In this essay, I have investigated whether players of World of Warcraft change their language to suit the gender of the character they play. I have researched if there are gender differences that correspond to what is defined as male and female language in mixed-sex conversations. Chat-logs, collected during four participant observations, were used for making an analysis based primarily on research by Coates (1993) and Yale (2007). Seven features were selected for analysis: amount of participation, hedges, questions, directives and commands, taboo language, compliments and grammar. It was possible to discover gender differences, but these were not consistent in all areas of research. For example, female characters had a higher contribution than males, as well as a higher use of hedges and tag-questions among males, which contradicts previous research. The lack of consistency might be due to the fact that the participants do not specifically consider all areas as typically female or male, or their unawareness of these tendencies. We also need to consider disagreement in previous gender studies as well as folklinguistic belief. The explanation of the lack of consistent differences may be a more equal relationship between males and females in this context, or due to thepossibility that the participants, who are usually male, make use of their normal male language.

[pt] A evolução do design de automóveis possui características interessantes, sob o ponto de vista da relação estético-funcional estabelecida em cada época. No início, os projetos de veículos únicos priorizavam a funcionalidade em detrimento do bem-estar do usuário. Com o tempo, esta maneira de se projetar foi sendo modificada, passando por períodos que valorizaram estritamente o desempenho, a aerodinâmica e a forma para um modelo onde a relação humano-máquina é o centro principal de estudo. Com novos e diferentes modelos de veículos, estes passaram a apresentar variações no posicionamento e projeto de comandos e mostradores, principalmente na região do cluster de direção. Desta forma, o presente estudo objetivou demonstrar que esta variação do posicionamento e de projeto gera confusão e erros de julgamento por parte do usuário, podendo ocasionar graves acidentes e incidentes durante a realização da tarefa, principalmente àquele que não está acostumado com o sistema a ser utilizado. Para comprovar esta hipótese, foi elaborado um estudo que, primeiramente, buscou entender o desenvolvimento dos comandos e mostradores automotivos e o uso de normas e recomendações de projeto para traçar um panorama da disposição das informações no interior dos veículos. Para o desenvolvimento da pesquisa, determinou-se o enfoque na categoria popular. O estudo do surgimento desta categoria, do panorama atual e do perfil do consumidor, contribuiu para se tentar observar o modelo mental dos usuários em relação ao posicionamento dos instrumentos. Para isso foram aplicadas diferentes técnicas, tais como um estudo comparativo dos modelos; a aplicação de questionários com usuários motoristas; e a realização de um grupo focal. O levantamento de dados contemplou ainda a realização de testes em um simulador real de interior de veículo. Outrossim, foi possível observar constrangimentos causados pela variação do projeto e pelo posicionamento de um grupo de comandos/mostradores do cluster e sugerir recomendações para projetos futuros. / [en] The evolution of automobiles design has interesting characteristics, under the point of view of the aesthetic-functionary relation established at each time. In the beginning, the projects of unique vehicles prioritized the functionality in detriment of well-being of the user. As time passed by, this way of projecting were being modified, passing by periods that had strict valued the performance, the aerodynamics and the form for a model which the human being-machine relation is the main center of study. With new and different models of vehicles, these had started to present variations in the positioning and project of commands and counters, mainly in the region of cluster. In this way, the present study aimed to demonstrate that this variation of the positioning and project generates confusion and errors of judgment by the user, and can cause serious accidents and incidents during the accomplishment of the task, mainly to that user that is not familiar with the system to be used. To state this hypothesis, a study was elaborated that, first, searched to understand the automotive development of the commands and counters and the use of norms and recommendations of project to trace a panorama of the disposal of the information in the interior of the vehicles. For the development of the research, the approach in the

This master thesis discusses design and realization of a security device for vehicles. This device can determine its actual location, discover unauthorized trespass and send information about this to a distant master system too. This distant master system can show the exact position of the security device on a map. The hardware and software for this security device and the software for the master system are described in this paper.

Aim of this master´s project is to analyse localization possibilities in GSM and GPS wireless networks. Choise of proper module and design location device for both GPS and GSM networks.

There is one transmitting option chosen in the third part and there are also described applications of the transmitting part. The last part of this thesis is focused on the receiving part and its application.

This thesis describes designing of a wireless system which allows to transmit measured data of sensors made of smart concrete. Measured data are transmitted from measuring points to the collecting unit, which stores them, and pass them to the server which is connected in the Internet network. The design of the system is focused to achieve low power consumption of all used components to provide the longest possible operation time, when using primary lithium cell. The design should be also able to provide possibility of easy modification of the measuring points.

The main theme of this masters's thesis is to design and make a miniature universal tracking device. This device is primarily for tracking asset, pets or people. For detecting the position data is used GPS technology. Data transmission is carried out via the GSM network. The device is technically solved and realized with respect to miniature size, high battery life and with regard to resistance against water, dust and impact damage. It is selected unique design, suitable for hermeticaly closure of the entire facility. Due to hermetic closure there is any buttons, any connectors and the battery charging is wireless.

This thesis is about the monitoring of testing station downtimes at the DS/ETC (Diesel Systems / Engineering Testing Center) Bosh Diesel s.r.o. department in Jihlava. The goal of the monitoring is to get a record and an immediate warning for each machine downtime. The testing engineers are able to edit downtime reports and to create statistics and the Pareto analysis based on the reports. In the beginning of the thesis there are generally described the ETC department and the SCADA system. The monitoring system is designed and implemented based on the requirements of the ETC department. SMS messages sent via a GSM module what is connected directly to the server are used for immediate downtime warning. The test engineers have the graphic user interface what they can use to edit downtime reports. Statistics are generated individually based on the adjustable data filter. The department can focus primary on the finding out the reasons of the downtimes what leads to the biggest reduction of the test machine downtimes.
