This bachelor thesis deals with the problematics of a low-potential heat from the energetics point of view. It also deals with the sources and subsequent use of the low-potential heat. First of all, the thesis mentions the origin of these sources and also describes where they can be found. Also the technologies, that are able to utilize this heat, like heat pumps and solar collectors, are mentioned in this part of the thesis. In its next part, the bachelor thesis deals with use of the waste heat for heating and production of electrical energy. In the last part, the thesis presents the project that introduces a specific concept of the system for object heating from the waste heat.

Process Calibrator M143 - Climatic Testing
Dojava, Václav ; Bartoň, Jan (referee) ; Havlíková, Marie (advisor)
Subject of the bachelor thesis are the climatic testing of the M143 calibrator. Theoretical section of the thesis is concerned with the analysis and description of the norms used during climatic tests of electronic devices. Thesis then continues by describing properties and functions of the M143 calibrator and the Caliber programme, which is performing automated measurement during the climatic tests, on the basis of the designed calibration procedure. Practical section of the thesis describes the designed testing points and climatic conditions, which are adjusted during the testing. In this section the testing points are implemented to the Caliber programme. Last section contains the analysis and evaluation of the measured data gained during the climatic testing. From these measured data, we are to determine, whether the M143 calibrator is within the specifications stated by the manufacturer in different climatic conditions.

Design of audio power amplifier with Bluetooth connectivity
Bartoň, Jan ; Šotner, Roman (referee) ; Brančík, Lubomír (advisor)
This bachelor‘s thesis deals with the task of designing an audio amplifier, operating in class D, with a nominal output power of 2 x 80 W with Bluetooth connectivity, supplemented by an equalizer and a state display. A power supply and a user interface are designed as well. At first, research regarding audio amplifiers is made, followed by a more thorough description of class D operating principles. Afterwards the actual synthesis of the desired amplifier is presented, followed by the power supply design procedure. The correctness of the synthesis is later verified by simulations in PSpice and LTSpice. Theoretical design is then practically built, and its parameters are confronted with expected values by measurements.

Legal regulation of special funds in collective investments focused on the function of a bank as depositary
Barton, Jan ; Kotáb, Petr (advisor) ; Kohajda, Michael (referee)
104 Resumé The aim of the master thesis (Legal regulations on collective investing with a view to the role of bank as a depositary) is to analyze contemporary situation of collective investment in European and national context in the light of recent developments and trends in the world financial markets. The main purpose to pursue this subject matter and also the reason why this master thesis has been written is to obtain a clear overview of all regulations and principles (not merely at statutory level) which might affect the activities connected with founding, operation and investment decisions of UCITS and non-UCITS collective investment entities. Second part of the thesis, after the introduction, describes shortly the historical roots of collective investing, followed by a separate subchapter covering the general principle of collective investing through which all other parts of the thesis are knotted together. Third part provides a short structuring of the collective investment entities from a legal point of view, taking into account different characteristics of corporate entities engaged. Also diverse investment strategies and the increasing importance of collective investing within financial market's intermediary functions are mentioned hereby. Fourth part is consequently devoted to the pure...

Novel approaches to chemical modification of diamond surface
Bartoň, Jan ; Cígler, Petr (advisor) ; Řezanka, Pavel (referee) ; Stehlík, Štěpán (referee)
1 Abstract Diamond is a unique material for its physical and chemical stability. However, many advance applications rely on surface functionalisation. Here, two types of diamond were modified on the surface - thin layer of chemical vapor deposition (CVD) and nanodiamond particles (NDs) high pressure and high temperature (HPHT). The aim of CVD surface modification was to prepare photosensitised, conductive, diamond electrodes for dye sensitized solar cells (DSSC). For this purpose, a thin diamond layer doped with boron was deposited on the silicon wafer. Boron doping provided p-type (semi)conductivity to diamonds. The surface of the diamond was hydrogenated with H-plasma, and a short carbon linker with a protected amino group was UV-photografted to the surface. In another study, a photoconverting dye (P1) was covalently attached to the amine-linker. Furthermore, a dye designed based on donor-π-acceptor (D-π-A) concepts was attached to the surface. Finally, a systematic study was done for differently conductive diamond layer and the underlying silicon wafer These experiments gradually lead to the highest ever reported photocurrents of 6.6 µA cm2 for a flat photosensitised boron-doped-diamond (BDD) electrode. Monomolecular layer surface functionalizations on CVD diamond are difficult to detect or even quantify...

Quality Monitoring Device for Electrical Power Networks
Bartoň, Jan ; Šimek, Václav (referee) ; Vašíček, Zdeněk (advisor)
The diploma thesis deals with the parameters of electricity quality. The aim of this work is to design and implement a prototype device that will allow remote measurement of power quality. The proposed system uses NB-IoT technology for data transmission. The system enables remote measurement of important parameters of electrical energy, such as the magnitude of the supply voltage or the frequency of the electric network. The device can measure electric current, average voltage values and detect dip / swell voltage events. The device reads a sampled electrical signal suitable for harmonic analysis. The device has started to meet the requirements for measuring device of class S according to EN 61000-3-40.

Optimization of voltage amplifier
Malík, Luděk ; Bartoň, Jan (referee) ; Šedivá, Soňa (advisor)
This bachelor thesis concerns the simulation and optimisation of a voltage amplifier as a part of a multifunctional calibrator 9010, which has been recently introduced by Meatest s.r.o. company. The simulation is executed with LTspice software. LTspice itself and the basics of its usage are also described in this thesis. Furthermore, this thesis contains the theoretical analysis of used components and their connetions. The thesis also depicts the schematics of the above mentioned voltage amplifier supplied by the Meatest s.r.o. company. The thesis contains measurements of selected properties of the voltage amplifier from the 9010 calibrator and their comparison with the results of the simulation. The optimisation concerns these selected properties and compares them to the original qualities of the calibrator 9010 voltage amplifier.

Optimization of single-page application startup
Bartoň, Jan ; Švikruha, Patrik (referee) ; Ilgner, Petr (advisor)
This thesis concerns with optimalisation of launching the single page JavaScript application Kentico Kontent. It especially focuses on dividing JavaScript libraries and packages into independent files according to certain criteria. These adjustments to the application are divided into several scenarios. For every scenario, six types of measurements have been carried out, due to which the impact of the change on the speed of loading the application and the amount of transferred data from server to client was found. The result of this thesis is a proposal of adjustments which lead to a faster launch of the application, due to a smaller amount of data being transferred from the server, therefore the application can use the browser cache more effectively.
