Etude de l'immunité des circuits intégrés face aux agressions électromagnétiques : proposition d'une méthode de prédiction des couplages des perturbations en mode conduit / Study of integrated circuits immunity against electromagnetic disturbances : proposal of a methodology which aims at predicting coupling of conducted disturbances

Deobarro, Mikaël 21 April 2011 (has links)
Avec les progrès technologiques réalisés au cours de ces dernières décennies, la complexité et les vitesses de fonctionnement des circuits intégrés ont beaucoup été augmentées. Bien que ces évolutions aient permis de diminuer les dimensions et les tensions d’alimentations des circuits, la compatibilité électromagnétique (CEM) des composants a fortement été dégradée. Identifiée comme étant un verrou technologique, la CEM est aujourd’hui l’une des principales causes de « re-design » des circuits car les problématiques liées aux mécanismes de génération et de couplage du bruit ne sont pas suffisamment étudiées lors de leur conception.Ce manuscrit présente donc une méthodologie visant à étudier la propagation du bruit à travers les circuits intégrés par mesures et par simulations. Afin d’améliorer nos connaissances sur la propagation d’interférences électromagnétiques (IEM) et les mécanismes de couplage à travers les circuits, nous avons conçu un véhicule de test développé dans la technologie SMOS8MV® 0,25 µm de Freescale Semiconductor. Dans ce circuit, plusieurs fonctions élémentaires telles qu’un bus d’E/S et des blocs numériques ont été implémentées. Des capteurs de tensions asynchrones ont également été intégrés sur différentes alimentations de la puce pour analyser la propagation des perturbations injectées sur les broches du composant (injection DPI) et sur les conducteurs permettant d’alimenter ce dernier (injection BCI). En outre, nous proposons différents outils pour faciliter la modélisation et les simulations d’immunité des circuits intégrés (extraction des modèles de PCB, approches de modélisation des systèmes d’injection, méthode innovante permettant de prédire et de corréler les niveaux de tension/ de puissance injectés lors de mesures d’immunité conduite, flot de modélisation). Chaque outil et méthode de modélisation proposés sont évalués sur différents cas test. Enfin, pour évaluer notre démarche de modélisation, nous l’appliquons sur un bloc numérique de notre véhicule de test et comparons les résultats de simulations aux différentes mesures internes et externes réalisées sur le circuit / With technological advances in recent decades, the complexity and operating speeds of integrated circuits have greatly increased. While these developments have reduced dimensions and supply voltages of circuits, electromagnetic compatibility (EMC) of components has been highly degraded. Identified as a technological lock, EMC is now one of the main causes of circuits re-designs because issues related to generating and coupling noise mechanisms are not sufficiently studied during their design. This manuscript introduces a methodology to study propagation of electromagnetic disturbances through integrated circuits by measurements and simulations. To improve our knowledge about propagation of electromagnetic interferences (EMI) and coupling mechanisms through integrated circuits, we designed a test vehicle developed in the SMOS8MV® 0.25µm technology from Freescale Semiconductor. In this circuit, several basic functions such as I/O bus and digital blocks have been implemented. Asynchronous on-chip voltage sensors have also been integrated on different supplies of the chip to analyze propagation of disturbances injected on supply pins and wires of the component (DPI and BCI injection). In addition, we propose various tools to facilitate modeling and simulations of Integrated Circuit’s immunity (PCB model extraction, injection systems modeling approaches, innovative method to predict and correlate levels of voltage / power injected during conducted immunity measurements, modeling flow). Each tool and modeling method proposed is evaluated on different test cases. To assess our modeling approach, we finally apply it on a digital block of our test vehicle and compare simulation results to various internal and external measurements performed on the circuit

Efeito da associação da triancinolona à viscossuplementação do joelho / Effect of the addition of corticosteroid to viscosupplementation of the knee

Gustavo Constantino de Campos 19 March 2014 (has links)
O presente estudo destinou-se a avaliar se os resultados clínicos iniciais da viscossuplementação poderiam ser melhorados com a adição de corticosteróide. As injeções intra-articulares são usadas há muitos anos no tratamento da osteoartrite dos joelhos, principalmente com suspensões cristalinas de corticosteróides. A viscossuplementação é uma intervenção relativamente nova, atualmente recomendada no tratamento da osteoartrite. Trata-se da injeção de ácido hialurônico exógeno em articulações diartrodiais, visando, além de restaurar as propriedades reológicas do líquido sinovial, efeitos modificadores da doença osteoartrite. Revisões sistemáticas mostram que a melhora clínica ocorre em duas a cinco semanas após a viscossuplementação. Comparando-se a viscossuplementação com a injeção intraarticular com corticosteróides, dados recentes sugerem maior eficiência no alívio da dor nas quatro primeiras semanas após a infiltração com corticosteróides, similaridade dos procedimentos ao redor da quarta semana e melhores resultados com a viscossuplementação após a oitava semana. Este inicio de ação mais tardio, associado a relatos de sinovite reacional após a viscossuplementação podem desencorajar médicos e pacientes ao uso desta modalidade de tratamento. No presente estudo foram avaliados 104 pacientes em tratamento para osteoartrite do joelho no grupo de doenças osteometabólicas do Instituto de Ortopedia do Hospital das Clínicas da FMUSP. Os pacientes foram randomizados em dois grupos. Um dos grupos foi denominado VS e recebeu uma única injeção intra-articular de 6ml de Hylan GF-20 (Synvisc One®-Genzyme) no joelho estudado. O segundo grupo foi denominado VS+T e recebeu uma injeção intra-articular de 6ml de Hylan GF-20 (Synvisc One®-Genzyme) mais 1ml (20mg) de Hexacetonido de Triancinolona (Triancil®-Apsen). Foram aplicados a escala visual analógica de dor (EVA) e os questionários de WOMAC e Lequesne uma semana antes da injeção e após uma, quatro, 12 e 24 semanas. Os dois grupos com 52 pacientes cada eram homogêneos. Na primeira semana, o WOMAC e a EVA apresentaram melhores resultados no Grupo VS+T (p < 0,01) em relação ao Grupo VS. Na quarta semana não houve diferença entre os grupos. Ambos apresentaram resultados similares nas semanas 12 e 24. Concluiu-se que a adição de hexacetonido de triancinolona melhorou os resultados clínicos da viscossuplementação no curto prazo, sem interferir nos resultados a longo prazo ou na incidência de efeitos adversos / The present study aims to assess if the initial results of viscosupplementation can be improved by the addition of corticosteroid. Intraarticular injections have been used for many years to treat arthritis and other painful articular disorders, mainly using long-lasting crystalline corticosteroid suspensions. Viscosupplementation is a relatively new intervention that is now widely used and recommended for the treatment of knee osteoarthritis. It is comprised of the injection of exogenous hyaluronic acid in diarthrodial joints, in order to restore the rheological properties of synovial fluid and also to promote osteoarthritis disease-modifying effects. Several placebo-controlled studies reported that clinical improvement began only within two to five weeks after viscosupplementation. When comparing viscosupplementation versus intraarticular injection of corticosteroid, recent data suggest that from baseline to week four, intraarticular steroid were more effective for pain relief. By the fourth week, however, both provided similar relief, but beyond the eighth week, hyaluronic acid provided greater pain reduction. The mechanism of action of hyaluronic acid, with delayed onset of pain/functional improvement, combined with reports of reactional sinovitis may discourage physicians and patients regarding this treatment modality. The present study evaluated 104 patients receiving usual care for knee osteoarthritis at the University of São Paulo Medical Center. Patients were randomized to receive either a single intra-articular injection of 6ml of Hylan GF-20 (Synvisc One®-Genzyme) (Group VS) or a single intra-articular injection of 6ml of Hylan GF-20 (Synvisc One®-Genzyme) plus 1ml (20mg) of Triamcinolone Hexacetonide (Triancil®-Apsen) (Group VS+T). VAS, WOMAC and Lequesne questionnaires were applied one week prior the injection, and after one, four, 12 and 24 weeks. The two groups with 52 patients each were homogeneous. At week one, WOMAC and VAS showed better results for Group VS+T compared to Group VS (p < 0,05). At week four the scores did not show statistically significant differences. The groups showed similar results at weeks 12 and 24. In conclusion, the addition of triamcinolone improved first-week symptom and functional scores of viscosupplementation, but not beyond. It did not seem to alter the likelihood of adverse effects

Web applications using the Google Web Toolkit / Webanwendungen unter Verwendung des Google Web Toolkits

von Wenckstern, Michael 04 June 2013 (has links) (PDF)
This diploma thesis describes how to create or convert traditional Java programs to desktop-like rich internet applications with the Google Web Toolkit. The Google Web Toolkit is an open source development environment, which translates Java code to browser and device independent HTML and JavaScript. Most of the GWT framework parts, including the Java to JavaScript compiler as well as important security issues of websites will be introduced. The famous Agricola board game will be implemented in the Model-View-Presenter pattern to show that complex user interfaces can be created with the Google Web Toolkit. The Google Web Toolkit framework will be compared with the JavaServer Faces one to find out which toolkit is the right one for the next web project. / Diese Diplomarbeit beschreibt die Erzeugung desktopähnlicher Anwendungen mit dem Google Web Toolkit und die Umwandlung klassischer Java-Programme in diese. Das Google Web Toolkit ist eine Open-Source-Entwicklungsumgebung, die Java-Code in browserunabhängiges als auch in geräteübergreifendes HTML und JavaScript übersetzt. Vorgestellt wird der Großteil des GWT Frameworks inklusive des Java zu JavaScript-Compilers sowie wichtige Sicherheitsaspekte von Internetseiten. Um zu zeigen, dass auch komplizierte graphische Oberflächen mit dem Google Web Toolkit erzeugt werden können, wird das bekannte Brettspiel Agricola mittels Model-View-Presenter Designmuster implementiert. Zur Ermittlung der richtigen Technologie für das nächste Webprojekt findet ein Vergleich zwischen dem Google Web Toolkit und JavaServer Faces statt.
