Modified Genetic Algorithms for Cellular Automata Design
Magdolen, Matej ; Vašíček, Zdeněk (referee) ; Bidlo, Michal (advisor)
This bachelor’s thesis aims to examine possibilities of designing a transition function enabling a cellular automaton to solve a given problem using a genetic algorithm. It contains an introduction to cellular automata, evolution algorithms and conditionally matching rules, a method of descripting a transition function suitable for evolutionary development. A set of experiments is conducted using the standard version of genetic algorithms to determine its optimal configuration. Additionally, modifications of this standard algorithm are proposed, effect of which on the algorithm’s performance is then evaluated by further experiments.

Wireless Communication in Fire Sport
Pelka, Tomáš ; Mrázek, Vojtěch (referee) ; Vašíček, Zdeněk (advisor)
This work describes the design of wireless timer for fire sport disciplines. Its aim is to replace long wires with wireless communication while preserving equal or better reliability. Important part is the need for clock synchronization between wireless modules. Related topic is selection of suitable synchronization algorithm and communication protocol. The proposed system was realized in form of prototype using Texas Instruments's development platform LaunchPad EXP 430 FR4133 and wireless modules with Texas Instruments's chip CC1101. Parameters of designed system (especially the accuracy of time synchronization and measurement) were verified in laboratory.

Arithmetic Circuit Generator
Bolješik, Michal ; Mrázek, Vojtěch (referee) ; Vašíček, Zdeněk (advisor)
The goal of this thesis is to design and implement a tool that would be able to generate a description of various types of arithmetic circuits, such as adders and multipliers, that are involved in more complex systems (filters, transformations, etc.). The first part of the thesis deals with analysis of different types of adders and multipliers on either theoretical or practical level. In the second part there is a description of the design and implementation of the tool created in Python language. On base of parameters, the tool is able to generate hierarchical or flattened description of various circuits in formats aimed for visualization, simulation and validation. In the end, the tool is used to compare different designs of adders and multipliers.

Application Development Framework for the ARM Platform
Buchta, Petr ; Sekanina, Lukáš (referee) ; Vašíček, Zdeněk (advisor)
This master's thesis focuses on designing and implementing a framework that would offer basic program resources for application development on hardware platform FITkit Minerva. First part of this work focuses on designing a data channel between PC and the kit for which the USB interface was used. Next part focuses on implementing a channel between an ARM based microcontroller and FPGA Xilinx Spartan-6. That led to creating a special system inside FPGA that allows adding new HW components that communicate with the microcontroller, which can be used for implementing HW acceleration techniques. Another outcome of this work is a debugging interface that allows to program and debug FPGA using development environment Xilinx ISE without a need of the original Xilinx JTAG adapter. This was achieved by using the XVC protocol that allows to create a custom JTAG adapter that in this case was implemented in the software of the microcontroller.

FITkit VGA Grabber
Lojda, Jakub ; Šimek, Václav (referee) ; Vašíček, Zdeněk (advisor)
This paper discusses the possibilities of realization of VGA grabber for FITkit. Text is focused on software and hardware implementation possibilities. The first part introduces the reader to the theory of the issue. Next, the paper proposes several options of VGA grabber implementation and brief evaluation of alternatives. The second part describes a chosen architecture of VGA grabber of the featured options and includes a brief summary of the findings of the processor LPC4370 from NXP and USB Video Class UVC, on which the resulting architecture is based. The conclusion includes a brief summary.

Evolutionary Design for Circuit Approximation
Dvořáček, Petr ; Vašíček, Zdeněk (referee) ; Sekanina, Lukáš (advisor)
In recent years, there has been a strong need for the design of integrated circuits showing low power consumption. It is possible to create intentionally approximate circuits which don't fully implement the specified logic behaviour, but exhibit improvements in term of area, delay and power consumption. These circuits can be used in many error resilient applications, especially in signal and image processing, computer graphics, computer vision and machine learning. This work describes an evolutionary approach to approximate design of arithmetic circuits and other more complex systems. This text presents a parallel calculation of a fitness function. The proposed method accelerated evaluation of 8-bit approximate multiplier 170 times in comparison with the common version. Evolved approximate circuits were used in different types of edge detectors.

Excursion quide
Kožušníková, Alena ; Konečný, Pavel ; Vašíček, Zdeněk
The paper describes the locality Vondruška quarry and quarry in Stará ves near Bílovec. We can find the clastic sediments of the Hradec-Kyjovice members in both localities. Finally, the excursion visits the Green Gas DPB, a.s. where the exhibition of cores from mine drills in Ostrava and Karviná members has been exposed.

Guide to geological excursion in surroundings of Ostrava
Vašíček, Zdeněk ; Martinec, Petr ; Kožušníková, Alena ; Konečný, Pavel
The paper describes the most interesting geological localities in Ostrava region. Landek is unique outcrop of Carboniferous sediments of Upper Silesian Basin (Namurian A). Zámek Conglomerate outcrop is an important locality of the Poruba Member occurring near Silesian-Ostrava Castle. Exploitation of Pleistocene glacial gravels will be visited in Lake Kališčák near Bohumín. Geological “men made” locality is Ema dump which consists of waste rocks of Ostrava Formation.
