Full textAbstract:
Un système de surveillance environnementale collecte et analyse continuellement les flux de données générés par les capteurs environnementaux. L'objectif du processus de surveillance est de filtrer les informations utiles et fiables et d'inférer de nouvelles connaissances qui aident l'exploitant à prendre rapidement les bonnes décisions. L'ensemble de ce processus, de la collecte à l'analyse des données, soulève deux problèmes majeurs : le volume de données et la qualité des données. D'une part, le débit des flux de données générés n'a pas cessé d'augmenter sur les dernières années, engendrant un volume important de données continuellement envoyées au système de surveillance. Le taux d'arrivée des données est très élevé par rapport aux capacités de traitement et de stockage disponibles du système de surveillance. Ainsi, un stockage permanent et exhaustif des données est très coûteux, voire parfois impossible. D'autre part, dans un monde réel tel que les environnements des capteurs, les données sont souvent de mauvaise qualité, elles contiennent des valeurs bruitées, erronées et manquantes, ce qui peut conduire à des résultats défectueux et erronés. Dans cette thèse, nous proposons une solution appelée filtrage natif, pour traiter les problèmes de qualité et de volume de données. Dès la réception des données des flux, la qualité des données sera évaluée et améliorée en temps réel en se basant sur un modèle de gestion de la qualité des données que nous proposons également dans cette thèse. Une fois qualifiées, les données seront résumées en utilisant des algorithmes d'échantillonnage. En particulier, nous nous sommes intéressés à l'analyse de l'algorithme Chain-sample que nous comparons à d'autres algorithmes de référence comme l'échantillonnage probabiliste, l'échantillonnage déterministe et l'échantillonnage pondéré. Nous proposons aussi deux nouvelles versions de l'algorithme Chain-sample améliorant sensiblement son temps d'exécution. L'analyse des données du flux est également abordée dans cette thèse. Nous nous intéressons particulièrement à la détection des anomalies. Deux algorithmes sont étudiés : Moran scatterplot pour la détection des anomalies spatiales et CUSUM pour la détection des anomalies temporelles. Nous avons conçu une méthode améliorant l'estimation de l'instant de début et de fin de l'anomalie détectée dans CUSUM. Nos travaux ont été validés par des simulations et aussi par des expérimentations sur deux jeux de données réels et différents : Les données issues des capteurs dans le réseau de distribution de l'eau potable fournies dans le cadre du projet Waves et les données relatives au système de vélo en libre-service (Velib)An environmental monitoring system continuously collects and analyzes the data streams generated by environmental sensors. The goal of the monitoring process is to filter out useful and reliable information and to infer new knowledge that helps the network operator to make quickly the right decisions. This whole process, from the data collection to the data analysis, will lead to two keys problems: data volume and data quality. On the one hand, the throughput of the data streams generated has not stopped increasing over the last years, generating a large volume of data continuously sent to the monitoring system. The data arrival rate is very high compared to the available processing and storage capacities of the monitoring system. Thus, permanent and exhaustive storage of data is very expensive, sometimes impossible. On the other hand, in a real world such as sensor environments, the data are often dirty, they contain noisy, erroneous and missing values, which can lead to faulty and defective results. In this thesis, we propose a solution called native filtering, to deal with the problems of quality and data volume. Upon receipt of the data streams, the quality of the data will be evaluated and improved in real-time based on a data quality management model that we also propose in this thesis. Once qualified, the data will be summarized using sampling algorithms. In particular, we focus on the analysis of the Chain-sample algorithm that we compare against other reference algorithms such as probabilistic sampling, deterministic sampling, and weighted sampling. We also propose two new versions of the Chain-sample algorithm that significantly improve its execution time. Data streams analysis is also discussed in this thesis. We are particularly interested in anomaly detection. Two algorithms are studied: Moran scatterplot for the detection of spatial anomalies and CUSUM for the detection of temporal anomalies. We have designed a method that improves the estimation of the start time and end time of the anomaly detected in CUSUM. Our work was validated by simulations and also by experimentation on two real and different data sets: The data issued from sensors in the water distribution network provided as part of the Waves project and the data relative to the bike sharing system (Velib)

COORDENAÇÃO DE APERFEIÇOAMENTO DO PESSOAL DE ENSINO SUPERIORA presente dissertação tem como objeto de estudo a análise dos discursos de empregabilidade e empreendedorismo através das representações elaboradas pelos atores sociais envolvidos no Programa Capacitação Solidária (PCS), viabilizados por três organizações capacitadoras na Região Metropolitana do Rio de Janeiro, no ano de 1999. Tendo como eixo norteador de análise a categoria de hegemonia nos termos gramsciano e de formação profissional no contexto brasileiro, o estudo assume uma perspectiva histórico estrutural. Assim, procura identificar as mediações históricas, econômicas, políticas e sociais presentes no processo de formação profissional hoje, no Brasil, constatando que esse exerce um papel importante na consolidação de uma nova hegemonia capitalista. Levando em consideração o público-alvo do PCS, a pesquisa assinala a difusão de conteúdos ambíguos de empregabilidade e empreendedorismo que acabam por criar uma prática contraditória e confusa a partir de uma representação em que ao mesmo tempo exalta e rejeita a inserção em atividades auto-geridas.
This dissertation aims at the analysis of the employability and enterprising discourses, through the exhibitions made by the social actors involved in the Solidarity Qualification Program, allowed by three qualifying organizations in Rio de Janeiro, in 1999. Having as guiding axis the hegemony category in the gramscian and professional graduating terms in Brazilian context, this studying assumes a historic-structural perspective. That being so, it aims at the identification of the historical, economical, political and social mediations that appears in the professional graduation process nowadays in Brazil, realizing that this exerts an important part in the consolidation of a new capitalism hegemony. Considering the Solidarity Qualification Program target public, the research calls the attention to the diffusion of ambiguous contents of employability and enterprising that creates a contradicting and confusing praxis from an exhibition in which, simultaneously, is exalted and refused the insertion in self- managed activities.

Full textAbstract:
International Telemetering Conference Proceedings / October 13-16, 1986 / Riviera Hotel, Las Vegas, NevadaThe Boeing Commercial Airplane Company presently uses an Airborne Data Analysis and Monitor System (ADAMS) to support extensive qualification testing on new and modified commercial aircraft. The ADAMS system consists of subsystems controlled by independent processors which preprocess serial PCM data, perform application-specific processing, provide graphic display of data, and manage mass storage resources. Setup and control information is passed between processors using the Ethernet protocol on a fiber optic network. Tagged data is passed between processors using a data bus with networking characteristics. During qualification tests, data are dynamically selected, analyses performed, and results recorded. Decisions to proceed or repeat tests are made in real time on the aircraft. Instrumentation in present aircraft includes up to 3700 sensors, with projections for 5750 sensors in the next generation. Concurrently, data throughput rates are increasing, and data preprocessing requirements are becoming more complex. Fairchild Weston Systems, Inc., under contract to Boeing, has developed an Acquisition Interface Assembly (AIA) which accepts multiple streams of PCM data, controls recording and playback on analog tape, performs high speed data preprocessing, and distributes the data to the other ADAMS subsystems. The AIA processes one to three streams in any of the standard IRIG PCM formats using programmable bit, frame and subframe synchronizers. Data from ARINC buses with embedded measurement labels, bus ID’s, and time tags may also be processed by the AIA. Preprocessing is accomplished by two high-performance Distributed Processing Units (DPU) operating in either pipeline or parallel environments. The DPU’s perform concatenation functions, number system conversions, engineering unit conversions, and data tagging for distribution to the ADAMS system. Time information, from either a time code generator or tape playback, may be merged with data with a 0.1 msec resolution. Control and status functions are coordinated by an embedded processor, and are accessible to other ADAMS processors via both the Ethernet interface and a local operator’s terminal. Because the AIA assembly is used in aircraft, the entire functional capability has been packaged in a 14-inch high, rack-mountable chassis with EMI shielding. The unit has been designed for high temperature, high altitude, vibrating environments. The AIA will be a key element in aircraft qualification testing at Boeing well into the next generation of airframes, and specification, design, development, and implementation of the AIA has been carried out with the significance of that fact in mind.

Full textAbstract:
The cylinder liners surface is of major importance in an engine since it interacts with the piston rings and creates a tribologic system. This tribologic system has to be qualified and controlled in order to understand and control wear, oil consumption and shelf life. In this purpose, a program has been created in order to analyze SEM pictures and from them qualify the surface.
The aim of the project presented here has been to improve the preliminary steps leading to the image computation by standardizing the picture acquisition and improve the image filtering.

Full textAbstract:
It has been well documented that the success of any public policy is closely linked to its development and implementation. Less research has considered how devolved nations tackle the complex and unstable nature of public policy making and address the challenges of implementing national policy. This thesis aims to provide an historical account of the development of one specific welsh education policy, created just after devolution. This thesis follows a single policy from its conception to worked reality. In particular, this thesis aims to uncover how one specific case created during this unique time period, post devolution, was developed and implemented, The Advanced Level Welsh Baccalaureate Qualification (WBQ). The WBQ education policy is of great significance to Wales’ reform agenda and has undergone radical revision, since devolution, making this research particularly timely. This thesis shows how the WBQ can be viewed as a flexible policy that can be adapted at the micro level, to create an education package best suited to the unique needs of the individuals and wider economic realities found across Wales. The WBQ aimed to tackle some of the most challenging educational issues, such as the academic vs. vocational education, specialisation vs. generalism and dealing with disaffection. The thesis draws on interviews with key stakeholders representing the macro, miso and micro, in 2012. The findings highlight the challenges of public policy making in devolved Wales and address how policy is made and who is actually developing policy. The findings of this thesis have suggested that key individuals at the macro level were crucial in shaping and developing the WBQ. The research offers new insights into the importance of considering implementation in the development of public policy. This thesis highlights how organisations and individuals involved in the implementation of public policy actually shape its finalised form in both subtle and more extensive ways during their translation and adaptation of policy. The degree of mutation that arises during translation impacts on the policies success in eventually becoming institutionalised. Variation itself is not unexpected given the flexibility but the findings demonstrate that this flexibility is causing a huge variation in quality and incomparable delivery and structure across institutions. The success of the policy is linked to its original aims and the issues within the Welsh education system it aims to tackle. The WBQ has been successful in achieving some of its original aims whilst others have remained unchanged.

Alexandre, dit Sandretto Julien. "Étalonnage des robots à câbles : identification et qualification." Thesis, Nice, 2013. http://www.theses.fr/2013NICE4059/document.
Full textAbstract:
L'objectif de cette thèse est de proposer des méthodes pour étalonner un robot parallèle à câbles de grande dimension. Afin d'améliorer le comportement global d'un robot, il est nécessaire d'identifier au mieux les paramètres de son modèle. Pour cela, il est important d'obtenir des informations redondantes en mesurant l'état du robot dans différentes configurations. Cependant, le modèle choisi est un compromis entre sa capacité à représenter le comportement réel du manipulateur et les informations disponibles pour le renseigner. Dans le cas particulier des robots à câbles de grande dimension, la masse et l'élasticité des câbles ont une influence non négligeable sur le comportement du robot mais sont difficiles à modéliser. En effet, le modèle physique des câbles est complexe et nécessite de connaître la tension à laquelle ils sont soumis. Les capteurs disponibles ne pouvant nous fournir cette information avec une précision suffisante pour renseigner un modèle de câble réaliste, nous proposons d'utiliser un modèle simplifié. Dans le but de proposer un étalonnage efficace, il est donc nécessaire de définir les conditions pour l'emploi de ce modèle simplifié. Ensuite, nous avons adapté et implanté d'une part plusieurs techniques classiques pour l'étalonnage des robots parallèles mais nous avons également élaboré des approches plus innovantes. Nous proposons en effet un modèle pour les robots à câbles reposant sur une représentation des incertitudes de modélisation, de mesures et de paramètres au moyen d'intervallesThe main objective of this thesis is to propose new methods for the calibration of a large scale cable-driven robot. The principal method to improve the global behavior of a robot consists to identify the parameters of the model. For this, it is important to get redundant information by measuring the state of the robot in different configurations. However, the model used is a compromise between its ability to represent the actual behavior of the manipulator and the information available to fill in it. In the special case of the large scale cable-driven robots, mass and elasticity of the cables have a significant influence on the behavior of the robot but they are difficult to model. Indeed, the physical model of the cable is complex and requires knowledge of the tension inside it. Available sensors cannot provide this information with a sufficient accuracy to fill in a model of a realistic cable, we thus propose to use a simplified model. In order to provide an efficient calibration, it is necessary to fix the requirements to use this simplified model. Then, we have adapted and implemented some classical techniques for the calibration of parallel robots, but we also developed more innovative approaches. We propose a model for cable robots based on a representation of the uncertainties from modeling, measurements and parameters using intervals. By exploiting the interval analysis, we have developed various approaches to identify with certification the geometric parameters of the structure. We thus propose a new approach and associated algorithms to characterize and compute different kind of solutions for the calibration problem

As the retail industry grows more popular, ABCD, a world-class electronic commerce (e-commerce) business, is increasingly building new Fulfillment Centers (FCs) to support this rapid demand growth. It is integral for ABCD to validate the installation quality and functionality of Material Handling Equipment (MHE) in these newly built FCs so operations can avoid errors. To achieve this objective, ABCD introduced the Installation and Operational Qualification (IOQ) process in late 2014. While the IOQ process reduces early operational failures, it does not completely eliminate them. Inadequate IOQ and tighter installation timelines are leading to degraded installation quality, resulting in operational issues and costs for ABCD. As the FC network continues to grow, there is a need to improve installation quality to reduce early operational issues and enhance the FC start-up experience.
This project is a part of the ABCD Operation Engineering teams' effort to improve the existing IOQ process and the FC start-up experience. This initiative consists of three main phases. The first phase - the research phase - is dedicated to understanding the current processes and problem statement. It also includes a study of available data sources to discover failure patterns across different FCs. The second phase involves developing analytical frameworks and machine-learning models to uncover the most problematic equipment in the FC. The third phase focuses on evaluating the effectiveness of the current IOQ process based on Phase 1 and 2 findings, and identifying opportunities to better the process. The thesis summarizes the outcomes from all of these phases. The project focuses on improving IOQ coverage, efficiently reprioritizing the testing schedule, introducing threshold metric for installation quality, and exploring predictive and preventative maintenance opportunities.
This thesis also includes recommendations for refining the data-gathering process to improve future model outcomes. The ultimate goal is to improve FC installation quality and enhance the IOQ process to eliminate start-up issues. The approach taken and the recommendations proposed seek to approximate the ideal state as closely as possible. Incremental adoption of these recommendations will help deliver better-installed FCs, reduce early operational issues, improve start-up experiences, and strengthen ABCD's infrastructure.

Approved for public release; distribution is unlimitedThis project reflects extensive research on the Defense Acquisition Workforce Improvement Act (DAWIA) certification process. Project participants analyzed the processes currently employed by the Department of Defense (DOD) for civilian Army acquisition Program Managers and compared these processes to other Services in relation to execution of the DAWIA certification process. Additionally, this project provides a comparative analysis of DAWIA compared to current DOD qualification initiatives. The intent of the project is to identify and provide recommendations for best of breed practices for maintaining a proficient workforce while preserving the integrity of the Army civilian Program Manager profession. While identification and recommendations for best of breed practices have been stated, the availability of qualification initiatives is either limited or emerging. As such, the researchers have identified future areas for further study. DAWIA addresses career path requirements in title 10, United States Code 1723 by stating that the Secretary of Defense acting through the Under Secretary of Defense for Acquisition, Technology and Logistics, shall establish requirements for the completion of course work and related on-the-job training and demonstration of qualifications in the critical acquisition-related duties and tasks of the career path. Workforce demographics are changing. The intent of the project is to examine current credentialing processes in place to maintain a proficient workforce and preserve the integrity of the profession. Prior research regarding the effectiveness of DAWIA exists. This project will leverage this available body of knowledge and will compare it to existing processes to identify more efficient mechanisms/certifications for qualifying civilian Army acquisition Program Managers..

Abstract: The quality of the Laser Metal Deposition process depends on several factors and components. One of them and also one of the most important is the powder jet. Regular monitoring of the different variables involved on the powder jet need to be performed in order to assure the demanded high stability and quality standards of the produced coating layers. This monitoring is done through process monitoring techniques, where the powder jet is illuminated from the side, by a laser line, and recorded by a coaxially aligned camera through the powder feed nozzle. Symmetry, geometry and position of different levels of the powder jet can be analyzed through relevant algorithms. They also provide calculations of the particle density distribution the recorded images. The spatial particle density distribution of the powder jet can be calculated by superimposing individual levels along the jet. The measurement and monitoring principle was successfully tested with various nozzles and powder properties, making it possible to fully characterize a powder jet.
A qualidade do processo de deposição de metais a laser depende de diversos fatores e componentes. Um dos componentes mais importantes é o fluxo de pó metálico. É necessário o monitoramento contínuo das diferentes variáveis e parâmetros que influenciam no fluxo de pó para se garantir os altos padrões de qualidade e estabilidade requeridos nas peças produzidas. Este monitoramento é realizado através de técnicas de controle de processos, onde o fluxo de pó metálico é iluminado lateralmente, por um laser de iluminação em formato de linha, e gravado por uma câmera coaxial ao bocal alimentador de pó. Simetria, geometria e posição de diferentes níveis do fluxo de pó podem ser analisados através de algoritmos relevantes. Tais algoritmos tornam possíveis também cálculos da distribuição das partículas no fluxo, através da sobreposição de imagens de todos os frames gravados no vídeo em cada nível do fluxo de pó. O processo de medição e análise foi testado com sucesso em diferentes bocais alimentadores de pó e com diferentes materiais e parâmetros do fluxo, tornando possível sua caracterização e qualificação.

ITC/USA 2010 Conference Proceedings / The Forty-Sixth Annual International Telemetering Conference and Technical Exhibition / October 25-28, 2010 / Town and Country Resort & Convention Center, San Diego, CaliforniaThe development and qualification of personnel and cargo aerial delivery parachute systems present unique challenges to the instrumentation and data analysis engineers. Some of the areas that must be addressed include: a) system must be low in cost, b) system often has to be operated on ranges that have limited telemetry or other range instrumentation and support (i.e. commercial skydiving centers), c) system is often rigged and operated by parachute support personnel and test jumpers rather than instrumentation engineers, and d) system must be able to be reconfigured in the field to support a variety of test card requirements during a typical test day, e) data must be available for review and the system be prepared for the next test within a few minutes of parachute recovery, and f) system must withstand ground impact velocities as high as 50 ft/sec (15.24 m/sec) without damage. This paper describes such a system as it is being used for the development and qualification testing of a number of parachute systems for sport skydiving, military personnel, as well as cargo parachute systems. This modular system has been developed as a result of previous experience in other parachute development and qualification projects to address the need for a flexible Data Acquisition System (DAS) system that meets the above requirements. This paper describes some of the tools used to meet these requirements.

Full textAbstract:
In the aviation industry, the use of software development tools is not as easily adopted as in other industries. Due to the catastrophic consequences of software errors in airborne systems, software development processes has rigorous requirements. One of these requirements is that a code standard must be followed. Code standards are used to exclude code constructions which could result in unwanted behaviours. The process of manually ensuring a specific code standard can be costly. This process could be automated by a tool for static code analysis, however, this requires a formal qualification. This thesis evaluates the process of qualifying a tool for static code analysis in accordance with the requirements of the major aviation authorities EASA and FAA. To describe the qualification process, a literature study was conducted. To further explain how an existing tool could be put through the qualification process, a case study of the existing tool Parasoft C/C++ test was conducted. The results of the literature study show what processes must be completed in order to qualify a static code analysis tool. Importantly, the study shows that no requirements are put on the development process of the tool. This was an important takeaway as it meant that an existing tool could be qualified without any additional data from the developer of the tool. The case study of Parasoft C/C++ test showed how the tool could be configured and verified to analyze code in accordance with a small set of code rules. Furthermore, three documents including qualification data were produced showing how the qualification process should be documented in order to communicate the process to an authority. The results of the thesis do not provide the full picture of how a tool could be qualified as the software, in which the tool is used, is considerations the are specific to the software the tool is used to develop still need to be taken into consideration. The thesis does, however, provide guidance on the majority of the applicable requirements. Future research could be done to provide the complete picture of the qualification process, as well as how the process would look like for other types of tools.Inom flygindustrin är användandet av olika programmeringsverktyg inte lika självklart som inom andra industrier. På grund av de katastrofala konsekvenser som fel i mjukvaran i ett flygplan kan resultera i finns det rigorösa krav på mjukvaruutvecklingsprocessen. Ett av dessa krav är att en viss kodstandard måste upprätthållas. Kodstandarder används för att exkludera vissa strukturer i kod som kan leda till oönskat beteende. Upprätthållandet av en viss kodstandard är en långdragen process att genomföra manuellt, och kan därför automatiseras med hjälp av ett statiskt kodanalysverktyg. För att kunna använda ett sådant verktyg behövs däremot en formell verktygskvalificering. I denna uppsats kommer kvalificeringsprocessen av ett verktyg för statisk kodanalys att evalueras enligt de krav som de två stora flygmyndigheterna EASA och FAA ställer. För att förklara processen av att kvalificera ett sådant verktyg gjordes en litteraturstudie följt av en fallstudie av det existerande verktyget Parasoft C/C++ test. Resultaten av litteraturstudien beskriver de olika processerna som måste genomföras för att kvalificera ett statiskt kodanalysverktyg. Noterbart är att resultaten visar att inga krav ställs på utvecklingsprocessen av verktyget själv. Detta betyder att ett existerande kommersiellt verktyg kan kvalificeras utan att verktygsutvecklarna själva behöver bidra med extra information. Fallstudien visade hur verktyget Parasoft C/C++ test kan konfigureras och verifieras att följa en viss kodstandard. Vidare resulterade fallstudien i utkast av de nödvändiga dokumenten som behöver produceras för att kommunicera kvalificeringsprocessen till en myndighet. De resultat som presenteras i denna uppsats är i sig inte tillräckliga för beskriva hela kvalificeringsprocessen. Ytterligare överväganden som är specifika till den mjukvaran som verktyget ska användas till att utveckla måste göras för att en komplett kvalificering ska kunna genomföras. Uppsatsen bidrar däremot med riktlinjer och vägledning av majoriteten av de processerna som behöver genomföras. Ytterligare forskning kan göras för att bidra med den kompletta bilden av verktygskvalificering av ett statiskt kodanalysverktyg, samt hur kvalificering kan göras av andra typer av verktyg.

La simulation numérique est largement utilisée pour évaluer les performances aérodynamiques des aéronefs ainsi qu'en optimisation de forme. Ainsi l'objectif de ces simulations est souvent le calcul de fonctions aérodynamiques. L'objet de cette thèse est d'étudier des méthodes d'adaptation de maillages basées sur la dérivée totale de ces fonctions par rapport aux coordonnées du maillage (notée dJ/dX). Celle-ci pouvant être calculée par la méthode adjointe discrète. La première partie de cette étude concerne l'application de méthodes d'adaptation de maillages appliquées à des écoulements de fluides parfaits. Le senseur qui détecte les zones de maillage à raffiner s'appuie sur la norme de cette dérivée pour adapter des maillages pour le calcul d'une fonction J. La seconde partie du travail est la construction et l'étude de critères plus fiables basés sur dJ/dX pour d'une part adapter des maillages et d'autre part estimer si un maillage est bien adapté ou non pour le calcul de la fonction J. De plus une méthode de remaillage plus efficace basée sur une EDP elliptique est aussi présentée. Cette nouvelle méthode est appliquée pour des écoulements bidimensionnels de fluides parfaits ainsi que pour un écoulement décrit par les équations RANS. La dernière partie de l'étude est consacrée à l'application de la méthode proposée à des cas tridimensionnels d'écoulement RANS sur des géométries d'intérêt industriel.

Ce travail de thèse porte sur les miels de Corse commercialisés sous l’AOC et l’AOP « Miel de Corse-Mele di Corsica » et classés en six catégories variétales : « printemps », « maquis de printemps », « miellat du maquis », « maquis d’été », « châtaigneraie » et « maquis d’automne ». Notre objectif principal était de caractériser la composition volatile des miels de Corse et de développer une approche interdisciplinaire en vue de compléter la caractérisation de ces productions par la recherche de nouveaux critères pour la qualification de l’origine botanique et/ou géographique. Les travaux ont donc consisté à croiser les données obtenues par la méthode conventionnelle basée sur les analyses polliniques, sensorielles et physico-chimiques avec celles issues de l’analyse chimique de la fraction volatile des miels.Dans une première partie, 195 miels de nectar ont été caractérisés au niveau pollinique, physico-chimique ainsi que par leurs compositions volatiles. L’analyse pollinique a permis de certifier l’origine Corse et de mettre en évidence les principales espèces nectarifères de chaque gamme variétale et/ou les associations végétales caractéristiques des miellées. L’analyse de la fraction volatile par MEPS, CPG et CPG/SM a conduit à l’identification des marqueurs chimiques des diverses variétés de miels, à savoir la 2-aminoacétophénone (« châtaigneraie ») ; le p-anisaldéhyde et le 4-n-propylanisole (« maquis de printemps ») ; l’isophorone et le 3,4,5-triméthylphénol (« maquis d’automne ») ; les isomères de lilac aldéhyde et du p-menthèn-9-al (« printemps typé clémentinier »). De plus, une étude interdisciplinaire (analyse mélissopalynologique, physico-chimique et fraction volatile) basée sur l’utilisation de traitements statistiques des données multifactorielles a été menée sur chacune des catégories variétales. Les résultats obtenus ont permis de mieux cerner l’origine botanique des miels « quasi-monofloraux » ; de proposer des hypothèses sur les autres apports nectarifères et/ou miellatifères dans les miels à taxon dominant de type sur-représenté (« châtaigneraie ») et normal (« maquis de printemps ») ; de déterminer les différentes contributions nectarifères dans les miels dont l’espèce dominante à un taxon de type sous-représenté (« printemps » et « maquis d’automne ») et dans ceux ayant une origine botanique complexe (« maquis d’été »).Dans la seconde partie de nos travaux, nous avons caractérisé la fraction volatile de 74 miels des gammes « miellat du maquis » et « miel de Corse ». L’analyse statistique de la variabilité chimique a permis de distinguer les miellats de Metcalfa par la teneur en 3-furaldéhyde. Par ailleurs, nous avons pu qualifier l’origine botanique des miels dit « génériques » (mélange « miel de miellat »/« miel de nectar »), notamment les apports significatifs de « châtaigneraie » (molécule marqueur : 2-aminoacétophénone) et/ou de « maquis de printemps » (p-anisaldéhyde et 4-n-propylanisol).Enfin, ces travaux ont permis de développer une approche innovante basée sur une approche multifactorielle (polliniques, physico-chimiques et volatils) afin de mieux qualifier la complexité des origines botaniques des miels de CorseThis thesis was focused on the Corsican honeys under the AOC and AOP appellation “Miel de Corse-Mele di Corsica”. The Corsican honey was classified in six varietal categories: “spring”, “spring maquis”, “honeydew”, “summer maquis”, “chestnut grove” and “automne maquis”. The aim of this work was to characterize the volatile composition of Corsica honey and to develop an interdisciplinary approach to complete the characterization of Corsican honey and the qualification of the botanical and/or geographical origin. In the first part, 195 nectar honeys were characterized by melissopalynological, physico-chemical and volatile analyses. Pollen analysis allowed the certification of Corsican origin and highlights the main nectariferous species and/or characteristic plant associations of each varietal range. Thus, the volatile analysis by SPME, GC and GC/MS allowed the identification of some chemical markers of honey, namely 2-aminoacetophenone (“chestnut grove”); p-anisaldehyde and 4-n-propylanisole (“spring maquis”); isophorone and 3,4,5-trimethylphenol (“automne maquis”); isomers of lilac aldehydes and p-menth-1-en-9-al (“spring clementine”).For each honey range, an interdisciplinary study was carried out by using statistical analysis of multifactorial data (melissopalynological, physico-chemical and volatile data). These results allowed us to identify the “monofloral” honey samples; to propose some hypotheses about the nectar and/or honeydew contribution in honeys with dominant over-represented (“chestnut grove”) and normal taxon (“spring maquis”); and to determine the role of different nectariferous and/or polleniferous species in honeys with underrepresented taxon (“spring” and “autumn maquis”) and those with complex botanical origin (“summer maquis”).In the second part of our work, the volatile fraction of 74 Corsican honeydews and blend honeys has also been investigated. Statistical analysis of the volatile composition has distinguished Metcalfa honeydew by a high abundance of 3-furaldehyde. Otherwise, the other honey samples were characterized by a high abundance of 2-aminoacetopheneone (marker of “chestnut grove” honey) and/or p-anisaldehyde and 4-n-propylanisol (characteristic compounds of “spring maquis" honey). These observations could be explained by the nectar contribution of Castanea sativa and/or Erica arborea in the honeydew samples. Finally, this work has allowed us to develop an innovative approach based on multifactorial approach (pollen analysis, physic-chemical parameters, volatile composition) to obtain discriminant information for the determination of the floral origin from Corsican honeys

Neff, Clayton. "Analysis of Printed Electronic Adhesion, Electrical, Mechanical, and Thermal Performance for Resilient Hybrid Electronics." Scholar Commons, 2018. https://scholarcommons.usf.edu/etd/7551.
Full textAbstract:
Today’s state of the art additive manufacturing (AM) systems have the ability to fabricate multi-material devices with novel capabilities that were previously constrained by traditional manufacturing. AM machines fuse or deposit material in an additive fashion only where necessary, thus unlocking advantages of mass customization, no part-specific tooling, near arbitrary geometric complexity, and reduced lead times and cost. The combination of conductive ink micro-dispensing AM process with hybrid manufacturing processes including: laser machining, CNC machining, and pick & place enables the fabrication of printed electronics. Printed electronics exploit the integration of AM with hybrid processes and allow embedded and/or conformal electronics systems to be fabricated, which overcomes previously limited multi-functionality, decreases the form factor, and enhances performance. However, AM processes are still emerging technologies and lack qualification and standardization, which limits widespread application, especially in harsh environments (i.e. defense and industrial sectors).
This dissertation explores three topics of electronics integration into AM that address the path toward qualification and standardization to evaluate the performance and repeatable fabrication of printed electronics for resilience when subjected to harsh environments. These topics include: (1) the effect of smoothing processes to improve the as-printed surface finish of AM components with mechanical and electrical characterization—which highlights the lack of qualification and standardization within AM printed electronics and paves the way for the remaining topics of the dissertation, (2) harsh environmental testing (i.e. mechanical shock, thermal cycling, die shear strength) and initiation of a foundation for qualification of printed electronic components to demonstrate survivability in harsh environments, and (3) the development of standardized methods to evaluate the adhesion of conductive inks while also analyzing the effect of surface treatments on the adhesive failure mode of conductive inks.
The first topic of this dissertation addresses the as-printed surface roughness from individually fusing lines in AM extrusion processes that create semi-continuous components. In this work, the impact of surface smoothing on mechanical properties and electrical performance was measured. For the mechanical study, surface roughness was decreased with vapor smoothing by 70% while maintaining dimensional accuracy and increasing the hermetic seal to overcome the inherent porosity. However, there was little impact on the mechanical properties. For the electrical study, a vapor smoothing and a thermal smoothing process reduced the surface roughness of the surfaces of extruded substrates by 90% and 80% while also reducing measured dissipative losses up to 24% and 40% at 7 GHz, respectively.
The second topic of this dissertation addresses the survivability of printed electronic components under harsh environmental conditions by adapting test methods and conducting preliminary evaluation of multi-material AM components for initializing qualification procedures. A few of the material sets show resilience to high G impacts up to 20,000 G’s and thermal cycling in extreme temperatures (-55 to 125ºC). It was also found that coefficient of thermal expansion matching is an important consideration for multi-material printed electronics and adhesion of the conductive ink is a prerequisite for antenna survivability in harsh environments.
The final topic of this dissertation addresses the development of semi-quantitative and quantitative measurements for standardizing adhesion testing of conductive inks while also evaluating the effect of surface treatments. Without standard adhesion measurements of conductive inks, comparisons between materials or references to application requirements cannot be determined and limit the adoption of printed electronics. The semi-quantitative method evolved from manual cross-hatch scratch testing by designing, printing, and testing a semi-automated tool, which was coined scratch adhesion tester (SAT). By cross-hatch scratch testing with a semi-automated device, the SAT bypasses the operator-to-operator variance and allows more repeatable and finer analysis/comparison across labs. Alternatively, single lap shear testing permits quantitative adhesion measurements by providing a numerical value of the nominal interfacial shear strength of a coating upon testing while also showing surface treatments can improve adhesion and alter the adhesive (i.e. the delamination) failure mode of conductive inks.

Cette thèse, dont le cadre général est l'optimisation, traite de problèmes d'optimisation non-lisse et de problèmes de théorie des jeux. Elle est constituée de quatre parties. Dans la première, nous présentons le contexte et l'introduction. Dans la deuxième partie, nous discutons quelques règles de calcul sous-différentiel dans des espaces généraux, et présentons notamment certaines formules plus fortes que l'état de l'art, autant dans le cas convexe que dans le cas non convexe. L'accent est mis sur les règles de calcul et conditions d'optimalité approchées et "fuzzy", pour lesquelles aucune condition de qualification n'est requise. Dans la troisième partie, nous considérons des jeux bi-niveaux à plusieurs meneurs et plusieurs suiveurs. Après quelques résultats d'existence dans le cas d'un seul meneur optimiste et dans le cas de plusieurs meneurs, nous étendons des résultats existants concernant la relation entre le problème bi-niveau original et sa reformulation obtenue grâce au remplacement des problèmes des suiveurs par la concaténation de leurs conditions d'optimalité (KKT). Finalement, dans la quatrième partie, nous abordons quelques problèmes de quasi-équilibre, qui sont une généralisation des problèmes d'équilibre de Nash et des inégalités quasi-variationnelles. Nous prouvons ainsi de nouveaux résultats d'existence qui permettent de relâcher les hypothèses standardThis thesis is within the framework of optimization and deals with nonsmooth optimization and with some problems of game theory. It is divided into four parts. In the first introductory part, we give the context and some preliminary results. In the second part we discuss about subdifferential calculus rules in general spaces providing of some improved formulas in both the convex and the non-convex cases. Here the focus is on approximate or fuzzy calculus rules and optimality conditions, for which no qualification conditions are required. In the third part, we discuss about the so-called Multi-Leader-Follower Games. We give an existence result for the case of a single optimistic leader and multiple followers, and extend some results concerning the relation between the original problem with the reformulation obtained by replacing the followers' problem by the concatenation of their KKT conditions. Finally, in the fourth part we study quasi-equilibrium problems which are a general formulation for studying Nash equilibrium problems and quasi-variational inequalities. We provide some new existence results that relax some of the standard hypotheses

Discussions regarding Gender and Sexuality have been receiving more attention in the society, being reflected in a common manner in educational and training environments. With the objective of comprehending how it is being constructed into the teachers‟ initial qualification process, a research was developed in a public university campus, with five licentiate courses: Biological Sciences, Nursing, Languages, Mathematics and Pedagogy. Through a qualitative approach, the objective was to analyze in what manner these courses are developing the Gender and Sexuality issues in the teachers‟ initial qualification process. Pedagogical projects of eighteen licentiate courses, from five university campi, were analyzed. Soon after, we deepened the discussions for a campus of this university and we conducted semi-structured interviews with the students of the last year, of five courses of this campus. Both for research development and for data analysis, the support of the Discourse Analysis was used. The investigation results show that the issue is present in the pedagogical projects of five courses, however, in three of them the issue was inserted only after the law Resolução CNE/CP 02/2015 determined the introduction of the subject into the curriculum of initial qualification courses. Data presented by students indicate that discussions about the issue happen in a specific situation, because of a determined professor or during events. It is also indicated that biology-oriented courses like Biological Sciences and Nursing address the theme with a biological-anatomic view, whereas in Human Science courses like Languages and Pedagogy and Exact Sciences like Mathematics the addressing is wider in their PPs – actions are specific and developed by determined professors.
As discussões acerca das temáticas de Gênero e Sexualidade vêm tomando cada vez mais espaço em nossa sociedade, sendo refletidas de maneira corriqueira nos ambientes educacionais e de formação. A fim de compreender como isso está ocorrendo no processo de formação inicial de professoras/es, desenvolvemos essa pesquisa em um campus de uma universidade pública no Estado do Paraná, com cinco cursos em Licenciatura, sendo eles Ciências Biológicas, Enfermagem, Letras, Matemática e Pedagogia. Por meio de uma abordagem qualitativa, objetivamos compreender como esses cursos estão desenvolvendo as temáticas de Gênero e Sexualidade na formação inicial de professoras/es. Para isso, coletamos e analisamos, em um primeiro momento, os Projetos Pedagógicos dos 18 cursos em Licenciatura, distribuídos em cinco campi da universidade. Após esse primeiro momento, aprofundamos as discussões para um campus dessa universidade e realizamos entrevistas semiestruturadas com as/o alunas/o do último ano, de cinco cursos desse campus. Tanto para o desenvolvimento da pesquisa quanto para as análises dos dados buscou-se o apoio metodológico da Análise de Discurso. Os resultados da investigação aqui proposta indicam que as temáticas estão presentes nos Projetos pedagógicos dos cinco cursos, entretanto, em três deles só aconteceu a inserção das temáticas após a Resolução CNE/CP nº 02/2015, que determinou a incorporação das temáticas de Gênero e Sexualidade nos currículos dos cursos de formação inicial, continuada e segunda graduação. Os dados apresentados pelas/os alunas/os indicam que as discussões a respeito das temáticas em sala de aula ocorrem de modo pontual, por um determinado professor, ou por meio de eventos. Apontam também que, principalmente, os cursos voltados para as Ciências Biológicas e da Saúde (Ciências Biológicas e Enfermagem) abordam as temáticas por um viés principalmente biológico-anatômico, enquanto os cursos voltados para as Ciências Humanas (Letras e Pedagogia) e Ciências Exatas (Matemática), por mais que indiquem abordagens mais amplas em seus PPs, as ações são pontuais e desenvolvidas por determinadas/os professoras/es.

Full textAbstract:
Dans l’industrie de l’avionique, les Générateurs Automatiques de Code (GAC) sont de plus en plus utilisés pour produire des parties du logiciel embarqué. Puisque le code généré fait partie d’un logiciel critique, les standards de sûreté exigent une vérification approfondie du GAC: la qualification. Dans cette thèse en collaboration avec AdaCore, nous cherchons à réduire le coût des activités de test par des méthodes automatiques et efficaces.La première partie de la thèse aborde le sujet du test unitaire qui assure une exhaustivité élevée mais qui est difficile à réaliser pour les GACs. Nous proposons alors une méthode qui garantit le même niveau d’exhaustivité en n’utilisant que des tests d’intégration de mise en œuvre plus facile. Nous proposons tout d’abord une formalisation du langage ATL de définition du GAC dans la théorie des Transformations Algébriques de Graphes. Nous définissons ensuite une traduction de postconditions exprimant l’exhaustivité du test unitaire en des préconditions équivalentes qui permettent à terme de produire des tests d’intégration assurant le même niveau d’exhaustivité. Enfin, nous proposons d’optimiser l’algorithme complexe de notre analyse à l’aide de stratégies de simplification dont nous mesurons expérimentalement l’efficacité.La seconde partie du travail concerne les oracles de tests du GAC, c’est à dire le moyen de valider le code généré par le GAC lors d’un test. Nous proposons un langage de spécification de contraintes textuelles capables d’attester automatiquement de la validité du code généré. Cette approche est déployée expérimentalement à AdaCore pour le projet QGen, un générateur de code Ada/C à partir de Simulink®In the avionics industry, Automatic Code Generators (ACG) are increasingly used to produce parts of the embedded software. Since the generated code is part of critical software, safety standards require a thorough verification of the ACG called qualification. In this thesis in collaboration with AdaCore, we seek to reduce the cost of testing activities by automatic and effective methods.The first part of the thesis addresses the topic of unit testing which ensures exhaustiveness but is difficult to achieve for ACGs. We propose a method that guarantees the same level of exhaustiveness by using only integration tests which are easier to carry out. First, we propose a formalization of the ATL language in which the ACG is defined in the Algebraic Graph Transformation theory. We then define a translation of postconditions expressing the exhaustiveness of unit testing into equivalent preconditions that ultimately support the production of integration tests providing the same level of exhaustiveness. Finally, we propose to optimize the complex algorithm of our analysis using simplification strategies that we assess experimentally.The second part of the work addresses the oracles of ACG tests, i.e. the means of validating the code generated by the ACG during a test. We propose a language for the specification of textual constraints able to automatically check the validity of the generated code. This approach is experimentally deployed at AdaCore for a Simulink® to Ada/C ACG called QGen

Full textAbstract:
The economic growth in the tourism industry is changing the structure of labour markets, increasing the level of competitiveness and thereby creating a need for improved labour productivity and a more flexible workforce. Education and the creation of employment are among the key priorities of the South African government. This process can be successful only if companies raise performance and productivity standards through the enhancement and development of skills. To succeed in the rebuilding process, it is imperative that the various stakeholders interact to establish the composition of the relevant skills and qualifications required. Consequently, the growth of job opportunities in the tourism sector has uncovered various challenges, including gaps in the areas of education, training and development. These gaps have resulted in low levels of productivity and are currently creating unsatisfied expectations for students and job providers. Hence, it is a priority of government to develop quality Learnerships and Internships in South Africa to improve skills and the qualifications of the tourism workforce. Employers are increasingly conscious of the value for money from their investments in training and are demanding that training be more deliberately aligned with the strategic needs of their organisations. However, the tourism industry is still complaining that learners are not adequately prepared for the workplace and the learners believe that they have sufficient knowledge to meet the needs of the industry.
The purpose of this research was to analyse the skills expectations of learners versus employers: the case of the Culture, Arts, Tourism, Hospitality and Sport SETA (CATHSSETA). To achieve this aim, the following objectives were set: to analyse literature concerning human resource management with the main focus falling on training, to contextualise the current tourism education environment in South Africa, to compare the differences in skills expectations between learners and employers in the tourism industry and, lastly, to draw conclusions and make recommendations regarding the skills expectations in tourism education. This was achieved by conducting quantitative research by means of a structured questionnaire that was distributed to 202 employers and 1023 learners on the CATHSSETA database. The questionnaires were linked and captured on an online program named SurveyMonkey. The application of SPSS, descriptive statistics, Factor Analysis, Confirmatory Factor Analysis, ANOVA and t-tests resulted in indicating various significant differences between skills expected by employers and skills presented by learners.
These statistical analysis methods were used to demonstrate the gaps between the skills expectation of the role players. It was surprising to find that significant differences existed for most skills with the biggest gaps on self-reliance and people skills. The employers’ survey reflected that a priority for employers is customer orientation and learners’ willingness to learn. In all instances, employers expected learners to be better skilled than was the actual case. The results suggest that the learners are unable to adhere to the current demands of the industry. It was also found that learners rated their own skills much higher than the perception of employers.
The results of this study can be used to assist CATHSSETA in improving their current training programmes to ensure they meet the needs of the broader tourism industry. It can also be used as a guideline for any training institution for improving the current tourism training programmes. This will contribute to the overall quality and sustainability of the tourism industry.Thesis (MCom (Tourism Management))--North-West University, Potchefstroom Campus, 2013.

A presente investigação assume como objeto de estudo o referencial de competências do Exército Português, numa investigação que tentará perceber como este se articula com o Sistema Nacional de Qualificações (SNQ), e como enquadramento normativo da Agência Nacional da Qualificação (ANQEP) I.P., comparando-o com outros modelos de referencial de competências, de natureza militar, de exércitos si-milares: o Ejército de Tierra de España e o Ejército de Chile, bem como, a organização da formação na North Atlantic Treaty Organization (NATO). Por fim, com base no estudo realizado e na comparação esta-belecida com os sistemas internacionais equivalentes, apresenta uma proposta de melhoria ao modelo de referencial de competências do Exército Português.
No plano teórico abordam-se os conceitos de educação e de formação, assim como a sua relação com o meio profissional. Carateriza-se o conceito de competência, em todas as suas dimensões, assim como, a avaliação de competências e a gestão por competências. Aborda-se, igualmente, o conceito e o propósito do referencial de competências.
A investigação baseou-se num estudo comparativo de casos múltiplos, no qual tentámos compre-ender os diferentes contextos da formação nos países e organização selecionados.
Concluiu-se que o referencial de competências traduz um conjunto de orientações pedagógicas, que definem as trajetórias de desenvolvimento do formando, baseando-se em aprendizagens críticas, essen-ciais à progressão do conhecimento. Observou-se que o referencial de competências, pela relevância que assume na qualificação dos quadros, deve ser elaborado por equipas multidisciplinares especializadas, que permitam, na sua elaboração, desenvolver uma antevisão do que vai ser o desempenho do cargo/fun-ção num futuro próximo, pretendendo obter um militar bem formado, dotado de elevados padrões de eficácia e de eficiência.
Os resultados apresentados permitiram igualmente, elaborar uma proposta de atualização ao refe-rencial de curso do Exército Português, assim como, uma proposta de desenvolvimento de uma plata-forma de apoio à sua conceção; Abstract:
Title: The Competence Referential in the context of military training: a comparative study of the cases of the Portuguese, Spanish, Ejército de Chilean and NATO Army.
The present investigation approaches the competence referential of the Portuguese Army. It con-sists of understanding how it articulates with the National Qualifications System (SNQ), describing it and placing it within the competences referential of the SNQ and the National Qualification Agency (ANQEP) I.P. It is compared with other models of competence referential, of military nature, of similar armies serv-ing as sample the Armies of Spain, Chile and the North Atlantic Treaty Organization (NATO). Finally, based on the study carried out and the comparison established with the equivalent international systems, it presents a proposal to improve the Portuguese Army's competence referential model.
Theoretically, it approaches the concepts of education and training, as well as its relationship with the professional environment. The concept of competence is characterized in all its dimensions, as well as the assessment of competencies and management by competencies. It also addresses the concept and purpose of the competence referential.
The investigation was based on a comparative study of multiple cases, in which we tried to under-stand the different contexts of training in the selected countries and organization.
It was concluded that the competence referential translates a set of pedagogical guidelines, which define the trainee's development trajectories, based on critical learning, essential to the progression of knowledge. It was observed that the competences referential, due to the production it assumes in the qualification of the staff, must be developed by specialized multidisciplinary teams, which need, in their preparation, to develop a preview of what the performance of the position will be in the near future, aiming to obtain a well-trained military, endowed with high standards of effectiveness and efficiency.
The results presented also made it possible to elaborate a proposal to update the Portuguese Army course referential, as well as a proposal to develop a platform to support its conception.

Dans cette thèse, nous avons étudié les méthodes de régularisation pour la résolution numérique de problèmes avec équilibres. Dans une première partie, nous nous sommes intéressés aux problèmes de complémentarité au travers de deux applications : les équations en valeur absolue et les problèmes de parcimonie. Dans une seconde partie, nous avons étudié les problèmes d'optimisation sous contraintes de .complémentarité. Après avoir définies des conditions d'optimalité pour ces problèmes nous avons proposé une nouvelle méthode de régularisation appelée méthode des papillons. A partir d'une étude de la résolution des sous-problèmes de la régularisation nous avons défini un algorithme avec des propriétés de convergence forte. Tout au long de ce manuscrit nous nous sommes concentrés sur les propriétés théoriques des algorithmes ainsi que sur leurs applications numériques. La dernière partie de ce document est consacrée aux résultats numériques des méthodes de régularisationIn this thesis, we studied the regularization methods for the numerical resolution of problems with equilibria. In the first part, we focused on the complementarity problems through two applications that are the absolute value equation and the sparse optimization problem. In the second part, we concentrated on optimization problems with complementarity constraints. After studying the optimality conditions of this problem, we proposed a new regularization method, so-called butterfly relaxation. Then, based on an analysis of the regularized sub-problems we defined an algorithm with strong convergence property. Throughout the manuscript, we concentrated on the theoretical properties of the algorithms as well as their numerical applications. In the last part of this document, we presented numerical results using the regularization methods for the mathematical programs with complementarity constraints

Full textAbstract:
This thesis reports on an evaluation of competence-based vocational education practice in Scotland, with particular reference to Scottish Vocational Qualifications. The research was undertaken between 1996-1999 and included a national survey of higher level SVQ students in Scotland, an analysis of national database on N/SVQs and case study research with providers and students. It was found that participation in the 'new vocationalism' was highly gender patterned, had little impact on education and training targets and was skewed in favour of particular awards and occupational groups. The criterion-based assessment methodology proved more time-consuming for the students than the staff, with the emphasis on producing paper-based portfolios of evidence. A particular concern emerging from the research was the superficial nature of learning taking place on competence-based vocational education programmes and the role of the Local Enterprise Companies. These findings are discussed in the context of the growth in 'outcome-based' approaches to education adopted by policy makers in Scotland. It is argued that the narrow instrumentalist employer-led standards used to underpin education practice are ill-suited to developing a highly skilled professional workforce for the next century.

Resumo: A pesquisa tem como objetivo geral fazer a análise da política pública de qualificação profissional de educandos da Educação de Jovens e Adultos - EJA, por meio do projeto EJA Profissões, nos cursos do segundo segmento dessa modalidade no âmbito da Secretaria Municipal de Educação no município de Campinas/SP. O referencial teórico-metodológico fundamenta-se na abordagem do ciclo de políticas, formulada por Stephen Ball, uma vez que essa abordagem compreende a análise da trajetória de políticas públicas educacionais, da sua formulação à implementação, por meio do estudo dos contextos de influência, contexto do texto e contexto da prática. A pesquisa é qualitativa e se baseou em um estudo de caso, realizado em duas das três escolas indicadas pela Secretaria Municipal de Educação de Campinas como unidades piloto para a implementação dessa política pública. Pretende-se dar maior visibilidade ao processo de implementação dessa política e, com isso, conhecer as questões que a levaram a fazer parte da agenda política, seus formuladores, seus implementadores e, por fim, as possíveis relações entre os objetivos da medida e sua efetiva implementação.
Abstract: The research aims to make the analysis of public policy on students' professional qualifications of Youth People and Adults - EJA, through the project "EJA Profissões", in the second segment courses of this modality of education, within the scope of the City Department of Education in Campinas/SP. The theoretical and methodological approach is based on the Stephen Ball's 'policy cycle'. This approach includes the analysis of the trajectory of educational public policies, from their formulation to their implementation, through the study of the influence contexts, the text context and the practice context. The research is qualitative and it is based on a case study conducted in two of the three schools listed by the City Department of Education of Campinas as pilot units for the implementation of this public policy. The expectation of the research is to give a broader visibility to the process of implementation of this public policy. From there, understand the issues that led it to the political agenda, its formulators and implementers, and also the possible relationships between the objectives of this process and its effective implementation.

EXECUTIVE SUMMARY: This project was completed by the Resource Management Solutions Group, on behalf of the Commander, Helicopter Sea Combat Wing Atlantic (CHSCWL), and facilitated through the Naval Postgraduate School Executive MBA program. The purpose is to collect and analyze data pertaining to current scheduling challenges for helicopter pilot deck landing qualifications (DLQs). The data is used to compare three potential courses of action (COAs) and provide a recommendation for a COA to pursue based on the lowest cost alternative that meets operational requirements. This study focuses on the MH-60S helicopter squadrons assigned to CHSCWL. Sortie data was gathered from the Helicopter Sea Combat Squadron Two and interview data collected from various Norfolk-based MH-60S squadrons was incorporated as well. This project focuses primarily on two areas of interest: alleviating the DLQ scheduling challenges experienced between CHSCWL and the United States Second Fleet (C2F) and finding the most cost effective solution that also meets the operational requirements of the Fleet Replacement Squadron (FRS), Fleet squadrons, and ships assigned to C2F. Our analysis examines three possible courses of action: COA 1: Continue to conduct DLQ events using the current process of utilizing fleet ships already underway for training COA 2: Dedicate a C2F duty ship with sole responsibility of conducting DLQ events for a specified period of time during its duty rotation COA 3: Award a civilian company a contract to utilize a Helicopter Landing Trainer (HLT) to conduct DLQ events in the Chesapeake Bay or James River The results show all three COAs are capable of meeting DLQ requests; however, COA 3 provides the best solution for two main reasons. A Helicopter Landing Trainer allows for the highest level of operational readiness and minimizes the scheduling difficulties that have been experienced with DLQ requirements. Additionally, using a cost comparison, COA 3 proves to be the least costly alternative. The decision to utilize an HLT would potentially yield an annual savings of nearly $1.0 million.

Entretanto, normalmente, não é citada a especificação em termos do tempo necessário para alcançar estes valores, devido ao tempo de resposta do instrumento. Esta dissertação de mestrado tem como objetivo desenvolver uma metodologia teórico-experimental para avaliar o desempenho do transdutor em condições transientes, indicando alguns valores típicos para medidores comerciais, e sua resposta na medição de pH, a partir do modelo testado em uma reação experimental, sendo o mesmo simulado em outras reações químicas para diferentes velocidades de reação.Através deste modelo qualificado, foram avaliados os erros devidos às respostas permanentes e transientes, mostrando em que condições o medidor de pH pode ser usado, a partir da comparação entre valores de pH real e valores de pH registrados pelo medidor, levando em consideração a temperatura e o tempo de reação.
The electrochemical analysers available in the market assert trustworthy values applicable in a specific uncertainty range, which varies depending on the unit`s model.Nevertheless, rarely is given any information on the time necessary to reach these values, which depend on the answer of the instrument. This Master`s dissertation aims to develop an experimental theoretical methodology to evaluate the performance of the transducer in transient conditions, and obtain some typical values for commercial analysers, and its answer in the pH measurements in simulated chemical reactions in various reaction velocities. Through the qualified model, the errors due to the permanent and transient answers were evaluated, establishing the conditions pH electronic units can be used, in a pre-set controlled error, from the comparison between real pH values and displayed pH values in the analysers, considering the temperature and the reaction time.

Full textAbstract:
This thesis is based on a research study that examined aspects of the implementation of the Welsh Baccalaureate Advanced Diploma. Particular emphasis is given to the compulsory integration of Essential Skills Wales into the upper-secondary curriculum and the extent to which this contributes towards fulfilling the policy promise to offer a common learning Core to all students irrespective of their programmes of study and site of learning. By drawing insights from Bernstein’s sociology, I provide a principled analysis of the challenge of integrating these generic forms of everyday knowledge and make empirically visible their theoretically identified misrecognition and complexity. Based on a comparative twin case study (i.e. Communication and Application of Number) carried out across six considerably different educational sites, my findings uncover the peculiarities and challenges of pacing and evaluating the teaching and learning involved in Essential Skills Wales, and also point to administrative constraints, individual and institutional commitment to the demonstration of knowledge acquisition (i.e. certification). Students’ choices of subjects and qualifications (i.e. A level and BTECs), and the prioritisation of these, point to the power Higher Education institutions have to influence upper-secondary education. This is a separate strand of empirical work in the study, through which we see the possibility of a shift towards vocational qualifications under the overarching Welsh Baccalaureate Advanced Diploma. Based on this indication, I put forward the suggestion that, although the Welsh Baccalaureate is a notable attempt to change the relationship between specialised and everyday knowledge, and between academic (general) and vocational qualifications, it remains the latest form of the applied studies track in a tripartite upper-secondary system. To conclude, the Welsh Baccalaureate may contribute to the creation of a more subtle system of pedagogic differentiation, but upper-secondary education in Wales and the rest of the UK will most likely continue to be highly specialised, competitive and stratified.

Full textAbstract:
This thesis explores the reform of 14+ qualifications in England and Wales over the last decade.' I argue that the qualifications system has moved through different phases of development and is emerging, in the late 1990s, as a 'linked system'. Using a historical approach to periodising qualifications change, I argue that the 14+ qualifications system has moved through six phases of national policy development since the late 1970s - a precursor two-track phase, a prevocational phase, dualist strategy phase, a triple-track phase, a review phase and now a linkages phase. I go on to argue that these policy phases should also be viewed as constituting three 'overlapping eras' - the New Vocationalism, formally divided systems and unification. The concept of overlapping eras shows how there can be a co-existence of different policy initiatives and debates. The thesis goes on to argue that the dynamics of change, which move policy between phases and eras, are caused by external factors, internal system factors (reactions to of previous reforms and system weaknesses and the knock-on effect of reforms in other parts of the education and training system) and through the role of ideological interpretation. Using this approach to policy change, I argue that as the education and training system expands, internal system factors become more important than external factors as determinants of change. I conclude the thesis with three arguments: first, that the English qualifications system is currently poised between a flexible multi-track system and a unified system; second, there is a strong momentum building within the education and training system to move further towards unification; and third, there is a debate taking place about the type of unification strategy most appropriate to the English context and which can respond to the growing policy emphasis on lifelong learning.

The purpose of this study was to provide a descriptive analysis comparing highly qualified and non-highly qualified special education teachers in the 2011-12 Schools and Staffing Survey. It examined how the qualifications of special education teachers varied among K-12 public schools according to the urbanicity of the school and the proportion of students in poverty within a school. Variables included those related to teacher qualifications, demographic characteristics, and school characteristics.
The findings demonstrated that there were differences in the demographic characteristics of highly qualified and non-highly qualified special education teachers. There were no statistically significant differences found for urbanicity alone. There were statistically significant differences found for poverty levels. Statistically significant differences were also found for both highly qualified and non-highly qualified special education teachers when poverty quartiles were analyzed by urbanity locales.
The findings emphasize the need to provide targeted interventions to promote, retain, and supply all schools with qualified special education teachers. The findings also indicate there is an unequal distribution of highly qualified special education teachers within identified poverty levels and urbanicity.PHD

Full textAbstract:
British government introduced a new General National Vocational Qualification (GNVQ) as an alternative to the A-level qualification in response to a low skilled workforce. Although these qualifications are promoted as equivalent to the A-levels, vocational qualifications are considered second best, causing an academic/vocational divide. Some researchers have analyzed the internal and external nature of the qualifications. However, little empirical evidence directly compares the two. This study focused on analyzing the two equivalent qualifications represented in the national framework.The study used common areas of the A-level Physical Education and the GNVQ Leisure and Tourism curriculum to construct an examination paper consisting of an equal number of A-level and GNVQ-style questions. Two groups of A-level and GNVQ students were randomly selected from Godalming Sixth Form College to take part in the examination, and the performance scores were analyzed. Findings suggest no significant difference in performance scores, t(28) = 0.08, p = 0.94, supporting the need for further research. These results may assist in closing the academic/vocational divide. In turn, this may lead to more opportunities in industry and in universities for those achieving the GNVQ. In order to achieve true parity of esteem between the qualifications, reform needs to focus on the internal structure of the qualifications by combining the two curricular into one course represented as one qualification rather than organising the separate qualifications in a hierarchical external framework that still promotes the academic/vocational divide within the framework.

La deuxième approche porte sur l'interaction chimique de la phase aérosol sur la phase gazeuse (un thème émergent en chimie de l'atmosphère) et montre que les mesures sur la phase aérosol sont indispensables pendant les épisodes de fortes pollutions, en plus de leur intérêt propre (notamment pour la santé). Cette étude illustre ainsi deux thèmes essentiels de la chimie (et donc de la pollution) atmosphérique. " (Résumé auteur)

Full textAbstract:
This dissertation aims to examine the development and implementation of competence-based National Vocational Qualifications (NVQs) in three service industries: hospitality, retail and travel. The literature review traces the history of vocational education and training in the UK, the management of curriculum innovation and the evolution of competence-based education and training (CBET). In the second part of the thesis attention is focused on the establishment of the National Council for Vocational Qualifications (NCVQ). The main objective was to compare and contrast the experiences of those involved in the NVQ initiative across the three industries, to identify the common issues. The primary research was based on the findings of 45 in-depth interviews with individuals occupying a range of positions in different sectors of the hospitality, retail and travel industries. Generally, the analysis identified that the NVQ initiative has encountered significant problems. Originally, NVQs were intended to be designed by industry and only awarded as a result of assessment in the workplace. Over the past ten years this objective has proved to be unrealisable, although there have been many attempts, by the Government, to 'create success'. The comparison of the three industries revealed that the greatest success has been achieved in the retail industry with the least progress being made in the travel industry. The findings highlight the significance of the employment and training characteristics of each industry. One major conclusion which is drawn is that each industry should have been appraised before being subjected to rigid policies concerning the introduction of NVQs. Overall the thesis presents a case study of national confusion in the UK system of vocational education and training. The Government has invested significant sums of money in a change programme, which is based on a poor model and which nobody seems to really understand.

Celle-ci s'appuie d'une part, sur un travail de création en partenariat avec le Ministère de l'éducation nationale, via les branches professionnelles, de diplômes correspondant aux métiers de CGEA et d'autre part, sur un Centre de formation des apprentis dédié au groupe qui accueille chaque année 350 jeunes depuis 1994. À l'issue de la formation, le groupe CGEA s'engage à embaucher ces jeunes en Contrat à durée indéterminée et à temps plein à partir du moment où ils réussissent les examens préparés. Cette thèse en convention CIFRE analyse comment, pour un grand groupe de service, la mise en forme d'une offre de formation adaptée à ses besoins permet, par un travail sur les qualifications, d'améliorer la qualité de service. Pour cerner cette problématique générale, cette thèse cherche à répondre successivement à trois questions : 1) pourquoi un groupe a décidé de créer un dispositif appuyé sur des diplômes nationaux et donc permettant le développement de comportements opportunistes de la part des jeunes en formation ? 2) quelles qont les conséquences de la mise en oeuvre d'un tel appareil de formation sur les jeunes qui traversent ce dispositif au niveau de leurs qualifications mais aussi de leurs identités professionnelles ? 3) comment l'introduction de ces nouvelles qualifications contribue à recomposer les organisations du trvail, la structuration des carrières notamment et la politique de formation continue ?

Full textAbstract:
The increasing complexity of embedded systems development is becoming difficult to handle with development environments based on disjoint engineering tools. Support for interactions between various engineering tools, especially through automated means, has therefore received an increased amount of attention during the last few years. The subsequent increase in the amount of tool integration is leading to an increased impact of tool integration on non-functional properties of development efforts, development environments and end products. At the same time there is a lack of methods and tools for analysing the relationship between these properties and tool integration. To establish a foundation for analysing this generic relationship, the specific relationship between tool integration and the safety of end products is analysed in this thesis. A survey was conducted to analyze the State of the Art of tool integration as related to safety. This survey specifically identified the lack of an efficient handling of tool integration by modern safety standards as an important concern. In relation to this survey, three theories were identified as of specific importance. These are the school of thought known as Systems Thinking, the Systems-Theoretic Accident Model and Processes (STAMP) causality model and the System-Theoretic Process Analysis (STPA) hazard analysis technique. Building on these theories, this thesis provides original contributions intended to (1) describe concepts and models related to tool integration and safety (the first and second contribution), (2) link tool integration to safety in a way that reduces complexity during analysis (the third contribution) and (3) propose how to interpret and make use of the implications of the presented theories and the first three contributions (the fourth and fifth contribution). • The first contribution is a new conceptual model of a development effort that emphasizes tool integration. • The second contribution is a new reference model for tool integration in highly heterogeneous environments. • The third contribution consists of nine safety-related tool chain properties, i.e. properties of tool chains that could mitigate at least part of the risks introduced by tool integration. • The fourth contribution is a proposition on how to identify safety implications due to a high level of automation of tool integration. • The fifth contribution is a proposition for a new software tool qualification process.

Mestrado em Gestão de Recursos HumanosA vantagem competitiva organizacional depende grandemente da capacidade de utilizar os recursos humanos. Como resultado, deve ser dada a devida importância às competências, qualificações e comportamentos desses recursos. O sucesso organizacional depende desse alinhamento, e de uma estratégia que envolva o mundo operacional e o mundo individual. Como foco principal, este relatório visa a criação de um projeto-piloto de Avaliação de Desempenho para o Departamento Logístico do Grupo Efcis, através da análise dos dados recolhidos do instrumento de Análise e Descrição de Funções, criado para esse efeito. No entanto, por via do mesmo instrumento, foi possível a obtenção de dados relevantes acerca de outros departamentos. Com base numa amostra de 33 participantes, conseguiram-se obter resultados consideráveis sobre as percepções das competências e da importância do trabalho para os colaboradores analisados, dando uma ideia do panorama geral dos departamentos.
Organizational competitive advantage depends largely on the ability to activate and use their human resources. As a result, it is of great importance to consider the competences, qualifications and behaviors of those resources. Organizational success depends on that alignment and on a strategy, which involves both worlds, operational and individual. As a major focus, this report aims the construction of a Pilot Project of Performance Appraisal oriented to the Logistics’ Department of Grupo Efcis. This was possible through the analysis of the data collected from the Job Analysis’ questionnaire created for that purpose. However, that same questionnaire allowed the collection of relevant data from other departments. Based on a sample of 33 participants, it was possible to obtain some relevant results in what concerns to the perceptions of the competences and the importance given to work by the analyzed workers, which gives us a general idea of the departments.

Doutoramento em MatemáticaThis thesis is devoted to the study of regularity in semidefinite programming (SDP), an important area of convex optimization with a wide range of applications. The duality theory, optimality conditions and methods for SDP rely on certain assumptions of regularity that are not always satisfied. Absence of regularity, i.e., nonregularity, may affect the characterization of optimality of solutions and SDP solvers may run into numerical difficulties, leading to unreliable results. There exist different notions associated to regularity. In this thesis, we study in particular, well-posedness, good behaviour and constraint qualifications (CQs), as well as relations among them. A widely used CQ in SDP is the Slater condition. This condition guarantees that the first order necessary optimality conditions in the Karush-Kuhn-Tucker formulation are satisfied. Current SDP solvers do not check if a problem satisfies the Slater condition, but work assuming its fulfilment. We develop and implement in MATLAB numerical procedures to verify if a given SDP problem is regular in terms of the Slater condition and to determine the irregularity degree in the case of nonregularity. Numerical experiments presented in this work show that the proposed procedures are quite effcient and confirm the obtained conclusions about the relationship between the Slater condition and other regularity notions. Other contribution of the thesis consists in the development and MATLAB implementation of an algorithm for generating nonregular SDP problems with a desired irregularity degree. The database of nonregular problems constructed using this generator is publicly available and can be used for testing new SDP methods and solvers. Another contribution of this thesis is concerned with an SDP application to data analysis. We consider a nonlinear SDP model and linear SDP relaxations for clustering problems and study their regularity. We show that the nonlinear SDP model is nonregular, while its relaxations are regular. We suggest a SDP-based algorithm for solving clustering and dimensionality reduction problems and implement it in R. Numerical tests on various real-life data sets confirm the fastness and efficiency of this numerical procedure.
Esta tese _e dedicada ao estudo de regularidade em programação semidefinida (SDP - semidefinite programming), uma importante área da optimização convexa com uma vasta gama de aplicações. A teoria de dualidade, condições de optimalidade e métodos para SDP assentam em certos pressupostos de regularidade que nem sempre são satisfeitos. A ausência de regularidade, isto é, não regularidade, pode afetar a caracterização da optimalidade de soluções e os solvers podem apresentar dificuldades numéricas, conduzindo a resultados pouco fiáveis. Existem diferentes noções associadas a regularidade. Nesta tese, estudamos em particular, os conceitos de problemas bem-postos, bem comportados e condições de qualificação de restrições (CQ - constraint qualifications), bem como as relações entre eles. Uma das CQs mais utilizadas em SDP é a condição de Slater. Esta condição garante que as condições de optimalidade de primeira ordem, conhecidas como condições de Karush-Kuhn-Tucker, estão satisfeitas. Os solvers atuais não verificam se um problema a resolver satisfaz a condição de Slater, mas trabalham nesse pressuposto. Desenvolvemos e implementamos em MATLAB procedimentos numéricos para verificar se um dado problema de SDP é regular em termos da condição de Slater e determinar o grau de irregularidade no caso de problemas não regulares. Os resultados das experiências numéricas apresentados neste trabalho mostram que os procedimentos propostos são eficientes e confirmam as conclusões obtidas sobre a relação entre a condição de Slater e outras noções de regularidade. Outra contribuição da tese consiste no desenvolvimento e na implementação em MATLAB de um procedimento numérico para gerar problemas de SDP não regulares com um determinado grau de irregularidade. A colecção de problemas não regulares construídos usando este gerador é de acesso livre e permite testar novos métodos e solvers para SDP. Uma outra contribuição desta tese está relacionada com uma aplicação de SDP em análise de dados. Consideramos um modelo de SDP não linear, bem como as suas relaxações lineares para problemas de clusterização, e estudamos a sua regularidade. Mostramos que o modelo não linear é não regular, enquanto que as suas relaxações são regulares. Sugerimos um algoritmo baseado em modelos de SDP para resolver problemas de clusterização e redução de dimensionalidade, e implementámo-lo em R. Os testes numéricos usando vários conjuntos de dados confirmam a rapidez e eficiência deste procedimento numérico.

Die vorliegende explorative Studie will einen Beitrag zur Qualifikationsentwicklungs-forschung im Informationsbereich leisten, indem Stellangebote an Absolventen bibliotheks- und informationswissenschaftlicher Studiengänge aus dem Jahr 1996 sowie aus dem Zeitraum Oktober 2010 bis September 2011 einer Inhaltsanalyse unterzogen werden. Die gewonnen Daten der beiden Untersuchungszeiträume werden statistisch ausgewertet und unter Anreicherung qualitativer Betrachtungen verglichen.
Die Erhebung univariater Häufigkeitsverteilung soll dabei die Entwicklung einzelner Qualifikationsbereiche in den Anforderungen der Informationseinrichtungen beleuchten und Rückschlüsse auf markante Wandlungen des Berufsfeldes von Informationsfachleuten ermöglichen. Ergänzend sollen die Ermittlung bivariater Häufigkeitsverteilungen sowie eine Clusteranalyse häufig auftretende Merkmalskonstellationen herausfiltern und zu Anforderungsprofilen verdichten.
Insgesamt flossen 92 Anzeigen des Jahres 1996 und 211 Anzeigen aus dem Zeitraum 2020/ 2011 in die Analyse ein. Im Ergebnis zeigt sich eine deutliche Ausdifferenzierung der Qualifikationsanforderungen, die insbesondere auf einer Zunahme der Nachfrage nach IT- und Managementqualifikationen sowie überfachlichen Kompetenzen fußt.
Diese erweitern nach Maßgabe der untersuchten Stellenangebote traditionelle Anforderungsprofile der Sammlung, Erschließung und Vermittlung von Informationen und tragen zur Konstituierung neuartiger, stark informationstechnologisch fokussierter Qualifikationsprofile bei, ohne dem Stellenwert bibliothekarischer, archivarischer und dokumentarischer Fachqualifikationen Abbruch zu tun.

Full textAbstract:
We have considered the bilevel programming problem in the case where the lower-level problem admits more than one optimal solution. It is well-known in the literature that in such a situation, the problem is ill-posed from the view point of scalar objective optimization. Thus the optimistic and pessimistic approaches have been suggested earlier in the literature to deal with it in this case. In the thesis, we have developed a unified approach to derive necessary optimality conditions for both the optimistic and pessimistic bilevel programs, which is based on advanced tools from variational analysis. We have obtained various constraint qualifications and stationarity conditions depending on some constructive representations of the solution set-valued mapping of the follower’s problem. In the auxiliary developments, we have provided rules for the generalized differentiation and robust Lipschitzian properties for the lower-level solution setvalued map, which are of a fundamental interest for other areas of nonlinear and nonsmooth optimization.
Some of the results of the aforementioned theory have then been applied to derive stationarity conditions for some well-known transportation problems having the bilevel structure.
