This Diploma thesis aims to explain the data coding using turbo codes. These codes belong to the group of error correction codes. We can reach the high efficiency using these codes. The first part describes process of encoding and decoding. There are describes parts of encoder and decoder. Principle of encoding and decoding demonstrate a simple example. The end of this part contains description of two most frequently used decoding algorithms (SOVA and MAP). The second part contains description of computer program that was made for using as teaching aid. This program was created in Matlab GUI. This program enables to browse error correction process step by step. This program contains graphic interface with many options and display results. In the third part is described program created in Matlab Simulink that was implemented into the TMS320C6713 kit and there is description of measuring procedure. For verification of efficiency of turbo codes was measured any parameters. Some of these parameters are: number of decoding iterations, generating polynoms and using of puncturing. The last part contains measured value and result evaluation.

Master’s thesis proposes a new algorithm which enables efficient conversion of graphical representation of warehouse into graph theory representation and consequently accelerates estimation for route costs. The proposed algorithm computes route distances between any places in warehouse based on Breadth first search, image processing „skeletonization“ and Dijkstra algorithm. Using the proposed algorithm it is possible to search routes in a warehouse effectively and fast using precomputed routing table. Searching time is less then milisecond using routing table and even size of warehouse doesn’t affect it significantly instead of using Dijkstra algorithm.

The aim of the thesis was to ensure simple and clear operation while providing users the ability to monitor and analyze the current historical data from sensors in the smart home. Beyond the task I have extended the work on the Windows Phone platform. Designed user interface based on the requirements for intelligent home control in the project IoT (Internet of Things), which are written in this work. Tests were conducted using the available auto-mated testing and continuous testing at alpha and beta. Finally, the quality of the interface and user friendliness assessed using questionnaires.

At the beginning of this work the physiological nature of electromyographic signal is described. Design of miniature, portable EMG amplifier for surface measurement is presented. Creation of program for data visualization is described, followed by description of practical EMG amplifier realization.

Hlavním bodem je vlastní návrh a implementace nástroje na tvorbu multiplatformních hardwarově akcelerovaných grafických uživatelských rozhraní. Srovnává vlastní koncept s existujícími řešeními, a uvádí ho do praxe na projektu s externí firmou.

Maintaining quality in software is a difficult task for several reasons, such as, company growth, time-to-market demands, code complexity and more. GUI testing tools and Continuous Integration (CI) are common practice today to tackle some of the issues with maintaining software quality. However, these techniques bring a set of challenges. Visual Regression Testing (VRT) is a special kind of GUI testing technique focused upon image-based assertions. This study presents an implementation and investigation of the benefits and drawbacks of introducing VRT for a CI environment in an industrial context. Additionally, the thesis investigates factors that need to be considered upon this transition. The results show that benefits are associated with this approach, such as, quicker feedback times and an increase in testing frequency. However, drawbacks and implications were also identified, such as, test maintenance and organizational concerns, indicating careful consideration needs to be taken by an organization before proceeding with an implementation.

Datenbanken finden in mehr und mehr Bereichen einen Einsatz. Angestrebter Datenaustausch zur Vernetzung von Informationen und Gewinnung zusätzlicher Kenntnisse ist wegen der Heterogenität von den Datenbanken problembehaftet. Schema- Matching beinhaltet durch das Erzeugen von Korrespondenzen zwischen Schemata eine Lösungsmöglichkeit für zumindestens einen Teil dieser Probleme. Viele Ansätze wurden schon für das Schema-Matching entwickelt und werden in dieser Arbeit dargestellt. Es werden Strategien zur Wiederverwendung näher erläutert und Erweiterungen für die Mapping-Wiederverwendung vorgestellt. Die neuen Strategien, die in dieser Diplomarbeit entstehen, wurden in dem Schema-Matching-Prototyp COMA++ integriert und zusammen mit anderen Strategien evaluiert.

Im Rahmen des ¨European Fireball Networks¨ fallen jährlich etwa 100 Aufnahmen von hellen Feuerkugeln an. Zur Zeit kann jedoch nur ein Bruchteil des Datenmaterials umfassend ausgewertet werden, da die manuelle Vermessung der Aufnahmen an einem Meßtisch sehr aufwendig ist. Im Rahmen der Diplomarbeit wurde das Programm ¨Fireball¨ zur automatischen Vermessung von Feuerkugelfotografien entwickelt. Die Arbeit beginnt mit einer umfassenden Einführung in die Thematik der Meteorbeobachtung. Die Algorithmen der digitalen Bildverarbeitung bilden den Schwerpunkt der Diplomarbeit. Sie umfassen * die Digitalisierung der Negative * die automatische Segmentierung, Identifizierung und Vermessung von Sternspuren (ohne Zusatzinformationen) * die manuelle Vermessung der Meteorspur im digitalisierten Bild Im Anschluß wird die Schnittstelle zu weiterführender Software diskutiert. Der zweite Schwerpunkt ist der Entwurf einer komfortablen grafischen Benutzerschnittstelle. Deren Implementation erfolgt in C bei Verwendung des Motif-Toolkits unter UNIX. Die Arbeit endet mit dem Ausblick auf zukünftige Entwicklungen sowie einem Glossar und dem Literaturverzeichnis.

Einführung in die Script- und eingebettete Sprache Tcl/Tk. Einsatzmöglichkeiten als Scriptsprache, bei Internetanwendungen und zur Erstellung graphischer Programmoberflächen.

The software plays an important role in the current era of automotive development and the robust functionality of a software can only be achieved by following proper development process. The requirement engineering and the management of requirements are one of the key point in the software development. The requirements help the software developer to validate and verify the designed software. The Knorr-Bremse is one of the leading company in the automotive and locomotive industry which expertise in the area of braking system. The software department has been searching for a new approach in the area of requirement tracing and to evaluate the progress and performance of the complete system. They planned to design a new tool which should be able to trace the requirement and signals which means it should detect the new variation in the project automatically and update the software modules and test cases. Another mandatory functionality of tool is the measurement of progress and performance of complete system/project. The evaluation includes the quality of work of the software developer as well as the recording of milestones which has been achieved. A project has been planned for this master thesis is to develop a tool using various programming languages such as C-sharp, ASCET, ESRA Launcher, Graph-viz and XML. The purpose of this tool is to solve the above stated scientific challenge. The first phase is to design a tool which extracts the specific project data such as requirements and signals from 620 Requirement Specification files and then this data would search for the multi-level trace points in software and test modules based data. Upon successful search, the tool generates graphical representation of trace points for selected level of architecture. The second phase is to enhance the tool for measure the progress and performance of project selected by user. This task has been performed by developing an KPI. The GUI has been developed which represents the previous and current progress of project using famous graphical methods such as histogram, stag bar, bubble chart etc.
