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.

Program for Training of Dactyloscopic Experts
Bartoň, Jan ; Drahanský, Martin (referee) ; Lodrová, Dana (advisor)
This work deals with the design project and the creation of user interface of a programme for the training of dactyloscopy experts. The first chapters describe historical and technical evolution of dactyloscopy. Then the work explains the methods and concepts necessary for understanding and elemental orientations in determination of fingerprints. The final chapters present a proposition of possibilities in how to obtain and represent the results in a comprehensible form. The conclusion of the work is dedicated to tests and evaluation of the results.

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.

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.

Thermostat on LinkIt Smart Platform
Bartoň, Jan ; Šimek, Václav (referee) ; Vašíček, Zdeněk (advisor)
The bachelor thesis deals with the automation of heating regulation in the household. The goal is to design and implement a prototype of a embedded system to enable the automation of the heating control process with the emphasis on low acquisition costs. The proposed system is used to control the eQ-3 MAX! wireless radiator thermostats. The user interface of the system is the touch screen. As well as iOS mobile application that allow remote control of the system. A prototype of a Wi-Fi sensor is designed and implemented to measure temperature. The work includes hardware and software design of individual parts of the system and their implementation. The resulting system is a good basis for a low-cost system for comprehensive home automation.

Measurement of precise capacitance decade in environmental chamber
Schinneck, Jakub ; Bartoň, Jan (referee) ; Havlíková, Marie (advisor)
This bachelor’s thesis deals with the control capacitance decade in a climatic chamber. The theoretical part introduces a capacitance decade M525 of the MEATEST company and the program Caliber of the same company. It introduces the methods of capacitance measurement. In the bachelor’s thesis there is the calculation of the uncertainty of measuring devices. On the basis of the lowest uncertainty, we choose the most suitable measuring device. The practical part describes the measuring with the use of prepared procedure for verification of the capacitance of programmable decade. The last part contains the evaluation of the measurement results and their comparison with the manufacturer's specifications.

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.
