Parallel signal processing with help of GPU
Václavík, Jiří ; Frýza, Tomáš (referee) ; Mego, Roman (advisor)
In the introduction, the bachelor thesis outlines the origins of modern graphic processors. The theoretical part of the text describes the minimum of required information from parallel programming model essential to program simple DSP algorithms. The next part elaborate on three common DSP algorithms, finite impulse response filter, naive implementation of discrete cosine transform type II, and fast Fourier transform. To demonstrate parallel capability of GPU, algorithm for JPEG compression was chosen as JPEG compression is favorable because it illustrates both advantages and disadvantages of parallel data processing on GPU, and compromises needed to be considered.

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.

Active Loudspeaker Crossover with DSP
Václavík, Jiří ; Fedra, Zbyněk (referee) ; Povalač, Aleš (advisor)
Semestral thesis is devoted to mapping and verification technologies for the project active loudspeaker crossover using DSP. Three way systém will use open baffle. Design of analog crossover is complex due to the need of compensating for acoustic short circuit and properties of laudspeakers.

Blood vessel segmentation and modeling in fundus images
Václavík, Jan ; Odstrčilík, Jan (referee) ; Kolář, Radim (advisor)
Studies of the vascular tree in the retina have applications not only in the medical field but also biometrics. The mathematical description of the retinal vasculature could help facilitate and improve the diagnosis of certain diseases, their automatic localization or to accelerate the identification and verification of individuals. The aim is to design and develop an algorithm that will automatically approximate major retinal vessels by parabolic, linear and kvartic functions. The main part of this thesis is therefore devoted to this issue, including vascular segmentation using Gabor filters, morphological erosion, thresholding, skeletonization and the resulting optimization of the approximation model. The quality of the produced algorithm is discussed in the summary.

Image Interpolation
Václavík, Jan ; Odstrčilík, Jan (referee) ; Kolář, Radim (advisor)
This bachelor’s thesis deals with the comparison of different interpolation methods. And their use on different grey scaled 2D images. The main part is dealing with linear, quadratic and cubic method and their qualitative evaluation for multiple resizing of image resolution. The analysis is resolved in computing system Matlab.

Marketing strategy proposal of a newly established brewery
Vaclavik, Jakub ; Mráček, Pavel (referee) ; Chlebovský, Vít (advisor)
The diploma thesis focuses on marketing strategy. Its main goal is to propose a suitable marketing strategy for the emerging gypsy brewery, which will respect the internal and external environment of the brewery, and at the same time, contribute to the fulfillment of the goals and vision of the brewery. The thesis is divided into three main parts. The first part contains the theoretical framework in the field of marketing. The second part is the analysis of the current state, in which the macro-environment and the micro-environment of the brewery are analyzed. Within this part, research focused on customer behavior is also done. The third and last part is solution proposals. In this part, the marketing strategy is proposed, and thus the fulfillment of the main goal of the diploma thesis is attained.

Program Instrumentation Enabling Coverage Measurement
Václavík, Jan ; Peringer, Petr (referee) ; Smrčka, Aleš (advisor)
This thesis deals with the design and the implementation of the Ginstrum tool for compile time instrumentation of C programs. The tool is implemented as a GCC Plugin and instruments places in program that access memory, write to memory or call functions. The tool also provides compile information that can be used for the code coverage measurement during testing and dynamic analysis.
