Laboratory Pulse Power Supply Controlled by Microcontroller
Chytil, Jiří ; Kubíček, Michal (referee) ; Šebesta, Jiří (advisor)
This project deals with design of switching laboratory supply controled by PIC microcontroler. It consist of three modules: control unit and couple of power modules. Each of the modul is controled by PIC18 microcontroler. Device should work autonomicaly or it can be connected with PC via USB. Output paremeters 0-20 V, 0-1 A. The device has been designed with regard to minimal power consumption.

Evaluation and Development of Employees in Organisation
Korčeková, Adéla ; Palát,, Milan (referee) ; Rašticová, Martina (advisor)
The content of thesis is to analyze the process of evalution and development of employees in the organization. Education of employees is an important constituent part of efficiently functioning business. Theoretical part provides information about education, evaluation, care for employees and about performance management. Analytic part was focused on an organization in which the education of its employees is integral as it is very much influenced by the develpoment of technological process. Research, which was executed within the organization, is to reveal deficiencies that occur in process of evalution and education of employees in the organization. The last part was devoted to summary and suggests how to eliminate deficiencies.

Laboratory module of class D amplifier with PWM modulation
Barcík, Peter ; Petržela, Jiří (referee) ; Kratochvíl, Tomáš (advisor)
This bachelor’s thesis describes basic functional blocks of class D audio amplifier. Project also discuss about design of module class D audio amplifier with PWM modulation. As this audio amplifier is going to be a laboratory module, it is necessary to divide design into designs of individual functional blocks. Finally project describes design of output LC filter which is also simulated in PSPICE program. This thesis include complete construction details. Measurement results are shown in standard protocol.

Phase shifted harmonic oscillators for practical education
Hudec, Marek ; Petržela, Jiří (referee) ; Šotner, Roman (advisor)
This thesis focuses on designing a laboratory preparation for the study of phase-shift oscillators. The first part of the thesis comprises a theoretical discussion regarding the given problem. The laboratory preparation will include two types of oscillator circuits. An operational amplifier will be used as the amplifying element together with an RC feedback loop in one type of circuit whilst the other type will consist of operational transconductance amplifier employed as inverting amplifiers and generating feedback. The second part of the thesis includes the actual design of the preparation. The design process covers construction stage of the preparation, calculation of the component parameters necessary for oscillation to occur, simulations of the individual circuits along with THD analysis as well as with analysis of manufacturing variances. The second part of the thesis also contains the design of a separate block of all-pass filter. The simulation results will be verified experimentally, on a printed circuit board. In the last part of the thesis, I will evaluate and intercompare the theoretical, simulation and practical results.

Corporate Culture of the Job Agency and Proposals for Its Improvement
Malinová, Michaela ; Kubjátová, Ing Pavla (referee) ; Konečný, Štěpán (advisor)
The diploma thesis deals with the corporate culture of a selected job agency and its values. The theoretical part is based on the studied literature to explain the issue of agency employment, human resources and corporate culture as a factor that affects the efficiency and performance of the organization. The practical part analyzes the responses of the company's core employees from conducted semi-structured interviews. This feedback about the corporate culture and its perception by the employees themselves compared to management's expectations provides suggestions for improving the in-house climate and thus increasing labor productivity.

Proposal of Communication System in Company
Černá, Tereza ; Klech, Jan (referee) ; Zich, Robert (advisor)
Master´s thesis analyses modern methods of communication in company management. The objective is to discover out the crucial defects of this issue and to outline possible solutions which would improve the weaknesses – of internal communication. The master´s thesis consists of three parts: The theoretical part is concerned about communicational instruments which have been used by the operational company ČEPRO, a.s. The analytical part describes implementation of communicational instruments in the company. (external communication, internal communication, crisis communication and communication during the new product implementation) The proposal part recommends appropriate elements for efficient communication within the current communication system in the company.

Design of regulated laboratory source with current measurement
Panáček, Jiří ; Šteffan, Pavel (referee) ; Magát, Martin (advisor)
This bachelor thesis deals with problematic and design of linear laboratory power supply. The first impulse start design of this device was requirement of simple and low cost laboratory power supply with good performance for debugging and measuring electronic circuits. This design keeps modern trend in lab power supplies with driving via microcontroller. This solution makes device easy to control and it is possible change program equipment.

Modelling and control design of mechatronics systems on state-space
Ertl, Lukáš ; Hadaš, Zdeněk (referee) ; Houška, Pavel (advisor)
This work is concerned with modeling of simple mechatronic’s systems in state space and with designing their controls. In work is described a method for constructing the state model of direct current motor with programs MATLAB/SIMULINK and NI LabVIEW. There is designed the control for realized model and this control is verified in simulation. Later are model and its control, verified on real system.
