This thesis reports the analysis of the rectangular shaped defected ground structure (RS-DGS) and the application of the structure on some microwave devices. DGS is analyzed in terms of its superior properties, which enables the designers to easily realize many kind of microwave devices which are impossible to achieve with the standard applications. Within the scope of this thesis, the focus is on the rectangular shaped DGS and its characteristic properties. The basic slow wave and high impedance characteristics are utilized in the design of some microwave devices. The design is carried on at the two different frequency bands: X-band and Ka band, centering at 10 GHz and 35 GHz, respectively. Finally, using the high impedance property and the coupling between the defects, a wide band 1 : 4 beam forming network is designed and implemented at 10 GHz.

Também conhecido como Desenvolvimento Global de Software (DGS), esse modelo de desenvolvimento é realizado por equipes em diferentes localizações geográficas. Entre os fatores que contribuem para esse aumento, está a necessidade de negócio das corporações, que buscam redução de custos, recursos qualificados e necessidade de uma presença global. Em outros casos, se deve ao surgimento de novos movimentos de desenvolvimento de software, como a comunidade de software livre, um exemplo bem sucedido de DDS. Apesar da necessidade ou mesmo da conveniência de desenvolver o software de forma distribuída, é extremamente difícil fazê-lo com sucesso. A separação física traz uma série de problemas e desafios interessantes que recém estão começando a ser compreendidas: questões estratégicas, questões culturais, comunicação inadequada, gestão do conhecimento, alocação de tarefas, confiança, questões técnicas, entre outros. Desde que surgiu, o DDS mudou grande parte da tradição do desenvolvimento de software e, para manter o seu mercado, as organizações não podem depender das mesmas competências e tecnologias de engenharia de software utilizadas no desenvolvimento interno. Nesse sentido, o presente trabalho tem por objetivo auxiliar na redução dos problemas e dificuldades trazidos por esse modelo de desenvolvimento, através da implementação de um ambiente de desenvolvimento cujas ferramentas foram definidas com base em estudos e trabalhos relacionados ao tema. / The Distributed Software Development (DSD) is a development model that has been intensified in recent years. Also known as Global Software Development (GSD), this development model is done by teams in different geographical locations. Among the factors that have contributed to this increase, there is the corporations business need of seeking ways to reduce costs, seeking skilled resources and having a global presence. In other cases, it is due to the emergence of new movements in software development, such as the free software community, a successful example of DSD. Despite the need or even desirability of developing software in a distributed way, it is extremely difficult to do this successfully. Physical separation has a number of interesting problems and challenges that are just beginning to be understood: strategic issues, cultural issues, inadequate communication, knowledge management, task allocation, trust, technical issues, among others. DSD has changed much of the tradition of software development since it appeared. Organizations cannot rely on the same skills and software engineering technologies used internally to maintain this new market. In this way, this work aims to help to reduce the problems and difficulties brought by this type of development, through the implementation of a software development environment whose tools were defined based on studies related to the topic.

In our presentation we will show how technology enables us to improve the teaching and learning of linear functions at the middle school level. Through various classroom activities that involve technology such as dynamic geometry software, graphing calculators and Excel, students explore functions and discover basic facts about them on their own. Students then work with real life data and on real life problems to draw graphs and form linear models that correspond to given situations as well as draw inferences based on their models. Participants will receive complete classroom materials for the unit on linear functions.

Während die Verdolmetschung lautsprachlicher Theateraufführungen in die Gebärdensprache in vielen Ländern selbstverständlich und regelmäßig angeboten wird, handelt es sich in Deutschland dabei noch um Einzelerscheinungen. Eine Ausnahme stellt das Hans Otto Theater Potsdam dar, das seit 1996 regelmäßig gedolmetschte Aufführungen anbietet und dabei die Methode des Shadow Interpreting nutzt. Am Beispiel einer gedolmetschten Aufführung von „My Fair Lady“ am Hans Otto Theater werden in dieser Arbeit folgende Aspekte der gebärdensprachlichen Verdolmetschung von Theateraufführungen untersucht: Stückauswahl, Dolmetscheranzahl und Rollenverteilung, Auswahl und Einführung von Namensgebärden der Figuren, Positionierung der Dolmetscher, Rollendarstellung und Rollenwechsel, Übertragung der akustischen Ebene des Aufführungstextes (linguistische und paralinguistische Informationen, Musik, Geräusche), äußere Erscheinung der Dolmetscher, Beleuchtung der Dolmetscher und die Inkorporation der Dolmetscher in die Aufgabe.
