Full textAbstract:
Soybean quality is typically measured by protein values. Essential Amino Acids (EAA) and Critical Amino Acid Value (CAAV) provide alternative measures of valuing soybeans. The following thesis analyzes the effects of testing soybeans for specific quality traits. A dual-marketing system is developed to analyze the costs and risks that may arise for grain handlers to segregate soybeans into high-quality and low-quality grain flows based on various importer purchasing strategies. A stochastic optimization model is used to determine the optimal testing locations within the dual-marketing system in order to minimize costs and risks to grain handlers. The model includes a blending component to determine the optimal blending from different locations with various quality distributions. The thesis provides a framework for grain handlers to make decisions based on the international importers? various and numerous purchasing strategies.

Nas últimas décadas houve um grande avanço em pesquisas no desenvolvimento de medicamentos à base de plantas medicinais. Entretanto, constata-se que há pouca preocupação sobre as concentrações de elementos estáveis, bem como as concentrações de atividade de radionuclídeos naturais das séries do 238U e 232Th em plantas com esta finalidade no Brasil. A presença de minerais e radionuclídeos em plantas constitui um meio de migração destes elementos para o organismo humano, através da ingestão de chás ou medicamentos feitos com ervas medicinais. Peperomia pellucida é conhecida popularmente por erva de jabuti e por suas propriedades medicinais, como cicatrizante, analgésica, bactericida e fungicida. As amostras de Peperomia pellucida e de solo analisadas neste trabalho foram coletadas no Jardim Botânico do Rio de Janeiro e em suas proximidades. A concentração elementar de As, Ba, Br, Ce, Cl, Co, Cr, Cs, Eu, Fe, Hf, K, La, Lu, Mg, Mn, Na, Nd, Rb, Sb, Sc, Sm, Ta, Tb, Th, U, Yb e Zn foi determinada nas folhas, partes aéreas, compreendendo folhas e caule, e raiz de Peperomia pellucida, nos extratos obtidos por maceração e infusão e no solo pela técnica da Análise por Ativação Neutrônica Instrumental (AANI). O método analítico utilizado para determinar os elementos Cd, Hg e Pb foi a Espectrometria por Absorção Atômica e as atividades de 226Ra, 228Ra e 210Pb foram determinadas pela contagem alfa e beta total após separação radioquímica. A qualidade dos resultados obtidos foi verificada pela análise dos materiais de referência certificados IAEA-336 Lichen, IAEA-Soil-7, IAEA-326 Radionuclides in soil, NIST 1515 Apples Leaves e NIST 1542 Peach Leaves. Os resultados obtidos nas análises apresentaram boa precisão e exatidão. O óleo essencial e os extratos etanólico e hexânico obtidos das partes aéreas de P. pellucida foram testados in vitro, em placas de Petri, para verificar a atividade antifúngica diante ao fungo Aspergillus flavus. A atividade antifúngica baseou-se na zona de inibição e nos valores de CI50 frente ao patógeno. Também foi determinada a composição química do óleo essencial pela Cromatografia Gasosa acoplada ao Espectrômetro de Massa (GC-EM).In recent decades, there has been a great advancement in research in developing drugs from plants. Nevertheless, little significant care exists in the literature about the stable concentration of elements, as well as the activity concentration of 238U and 232Th decay products in plants used for this purpose in Brazil. The presence of stable elements and radionuclides in plants constitutes the pathway for their migration to humans, via uptake of tea or remedies made with medicinal herbs. Peperomia pellucida, whose popular name is erva de jabuti, is a plant known by its medicinal usages, such as healing and analgesic properties plus antibacterial and antifungal activities against food fungi. In this study, the elemental composition of Peperomia pellucida and surrounding soil samples collected in the Botanical Garden in Rio de Janeiro was determined; the elemental concentration in the alcoholic extract and infusion processes of dry plants was also determined. The elemental concentration of As, Ba, Br, Ce, Co, Cr, Cs, Eu, Fe, Hf, K, La, Lu, Na, Nd, Rb, Sb, Sc, Sm, Ta, Tb, Th, U, Yb and Zn was determined in the leaves, aerial parts, including leaves, stems and roots of Peperomia pellucida, in their extracts obtained by maceration and infusions and in the surrounding soil by the Instrumental Neutron Activation Analysis (INAA). The analytical methodology used to determine the elements Cd, Hg and Pb was the Atomic Absorption Spectrometry (AAS); the activities of 226Ra, 228Ra and 210Pb were carried out by gross alpha and beta counting, after radiochemical separation. The quality of the obtained results was assured by the analyses of the certified reference materials IAEA-336 Lichen, IAEA-Soil-7, IAEA-326 Radionuclides in soil, NIST 1515 Apple Leaves and NIST 1542 Peach Leaves. The relative standard deviations and the relative errors obtained in these analyses indicated good precision and accuracy of the results. The essential oil, ethanolic and hexane extracts of Peperomia pellucida were tested for antifungal activity against Aspergillus flavus in vitro on Petri plates. The antifungal activity was based on the inhibition zone and IC50 values against the pathogen on Petri plates assays. Also, the essential oil chemical composition was determined by GC-MS.

Le gene e2a d'adenovirus, exprime durant la phase precoce de l'infection, sous le controle des proteines virales e1a et e4, est un excellent systeme-modele pour l'etude des mecanismes impliques dans la regulation de l'expression des genes transcrits par l'arn polymerase b (ou ii). L'analyse detaillee de la structure de ce promoteur a notamment revele l'existence de deux sites e2f, d'un site atf et de plusieurs sites c alpha, essentiels a la fois pour l'activite basale et la transactivation du gene par les proteines e1a et e4. Nous avons determine la contribution respective de chacun de ces elements dans le controle de l'activite du promoteur e2a et tente de caracteriser les mecanismes mis en uvre. Ainsi, nos resultats permettent de conclure que l'activation du promoteur par e1a implique des interactions directes entre cette proteine et le facteur atf, ainsi qu'une modulation eventuelle des liaisons des facteurs e2f et c alpha sur des sites communs. L'activation par e4 resulte d'une interaction de cette proteine avec le facteur e2f qui entraine la fixation cooperative de 2 molecules e2f sur le promoteur. D'autre part, l'etude de la regulation du promoteur e2a par les proteines e1a et e4 dans des cellules d'embryocarcinomes de souris, avant et apres differentiation, nous a permis d'approcher certains aspects de la differentiation cellulaire. Ainsi, nous avons pu etablir une relation entre l'activite du promoteur e2a et la presence de la proteine du retinoblastome qui module l'activite du facteur e2f et la presence de la proteine du retinoblastome qui module l'activite du facteur e2f en se complexant a celui-ci

This paper seeks to resolve the biggest problem with hearing aids, their physical fit. By digitally scanning the ear canal and taking the dynamics of the ear into account the performance and comfort of a hearing aid can be greatly improved. Current optical techniques for 3-D imaging are too expensive to be implemented in the ear canal for the purpose of custom fitted hearing aids. A new absorption based optical technique is introduced, which is capable of generating three dimensional maps of an ear subjected to a varying pressure. Specifically a hearing aid can be constructed with allowances for the compliance of the ear and the distortions associated with jaw movement. It is shown that the information that can be captured with this new technique will be of value toward improving hearing aids, and that the hearing aid industry is ready to take advantage of a digital scanner. A one dimensional calibration was made, and qualitative 3-D data is shown. The imaging technique was implemented with much lower cost equipment then would be needed by other 3-D techniques such as interferometry. A technique for the laboratory manufacture of brushed on fluorescent balloons was presented that are suitable to be used by this imaging technique to measure the dynamics of the ear. The bulk compliance of a human ear in vitro was measured with a laboratory fabricated balloon.

Wohlman, Katharine Jane. "Ear-tudes: an ear training method for the collegiate tubist." Diss., University of Iowa, 2013. https://ir.uiowa.edu/etd/2662.
Full textAbstract:
Traditionally, collegiate ear training classes in the United States are comprised largely of notation-based exercises and assignments, administered to small groups by a single teacher. Aside from the piano, instruments generally are not used during ear training classes, de-emphasizing the perceived correlation between students' aural skills development and their progress as instrumentalists.
By studying the history of music education, and examining current aural skills pedagogy, the author has found that common practice often relies on notation-based tasks as a measurement of success, despite the fact that research supports the effectiveness of aural-based learning.
In order to encourage a better understanding of pitches and rhythms, the author composed fifteen original etudes ("Ear-tudes") for tuba with accompanying drills. Before revealing each Ear-tude, the instructor leads the student through related drills. Each of the Ear-tudes focuses on a particular interval, scale-type, rhythmic, or tonal challenge, within a variety of meters, tempi, and styles, all of which are suitable for the typical first year tuba student. This method provides an innovative way for tuba teachers to integrate ear training into their instruction, alongside a new collection of etudes designed specifically for freshman students.

Full textAbstract:
Hearing loss is a very common birth defect. However, current hearing screening does not provide adequate specificity. Tympanometry is a potential hearing-screening tool that is specific to conductive hearing loss, but the tympanograms of newborns are currently not standardized and not well understood. Finite-element models of the newborn ear canal and middle ear are developed and their responses to the tympanometric probe tone are studied. Low-frequency and dynamic simulations are used to model the ear's response to sound frequencies up to 2000 Hz. Material properties are taken from previous measurements and estimates, and the sensitivities of the models to these different parameters are examined. The simulation results are validated through comparison with previous experimental measures. Finally, the relative admittances of the ear canal and the middle ear at different frequencies are examined and implications for the interpretation of newborn tympanometry are discussed.La perte d'audition est une anomalie congénitale très courante. Toutefois, le dépistage auditif actuel n'est pas spécifique. La tympanométrie est un dépistage auditif potentiel qui aide à dépister la surdité de transmission, mais les tympanogrammes des nouveau-nés ne sont pas bien compris ou standardisés. Deux modèles d'éléments finis ont été développés: l'un pour le conduit auditif des nouveau-nés, et l'autre pour l'oreille moyenne. Leurs réponses au ton de sonde tympanométrique sont étudiées. Les simulations quasi-statiques et dynamiques sont utilisés pour modeler la réponse de l'oreille aux fréquences de son jusqu'à 2000 Hz. Les propriétés matérielles sont prises des mesures et des estimations précédentes, et les sensibilités des modèles à ces différents paramètres sont examinées. Les résultats des simulations sont validés par la comparaison avec les mesures expérimentales précédentes. Enfin, les impédances relatives du canal externe de l'oreille et de l'oreille moyenne aux fréquences différentes sont examinées et les implications pour l'interprétation de la tympanométrie du nouveau-né sont discutées.

Full textAbstract:
Ce travail apporte de nouvelles orientations pour la fabrication d'émulsions multiples e/H/E. Deux stratégies sont développées sur la base d'un concept de formulation généralisée à l'aide d'une méthode de suivi in situ simultané de conductivité électrique et de viscosité pendant l'élaboration de ces émulsions multiples. La première stratégie consiste en un procédé deux étapes-"one batch", dans lequel l'émulsion est élaborée dans une cuve de mélange unique grâce à un positionnement judicieux d'un mobile d'agitation. La diminution de la tension interfaciale dans le système par variation de formulation permet de réduire considérablement la taille des gouttelettes d'eau de l'émulsion primaire, et ce, même avec un apport d'énergie mécanique modérée. La seconde stratégie concerne un procédé en une étape, au cours duquel deux courbures opposées sont créées simultanément par association d'effets de formulation et de composition. Le contrôle et le suivi du pourcentage de phase interne permettent d'envisager la systématisation du protocole d'élaboration des émulsions multiples et des conditions opératoires afférentesThis work deals with the development of new routes for the preparation of w/0/W multiple emulsions. Two strategies were developed on the basis of a Generalized Formulation Concept, thanks to an in situ follow-up method allowing the simultaneous measurement of electrical conductivity and viscosity during the fabrication process. The first strategy deals with a "two steps-one batch" process, during which the multiple emulsion is obtained in a single mixing vessel thanks to a specific positioning of an agitation mobile. The decrease of the interfacial tension in the system through a formulation change allows to considerably reduce the primary emulsion drop size, even in the case of a moderate mechanical energy supply. The second strategy deals with a one step process, in which two opposite curvatures are simultaneously created through the association of both formulation and composition effects. The control and the follow-up of the internal phase content allow to envision the possibility of systematising the protocol of multiple emulsion elaboration as well as the corresponding operating conditions

Due to the rapid changing environment many organizations are striving to achieve agility and flexibility in internal and external environments. In order for an enterprise to be able to respond to this changing environment, it must integrate the business functions into a distinct system that is capable of exploiting information technology competently. Enterprise Resource Planning (ERP) mainly focused on integrating internal business functions and implementing an ERP system requires a significant amount of time and financial resources. Moreover, ERP systems are complex, non-flexible and are not capable of collaborating with autonomous application leading to difficulty in integration and customization [3]. Enterprise Application Integration (EAI) is an alternate technology to ERP where the integration process is automated without much effort. This research work mainly focuses on designing an order processing system using the concepts of EAI for Intra Organization in any small and medium enterprises (SME’s). As a result of this research work, a five layered architecture has been designed which can be integrated in any enterprise without affecting the existing business workflow. This architecture is categorized into Data Layer, Middleware Layer, Event Generation Layer, Translation Layer and Interface layer. Further to actually test the extent and reliability of this architecture a prototype system implementation is built at Hyundai Mobis Parts- Sweden, using the concepts of EAI. In addition the evaluation of the prototype system is performed to check the above defined layers of the architecture.

Electronic article surveillance (EAS) is widely used in shops and libraries together with an RF-tag attached to the goods or books in order to prevent shoplifting. By implementing the addition of a moisture sensor to the RF-tag, other functions become possible, including the ability to use as an alarm with regards to frozen goods, which have been shipped but which have melted and have, subsequently, refrozen. In- relation to care for the elderly, one time-consuming step involves checking whether there is the necessity for a change of diaper and this can, instead, be based on an RF-tag with an EAS-system alarm. A preliminary investigation was made using the moisture sensors, which involved how the resistance changes when liquid and/or heat is applied. A simulation of the LCCR circuit (RF-tag with the sensor) was conducted in order to determine how the resonance frequency changes for different resistances levels. When the moisture sensors are applied to the RF-tag with the correct resistance no alarm will be triggered, but will be triggered when water is added to the moisture sensor. In order for the tag to be able to induce energy from the transmitter in the EAS-system the resistance must be less than ten ohms in relation to the entire tag. Results show that the implementation of the sensor on the RF-tag is possible and that it works in a satisfactory manner.Elektroniska varularm EAS (Electronic article surveillance) är vida använt i butiker och bibliotek tillsammans med RF-tagg som är fäst på varor böcker för att förhindra snatteri. Genom att implementera fuktsensor till RF-taggen kan den få andra funktioner som då kan användas till larm om frysvaror fraktas har tinat men fryst igen, samt till äldrevården där ett tidsdödande moment är att hela tiden kontrollera om vårdtagaren behöver byta blöja. I stället kan RF-taggen med EAS-systemet larma. Förundersökning gjordes med fuktsensorn som är en sensor för hur resistansen ändras när vätska och värme förs på den. Simulering av LCCR krets (RF-tagg med sensor) gjordes för att se hur resonansfrekvensen ändras vid olika resistansnivåer. När fuktsensorn är applicerad på RF-tagg med rätt resistans triggas inte alarm, men däremot när vatten förs på fuktsensorn. För att taggen ska kunna inducera energin från sändaren i EAS-system måste resistansen vara lägre än tio ohm på hela RF-taggen. Resultatet visar att implementering av sensor på RF-tagg är möjlig och fungerar.

Full textAbstract:
Early hearing screening and diagnosis in newborns are important in order to avoid problems with language acquisition and psychosocial development. Current newborn hearing screening tests cannot effectively distinguish conductive hearing loss from sensorineural hearing loss, which requires different medical approaches. Tympanometry is a fast and accurate hearing test routinely used for the examination of conductive hearing loss for older children and adults; however, the tympanograms are hard to interpret for newborns and infants younger than seven months old due to significant differences in the outer and middle ear. In this work, we used the finite-element method (FEM) to investigate the behaviour of the newborn canal wall and middle ear in response to high static pressures as used in tympanometry. The model results are compared with the analysis results of multi-frequency tympanometry measured in healthy newborns and with available tympanometry measurements in newborns with presumed middle-ear effusion. Analysis results of multi-frequency tympanometry show that both susceptance and conductance increase with frequency. The equivalent volumes calculated from both tails of both the admittance and susceptance functions decreased as frequency increases. The volumes derived from susceptance decrease faster than do those derived from admittance. The 5th-to-95th percentile ranges of equivalent volume and energy reflectances are much lower than previous measurements in older children and adults. Non-linear finite-element models of the newborn ear canal and middle ear were developed. The ear-canal model indicates that the Young's modulus of the canal wall has a significant effect on the ear-canal volume change, which ranges from approximately 27% to 75% over the static-pressure range of ±3 kPa. The middle-ear model indicates that the middle-ear cavity and the Young's modulus of the tympanic membrane (TM) have significant effects on TM volume displacements.

Les épreuves actuelles de dépistage de l'audition des nouveau-nés ne permettent pas de distinguer efficacement entre une perte auditive due à une surdité de transmission et une perte sensorineurale, chacun de ces troubles exigeant un traitement médical différent. La tympanométrie est une épreuve rapide et exacte que l'on utilise habituellement pour déceler une perte auditive due à une surdité de transmission chez les enfants plus âgés et chez les adultes. Cependant, dans le cas des nouveau-nés et des enfants en bas âge, les tympanogrammes sont difficiles à interpréter en raison de différences importantes dans l'oreille moyenne et externe. Dans cette étude, nous avons utilisé l'analyse par éléments finis pour examiner les comportements que manifestent la paroi du conduit auditif et l'oreille moyenne des nouveau-nés en réaction aux pressions statiques élevées utilisées en tympanométrie. Les résultats du modèle sont ensuite comparés aux résultats d'analyses de tympanométrie multifréquence effectuées sur des nouveau-nés en santé, et aux mesures tympanométriques disponibles réalisées sur des nouveau-nés souffrant d'un épanchement présumé dans l'oreille moyenne. Les résultats d'analyses de tympanométrie multifréquence indiquent que tant la susceptance que la conductance augmentent avec la fréquence. Les volumes équivalents calculés à partir de deux extrémités des fonctions d'admittance et de susceptance décroissent à mesure que la fréquence augmente. Les volumes issus de la susceptance diminuent plus rapidement que ceux issus de l'admittance.

Network administrators typically employ di erent methods for authenticating and authorizing the access to their networks. A exible and scalable network access method is needed to combat the ever increasing network ubiquity brought on by technological advancements. The IEEE 802.1x Port-Based Network Access is a technology that allows transparent authentication to a network. It uses EAP-methods in order to authenticate against a server. There are a lot of di erent EAP-methods to choose from, and they vary in complexity and security. This report will bring up the di erences between the most commonly used authentication methods regarding the authentication time depending on di erent delay and network load. Results showed that EAP-methods that are less complex take less time to perform authentication than their counterparts. When there is no delay, or a very small delay, this might not matter, but when the delay is higher complex EAP-methods take signi cantly longer time to perform the authentication process. This is very negative considering the nature of transparent authentication, and could lead to users becoming annoyed. A general formula for determining how long time an EAP-authentication process will take is presented.

The main objective of the present work was to investigate the opportunity for the use of light hydrocarbons as quenching agents to quench high temperature gas streams. When light hydrocarbon, for example propane, is introduced into a hot gas, for example synthesis gas, the cooling of hot gas will occur both by dilution and by endothermic reactions of hydrocarbon. Thus, the hot gas may be quenched to a lower temperature. At the same time, thermal energy present in the hot gas may be recovered in the form of desired products that are produced during hydrocarbon cracking. This type of quenching is called for chemical quenching. A proof-of-concept study would be performed, but was not completed because of problems with a realization of experimental conditions and problems with equipment.Methane pyrolysis experiments were performed at high temperatures 1400 and 1450 °C. Short residence times and high dilution with hydrogen were applied in order to minimize coke formation. Methane conversions, selectivities and yields of products for different experimental conditions were calculated from the gas chromatographic analysis. The aim of pyrolysis experiments was to validate that the experimental set-up Pyrolyserigg works properly. This was done by comparison of experimental results with results that were obtained before on the same set-up and by comparison with a literature data. After the work of Pyrolyserigg was verified, it was possible to modify existing cooling/quenching system. A new quencher part that gives opportunity to introduce a cold gas into hot gas, heated by high temperature furnace, was designed. The quencher part was designed in a way that the temperature of hot gas entering the quencher and temperature of cooled gas mixture leaving the quencher could be measured. Thus, quenching effect (temperature drop) could be measured.Three types of experiments were performed after modification of cooling system: experiments with only hot inert gas (N2), experiments with a hot nitrogen gas «quenched» by methane, and hot nitrogen gas quenched by propane. Hot gas temperature and gas flows were varying in order to study the modified system's behaviour. Experiments with a hot nitrogen showed that there is a limit for maximum obtainable temperature inside the quencher, 1195 – 795 °C, for the given quencher design. A high temperature gradients between measurements points were registered that may be an indication of high heat losses. The temperature gradient increases with increasing gas temperature and decreases with increasing gas flow.Quenching effect (temperature drop) was measured in quenching experiments with propane, and expected temperature drop was calculated for the applied experimental conditions. Low measured temperature drop in quenching experiments indicates poor mixing of hot and cold gases. Quenching effect of propane introduction increases with increasing hot gas temperature because heat consumption by endothermic reactions increases, that is a consequence of increasing propane conversion.A product mixture from quenching experiments with propane was analysed, and conversion of propane, yield and selectivities to products were calculated. Ethylene and propylene are considered to be most valuable products. Ethylene yield increases with conversion and is around 37 % at 100 % conversion. Propylene yield goes through a maximum at 55 % conversion and approaches zero at 100 % conversion. The main identified problems for the proof of concept study are a poor gas mixing, high temperature gradients through the quencher and high heat loss from the quencher part. In addition, problems with connection ceram tube – quencher at high temperature have occurred.

The first chapter of this thesis begins with an introduction to the background associated with the research project and an overview of significant issues in English for Academic Purposes (EAP) and its assessment. This leads on to an explanation of the need for EAP Assessment Literacy. It is clarified, through reference to the research questions, that this study has been undertaken in order to investigate the extent to which the views of EAP teachers, on the topic of EAP testing and assessment, reflect language testing research and practices which comprise Assessment Literacy. Statement of the research questions and the hypothesis under investigation also explains that the thesis aims to ascertain how EAP Assessment Literacy can be sustained or enhanced. Chapter 2 of the study presents the Literature Review which examines the conceptual frameworks surrounding Assessment Literacy and the context of EAP. The views of key proponents of Assessment Literacy are discussed alongside a review of associated research in the fields of Education, Applied Linguistics and EAP. Other resources and mechanisms available for the enhancement of Assessment Literacy through formal training or in-service learning opportunities are also discussed. In the third chapter, the Research Design and Methodology, the researcher’s philosophical approach is rationalised and an appropriate set of research methods for this enquiry into EAP Assessment Literacy is identified. For this particular study the choice of a pragmatic paradigm is clarified. A mixed methods approach is also described in addition to the design of a questionnaire and an interview protocol for data collection purposes. Chapter 4 presents the Findings section of the research. Features of the research participant population are described and, in the case of the questionnaire, a method for filtering the total number of respondents to provide a more representative group is outlined. The results from the two main research tools are then presented in terms of key sets of data. These data sets include different question types and investigate the key areas of Assessment Literacy in EAP. Through Chapter 5, Analysis and Discussion, the meaning revealed within the Findings chapter is interpreted further. This will serve to identify key information relating to EAP teachers’ views on EAP testing and assessment practices and the extent to which these reflect language testing research practices which comprise Assessment Literacy. A synthesis of the main outcomes of the research is then provided in Chapter 6, Conclusions and Recommendations. Suggestions regarding what needs to be undertaken in order to sustain or enhance EAP teacher Assessment Literacy are also provided in the recommendations. In addition, the limitations of the study are also acknowledged, so that the scope of the research is appropriately contextualised. In Chapter 7, a list of references is provided detailing resources which have been cited during the research. Finally, an Appendix is included in Chapter 8 which includes the full questionnaire and the full set of interview questions. Access is also provided to transcripts from each of the interviews, the series of open question responses from the questionnaire and number of charts and diagrams which are not included in the main body of the thesis.

Full textAbstract:
Humans can recognise individuals in many different situations. Automated vision-based biometric systems, which identify individuals from an image of a particular physical feature, aspire to a similar level of performance but currently have to impose constraints to achieve satisfactory recognition rates. These include limitations on the background of the image in which a feature is located, the lighting on the feature, its degree of occlusion, its viewed angle, and the properties of the camera that captures it. The computational cost of any recognition system is also an issue. This thesis examines ways of reducing such constraints. Its particular focus is the recognition of individuals from the unique signature provided by their ears. Speciffically, the work develops techniques to support a hypothesis that: The constraints on the use of ear-based biometric systems can be relaxed significantly through the introduction of robust recognition techniques. Two novel techniques designed to improve robustness are described: (i) a fully automated 2D recognition system to reduce sensitivity to noise and occlusion; and (ii) the use of a 3D model to allow for variations in both pose and lighting; The thesis begins by summarising current progress in the general field of biometrics and in the associated techniques for robust recognition. Each technique is then described in successive chapters, identifying related work, explaining the technique in detail and evaluating its performance. Future work will focus on developing algorithms to enable the 3D model to be accurately fitted to images. A number of developments in this area are outlined in the appendix. While these techniques have been developed for ear recognition they also contribute to the general research challenge of recognising any object in any environment

Full textAbstract:
L’eau est un élément doté de fonctions multiples, de différentes manifestations et de titres pluriels, qui, s’additionnant à son état de pénurie, en font une ressource faible, ce qui lui donne une valeur économique. L’imminence de conflits hydriques face à cette pénurie a fait surgir le droit universel à l’eau, patrimoine commun de l’humanité. Cela reflète son caractère unitaire, que l’on constate dans le cycle hydrologique. La pollution hydrique nous amène à l’application du principe du pollueur-payeur, manifestation négative de la valeur économique de l’eau. Les principes de l’usager-payeur et du développement durable, à leur tour, déterminent la gestion de l’ environnement de manière durable, équilibrée, participative et intégrée, selon leurs prémisses, leurs valeurs et leurs instruments. La valeur économique est un fondement de la politique des eaux – en France et au Brésil –, et se crée par la tarification de l’eau. La relation hydrique, juridique et économique de cette tarification présente plusieurs particularités, qui doivent être mieux appréciées par le droit. L’ application de la tarification requiert l’obéissance au droit fondamental à l’eau et aux principes de gestion des eaux dans la formation du prix. La méthodologie économique est au service de la composition du prix. Il ne faut pas oublier la coopération éthique et solidaire des usagers de l’eau, ainsi que l’application du principe de la subsidiarité. Le Pouvoir Public, enfin, fiscalise et punit la désobéissance, assurant la légalité de l'application juridique de la tarification de l' eauWater is an element multiple functions, different manifestations and plural titles which, added up to its current state of penury, make it a scare resource, soon lacking economic value. The eminence of hydro-conflicts, due to the hydric penury, has caused the uprising of the universal right to water, which has echoed into the juridical nature of common patrimony of Mankind, reflecting its unitary character estified in the hydrologic cycle. This patrimonialization of water declared by the Law has revealed the embryonic manifestation of the juridical-economic value of water. Hydric pollution leads to the application of the pollutant-payer, a negative manifestation of the economic value of water, which has in the user-payer principle and in the principle of sustainable developement, determined its management in a sustainable, balanced, participative and integrated form. To make it possible it is necessary to have premises, values and instruments. The economic value is a fundament of the water policies – both in France and in Brazil, being instrumented into the charge for water taxes. The hydro-juridical-economic relation of this charge is provided by juridical peculiarities which must be better put into effect by means of the Law. The application of charges requires the observation of the fundamental right to water and of the principles of the management of water in the price formation, which must be done faithfully. The economic methodology is put into the service of this formation which lends some of its instruments, in the aim of accomplishing the price composition, through the ethical and solidary cooperation of its users and the application of the principle of subsidiarity which has an important subject in the local community and the Judiciary Power to fiscalize and punish its disobedience, thus assuring the legality of the juridical application of the water charge taxes

A inserção das tecnologias da informação e comunicação na educação é uma realidade presente que vem ao encontro da concretização das políticas governamentais de expansão da educação superior no país. Para tanto, a educação a distância vem tomando proporções importantes no cenário nacional, merecendo atenção por parte da comunidade acadêmica. Os papéis exercidos por professores e alunos no processo de ensino-aprendizagem mudam e surge ainda o papel do tutor, não existente nos modelos tradicionais. Toda essa mudança exige, especialmente dos professores, um conjunto de competências específico. Neste sentido, o objetivo deste trabalho é analisar em que grau são requeridas as competências necessárias para o exercício da docência tomando como base o estudo do curso de graduação em Administração a distância da Universidade Federal de Santa Catarina. Para tanto, se desenvolveu uma pesquisa considerando como categorias de análise: competência e desenvolvimento de competências docentes. A pesquisa teve abordagem qualitativa e exploratória em sua primeira etapa e quantitativa e descritiva na segunda, caracterizando-se também como aplicada, bibliográfica e estudo de caso no projeto-piloto do referido curso. A coleta e análise de dados deram-se por meio de pesquisa documental e bibliográfica e mais especificamente entrevistas e análise do discurso na primeira etapa e aplicação de questionários e análise estatística na segunda. Percebeu-se que o estado da arte mostra-se incipiente quanto às competências específicas para atuação em EaD. Portanto foi desenvolvida a primeira etapa da pesquisa, na qual das análises das entrevistas derivou um conjunto de 32 competências divididas em competências técnicas e comportamentais. Estas foram agrupadas em três momentos de atuação do professor identificados nas entrevistas: contato com o aluno, produção de material didático e contato com o tutor. Na segunda etapa da pesquisa foi estabelecida uma escala de medição com cinco graus, com o objetivo de que os professores, tutores e alunos atribuam graus de necessidade para cada competência. De maneira geral pode-se inferir que as respostas dos alunos apresentam valores ligeiramente mais baixos, mas há coerência e homogeneidade nas respostas das três classes, demonstradas pelos baixos desvios padrão e coeficientes de variação percentual. Todas as médias atingiram graus superiores a 3, o que classifica todas as competências analisadas com graus de necessidade de médio a muito forte. Conclui-se que tanto professores como tutores e alunos tem clareza quanto ao que é requerido do docente para atuação na EaD, pois, embora hajam pequenas divergências nas médias mais elevadas em alguns grupos de competências, nota-se que essas diferenças não chegam a alcançar 1 ponto da escala utilizada.

Full textAbstract:
The present study was undertaken to evaluate the rat as a model for middle ear research. The rat was chosen primarily because the gross structure of its middle ear shows several similarities to that of man. It was considered of great importance to make a thorough structural study of the rat middle ear and to compare the results with those reported for the human middle ear. The thesis therefore includes independent studies on various aspects of rat middle ear structure and function as well as a review of the literature. The most pertinent findings in the experimental part of this study were the following. The rat Eustachian tube consists of a nasopharyngeal, and a cartilaginous and bony portion. The orifice of the nasopharyngeal portion is composed of two soft tissue lips, which appear to be opened mainly by the action of the salpingopharyngeal muscle, but also by the levator and tensor veli palatini muscles. The cartilaginous portion appears to be opened solely by the tensor veli palatini muscle. The tensor tympani muscle seems to have no effect on the tube. A ciliated and secretory epithelium lines the inferomedial walls of the tube throughout its length. In the tympanic cavity these thelial cell types extend as two tracts - one anterior and the other inferoposterior to the promontory - which communicate with the epitympanic/attic compartments. The remaining parts of the tube and the tympanic cavity are covered by a squamous/cuboidal, non-ciliated epithelium. The subepithelial loose connective tissue contains vessels, nerves, and connective tissue cells, among these mast cells. The mast cells are confined to areas covered by the ciliated epithelium, and in the floor of the bulla, in the pars flaccida, and along the manubrial vessels. Glands are restricted to the Eustachian tube. In the clearance/transport of serum-like material, from the epitympanum towards the tube, hydrostatic forces appear to be important. The tympanic membrane is vascularized from meatal and tympanal vessels. Meatal vessels branch in the pars flaccida and along the handle of the malleus, where they are localized directly beneath the outer, keratinizing, stratified, squamous epithelium. Furthermore, meatal vessels form a vascular network at the junction between the fibrocartilaginous annulus and the tympanic sulcus. Tympanal vessels send branches to the periphery of the pars tensa, where they run immediately beneath the tympanal, simple, squamous epithelium. In the major portion of the pars tensa, no blood vessels were found. The rat stapedial artery is a thin-walled vessel with a wide lumen. Without branching, it runs through the tympanic cavity to the extratympanal regions it supplies. In contrast to the corresponding artery in man, the rat stapedial artery persists throughout life. The artery does not seem to be affected by the fluid produced during experimentally induced otitis media with effusion. The middle ear structure in the rat and in man show both similarities and differences. If the differences are kept in mind and considered, it would seem that the rat is indeed a suitable model for experimental middle ear research.digitalisering@umu

Full textAbstract:
Bakgrund: Antalet förstföderskor som använder sig av EDA har ökat och idag använder dryga hälften EDA under förlossning. Det är den mest effektiva smärtlindringsmetoden som förlossningsvården har att tillgå. EDA vid förlossning är dock förknippat med biverkningar och risker. Barnmorskor har en viktig roll att ge information och undervisning om smärtlindring till gravida kvinnor. Syfte: Syftet med studien var att undersöka förstföderskors kunskaper och behov av information om EDA inför förlossning. Metod: Studien genomfördes och analyserades med metoden kvalitativ innehållsanalys med induktiv ansats. Semistrukturerade intervjuer genomfördes med åtta förstföderskor. Resultat: De analyserade intervjuerna utmynnade i två huvudkategorier; EDA är en metod med fördelar och nackdelar och Förstföderskor har behov av olika information på olika sätt, med tre, respektive två, tillhörande underkategorier. Konklusion: Kvinnornas kunskaper varierade, och många var osäkra. De hade behov av olika information om EDA på flera olika sätt. De upplevde att det varken fanns tid eller möjlighet för diskussion om EDA med barnmorskor, vilket kunde bidra till en känsla av att inte ha fått tillräckligt med information. Barnmorskor behöver därför blir bättre på att erbjuda förstföderskor information om EDA, men även annan smärtlindring som används under förlossning, förslagsvis genom uttökad tid på MHV.Background: The number of primparas who use EDA has increased, and today more than half of them use EDA during childbirth. It is the most effective method of pain relief that is available in maternity care. EDA during childbirth is, however, associated with side effects and risks. Midwives have an important role to provide information and education about pain relief to pregnant women. Purpose: The purpose of this study was to investigate primiparas knowledge and need of information about EDA during childbirth. Method: The study was conducted and analyzed by qualitative content analysis method with inductive approach. Semi-structured interviews were conducted with eight primiparas. Results: The analyzed interviews resulted in two main categories; EDA is a method with advantages and disadvantages and Primiparas need different information in different ways, with three and two associated subcategories. Conclusion: The women's knowledges varied, and many were unsure. They needed different information about EDA in several different ways. They felt that there was neither time nor opportunity for discussion about EDA with midwives, which could contribute to a feeling of not having received sufficient information. Midwives must therefore improve in offering primiparas information about EDA, but also other forms pain relief used during childbirth, suggested by extended time at maternal health care.

Full textAbstract:
Une émulsion est un mélange de deux liquides non miscibles. Les émulsions les plus connues sont les émulsions eau dans huile (mayonnaise, vinaigrette) ou huile dans eau (crème cosmétique), mais il est aussi possible de réaliser des émulsions eau dans eau ou encore huile dans huile. Lorsque deux solutions aqueuses de polymères hydrosolubles incompatibles sont mélangées, on forme une émulsion eau dans eau. Comme toute émulsion, les émulsions eau dans eau sont thermodynamiquement instables et tendent vers une séparation de phase. Il faut donc stabiliser ces émulsions. Contrairement aux émulsions huile/eau, on ne peut pas stabiliser une émulsion eau dans eau par des tensioactifs moléculaires, parce que ces dernières présentent une tension interfaciale très faible, environ trois ordres de grandeur plus faible que celles des émulsions eau-huile. De plus, les émulsions eau/eau ont une interface diffuse, mesurant jusqu’à plusieurs dizaines nanomètres.Des études sur la stabilisation des émulsions eau/eau ont été menées et les principales approches sont soit de figer la phase continue afin de ralentir, voire stopper la déstabilisation (stabilisation cinétique) soit d'utiliser des particules pour stabiliser l'interface, cette dernière méthode est nommée stabilisation par Pickering. L’objectif de ce travail de thèse est de stabiliser les émulsions eau dans eau par des polymères présentant une affinité pour les deux phases composant l’émulsion et se localisant à l’interface. Une émulsion modèle à base de POE et de dextran est utilisée pour cette étude. Une vingtaine de polymères ont été testés pour et seules trois ont montré la capacité de stabiliser les émulsions : le chitosan, le diethylaminoethyl dextran (DEAED) et le propylene glycol alginate (PGA).Les interactions entre ces polymères et le POE ou le dextran ont été investiguées par diffusion de la lumière et la microstructure a été étudiée par microscopie confocale. L’effet du pH, de la force ionique, de la tension interfaciale et de la concentration de polymère a été étudiée pour mieux comprendre les mécanismes de la stabilisation. Les émulsions stabilisées sont caractérisées de manière approfondie avec le LUMiSizer©, et le LUMireader© qui permettent de suivre la turbidité au cours du temps, et par rhéologie. Enfin, afin de comprendre les critères permettant à un polymère de stabiliser les émulsions, le chitosan sera modifié chimiquement pour faire varier le degré d’acétylation et ainsi changer le taux de charge et de groupements hydrophobesEmulsions are formed when two non-miscible liquids are mixed. The best known are oil-water emulsions (eg cosmetic cream, mayonnaise), but it also is possible to make other types of emulsions such oil-oil or water-water (W/W) emulsions. To obtain the latter, two aqueous solutions of incompatible polymers are mixed. In order to use these kinds of emulsions for instance in the food industry, one needs to stabilize them. Unlike oil-water emulsions, the use of molecular surfactants to stabilize W/W emulsions is not possible, because they have a very low interfacial tension and a broad interface.Stabilization of W/W emulsions is well studied in the literature, mainly by gelling of the continuous phase, or by using particles as interface stabilizers, so-called Pickering effect. In this study, the objective was to stabilize W/W emulsions by polymers that have some affinity with both phases and locate at the interface. For that purpose, we used a model emulsion made of PEO (P) and dextran (D) as incompatible polymers. It was found that out of 16 polymers tested, mainly polysaccharides, only three show a stabilizing effect of emulsions: chitosan, diethylaminoethyl dextran (DEAED) and propylene glycol alginate (PGA). Interactions of these polymers with PEO and dextran were investigated with light scattering and the microstructures was studied by confocal laser scanning microscopy. The effects of pH, ionic strength, interfacial tension and polymer concentration were studied to understand mechanism of stabilisation. Emulsions were characterized by different techniques and especially by means of LUMisizer©, LUMiReader©,to follow turbidity as a function of time, and rheology. In order to understand why some polymers were able to stabilize water-in-water emulsions and other cannot, chemical modifications of chitosan were carried out to vary the amount of charges and hydrophobic groups. Subsequently, the effect of these modifications on the stability of the emulsions was investigated

"Le but de cette étude était d'analyser l'action de la diversité des invertébrés sur le fonctionnement de l'interface sédimentaire eau libre - eau interstitielle. Dans une approche expérimentale 4 colonnes de sédiment traversées par un flux d'eau et fonctionnant en parallèle sont utilisées : une colonne témoin sans invertébrés et des triplicats ensemencés en invertébrés. Durant des expérimentations de 20 jours, des paramètres physico-chimiques et microbiens ont été mesurés à plusieurs horizons dans les colonnes. Les effets de trois taxons détritivores présentant des modes de vie distincts (oligochètes tubificidés, crustacés asellidés et diptères chironomidés) ont été étudiés. Les expériences ont abouti aux résultats suivants : L'approche expérimentale développée a permis de reconstituer un système d'interface présentant une forte hétérogénéité spatiale. Les deux genres d'oligochètes tubificidés testés sont fonctionellement redondants pour la majorité des processus étudiés (processus microbiens aérobies et anaérobies). Les trois groupes taxonomiques testés peuvent être classés dans trois groupes fonctionnels distincts car ils produisent des effets différents sur le fonctionnement de l'interface sédimentaire. Les interactions entre les taxons peuvent avoir un impact important sur le fonctionnement du système (transfert et transformation des nutriments). L'augmentation de 2 à 3 taxons détritivores par colonne n'a aucun effet significatif sur les fonctions mesurées (dénitrification, dégradation de la matière organique en anaérobiose, respiration aérobie). Ce résultat semble lié à une intensité de bioturbation "optimale" effectuée sur toute la surface de la colonne sédimentaire par 2 ou 3 taxons. En conclusion, les invertébrés et leur diversité ont un rôle important sur la régulation des flux d'énergie à l'interface eau libre - eau interstitielle. Cette diversité fonctionnelle doit être prise en compte dans l'étude des grands cycles biogéochimiques aux interfaces eau - sédiment"

O chumbo é um metal muito tóxico e que tem ampla distribuição pela sua grande utilidade. Mesmo a exposição a baixos níveis (que não causam sintomas de intoxicação aguda) de chumbo é associada a desordens cognitivas e neurológicas. O osso é considerado o melhor marcador de exposição a chumbo. No tecido ósseo, vários elementos estão presentes, e alguns deles poderiam ter sua concentração modificada pela exposição a chumbo. Testou-se a hipótese de que haja variações nos elementos Zn e Mg nas tíbias de animais expostos a chumbo (por técnica de química analítica convencional). Testou-se também se variações em microelementos poderiam ser detectadas por técnicas semiquantitativas nas tíbias de controles e animais expostos a chumbo. O objetivo deste projeto foi caracterizar em animais expostos ao chumbo desde a gestação e controles as concentrações deste elemento no osso (tíbia) de animais de 28 e 60 dias. Além do chumbo, investigamos também a concentração de 2 outros microelementos no osso: zinco e magnésio. As medidas quantitativas de chumbo foram feitas no sangue total coletado ao final dos períodos. As medidas quantitativas de chumbo, cálcio, zinco e magnésio foram realizadas a partir de soluções ácidas obtidas pela dissolução total do osso, sendo estas utilizadas para quantificar por Espectrometria de Absorção Atômica no modo chama ou com Forno e Grafite. Mandíbulas foram análisadas em Microscopia Eletrônica de Varredura e utilizando os acessórios Eletron Dispersive Spectroscopy para os elementos mais abundantes e Wavelenght dispersive Spectroscopy para investigar por análise semiquantitativa os mais abundantes elementos inorgânicos no osso destes animais, como forma de verificar se há variações nestes microelementos nos animais expostos a chumbo em comparação com controles. Como o chumbo se concentra na superfície do esmalte, também analisou-se o esmalte de primeiros molares inferiores, a fim de verificar se era visto o sinal do elemento chumbo nestes dentes. Foram usados ratos Wistar machos de 28 e 60 dias divididos em 2 grupos: C 28D (n=5) e Pb 28D (n=5) e, C 60D (n=12) e Pb 60D (n=17). Em todas as medidas de chumbo dos grupos controle as concentrações obtidas foram próximas ao limite de detecção, e houve sempre diferença estatisticamente significante (P<0.0001) quando os controles foram comparados aos grupos expostos a chumbo. As concentrações de chumbo obtidas no sangue de animais do grupo Pb 28D foi de 8,0 ug/dl (± 1.1) e no grupo Pb 60D foi de 7,2 ug/dl (± 0.89). Houve diferença estatisticamente significante entre as massas das tíbias (aferidas em balança e também a partir da quantidade de cálcio dissolvida em solução) do grupo C 60D (0,86 g ± 0,13) e Pb 60D (0,61 g ±0,11)(p=0.0004). As concentrações de chumbo detectadas nos ossos do grupo Pb 28D foi 8,02 (± 1,12) e no grupo Pb 60D foi de 43,3ug/g (± 13,26). Concentração de zinco no osso do grupo C 60D foi 0,22 mg/g e no grupo Pb 60D foi 0,22 mg/g (p>0.05). A concentração de magnésio no osso do grupo C 60D foi de 4,89 mg/g ± 0,74 e no grupo Pb 60D foi de 4,98mg/g ±0,79 (p>0.05). Os microelementos mais abundantes detectados nas tíbias contralaterais por Microscopia Eletrônica de varredura por EDS/WDS foram cálcio, fósforo, carbono, oxigênio, magnésio, sódio e potássio, não tendo sido detectadas variações nestes elementos entre os grupos controle e expostos a chumbo de 60 dias. O chumbo foi detectado apenas na região cervical dos dentes molares por MEV-EDS, e, nesta posição, apenas na forma de óxido de chumbo (deposição extrínseca) que pode ser útil para fins forenses ou de determinação de contaminação desconhecida. As conclusões deste estudo são: Houve diferença estatisticamente significante entre as massas de osso do grupo Pb 60D e C 60D. Mesmo não havendo diferença entre as concentrações de chumbo no sangue total de animais de 28 e 60 dias, houve quantidade de chumbo 5 vezes maior nos animais Pb 60D. Não houve diferenças nas concentrações de zinco e magnésio entre controles e animais expostos a chumbo. Os microelementos mais abundantes detectados nas tibias contralaterais por Microscopia Eletrônica de varredura por EDS/WDS foram cálcio, fósforo, carbono, oxigênio, magnésio, sódio e potássio, não tendo sido detectadas variações semi-quantitativas nestes elementos. O chumbo não foi detectado nem nos grupos controle ou expostos por MEV, e nos molares só foi detectada no grupo exposto como uma deposição extrínseca.Lead is a highly toxic metal that is ubiquitous do to its great usefulness. Exposure to even low levels of lead (which do not cause symptoms of acute poisoning) is associated with cognitive and neurological disorders. Bone is considered the best marker of exposure to lead. Several chemical elements are found in bone, and some of them may have a different concentration or distribution due to exposure to lead. We tested the hypothesis that there are variations in the elements zinc and magnesium in the tibia of animals exposed to lead (being those elements determined by a conventional analytic chemistry technique). It was also tested whether variations in microelements could be detected by semiquantitative microanalysis in tibias of controls and animals exposed to lead. The objective of this project was to determine the concentration of lead in bone (tibia) of animals exposed to lead from pregnancy to day 28 and day 60. Besides lead, zinc and magnesium were also determined. Lead was also determined in whole blood collected at the end of the 2 time points. Quantitative measurements of lead, calcium, zinc and magnesium have been made in solutions obtained by dissolution of the bone by Atomic Absorption Spectrometry using flame or Graphite Furnace. Tibias were analyzed by scanning electron microscopy using the accessories Electron Dispersive Spectroscopy and Wavelength dispersive Spectroscopy for semiquantitative analysis of inorganic elements in the bone and molars of these animals. Lower molars were also analyzed by these means. Male Wistar rats aged 28 and 60 days were used in these study. In both these ages there were animals in the control (C 28D, n = 5 and C 60D, n=12) and lead exposed group (Pb 28D, n = 5 and Pb 60D, n = 17). Lead concentrations found in control groups were close to the detection limit, and there was always statistically significant differences (P <0.0001) when control groups were compared with those exposed to lead. Blood lead of groups Pb 28D and Pb 60D was 8.0 ug/dl (± 1.1) and 7.2 ug/dl (± 0.89), respectively. There was a statistically significant difference between the masses of the tibia (measured in balance and also from the amount of calcium dissolved in solution): C 60D showing 0.86 g (± 0.13 g) and 0.61 g (± 0, 11) of the Pb 60D group (p = 0.0004). Lead concentrations increased five times when the Pb 28D group was compared with the Pb 60D (8.02 and 43.3 ug/g)(p<0.0001). Zinc concentrations were not different in the C 60D (0.22 mg/g) and in the Pb 60D group (0.22 mg/g)(p>0.05). Magnesium concentrations were 4.89 mg/g in the C 60D and 4.98 mg/g in the Pb 60D (p>0.05). The most abundant trace elements detected in the contralateral tibiae by SEM-EDS/WDS were calcium, phosphorus, carbon, oxygen, magnesium, sodium and potassium and no variations in these elements were detected between the control and lead exposed groups. Lead was detected only in the cervical region of molar teeth of the lead exposed groups by SEM-EDS. This finding revealed lead in the lead oxide (extrinsic deposition) which may be useful for forensic purposes or for determining unknown contaminations. Conclusions: There was a statistically significant difference between the bone masses of the Pb 60D and C 60D groups. While there is no difference between lead concentrations in whole blood of animals 28 and 60 days, the amount of lead was 5 times higher in animals Pb 60D. There were no differences in the concentrations of zinc and magnesium between controls and lead exposed animals. The most abundant trace elements detected in the contralateral tibiae by SEM-EDS/WDS were calcium, phosphorus, carbon, oxygen, magnesium, sodium and potassium, and no semi-quantitative variations in these elements were detected in relation to exposure to lead. Lead was not detected either in control or exposed groups by SEM, and in molars it was only detected in the exposed group as an extrinsic deposition.

Active technology in database management systems (DBMS) enables the movement of behaviour dependent on the system’s state, from the application software to a rule base in the DBMS. With active technology in database systems, the problem of how to design active behaviour has become an important issue. Modelling processes do not foresee support for design of active rules which can lead to conflicts between the event-condition-action (ECA) rules representing the active behaviour and the application systems, using the active DBMS. The unified modelling language (UML) is a widely used notation language and is the main subject in this project. Its features will be investigated to acknowledge to what extend UML modelling diagrams provide information that can be used to formulate ECA rules.
To achieve this, two methods where developed. One of the methods was applied on use-case UML modelling diagrams. The use-case models were developed by means of reflecting a real-life organisation. The results from applying the method on the use-case models were that there are features in UML that can be expressed with ECA rules.

In a biofeedback system, data about the user’s physiological functions is measured and used as input for the system. EDA is a measurement of a persons stress and it is used in biofeedback systems. This essay is about measuring EDA with the Affectiva Q Sensor in the game Tetris. The relationship between EDA and the difficulty in the game has been analyzed, both through correlation analysis and curve fitting. In the game the difficulty can be controlled by implicit and explicit biofeedback, and this functionality has been used to see if users could learn to control their stress through explicit biofeedback. The result of the study was that there exists a corrrelation (the average correlation coefficient was 0.472) between EDA and difficulty. It was also shown that the players could not control their EDA with the help of explicit biofeedbackI biofeedback-system mäts och registreras data om användarens fysiologiska funktioner, för sedan kunna användas som indata till systemet. EDA är ett mått på hur stressad en person är och används i biofeedback-system. Denna uppsats handlar om att mäta EDA med hjälp av Affectiva Q Sensor i spelet Tetris. Sambandet mellan EDA och svårighetsgraden i spelet har undersökts, både med hjälp korrelationsanalys och kurvanpassning. I spelet kan svårighetsgraden styras med implicit och explicit biofeedback, och med denna funktionalitet har det testats det om det är möjligt för en spelare att kontrollera sin EDA med hjälp av den explicita feedbacken. Resultatet var att det finns en korrelation (medelvärdet för korrelationskoefficienten var 0.472) mellan EDA och svårighetsgrad, däremot kunde spelarna inte lära sig att kontrollera sin EDA (stress) när de spelade Tetris.

Full textAbstract:
Sox2, a HMG box transcription factor, is well known for its role in stem cell maintenance, iPS (induced pluripotent stem cell) induction, and development of neural tissues such as central nervous system and sensory organs. Sox2 has been demonstrated to be essential for the development of inner ear sensory patches. It has been shown that Sox2 is under the regulation of multiple regulatory elements to obtain a tissue specific manner.
Two allelic mouse mutants, yellow submarine (Ysb) and Light coat and circling (Lcc) show hearing and balance impairments with different severity. They were made by random insertions of a transgene (pAA2) and X-ray irradiation respectively. Ysb and Lcc are both localized to chromosome 3 and involve complex chromosomal rearrangements. The Sox2 coding region is intact in the mutants, while the Sox2 expression in the otocyst is greatly reduced in Ysb and totally lost in Lcc, which indicates the tissue specific reduction of Sox2 may be due to the rearrangement of Sox2 regulatory element(s). Since Sox2 null mutants die before implantation, the two Sox2 inner ear mutants are valuable models for studying Sox2 knock down (Ysb) and Sox2 knock out (Lcc) condition in the inner ear. To understand the molecular basis behind Sox2 regulation in the inner ear, this project aims to identify the Sox2 otic regulatory elements, and potential Sox2 downstream targets involved in the development of inner ear.
Previous work has indicated that Nop1 and Nop2 are the otic specific regulatory elements of Sox2 in chicken ear. In this project, transgenic mice were generated using Nop1-Nop2, and the result showed Nop1-Nop2 could drive Sox2 expression to the dorsal side of the otiv vesicle, which is different from the endogenous Sox2 expression pattern. Therefore, Nop1 and Nop2 may require other regulatory element(s) to gain a correct regulatory pattern. BAC(RP23-335P23), which contained the DNA sequences close to Ysb integration site 1 was also been tested in transgenic mice. Interestingly, the result showed that BAC(RP23-335P23) could drive Sox2 expression to the ventral side of the otic vesicle, indicating that this BAC may contain the Sox2 otic regulatory element(s).
In this project, the binding relationship between Sox2 protein and Math1 enhancer has also been identified using chromatin immunoprecipitation (Ch-IP). Results showed that Sox2 could bind to Math1 enhancer A in the inner ear cochlea. So Sox2 may regulate Math1 through binding to Math1 enhancer A in inner ear development.
Using a bioinformatics approach, potential Sox2 target genes in inner ear development have been identified from public microarray data on E9 to E15 inner ear tissue by the presence of conserved Sox2 binding sites. Among these potential targets, 4 genes (Itga6, Erbb3, Sox10 and Mycn) have been selected based on their known functions. Their expression patterns in the cochlea of wild type, Ysb and Lcc were verified. The identification of Sox2 downstream target genes using a bioinformatics approach will help us to understand the molecular basis of Sox2 regulation, and also understand the role of Sox2 in the inner ear development.published_or_final_version

Full textAbstract:
The development of a spatial audio ear trainer has been proposed and investigated. A review of the relevant literature has shown that although numerous researchers have simulated spatial characteristics of sound, the devised simulation algorithms were not (properly) verified with respect to their intended subjective effects, thus making them unsuitable for training purposes. Additionally, whilst various timbral ear-training systems have been set up, there is none for spatial quality. To address these shortcomings four spatial attributes of reproduced sound have been considered: source distance, source width, ensemble width and ensemble depth. For each attribute a processing algorithm was developed that allowed highly controlled changes in the respective percept. Using these algorithms four sets of stimuli were carefully generated with the aim of achieving unidimensional variation in terms of the qualities of interest. In order to allow detailed and reliable validation of the simulations' auditory effects, a sensory evaluation strategy was devised that relies on Multidimensional Scaling techniques and the elicitation of supplementary qualitative data as a means of obtaining a complete sensory profile of a group of stimuli. With the help of this methodology as well as critical listening panels the psychological structures of the sound excerpts were measured. Results showed that the envisaged unidimensionality of the source distance, ensemble width and ensemble depth samples was accomplished. As to the source width simulation, results were not as clear-cut, which was attributed to listener unfamiliarity with this perceptual construct and greater stimulus uncertainty. Nevertheless, the analyses unfolded only one major dimension, which is why all four attribute simulations were deemed suitable for the proposed training purposes.

This dissertation provides an analysis of the phenomenon of musical imagery, or the internal 'hearing' of music. I uphold the view that musical imagery, as a kind of auditory imagery, is a kind of sensory or perceptual imagination, and cannot be incorporated into a propositional model of imagination. I further argue that musical imagery differs in important respects both from visual imagery and from other types of auditory imagery, such as inner speech. For this reason, this project makes a contribution to what would be a larger project (not necessarily carried out by a single researcher) of analyzing the sensory or perceptual imagination through careful comparative work in each sensory modality and their various combinations. Chapter 1 provides the background on theories of imagination necessary in order to make this argument, and demonstrates the lack of attention currently paid to auditory imagination in general and musical imagination in particular. The analysis of musical imagery then proceeds from three points of view: phenomenological, conceptual or analytical, and empirical. The goal of Chapter 2 is to describe our subjective experiences of musical imagery. While this description is a description of the phenomenological aspects of our experiences, it is not an example of work in phenomenology proper, as practiced by the followers of Husserl, Sartre, Merleau-Ponty or Heidegger. Rather, the method is necessarily first person, but appeals to the idea that musical imagery experiences occur along a spectrum of possible abilities. That is, while there is too much variation among reports of subjective musical imagery, it still makes sense to appeal to a kind of normal imaginative experience, and, as a result, the reliance on introspection does not result in hopeless idiosyncrasies. Chapter 3 discusses four topics related to content of musical imagery. First, I address the question of what makes auditory imagination specifically auditory; second, I examine the relationship between auditory imagination and imagining hearing; third, I address questions about the ontology of sounds and the ontology of music in the context of my claims about auditory imagination; finally, I discuss whether the contents of musical imagery, as a type of auditory imagination, should be thought of as conceptual or nonconceptual. Chapter 4 addresses the question of the ontology of the mental image, discussed both by Gilbert Ryle and by participants in the mental imagery debate in the field of psychology. Having demonstrated that scientific inquiry into the mechanisms of mental imagery does not involve commitment to ontologically problematic mental entities, I then survey empirical work in cognitive psychology and neuroscience that sheds light on the neural underpinnings of musical imagery. By way of conclusion, I discuss methodological issues regarding the integration of historical, empirical, conceptual, and phenomenological I use to develop a theory of musical imagery as sensory imagination.

Abstract : Technological evolution demands that people keep searching for new forms of knowledge in order to stay updated. Thus, training courses are designed aiming at specific audiences. Distance Learning is an alternative approach to training as well as an improvement in the professional realm. This study aims to present a DL training course as a case study, the Project e-Nova- Network Training Program: Cycle for the Development of Innovations. This research aims to identify the knowledge retention capacity of students through the theories studied throughout the course, the intention is to get students to develop innovation projects, linking this theory to the practice of each student. To meet this objective, it was necessary to determine the constructs that should be studied which are relevant to the subject of this inquiry, it would still be necessary to define a template based on course content and in learning theories. Therefore it was necessary to establish the evaluation criteria within the parameters established by the research, and finally the development of innovative products or processes. The methodological procedures used were applied exploratory research, literature and document research, using mixed qualitative and quantitative methods, being it a participatory action research, which is characterized as a case study. As for the results achieved through this research, it can be concluded that the final projects that met the greatest number of criteria, were the students who also obtained greater knowledge retention of the subjects studied throughout the entire duration of the training course.

Um dos grandes desafios para a educação em todos os níveis de ensino é garantir a permanência dos alunos até o fim do processo formativo. A diferença entre o número de alunos ingressantes e diplomados pode ser definida como evasão. Integrados a esse cenário encontram-se os cursos de graduação ofertados a distância pela Universidade Federal de Santa Catarina - UFSC, que contabilizaram um total 37.114 matrículas (2005 a 2014), das quais 2.260 resultaram em títulos conferidos no mesmo período. Diante desse cenário, o presente estudo possui como objetivo propor modelos estatísticos preditivos para a gestão da evasão dos cursos de graduação ofertados a distância pela UFSC. Para isso, foi realizada uma pesquisa descritiva, de abordagem quantitativa e natureza aplicada a partir de um estudo de caso nos cursos de graduação a distância de Administração, Administração Pública, Letras Espanhol e Matemática. O levantamento dos dados foi realizado a partir dos sistemas institucionais da Universidade. Com base nos dados levantados, utilizando-se do método de Regressão Logística Binária, foram identificadas as variáveis que influenciam na evasão de cada curso, bem como foram desenvolvidos os modelos estatísticos preditivos com base nessas variáveis. Ao final do estudo, foi possível identificar que as variáveis que são significativas para explicar a evasão nos cursos são: o Índice de Aproveitamento Acumulado IAA (todos os cursos), a pontuação do aluno no vestibular (Administração), o fato do aluno residir ou não na cidade do polo (Administração) e a idade dos estudantes (Letras Espanhol). Quanto ao efeito dessas variáveis no fenômeno estudado, observou-se que, a cada um ponto a mais no IAA, a chance de evasão no curso de Administração é reduzida em aproximadamente dez vezes. Nos demais cursos, com esse aumento no Índice a chance de evasão também é reduzida: quatro vezes no curso de Administração Pública, doze vezes para Letras Espanhol e cinco vezes para Matemática. Ainda, identificou-se que um ponto a mais no vestibular aumenta 86% a chance do aluno evadir; residir na cidade do polo aumenta 131% a chance evasão; e a cada um ano a mais de idade, a chance de evasão aumenta 6,8%. Ao aplicar os dados dos alunos ativos nos cursos aos respectivos modelos, observou-se que 71% dos alunos do curso de Administração e 100% de Matemática possuem probabilidades superiores a 50% de evadir. Já para os cursos de Administração Pública e Letras Espanhol, 57% e 70,3% dos alunos possuem probabilidades de evasão até 50%.
Abstract: One of the major challenges for education at all its levels is to ensure the permanence of students until the end of the training process. The difference between the number of incoming and graduate students can be defined as dropout. In this scenario are the undergraduate e-learning courses from the Universidade Federal de Santa Catarina - UFSC, which accounted for a total of 37.114 (between 2005 and 2014) enrollment, of which 2.260 resulted in degrees achieved in the same period. This study aims to propose predictive statistical models for the drop out management in undergraduate e-learning courses offered by UFSC. A descriptive research was carried out, with a quantitative approach and applied nature, based on a case study of e-learning courses in Business, Public Administration, Spanish Language and Literature and Mathematics. The data collection was carried out from the institutional systems of the University. Based on the data collected, using the Binary Logistic Regression method, it was identified the variables that influence the drop out of each course, as well as the statistical predictive models were developed based on these variables. At the end of the study, it was possible to identify that the significant variables to explain drop out in the courses are: Performance index - IAA (all courses), student's score in the university entrance examination (Business), residing or not in the city where the support polo is located (Business) and the age of the students (Spanish Language and Literature). Regarding the effect of these variables on the phenomenon studied, it was observed that, at each point in the IAA, the chance of drop out in the course of Business is reduced approximately ten times. In other courses, with the same increase in the Index, the chance of avoidance is also reduced: four times in the Public Administration course, twelve times for Spanish Language and Literature and five times for Mathematics. Also, it was identified that an additional point in the entrance examination increases the student's odds to evade by 86%; Residing in the city where the support the polo is located increases 131% the odds to drop out; And for each one year of age, the odds of evasion increases by 6,8%. Applying the data of the active students in the respective models developed, it was observed that 71% of the students of the course in Business and 100% of Mathematics have probabilities of drop out higher than 50%. About the courses of Public Administration and Spanish Language and Literature, 57% and 70,3% of the students have probability of drop out up to 50%.

Full textAbstract:
Ideation, the selection and arrangement of information to build a
text, though a necessary skill for tertiary students, is not
satisfactorily addressed in writing skills textbooks for English as a
Second Language/English for Academic Purposes. To develop a
pedagogical approach to ideation, teachers need a theory of
language. The most fruitful theory is systemic-functional
linguistics, but systemic-functional theory has not yet fully
developed a theory of ideation. A related theory, Rhetorical
Structure Theory, offers a useful tool to analyse ideation both in
well formed model texts and, with slight modification, in not well
formed student texts. With Rhetorical Structure Theory, the
analyst can separate semantic value from syntax. The resulting
analysis indicates with clarity certain problem areas in ideation
which teachers need to address. Teachers are thus better equipped
to devise teaching approaches to address ideation in the classroom.
