FPGA programmer
Sedlář, Jan ; Pristach, Marián (referee) ; Bohrn, Marek (advisor)
The work deals with the analysis of the realization of FPGA programmers. Its aim is to create a functional programmer. The proposal aims to minimize the components, their cost and area. The programmer should support chips from manufacturers Altera, Lattice and Xilinx. The programmer should enable support functions such as data transfer, virtual switches and the programming button.

System for measurement and control of pressure in vacuum apparatus
Sedlar, Jan ; Jurik, Karel
This paper summarizes the development and implementationof a device designed for controlling and operatinga vacuum gas chamber. Multiple vacuum gauges, a gas pump anda valve can be connected to the device. Communication betweenthe user and the system occurs via a large touch screen withan organized interface. The article describes the current state ofdevelopment and outlines future improvement possibilities andpotential applications.

System for measurement and control of pressure in vacuum apparatus
Sedlář, Jan ; Steinbauer, Miloslav (referee) ; Juřík, Karel (advisor)
The aim of the bachelor's thesis is to create a system for measurement and control of gas pressure with available vacuum components in vacuum apparatus. After conducting research in the introductory sections of the thesis to better understand the issue and determine suitable problem-solving approaches, the goal of the thesis was implemented based on the theoretical design. The chapters of the thesis discuss the selection of appropriate components and their integration into the functional unit. Both hardware and software solutions implemented in the thesis are described. The automated pressure control in the apparatus is built upon multiple supporting resources of hardware and software nature, which combined create an automatically designed controller that enables easy achievement of the desired operating point for further research in the vacuum apparatus.

The importance of income on subjective well-being
Sedlář, Jan ; Baxa, Jaromír (advisor) ; Skuhrovec, Jiří (referee)
1 Abstract My Bachelor thesis deals in a comprehensive way with the discussion unleashed by the publication of the Easterlin's article which called attention to more complex relations between the absolute level of income and the subjective well-being than the economic theory would ever assume . There is the literature shown which finds the explanation why the relation - the absolute level of income and the subjective well-being - does not hold without exceptions. A special attention is devoted to the human behaviour: comparison of the individual's situation with the situation of his reference group, comparison of the individual's situation with the situation he was accustomed to in the past, the individual's adaptation to the new situation and change of his aspiration and on the overvaluation of the benefits from the achieved goal. The first characteristic is tested experimentally with use of the analogy: the income as the evaluation of the job performance, the mark as the evaluation of the student. The experiment did not prove that the comparison of the student with his reference group would have the influence on his own performance. The second part of my thesis is focused on the description of the relationship between the gross national income per capita and the satisfaction of the inhabitants from the...

Does the Role of the Rating Prior to the Announcement Explain Different Influence of Credit Rating Downgrades and Upgrades on Stock Prices?
Sedlář, Jan ; Andrlíková, Petra (advisor) ; Lelovská, Adriána (referee)
The thesis examines whether the role of credit rating prior to the announcement of credit rating change is the neglected factor explaining in large extent the paradox investigated in prior papers that downgrades influence the stock prices of company but upgrades not. It is motivated by the notion that credit rating changes from low credit rating classes influence the stock price of company more distinctively than changes from higher credit rating classes and there is proportionally more downgrades from low credit rating classes than upgrades. The large sample of credit rating changes including proportionally more upgrades from low credit rating classes than downgrades is collected and the results suggesting the influence of downgrades on stock prices of company and any influence of upgrades persist. Furthermore when controlled for credit rating prior to the announcement of credit rating change, magnitude of credit rating change, crossing the investment-speculative barrier, credit rating changes within and across credit rating categories, consecutive credit rating changes in the same direction and industry sector of issuer all the results are consistent with the original conclusions proposing significant stock price reaction to announcements of credit rating downgrades and no stock price response to...

Analýza fyzikálně - chemických ukazatelů jakosti vody vybraného vodního toku
Sedlář, Jan
The bachelor thesis on the analysis of physicochemical indicators of water quality deals with the monitoring of water quality in the steam o Malšinka at five sampling points. The samples of water were taken in two-month intervals from April 2017 to February 2018. The first part is made of literary research, which deals generally with water, legislation and characteristics of selected indicators – water temperature, oxygen, conductivity, nitrate nitrogen, phosphates, sulphates, iron. In the next part of the bachelor thesis describes water flow, natural characteristics such as climatic conditions, geology, pedological conditions, hydrology and fauna and flora. This section also includes a description of each sampling point. The last part deals with evaluation of measured values according to ČSN 75 7221 Classification of surface water quality and annex No.3 to Government Descree 401/2015 Coll.
