Full textAbstract:
In this dissertation, a novel unified development framework is developed to support multi-systems design, visualization, and integration for Human Machine Interface (HMI) and physical embedded agents, and real-time vision system. We address the open source and platform-independent software architecture, system integration, and communication infrastructures to support rapid design and realization. The proposed strategy is based on the new abstract visual modeling and automatic code generation technique for a class of Cyber Physical System (CPS). Unlike middleware integration approach, the new unified development framework supports the developer's needs by realizing a platform independent development methodology that bases on the model orientation paradigm. It captures the important characteristics of HMI and embedded system domain in abstract and reusable models. The system communication between each application domain is seamless in design perspective. Moreover, it allows multiple communication design flows to be embedded inside a single design diagram. The proposed development framework has the following properties. a) Multi-domain software design and integration framework for HMI system, embedded system, and real-time vision system b) Open source software framework c) New abstract visual modeling technique for unified HMI, embedded agent and vision framework d) Multi-communication infrastructure e) Platform-independent architecture Four different CPS application examples have been carried to verify the performance of the proposed design framework. These include: 1. Telecontrol of robotic system for biomedicine application 2. Real-time supervisory control of mobile robotic system and optimal path planning 3. System analysis, design, and integration for legacy subsystem 4. System analysis, design, and integration for real-time traffic sign detection

Full textAbstract:
This research investigated how meanings associated with race, gender, and class relations in New Zealand mainstream schools are produced, reproduced, and challenged within the arenas of school sport, physical education, and physical activity. The study focused specifically on Maori girls� and young Maori women�s experiences in these arenas in order to determine how race, gender, and class identities interact, and also provided Maori girls and young women with an opportunity to be heard in research. The effects of historical and contemporary discourses, polices, and practices in New Zealand sport and school were reviewed. Theoretical perspectives and methodologies such as critical theory, kaupapa Maori research, feminism, postmodernism, and cultural studies informed the research. Qualitative methods of study such as critical ethnography, document analysis, participant observation, semi-structured interviews, and self-reflective diaries were used in order to observe, investigate, and empower the Maori girls and women, teachers, and the school involved. By utilising social reproduction concepts such as hegemony (Gramsci), discourse (Foucault), and cultural capital (Bourdieu), initiatives in schools that related to Maori girls and young women were investigated at three different levels; the fantasy discourse level, the implementation level, and the reality discourse level. The many identities and ideologies of those involved in the transformation from fantasy to reality had an effect on what was ultimately produced, reproduced, and challenged. These were also implicit and explicit ideologies operating in school sport, physical education, and physical activity arenas that worked to reproduce gendered dualisms, racial stereotypes, and class differentiation. By focusing on power relations at the structural and personal level, instances where Maori girls and young women practised �power over� others, or the �power to act� were discussed. Maori concepts such as whakaiti, whakamaa, whakahiihii, tautoko, aawhina, and manaaki, as well as more colloquial terms such as being hungus, hori, and hoha highlighted the attitudes, values, beliefs and behaviours of participants involved in the study and were used to inform the different levels of analysis. Difficulties in closing the gap between what was hoped for and what actually happened were discussed, and political and practical implications were suggested.

Full textAbstract:
This document describes studies of two independent regions of the interstellar medium (ISM). These studies have the common element that both pertain to regions in our Galaxy that are known to be associated with present-day star formation. These studies aim to help us understand the ISM, star formation, and ultimately where we came from, since, after all, our star, the Sun, is itself the product of star formation 4.5 billion years ago. The first project measured the Zeeman Effect on the 21 cm H I absorption line in order to create a map of the line of sight magnetic fields near a star forming region called W3. From the map of the field, it was possible to create a three dimensional model of the magnetic field morphology. Also, calculating the various energies associated with W3 revealed that it is most likely in virial equilibrium, not expanding or contracting.
The second project used an instrument on the Hubble Space Telescope (HST) to measure the abundance of iron in a neutral region near the Orion Nebula called Orion’s Veil. One of the goals of this project is to investigate whether solid dust grains can be destroyed by ionizing radiation by comparing the amount of solid iron in Orion’s Veil to the amount in the nearby ionized regions. By measuring the depletion of iron in the neutral Veil and comparing it to the depletion of iron the H+ regions of the Orion Nebula, it was possible to conclude that iron was not being released into the gas phase by ultraviolet photons. In addition, oscillator strengths for two Fe II transitions were measured.

Full textAbstract:
This thesis focuses on defining a set of design strategies to develop and assess video games that foster physical activity, commonly referred to as exergames. Regular physical activity is essential for a good development of children and exergames have the potential to be used as an adherent and fun tool. This should result in more healthy children and compensate for the current lack of physical activity due to sedentary behaviors.
This thesis focuses both on quantity as well as quality of physical activity. Concerning quantity, we focus on aerobic activity, while quality refers to richness and diversity of movement within conditional and coordinative capacities.
This thesis is a first step to design exergames as public health tools by bridging the notions of playability and efficacy of exergames. We define an interdisciplinary protocol to design multiplayer exergames in collaboration with physical activity experts. A parameter, the Interaction Tempo, and evaluation methods to control the amount of physical activity are presented and validated. We provide strategies to achieve the aforementioned quality of physical activity in exergames and a robust evaluation method to assess it during a play session. We finally explore the influence and limitations that the body attitude can have on the intensity and affective state.Aquesta tesi se centra en la definició d'un conjunt d'estratègies de disseny per a desenvolupar i avaluar els videojocs que fomenten l'activitat física, comunament coneguts com a exergames. L'activitat física regular és essencial per a un bon desenvolupament dels nens i els exergames tenen el potencial de ser utilitzats com una eina divertida i que fomenti l'adhesió al programa d'exercici. Això ha de resultar en nens més sans i compensar l'actual falta d'activitat física a causa dels comportaments sedentaris. Aquesta tesi es focalitza tant en la quantitat com en la qualitat de l'activitat física. Per al que fa a la quantitat, ens centrem en l'activitat aeròbica, mentre que la qualitat es refereix a la riquesa i diversitat del moviment dins de les capacitats condicionals i coordinatives. Aquesta tesi és un primer pas per dissenyar exergames com a eines de salut pública a través de crear una relació entre les nocions de jugabilitat i l'eficàcia dels exergames. Definim un protocol interdisciplinari per a dissenyar exergames multi jugador en col•laboració amb experts en activitat física. Es presenta i valida el Tempo d'Interacció, un paràmetre per a controlar la quantitat d'activitat física, com també mètodes d'avaluació d'aquesta. Proporcionem estratègies per aconseguir la qualitat, abans esmentada, de l'activitat física en exergames i un mètode d'avaluació sòlida per a avaluar-la durant una sessió de joc. Finalment explorem la influència i limitacions que l'actitud del cos pot tenir sobre la intensitat i estat afectiu.

Full textAbstract:
Robots and virtual agents grow rapidly in behavioural sophistication and complexity. They become better learners and teachers, cooperators and communicators, workers and companions. These artefacts – whose behaviours are not always readily understood by human intuition nor comprehensibly explained in terms of mechanism – will have to interact socially. Moving beyond artificial rational systems to artificial social systems means having to engage with fundamental questions about agenthood, sociality, intelligence, and the relationship between mind and body. It also means having to revise our theories about these things in the course of continuously assessing the social sufficiency of existing artificial social agents. The present thesis presents an empirical study investigating the social influence of physical versus virtual embodiment on people's decisions in the context of a bargaining task. The results indicate that agent embodiment did not affect the social influence of the agent or the extent to which it was perceived as a social actor. However, participants' perception of the agent as a social actor did influence their decisions. This suggests that experimental results from studies comparing different robot embodiments should not be over-generalised beyond the particular task domain in which the studied interactions took place.

Costa, Allison Hainline. "A study of magnetic fields in HII regions using Faraday rotation." Diss., University of Iowa, 2018. https://ir.uiowa.edu/etd/6085.
Full textAbstract:
Massive young stars dynamically modify their surroundings, altering their stellar nurseries and the gas that exists between stars. With my research, I assess the modification of the Galactic magnetic field within HII regions and stellar bubbles associated with OB stars. Because HII regions are plasmas, magnetic fields should be important to the dynamics of the region. Understanding how the magnetic field is modified in these structures is critical for inputs to simulations and for assessing stellar feedback. To obtain information on the properties of the magnetic field, I measure the Faraday rotation of linearly polarized radio waves that pass through the plasma of the HII region.
In this thesis, I present results of Faraday rotation studies of two Galactic \HII regions. The first is the Rosette Nebula (l = 206 deg, b = -1.2 deg), and the second is IC 1805 (l = 135 deg, b = 0.9 deg), which is associated with the W4 Superbubble. I measure positive rotation measure (RM) values in excess of +40 to +1200 rad m^-2 due to the shell of the Rosette nebula and a background RM of +147 rad m^-2 due to the general interstellar medium in this area of the Galactic plane. In the area of IC 1805, I measure negative RM values between +600 and --800 rad m^-2 due to the HII region. The sign of the RM across each HII region is consistent with the expected polarity of the large-scale Galactic magnetic field that follows the Perseus spiral arm in the clockwise direction, as suggested by Van Eck et al. (2011, ApJ, 728, 14).
I find that the Rosette Nebula and IC 1805 constitute a "Faraday rotation anomaly", or a region of increased RM relative to the general Galactic background value. Although the RM observed on lines of sight through the region vary substantially, the |RM| due to the nebula is commonly 100 -- 1000 rad m^-2. In spite of this, the observed RMs are not as large as simple, analytic models of magnetic field amplification in HII regions (such as by magnetic flux conservation in a swept-up shell) might indicate. This suggests that the Galactic field is not increased by a substantial factor within the ionized gas in an HII region. Finally, these results show intriguing indications that some of the largest values of |RM| occur for lines of sight that pass outside the fully ionized shell of the IC 1805 HII region, but pass through the Photodissociation Region (PDR) associated with IC 1805.

Anderson, Zann Benjamin. "Laying a Foundation for Computing in Outdoor Recreation." BYU ScholarsArchive, 2019. https://scholarsarchive.byu.edu/etd/8713.
Full textAbstract:
Mobile computing allows individuals to bring computing with them into the outdoors. This creates a new situation in which individuals can stay connected even when trying to "get away from it all." Questions arise from this juxtaposition regarding whether the inclusion of computing in these activities is a positive or a negative. Evidence exists supporting both conclusions. We posit that computing can contribute positively to outdoor recreation without distracting. This dissertation details work undertaken in two phases which explores how computing can accomplish this goal. Phase 1 explored how individuals are already using computing technology in hiking, and culminated with the development of a model describing individuals' decisions regarding technology use on the trail. In Phase 2, we developed a vision which navigates the tension between the connection technology provides to our day-to-day lives and the desire to disconnect, along with prototypes which serve as an embodiment of this vision. We found that computing is in wide use by hikers, and through qualitative data analysis we developed a Two Worlds model which describes their decisions regarding technology use when hiking. This model provides a space which can be probed and explored in future work. Our vision guides careful growth in the inclusion of computing in outdoor recreation, allowing computing to support activities without becoming a distraction. Our work makes important empirical, theoretical, and artifact contributions to the field of HCI. It also identifies interesting areas of exploration, some of which have already informed the development of our Two Worlds model, and some of which remain largely unexplored. In this sense, our work has both blazed new trails in exploring computing's place in outdoor recreation and identified "side trails" for further exploration by ourselves and others. We look forward to this work and its results.

Full textAbstract:
The importance of office physical layout has never been studied by scholars andentrepreneurs from the perspective of managing human resources in project-basedorganizations (PBOs) from a managerial perspective. This paper believes that officephysical layout has great influence on organizations’ working efficiency in PBOs. Withthe increase of PBOs, it requires a new context for human resource management (HRM).The paper mainly focuses on the impact of office physical layout on communication andinnovation in PBOs. In the literature review part, the paper collects together relevantresearches, experiments, and theoretical studies on physical layout, PBOs,communication and innovation, and finds out the gaps between the empirical situationsand current theoretical studies. Moreover, the relations between office physical layout,communications, innovation and organizational competitive advantage will be explored.The discussions and analysis are based on the premise that if people can maximize theopportunity of communication in PBOs through office physical layout, the possibility ofknowledge transfer and knowledge integration, creativity and innovation will also belargely improved. To testify this premise, we spent five months research time andfocused on four companies in Sweden and took interviews with their senior managers.The paper also does comparisons with the office physical layout in PBOs and in otherorganizations to find out whether organization’s natures will influence its working waysand their office physical layout. The implications of the work for both future researchand practice are taken into our considerations. The result of this research shows officephysical layout indeed has great impact on employees’ communication, innovation andworking efficiency. However, different organizations should take into their empiricalconditions into consideration when designing their office physical layout.

Full textAbstract:
Objective. To determine the relationship between overall psychological well-being and stress on diet quality among young adult women and to examine the potential confounding influence of season, physical activity and sleep on these relationships. Design/Participants. The study used a cross-sectional design. Three hundred and fifty-one women were recruited to participate in the study. All participants were university students (20.2 ± 1.6 y). Overall psychological well-being was assessed using the General Well-being Schedule (GWB) and the Perceived Stress Scale (PSS). Diet intake was measured using three 24-hour recalls over a seven day period. The Healthy Eating Index (HEI) was calculated to assess diet quality. Physical activity (PA) and sleep were both measured objectively using accelerometers over seven consecutive days. Season of assessment was also included as a covariate. Results. The average HEI score was 59.3 ± 12.5 out of 100 and is classified as "Needs Improvement." The average GWB score was 72.8 ± 13.1 out of 110 which is on the border between "moderate distress" (61 to 72) and "positive wellbeing" (73 to 110). Significant relationships were seen with specific aspects of psychological well-being, however global psychological well-being as measured by the General Well-being schedule was not related to any measure of diet quality. Chronic stress was related to low adherence to dietary guidelines (F = 11.46 and p = 0.0008). Chronic stress was also related to low consumption of fruits and vegetables (F = 5.03, p = 0.0256). Feeling in control of emotions and behaviors was related to low consumption of non-nutrient dense foods (NNDF) (F = 3.33, p = 0.0198). Controlling for PA and sleep time reduced the magnitude of all of these relationships between 11% and 42%. Results from the PSS were positively related to the consumption of NNDF (F = 3.97, p = 0.0472). Controlling for PA and sleep time increased the magnitude of this relationship by 34%. Season had a negligible impact on any of the relationships between psychological well-being and any measure of diet quality. Conclusion. Subscales of psychological well-being such as chronic stress, acute stress, emotional behavioral control, and depression were related to diet quality. While these observed relationships were independent of the influence of season, physical activity and sleep, controlling for these variables had a moderating effect.

Full textAbstract:
The prevalent visions of ambient intelligence leverage natural interactions between users and available services in a smart space. In recent years, we have seen a huge interest from industry and academia in using handheld devices to interact with things, places and people in the real world. To facilitate such interactions, things are usually annotated with RFID tags or visual markers. These tags or markers are read by a handheld device equipped with an integrated RFID reader or a camera, in order to fetch related information and initiate further actions. Interacting with the Internet of Things (IoT) in a real environment has become increasingly desirable and feasible. This thesis contributes to the domain of physical interactions with IoT; however, we use a spatial-geometric approach instead of RFID or marker based solutions. Using this approach, for example, a user can point his/her handheld device to an annotated thing, from a distance, for the purpose of interaction. The pointing direction and location is determined based on the fusion of the mobile position and of the accelerometer data of the handheld device. To annotate things, their geometric coordinates are specified and related information or services are associated to them. In this thesis, we present a comprehensive and extensible framework to integrate various physical interactions with IoT into multimedia applications. The framework supports the implementations of pointMe, touchMe, and context-aware based interactions with geometrically annotated IoT. We define specific methods and practices that can be incorporated in order to build the interactions. We realize smart home, atlas learning, presentation interaction, smart haptic interaction, and learning based video interaction game prototypes in order to perform experiments and demonstrate the applicability and potential of the proposed geometric based annotation approach. In the analysis of the interaction techniques of the prototypes, we present the advantages and disadvantages of the geometric based annotation of IoT as seen by potential users, in comparison to RFID tags or visual markers based approaches.

Full textAbstract:
The aim in this study was to develop a model for the probability of finding active golden eagle nests during their breeding season. It was done by using environmental variables derived from expert models which were tested against empirical data. This resulted in a habitat suitability index (HSI), which in this case is assumed to indicate the probability of active nests of golden eagles. The study was conducted together with the County Administrative Board of Västernorrland with the purpose to improve golden eagle’s ecological status.To develop the model, different combinations of several explanatory variables were tested in a model selection process, where the most optimal and parsimonious model was chosen. The tested variables have earlier been shown to affect golden eagles, as slope, aspect, forest age, foraging habitat, suitable flight routes, human population density, roads, railways, power lines, wind power plants, hiking trails and clear cuts. The variables where applied in in ArcMAP at three different scales: nest scale (25 x 25 meter), proximate scale (a circle with the radius of 500 meter) and home range scale (a circle with the radius of 8253 meter). A preliminary test of the variables showed that all golden eagle nests were found in slopes with at least 5֯ degreesas well as in home ranges with human population density not more than 8 people/km2. Due to that a stratified analysis wasperformed. The variables where analysed by multiple logistic regression in R, where the occurrence of golden eagles’ nestswas compared towards random points in the landscape. All variables were also tested one by one by logistic regression. Afterperforming the multiple logistic regression, it was possible to apply its equation into ArcMap to obtain suitability maps withHSI values over Västernorrland’s county.The comparisons of different models show that it is better to combine different spatial scales in the model than only using one spatial scale. The result indicate that three different models might be the best, which all had different combinations of slope and aspect at nest scale and power lines at the proximate scale. Two of these models also include hiking trails and human population density, both at home range scale, in their equation. Since it was some unclarity about the causality between hiking trails and human population density, the conclusion was not to choose any of these as the final model. The final model was more parsimonious and had an additive effect from slope and southern aspect at the nest scale and an antagonistic effect from power lines at the proximate scale.This study clarifies that golden eagles’ habitat preferences for nesting sites during their breeding period is steep slopes (at minimum 5֯ degrees) in more southern aspects with few power lines in the proximate area surrounding the nest. Their homeranges are also situated in areas with less than 8 people/km2. The study also pinpoints a potential conflict between golden eagleand wind power planning, as golden eagles prefer steep slopes and remote areas, which also are valuable areas for wind powerplants. Golden eagles’ preference of remote areas also indicate that they might be affected by human persecution, why certainconservation effort should be focused into this issue. Out from the final model, you can find cluster in the landscape where youcan focus conservation management and restrict exploitation. Due to low number of wind power plants in the landscape, nothingcould be concluded about their effect on golden eagle in this study. An advice from the golden eagle’s perspective is to use theprecautionary principle and further plan wind power plants in areas which already have high disturbance, as for example closeto power lines or roads. The result also indicates that forest age from SLU Forest Map is not suitable for telling where to findgolden eagle nests. GIS-data over forest age would facilitate conservation management for plenty of species connected to theforest.Although good statistical results for the final model, cautions need to be taken in general, since neither population viability analysis have been included, nor changes over time in the landscape. Another issue is the low sample size, where a larger sample size would make it possible to perform profound calibration and validation of the data. To develop a more robust model, the advice is to include these into the model and use a larger sample size.

Full textAbstract:
Four regions of massive star formation in the Large Magellanic Cloud (LMC) were observed for water and methanol maser emission and radio continuum emission. A total of 42 radio detections were made including 27 new radio sources, four water masers, and eight compact HII regions. The lobes of a radio galaxy were resolved for the first time, and the host galaxy identified. Seven sources were associated with known massive young stellar objects (YSOs). A multi-wavelength analysis using both the infrared and radio spectrum was used to characterize the sources. Mid-infrared color-magnitude selection criteria for ultracompact HII (UCHII) regions in the LMC are presented, yielding 136 UCHII region candidates throughout that galaxy. New maser detections identified two previously unknown massive YSOs. No methanol masers were detected, consistent with previous studies and supporting the hypothesis that the LMC may be deficient in these molecules. These discoveries contribute to the history of star formation in the LMC, which will lead to a better understanding of star formation in the Milky Way and throughout the universe.

Full textAbstract:
Le satellite Planck, dont le lancement est prévu en 2007, constituera la troisième génération d'instruments dédiés à l'observation de l'anisotropie du corps noir cosmologique, avec une sensibilité environ 600 fois meilleure que COBE. C'est grâce à l'évolution des technologies instrumentales au niveau des détecteurs bolométriques, de la cryogénie et de l'électronique à faible bruit que cette avancée considérable est possible. Une mesure aussi sensible demande la maîtrise de plusieurs aspects intimement liés: l'acquisition de signaux bas niveau, la production et la maîtrise des basses températures, le contrôle du rayonnement parasite et la stabilité de la mesure. Ce mémoire traite des relations entre ces différents aspects mais aussi des avancées technologiques auxquelles j'ai contribué dans chacun de ces domaines. Les deux premiers chapitres sont consacrés à la description d'une part du contexte scientifique et d'autre part du satellite Planck et de l'instrument HFI (High Frequency Instrument). Le troisième chapitre expose la mise au point et l'utilisation du cryostat Symbol qui m'a permis de tester et de valider des solutions techniques pour HFI. Le quatrième chapitre concerne la chaîne de détection bolométrique et le développement d'un système symétrique pour HFI. Le problème de la lumière parasite est traité en chapitre 5 et conduit aux spécifications de stabilité de température des différents étages de Planck-HFI. Ceci m'a ammené à étudier les solutions technologiques permettant d'atteindre ces spécifications au niveau de l'étage 100mK supportant les bolomètres, sujet traité en chapitre 6, alors que le chapitre 7 est consacré à la thermométrie HFI du point de vue de la sensibilité et de la précision. Enfin, le dernier chapitre montre comment ces progrès instrumentaux rendent possible la détection par Planck-HFI de l'effet dipolaire dans le Fond Diffus Extragalactique Sub-millimétrique (FDES) provenant de l'émission intégrée des galaxies qui ne sont pas résolues.

Full textAbstract:
Le thème principal de cette thèse est l'étude d'algorithmes de reconnaissance de cibles non coopératives (NCTR). Il s'agit de faire de la reconnaissance au sein de la classe "chasseur" en utilisant le profil distance. Nous proposons l'étude de quatre algorithmes : un basé sur l'algorithme des KPPV, un sur les méthodes probabilistes et deux sur la logique floue. Une contrainte majeure des algorithmes NCTR est le contrôle du taux d'erreur tout en maximisant le taux de succès. Nous avons pu montrer que les deux premiers algorithmes ne permettait pas de respecter cette contrainte. Nous avons en revanche proposé deux algorithmes basés sur la logique floue qui permettent de respecter cette contrainte. Ceci se fait au détriment du taux de succès (notamment sur les données réelles) pour le premier des deux algorithmes. Cependant la deuxième version de l'algorithme a permis d'augmenter considérablement le taux de succès tout en gardant le contrôle du taux d'erreur. Le principe de cet algorithme est de caractériser, case distance par case distance, l'appartenance à une classe en introduisant notamment des données acquises en chambre sourde. Nous avons également proposé une procédure permettant d'adapter les données acquises en chambre sourde pour une classe donnée à d'autres classes de cibles. La deuxième contrainte forte des algorithmes NCTR est la contrainte du temps réel. Une étude poussée d'une parallélisation de l'algorithme basé sur les KPPV a été réalisée en début de thèse. Cette étude a permis de faire ressortir les points à prendre en compte lors d'une parallélisation sur GPU d'algorithmes NCTR. Les conclusions tirées de cette étude permettront par la suite de paralléliser de manière efficace sur GPU les futurs algorithmes NCTR et notamment ceux proposés dans le cadre de cette thèse.

Full textAbstract:
Traditional SPICE simulation tools and applications of circuit theory lack real-time interaction and feedback. The goal of this thesis was to create an interactive physical environment to allow the manipulation and simulation of discrete electrical components in near-real-time while optimizing and streamlining the human-computer interaction (HCI) elements to make the user experience as positive and transparent as possible. This type of HCI and near-real-time simulation feedback would allow for the instant realization of how the parameters of each discrete component or hardware module affect the overall simulation and response of the circuit.
The scope of this thesis is to research, design and develop two real-time interactive SPICE simulation tools and analyze the real-time benefits and HCI elements of both simulators, principally the user interface design itself. The first real-time interactive simulator (TouchSPICE) uses multiple embedded processors (touchscreen hardware blocks) and a host computer to build and simulate a circuit. The second real-time interactive simulator (ReActive-SPICE) uses a single host computer with integrated software to build and simulate a circuit, much like LTspice™ and PSpice™ without the real-time aspects.
As part of the study, 20 students were asked to create circuits utilized in undergraduate-level labs using TouchSPICE and ReActive-SPICE for the sole purpose of providing feedback on the two user interfaces. Students were asked to complete a survey before, during and after circuit creation to provide a basis for judging the intuitiveness, efficiency and overall effectiveness of the HCIs. Conclusions based-off the surveys support the hypothesis that both TouchSPICE and ReActive-SPICE were more intuitive and overall simpler than traditional SPICE simulation tools. Feedback collected showed TouchSPICE to have a more intuitive user interface while ReActive-SPICE proved to be more efficient. ReActive-SPICE was further developed and enhanced to improve the user interface as well as the overall circuit creation and real-time simulation processes.

Full textAbstract:
Current studies done using a learning test for children have problems as they only make evaluations of Physically and Neurologically Impaired (PNI) children who can succeed in the test and can be considered as a PASS/FAIL test. This pilot study takes a holistic view of cognitive testing of PNI children using a user-test-device triad model and provides a framework using non-PNI children and adults as controls. Comparisons using adapted off-the-shelf novel interfaces to the computer, in particular, an Electroencephalograph (EEG) head-set, an eye-tracker and a head-tracker and a common mouse were carried out. In addition, two novel multi-modal technologies were developed based on the use of brain-waves and eye-tracking as well as head-tracking technologies to support the study. The devices were used on three tests with increasing cognitive complexity. A self-developed measure based on success streaks (consecutive outcomes) was introduced to improve evaluations of PNI children. A theoretical model regarding a fit of ability to devices was initially setup and finally modified to fit the view of the empirical model that emerged from the outcomes of the study. Results suggest that while multi-modal technologies can address weaknesses of the individual component modes, a compromise is made between the user’s ability for multi-tasking between the modes and the benefits of a multi-modal device but the sample size is very small. Results also show children failing a test with a mouse but passing it subsequently when direct communication is used suggesting that a device can affect a test for children who are of a developing age. This study provides a framework for a more meaningful conversation between educational psychologists as well as other professionals and PNI parents because it provides more discrimination of outcomes in cognitive tests for PNI children. The framework provides a vehicle that addresses scientifically the concerns of parents and schools.

Le satellite Planck a été conçu pour mesurer de manière ultime les anisotropies primairesen température du fond diffus cosmologique (CMB), et améliorer les contraintes existantes sursa polarisation. La première partie de cette thèse s'inscrit dans le cadre du traitement des donnéesde l'instrument à haute fréquence de ce satellite. Les propriété statistiques du bruit sonttestée. Des effets systématiques dans l'estimateur du bruit sont ainsi détectés, et certains ontpu être corrigés. La sélection des données à projeter sur les cartes est ensuite présentée, ainsique la validation de la qualité de ces données. Cette sélection est finalement comparée à unesélection pour laquelle les critères sont beaucoup plus sévères, afin de vérifier que l'impactdes données imparfaites résiduelles est négligeable. Nous montrons que les données validéespour une utilisation scientifique répondent bien aux exigences de gaussianité et de stationnarité: des effets instrumentaux ne devraient pas induire de fausses conclusions cosmologiques.La seconde partie porte sur l'interprétation des données ainsi obtenues. Le modèle de concordanceest présenté, ainsi que les résultats rendus publiques par la collaboration Planck en 2013.La troisième partie est dédiée à deux études phénoménologiques concernant l'ionisation del'Univers. Premièrement, l'influence de l'annihilation de matière noire sur le spectre du CMBest étudiée : une méthode pour estimer l'impact de l'incertitude des canaux par lesquels sefont ces dépôts d'énergie est développée.

Full textAbstract:
La cosmologie est une science très ancienne qui a pour but de décrire l'Univers à grande échelle. Le modèle standard de la cosmologie est un modèle de Big-Bang de type CDM inflationaire, il est basé sur la théorie de la Relativité Générale. Le rayonnement fossile constitue l'un des trois piliers de ce modèle, avec l'expansion de l'Univers et la nucléosynthèse primordiale. C'est le rayonnement le plus ancien observable dans l'Univers. L'étude de ses anisotropies de température et en polarisation permettent d'accéder a des informations directes sur le contenu et la géométrie de l'Univers primordial. Le satellite Planck, lancé le 14 mai 2009, représente la troisième génération de missions satellite d'étude du rayonnement fossile. La sensibilité exceptionnelle de ses instruments High Frequency Instrument et Low Frequency Instrument permettra de contraindre très fortement les modèles cosmologiques décrivant les premiers instants de l'Univers, en particulier la période d'inflation, et de mesurer avec une précision de l'ordre du pourcent les paramètres cosmologiques qui décrivent l'évolution de l'Univers. Pour atteindre ces objectifs scientifiques ambitieux chacun des effets systématiques instrumentaux doit être sévèrement contrôlé et corrigé au cours de l'analyse des données. L'effet des rayons cosmiques interagissant avec les bolomètres de HFI, qui est l'un des effets systématiques instrumentaux les plus importants, et l'un des seuls qui diffère significativement des prédictions, est corrigé lors de l'analyse des données ordonnées en temps. La compréhension détaillée de ce phénomène et sa modélisation sont nécessaires pour s'en affranchir et atteindre une sensibilité effective optimale. Elles permettront également de tenir compte de cet effet dans les instruments futurs dès la conception des détecteurs. Cette thèse propose une première partie consacrée à la cosmologie, une seconde partie décrivant le satellite Planck, l'instrument HFI et en particulier ses détecteurs et une troisième partie consacrée à l'analyse des données de l'instrument HFI.

Full textAbstract:
Fundação de Amparo a Pesquisa do Estado de AlagoasEstudos recentes sugerem que a técnica de estimulação elétrica transcraniana (ETCC) pode reduzir a vontade subjetiva de comer e desejo pelo alimento, mostrando-se uma possível ferramenta terapêutica no combate à obesidade. O exercício físico suscita efeitos positivos sobre a manutenção e perda do peso corporal total, balanço energético, regulação do apetite e neuroplasticidade, oxigenação e vascularização cerebral. Desse modo, o objetivo do presente estudo foi verificar o efeito da ETCC, associada à prática de exercício físico, sobre a variabilidade da freqüência cardíaca (VFC) e sensações subjetivas do apetite em humanos obesos. Participaram do estudo nove indivíduos de ambos os sexos. Os sujeitos foram submetidos a duas etapas de procedimentos experimentais. A primeira consistiu na realização de um teste cardiopulmonar máximo no cicloergômetro com protocolo do tipo rampa, a fim de determinar sua capacidade cardiorrespiratória (VO2MAX; FCMAX; CargaMAX). Na segunda etapa, os sujeitos realizaram duas sessões não consecutivas de testes, em que inicialmente permaneceram sentados por 10min, receberam ETCC anódica ou placebo (2mA por 20min), em ordem randomizada e, logo após, executaram sessões isocalóricas (~200kcal) a 70%VO2MAX. Em seguida, permaneceram em recuperação sentados em repouso por 30 minutos. Em todo o protocolo, escalas visuais analógicas para avaliação das sensações subjetivas de apetite, bem como a VFC, foram registradas. Os resultados mostraram que, para os escores médios das sensações de saciedade na condição de ETCC anódica, houve diminuição significativa entre os momentos 30 PÓS EXERCÍCIO vs. todos os momentos analisados (P<0.05). Houve aumento da sensação de fome, em ambas condições de ETCC, entre os momentos 30 PÓS EXERCÍCIO vs. PÓS EXERCÍCIO. No entanto, houve diminuição do desejo pelo alimento após a ETCC anódica (PRÉ ETCC vs. PÓS ETCC; p=0.04), mas não quando os indivíduos receberam ETCC placebo. Quando se associou a ETCC com o exercício, uma diminuição ainda maior foi evidenciada (PRÉ ETCC vs. PÓS EXERCÍCIO; p=0.05). Quanto à VFC, a variável low frequency (LFLOG) demonstrou, em todos os momentos e condições analisados, semelhança em seu comportamento. Por outro lado, as variáveis high frequency (HFLOG) e balanço simpatovagal (LF/HFLOG), apresentaram aumento e diminuição significativas, respectivamente, entre as condições analisadas (placebo e anódica) após a realização da sessão de exercício. Um maior HF e menor LF/HF foram mantidos até o trigésimo minuto de recuperação. Portanto, pode-se concluir que a aplicação da ETCC anódica associada à prática de exercício físico não foi capaz de modificar as respostas hedônicas de fome e saciedade. Porém, a ETCC foi capaz de diminuir o desejo pelo alimento, o que foi potencializado pela associação com o exercício físico. Por outro lado, a ETCC foi capaz de alterar o comportamento do sistema nervoso autonômico cardíaco, propiciando uma maior modulação da atividade parassimpática e diminuição no balanço simpatovagal durante todo o período de recuperação após exercício aeróbio.

Full textAbstract:
Ce travail de thèse porte sur la valorisation de granulats recyclés dans la fabrication de nouveaux liants hydrauliques. Il s’inscrit dans une problématique actuelle de gestion des déchets du BTP, de sauvegarde des ressources naturelles et de réduction des gaz à effets de serre liés à la production de matériaux cimentaires. En quelques chiffres, sur les 260 millions de tonnes de déchets inertes produits annuellement par le secteur du BTP en France, 90 millions sont encore déposés en installations de stockage. C’est ce gisement qu’il convient de réduire pour accentuer la fabrication de granulats recyclés estimée aujourd’hui à 15 millions de tonnes/an. Dans cette perspective, ce travail de recherche a pour double objectif de valoriser des granulats recyclés sous forme de fines (Dmax < 80 µm) comme addition minérale en substitution du ciment pour les mortiers et bétons ou bien comme constituant principal de Liants Hydrauliques Routiers (LHR) pour le traitement des sols en place. Deux matériaux source sont utilisés, à savoir : un béton aux propriétés connues et maitrisées et un granulat issu d’une plateforme de recyclage représentatif d’une filière de production. De ces deux matériaux, des fines sont fabriquées par un protocole couplé de concassage et criblage avec ou sans traitement thermique à haute température puis caractérisées (caractérisation physico-chimique, minéralogique et réactivité hydraulique résiduelle) en vue d’établir une cartographie complète de leur potentiel de valorisation en fonction de leur origine. Le premier objectif intitulé « fabrication d’une addition minérale à base de fines » traite de l’effet de cette addition sur le comportement rhéologique, mécanique et sur les propriétés de durabilité de mortiers. Malgré un verrou normatif lié à l’utilisation de matières non référencées dans les normes des matériaux cimentaires, les résultats de ce travail démontrent la faisabilité d’introduire des fines en substitut d’additions classiques tel que le filler calcaire dans des proportions largement supérieures à celles imposées. Le second objectif intitulé « fabrication de liants hydrauliques routiers à base de fines » traite de la conception de LHR à base de fines pour le traitement des sols en place. C’est à partir d’un sol témoin reconstitué en laboratoire que deux familles de LHR à base de fines traitées et non traitées sont conçues, testées et comparées à des liants hydrauliques routiers commercialisés et enfin optimiséesThis thesis work focuses on the valorization of recycled aggregates as main component for hydraulic binders. This is included in a current issue of waste management, protection of natural resources and environment, reduction of greenhouse gases emissions in cement production. In France, on 260 millions tons of inert wastes produced per year, 90 millions tons are still stored in non-hazardous landfill. This waste deposit has to be reduced to increase the production of recycled aggregates currently estimated at 15 million tons per year. In view of this, this research is aimed to enhance the valorization of recycled aggregates into powder form (Dmax < 80 microns) as a mineral addition in substitution of cement for mortar and concrete or as main constituent of Hydraulic Road Binders (HRB). Two sources of materials are used : a five years old concrete and a recycled aggregates come from a recycling plant. Powders are prepared by crushing and sieving with or without high-temperature heat treatment and characterized (physical, chemical and mineralogical characterizations : residual hydraulic reactivity) to evaluate their potential valorization based on their origin.The first objective, entitled “Conception of mineral addition using powder of recycled aggregates”, deals with of the influence of this new materials on rheological, mechanical and durability properties of mortars. The results of this study allow us to evaluate the benefits of incorporating powder obtained by crushing/sieving of recycled aggregates as cement or limestone substitute used in the composition of a mortar. The second objective, entitled "conception of the Hydraulic Road Binders using powders of recycled aggregates", deals with the design of HRB by a comparative approach with HRB manufactured. The characteristics of binders are tested on mortars and on samples of treated soil and the results show that it's possible to produce an HRB rich in powders of recycled aggregates with or without cement which can efficiently stabilize clayey soils

Robot assisted therapy is becoming increasingly popular. Research has proven it can be of benefit to persons dealing with a variety of disorders, such as Autism Spectrum Disorder (ASD), Attention Deficit Hyperactivity Disorder (ADHD), and it can also provide a source of emotional support e.g. to persons living in seniors’ residences. The advancement in technology and a decrease in cost of products related to consumer electronics, computing and communication has enabled the development of more advanced social robots at a lower cost. This brings us closer to developing such tools at a price that makes them affordable to lower income individuals and families. Currently, in several cases, intensive treatment for patients with certain disorders (to the level of becoming effective) is practically not possible through the public health system due to resource limitations and a large existing backlog. Pursuing treatment through the private sector is expensive and unattainable for those with a lower income, placing them at a disadvantage. Design and effective integration of technology, such as using social robots in treatment, reduces the cost considerably, potentially making it financially accessible to lower income individuals and families in need. The Objective of the research reported in this manuscript is to design and implement a social robot that meets the low-cost criteria, while also containing the required functions to support children with ASD. The design considered contains knowledge acquired in the past through research involving the use of various types of technology for the treatment of mental and/or emotional disabilities.

This project explores opportunities in designing hybrid digital/physical smell rehabilitation video games using no unique game peripherals. During a 13-week process, three major iterations were created and externally tested on a small user group. The first two iterations contained five simple minigames that served to explore different types of game concepts. For the final iteration, two minigames were fully developed, a slow- and fast-paced game. The main findings were that slow-paced better-facilitated smell training than fast-paced games; aesthetics increased the player’s focus on small training; not utilising unique game peripherals limited the design opportunities and implementation of smell mechanics.

Full textAbstract:
À toutes les échelles de l'Astrophysique, l'impact de l'ionisation venant des étoiles massives est une question cruciale. A l'échelle galactique, l'ionisation peut réguler la formation des étoiles en soutenant les nuages moléculaires contre l'effondrement gravitationnel et à l'échelle stellaire, diverses indications pointent vers une naissance possible du système solaire à proximité des étoiles massives. À l'échelle du nuage moléculaire, il est clair que le gaz chaud et ionisé comprime le gaz froid qui l'entoure, conduisant à la formation des piliers, des globules, et des coquilles de gas dense dans lesquelles des coeurs pré-stellaires sont observés. Quels sont les mécanismes de formation de ces structures? La formation de ces coeurs pré-stellaires est-elle déclenchée par l'ionisation ou préexistante ? Les étoiles massives ont-elles un impact sur la distribution en densité du gaz environnant ? Ont-elles un impact sur la distribution des étoiles en fonction de leur masse (la fonction de masse initiale, IMF) ? Cette thèse vise à apporter des éléments de réponse à ces questions, en se concentrant en particulier sur la compréhension de la formation des structures entre le gaz froid et ionisé. Nous présentons l'état de l'art des travaux théoriques et des observations des régions ionisées (régions Hii) et nous introduisons les outils numériques qui ont été développés pour modéliser l'ionisation dans les simulations d'hydrodynamique turbulente effectuées avec le code HERACLES. Grâce aux simulations, nous présentons un nouveau modèle pour la formation des piliers basés sur la courbure et l'effondrement de la coquille dense sur elle-même et un nouveau modèle pour la formation de globules basé sur la turbulence du gaz froid. Plusieurs diagnostics ont été développés pour tester ces nouveaux modèles sur les observations. Si les piliers sont formés par l'effondrement de la coquille dense sur elle-même, le spectre en vitesse d'un pilier en formation présente un spectre avec une composante décalée vers le rouge et une composante décalée vers le bleu correspondant aux parties de la coquille en avant-plan et en arrière-plan qui rentrent en collision sur la ligne de visée. Si les globules émergent en raison de la turbulence du nuage moléculaire, le spectre en vitesse de ces globules est décalé à des vitesses différentes de celles de la coquille, des piliers et des coeurs denses qui suivent l'expansion globale de la région H ii. Un autre diagnostic est l'impact de la compression sur la fonction de densité de probabilité (PDF) du gaz froid. La distribution a un double pic lorsque la pression dynamique turbulente est faible par rapport à la pression du gaz ionisé. Il s'agit de la signature de la compression causée par l'expansion de la bulle ionisée. Quand la turbulence est élevée, les deux pics fusionnent et la compression peut encore être identifiée, mais la signature est moins claire. Nous avons utilisé des cartes de densité de colonne Herschel et des données de raies moléculaires pour caractériser la structure en densité et vitesse de l'interface entre le gaz ionisé et le gaz froid dans plusieurs régions : RCW 120, RCW 36, Cygnus X, la Nébuleuse de la Rosette et de l'Aigle. En plus des diagnostics issus des simulations, des prédictions analytiques des paramètres de la coquille et des piliers ont été testées et confrontées aux observations. Dans toutes ces régions, les modèles analytiques et les diagnostics issus des simulations donnent des résultats concluants. La structure en vitesse d'un pilier en formation dans la nébuleuse de la Rosette suggère qu'il a été formé par l'effondrement de la coquille sur elle-même et la dispersion des vitesses moyennes des globules dans Cygnus X et dans la Nébuleuse de la Rosette tend à confirmer leur origine turbulente. La compression due au gaz ionisé est visible sur la PDF du gaz froid dans la plupart des régions étudiées. Ce résultat est important pour le lien entre l'IMF et les propriétés globales du nuage. Si l'IMF peut être déduite de la PDF d'un nuage, l'impact des étoiles massives sur la PDF doit être pris en compte. En outre, nous présentons des simulations dédiées de RCW 36 qui suggèrent que les coeurs denses au bord du gaz ionisé ne sont pas pré-existants, leur formation a été déclenchée par la compression due à l'ionisation. En conséquence, l'ionisation des étoiles massives est un processus clé qui doit être pris en compte pour la compréhension de l'IMF. En annexe, nous présentons également des travaux réalisés en parallèle de cette thèse : l'échange de charge dans la collision entre vents planétaires et stellaires, en collaboration avec le professeur E. Chiang, à l'école d'été ISIMA 2011 à Pékin; et le test de site en sub-millimétrique sur la station Concordia en Antarctique avec l'équipe CAMISTIC (PI : G. Durand).

Full textAbstract:
Actuellement, les circuits numériques nécessitent d'être de plus en plus performants. Aussi, les produits doivent être conçus le plus rapidement possible afin de gagner les précieuses parts de marché. Les méthodes rapides de conception et l'utilisation de MPSoC ont permis de satisfaire à ces exigences, mais sans tenir compte précisément de l'impact du vieillissement des circuits sur la conception. Or les MPSoC utilisent les technologies de fabrication les plus récentes et sont de plus en plus soumis aux défaillances matérielles. De nos jours, les principaux mécanismes de défaillance observés dans les transistors des MPSoC sont le HCI et le NBTI. Des marges sont alors ajoutées pour que le circuit soit fonctionnel pendant son utilisation, en considérant le cas le plus défavorable pour chaque mécanisme. Ces marges deviennent de plus en plus importantes et diminuent les performances attendues. C'est pourquoi les futures méthodes de conception nécessitent de tenir compte des dégradations matérielles en fonction de l'utilisation du circuit. Dans cette thèse, nous proposons une méthode originale pour simuler le vieillissement des MPSoC à haut niveau d'abstraction. Cette méthode s'applique lors de la conception du système c.-à-d. entre l'étape de définition des spécifications et la mise en production. Un modèle empirique permet d'estimer les dégradations temporelles en fin de vie d'un circuit. Un exemple d'application est donné pour un processeur embarqué et les résultats pour un ensemble d'applications sont reportés. La solution proposée permet d'explorer différentes configurations d'une architecture MPSoC pour comparer le vieillissement. Aussi, l'application la plus sévère pour le vieillissement peut être identifiée.

La chaîne d'analyse est constituée : d'une simulation de ciel observé millimétrique, d'algorithmes originaux d'extraction d'amas SZ à partir des cartes observées, d'un modèle statistique des effets de sélection de la chaîne de détection, et enfin d'outils d'analyse des catalogues
des sources détectées pour contraindre les paramètres cosmologiques. Je m'intéresse au cas des expériences multi-fréquences dotées de caméra bolométrique. J'applique ces outils à une prospective pour l'expérience Olimpo.

Les Globules Cométaires sont des petits nuages denses que l'on observe fréquemment dans l'environnement d'étoiles 0 - B dans les régions HI!. Ces nuages sont remarquables par leur bord brillant et leur structure cométaire. Le sujet de cette thèse est une étude de la formation et de l'évolution de ces objets d'un point de vue numérique, analytique et observationnel. Nous montrons que le mécanisme de photo-ionisation par les étoiles proches (Implosion Radiative) peut rendre compte à lui-seul de la formation des globules cométaires. Numériquement, il ressort que la séquence d'évolution comprend deux principales étapes: une phase d'implosion brève suivie de la phase cométaire communément observée, beaucoup plus longue. Bien que difficile à observer, seule la première phase possède une signature spectroscopique indiscutable de la photo-ionisation. Sous certaines conditions d'ionisation des instabilités de type Rayleigh-Taylor à petite et grande échelle se développent dans le front d'ionisation et conduisent éventuellement à la destruction des nuages. Tous les globules en phase cométaire apparaissent être soutenus contre la pression du milieu extérieur par un champ magnétique statique qui semble suivre la loi de Heiles. Une étude analytique montre que tous ces nuages sont gravitationnellement stables. Les cartes de brillance synthétisées à partir des modèles numériques reproduisent avec vraisemblance les morphologies observées de nuages cométaires. Des observations radio-millimétriques du globule CG7S dans la région HII S190 ont permis de tester de manière non-ambigüe le modèle d'Implosion Radiative. Les caractéristiques observationelles de CG7S sont en bon accord avec les prédictions du modèle et ont pu être reproduites numériquement de manière satisfaisante. CG7S apparaît comme un des tous premiers nuages pré-cométaires observés à ce jour.

Full textAbstract:
The topic of this dissertation is the anatomical, psychological, and cultural examination of a human face in order to effectively construct an anatomy-driven 3D virtual face customization and action model. In order to gain a broad perspective of all aspects of a face, theories and methodology from the fields of art, engineering, anatomy, psychology, and cultural studies have been analyzed and implemented. The computer generated facial customization and action model were designed based on the collected data. Using this customization system, culturally-specific attractive face in Korean popular culture, “kot-mi-nam (flower-like beautiful guy),” was modeled and analyzed as a case study. The “kot-mi-nam” phenomenon is overviewed in textual, visual, and contextual aspects, which reveals the gender- and sexuality-fluidity of its masculinity. The analysis and the actual development of the model organically co-construct each other requiring an interwoven process. Chapter 1 introduces anatomical studies of a human face, psychological theories of face recognition and an attractive face, and state-of-the-art face construction projects in the various fields. Chapter 2 and 3 present the Bezier curve-based 3D facial customization (BCFC) and Multi-layered Facial Action Model (MFAF) based on the analysis of human anatomy, to achieve a cost-effective yet realistic quality of facial animation without using 3D scanned data. In the experiments, results for the facial customization for gender, race, fat, and age showed that BCFC achieved enhanced performance of 25.20% compared to existing program Facegen , and 44.12% compared to Facial Studio. The experimental results also proved the realistic quality and effectiveness of MFAM compared with blend shape technique by enhancing 2.87% and 0.03% of facial area for happiness and anger expressions per second, respectively. In Chapter 4, according to the analysis based on BCFC, the 3D face of an average kot-mi-nam is close to gender neutral (male: 50.38%, female: 49.62%), and Caucasian (66.42-66.40%). Culturally-specific images can be misinterpreted in different cultures, due to their different languages, histories, and contexts. This research demonstrates that facial images can be affected by the cultural tastes of the makers and can also be interpreted differently by viewers in different cultures.

Full textAbstract:
Afin d'améliorer les moyens d'observation en Haute Résolution Angulaire les télescopes acquièrent des diamètres de taille considérable. L'optimisation de ces grands télescopes de type E-ELT nécessite une caractérisation complète des sites devant les accueillir ainsi que des coupoles qui vont les abriter. En se basant sur une étude expérimentale effectuée sur le site du VLT (Paranal) on montre que la caractérisation verticale de la turbulence donnée par les profils de Cn2 et d'échelle externe est plus représentative des conditions réelles d'observation. Sachant, que le site qui va accueillir le futur E-ELT est à seulement quelques kilomètres de Paranal, les résultats vont servir à définir les spécifications des systèmes de compensation prévus pour cette nouvelle génération de grands télescopes. Cette étude a permis aussi la mise en évidence de la couche de surface et on a établi une estimation de son altitude et de son énergie. On montre que la couche de surface contribue significativement à la dégradation du front d'onde incident sur le télescope. Sa localisation près du sol soulève des questions sur son interaction avec les coupoles qui sont de même taille. LOTUCE un nouvel instrument développé dans le cadre de mon travail de thèse, a été proposé pour étudier l'interaction de cette couche de surface avec la coupole. En se basant sur la mesure des angles d'arrivée (AA) sur différents points du front d'onde, LOTUCE donne une estimation des paramètres optiques de la turbulence comme le paramètre de Fried, le temps de cohérence et l'échelle externe. La modélisation de la turbulence locale est alors possible en étudiant les courbes de covariance des AA dans les deux directions longitudinale et transverse. La dernière partie de ce travail a porté sur l'évolution temporelle de la turbulence optique. Il s'agit d'une étude basée sur l'estimation du temps de cohérence à partir de l'analyse statistique des fluctuations d'AA. Cette méthode utilisée par GSM a été validée par une simulation numérique. Ces résultats montrent que ce paramètre est plus sensible aux conditions de mesures et aux contraintes instrumentales.

Several studies indicates China is experiencing a water crisis, were several regions are suffering of severe water scarcity and rivers are heavily polluted. On the other hand, water is used inefficiently and wastefully: water use efficiency in the agriculture sector is only 40% and within industry, only 40% of the industrial wastewater is recycled. However, based on statistical data, China’s total water resources is ranked sixth in the world, based on its water resources and yet, Yellow River and Hai River dries up in its estuary every year. In some regions, the water situation is exacerbated by the fact that rivers’ water is heavily polluted with a large amount of untreated wastewater, discharged into the rivers and deteriorating the water quality. Several regions’ groundwater is overexploited due to human activities demand, which is not met by local. Some provinces have over withdrawn groundwater, which has caused ground subsidence and increased soil salinity. So what is the situation in China? Is there a water crisis, and if so, what are the causes?This report is a review of several global water scarcity assessment methods and summarizes the findings of the results of China’s water resources to get a better understanding about the water situation. All of the methods indicated that water scarcity is mainly concentrated to north China due to rapid growth, overexploitation from rivers and reduced precipitation. Whereas, South China is indicated as abundant in water resources, however, parts of the region are experiencing water scarcity due to massive dam constructions for water storage and power production. Too many dam constructions in a river disrupts flow of the river water and pollutants are then accumulated within floodgates.Many Chinese officials and scholars believe that with economic growth comes improved environmental quality when the economy has reached to a certain of per-capita level. However, with the present water situation it is not sustainable or possible for China to keep consuming and polluting its water resources. Improvement of environmental quality does not come automatically with increased income, and policies, laws and regulations are needed in order to stop further deterioration of the environment.China’s water situation is not any news and the key factor is human activities, but the question is how to solve it. China’s water crisis is much more complex than over exploitation of groundwater and surface water. There are three water issues in China: “too much water – floods, too little water – droughts, and too dirty water – water pollution” (Jun & Chen, 2001). Thus, solving China’s water crisis is a huge challenge to solve without negatively affecting the economic growth.

abstract: What if there is a way to integrate prosthetics seamlessly with the human body and robots could help improve the lives of children with disabilities? With physical human-robot interaction being seen in multiple aspects of life, including industry, medical, and social, how these robots are interacting with human becomes even more important. Therefore, how smoothly the robot can interact with a person will determine how safe and efficient this relationship will be. This thesis investigates adaptive control method that allows a robot to adapt to the human's actions based on the interaction force. Allowing the relationship to become more effortless and less strained when the robot has a different goal than the human, as seen in Game Theory, using multiple techniques that adapts the system. Few applications this could be used for include robots in physical therapy, manufacturing robots that can adapt to a changing environment, and robots teaching people something new like dancing or learning how to walk after surgery.
The experience gained is the understanding of how a cost function of a system works, including the tracking error, speed of the system, the robot’s effort, and the human’s effort. Also, this two-agent system, results into a two-agent adaptive impedance model with an input for each agent of the system. This leads to a nontraditional linear quadratic regulator (LQR), that must be separated and then added together. Thus, creating a traditional LQR. This new experience can be used in the future to help build better safety protocols on manufacturing robots. In the future the knowledge learned from this research could be used to develop technologies for a robot to allow to adapt to help counteract human error.Dissertation/Thesis

Decades of scaling in semiconductor technology has resulted in a drastic reduction in the cost and size of unit computing. This has enabled computing capabilities in small form factor wearable and implantable devices. These devices communicate with each other to form a network around the body, commonly known as the Wireless Body Area Network (WBAN). Radio wave transmission over air is the commonly used method of communication among these devices. However, the human body can be used as the communication medium by utilizing its electrical conductivity property. This has given rise to Human Body Communication (HBC), which provides higher energy efficiency and enhanced security compared to over the air radio wave communication enabling applications like remote health monitoring, secure authentication. In this thesis we characterize the human body channel characteristics at low frequencies, utilize the insight obtained from the channel characterization to build high energy-efficiency, interference-robust circuits and demonstrate the security and selectivity aspect of HBC through a Common Off the Shelf (COTS) component-based system. First, we characterize the response of the human body channel in the 10KHz1MHz frequency range with wearable transmitter/ receiver to study the feasibility of using it as a broadband communication channel. Voltage mode measurements with capacitive termination show almost at-band response in this frequency range, establishing the body as a broadband channel. The body channel response is also measured across different interaction scenario between two wearable devices and a wearable and a computer. A bio-physical model of the HBC channel is developed to explain the measurement results and the wide discrepancies found in previous studies.We analyze the safety aspect of different type of HBC by carrying out theoretical circuit and FEM based simulations. A study is carried out among multiple subjects to assess the effect of HBC on the vital parameters of a subject. A statistical analysis of the results shows no signicant change in the vital parameters before and during HBC transmission, validating the theoretical simulations showing >!000x safety margin compared to the established ICNIRP guidelines. Next, an HBC transceiver is built utilizing the wire-like, broadband human body channel to enable high energy efficiency. The transceiver also provides robustness to ambient interference picked up by the human body through integration followed by periodic sampling. The transceiver achieves 6.3pJ/bit energy effciency while operating at a maximum data rate of 30Mbps, while providing -30dB interference tolerant operation. Finally, a COTS based HBC prototype is developed, which utilizes low frequency operation to enable selective and physically secure communication strictly during touch for Human Computer Interaction (HCI) between two wearable devices for the rst time. A thorough study of the effect of different parameters such as environment, posture, subject variation, on the channel loss has also been characterized to build a robust HBC system working across different use cases. Applications such as secure authentication (e.g. opening a door, pairing a smart device) and information exchange (e.g. payment, image, medical data, personal profile transfer) through touch is demonstrated to show the impact of HBC in enabling new human-machine interaction modalities.

Background: Medical practices of male and female physicians are different, especially for gender-specific medical conditions. When it comes to women's diseases, female physicians are most likely to pay attention to relevant medical information. For example menopause issues, Women's Health Initiative (WHI) study indicated that hormone replacement therapy (HRT) overall health risks exceed benefits under long-term using. When male and female physicians face of gender-specific medical information, their practices of which will be changed. Therefore, the study is aim to understand before and after WHI releasing, how do they prescribe hormone replacement therapy (HRT). Objectives: To describe treated prevalence rate and treated incidence rate of menopausal women during 2000-2007. Second, to analyze the menopausal women incidence cases of first visiting types (including type of HRT). In the end, after the WHI study report, male and female physicians HRT prescription change of the difference. Methods: A retrospective study, using the National Health Insurance database to observe over the age of 40 menopausal women incidence cases, the prescription of hormone replacement therapy behavior change. Results: Over the age of 40 menopausal women, treated incidence rate was 3.62% in 2000, declined to 1.09% in 2007. Using the GEE model to adjust for clustering effects. After the WHI study report, the less declined to prescribe HRT (OR = 0.46, 95% CI: 0.43-0.50). Male physicians are more likely to prescribe HRT than female physicians (OR = 1.51, 95% CI: 1.26-1 .80). Clinics are less likely to prescribe HRT than other medical care institutions; private hospitals are more likely to prescribe HRT than public hospitals. The WHI study effect on male and female physicians of the same, it is non-significant (male physician: OR = 0.47, 95% CI: 0.32-0.69) (female physician: OR = 0.42, 95% CI: 0.35 -0.51). Conclusion: WHI study made the HRT prescriptions treated of menopausal symptoms dropped significantly. But the WHI study effect on male and female physicians is similar. Either male or female physicians, after the WHI study released, HRT prescription to change of similar magnitude.
