Neville, Casey M. "Improved Electronics for the Hall A Detectors at JLab: Summing Modules and VDC Amplifier/Discriminator Cards." FIU Digital Commons, 2012. http://digitalcommons.fiu.edu/etd/794.
Full textAbstract:
Testing of summing electronics and VDC A/D Cards was performed to assure proper functioning and operation within defined parameters. In both the summing modules and the VDC A/D cards, testing for minimum threshold voltage for each channel and crosstalk between neighboring channels was performed. Additionally, the modules were installed in Hall A with input signals from shower detectors arranged to establish a trigger by summing signals together with the use of tested modules. Testing involved utilizing a pulser to mimic PMT signals, a discriminator, an attenuator, a scaler, a level translator, an oscilloscope, a high voltage power supply, and a special apparatus used to power and send signal to the A/D cards. After testing, modules were obtained that meet necessary criteria for use in the APEX experiment, and the A/D cards obtained were determined to have adequate specifications for their utilization, with specific results included in the appendix.

Full textAbstract:
Adherence to prescribed medications is a central feature of good clinical HIV care and a key factor in determining the effectiveness of treatment. This is especially true for HIV-infected patients, on antiretroviral treatment, where adherence is strongly associated with survival. HIV-associated tuberculosis is a major and increasing health problem, especially in sub-Saharan Africa. Clinical trials have demonstrated a benefit of isoniazid preventive therapy in preventing TB among HIV-infected persons, and its use among these patients is recommended. Nearly perfect compliance seems to be indispensable to obtain the maximum benefit from highly active antiretroviral treatment and prophylactic medications. Accurately assessing non-adherence is a necessary first step towards improving adherence to active antiretroviral treatment and isoniazid preventive therapy. The introduction of diary cards is being considered as a measure of adherence and as a tool to improve adherence among HIV-infected individuals receiving antiretroviral treatment or isoniazid preventive therapy. This was a preliminary study to evaluate the effectiveness of diary cards as intervention tool for promoting adherence to antiretroviral and prophylactic TB therapy in people living with HIV/AIDS, to evaluate the diary card as a tool to measure adherence and to evaluate the feasibility and acceptability of diary cards.

Full textAbstract:
This diploma thesis deals with the design and implementation of a computer-controlled device for testing gas boiler control units, especially in the development phase. The reason for creating a test facility is the inadequacy of older test systems and the automation of existing testing. The test device in development consists of individual different cards. Each of the cards inserted into the motherboard performs its function in the system. Each of the cards has a special functionality which simulates the real conditions of the developed product. The basis of most cards is a microcontroller with a Cortex-M core, which communicates with the connected computer using the MODBUS protocol on the RS-485 communication interface. All cards on the bus are connected in parallel and behaves as a SLAVE, while the computer behaves as a MASTER and requests data or sends commands to the cards. The cards represent status switches (switching sensors), resistance and analog temperature sensors, PWM inputs and outputs (for simulation of feedback pumps or flow meters with pulse output). The cards also include a flame simulator, which reliably simulates the electrical properties of the flame and at the same time acts as a fan simulator. The input of the control unit is taken care of by the input card, which is intended for digital detection of the voltage presence in the range of 5 to 230 V DC and AC. Simultaneously, a card for connecting the power supply at zero voltage and disconnecting at zero current is created to supply the tested device with alternating voltage. A schematic diagram was designed or simulated for each card, then the function was verified and on this basis the whole card was created, including the microcontroller firmware. The most suitable solution and function of each card is carefully described and evaluated. All the requirements of the assignment within the work were met and the whole test equipment was manufactured and verified in four versions. In the future, the device is ready for the implementation of an automatic flame simulator and other improvements of individual module cards.

The combination of the existing mobile system and the IEEE standard for WLAN makes way for development of the 4th generation mobile systems. Access for laptop-users to WLAN is today a reality giving a taste of that new generation. Designing a product that introduces WLAN networking for handheld computers would be a major step in the development spoken of. Accommodating existing WLAN PC Card for laptops to handheld PDAs gives a short time to market. Therefore a product prototype for a compact flash module was designed and manufactured to make way for the 4th generation indoor networking facilities on the market.

Full textAbstract:
International Telemetering Conference Proceedings / October 18-21, 2004 / Town & Country Resort, San Diego, CaliforniaM/A-COM, Inc. has developed a miniature Tactical Telemetry Module (TTM) for medium power (500 mW and 1 W) telemetry applications. The TTM demonstrates system integration of a multi-channel PCM encoder, lower S-band transmitter, and power regulation onto a single printed wiring board (PWB). The module is smaller than a standard business card and utilizes both COTS and M/A-COM proprietary technologies. The PCM encoder is designed for eight (8) analog inputs, eight (8) discrete inputs, and one (1) synchronous RS-422 serial interface. Data rates of 300 kbps to 6 Mbps are supported. The module incorporates a frequency programmable, phase-locked FM S-band transmitter. The transmitter utilizes M/A-COM’s new dual port VCO and high efficiency 500 mW and 1 W power amplifier MMIC’s. Additionally, switching power regulation circuits were implemented within the module to provide maximum operating efficiency. This paper reviews the design and manufacturing of the Tactical Telemetry Module (TTM) and its major components, and presents system performance data.

Full textAbstract:
This study compared the efficacy of using online dementia training modules on both direct and non-direct care providers in long-term care settings and how this impacted their delivery of Person Centered Care (PCC), as well as their knowledge of caring for residents with a diagnosis of Alzheimer Disease (AD), dementia. Traditional educational opportunities for staff working specifically with demented residents inside Memory Care Units (MCU) were investigated, along with an alternative approach of training all staff (to include direct and non-direct care providers). The option of utilizing online dementia training modules for all staff was then evaluated by using an observational Person Centered Care tool, to see if education had made an impact on interactions between staff and the demented residents that they care for. This study utilized a single-group, repeated measures design to test a 10-week, standardized and computerized set of 10 interactive training modules in a 60-bed MCU . Fifty-one observations were made between MCU residents and staff and included in this study, employing a single-group pre-post-posttest design. The findings suggest that online dementia training modules may be beneficial for both knowledge and delivery of PCC to staff in MCUs who care for residents with a diagnosis of AD.

Full textAbstract:
L'évolution des réseaux informatiques, et notamment d'Internet, s'ancre dans l'émergence de paradigmes prépondérants tels que la mobilité et les réseaux sociaux. Cette évolution amène à considérer une réorganisation de la gestion des données circulant au cœur des réseaux. L'accès à des services offrant de la vidéo ou de la voix à la demande depuis des appareils aussi bien fixes que mobiles, tels que les Smartphones, ou encore la perméabilité des informations fournies à des réseaux sociaux conduisent à s'interroger sur la notion d'identité numérique et, de manière sous-jacente, à reconsidérer les concepts de sécurité et de confiance. La contribution réalisée dans ce travail de thèse consiste, dans une première partie, à analyser les différents modèles d'identité numérique existants ainsi que les architectures de fédération d'identité, mais également les protocoles déployés pour l'authentification et les problèmes de confiance engendrés par l'absence d'élément sécurisé tel qu'une carte à puce. Dans une deuxième partie, nous proposons, en réponse aux éléments dégagés dans la partie précédente, un modèle d'identité fortement attaché au protocole d'authentification TLS embarqué dans un composant sécurisé, permettant ainsi de fournir les avantages sécuritaires exigibles au cœur des réseaux actuels tout en s'insérant naturellement dans les différents terminaux, qu'ils soient fixes ou mobiles. Enfin, dans une dernière partie, nous expliciterons plusieurs applications concrètes, testées et validées, de ce modèle d'identité, afin d'en souligner la pertinence dans des cadres d'utilisation pratique extrêmement variés.

Full textAbstract:
Mestrado em FinançasO presente trabalho de investigação visa analisar a tipologia dos indivíduos que em Portugal possuem cartão de crédito (posse) e o utilizam, atendendo à forma como liquidam o saldo do cartão de crédito no final do período ou como o usam pagando parte do saldo existente (uso). Estuda ainda as causas dos comportamentos dos indivíduos e famílias em relação à posse e uso do cartão de crédito. Existe uma teoria designada por credit card puzzle que é essencial ao debate teórico em torno dos cartões de crédito. Por falta de informação para pesquisa exata se existe ou não um puzzle em Portugal, procuro verificar se existe uma associação entre ter cartão de crédito com saldo negativo e diversas características da família como por exemplo: o escalão de rendimento disponível, a idade, a necessidade de pedir empréstimos, o indicador de pobreza, entre outras. A conclusão a que se chega é que há fortes indícios da existência de um credit card puzzle em Portugal. A pesquisa empírica sobre os fatores que determinam a posse e uso do cartão de crédito é baseada no Module Ad-Hoc “On Over-Indebtedness And Financial Exclusion-2008” (EU-SILC) para Portugal e EU, guiada por 10 hipóteses explicativas baseadas na literatura consultada. Os resultados obtidos são de que existe uma relação positiva entre o rendimento do agregado e a posse e uso do cartão de crédito; o número de pessoas no agregado familiar influencia a posse e o uso do cartão de crédito; conforme aumenta o grau de educação, aumenta também a posse do cartão de crédito, no entanto, o uso com saldo negativo, diminui; o género influencia a posse e uso do cartão de crédito, uma vez que é o sexo masculino o maior detentor da posse mas é o feminino o maior detentor do uso com saldo negativo; a nível da situação de atividade, são os empregados a possuírem mais o cartão de crédito e os desempregados a usarem-no mais; no estado civil são os casados que mais possuem e os solteiros os que mais usam com saldo negativo; em relação à idade, quem tem entre 26 e 35 anos possui mais, mas quem tem entre 19 e 25 usa com saldo negativo mais. Duas hipóteses testadas que são em geral omissas na literatura sobre os cartões de crédito tiveram resultados relevantes. Quem pede ajuda a familiares e amigos e possui cartão de crédito 333333usa-o menos do que quem não pode contar com essa ajuda; os que vivem acima do limiar da pobreza possuem com maior frequência cartão e utilizam-no com saldo negativo menos do que quem vive abaixo do limiar da pobreza. A investigação contribui para identificar quem são os utilizadores dos cartões de crédito, de que forma o usam em função das suas necessidades de crédito, de que forma contribui o uso com saldo negativo para o endividamento. São ainda efetuadas comparações internacionais quer em relação ao perfil do detentor de cartão de crédito quer em relação à explicação dos comportamentos.
This research aims to analyze how the Portuguese hold credit cards (owner) and use them taking in account the way they liquidate the credit card balance at the end of the period, or how do they use the debit balance paying just part of the existing balance (use). This research also investigates causes to individuals’ and families’ behavior regarding the possession and use of the credit cards. An existent theory called “credit card puzzle” is essential to the theoretical debate around the credit cards subject. Due to lack of information for exact research whether or not there is a puzzle in Portugal, I try to check if there is association between having credit card balance and various family characteristics such as: the level of disposable income, household size and the need for loans, the poverty indicator, among others. I reached the conclusion that there is strong evidence of the existence of a Credit Card Puzzle in Portugal. The empirical research on the factors that determine the possession and use of the credit card is based on the Ad-Hoc Module "On Over-Indebtedness and Financial Exclusion-2008" (EU-SILC) for Portugal and EU countries and guided by 10 explanatory hypotheses based on the literature consulted. The results point to a positive relationship between household income and the ownership and use of the credit card; the household size influences the ownership and the use of the credit card; as the level of education increases, so increases the ownership of the credit card, however, the use with negative balance, decreases; the gender influences the possession and credit card use, since it is the male gender that holds most credit cards but is the female gender the biggest holder of the use negative balance; considering employment status, employees is the group which holds more credit card and the unemployed group is the group that use more unbalanced; on marital status, married men hold more credit cards and singles use more unbalanced; considering age, those who are between 26 and 35 years old hold more credit cards, but those who are between 19 and 25 years old hold more unbalance. Generally omitted in the literature on credit cards, the two hypotheses tested have relevant results. Those who eventually can trust on family financial help and or friends financial help and have credit cards use less than those who cannot rely on such aid; those who live above the poverty line hold more frequently credit cards and use it with negative balance less than people who live below the poverty line, however, still 16% of households living below the poverty line own credit cards. This research helps to identify who are the users of credit cards, how they use them on the basis of their credit needs, and how carrying a negative balance contributes to indebtedness. International comparisons in relation both to the profile of the credit card holder and to explain personal behavior, were also carried out.

Full textAbstract:
This thesis is concerned with the simulation model of an OPAT dummy rider on a Norton motorcycle in different configured impacts with a rigid barrier. The mathematical equations used in describing the mass-spring-damper-based impacts have been given. The software used in designing the mathematical model have also been outlined. The simulation model was then calibrated against full scale crash tests by means of film analysis and the processed digitised measurements. This led to the investigations into numerical processing of differentiation and integration. A parametric study was also conducted to examine injury to the dummy rider based on some varying parameters. The simulation model was further verified by different configurations and also an introduction of an airbag. Finally, the model was extended to a HYBRID3 dummy rider on the same motorcycle in different configured impacts with a motor car. It is hoped that after the validations and verifications have been performed to examine the robustness of the simulation model, it can assist in the analyses of motorcycle impacts with the less frequent need of conducting a full scale crash test, so that safety design of a motorcycle can be established.

The modern automobile is a complex electromechanical system controlled by control systems which consist of several interdependent electronic control units (ECUs). Analysis of the data generated by these modules is very important in order to observe the interesting patterns among data. At Volvo Cars Corporation today, diagnostic read-out data is retrieved from client machines installed at workshops in different countries around the world. The problem with this data is that it does not show a clear picture as what is causing what i.e. tracking the problem. Diagnostic engineers at Volvo Cars Corporation perform routine based statistical analysis of diagnostic read-out data manually, which is time consuming and tedious work. Moreover, this analysis is restricted to basic level mainly statistical analysis of diagnostic readout data. We present an approach based on statistical analysis and cluster analysis. Our approach focused on analysing the data from a pure statistical stand-point to isolate the problem in diagnostic read-out data, thereby helping to visualize and analyse the nature of the problem at hand. Different general statistical formulae were applied to get meaningful information from large amount of DRO data. Cluster analysis was carried out to get clusters consisting of similar trouble codes. Different methods and techniques were considered for the purpose of cluster analysis. Hierarchical and non-hierarchical clusters were extracted by applying appropriate algorithms. The results obtained from the thesis work show that the diagnostic read-out data consist of independent and interdependent fault codes. Groups were generated which consist of similar trouble codes. Furthermore, corresponding factors from freeze frame data which shows significant variation for these groups were also extracted. These faults, groups of faults and factors were later interpreted and validated by diagnostic engineers.

O objetivo deste estudo foi analisar o efeito do treinamento f?sico aer?bico (TFA) na modula??o auton?mica card?aca, avaliado pela variabilidade da frequ?ncia card?aca (VFC), em mulheres com s?ndrome dos ov?rios polic?sticos (SOP). Participaram do estudo 30 mulheres na faixa et?ria entre 18 e 34 anos, com diagn?stico de SOP de acordo com o Consenso de Rotterdam, e foram divididas em dois grupos: 1) grupo treinamento (GT; n=15) que conclu?ram programa de treinamento aer?bico durante 16 semanas, tr?s vezes por semana e 40 minutos por sess?o; e 2) grupo controle (GC; n=15) que n?o participaram do treinamento. A VFC foi analisada antes e ap?s o per?odo de estudo, sendo analisada pelos m?todos linear e n?o-linear. Para avaliar o efeito do treinamento sobre as vari?veis da an?lise da VFC foi ajustado um modelo de an?lise de covari?ncia multivariado (MANCOVA) tendo como covari?veis o IMC (?ndice de massa corporal), a Insulina e a Testosterona e como fator explicativo o grupo (tratamento, controle). As caracter?sticas cl?nicas quanto ao peso, circunfer?ncia de cintura, IMC, press?o arterial, frequ?ncia card?aca, VO2 m?x (consumo m?ximo de oxig?nio), insulina de jejum e testosterona, n?o apresentaram diferen?a estatisticamente significativa (p>0.05) entre os grupos pr?-interven??o. Tanto a FC (frequ?ncia card?aca) como a press?o arterial sist?lica de repouso, apresentaram diminui??o estatisticamente significativa no grupo treinado ap?s as 16 semanas (p=0.016; p=0.001 respectivamente). Observaram-se aumentos significativos no RMSSD ( raiz quadrada da somat?ria dos quadrados das diferen?as entre os intervalos R-R normais adjacentes) - (p < 0,0001) e no SDNN (desvio-padr?o da m?dia de todos os intervalos RR normais) - (p = 0,002). Na an?lise espectral no dom?nio da frequ?ncia foi encontrado aumento significativo no AF (alta frequ?ncia) em unidades absolutas (p < 0,0001), a vari?vel AFun (alta frequ?ncia em unidades normalizadas) tamb?m apresentou um aumento significativo (p < 0,001), enquanto que BFun (baixa frequ?ncia em unidades normalizadas) demonstrou diminui??o significativa (p < 0,001). Na an?lise das vari?veis pelo m?todo n?o-linear foram encontradas diferen?as significativas na ES (Entropia de Shannon), 0V% (porcentagem de padr?es sem varia??o) e 2VD% (porcentagem de padr?es com duas varia??es diferentes) (p<0,05), caracterizando uma melhora na modula??o auton?mica da frequ?ncia card?aca do grupo treinado. O TFA melhorou a VFC em repouso de mulheres com SOP, caracterizado pelo aumento na modula??o parassimp?tica e redu??o da modula??o simp?tica na frequ?ncia card?aca. Os resultados refor?am a import?ncia da abordagem interdisciplinar na avalia??o e tratamento de mulheres com SOP, com vistas ? redu??o de morbidade relacionada ao sistema cardiovascular

Il devient important d'assurer que tout système critique est fiable. Pour cela différentes techniques existent, telles que le test ou l'utilisation de méthodes formelles. S'assurer que le comportement d'un vérifieur de byte code Java Card n'entraînera pas de faille de sécurité est une tâche complexe. L'automatisation totale de cette vérification n'à popr le moment pas été realisee. Des jeux de tests coûteux ont été produits manuellement, mais ils doivent être refaits à chaque nouvelle spécification. Les travaux présentés dans ce mémoire proposent une nouvelle méthode pour la génération automatique de tests de vulnérabilité. Ceux-ci reposent sur l'utilisation et la transformation automatique de modèles formels. Pour valider cette méthode, un outil à été développé puis utilisé sur différentes implémentations du vérifieur de byte code Java Card. Le langage de modelisation que nous avons utilisé est Event-B. Nos modèles représentent le comportement normal du système que l'on souhaite tester. Chaque instruction est modélisée comme un événement. Leur garde représente l'ensemble des conditions que doit satisfaire une instruction pour être acceptable. À partir de ce modèle initial, une succession de dérivations automatiques génère un ensemble de modèles dérivés. Chacun de ces modèles dérivés représente une faute particulière. On extrait de ces nouveaux modèles les tests de vulnérabilité abstraits. Ceux-ci sont ensuite concrétisés puis envoyés à un système à tester. Ce processus est assuré par notre logiciel qui repose sur les API Rodin, ProB, CapMap et OPAL.

Previous issue date: 2009-07-22Background: The myotonic dystrophy (MD) is a multisystem neuromuscular disease that can affect the respiratory muscles and heart function, and cause impairment in quality of life. Objectives: Investigate the changes in respiratory muscle strength, health-related quality of life (HRQoL) and autonomic modulation heart rate (HR) in patients with MD. Methods: Twenty-three patients performed assessment of pulmonary function, sniff nasal inspiratory pressure (SNIP), the maximal inspiratory (MIP) and expiratory (MEP) pressure, and of HRQoL (SF-36 questionnaire). Of these patients, 17 underwent assessment of heart rate variability (HRV) at rest, in the supine and seated positions. Results: The values of respiratory muscle strength were 64, 70 and 80% of predicted for MEP, MIP, and SNIP, respectively. Significant differences were found in the SF-36 domains of physical functioning (58.7 ? 31,4 vs. 84.5 ? 23, p<0.01) and physical problems (43.4 ? 35.2 vs. 81.2 ? 34, p<0.001) when patients were compared with the reference values. Single linear regression analysis demonstrated that MIP explains 29% of the variance in physical functioning, 18% of physical problems and 20% of vitality. The HRV showed that from supine position to seated, HF decreased (0.43 x 0.30), and LF (0.57 x 0.70) and the LF/HF ratio (1.28 x 2.22) increased (p< 0.05). Compared to healthy persons, LF was lower in both male patients (2.68 x 2.99) and women (2.31 x 2.79) (p< 0.05). LF / HF ratio and LF were higher in men (5.52 x 1.5 and 0.8 x 0.6, p <0.05) and AF in women (0.43 x 0.21) (p< 0.05). There was positive correlation between the time of diagnosis and LF / HF ratio (r = 0.7, p <0.01). Conclusions: The expiratory muscle strength was reduced. The HRQoL was more impaired on the physical aspects and partly influenced by changes in inspiratory muscle strength. The HRV showed that may be sympathetic dysfunction in autonomic modulation of HR, although with normal adjustment of autonomic modulation during the change of posture. The parasympathetic modulation is higher in female patients and sympathetic tends to increase in patients with longer diagnosis
Introdu??o: A distrofia miot?nica (DM) ? uma doen?a neuromuscular multissist?mica que pode afetar a musculatura respirat?ria e a fun??o card?aca, e ocasionar preju?zos na qualidade de vida. Objetivos: Investigar as altera??es na for?a muscular respirat?ria, qualidade de vida relacionada ? sa?de (QVRS), e modula??o auton?mica da freq??ncia card?aca (FC) em pacientes com DM. M?todos: Foram avaliados 23 pacientes quanto ? fun??o pulmonar, press?o inspirat?ria nasal sniff (SNIP), press?es respirat?rias m?ximas (PIm?x e PEm?x), e QVRS (question?rio SF-36). Destes, 17 realizaram avalia??o da variabilidade da frequ?ncia card?aca (VFC) em repouso, nas posturas supina e sentada. Resultados: Os valores da for?a muscular respirat?ria foram de 64, 70 e 80%predito para PEm?x, PIm?x, e SNIP, respectivamente. Foi encontrada diminui??o significativa nos dom?nios do SF-36 capacidade funcional (58.7 ? 31,4 vs. 84.5 ? 23, p<0.01) e disfun??o f?sica (43.4 ? 35.2 vs. 81.2 ? 34, p<0.001) comparado a valores de refer?ncia. A an?lise de regress?o linear mostrou que a PIm?x explica 29% da vari?ncia na capacidade funcional, 18% na disfun??o f?sica e 20% na vitalidade. A VFC mostrou que, da postura supina para a sentada, o espectro AF diminuiu (0.43 x 0.30) e o espectro BF (0.57 x 0.70) e a raz?o BF/AF (1.28 x 2.22) aumentaram, com p<0.05. Comparado a valores de refer?ncia, BF foi inferior (p<0.05) tanto nos pacientes homens (2.68 x 2.99), como nas mulheres (2.31 x 2.79). A raz?o BF/AF e o espectro BF foram maiores nos homens (5.52 x 1.5 e 0.8 x 0.6), e o espectro AF, nas mulheres (0.43 x 0.21), com p<0.05. Houve correla??o significativa positiva entre tempo de diagn?stico e raz?o BF/AF (r= 0.7, p< 0.01). Conclus?es: Indiv?duos com DM t?m for?a muscular expirat?ria diminu?da. A QVRS mostrou-se mais prejudicada em rela??o a aspectos f?sicos e parcialmente influenciada por varia??es na for?a muscular inspirat?ria. Pode haver disfun??o simp?tica na modula??o auton?mica da FC, com ajuste normal da postura supina para a sentada. A modula??o parassimp?tica ? superior em pacientes mulheres e a modula??o simp?tica tende a aumentar nos pacientes com maior tempo de diagn?stico

This Diploma thesis concern with generalized linear models and their application in bank practice. Especially to analyze retail loan repayment. First of all we see into theoretical viewpoint of generalized linear models. We shortly try to summarize problems of clasical linear model restrictions and after that we apply to theory on which generalized models are based. We introduce an overview of generalized linear models and after that we concern models, where dependent variable have multinomial and gamma distribution in detail. Main part this thesis is dedicated to data analysis about bank retail loans repayments. In this analysis we use those early mentioned models. We try to create good statistical models on which base the risk ratio of current bank clients could be predicted. The risk ratio is measured by two main indicators, which are: "overdue time" and "overdue amount". For analysis is used statistical software SAS.

La vérification de la résistance aux attaques des implémentations embarquées des vérifieurs de code intermédiaire Java Card est une tâche complexe. Les méthodes actuelles n'étant pas suffisamment efficaces, seule la génération de tests manuelle est possible. Pour automatiser ce processus, nous proposons une méthode appelée VTG (Vulnerability Test Generation, génération de tests de vulnérabilité). En se basant sur une représentation formelle des comportements fonctionnels du système sous test, un ensemble de tests d'intrusions est généré. Cette méthode s'inspire des techniques de mutation et de test à base de modèle. Dans un premier temps, le modèle est muté selon des règles que nous avons définies afin de représenter les potentielles attaques. Les tests sont ensuite extraits à partir des modèles mutants. Deux modèles Event-B ont été proposés. Le premier représente les contraintes structurelles des fichiers d'application Java Card. Le VTG permet en quelques secondes de générer des centaines de tests abstraits. Le second modèle est composé de 66 événements permettant de représenter 61 instructions Java Card. La mutation est effectuée en quelques secondes. L'extraction des tests permet de générer 223 tests en 45 min. Chaque test permet de vérifier une précondition ou une combinaison de préconditions d'une instruction. Cette méthode nous a permis de tester différents mécanismes d'implémentations de vérifieur de code intermédiaire Java Card. Bien que développée pour notre cas d'étude, la méthode proposée est générique et a été appliquée à d'autres cas d'études.

Full textAbstract:
Le comportement d'un véhicule autonome peut être affecté par divers facteurs internes tels que défaillance du système de bord, capteur, etc., ou par des facteurs externes tels que manœuvres risquées de la part de voisins immédiats menaçant une collision, des changements brusques de l'état des routes, etc. Cela peut entraîner une défaillance de la manœuvre de coordination, telle que le croisement de plusieurs véhicules à une intersection. Dans de telles situations, lorsque les conditions changent de manière dynamique et que la condition de fonctionnement nominale est violée par des influences internes ou externes, un véhicule autonome doit avoir la capacité d'atteindre la condition de risque minimal. Arrêter le véhicule est l’un des moyens d’atteindre un niveau de risque minimal. La thèse introduit un algorithme d'arrêt sécurisé qui génère des commandes pour véhicules autonomes en tenant compte de la présence de véhicules traditionnels. Un algorithme basé sur un modèle de contrôle prédictif est proposé, qui résiste aux erreurs provenant de la communication, la localisation, la mise en œuvre du contrôle et à la disparité des modèles. Les collisions évitées et la gêne ressentie par le conducteur sont deux paramètres d'évaluation. Les simulations montrent que le contrôleur robuste sous l'influence d'erreurs peut fonctionner aussi bien que le contrôleur non-robuste en l'absence d'erreursThe behaviour of an autonomous vehicle can be impacted by various internal factors like onboard system failure, sensor failure, etc. or by external factors like risky maneuvers by immediate neighbors threatening a collision, sudden change in road conditions, etc. This can result in a failure of coordination maneuver like multi-vehicle intersection clearance. In such situations when conditions dynamically change and the nominal operational condition is violated by internal or external influences, an autonomous vehicle must have the capability to reach the minimal risk condition. Bringing the vehicle to a halt is one of the ways to achieve minimal risk condition. This thesis introduces a safe stop algorithm which generates controls for multiple autonomous vehicles considering the presence of legacy manually driven vehicles on the road. A Model Predictive Control based algorithm is proposed which is robust to errors in communication, localization, control implementation, and model mismatch. Collisions avoided and discomfort faced by the driver are two evaluation parameters. Simulations show that the robust controller under the influence of errors can perform as well as the non-robust controller in the absence of these errors

Objetivo: Avaliar a modula??o auton?mica da freq??ncia card?aca(FC), a partir da an?lise de sua variabilidade(VFC), e verificar a sua correla??o com outros fatores de risco para as doen?as cardiovasculares em mulheres portadoras da S?ndrome dos Ov?rios Polic?sticos (SOP) e num grupo controle de mulheres ovulat?rias saud?veis. M?todos: Foram avaliadas 23 mulheres com diagn?stico de SOP pelo Consenso de Rotterdam e 23 mulheres ovulat?rias saud?veis, com idade variando entre 20 e 34 anos. Foram considerados os ?ndices da VFC no dom?nio do tempo (SDNN e rMSSD) e no dom?nio da frequ?ncia (baixa frequ?ncia-BF e alta frequ?ncia-AF), al?m de par?metros antropom?tricos, bioqu?micos e hormonais de avalia??o do risco cardiovascular. Para compara??es entre os grupos foram utilizados os testes estat?sticos de Mann-Whitney e teste t n?o-pareado, al?m do teste de correla??o de Pearson para an?lise de correla??es entre as vari?veis, com n?vel de signific?ncia de 5%. Resultados: Em compara??o ao grupo controle, as mulheres com SOP apresentaram n?veis significativamente mais baixos de progesterona e mais elevados de glicose, insulina, colesterol total, triglicer?deos, aspartato aminotransferase e prote?na C-reativa (PCR) de alta sensibilidade. Em rela??o ? VFC, as an?lises entre os grupos mostraram diferen?as estatisticamente significativas, com diminui??o dos ?ndices SDNN e rMSSD no grupo SOP, quando comparado ao grupo controle (p<0,05). A an?lise da VFC no dom?nio da freq??ncia tamb?m demonstrou valores estatisticamente inferiores para BF e AF no grupo SOP, em compara??o ao controle. Foram observadas correla??es negativas estatisticamente significativas entre o ?ndice de massa corporal e os ?ndices SDNN, BF e AF, indicando que a modula??o auton?mica diminui com o aumento do peso. xiv Tamb?m foram observadas correla??es negativas estatisticamente significativas entre os ?ndices de VT5FC e os n?veis de insulina de jejum, colesterol total, triglicer?deos e PCR de alta sensibilidade. Conclus?o: O estudo mostra que a modula??o auton?mica da FC em mulheres com SOP est?o reduzidas em compara??o a mulheres ovulat?rias saud?veis. Esse achado est? correlacionado com o ganho de peso, dislipidemia e par?metros de inflama??o e resist?ncia insul?nica. Nesse sentido, medidas preventivas devem ser enfatizadas na abordagem cl?nica das pacientes com SOP, especialmente aquelas envolvendo orienta??o nutricional e atividade f?sica regular

En el análisis cualitativo desarrollado a través de un focus group se encontraron diferentes afirmaciones y negaciones que son respaldadas a través del análisis cuantitativo con el modelo estadístico logístico binario; en este caso se demostró que todas las variables son importantes para un posible comprador de un auto híbrido; pero unas tienen mayor importancia que otras y esto determinaría que se deben llevar a cabo estrategias que estén relacionadas al precio y diseño del auto; ya que son las variables que obtuvieron mayor importancia en el análisis.This investigation has as purpose identify which are the factors more important for a possible buyer of a hybrid car in comparison of a conventional car in Lima Metropolitana, that is why qualitative and quantitative tools have been used to get a result; this will allow car brands to know which factor is more important for the consumer and to empower it through direct and indirect marketing strategies. In the qualitative analysis developed through a focus group, different affirmations and negations were found that are supported through quantitative analysis with the statistical binary logistic model; in this case it was shown that all the variables are important for a possible buyer of a hybrid car; but some are more important than others and this would determine that price and design should be the ones that have to have the focus of the strategies because they are the variables that obtained more importance in the statistical analysis.

The study’s purpose is to develop a generic model for make-or-buy decisions at Cardo.
To develop the model, a theoretical study was conducted, where four main aspects were identified: core capability, risk, cost and relationship. For each aspect, a tool to define what the aspects consist of was identified. The aspects were combined together into a model, called model version 1. To enhance and adjust the model to suit Cardo’s situation, an empirical study was conducted. In the empirical study, it was investigated how different sites within Cardo are currently working with make-or-buy decisions. Moreover, in the empirical study it was also revealed how Cardo is dealing with each of the aspects identified in theory. The combination of theory and empirical study formed the enhanced model, called model version 2. The last step in the procedure was to let several end-users review the model and suggest improvements. After this step, the final model was formed, called model version 3.The model combines the best practices from Cardo with the latest theoretical aspects. Using this model will help Cardo deal with make-or-buy decisions in a structured way. The model highlights the importance of connecting business strategy with the core capabilities of Cardo and provides a tool to identify this connection. Furthermore, the model highlights risks connected to outsourcing and provides tools to identify these risks. The model also applies a total cost approach. To calculate the different costs, a model is presented that functions as a guide when quantifying costs. Lastly, the model shows the importance of developing a proper relationship with the supplier according to the strategic importance of the product.Cardo AB is an international corporate group that has performed major organizational changes the last few years.

Introdu??o: Estimula??o transcraniana por corrente continua (ETCC) tem sido usada em estudos voltados para o tratamento da dor perif?rica cr?nica em pessoas com les?o medular (LM), mas seus efeitos sobre o sistema nervoso auton?mico (SNA) nestes indiv?duos s?o inexistentes e, portanto a necessidade de estudos ? de fundamental import?ncia, pois estes indiv?duos apresentam desbalan?o auton?mico, e sua intensidade ? dependente do grau e n?vel da les?o. Objetivo: Investigar se a ETCC sobre o c?rtex motor prim?rio ir? modular o controle do SNA em pessoas com LM e se estas altera??es s?o dependentes do grau e n?vel de les?o. M?todos: Estudo randomizado, placebo controlado, aplicou ETCC an?dica ou sham sobre o c?rtex motor prim?rio (M1), bilateralmente, com o eletrodo de refer?ncia sendo colocado na protuber?ncia occipital. Dezenove sujeitos (les?o incompleta baixa (n=7), completa baixa (n=9) e completa alta (n=3)) visitaram o laborat?rio tr?s vezes e receberam ETCC ativa ou sham por 13min. A variabilidade da frequ?ncia card?aca (VFC) foi medida antes, durante e p?s-estimula??o. A VFC foi calculada usando a analise espectral batimento a batimento dos intervalos derivados das ondas r-r. Resultados: A ETCC modulou o sistema nervoso auton?mico de forma divergente nos grupos analisados. Nos indiv?duos com LM completa alta a ETCC n?o alterou a VFC. Para os indiv?duos com LM incompleta baixa a ETCC alterou a VFC no sentido de aumentar o simp?tico e reduzir o parassimp?tico e para os indiv?duos com LM completa baixa a ETCC reduziu o simp?tico e aumentou o parassimp?tico. Conclus?o: O presente estudo observou que a ETCC an?dica aplicada sobre o c?rtex motor prim?rio de forma bilateral, conseguiu modular o balan?o do SNA em pessoas com les?o medular e este efeito ? dependente do grau e n?vel de les?o. Palavras-chave: Estimula??o Transcraniana; Sistema nervoso auton?mico; Variabilidade da frequ?ncia card?aca; Les?o medular.
Introduction: Transcranial Direct Current Stimulation (tDCS) has been used in studies for the treatment of chronic pain, but their effects on the autonomic nervous system (ANS) are non-existent. Therefore, the need for studies is of fundamental importance, as these individuals have autonomic imbalance and the intensity of this is dependent on the degree and level of injury. Objective: We investigated the effect of tDCS on the ANS in people with spinal cord injury (SCI) with different degrees and levels of injury. Methods: Randomized, placebo-controlled, double-blind, applied anodal tDCS or sham on the primary motor cortex (M1), bilaterally. The subjects (lower incomplete injury, n = 7; lower complete injury, n = 9; and high complete thoracic injury, n = 3) visited the laboratory three times and received active or sham tDCS for 13min. The heart rate variability (HRV) was measured before, during and after stimulation and analyzed the variables LF, HF and LF / HF. Results: The tDCS modulated the ANS in different ways among the groups. In individuals with SCI high complete thoracic the tDCS did not change the HRV. However, for individuals with SCI low incomplete, tDCS changed the HRV in order to increase sympathetic (LF, p = 0.046) and reduced parasympathetic (HF, p = 0.046). For individuals SCI low complete to tDCS changed the HRV reduction sympathetic (LF, p = 0.017) and increased parasympathetic (HF, p = 0.017). Conclusions: The present study suggests that anodal tDCS applied on the motor cortex bilaterally could modulate the ANS balance in people with spinal cord injury and that this effect is dependent on the degree and level of injury.

Os testes de caminhada de 6 minutos (TC6MIN) e 400 metros (TC400M) s?o utilizados como uma alternativa pr?tica e de baixo custo para avaliar a aptid?o aer?bia e o desempenho obtido nesses testes est? relacionado com n?veis de sa?de, capacidade funcional e risco de mortalidade. Al?m do desempenho nos testes, a avalia??o cardiovascular por meio da frequ?ncia card?aca (FC) de recupera??o (FCR) e da variabilidade da frequ?ncia card?aca (VFC) p?s-exerc?cio t?m sido utilizados como informa??o de n?veis de sa?de e risco de mortalidade. O Tai Chi Chuan (TCC) pode aumentar a capacidade aer?bia, al?m de modificar o controle auton?mico. Objetivos: O objetivo foi analisar o desempenho e marcadores auton?micos entre idosas praticantes de TCC e sedent?rias em testes de caminhada indiretos. M?todos: Foram avaliadas 36 idosas, sendo 18 praticantes de TCC, com tempo de pr?tica de pelo menos 6 meses e n?o mais de 1 ano e que realizassem apenas o TCC, e 18 idosas sedent?rias. Para o TC6MIN, os sujeitos seguiram as recomenda??es do protocolo sugerido pela American Thoracic Society (ATS, 2002), e para o TC400M foi utilizado o protocolo do estudo de Simonsick et al.2001. A FCR foi considerada como a diferen?a absoluta entre a FC obtida ao final dos testes, e as FCs medidas no primeiro (FCR60 ) e segundo minuto (FCR120 ). O protocolo de coleta da VFC utilizado foi o recomendado pela Task Force (1996). Ap?s a constata??o da normalidade de distribui??o dos dados mediante teste de Shapiro Wilk, empregou-se o teste t de Student para amostra independentes ou Mann- Whitney caso n?o apresentasse normalidade, coeficiente de correla??o intraclasse (CCI; com 95% de intervalo de confian?a) e Bland- Altman (com 95% dos limites de concord?ncia). Resultados: O desempenho em ambos os grupos apresentou uma boa confiabilidade. As idosas do TCC obtiveram um melhor desempenho nos testes em compara??o com as sedent?rias. Al?m do mais, a FCR apresentou boa confiabilidade na em ambos os grupos, e a FCR das idosas do TCC apresentaram uma melhor reativa??o parassimp?tica quando comparadas com as idosas sedent?rias. Considerando a reprodutibilidade da VFC na an?lise linear e simb?lica, tanto nas idosas praticantes de TCC como nas idosas sedent?rias apresentaram boa confiabilidade. O comportamento da VFC n?o foi significante entre os grupos. Conclus?es: Foi encontrada uma boa confiabilidade no desempenho dos grupos avaliados, e nas vari?veis auton?micas podendo estar associados a intensidade subm?xima atingida em todos os testes. Al?m do mais, o desempenho obtido nos testes podem ser usados na obten??o de medidas confi?veis na avalia??o cardiorrespirat?ria, bem como a utiliza??o da FCR e da VFC parece garantir a confiabilidade dos dados utilizados para para medida do controle auton?mico card?aco. O TCC parece que favorece a um melhor desempenho em testes indiretos, al?m de uma melhor reativa??o parassimpatica considerando a FCR, mas, considerando a VFC n?o foi encontrada diferen?a significante entre as idosas

This dissertation is inserted in the Research Line: Text and speech in the oral and written modalities of the Program of Postgraduate Studies in Portuguese Language. It is the study of a model whose purpose is to guide the writing process of the didactic unit document, by teachers authors or experts in the disciplines. We use the nomenclature didactic unit as a series of teaching and learning activities assembled and organized for learning purposes (LIBÂNEO; FREITAS, [2009]). This model, named didactic unit template, is built with the components of a didactic unit, and may contain autoforming features, which facilitate the production of the final document, even by less experienced authors. Our main objective was to better understand the template, its composition and socio-rhetorical organization, to reflect if and in what way it affects the quality of the material it supports, contributing to the teaching and learning process. We use as theoretical foundation the socio-rhetorical studies of gender. The authors consulted were Swales (1990; 2004); Miller (1984, 2014); Bhatia (1993, 2001, 2012); Bazerman (2000); Bazerman and Miller (2011); Aguiar (2011); Biasi-Rodrigues and Bezerra (2012); Campos (2014); Crescitelli and Campos (2015) and Motta-Roth (1998; 2004). Being restricted the access to templates, for reasons of copyright, we began our study by textbooks, in view of being a type of text whose components are included in didactic units and for having their use recognized in the support of educational activities. We analysed ten books and, of these, we selected two to present the more detailed analysis. Having obtained a template of allowed use, named as Template COL, we were able to analyse it and reproduce it here. This model was created by the Commonwealth of Learning (COL), an international organization supporting education, especially in less developed countries. For a second example, we describe the items of a didactic unit template, based on our experience working with this type of model. In these models, we identify rhetorical moves and steps, according to Swales' (1990) CARS Model, to better understand the organization and interrelationship of its elements. In the course of research, we have a contact with a case study of a researcher active in the development of education in Namibia (FRÖHLICH, 2008), which shows the practical use of the template to support authors, even with less experience. The contact with the Template COL and the reality in which it is used has shown us that – in addition to helping in the quality of the final document, as we have seen previously because of our professional experience – the application of templates can be a valuable resource, including in less favored regions. Analysis by socio-rhetorical principles allowed us to see the text through more than one approach, considering its objectives, its functioning and the people affected by it. For us, it has been evident that the careful planning of the didactic unit and the construction of its final document in an organized way are important so that it fulfills its purpose with students and teachers. In this composition, the author can be aided by the template, which also requires planning and constitutes a tool to support the preparation of documents for educational purposes
Esta dissertação insere-se na Linha de Pesquisa: Texto e discurso nas modalidades oral e escrita do Programa de Estudos Pós-Graduados em Língua Portuguesa. Trata-se do estudo de um modelo cuja finalidade é guiar o processo de escrita do documento unidade didática, por autores professores ou especialistas nas disciplinas. Empregamos a nomenclatura unidade didática como sendo uma série de atividades de ensino e aprendizagem reunidas e organizadas com propósitos de aprendizagem (LIBÂNEO; FREITAS, [2009]). Esse modelo, nomeado template de unidade didática, é construído com os componentes de uma unidade didática, podendo conter recursos de autoformatação, que facilitam a produção do documento final, mesmo por autores menos experientes. Nosso objetivo principal foi conhecer melhor o template, sua composição e organização sociorretórica, para refletir se e de que maneira ele afeta a qualidade do material a que dá suporte, contribuindo com o processo de ensino e aprendizagem. Utilizamos como fundamentação teórica os estudos sociorretóricos de gênero. Os autores consultados foram Swales (1990; 2004); Miller (1984; 2015); Bhatia (1993; 2001; 2012); Bazerman (2000); Bazerman e Miller (2011); Aguiar (2011); Biasi-Rodrigues e Bezerra (2012); Crescitelli e Campos (2015) e Motta-Roth (1998; 2004). Sendo restrito o acesso a templates, por questões autorais, iniciamos nosso estudo por livros didáticos, tendo em vista serem um tipo de texto cujos componentes figuram em unidades didáticas e por terem seu uso consagrado no apoio a atividades educacionais. Analisamos dez livros e, desses, selecionamos dois para apresentar a análise mais detalhada. Tendo obtido um template de uso permitido, nomeado como Template COL, pudemos analisá-lo e reproduzi-lo aqui. Esse modelo foi criado pela Commonwealth of Learning (COL), organização internacional de apoio à educação, principalmente em países menos desenvolvidos. Para uma segunda exemplificação, descrevemos os itens de um template de unidade didática, baseadas em nossa experiência de trabalho com esse tipo de modelo. Identificamos, nesses modelos, os movimentos retóricos e passos, conforme o Modelo CARS, de Swales (1990), para entender melhor a organização e a inter-relação de seus elementos. No percurso de pesquisa, conhecemos um estudo de caso de uma pesquisadora atuante no desenvolvimento da educação na Namíbia (Fröhlich, 2008), que evidencia a utilidade prática do template para apoiar autores, mesmo com menor experiência. O contato com o Template COL e com a realidade em que é utilizado mostrou-nos que – além de auxiliar na qualidade do documento final, como já havíamos constatado anteriormente em razão de nossa experiência profissional – a aplicação de templates pode ser um valioso recurso, inclusive em regiões menos favorecidas. A análise por princípios sociorretóricos permitiu-nos ver o texto por mais de um enfoque, considerando seus objetivos, seu funcionamento e as pessoas que por ele são afetadas. Evidenciou-se, para nós, ser relevante o planejamento criterioso da unidade didática e a construção de seu documento final de maneira organizada, para que cumpra seu propósito junto a estudantes e professores. Nessa composição, o autor pode ser auxiliado pelo template, que requer, igualmente, planejamento e constitui uma ferramenta de apoio à elaboração de documentos com fins didáticos

La société Autobiz édite et diffuse de l’information sur le secteur automobile. Cette thèse contribue à l’enrichissement de cette information et à une meilleure compréhension du marché de l’occasion par l’élaboration des modèles de prédiction du prix des véhicules et du délai de vente qui leur est associé. Nous avons eu à notre disposition une base de données réelles constituée d’annonces de sources diverses induisant un nombre considérable d’outliers. Ainsi, la première partie de travail s’est consacrée à la construction de méthodes de détection d’outliers incluant aussi bien de simples règles empiriques qu’un test statistique dont les propriétés asymptotiques ont été étudiées. Partant d’un état de l’art sur la prédiction des prix des véhicules d’occasion, il est apparu que les études existantes soulèvent le besoin de fonder une méthodologie d’analyse plus rigoureuse. Cette méthodologie a été développée dans un objectif de proposer des solutions automatisables et adaptées aux contraintes imposées par les experts. Nous faisons alors l’hypothèse que les prix des véhicules d’une même version se déprécient en fonction de l’âge et du kilométrage selon une forme qui lui est propre. La dernière partie du travail est dédiée à l’analyse des délais de vente. Dans un premier temps, nous caractérisons la variable associée aux délais de vente. Ensuite nous proposons une modélisation de cette variable par une régression à l’échelle d’un segment correspondant à l’arborescence marque-modèle-carrosserie-énergie en fonction des variables liées au kilométrage, au prix et à l’âge. Enfin, nous discutons de la possibilité de modéliser le nombre de véhicules vendus dans une période donnée selon une loi binomiale négativeAutobiz publishes information on the automotive sector. The subject of this the-sis is to give more tools for best understanding the used cars market by proposing modeling the price and the sale duration of vehicles. In our disposal we have a dataset consisted of used car advertisements automatically collected from the most popular website in France. Such data records often include outlying values. So, we need to start our analysis by considering outliers problem and we propose an outliers detector for univariate case for which we study asymptotic properties. Next, we develop a predicting model for used cars price. Although enumerable amount of works are stored in the literature we see that each of them lacks rigorous statistical foundations. We investigate the relationships between the price, the mileage, the age and others vehicle characteristics. More precisely we discuss how incorporate these variables in a model and compare different modeling approaches with the object to find the one best fitting the dataset and easy to implement. Expert’s opinions are minded at different stages of the model-building process. Next, we identify variables and how they affect the probability of a used vehicle’s sale from a list of explanatory variables related to price, mileage and age. In the sequel, we build a model allowing predicting the sale duration. Finally, we discuss about modeling sales of used cars by using the negative binomial distribution

O objetivo desta dissertação é analisar a viabilidade do transporte marítimo de automóveis novos por cabotagem no Brasil, buscando uma alternativa de transporte, pois atualmente este transporte somente é realizado pelo modal rodoviário. A utilização da cabotagem como transporte de cargas tem aumentado desde a promulgação da Lei de Modernização dos Portos (lei 8.630), em 1993. Nesta mesma época, as fábricas de veículos começaram a passar por um processo de desconcentração geográfica, se deslocando da região Sudeste, e necessitando de transportes mais eficientes. Para observar se tal alternativa é viável economicamente, foi elaborado um estudo de caso e foram usados os dados de uma montadora específica. Esta montadora possui fábricas nos municípios de Camaçari (BA) e de São Bernardo do Campo (SP) e precisa distribuir sua produção em 275 concessionárias espalhadas pelo país. A partir do levantamento e análise dos custos rodoviários e de cabotagem para o transporte de automóveis, foi desenvolvido um modelo de transporte solucionado com o uso de técnicas de programação linear cujas soluções a partir da minimização dos custos de transporte apontaram para o uso ou não da cabotagem. As rotas que apresentaram maiores ganhos econômicos têm como característica uma grande distância entre a fábrica e as concessionárias e uma proximidade dos portos de destino das concessionárias.This study aims to examine the feasibility of costal shipping of new cars by cabotage in Brazil, searching for an alternative system, since, currently, this transport is performed solely by road transportation. The use of cabotage as cargo transportation has increased since the enactment of the Modernization of Ports Law (Act 8630) in 1993. Since then, automobile makers started to undergo a decentralization process, moving away from the Southeast, and, therefore, requiring more efficient transport. To evaluate the economical feasibility of this alternative, a case study was established and data were collected from a specific auto maker. The auto maker has plants in the cities of Camaçari (BA) and São Bernardo do Campo (SP) and needs to distribute its production to 275 authorized dealers across the country. From the study and analysis regarding road and cabotage costs for car transports, it was developed a transportation model whose solutions using linear programming techniques aim to mitigate transportation costs pointing to the use or not of cabotage. Routes that had greater economic yields are characterized by a large distance between the plant and dealers and proximity to destination ports of dealers.

Full textAbstract:
[Truncated abstract] Air pollution is increasingly perceived to be a serious intangible threat to humanity, with air quality continuing to deteriorate in most urban areas. The main sources of inner city pollution are motor vehicles, which generate emissions from the tail pipe as well as by evaporation. These contain toxic gaseous components which have adverse health effects. The major components are carbon monoxide (CO), nitrogen dioxide (NO2), nitric oxide (NO), sulphur dioxide (SO2), particulates (PM10), and volatile organic compounds (VOC). CO and oxides of nitrogen (NOx) are major emissions from cars. This study focuses on pollutant concentration in Perth city and has sought to develop measures to improve air quality. To estimate concentrations, the study develops air pollution models for CO and NOx; on the basis of the model estimates, effective policy is devised to improve the air quality by managing travel to the city. Two peaks, due to traffic, are observed in hourly CO and NOx concentrations. Unlike traffic, however, the morning peak does not reach the level of the afternoon peak. The reasons for this divergence are assessed and quantified. Separate causal models of hourly concentrations of CO and NOx explain their fluctuations accurately. They take account of the complex effects of the urban street canyon and winds in the city. The angle of incidence of the wind has significant impact on pollution level; a wind flow from the south-west increases pollution and wind from the north-east decreases it. The models have been shown to be equivalent to engineering and scientific models in estimating emission rate in the context of street canyons. However the study models are much more precise in the Perth context. ... The models are used to calculate the marginal effects for all attributes and elasticity for fuel price. In almost all attributes the non-work group is more responsive than the work group. Finally, the SP model results are integrated into an econometric model for the purpose of prediction. The travel behaviour prediction is used to estimate the policy impact on air quality. The benefit from the air quality improvement is reported in terms of life saved. The estimated relationships between probability of death and air pollution determines the number of lives that could be saved under various policy scenarios. A ratio of benefits to the financial and perceived sacrifices by drivers is calculated to compare the effectiveness of the suggested policies. A car size charge policy was found to be the most cost effective measure to ameliorate the environmental impact of cars in Perth, with a morning peak entry time charge being almost as cost effective. The study demonstrates the need for appropriate modelling of air pollution and travel behaviour. It brings together analytical methods at three levels of causality, vehicle to air pollution, charge to travel response, and air pollution to health.

[Truncated abstract] The main objective of this study was to develop and validate a demographic/epidemiologic Markov model for population modelling/forecasting of CARPs as well as CHD deaths and incidence in Western Australia using population, linked hospital morbidity and mortality data for WA over the period 1980 to 2000. A key feature of the model was the ability to count events as individuals moved from one state to another and an important aspect of model development and implementation was the method for estimation of model transition probabilities from available population data. The model was validated through comparison of model predictions with actual event numbers and through demonstration of its use in producing forecasts under standard extrapolation methods for transition probabilities as well as improving the forecasts by taking into account various possible changes to the management of CHD via surgical treatment changes. The final major objective was to demonstrate the use of model for performing sensitivity analysis of some scenarios. In particular, to explore the possible impact on future numbers of CARPs due to improvements in surgical procedures, particularly the introduction of drug eluting stents, and to explore the possible impact of change in trend of CHD incidence as might be caused by the obesity epidemic. ... When the effectiveness of PCI due to introduction of DES was increased by reducing Pr(CABG given PCI) and Pr(a repeat PCI), there was a small decline in the requirements for PCIs and the effect seemed to have a lag. Finally, in addition to these changes when other changes were incorporated which captured that a PCI was used more than a CABG due to a change in health policy after the introduction of DES, there was a small increase in the requirements for PCIs with a lag in the effect. Four incidence scenarios were developed for assessing the effect of change in secular trends of CHD incidence as might be caused by the obesity epidemic in such a way that they gradually represented an increasing effect of obesity epidemic (assuming that other risk factors changed favourably) on CHD incidence. The strategy adopted for developing the scenarios was that based on past trends the most dominant component of CHD incidence was first gradually altered and finally the remaining components were altered. iv The results showed that if the most dominant component of CHD incidence, eg, Pr(CHD - no history of CHD) levelled off and the trends in all other transition probabilities continued into future, then the projected numbers of CABGs and PCIs for 2001-2005 were insensitive to these changes. Even increasing this probability by as much as 20 percent did not alter the results much. These results implied that the short-term effect on projected numbers of CARPs caused by an increase in the most dominant component of CHD incidence, possibly due to an ?obesity epidemic, is small. In the final incidence scenario, two of the remaining CHD incidence components-Pr(CABG - no history of CHD) and Pr(CHD death - no CHD and no history of CHD) were projected to level off over 2001-2005 because these probabilities were declining over the baseline period of 1998-2000. The projected numbers of CABGs were more sensitive (compared to the previous scenarios) to these changes but PCIs were not.

Through the use of statistical techniques, this paper aims to present the behavior of credit card consumers, as well as to add value to the process of strategical marketing in a financial institution. For doing so, we present methodologies based on the techniques of logistical regression and survival analysis. Such tools are capable of foreseeing the behavior of customers, and thus focus on certain strategies in order to place resources that may hinder their migration to other financial institutions. The use of survival analysis methods makes it possible to analyze which variant presents evidence of customer migration; the logistical regression technique will be used in order to compare and validate the models hereby proposed, besides showing whether there are other variants that also demonstrate the closing of credit card accounts by the customers.

A crescente preocupação ambiental e a necessidade de se criar produtos mais eficientes têm impulsionado os pesquisadores a realizarem estudos acerca da aerodinâmica veicular. Estes dois fatores constituem os principais motivos, pelos quais existe uma grande procura por conhecimento nesta área. Esta ciência pode ser considerada relativamente nova e ainda carece de uma base de dados. Entender como a aerodinâmica se relaciona com o consumo de combustível nos automóveis, à medida que o arrasto impõe resistência ao deslocamento dos mesmos, é algo que tem estimulado as indústrias automotivas a investirem grandes esforços na obtenção de ferramentas, que possam representar as condições de tráfego normais e, assim conseguir prever o desempenho do produto em desenvolvimento. Os túneis de vento e a simulação computacional surgem neste ambiente como as principais ferramentas de análise e predição do escoamento ao redor do veículo. Por isso seu entendimento faz-se de extrema necessidade. Ter conhecimento sobre a concepção do seu projeto, como funcionam, seus pontos fortes e suas fraquezas, são requisitos necessários para a pessoa que deseja estudar esta ciência. O presente trabalho traz uma contextualização histórica da aerodinâmica veicular nas indústrias automotiva e automobilística, além de apresentar aspectos técnicos relacionados aos túneis de vento e simulação computacional. Abordando as vantagens e desvantagens de cada ferramenta, expõe-se o fato de que estas ferramentas são complementares no estudo aerodinâmico. Para exemplificar a utilização dessas ferramentas, foi realizado um estudo aerodinâmico sobre uma geometria básica, que representa com similaridade os veículos tipo hatchback, denominada Modelo SAE em ambiente computacional. Os conceitos acerca do arrasto veicular e estabilidade veicular foram expostos para embasar este estudo. Este modelo foi submetido a diferentes geometrias traseiras e condições de escoamento simétricas e assimétricas. Este estudo demonstrou que o arrasto e a estabilidade veicular compreendem conceitos distintos e, dessa forma, é possível diminuir o arrasto de um veículo sem haver perda de estabilidade.The growing environmental concern and the necessity to create more efficient products have motivated researchers to conduct studies about the aerodynamic vehicle. These two aspects are the main reasons which are promoting a great demand for knowledge in this theme. This science may be considered relatively new and still lacks more databases. Understand how aerodynamics is related to automobiles fuel consumption such as drag resistance imposed to their displacement, is something that has made the automotive industries invest considerable effort in obtaining tools which may represent the normal traffic conditions and thus, able to predict the performance of the product in development stage. The wind tunnels and computer simulations appear in this environment as the main tools for analysis and prediction of the flow around vehicle. The understanding about them is so of utmost necessity. Knowing how it was designed, how they work, their strengths and weaknesses are essential requirements for the person who wants to study this science. This material presents a historical development of vehicle aerodynamics in automotive and motor-racing industries, indeed technical aspects related to wind tunnels and computational fluid dynamics. Exposing the advantages and disadvantages of both tools, it is evidenced these tools complement each other during an aerodynamic study. To exemplify these tools utility an aerodynamic research was conducted using a basic form geometry known as SAE Model that represents with similarity the hatchback vehicles in the market. Drag and vehicle stability concepts were exposed to build a solid basis for this study. This model was submitted to different rear geometries, symmetric and asymmetric flow conditions. It could be demonstrated that drag and vehicle stability have distinct concepts and therefore it is possible diminish the first without damaging the later.

Os modelos de regressão beta e beta inflacionados conseguem ajustar adequadamente grande parte das variáveis do tipo proporção. No entanto, esses modelos não são úteis quando a variável resposta não pode assumir valores no intervalo (0,c) e assume o valor c com probabilidade positiva. Variáveis relacionadas a algum tipo de pagamento limitado entre dois valores, quando estudadas em relação ao seu valor máximo, possuem essas características. Para ajustar essas variáveis, introduzimos a distribuição beta inflacionada truncada (BIZUT), que é uma mistura de uma distribuição beta com suporte no intervalo (c,1) e uma distribuição trinomial que assume os valores zero, um e c. Propomos ainda um modelo de regressão para as situações em que a variável resposta tem distribuição BIZUT. Admitimos que todos os parâmetros da distribuição podem variar em função de variáveis preditoras. Além disso, o modelo permite que o parâmetro conhecido c varie entre as unidades populacionais. Para esse modelo são desenvolvidos diversos aspectos inferenciais, são obtidos resultados para as situações em que c é variável e são conduzidos estudos de simulação de Monte Carlo. Além disso, discutimos análise de resíduos, desenvolvemos análise de influência local e realizamos uma aplicação a dados reais de cartão de crédito.The beta regression model or the inflated beta regression model may be a reasonable choice to fit a proportion in most situations. However, they do not fit well variables that do not assume values in the open interval (0,c), 0 < c < 1 and assume the c value with positive probability. Variables related to a kind of double bounded payment amount when studied as a proportion of the maximum payment amount have this feature. For these variables, we introduce the truncated inflated beta distribution (TBEINF). This proposed distribution is a mixture of the beta distribution bounded in the open interval (c,1) and a trinomial distribution that assumes the values zero, one and c. This work also proposes a regression model where the response variable is TBEINF distributed. The model allows all the unknown parameters of the conditional distribution of the response variable to be modeled as functions of explanatory variables. Moreover, the model allows nonconstant known parameter c across population units. For this model, some inferential aspects are developed, some results when c is not constant are obtained and Monte Carlo simulation studies are performed. In addition, residual and local influence analysis are discussed and an application to credit card data is presented.

Full textAbstract:
Un des plus grands défis dans la conception matérielle et logicielle est de s’assurer que le système soit exempt d’erreurs. La moindre erreur dans les systèmes embarqués réactifs peut avoir des conséquences désastreuses et coûteuses pour certains projets critiques, nécessitant parfois de gros investissements pour les corriger, ou même conduire à un échec spectaculaire et inattendu du système. Prévenir de tels phénomènes en identifiant tous les comportements critiques du système est une tâche assez délicate. Les tests en industrie sont globalement non exhaustifs, tandis que la vérification formelle souffre souvent du problème d’explosion combinatoire. Nous présentons dans ce contexte une nouvelle approche de génération exhaustive de jeux de test qui combine les principes du test industriel et de la vérification formelle académique. Notre approche construit un modèle générique du système étudié à partir de l’approche synchrone. Le principe est de se limiter à l’analyse locale des sous-espaces significatifs du modèle. L’objectif de notre approche est d’identifier et extraire les conditions préalables à l’exécution de chaque chemin du sous-espace étudie. Il s’agit ensuite de générer tout les cas de tests possibles à partir de ces pré-conditions. Notre approche présente un algorithme de quasi-aplatissement plus simple et efficace que les techniques existantes ainsi qu’une compilation avantageuse favorisant une réduction considérable du problème de l’explosion de l’espace d’états. Elle présente également une manipulation symbolique des données numériques permettant un test plus expressif et concret du système étudiéOne of the biggest challenges in hardware and software design is to ensure that a system is error-free. Small errors in reactive embedded systems can have disastrous and costly consequences for a project. Preventing such errors by identifying the most probable cases of erratic system behavior is quite challenging. Indeed, tests in industry are overall non-exhaustive, while formal verification in scientific research often suffers from combinatorial explosion problem. We present in this context a new approach for generating exhaustive test sets that combines the underlying principles of the industrial test technique and the academic-based formal verification approach. Our approach builds a generic model of the system under test according to the synchronous approach. The goal is to identify the optimal preconditions for restricting the state space of the model such that test generation can take place on significant subspaces only. So, all the possible test sets are generated from the extracted subspace preconditions. Our approach exhibits a simpler and efficient quasi-flattening algorithm compared with existing techniques and a useful compiled internal description to check security properties and reduce the state space combinatorial explosion problem. It also provides a symbolic processing technique of numeric data that provides a more expressive and concrete test of the system. We have implemented our approach on a tool called GAJE. To illustrate our work, this tool was applied to verify an industrial project on contactless smart cards security

The development of IT has enabled the Internet of Things. Internet of Things is connected devices that communicate with each other and generate data that can then be used for different purposes. The number of connected devices is estimated to 20.4 billion by year 2020. The technology allows the automotive industry to connect its vehicles, which is called Internet of Vehicles, an application of the Internet of Things and intelligent cars. The amount of scientific literature that addresses the economic aspects related to the Internet of Things is scarce and need to be investigated further. The connected car is a disruptive technology that is expected to affect the automotive industry and their business models radically in the next few years and nobody really knows how the industry may look like the next 10-15 years. This type of disruptive technology requires companies to have the competence to implement innovative business models. The study focuses on the connected car from a business perspective and makes no insight into technical aspects or security challenges. The purpose of the study is to create an under-standing of the challenges facing the automotive business models with the introduction of the Internet of Things, which gives the automotive industry the opportunity to connect their cars to a greater extent than before. The study's results show that the value proposition and the channels are the most important parts to focus on in the business model. In order for companies to capitalize on the connection, it is extremely important that the customers understand the value of the connection and that the companies properly manage the information derived from the connected cars. Today, companies offer services or increased value in existing business models to strengthen their brand. The respondents share the opinion that the traditional business models will not change radically as long as the ownership of the car stay the same. Ownership and autonomous cars are the factors that are expected to affect the automotive industry the most. According to the respondents in the study, in order to deal with disruptive innovations in the industry, courage, adaptability, prospects and innovative thinking are required.IT-utvecklingen har möjliggjort sakernas internet, Internet of Things. Internet of Things är uppkopplade enheter som kommunicerar med varandra och genererar data som sedan kan användas i olika syften. Antalet anslutna enheter beräknas att uppgå till 20,4 miljarder år 2020. Tekniken ger bilindustrin möjligheten att koppla upp sina fordon vilket benämns som Internet of Vehicles, en applikation av Internet of Things och intelligenta bilar. Vetenskaplig litteratur som tar upp de ekonomiska aspekterna i relation till Internet of Things är begränsad och behöver undersökas i större utsträckning. Den uppkopplade bilen är en disruptiv teknologi som förväntas påverka bilindustrin och deras affärsmodeller radikalt inom de närmaste åren och det är ingen som riktigt vet hur industrin kan komma att se ut de närmsta 10-15 åren. Denna typ av disruptiv teknologi kräver att företagen har kompetensen att implementera innovativa affärsmodeller. Studien fokuserar på den uppkopplade bilen ur ett affärsperspektiv och gör ingen fördjupning i tekniska aspekter eller säkerhetsutmaningar. Syftet med studien är att skapa förståelse för vilka utmaningar bilindustrins affärsmodeller står inför med introduktionen av Internet of Things som ger industrin möjligheten att koppla upp sina bilar i en större omfattning än tidigare. Studiens resultat visar att värdeerbjudandet och kanalerna är de viktigaste delarna att fokusera på i affärsmodellen. För att företagen ska kunna kapitalisera på uppkopplingen är det viktigt att kunderna förstår värdet av uppkoppling och att företagen förvaltar informationen från de uppkopplade bilarna på rätt sätt. Idag erbjuder företagen tjänster eller utökat värde i befintlig affärsmodell för att stärka sitt varumärke. Respondenterna delar uppfattningen om att de traditionella affärsmodellerna inte kommer förändras radikalt så länge ägandet av bilen inte gör en helomvändning. Ägandeskapet och autonoma bilar är de faktorer som förväntas påverka industrin störst. Respondenterna i studien nämner fyra viktiga egenskaper för att kunna hantera disruptiva innovationer i branschen, mod, anpassningsbarhet, framtidsutsikt och nytänkande.

This diploma thesis deals with design, realization and analysis of security and surveillance systems for buildings and spaces containing advanced components. One of the main design's parts is dedicated to intruder alarm system, access system, attendance and CCTV systems with the possibility of automatic motion tracking. Controlling and monitoring of particular subsystems is possible both locally and remotely from a computer via a web interface or by means of a software. The access to camera system from a mobile phone is also possible. IAS/ACS systems also enable controlling and transferring information about their state via SMS. The designed system was realized completely and its operating was demonstrated. The realization is described in detail including illustration of configuration of particular components. A security analysis and a possible future development of the project is summarized in the conclusion.
