ECG Wave Delineation
Trnová, Kateřina ; Provazník, Ivo (referee) ; Kozumplík, Jiří (advisor)
This thesis deals with the detailed measurement of one cycle of the ECG signal. data samples of the beginning and end of major sections of this cycle are obtained from the values referred to in the database TESTRO. There is found a representative cycle. The text describes basic types of measuremend intervals, principles of multiple methods of measurement and description of the implemented program. Algorithm for measurement of functional units of ECG cycle signal, which was designed, is based on the detection of trend growth, of the field of signal using the first difference. Functionality was tested on a standard CSE database.

Waste heat to power technology
Kůra, Tomáš ; Máša, Vítězslav (referee) ; Konečná, Eva (advisor)
This bachelor thesis focuses on the methods of waste heat conversion to electrical energy. There are presented and described so far known methods that generate power via mechanical work and methods converting power directly from heat. The thesis also contains an overview of case studies for studied technologies. Finally, all the findings are summarised, the factors influencing the applicability of each technology are presented, and the possibilities of the technology application in the industry are evaluated.

Synergetics and Self-organization in the Economy
Balúch, Pavel ; Matušková, Kateřina (referee) ; Janíček, Přemysl (advisor)
The master thesis focuses at analysis and research of synergy and self-organization in economics. The motivation for the thesis was joining Czech Republic and other nine countries to the European Union on May 1st, 2004. The primary aim was to analyse the problem and on a model example,assuming "ceteris paribus", confirm or refute the thought, that joining the European Union has positive synergic effect for newcomers. The second meaning of synergy is solved as a sub-problem in the master thesis, where the use of synergy in logistics was analysed and opportunities improving the current situation were suggested.

Study and comparison of CNC control systems
Nytra, Tomáš ; Vetiška, Jan (referee) ; Bradáč, František (advisor)
The goal of this bachelor’s thesis is to create research of state-of-art of implemented CNC cycles of controll systém. At first the basic problematice of programming numerical control with possibility of own programming. Then the thesis is focused on properties of control systems of companies Beckhoff and Siemens. There are analyzed functions of individual cycles, their features and parametrs, finished with mutual comparison. Ending of thesis is devoted to the development of a macro for two missing cycles of Bekchoff system.

Graph theory and its applications
Huclová, Alena ; Karásek, Jiří (referee) ; Pavlík, Jan (advisor)
It is often necessary to be oriented in the complicated relations between parts of a unit. This problem can be solved by the graphs’ theory very well. Graph G is an ordered pair (V,E) where V is a non-empty set of vertices (our parts of the unit) and E is a set of two-element subsets of the set V called arcs (i.e. relations between parts of the unit). G= (V,E) The graph aplication is frequently hidden. It is not found in the solution of the problem, but could be used to express and substantiate it quite easily. In my work I will deal with optimization problems of a graph. Problem of the maximum network flow that we solve using directed graph can be an example. As for non-directed graphs, we will be interested in the search of a minimum frame of a graph.

Workflow with process control support
Babička, Michal ; Jirsík, Václav (referee) ; Holek, Radovan (advisor)
The aim of this thesis is to find a system solution for process control within the information systems on the basis of workflow. The solution is needed for an information system based on MySQL and PHP programming language. Process verification should proceed automatically on the basis of life cycles of the entities defined within the information system. The solution should be applicable on any process and it should also be transparent and simply changeable.

Cyclic acceleration method for electrical machines measurement
Ředina, Ondřej ; Ctibor, Jiří (referee) ; Červinka, Dalibor (advisor)
The bachelor thesis deals with the cyclic acceleration method of measuring and loading electrical machines. The thesis contains a description of the measuring method and processing of measured data. The application of the method was realized in the company AVL Moravia s. r. o. The processing of the measured data in the form of a sine wave was performed in the MATLAB program. At the end of the thesis are summarized the inaccuracies of measurements and following optimization of this method.

ECG Wave Delineation
Trnová, Kateřina ; Provazník, Ivo (referee) ; Kozumplík, Jiří (advisor)
This thesis deals with the detailed measurement one cycle of the ECG signal from the known beginning and end of each major wave of this cycle of the values listed in the database TESPRO. Another objective of this work is to find a representative cycle. The text describes the basic types of measurement intervals, principles of multiple methods of measurement and description of the program, which was implemented. Algorithm for Measurement of function-al units cycle of ECG signal, which was designed based on the detection of trend growth in the field of signal using first differences. Functionality was tested on a standard database CSE.
