urban ecosystems. If this aspect has tended to change over at least the past ten years, the fact remains that it is rather the managers of municipals green spaces departments, in some cases committed to the ecological management (part of gestion différenciée) of their parks and gardens, who play a role in driving change with regard to the plant assemblages in terms of both their composition and their appearance. But it is apparent that we are lacking today the expression of a landscape design approach that is capable of integrating, beyond the scale of a park, these same priorities, related as much to urban planning as to ecology. Thus the ecologization of the landscape design profession would appear to lack tools and methods derived from these two disciplines

Description Logics (DLs) belong to a successful family of knowledge representation formalisms with two key assets: formally well-defined semantics which allows to represent knowledge in an unambiguous way and automated reasoning which allows to infer implicit knowledge from the one given explicitly. This thesis investigates various reasoning techniques for tractable DLs in the EL family which have been implemented in the CEL system. It suggests that the use of the lightweight DLs, in which reasoning is tractable, is beneficial for ontology design and maintenance both in terms of expressivity and scalability. The claim is supported by a case study on the renown medical ontology SNOMED CT and extensive empirical evaluation on several large-scale biomedical ontologies.

Réalisée dans le cadre d’un contrat CIFRE, cette thèse étudie la construction, l’appropriation et les effets de la politique d’égalité professionnelle entre les femmes et les hommes chez Orange. Mobilisant la perspective appropriative des dispositifs de gestion enrichie par le concept de logiques institutionnelles, ce travail repose sur un matériau riche et varié : entretiens, données RH, séquences d’observation, documents internes, notamment. Nous montrons que la coexistence de plusieurs conceptions de l’égalité professionnelle au sein de l’entreprise structure fortement l’application de la politique au niveau local, mais également sa construction, qu’il s’agisse de l’accord d’entreprise ou de la politique non négociée. L’analyse conjointe de l’application de la politique et de ses effets, permise par la combinaison de matériaux et de méthodes qualitatifs et quantitatifs, nous donne de plus l’opportunité de comprendre les effets quantifiables (ou l’absence d’effets quantifiables) d’une mesure à l’aune de la manière dont elle est appliquée au niveau local. Nous mettons enfin en exergue les spécificités de la négociation sur l’égalité professionnelle par rapport à d’autres négociations, dues notamment à la transversalité de l’égalité professionnelle à de nombreux processus RH ; et nous soulignons l’importance de la coexistence et de l’articulation de l’accord d’entreprise et de la politique non négociée sur l’égalité professionnelle
This thesis, written while working under a CIFRE contract, studies the construction, the implementation and the effects of the gender equality policy at Orange. Using the appropriative perspective of management tools enriched by the concept of institutional logics, this work is based on various data, in particular: interviews, HR data, observations, internal documents. We show that the coexistence of various conceptions of gender equality within the company strongly affects the implementation of the gender equality policy within the entities, but also its construction, for both the collective bargaining agreement and the non-negotiated policy. The joint analysis of the implementation and of the effects of the policy, made possible by a mixed-method design, allows us to understand the quantifiable effects (or the absence of quantifiable effects) of a measure according to the way it is implemented within the entities. We underline the specificities of the collective bargaining about gender equality, notably due to the fact that gender equality cuts across various HR processes. Finally, we show the importance of the coexistence and articulation of the collective bargaining agreement and non-negotiated gender equality policy

Jessica Langley's work examines animals and nature through various media and form, including watercolor and oil painting, digitally manipulated photography, both large and small scale drawing, and various combinations of each. The work has explored narrative and emotional aspects to more mystical and ecological interpretations. The current body of work settles into banal and familiar interactions with animals, or more specifically the house cat and its accoutrements. Each element of the body of work engages specific concepts that developed out of the American landscape tradition and assimilates the banal subjects into a formal framework. The subjects are monumentalized and romanticized in order to question, not the importance of the objects, but the relevance of the sublime.

Translation Environment Tools (TEnTs) became popular in the early 1990s as a partial solution for coping with ever-increasing translation demands and the decreasing number of translators available. TEnTs allow the creation of repositories of legacy translations (translation memories) and terminology (integrated termbases) used to identify repetition in new source texts and provide alternate translations, thereby reducing the need to translate the same information twice. While awareness of the important role of terminology in translation and documentation management has been on the rise, little research is available on best practices for building and using integrated termbases. The present research is a first step toward filling this gap and provides a set of guidelines on how best to optimize the design and use of integrated termbases. Based on existing translation technology and terminology management literature, as well as our own experience, we propose that traditional terminology and terminography principles designed for stand-alone termbases should be adapted when an integrated termbase is created in order to take into account its unique characteristics: active term recognition, d one-click insertion of equivalents into the target text and document pretranslation. The proposed modifications to traditional principles cover a wide range of issues, including using record structures with fewer fields, adopting the TBX-Basic’s record structure, classifying records by project or client, creating records based on equivalent pairs rather concepts in cases where synonyms exist, recording non-term units and multiple forms of a unit, and using translated documents as sources. The overarching hypothesis and its associated concrete strategies were evaluated first against a survey of current practices in terminology management within TEnTs and later through a second survey that tested user acceptance of the strategies. The result is a set of guidelines that describe best practices relating to design, content selection and information recording within integrated termbases that will be used for translation purposes. These guidelines will serve as a point of reference for new users of TEnTs, as an academic resource for translation technology educators, as a map of challenges in terminology management within TEnTs that translation software developers seek to resolve and, finally, as a springboard for further research on the optimization of integrated termbases for translation.

Le marché actuel des systèmes électroniques est très compétitif. D’un point de vue de la CEM, ceci impose la conception de produits fonctionnels et respectant les normes, dans des délais les plus courts possibles. Pour répondre à ces besoins, il faut prendre en compte la CEM au plus tôt dans le design. Dans le contexte de conception de carte électroniques, deux problèmes demeurent pour parvenir à cet objectif. Premièrement, les contraintes normatives définies au niveau de l’équipement sont difficiles à décliner au niveau de la carte. Deuxièmement, beaucoup de paramètres sont indéterminés en amont de la conception, rendant difficile l’analyse et la prise de décision. Ce mémoire propose de répondre à ces problématiques dans le cadre d’une étude d’émissivité rayonnée. Pour cela, une démarche de création de modèle paramétrique de rayonnement de carte électronique est proposée. L’utilisation de la puissance totale rayonnée (PTR) comme sortie du modèle sert de passerelle entre une représentation de la carte et celle de mécanique, au niveau système, répondant à la première problématique. Le modèle de carte électronique ainsi obtenu doit être capable de réaliser une analyse de sensibilité pour répondre à la deuxième problématique. L’utilisation de méta-modèles sur la simulation numérique permet d’obtenir des modèles à la fois rapides et fiables. Cette méthode, proposée dans cette thèse, est éprouvée sur des scénarios d’une relative complexité, pour démontrer son utilité dans la prise de décision lors de la conception d’un circuit imprimé
Today electronic systems market is very competitive. From an EMC point of view, it implies designing functional products, which pass EMC standards, in a minimum amount of time. To meet these needs, designers have to consider EMC as soon as possible in their design. In the context of electronic board design, there are two challenges to reach this goal. Firstly, the constraints in standards are equipment-level defined. Convert them to a board level is hardly accessible. Secondly, many parameters are undetermined at the beginning of the design, which prevents analysis and decision-making. This dissertation put forward some answers in a radiated emissivity context. To do so, a procedure to create a parametric model for the emissivity of an electronic board is proposed. The total radiated power as output of the model consists of the input at a system level model. This solves the first problem. The model built must be able to provide a sensitivity analysis to solve the second problem. Surrogate modeling based on electromagnetic (but time and resource consuming) simulation offers reliable and fast models. This is the methodology proposed by this thesis. It is tested on scenarios of moderate complexity, to prove how useful it is in decision-making during the conception of a stackup of a board

Examensarbetet inom produktutveckling – konstruktion utfördes under perioden februari till juni 2013 och omfattar 15 högskolepoäng (C-nivå), och är den slutliga kursen inom högskoleingenjörsprogrammet Innovation och produktdesign. Examensarbetet behandlade problematiken kring produktionsanpassning och kostnadsoptimering av två stycken elektromagnetiska omrörare vid företaget ABB, Process Automation, Metallurgy i Västerås. Efter kontakt med handledaren från ABB, Jan-Erik Eriksson, påbörjades projektarbetet med att tillverkningsanpassa konstruktionen av produkterna ORD 43P och EM Stabilizer. För att åstadkomma kostnadsoptimerad och produktionsanpassad konstruktion tillämpade författarna följande produktutvecklingsverktyg: Design for Cost, Design for Manufacture och Design for Assembly. För att kontrollera att konstruktionen blev optimal, men också att den inte brister under belastning använde examensarbetarna det datorbaserade hållfasthetsverktyget finita elementmetoden i CAD-programmet SolidWorks. Val av komponenter baserades på komponenternas pris per kilo. För att välja det optimala materialet, det vill säga högsta hållfasthet till lägsta pris använde författarna materialdatabasprogrammet CES EduPack. De utvalda materialen från programmet kunde inte författarna påfinna som standard på marknaden, varför författarna ändrade strategi till att jämföra och välja material utifrån marknadsundersökning av standardmaterial hos leverantörer.   ORD 43Ps komponenter optimerades konstruktionsmässigt gentemot befintliga komponenter och härvstag och isolerplattor kostnadsreducerades markant. Komponenten stomme grundutförande undersöktes översiktligt.  Genom att produktutveckla komponenterna härvstag, isolerplattor och stomme grundutförande minskade kostnaderna för ORD 43P med 2,47 %.  Författarna ansåg att ORD 43Ps totala kostnader kan minska mellan 10-25 % eftersom många av dess komponenter är överdimensionerade och består av dyrare material än vad som krävs.  EM Stabilizer’s komponenter, lock och tryckluftsslang, utformades med optimal konstruktion och kostnadsreducerades.  Genom att produktutveckla komponenterna lock och tryckluftsslang minskade kostnaderna för EM Stabilizer med 1,3 %.  Författarna förmodar att EM Stabilizer’s kostnader kan minska, eftersom den är relativt ny på marknaden. ABB vill säkerställa att produkten uppnår sin garanterade livslängd genom att överdimensionera många av produktens komponenter och använda dyrare material än vad som är nödvändigt.
The thesis in product development – design was carried out between February and June 2013 and includes 15 credits (C-level), and is the final course of the Bachelor Program in Engineering, Innovation and Product Design.  The thesis dealt with the problem of adaptation to production and cost optimization of two pieces of electromagnetic stirrers at the company ABB, Process Automation, Metallurgy in Västerås. After contact with the supervisor from ABB, Jan-Erik Eriksson, the project work commenced to adapt the manufacturing design of the product ORD 43P and EM Stabilizer. To achieve cost-optimized production and production adapted design, the authors applied the following product development tools: Design for Cost, Design for Manufacture and Design for Assembly. To verify that the design was optimal, but also that it did not break during stress, the authors used the computer based module finite element method of the CAD program SolidWorks.  The selection of components was based on the component’s price per kilo.  To select the optimum material, that is high strength and affordable, the authors used the material database software CES EduPack. The materials selected from CES EduPack could not be found by the authors as standard material at the market. Therefore, the authors changed strategy to compare and select materials based on market research of standard materials with suppliers. The components of ORD 43P were optimized in terms of design in comparison with existing components coil bracket and insulation boards. They were also cost reduced significantly. The component frame base was examined briefly.  Through product development the components coil bracket, insulating boards and frame base the total cost of ORD 43P was reduced by 2,47 %.  The authors found that the total cost of ORD 43P could be reduced between 10-25 % as many of its components are oversized and made ​​of more expensive materials than needed.  The components of EM Stabilizer, cover and pneumatic hose, were designed with optimum design and was cost reduced.Through product development the components cover and pneumatic hose the costs of EM stabilizer were reduced by 1,3 %.  The authors assume that the costs of the EM Stabilizer can be reduced, because it is relatively new at the market. ABB want to ensure that the product reach its guaranteed life by over-sizing many of the components of the product and use more expensive material than necessary.

The study catered for empirical and metaphysical dimensions of science and IKS. The study employed a quasi-experimental design as well as a qualitative research design. Two cohorts of students from a fictitiously named &ldquo
Culture Secondary School&rdquo
have been used in this study. The list of instruments for data collection were as follows: Conceptions of Fermentation (COF) questionnaire which was used to elicit learners&rsquo
pre- and post-test conceptions of fermentation with special reference to traditional beer or &ldquo
Umqombothi&rdquo
, an Attitudes to Science (ATS) questionnaire which was used to find out the learners&rsquo
worldviews, a Science Achievement Test (SAT) which was used to assess the learners&rsquo
generalised knowledge of fermentation, a classroom observation schedule as well as a focus group interview schedule to gather additional qualitative data. All the instruments were in English with all technical and difficult terms in both English and isiXhosa (the learners&rsquo
home language). Both groups were exposed to Science/IKS-based lessons. The only difference between the two groups was that, the experimental group (E group) was exposed to a Dialogical Argumentation Teaching Model (DAIM) and the comparison group (C group) to a traditional teaching approach. The data gatherred were both analyzed in terms of qualitative and quantitative descriptions.

The purpose of this thesis is to present solutions to overcome several key difficulties that limit the application of numerical modelling in communication cable design and analysis. In particular, specific limiting factors are that simulations are time consuming, and the process of comparison requires skill and is poorly defined and understood. When much of the process of design consists of optimisation of performance within a well defined domain, the use of artificial intelligence techniques may reduce or remove the need for human interaction in the design process. The automation of human processes allows round-the-clock operation at a faster throughput. Achieving a speedup would permit greater exploration of the possible designs, improving understanding of the domain. This thesis presents work that relates to three facets of the efficiency of numerical modelling: minimizing simulation execution time, controlling optimization processes and quantifying comparisons of results. These topics are of interest because simulation times for most problems of interest run into tens of hours. The design process for most systems being modelled may be considered an optimisation process in so far as the design is improved based upon a comparison of the test results with a specification. Development of software to automate this process permits the improvements to continue outside working hours, and produces decisions unaffected by the psychological state of a human operator. Improved performance of simulation tools would facilitate exploration of more variations on a design, which would improve understanding of the problem domain, promoting a virtuous circle of design. The minimization of execution time was achieved through the development of a Parallel TLM Solver which did not use specialized hardware or a dedicated network. Its design was novel because it was intended to operate on a network of heterogeneous machines in a manner which was fault tolerant, and included a means to reduce vulnerability of simulated data without encryption. Optimisation processes were controlled by genetic algorithms and particle swarm optimisation which were novel applications in communication cable design. The work extended the range of cable parameters, reducing conductor diameters for twisted pair cables, and reducing optical coverage of screens for a given shielding effectiveness. Work on the comparison of results introduced ―Colour maps‖ as a way of displaying three scalar variables over a two-dimensional surface, and comparisons were quantified by extending 1D Feature Selective Validation (FSV) to two dimensions, using an ellipse shaped filter, in such a way that it could be extended to higher dimensions. In so doing, some problems with FSV were detected, and suggestions for overcoming these presented: such as the special case of zero valued DC signals. A re-description of Feature Selective Validation, using Jacobians and tensors is proposed, in order to facilitate its implementation in higher dimensional spaces.

The context of this investigation is a study on the integration of design in the furniture making sector during the period of the national economy’s opening, by the end of the twentieth century. This work was undertaken through an approach focused on the effects of the country’s entry in the European Economic Community upon its industry and the strategies that were adopted by the furniture-making industries to face foreign competition. This study aims to understand the integration of design on the furniture making industry, within the context of the sector’s evolution after the country’s entry on the EEC. This is a pertinent research as studies on both Portuguese design and the national furniture making sector are very scarce, whereby it can serve as a basis for future reflections on how to undertake interventions within this sector. An attempt to contribute towards the theoretical development of the Portuguese design studies and its relation with the furniture making sector was thus made. Methodologically wise, this work resorted to qualitative analysis above all else. Literary revision was complemented with case studies related to the course of two national and furniture making corporations as well as a foreign one. In order to depict the industrial sector, the statistical data from the period between the 1990’s and 2015 were analyzed and tables and charts that allow a better reading of the displayed information. The furniture’s characterization was elaborated through the observation and analysis of images obtained in national home decoration magazines. This study also contains seven interviews that were made to representatives of corporations belonging to the sector and a chronological table that places the more important events related to design and the industrial development that touched upon during the course of this work side by side. The main conclusion concerns the problems of design’s integration in the furniture-making industry and the profession’s regulations. The effects of the country’s entry in the EEC have had opposite repercussions upon the development of the industry and design in itself. During the 1990’s, the industry had gone through a serious crisis period. Simultaneously, a great interest for design, as well as several financial resources that were used to support the promotion of this activity, appeared. Both these activities ended up developing separately

abstract: This research aims to investigate the social environment in a brand-new type of café, pet café, and to maximum the benefit of this type of cafe. While pet cafés, especially cat cafés, are becoming increasingly common in the United States (U.S.), Asian countries have been in this kind of business since 1998. The most common and popular is the cat café. Even though the owners of cat cafés in the U.S. have learned and imitated the cat café in Asia, the cultural differences and the restrictions resulted in differences in format and design. Interior and furniture design was investigated to afford motivation to people who are pet lovers and can be potential customers. Most of the research about pets illustrates a positive influence on psychological health and social support. On the other hand, a café with pets can be attractive and interactive more than a general café, to offer a recreational activity and a comfortable social environment and therapy from pets. Juxtaposing the cat café in the U.S. against the pet café in China, is explored to investigate the difference between these countries and how they can learn from each other and make improvements to design. Research on what is the difference between the cat café in the U.S. and China are reflected on two parts of outcomes—design and business.

Capillary electrochromatography (CEC) is a major capillary electrophoresis (CE) mode that have been interfaced to mass spectrometry (MS) for sensitive and selective analysis of chiral compounds. This research expands CEC applications in cancer biomarker and chiral CE analysis. Chapter 1 is a review of liquid chromatography-mass spectrometry (LC/MS), gas chromatography-mass spectrometry (GC/MS), and capillary electrophoresis mass spectrometry (CE/MS) for analysis of metabolites in prostate cancer diagnostics and therapies. In this chapter, a literature survey was performed within the databases PubMed, 4 Caplus/Webline and Web of Sciences. A total 17 studies reporting on various analytical platforms for metabolite identification in prostate cancer research, which often include case-control comparison were identified and reviewed. Chapter 2 described the analysis of metabolite biomarkers in prostate cancer tissues by capillary electrochromatography mass spectrometry. In this chapter, a capillary CEC–MS/MS method was developed for the simultaneous determination and separation of eight proofs of concept (POC) metabolites (betaine, malate, proline, N-acetyl aspartate, N-acetylglucosamine, uracil, xanthine, and alanine) as potential prostate cancer diagnostic markers. A polymeric monolith column with a hydrophilic crosslinker and strong anion-exchange mixed-mode has been fabricated by an in situ copolymerization of vinyl benzyl trimethylammonium chloride, and bisphenol A glycerolate dimethacrylate (BisGMA) in the presence of methanol and dodecyl alcohol as porogens and AIBN as initiator. After CEC separation, samples were analyzed by a triple–quadrupole mass spectrometer operated in positive ion mode. After optimization, the data showed that the CEC-MS/MS method using monolithic column achieved a much better chromatographic selectivity compared to coated columns and increased sensitivity than bare fused silica column The effect of mobile phase pH, ACN percentage and additive were studies. Under the optimum mobile phase conditions, this method was carried out to separate and detect eight metabolites in the biopsy sample. The LOD for the metabolites is between 50nM-100nM. This method has successfully used to examine patients’ prostate cancer with an accuracy of 95%. Chapter 3 demonstrates Insights into Chiral Recognition Mechanisms in CEC using linear salvation energy relationship. By varying the linker (amide and carbamate), head group (alanine, leucine, and valine) and chain length (C8, C10 and C12) of the amino acid bound surfactants; monolithic column was made to ultimately understand the factors governing chiral stationary solid phase. Through the comparison of system parameters, we can see that surfactant head group, linker and chain length affect the separation of achiral and chiral compounds. Also, with the same type surfactant, data was presented to show how the trend of LSER parameters and how it affects separation between in CEC. This study showed the predictive capability of LSER to understand the aforementioned intermolecular processes controlling retention and by doing so, be able to quantitatively predict the experimental conditions to achieve an acceptable chiral separation.

The purpose of this study was to propose and evaluate a procedure for revising an existing self-administered survey that is in need of item revision and/or scale reduction while maximizing validity and reliability. The procedure was demonstrated using the Client Evaluation of Self and Treatment (CEST; Joe, Broome, Rowan-Szal, & Simpson, 2002), a self-administered survey used in drug and alcohol treatment agencies. The procedure included confirmatory and exploratory factor analyses of a large dataset of completed CEST surveys, a readability analysis, and cognitive interviewing of two different groups of respondents to determine what problems they might have with CEST items. The cognitive interviewing revealed a number of issues that led to confusion among respondents, including items with two distinct concepts embedded, items containing absolutes and vague qualifiers, misinterpreted items, and terms and phrases respondents had difficulty understanding. The CEST was also judged to be long and potentially burdensome to respondents. Based on the results of this evaluation, a new survey—the Brief Assessment of Self in Context (BASIC)—also intended for use by substance abuse treatment providers, was constructed. First, factor analyses of the CEST and advice from an expert panel were used to determine which scales to retain. Next, quantitative analyses and cognitive interviewing helped determine which CEST items to retain and which to revise. Readability, sound item writing principles, and response format and scale requirements were also used to determine which items to include in the initial draft of the BASIC and guided item construction when needed. After the panel of experts provided feedback on the first revision, a final draft was prepared. Another round of cognitive interviewing was followed by administration of the final draft of the survey to a representative sample. The results indicated that the BASIC’s items are clear, unambiguous, and easy to interact with and understand, and that the instrument is an improvement over the CEST. In brief, the procedure demonstrated in this study produced a psychometrically sound instrument composed of items that are easy for respondents to access.

Globally, there is a need for alternative building materials that require less energy to produce than conventional materials. These alternative materials have gained popularity in recent years, however there is a need to better understand their physical properties in order to increase confidence in their use. As such, a testing program was undertaken to investigate the structural properties of some of these materials. A series of compressed earth blocks made from a mixture of earth and cement compressed to 8 - 12 MPa were tested for their compressive capacity in masonry prisms. The blocks had been weathered for one to two years. The blocks with no cement had a capacity of 2.22 MPa, while cement stabilized blocks had a capacity of 8.11 MPa. Weathering did not result in any significant reduction in the strength of the blocks. Bales of high density straw were tested both with and without cement plaster skins. Unplastered bales exhibited a stiffness between 0.3 - 0.7 MPa when oriented Flat, and 1.2 MPa on edge. The bales had a dilation ratio between 0.1 - 0.3 in the Flat orientation and averaging 3.5 in the Edge orientation. The high density bales plastered with cement plaster exhibited ultimate strengths averaging 171.2 kN/m. Capacity was heavily dependent on plaster strengths, and when normalized for plaster strengths, high density bales had capacities lower than those of regular density bales tested previously (34.1 kN/m/MPa compared to 44.3 kN/m/MPa). Three walls made of straw with cement plaster were constructed with pin-ended conditions to study the effects of buckling in straw bale walls. The average capacity was 12.8 kN/m/MPa when normalized for plaster strength. Pin ends resulted in plastic hinges forming more easily in the walls, and pin ended specimens had a 75% reduction in strength compared to previous tests of "standard" end conditions. Taller walls also resulted in reduced strengths.

A presente tese relata o trabalho de investigação levado a cabo com o propósito de desenvolver uma aplicação móvel (app) para Educação em Ciências no 1.º Ciclo do Ensino Básico (1.º CEB), integrando um framework de exploração de dados educacionais (Educational Data Mining – EDM) com o intuito de promover o desenvolvimento de competências científicas e a autorregulação das aprendizagens pelos alunos. Para tal, adotou-se a abordagem metodológica Educational Design Research, que prevê várias técnicas de recolha de dados, e a participação de diferentes intervenientes, de acordo com três fases interativas e iterativas: Estudo preliminar, Fase de prototipagem e Fase de avaliação. No Estudo preliminar, entre outros momentos e técnicas, foi implementado um questionário a professores do 1.º CEB (n=118), com o propósito de definir e/ou validar os seguintes aspetos: (i) o público-alvo – alunos do 4.º ano de escolaridade; (ii) o tema a abordar na app no âmbito da Educação em Ciências – Corpo Humano; (iii) os conteúdos educativos digitais a integrar na app – animações (interativas) , jogos, simulações, quizzes e áreas informativas; (iv) a abordagem de aprendizagem da app relacionando os princípios do Universal Design for Learning e as abordagens Inquiry-Based Science Education e BSCS 5E; e (v) as componentes de gestão das aprendizagens da app – feedback formativo, recomendações e ajudas em tempo real, desencadeadas pela app de acordo com o framework de EDM conceptualizado. Com base nos resultados anteriores, nomeadamente o público-alvo e o tema a abordar na app, foi implementada uma atividade de escrita e desenho criativos com alunos do 4.º ano de escolaridade (n=25), com o propósito de definir o conceito da app: (vi) o tópico no âmbito da Educação em Ciências a abordar na app – Alimentação saudável (e atividade física); (vii) os subtópicos a abordar; (viii) as personagens da app; e (ix) os ambientes gráficos da app (e.g., horta). De acordo com a definição da abordagem de aprendizagem e das componentes de gestão das aprendizagens foi definida a Estrutura relacional do framework conceptual de EDM para Educação em Ciências, ou seja, as questões “colocadas” à app no decorrer da exploração/interação e os eventos lidos pela mesma através dos métodos e técnicas de EDM adotados. Por último, com base no estado da arte de apps portuguesas para Educação em Ciências, no Estudo preliminar definiram-se as especificações gráficas e funcionais da app: principais ecrãs, botões e áreas da app. Na Fase de prototipagem, foi implementada uma sessão de focus group com especialistas em User Experience (Design), com o propósito de validar as especificações gráficas e funcionais da app. Com base nas evidências recolhidas na sessão, definiu-se o Wireflow da app: estrutura dos ecrãs da app, relação entre os ecrãs, disposição de elementos gráficos, funcionalidades previstas e ações dos botões da app. Com base na análise de documentos orientadores, foram definidas as especificações didáticas da app: conteúdos educativos a abordar; e aprendizagens esperadas com a exploração da app. A definição das especificações didáticas permitiu o desenvolvimento dos scripts e storyboards dos conteúdos educativos digitais da app. Por último, o Framework conceptual de exploração de dados educacionais para Educação em Ciências da app foi desenhado de acordo com 11 (onze) algoritmos gráficos, de forma a representar o conjunto dos processos, ações e operações que visam a promoção do desenvolvimento de competências científicas e a facilitação do processo de autorregulação das aprendizagens pelos alunos. Na Fase de avaliação, entre outros aspetos, os protótipos desenvolvidos foram validados: (i) Wireflow da app; (ii) scripts e storyboards dos conteúdos educativos digitais da app; e (iii) Framework conceptual de exploração de dados educacionais para Educação em Ciências. Entre outras, as principais conclusões retiradas no estudo de acordo com as conceções de professores do 1.º CEB (n=118) foram (i) a importância do desenvolvimento da app proposta para alunos do 4.º ano de escolaridade do 1.º CEB na área temática Corpo Humano; (ii) a adequação da abordagem de aprendizagem proposta para a app e das cinco tipologias de conteúdos educativos digitais, face ao seu potencial para promover uma aprendizagem em Educação em Ciências de carácter integrador e prático, e para promover o desenvolvimento de competências científicas; e (iii) a adequação da disponibilização em tempo real das três componentes de gestão das aprendizagens propostas, permitindo facilitar e potenciar as aprendizagens, e personalizar a experiência de utilização e o percurso de aprendizagem de cada aluno, apoiando e ajudando os alunos ao longo da exploração da app e dos conteúdos educativos digitais de acordo com o seu desempenho educativo. Importa, ainda, destacar algumas das principais conclusões que emergiram das opiniões e sugestões dos especialistas: (iv) a adequação dos cinco ecrãs principais, botões e áreas da app, definidos nas especificações gráficas e funcionais e refletidos no wireflow da app – validado por três especialistas externos ao projeto em User Experience Design; (v) a adequação dos conteúdos educativos a abordar na app e das aprendizagens esperadas com a sua exploração, definidos nas especificações didáticas e refletidos no scripts e storyboards da app – validados por quatro especialistas externos ao projeto em Didática das Ciências, Multimédia em Educação, Guionismo e Nutrição e Saúde Alimentar; e (vi) a adequação das questões e eventos lidos pela app com recurso aos métodos e técnicas de EDM adotados, refletidos no Framework conceptual de exploração de dados educacionais para Educação em Ciências e que representa o conjunto dos processos, ações e operações que visam a promoção do desenvolvimento de competências científicas e a facilitação do processo de autorregulação das aprendizagens pelos alunos – validado por três especialistas externos ao projeto em Algoritmia e Técnicas de Representação de Algoritmos e Algoritmia de Avaliação de Desempenho. A aplicação das várias técnicas de recolha de dados, a participação de diferentes intervenientes, e os vários processos e momentos de validação implementados, permitiram validar as decisões e opções tomadas, atribuindo aos produtos de investigação e às conclusões do estudo coerência, rigor científico, validade de conteúdo e de conceito, fiabilidade, e um carácter participativo e centrado no utilizador.
The present thesis reports research work related to a study aimed at developing a Science Education mobile application (app) for primary-school students, integrating an Educational Data Mining (EDM) framework to enhance the students' scientific competences development and self-regulated learning. For that, the Educational Design Research approach was adopted, which foresees several data collection techniques, and the participation of different stakeholders, according to three interactive and iterative phases: Preliminary Research, Prototyping Phase and Evaluation Phase. In the Preliminary Research, among others, a questionnaire was implemented among primary school teachers (n=118), to define the mobile app, namely (i) the target audience – 4 th grade primary-school students; (ii) the Science Education topic to approach in the mobile app – Human Body; (iii) the digital educational contents to integrate in the mobile app – animations, games, simulations, quizzes and information areas; (iv) the app’s learning approach – an authoring one, relating the Universal Design for Learning principles and the Inquiry Based Science Education and BSCS 5E approaches; and (v) the app’ learning management components – formative feedback, recommendations and real time help, triggered by the mobile app according to the EDM framework. Based on these, a creative writing and drawing activity was implemented with the target audience (n=25), to define the mobile app concept: (vi) the Science Education topic to approach – Healthy eating (and physical activity); (vii) the sub-topics to approach; (viii) the mobile app’s characters; and (ix) the mobile app’s graphical environments (e.g., kitchen garden). According to the learning management components definition, the relational structure of the EDM framework was defined, i.e., the questions "asked" to the system and the events read by the mobile app through the adopted EDM methods and techniques. Finally, based on the state of the art of Portuguese mobile apps for Science Education, the mobile app’s graphic and functional specifications were defined: main screens, buttons, and the app’s areas. In the Prototyping Phase, a focus group session was implemented with User Experience experts, validating the mobile app’s graphic and functional specifications. Based on document analysis, the mobile app’s didactic specifications were defined: the focussed scientific contents; the learning goals; and the expected scientific competences to develop with the mobile app’s usage. This definition allowed to develop the mobile app’s digital educational contents scripts and storyboards. Finally, the mobile app’s EDM framework was designed according to 11 (eleven) flowcharts, i.e., how the mobile app “answers” to the students’ actions, helping them to develop scientific competences and promoting their self regulated learning. Finally, in the Evaluation Phase, among other aspects, the mobile app’s prototypes were validated: (i) the mobile app’s wireflow; (ii) the digital educational contents scripts and storyboards; and (iii) the EDM framework. Among others, the main study conclusions according to the primary-school teachers conceptions (n=118) were: (i) the relevance of the proposed app development for the 4 th grade primary-school students related to the Human Body topic; (ii) the adequacy of the proposed learning approach and the five typologies of digital educational resources defined for the app, regarding its potential to promote a comprehensive and practical learning approach in Science Education, and to promote the development of scientific competences; and (iii) the adequacy of the real time availability of the three proposed learning management components, allowing to facilitate and enhance learning, and to tailor the students’ user experience and learning path, by supporting and helping them through the app’s digital educational resources exploration according to their educational performance. From the main conclusions, it is also important to highlight those that emerged from the experts’ conceptions and suggestions: (iv) the adequacy of the five app’s main screens, buttons and areas, defined within the graphic and functional specifications and reflected in the app’s wireflow – validated by three external experts in User Experience Design; (v) the adequacy of the educational contents to be addressed in the app and the expected learning outcomes with its exploration, defined in the didactic specifications and reflected in the scripts and storyboards of the app – validated by four external experts in Science Education, Multimedia in Education, Screenwriting, and Food Nutrition and Health; and (vi) the adequacy of the issues and events read by the app according to the adopted EDM methods and techniques, reflected in the conceptual EDM framework for Science Education, representing the set of processes, actions and operations aiming at to promote the students’ scientific competences development and to facilitate students’ self-regulated learning – validated by three external experts in Algorithms and Techniques of Algorithms Representation, and Performance Evaluation Algorithms. The various data collection techniques, the participation of different stakeholders, and the different validation processes and moments of the study allowed to validate the study decisions and options, assigning to the study coherence, scientific accuracy, content and concept validity, reliability, and a participatory and user-centred approach regarding the scientific outcomes and the final conclusions

This study was motivated by a desire to address the challenges of introductory programming courses. Ethiopian universities teach such courses in large classes (80+ students) and students complain about the difficulty of the courses and teaching variation of instructors. The study was set to explore optimum course and learning environment design approaches. The research question raised was: how can a blended learning approach be used to improve large class teaching of programming? In an action design research approach, the study was initiated with redesigning two consecutive courses and a supportive blended learning environment on the basis of existing learning theories and educational design frameworks. Two cycles of action research were conducted for a dual goal of refinement and evaluation of the intervention. The action research was conducted during the 2012/13 academic year with 240 students at the beginning. A predominantly quantitative first cycle of action research produced a mixed outcome. The students’ marks from assessment activities were fairly close to results from two other international universities. A pre- and post-implementation survey of students’ approach to learning showed a slight class level change towards the deep learning approach. Conversely, some students were found at-risk (not progressing well) and certain technologies, particularly program visualisation tools, were found underutilised. The second action research cycle aimed to explain the result from the first round. A grounded action research evaluation of data from focus group discussions, interviews and participants’ memos identified plausible factors for meaningful programming learning in a large class. These factors were use of collaborative and pair programming; alignment of learning and assignment activities; integrated use of e-learning; and use of large class strategies like student mentors and team teaching. A critical realist interpretation of the result of the action research suggested that students can learn programming in large classes, 200+ in this study, with a course and learning environment design that keeps them engaged in learning and assessment activities. The study concludes that improved learning of programming can be possible with the use of students as mentors and changed role-dynamics of instructors, which presupposes adaptation of suitable pedagogical approaches and use of technologies.

Le trouble d’anxiété de séparation (TAS) est le trouble anxieux le plus prévalent chez les enfants. Il apparaît tôt et entraîne plusieurs conséquences négatives. La thérapie cognitivo-comportementale (TCC) a été reconnue efficace pour traiter les troubles anxieux. Toutefois, peu d’études ont vérifié son efficacité pour le traitement spécifique du TAS et très peu en ont examiné l’effet auprès d’enfants de moins de 7 ans. Les quelques interventions étudiées visant les moins de 7 ans ont en commun d’inclure le parent dans le traitement ou de l’offrir directement à celui-ci. L’objectif principal de cette thèse est de vérifier l’efficacité d’un programme d’entraînement parental de type TCC, adapté pour les parents d’enfants de 4 à 7 ans souffrant de TAS. Cette étude vise également deux objectifs spécifiques : observer la fluctuation des symptômes de TAS de l’enfant pendant le traitement et examiner l’impact du programme sur les variables parentales. Un devis à cas unique à niveaux de base multiples a été utilisé. Six familles ont pris part à l’étude. Des entrevues semi-structurées, des questionnaires auto-administrés et des calepins d’auto-observations quotidiennes ont été utilisés auprès des parents pour mesurer les symptômes anxieux des enfants, leurs pratiques parentales, le stress parental et leurs symptômes anxieux et dépressifs. Des questionnaires sur les difficultés de l’enfant incluant l’anxiété ont aussi été envoyés à l’éducatrice ou à l’enseignante. Tous les questionnaires ont été administrés aux trois temps de mesure (prétraitement, post-traitement et relance 3 mois). Les calepins d’auto-observations ont été remplis quotidiennement durant le niveau de base, pour toute la durée de l’intervention et pendant une à deux semaines à la relance. Les résultats de l’étude indiquent que cinq enfants sur six ne répondent plus au diagnostic de TAS suite au traitement ainsi que trois mois plus tard. Les résultats des calepins d’auto-observations montrent une amélioration claire des manifestations principales de TAS pour la moitié des enfants et plus mitigée pour l’autre moitié, de même qu’une amélioration systématique de la fréquence hebdomadaire totale de manifestations de TAS suite à l’intervention pour quatre enfants. Les résultats aux questionnaires remplis par les parents montrent une amélioration des symptômes d’anxiété et de TAS chez quatre enfants au post-test et/ou à la relance, tandis que les questionnaires de l’éducatrice (ou enseignante) suggèrent que les symptômes anxieux des enfants se manifestaient peu dans leur milieu scolaire ou de garde. L’impact du programme sur le stress parental et les pratiques parentales est également mitigé. Ces résultats suggèrent que le Programme d’entraînement parental pour les enfants souffrant d’anxiété de séparation (PEP-AS) est efficace pour réduire les symptômes de TAS chez les enfants d’âge préscolaire ou en début de parcours scolaire et appuient la pertinence d’offrir le traitement aux parents et d’inclure un volet relationnel. D’autres études seront cependant nécessaires pour répliquer ces résultats auprès d’un plus vaste échantillon. Il serait également intéressant de vérifier les effets indépendants des différentes composantes du traitement et d’évaluer les effets du programme sur davantage de pratiques parentales associées spécifiquement à l’anxiété.
Separation anxiety disorder (SAD) is the most prevalent anxiety disorder among children. It appears early in development and has multiple negative consequences. Cognitive-behavioral therapy (CBT) has been shown to be an effective treatment for anxiety disorders. However, few studies have examined the efficacy of CBT to treat SAD in particular, and even fewer have examined the impact of this form of therapy on children younger than 7 years old. The main objective of the present doctoral thesis was to evaluate the efficacy of a CBT parent-training program, that was adapted specifically for parents of children aged 4 to 7 years old suffering from SAD. This study had two specific objectives: to observe any fluctuations in the child’s SAD symptoms during the treatment and to examine the impact of the program on parental variables. A single-case multiple baseline across-subjects design was used. Six families with a child aged 4-7 years old and with a diagnosis of SAD participated. Semi-structured interviews, self-reported questionnaires and daily diaries were used with the parents to assess the child’s anxiety symptoms, parental practices, parenting stress, and the parents anxious and/or depressive symptoms. Questionnaires on child problems were also sent to the children’ teacher or educator. All questionnaires were administered at three times of measurement (pre-treatment, post-treatment and 3 months follow-up). Daily diaries were also completed by the parents at baseline, throughout the treatment, and during one to two weeks at follow-up. Results revealed that five of the six children no longer met the criteria of a SAD diagnosis after treatment and three months later. Findings from the daily diaries showed a clear reduction of the principal SAD symptoms for half of the children but mixed results for the other half of the children and that four of six children presented a systematic favourable change of the total weekly frequency of SAD symptoms after the intervention. The results of parent questionnaires showed an improvement of SAD symptoms for four children at post-treatment and/or follow-up. The teacher/educator questionnaires indicated low impact of anxiety symptoms. The impact of the program on parenting stress and parental practices is mixed with some parents showing improvement and others less so. The results support the efficacy of the Programme d’entraînement parental pour les enfants souffrant d’anxiété de séparation (PEP-AS) to reduce SAD symptoms in preschool age children and support the relevance of directing the treatment towards parents and including a relational component in the intervention. However, more research is needed to replicate these findings with larger samples and randomized control trials. It would also be interesting to dismantle the program and to examine the various components of the treatment in different combinations, and to explore more specifically the program effects on parental variables.
