Abstract:
Cas clinique : Une jeune femme de 26 ans a été traitée par chimiothérapie puis chirurgie lourde et chimiothérapie adjuvante pour un sarcome d’Ewing des tissus mous envahissant l’aile iliaque droite. Elle a nécessité des opioïdes forts par voie intraveineuse pendant la période de traitement, et ceux-ci ont été poursuivis plusieurs mois après, avec des effets secondaires sévères, à type de syndrome de manque, de somnolence et d’impossibilité de réinvestir la vie quotidienne. Un relais par méthadone per os a permis une levée des effets secondaires très rapide, une réinsertion familiale et professionnelle et sevrage complet en quelques mois sans reprise des douleurs. Discussion : Les opioïdes forts sont le traitement de référence de la douleur intense en oncologie, et le recours à la voie parentérale est justifié si le contrôle per os est insuffisant. Il est cependant impératif de revenir à une voie orale et de réduire progressivement les doses dès que l’étiologie de la douleur est contrôlée, au risque sinon d’induire des effets délétères potentiellement sévères, tant médicaux que psychosociaux.

Abstract:
L’une des caractéristiques des équipements électroménagers est qu’ils consomment également de l’énergie en mode veille, ce qui peut prendre des quantités considérables dans le temps. Un système intelligent capable de couper automatiquement l'alimentation électrique de l'équipement en mode veille doit être important pour réduire la consommation électrique et les dépenses financières. Pour concevoir le système, la consommation électrique en mode veille de 3 équipements ménagers de base a été mesurée dans un premier temps. En un mois, la consommation totale d'énergie mesurée en mode veille était de 28,31 kWh. Ensuite, les fonctions du système, basées sur le microcontrôleur Arduino Nano, ont pour rôle de contrôler l'état d'un module relais, qui est donné par le courant consommé par l'équipement. Le contrôle du système s'effectue à l'aide d'une application développée pour les appareils du système d'exploitation Android, qui peut être utilisée pour définir la valeur du courant de temporisation et activer/désactiver manuellement le système. En mettant en œuvre le système proposé sur les 3 équipements domestiques mesurés précédemment, la consommation d'énergie en mode veille est réduite de 19,83 kWh par mois.

OBJETIVOS: Avaliar qual técnica de alongamento muscular confere maior ganho de flexibilidade dos músculos isquiotibiais. MÉTODO: Sessenta voluntários de ambos os sexos, com idade entre 18 e 29 anos foram divididos aleatoriamente em seis grupos: G0 – grupo controle, G1 – alongamento estático por 1 minuto; G3 – alongamento estático por 3 minutos; G5 – alongamento estático por 5 minutos; FNP3 – 3 séries de alongamento hold-relax e FNP6 – 6 séries hold-relax. A amplitude de movimento de extensão ativa do joelho foi avaliada antes e após cada sessão e antes e dois dias após término do treinamento, que foi realizado por cinco dias consecutivos. Para a análise dos dados foram utilizados os testes ANOVA post hoc Newman-Keuls. RESULTADOS: Verificou-se que somente os voluntários dos grupos G3, G5 e FNP6 apresentaram ganhos significativos de flexibilidade em relação ao grupo controle. CONCLUSÕES: Os resultados sugerem que independente da técnica aplicada, o tempo de manutenção parece ser o fator chave para o ganho de flexibilidade, devendo este ser de no mínimo três minutos.

Abstract:
A brief historical survey of the u.s. export controls on strategic goods indicate the importance of the Cold War in achieving these objectives as well as the importance of polycentrism across and within the institutions and agencies concerned. The proliferation of controls has brought about a large area of freedom for the implementation of foreign policy by the executive branch of the Government. After the end of the Cold War, one can surmise that the emphasis mil be felt at three different levels : a greater discretion by national actors in the implementation of export controls policy, a greater harmonization of multilateral efforts designed at promoting the nonproliferation of weapons of mass destruction, and greater cleavages between those who want to relax export controls for economic reasons and those who want to strengthen them for security reasons. On the whole, the multiplicity of legislative actions and organizations concerned can only reinforce the freedom of action of the executive branch of the Government.

RÉSUMÉ La notion de puissance paternelle héritée de la Coutume de Paris et fondée sur le mariage est intégrée au Code civil de 1866. Elle fait place, en 1977, à celle d'autorité parentale, fondée sur la filiation et susceptible de déchéance. Les bouleversements que connaît la société québécoise entre ces deux dates transforment la perception sociale de l'enfant et les modes de contrôle des comportements parentaux. L'État, à travers l'appareil judiciaire et administatif, prend à cet égard le relais de l'Église, autrefois omniprésente. L'intérêt de l'enfant et plus tard ses droits fondent et orientent les interventions de l'État à son égard.

Abstract:
Primary hypoadrenocorticism or Addison’s disease is an endocrinopathy involving glucocorticoid deficiency, commonly associated with mineralocorticoid deficiency. The most commonly used treatment for hormone replacement involves the combination of fludrocortisone and prednisone. Deoxycorticosterone pivalate (DOCP) has been shown in the literature to be superior in electrolyte control in patients with hypoadrenocorticism, and should always be associated with prednisone/prednisolona. In this study, we report the benefit of DOCP and the two-stage dose adjustment protocol for this drug in 2 different cases. There was superior efficacy in electrolyte control and reduction of side effects with the DOCP and prednisolone protocol compared to the use of fludrocortisone in both patients.

En la última década los poderes públicos han fomentado el uso de los permisos parentales por parte de los hombres como un nuevo mecanismo para fomentar la igualdad de género y la no discriminación por razón de maternidad. En este trabajo se analiza a partir de la encuesta europea de condiciones de trabajo de 2005, recurriendo a la submuestra correspondiente a padres de hijos menores de 8 años, si efectivamente el uso de los permisos parentales por los hombres se traduce en una mayor implicación en el cuidado de sus hijos y en el trabajo doméstico. A partir de un análisis de regresión logística en el que se controla por distintas características del trabajo, la situación familiar y el nivel educativo, los resultados confirman que los hombres que han hecho uso del permiso parental en el año previo a la encuesta están más frecuentemente implicados en el cuidado diario de los niños y en la realización del trabajo doméstico que quienes no han hecho uso de esta posibilidad. El uso por los hombres del permiso parental se evidencia así como un mecanismo que promueve su socialización en las tareas de cuidado no remunerado.

Abstract:
Nous considérons les équations différentielles stochastiques (EDS) de Mc Kean-Vlasov, qui sont des EDS dont les coefficients de dérive et de diffusion dépendent non seulement de l'état du processus inconnu, mais également de sa loi de probabilité. Ces EDS, également appelées EDS à champ moyen, ont d'abord été étudiées en physique statistique et représentent en quelque sorte le comportement moyen d'un nombre infini de particules. Récemment, ce type d'équations a suscité un regain d'intérêt dans le contexte de la théorie des jeux à champ moyen. Cette théorie a été inventée par P.L. Lions et J.M. Lasry en 2006, pour résoudre le problème de l'existence d'un équilibre de Nash approximatif pour les jeux différentiels, avec un grand nombre de joueurs. Ces équations ont trouvé des applications dans divers domaines tels que la théorie des jeux, la finance mathématique, les réseaux de communication et la gestion des ressources pétrolières. Dans cette thèse, nous avons étudié les questions de stabilité par rapport aux données initiales, aux coefficients et aux processus directeurs des équations de McKean-Vlasov. Les propriétés génériques de ce type d'équations stochastiques, telles que l'existence et l'unicité, la stabilité par rapport aux paramètres, ont été examinées. En théorie du contrôle, notre attention s'est portée sur l'existence et l'approximation de contrôles relaxés pour les systèmes gouvernés par des EDS de Mc Kean-Vlasov
We consider Mc Kean-Vlasov stochastic differential equations (SDEs), which are SDEs where the drift and diffusion coefficients depend not only on the state of the unknown process but also on its probability distribution. These SDEs called also mean- field SDEs were first studied in statistical physics and represent in some sense the average behavior of an infinite number of particles. Recently there has been a renewed interest for this kind of equations in the context of mean-field game theory. Since the pioneering papers by P.L. Lions and J.M. Lasry, mean-field games and mean-field control theory has raised a lot of interest, motivated by applications to various fields such as game theory, mathematical finance, communications networks and management of oil resources. In this thesis, we studied questions of stability with respect to initial data, coefficients and driving processes of Mc Kean-Vlasov equations. Generic properties for this type of SDEs, such as existence and uniqueness, stability with respect to parameters, have been investigated. In control theory, our attention were focused on existence, approximation of relaxed controls for controlled Mc Kean-Vlasov SDEs

O teste de Thomas é utilizado nas áreas clínica e desportiva para determinar o encurtamento do ilíopsoas e do reto femoral, músculos constituintes do core. O encurtamento destes músculos é um dos fatores de risco de lesão músculo-esquelética nos membros inferiores e de dor lombar. A técnica de suster-relaxar, aumenta a amplitude de movimento articular, normalizando o tónus muscular. Objetivo: Avaliar o efeito da técnica de suster-relaxar na cinemática tridimensional do teste de Thomas, na função neuromuscular e sintomatologia álgica de um atleta de crossfit com dor lombar à direita. Metodologia: Análise da cinemática tridimensional do teste de Thomas através do sistema de captura e análise de movimento 3D, Qualisys Oqus Camera Series, e força isocinética dos joelhos pela dinamometria isocinética, antes e após a aplicação técnica suster-relaxar num atleta de crossfit de 25 anos. Resultados: Após a análise dos dados obtidos, verificou-se um aumento da amplitude de extensão da anca, do peak torque e diminuição da sintomatologia álgica, no lado afetado do atleta, em resultado da aplicação da técnica de suster-relaxar. Conclusão: A técnica suster-relaxar aumenta a amplitude de movimento articular, e o peak torque e diminui a sintomatologia de dor lombar associado a uma disfunção sacroilíaca num atleta de crossfit.
Introduction: Low back pain is associated with changes in muscle activity and lumbar- pelvic kinematics caused, partly by the weakness of the core musculature. The Thomas test is widely used in clinical and sports areas to determine the shortening of the iliopsoas and rectus femoris, core constituent muscles. The shortening of these muscles is one of the risk factors for musculoskeletal injury in the lower limbs and back pain. The technique of hold-relax, increases range of motion, normalizing muscle tone. Objective: To access the effect of the hold-relax technique in the three-dimensional kinematics of the Thomas test, neuromuscular function and symptoms of a crossfit athlete with right low back pain. Methodology: Analysis of three-dimensional kinematics of the Thomas test through the capture system and 3D motion analysis, Qualisys Oqus Camera Series, and isokinetic strength of the knee by isokinetic dynamometer before and after the hold-relax technique application in a 25 years crossfit athlete. Results: After analysing the data, there was an increase in hip extension range, peak torque and reduction of pain symptoms on the affected side of the athlete, as a result of the technical application of hold-relax. Conclusion: The hold-relax technique increases range of motion andpeak torque and decreases lumbar pain symptoms associated with a sacroiliac dysfunction in a crossfit athlete.

Abstract:

Enics Sweden AB, Västerås, is an electronics manufacturing services company with its main business in manufacturing electronics. Most, if not all, electronic devices that are manufactured are being widely tested before delivery to ensure proper functionality. Often during tests a large number of signals are measured by one to a few digital multimeters and are therefore controlled through relays. Relays are also used when applying stimuli with high currents or voltages to the unit under test.

This work have been focused on finding a concept, including designing and producing a prototype, for a modular relay control system for use in fabrication of small test systems and for use when there is a need for adding more relays to an existing system.

Abstract:
This thesis performs simulations of a relay supervisory system (RSS) that works passively in conjunction with the existing protective relaying system at a substation. During normal system operating conditions, the RSS supervises the relay system to prevent trips due to hidden failures. During wide area network disturbances, it adapts the relay system to increase security of the power system. The RSS works passively in the sense that it waits for events to occur in the existing relay system before taking any action. The simulation performed includes a model of the RSS, along with simplified models of existing relays, performed in Matlab. A power system model in EMTP provides inputs to the RSS model. Multiple faults are applied to the EMTP model, and the RSS is tested under each fault condition, and with a variety of relay hidden failures. For all tests performed, the simulation of the RSS successfully prevents relay hidden failure from removing circuit elements inadvertently, while allowing correct relay operations to remove circuit elements.

Abstract:
The aim of this thesis is to investigate relay feedback process identification and some controller design methods. Using an exact analysis method, namely the state space method, a set of conditions for the prediction of oscillations in relay control systems has been developed. Since the exact solution for the limit cycle is found it becomes possible to assess the stability of these oscillations using an eigenvalue criterion. A correction factor has been introduced to overcome the limitations of the Balasubramanian's eigenvalue criterion. Relay feedback identification in process control can lead to erroneous results if the system parameters are estimated from the approximate describing function approach. Exact analytical expressions are derived and on the basis of these expressions an identification procedure is suggested which is capable of estimating the parameters of a class of process transfer functions. Analytical expressions are presented for quantifying the approximate estimation errors in the presence of measurement noise and load disturbance. The performance limitations of the conventional PID controller have been clearly shown in the context of controlling resonant, unstable or integrating processes. It has been shown that a PI-PD controller with the PD in the inner loop not only avoids the derivative kick but also a better performance is achieved than with a P or D controller in the inner loop. Further, the same controller provides good disturbance rejection and its performance is often near to that of an optimum controller for disturbance rejection and is significantly better than the results of other design methods based on setpoint response. Simple tuning methods based on standard forms for a PI-PD controller controlling time delay processes have been presented which are particularly effective for integrating and unstable plants. Automatic tuning formulae for PI, PID and PI-PD controllers have been proposed for controlling stable and unstable processes. The problem of controlling integrating and unstable processes incorporating time delay has been tackled by proposing a new Smith predictor. It is shown that the predictor is capable of successfully controlling stable, integrating and unstable processes. Controller parameters leading to robust performance for various levels of uncertainty in the model parameters particularly in the unstable time constant and time delay have been presented. Also, simple and effective automatic tuning formulae are derived for the new Smith predictor structure when the plant model is not available assuming first order model with time delay for stable, unstable and integrating processes. The plant model blocks in the control structure, as well as all the controllers, are designed from a single symmetrical relay test.

Abstract:
The increasing popularity of wireless communications and the higher data requirements of new types of service lead to higher demands on wireless networks. Relay based cellular networks have been seen as an effective way to meet users’ increased data rate requirements while still retaining the benefits of a cellular structure. However, maximizing the probability of providing service and spectrum efficiency are still major challenges for network operators and engineers because of the heterogeneous traffic demands, hard-to-predict user movements and complex traffic models. In a mobile network, load balancing is recognised as an efficient way to increase the utilization of limited frequency spectrum at reasonable costs. Cooperative control based on geographic load balancing is employed to provide flexibility for relay based cellular networks and to respond to changes in the environment. According to the potential capability of existing antenna systems, adaptive radio frequency domain control in the physical layer is explored to provide coverage at the right place at the right time. This thesis proposes several effective and efficient approaches to improve spectrum efficiency using network wide optimization to coordinate the coverage offered by different network components according to the antenna models and relay station capability. The approaches include tilting of antenna sectors, changing the power of omni-directional antennas, and changing the assignment of relay stations to different base stations. Experiments show that the proposed approaches offer significant improvements and robustness in heterogeneous traffic scenarios and when the propagation environment changes. The issue of predicting the consequence of cooperative decisions regarding antenna configurations when applied in a realistic environment is described, and a coverage prediction model is proposed. The consequences of applying changes to the antenna configuration on handovers are analysed in detail. The performance evaluations are based on a system level simulator in the context of Mobile WiMAX technology, but the concepts apply more generally.

Abstract:
Nous assistons ces dernières années à une émergence constante de nouvelles applications, notamment pour les services audiovisuels. Ces applications imposent au réseau un certain nombre de contraintes pour qu’elles puissent fonctionner correctement. Le développement de mécanismes permettant d’offrir une garantie à ces contraintes, est donc devenu un objectif crucial. La norme IEEE 802.16j est l’une des solutions sans fil qui propose plus de ressources afin de supporter les nouveaux services de télécommunications. Dans la présente thèse, nous focalisons notre étude sur la problématique de la qualité de service dans les réseaux WiMAX relais. Nos contributions se regroupent à travers les étapes ci-dessous : Nous proposons un protocole de routage multicast pour les services IPTV (HDTV, SD-TV, Web-TV et Mobile-TV). Ce protocole repose d’une part sur un nouveau mécanisme de construction de l’arbre multicast basé sur les nombres premiers et d’autre part, sur une nouvelle méthode d’agrégation basée sur le standard de compression Vidéo «SVC». L’objectif est de supporter l’hétérogénéité des utilisateurs tout en optimisant la consommation des ressources. Par ailleurs, nous étudions le problème d’ordonnancement dans les réseaux WiMAX. Nous proposons un algorithme d’ordonnancement adaptatif AWRR, ce dernier se base sur une technique à charge pondérée. L’objectif est d’ajuster dynamiquement le poids de chaque classe de service, en prenant en compte la charge de la file d’attente et les contraintes de la QoS. Enfin, nous nous intéressons à l’étude de la problématique du chemin optimal contraint. Nous proposons une solution déterministe basée sur une fonction de coût. Notre fonction permet aussi d’assurer le contrôle d’admission, elle se base sur deux fonctions de coût élémentaires qui prennent en compte quatre critères de QoS
Over recent years, new applications steadily developed in a tremendous space, especially in audiovisual services area. The present applications have some of constraints to work properly. The developments of mechanism which enable to overcome these constraints become a critical issue in this area. The IEEE 802.16j standard is one of wireless communication technology which offering more resources to support new telecommunication services. In this thesis, we focus our research on the problem of quality of service (QoS) inWiMAX relay networks. Our contributions are classified as follows : we proposed a multicast routing protocol for IPTV services (such as HD-TV, SD-TV, Web-TV and Mobile-TV). This proposed protocol used a new multicast tree construction mechanism based-on prime numbers. We also developed a new aggregation method based on standard video compression called Scalable Video Coding (SVC). Our goal is to support user’s heterogeneity while optimizing resources consumption. In addition, we studied the problem of scheduling inWiMAX networks.We proposed an adaptive scheduling algorithm AWRR for IPTV services. The aim of this method is to support QoS constraints by using two schedulers, and assigning a dynamic value to each service queue. Finally, we interested to study about the problem of path selection. We proposed a solution based on a deterministic cost function. This function also ensures admission control based on two basic cost functions which include four QoS criteria. This thesis has been prepared in the MIPS/GRTC laboratory, University of Haute Alsace, under a research contract external (CRE) framework with France Telecom R&D. All proposed mechanisms were evaluated by the simulator QualNet, Matlab and mathematical analysis

Full text
Abstract:
An adaptive nonlinear stabilizer is introduced for uncertain, voltage-controlled, microelectromechanical system (MEMS) relays. The control construction follows a Lyapunov approach, and is based on a nonlinear dynamic model applicable to the two types of MEMS relays—electrostatic and electromagnetic. The adaptive stabilizer compensates for parametric uncertainty in all mechanical parameters and selected electrical parameters while ensuring asymptotic regulation of the electrode opening and closing. Simulations demonstrate the performance of the adaptive control scheme in comparison to the typical open-loop operation of the MEMS relay.

Abstract:
A number of microprocessor-based digital devices with communication capabilities have been manufactured for traction power substations. These devices include protective relays, fault recorders, and metering units. One such device is the SIEMENS SITRAS DPU96 relay that provides over-current and rate-of-rise protection for faults on DC traction power distribution system. To fully utilize this digital technology, Programmable Logic Controller (PLC) was the best mean of collecting and organizing data from these devices locally at the traction power substation and also provide easy interface with the SCADA system. PLC was also used for high rail-to-earth potential monitoring and protection. The trip characteristics of this relay require adjustability over the voltage ranges normally from 40Vdc to 160Vdc and time-delay range from 10ms to 3 seconds which can be easily accomplished with PLC programming. This paper describes the applications of digital relays, human machine interface (HMI), and PLC in a traction power substation.

Abstract:
RELAP/SCDAPSIM, designed to predict the behavior of reactor systems during normal and accident conditions, is being developed as part of the international SCDAP Development and Training Program (SDTP). RELSIM, an advanced interactive simulator Graphical User Interface, is a commercially available package being developed by Risk Management Associates (RMA). The combined package, RELSIM-RELAP/SCDAPSIM, is being used for training of university students and other novice reactor systems analysts to help them understand how complex thermal hydraulic and/or reactor systems perform under realistic and postulated conditions. RELAP/SCDAPSIM uses internationally developed and validated system thermal hydraulic, fuel behavior, and severe accident models in combination with a flexible building block approach to model thermal hydraulic and reactor systems. RELSIM also uses a building block approach and user defined graphics screens in combination with the ability to interactively control the RELAP/SCDAPSIM simulation. As a result, students and analysts can use the package to describe both simple and complex thermal hydraulic systems ranging from simple pipes and university-scale experimental facilities up through current and conceptual reactor systems. This paper gives a brief description of the RELSIM-RELAP/SCDAPSIM package and then provides a discussion of how the package is being used for student and analyst training, The discussion includes the development of training tutorials and videos for novice users, the development of representative sample problems and graphics displays, and the type of training provided to support the users. A case study is presented in the paper outlining the sample problems and displays for use in novice RELAP5 and RELAP/SCDAPSIM user training classes.

Full text
Abstract:
This working paper critically examines Ayelet Shachar’s (2020) concept of the ‘shifting border’ and the solutions she proposes to tackle this recent phenomenon, pointing out potential gaps, inconsistencies and unintended consequences of letting legal responsibility follow states’ ‘shifting borders’. Instead, the paper argues for the need to deterritorialize the right to asylumin order to prevent states from retracting back from or shifting out their responsibilities for refugees and migrants, and to question and ultimately relax our current state-imposed mobility controls which have come to be largely taken for granted, even among migration and border scholars.

Full text
Abstract:
The final portfolio contains 8 research articles from national and international journals. Study designs include one systematic review, one randomized control trial with pretest-posttest design, three small-scale randomized control trials, one quasi-experimental study with no control, one time-series study, and one case study. All studies relate directly to components of the evidence-based practice question and will be used to draft new recommendations for implementation regarding spaced retrieval training for memory enhancement in adults with dementia. Seven out of the eight articles looked at the effects of SR techniques on functional tasks. Articles looked at eating difficulty (1), independent use of walkers (1), iADL function (3), use of technology (1), and ADL function (1). One out of eight articles looked at benefits of spaced retrieval techniques on episodic memory, which is not necessarily a functional task, but is needed to perform functional tasks.

Full text
Abstract:
Literature is reviewed for the impacts of variable natural gas composition on two-stroke lean burn pipeline compressor engines. Information gathered for these engines can be simplified for development of control algorithms in four-stroke and richer burning engines. Data shows that geospatial, geological, and transient hydraulic effects cause composition variations that adversely affect engine emissions, efficiency, rated performance, and operational safety considering auto-ignition effects. In order to compensate for these changes in composition, better engine control schemes can help meet desired performance goals. For specific gas compositions combusting at a fixed air-fuel ratio, the laminar flame speed, adiabatic flame temperature, and ignition delay relate to and allow the prediction of the mixture�s reactivity, thermal availability, and auto-ignition tendency. Predicting changes in these combustion parameters, as caused by changes in fuel composition, is essential to the success of control development for variable composition engine operation. In addition to addressing the associated combustion effects resulting from variable fuel composition, an overview of sensor technologies is presented for use in control applications.

Full text
Abstract:
The purpose of our critically appraised topic is to synthesize the highest-level evidence available regarding interventions for increasing confidence and mental health outcomes in caregivers taking loved ones home from inpatient rehabilitation. The final portfolio contains six research articles from peer-reviewed journals. Study designs include randomized control trials, a systematic review, and a pretest-posttest without a control group. All studies relate directly to the components of the PICO question. Four of the articles discussed both caregiver confidence and mental health while two articles discussed only mental health. There is strong evidence to support that in-person hands on training, in person discussion-based training, and/or virtual resources helped increase confidence in caregivers of patients. There is mixed evidence and only limited improvement to support mental health. The findings from this critically appraised topic will be used to draft new ideas for practice guidelines for addressing caregiver education and caregiver mental health in an inpatient rehabilitation facility.
