This thesis presents the design, creation, and testing of a web-based tool for generating interactive web-based problem set assignments. In prior research (Stetka, 2001) it was shown that students enjoyed interactive problems. In this research, multiple programming languages were used to provide a web-based, fully interactive, problem solving environment for the students.Sample problem sets were written by the author and a few chemical engineering students. These web pages were then used as a basis to test the effectiveness of the web-based interactive problem sets for two engineering courses. Initial findings are presented illustrating the students results along with results of student feedback surveys. Additionally, an analysis of the feedback from the two levels of users, students and instructors are reported and some suggestions for further development are given.

Almost all commercially available wireless access devices are special embedded systems with proprietary software that do not allow any modifications. Modifications to these systems are only possible by firmware upgrades released by manufacturers. However, release times of these firmware upgrades are unpredictable, and they are usually for bug-fix purposes rather than being feature and capability improvements. Thus, these devices fail to provide the needed flexibility. Ability to provide timely custom solution that is well integrated into existing network infrastructure is the key factor for a successful wireless access service implementation. In this thesis work, the open source software called AWLP is designed, coded, tested, and released to public as a viable alternative for creating custom wireless access device.

The diploma thesis deals with design and implementation of cooperative work on documents in the application TEXonWeb. The diploma theses includes the analysis of competitive solutions and key technologies for implementation. The cooperative work on documents is a functionality which allows users to cooperate simply on one document in real-time. Text of the thesis describes the process of implementation using the technology which is described in the initial analysis. The diploma theses also includes some ideas for next possible development.

Esta dissertação investiga o processo de conversão automática de textos estruturados para hiperdocumentos. Analisa vantagens e desvantagens da utilização de um processo automático. Faz um levantamento detalhado das etapas envolvidas nesta conversão. Como resultado da pesquisa propõe um processo de conversão baseado em definições formais da estrutura dos documentos e das citações. O domínio de aplicação do processo de conversão é o conjunto de normas estatutárias jurídicas brasileiras. Outro resultado deste trabalho é a ferramenta WebifyLaw que implementa o processo de conversão automática para o conjunto das normas estatutárias jurídicas brasileiras. Os resultados da aplicação da WebifyLaw na Constituição Federal, no Código Civil e no Código de Processo Civil e em outras 42 normas são apresentados e discutidos. / This work centered in the research of the automatic conversion of structured texts into hyperdocuments. It presents an analysis concerning the advantages and disadvantages of such automatic process. It also details the steps involved in this conversion. As one of the results it proposes an automatic conversion process, which is based on document structure and citations´ formal definitions. The application domain is set as Brazilian statutory norms. Another contribution from this work is a tool called WebifyLaw, which implements the automatic conversion process for the chosen domain. The tool was applied to the Brazilian Constitution, the Civil Code among other 42 norms. The results obtained in using this application are also presented and discussed.

This master thesis deals with implementing triple-play services and providing it’s quality of services in heterogenous comunnication networks. The aim of thesis is to apply the- oretical methods in real case and existing network infrastructure. Practical part aims to create technical solution to prioritize network traffic based on classification of required services. The technical solution is created with conditions of being possible to add more functions and to provide scalability.

This master thesis deals with wireless sensor network with protocol IPv6. In the begining there are explained the priciples of communication in wireless sensor network, and based on this teories are configured a wireles network with predefined development kit. Furthermore, by using geographic coordinates, positions of the nodes are displayed on a website, what is a part of this thesis. On this website are also presented the measured values from sensors. For saving all informations and measured values about each nodes was used remote MySQL server. Communication between this server and 6LoWPAN network provide Perl script which is runs at periodical intervals. With this method automatization of the whole system are ensured.
