Test Bench for Experimental Analysis of Conductive Composite Materials for Aerospace Applications.
Pham, N. N. ; Leuchter, J. ; Václavík, J.
The paper presents the materials used in aerospace industry and introduces an automated test bench for investigating these materials’ electrical properties. The test bench is also designed to investigate aviation electronic components, especially regarding electromagnetic compatibility (EMC). The test bench contains various measuring instruments which are connected to a computer (workstation). The designed program on the computer supervises identifying connected instruments and creating communication channels to those instruments. This program also controls those instruments to conduct required measurement or testing and obtain the measuring results. Instrument control is realized by using Standard Command for Programable Instrument (SCPI) commands. The program is designed in MATLAB development environment and add-on application MATLAB App Designer with toolboxes Instrument Control Toolbox and Signal Processing Toolbox.

Debugger for Windows
Václavík, Jiří ; Yaghob, Jakub (advisor) ; Bednárek, David (referee)
This work deals with analysis of available debugging means of the operating system Microsoft Windows XP on the IA-32 platform and ensuing implementation of an application debugger. The resulting implementation (the project RazeDebugger) supports multithreaded debugging, SIMD instructions, and viewing of accessible debugging information from source code. The work also includes comparison of the project RazeDebugger and other existing debuggers. The comparison aims at these aspects of debuggers: available functions, user friendliness, CPU usage, performance, stability, and also reaction to special behavior of the debuggee.

CSG modeling for polygonal objects
Václavík, Jiří ; Křivánek, Jaroslav (advisor) ; Beneš, Jan (referee)
This work deals with an efficient and robust technique of performing Boolean operations on polygonal models. Full robustness is achieved within an internal representation based on planes and BSP (binary space partitioning) trees, in which operations can be carried out exactly in mere fixed precision arithmetic. Necessary conversions from the usual representation to the inner one and back, including their consequences are analyzed in detail. The performance of the method is optimized by a localization scheme in the form of an adaptive octree. The resulting implementation RazeCSG is experimentally compared with implementations used in practice Carve and Maya, which are not fully robust. For large models, RazeCSG shows only twice lower performance in the worst case than Carve, and is at least 130 times faster than Maya.

Development of a Small Family Business
Vaclavik, Jakub ; Bočková, Nina (referee) ; Koráb, Vojtěch (advisor)
The aim of this bachelor thesis is to describe a development of a small family business, a brewery located in Sušany, which will distribute beer to surrounding villages and towns in districts of Poltár, Rimavská Sobota and Lučenec. The thesis is divided into three parts. First, theoretical part, includes definition of terms that relate to business. Present condition, surroundings of an enterprise and its opportunities are described in second, analytical part. Finally, we put forward a detailed proposition of how the brewery should work, expand and make profit.

Methodology of camera spectral response measurement
Melich, Radek ; Václavík, Jan ; Žídek, Karel
Spectral response of the camera will be measured using monochromator in conjunction with an integration sphere. Camera without objective will be placed in one port of the integrating sphere and light beam from monochromator will be fed into perpendicular port. Sensor of the camera sensor will be therefore uniformly illuminated by diffused light from monochromator. Proposed FWHM of the monochromator is 15 nm as a trade-off between light intensity provided by monochromator and deformation of spectral characteristic (Picture XY). Diameter of the integrating sphere has to be larger than 100 mm to ensure uniform illumination over sensor area.
