Design of a part of the Information System Used to Analyze and Manage Customers of a Consulting Company with the Help of Business Intelligence.
Dvořák, Vojtěch ; Novák, Lukáš (referee) ; Neuwirth, Bernard (advisor)
The aim of the bachelor thesis is the design of a part of the information system that uses business intelligence to analyze, divide and manage customers of a company providing financial advisory services. The first part of the thesis will be to perform an analysis of the current state and a survey of the customer handling system. The purpose of the proposed solution will be to form customer analysis that can be further used for better prediction of further use of services by customers, thus better targeting of marketing and more effective system of work of consultants of the firm thanks to the application of business intelligence. The work will also include an evaluation of the expected economic benefits for the company.

Incremental Parsing for YARA Language
Dvořák, Vojtěch ; Kolář, Dušan (referee) ; Regéciová, Dominika (advisor)
The main goal of this bachelor thesis is to design and implement a program library that enables incremental static analysis of the YARA language. One of the main purposes of this new library is to integrate with the open-source Yara Language Server project developed by Avast. Compared to the existing solution, which uses a non-incremental approach to analysis, the machine time requirements should be reduced. In addition to information about the software solution, this thesis also includes a summary of the theory focusing on static analysis and its incremental variant, essential information about the YARA tool, and an introduction to the existing solution, the Yaramod-v3 library. The thesis also contains a comparison of the new library with the current solution, in which the achieved results are presented. The experiments performed showed that the new library is able to perform incremental analysis of a modified rule set approximately 20× – 2000× faster depending on the particular set.

Verification of SoC with ARM Cortex M0/M0+ processor
Gumenyuk, Artem ; Dvořák, Vojtěch (referee) ; Fujcik, Lukáš (advisor)
The work deals with the theory of operation of the ARM Cortex-M0/M0+ processor and analyzes the design possibilities of verification components. It describes the design and implementation of verification components for monitoring the correct operation of the system with an ARM-CortexM0/M0+ processor and displaying important data throughout the simulation run. It then demonstrates component outputs on an assembled reference design.

Implementation of remote terminal on Milbus
Čechura, Petr ; Fujcik, Lukáš (referee) ; Dvořák, Vojtěch (advisor)
This bachelor thesis deals with the Milbus communication bus and the design of a remote terminal into a gate-level FPGA circuit using VHDL. The first chapter is dedicated to the MIL-STD-1553B standard - it discusses the functionalities that the bus contains, revealing the communication rules and limitations. The second chapter introduces the reader to the ECSS-E-ST-50-13C standard, describing the use of the bus in space technology, or in general, robust, complex systems where effective communication control is required. In the last (practical) part, the architecture of the remote terminal is developed based on the knowledge gained in the previous chapters in order to provide the basic functions (receiving and sending data). Based on the specified requirements, the architecture is verified and finally synthesized into a Spartan3 FPGA, model XC3S50.

Picture generation using path tracing
Áč, Ondřej ; Dvořák, Vojtěch (referee) ; Pavlík, Michal (advisor)
This thesis deals with the problematics of computer-generated imagery using path tracing. The goal of this work is to create interactive computer program, which allows editing and rendering of photorealistic images of various scenes in real time. The work presents the concept of rendering equation, along with its known solutions, in the theoretical part of the work. Thesis describes in detail the solution using path tracing, based on the Monte Carlo integration technique, along with the benefits, it provides compared to the other techniques. Several hardware and software optimizations are then presented. Practical part of the work focuses on analysis of C++ source code and compiled assembly code whilst using hardware specific SIMD optimizations. Mandatory part of work is also the demonstration of program’s functionality, along with the measurements of achieved performance gains using manual optimizations.

The yield parameters and weed infestation of proso millet in the
DVOŘÁK, Vojtěch
Systems of intercropping represent one of the ways of biotic intensification in plant production. The aim of the work was to determine the effect of false flax (Camelina sativa) as the intercropped with millet (Panicium millet) on the occurrence of weeds in the stand and to determine the optimal density of false flax from the point of view of achieving a high yield of millet grain. The fallow was sown in the millet stand at densities of 100, 150, 200 and 250 plants/m2 in two sowing dates, and the weeding of the stand, the beginning of millet flowering, the height of the plants, the yield of fresh biomass and the yield of millet grain were monitored. On the basis of the obta-ined results, false flax can be recommended for intercroping with common millet.

Colorant properties and stability of Reynoutria pigments
DVOŘÁK, Vojtěch
This bachelor thesis is focused on invasive species of the genus Reynoutria, specifically on obtaining color extracts from their rhoots and subsequent evaluation of their color properties under various environmental conditions in laboratory conditions. The color properties of extract L, a, b, Cab, h and Eab were evaluated using a colorimeter. The extracts were obtained with 96°C warm water, cold water and 100% ethanol from dried and fresh material. The dye content in rhizomes and stems of Reynoutria japonica and Reynoutria sachalinesis was evaluated based on the total The roots of Reynoutria japonica and Reynoutria sachalinesis can be used as a source of yellow to red-violet dye. For the preparation of the extract, dried roots can be recommended at an extraction ratio of 3 g per 1 liter of water and extraction at 95 ° C for 1 hour. The information obtained can potentially be used in the application of dyes in industry or, after verification of health safety, also in the food industry.

Data protection in SRAM type memory with error correction code
Záhora, Jakub ; Fujcik, Lukáš (referee) ; Dvořák, Vojtěch (advisor)
The thesis contains basic concepts necessary for understanding the theory of coding. It then explains the parameters that will be monitored for the described codes. Based on the criteria, it selects the BCH code and the Extended Hamming Code, as appropriate, and further compares their properties to select a more efficient code from this pair. As a result of the comparison, it selects the Extended Hamming Code as more suitable for the subsequent design of the program. The code design procedures, tests that verify the functionality of the code, and the resources used for the Spartan-3 circuit to implement the code for the Spartan-3 circuit are then shown.
