Web Application for Visualization of Values in Geographical Coordinates
Kašpar, Petr ; Bartík, Vladimír (referee) ; Hynek, Jiří (advisor)
Data visualization in maps is a technique of data presentation, which displays spatially-bound variables. The objective of this thesis is to create a web application capable of creating visualizations of data in geographic coordinates, enabling user to analyze observed phenomenon in many different levels of view, ranging from the general overview of patterns to the analysis of fine details. The Geovisto library is capable of visualization of generic data and their connections but these visualizations are limited to the territories of states and do not work with exact geographic coordinates. This is inconvenient for some kinds of data analysis and makes visualizations of data sets that work with exact coordinates impossible. I focused on extending this library by map layers capable of visualizing data in exact geographic coordinates.

Design of 3D Vivaldi antenna array for radar applications
Kašpar, Petr ; Pitra,, Kamil (referee) ; Puskely, Jan (advisor)
This master thesis deals with a design of Vivaldi antenna due to its broadband properties suitable for radar applications. The folding of single Vivaldi antenna element into 2D antenna array we achieved required radiation properties. Appropriate design of feeding structure realized by SIW technology we obtained suppression of side lobes and deflection of the main lobe. The work also includes design of 3D Vivaldi antenna array. Modeling, simulation and optimization of antenna array were performed in CST Microwave Studio.

Communication Adaptor for Data Acquisition System Hardware and Software Design
Kašpar, Petr ; Frýza, Tomáš (referee) ; Jakubová, Ivana (advisor)
The aim of this bachelor thesis is to create adaptor with microcontroller for data acgusition system. Function of the device is to receive serial asynchronous string of ASCII characters which was send from ultrasonic thickness gauge. Baud rate of transmittion is 2400Bd. Transmittion is realized according to RS-232 standard. Part of the string contains numeric information about value which was measured by thickness gauge. This numeric information is in microcontroller multiplied with corrective constant and decimal point in result is placed to right position. Corrective constant is stored in EEPROM memory. After that adaptor transsmits data to superior system in format of serial asynchronous string of ASCII with baud rate 9600Bd. Thesis describes service code for microcontroller in Assembler language and hardware construction of device.

Development, implementation and testing of algorithms for measurements of electromagnetic signals detected onboard a stratospheric balloon above thunderstorms
Amrich, Samuel ; Santolík, Ondřej (advisor) ; Kašpar, Petr (referee)
In this work, we focus on the application of machine learning techniques to study radio recordings of lightning discharges. Our goal was to develop an algorithm that could autonomously detect and classify different types of lightning discharges, as well as their groups or developmental stages. To this end, we tested various methods of classical ma- chine learning as well as deep neural networks. All of these models were trained itera- tively on archival data. The results of our work show that it is possible to effectively use machine learning methods for detection and classification purposes, with the aim of deploying them on board the STRATELEC stratospheric balloon project. In the future, our findings should be deployed on board the stratospheric balloon and could be used to improve understanding of the processes involved in creating lightning discharges in a thundercloud. 1

Legal regime of protected areas and protective zones to protect water
Kašpar, Petr ; Franková, Martina (advisor) ; Snopková, Tereza (referee)
This diploma thesis deals with the legal regime of protected areas and protective zones used to protect water. The diploma thesis is composed of four chapters. Chapter one defines basic terms, a protected area and protective zone, in general. This chapter also contains a comparison of both institutes and their application in environmental protection. The second chapter deals with the sources of relevant legislation protected areas and protective zones to protect water. Chapters three and four are central of the thesis as they contain an interpretation of legislation of each types of protected areas and protective zones to protect water. For individual institutes is analyzed their concept, function, form and method of their determination and especially their special legal regime based namely on bans and restrictions regarding certain activities in the given area. Attention is also paid to various limitations of property rights to real estate in the protected areas and protective zones and to possible compensations for such limitations.

Macroscopic gravity
Kašpar, Petr ; Svítek, Otakar (advisor) ; Žofka, Martin (referee)
Due to the nonlinearity of the Einstein equations it is possible to obtain modified equations of the general relativity (with application in cosmology) just by averaging. One of the first covariant approaches to this problem is the theory of Macroscopic Gravity. Next proposed possibility is to first characterize spacetime by the Cartan scalars and then to proceed averaging procedure.

Fast measurements of magnetic signals generated by natural lightning discharges
Kolínská, Andrea ; Santolík, Ondřej (advisor) ; Kašpar, Petr (referee)
The main focus of this thesis is, first of all, electromagnetic radiation generated by natural lightning discharges. More specifically, the thesis is oriented towards analysis of the return strokes and preliminary breakdown processes. This thesis also summmarizes our current knowledge of lightning discharges, aiming more in detail at results of previous work concerning return strokes and their initiation. The analysis of measurements of the SLAVIA sensors provided us with detailed information on the character of 92 return strokes and 40 preliminary breakdown pulses which were recorded between October 2013 and June 2014. In 63 % of lightning flashes the amplitude of the largest preliminary breakdown pulse was lower than the amplitude of the corresponding return stroke, although the ratio of these amplitudes was prone to seasonal changes. In summer the sensors detected a higher percentage of lightning flashes for which the amplitude of the largest preliminary breakdown pulse was higher than the amplitude of the return stroke. The average time interval between the largest preliminary breakdown pulse and the first return stroke was approximately 10 ms. This measurement was also prone to seasonal changes, with the average time interval raising in summer. Moreover, the return strokes varied as to the shape of the...
