Techniques for parallel processing in .NET Framework
Hajn, Pavel ; Morský, Ondřej (referee) ; Lattenberg, Ivo (advisor)
This bachelor thesis describes the design of program which uses the techniques of parallel programming. The thesis contents theoretical and practical part. The theoretical part is focused on explaining the basic concepts such as multi-threaded execution of applications on singlecore and multicore processor, topology of threads and methods of parallel programming with using classes ThreadPool and Task Parallel Library, which describes the methods Parallel.For, Parallel.ForEach, Parallel.Invoke and TASK. In the practical section individual functions and specific methods needed for proper functioning of the program are explained, which represent simple archive of web pages. The sites are periodically checked and addresses of this website’s are specified in the configuration file.

Fly over Rugged Planet
Pospíšil, Petr ; Chudý, Peter (referee) ; Jošth, Radovan (advisor)
This thesis deals with a 3D visualization of the Earth´s surface in real time. A significant part is dedicated to the buffering of the large amount of data (a height map and textures of Earth) and its effective reading from hard disk directly to the memory of a graphic card. Individual levels of detail of the Earth´s surface are made by GeoMipMapping. The algorithms "horizon" and "frustum culling" are used, which cut off the hidden parts of the planet. The application of the height data is based on a custom algorithm calculating the data directly in the graphic card, in assistance with its vertex and geometry shaders.

Hardware Acceleration of Longest Prefix Match
Kekely, Lukáš ; Tobola, Jiří (referee) ; Kořenek, Jan (advisor)
This bachelor's thesis describes design and implementation of hardware architecture for longest prefix match in order to achieve high throughput, which is required in today's high-speed computer networks. It is focused on IPv4 as-well-as IPv6 networks. Designed hardware architecture has throughput 75 Gbps on the shortest IPv4 and IPv6 packets. Performance of designed architecture is also compared with performance of chosen algorithms, which are used in nowadays commercial devices. These algorithms are: Tree Bitmap, Shape-Shifting Trie and Binary Search on Prefixes. All algorithms were implemented in C language using multi-threaded processing.

Applicability of GCD Technology to Antivirus Software
Švec, Michal ; Janoušek, Vladimír (referee) ; Kočí, Radek (advisor)
This master's thesis describes Grand Central Dispatch technology. It is technology for parallel computing and task processing. It also describes history and techniques of parallel computing. As an example stand simple HTTP server with 4 methods of request parallel processing. Server is connected to AVG antivirus software and check each request for viruses.

Production of threads with taps
Chludil, Petr ; Sliwková, Petra (referee) ; Píška, Miroslav (advisor)
This thesis deals with the study of production process of threads by screw-taps from the very description of the individual threads through all the available methods of the threads production, thread control function, up to the actual taps, materials, coatings and their distribution. In the experimental part the thesis deals with the question whether it is possible to find an alternative to the standard production of threads using cutting by taps. This alternative seems to be the use of forming taps. The experiment took place under constant cutting conditions and consisted of two parts, one of them was the production of threads into the pre-drilled through holes and the second one was the production of threads into the pre-drilled impassable holes. The result of the experiment was finding the course of the cutting moment depending on the time and the amount of wear of the examined kinds of taps when all the measured values had to be statistically processed and conclusions were then evaluated.

Autonomous generator of test scripts
Horký, Stanislav ; Šimek, Václav (referee) ; Kolouch, Jaromír (advisor)
The subject of this master thesis are state machines and their testing. To this purpose, an application is described, which is able to test these state machines autonomously. Application have two parts, first generator and editor of data is built and second part is testing procedure, which is able to test state machines in question and to give corresponding test report.

System for acquisition of data from car communication system
Pecha, Michal ; Kučera, Pavel (referee) ; Fiedler, Petr (advisor)
The thesis contains complete design of complex system for acquisition of data from bus of a vehicle. It resolves problems of connection of a new node to CAN bus of a vehicle, communication protocol NMEA 0183 of GPS receivers, logging of caught CAN frames into database system MySQL, and proposes algorithms of application for operation of the system. It includes also process of complete installation based on established concept and test results of the system in real situations.
