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.

Power supply of electrostatic separator
Broďák, Kamil ; Pazdera, Ivo (referee) ; Huták, Petr (advisor)
The diploma thesis focuses on the problems of electric power precipitators. Due to their current dominant position, the work concentrates on the sources of single phase transformers operating at the frequency of 50 Hz controlled by thyristors. The first part describes the electrostatic precipitator and its principle. This is followed by a brief insight into the proposal for an electrostatic precipitator. The work also explains the high voltage source that is divided into a transformer with a rectifier and into a control box with power circuits and control circuits that provide the power supplied by a transformer. The work also offers an explanation of the HV source system that operates at different conditions. The last part suggests a proposal for cooling cabinet including thyristors, for power line control box resources, for a supply line and a line to the transformer.

Creation of Logistics Concept in a Business Organization with International Impact
Fojtíčková, Petra ; Ing.Petr Jašek (referee) ; Jurová, Marie (advisor)
The diploma thesis deals with the logistics concept in a selected company with a focus on distribution channels in international trade. The theoretical part of the work is focused on clarifying the concepts that are related to the issue. The analytical part is focused on the analysis of distribution with a focus on distribution channels to the individual countries in which it operates. In the last part of the work, based on the obtained and analyzed data, own proposals for solving the identified shortcomings are proposed.

Design and implementation of demonstration model "double inverted pendulum"
Slabý, Vít ; Brablc, Martin (referee) ; Bastl, Michal (advisor)
This thesis describes the process of rebuilding an experimental model of a single pendulum on a cart into the double pendulum on a cart. The control algorithm in MATLAB/Simulink environment for stabilization of the pendulum in the inverse position is designed. For this purpose, LQR state feedback control was implemented. Also method for swinging the pendulum into inverse position from stable state (swing-up) was designed. Feedforward method was utilised for swing-up control. In the thesis, functionality of these algorithms is shown.

Leadership and management of employees in the construction company
Bílková, Alice ; Lopata, Stanislav (referee) ; Linkeschová, Dana (advisor)
This Bachelor thesis deals with the theme "Leadership and management employees in a construction company." The essence of the theory is to briefly introduce the concepts of management, construction management, leadership and management of staff, use of the motivational tools, especially those incentives such as internal communication and education. At the same time I was engaged in an essential part of leadership and management, that is the evaluation of the workers and consequently the satisfaction that fundamentally affects the functioning and performance of workers in employment. In the empirical part, to verify and evaluate the given hypotheses, is used of quantitative and qualitative research. Qualitative interviewing is prepresented by the heuristic form or form of structured interviews. Controlled talks preceding the survey for the purpose of obtaining quantitative answers. The output of this thesis are the conclusions of a set of recommendations based on trends and experiences learned from the research that lead to improved climate in the leadership and management of co-workers in a construction company.
