Thermodynamics of ideal gases in Matlab
Zábojník, Jakub ; Klimeš, Lubomír (referee) ; Štětina, Josef (advisor)
In terms of bachelor’s thesis a toolbox of functions for basic computing in thermodynamics with ideal gases and their mixtures was built in environment of computer program MATLAB. Source code of these functions and their description are parts of this thesis. Among others fundamental characteristics of thermodynamic values and terms on which the creation of functions was built, and instruction for calling of functions are mentioned here. Functions in toolbox imaginary are divided to some groups. This dividing is results from principle of thermodynamic calculation. Functions from two neighbouring groups are directly tied together. For lucidity of function sequences and for functions usage and toolbox explanation the examples of using functions examples of functions usage in specific thermodynamic calculations.

FIELD II - modelling of the ultrasound field
Štrbík, Jiří ; Čížek, Martin (referee) ; Kolář, Radim (advisor)
This bachelor thesis presents the way of modelling the ultrasonic field with FIELD II package implemented in MATLAB 7 enterprise. The first part of the thesis provides the theoretical information about supersound. It describes the main properties of supersound and the processes that composse ultrasonic pulse. The principle and the significance of Doppler effect is also cleared up in this section. Finally, this part deals with ultrasonic probes, with their subdivision and their main parameters. In the second part of the thesis the FIELD II package is described. This part provides the information on the installation of the package and about the usage of the functions for modelling the ultrasonic field. This part also shows examples that illustrate the utilization of the package for teaching purposes.

The Application of Fuzzy Logic for Rating of Suppliers for the Firm
Zegzulka, Ivo ; Šťastníková, Adéla (referee) ; Dostál, Petr (advisor)
This thesis deals with the design of fuzzy system that can evaluate supplier of spare parts for service. The result should be applicable to a company Iveta Šťastníková - car and tire service. Primarily it should simplify operations associated with the selection of appropriate spare parts, tools and other equipment needed to operate with car service station. First, we introduce the theoretical basis for the paper, and then we go to the present state and the analysis itself. The result is a proposed solution which should correspond to the needs of the owner.

Thermodynamics of ideal cycles of IC engines in Matlab
Pavlíček, David ; Mauder, Tomáš (referee) ; Štětina, Josef (advisor)
Key aspect of this thesis is toolbox, which contains functions for calculate ideal combustion engine cycles. Thesis is divided into four parts. In the first part is briefly described history. The first chapter contains description of real combustion engine types. In the second part, which is covered by the second chapter, is located thermodynamic view. Third part is whole about MATLAB. From historical introduction through description of individual functions to example how toolbox can be used. In the last part is comparison of real combustion engine cycle with ideal one, which has been created by toolbox.

Toolbox for the cooperation of MATLAB and external simulation programs
Moravec, Petr ; Sekanina, Lukáš (referee) ; Oliva, Lukáš (advisor)
In this Master's thesis scripting interface of two programs CST Microwave studio and Ansoft HFSS for the purpose of analysis of electromagnetic structures is described. The work is focuses control of these programs with help of scripting languages and system's interface of MS Windows XP. Next the process of connecting programs with MATLAB is shown on commented scripts together with an example of complete analysis of a chosen problem, and the import and export of results results in MATLAB. Further the functions which form programming interface between MATLAB and simulation programs are designed and implemented. The interconnection layer makes the complete control of simulating programs possible using the function description published in the official documentation of used simulation programs. The layer is described in reference manual in detail and it is used for optimization with use of Particle swarm optimalization (PSO) of planar antenna model. Then there is presented another usage of the layer for an implementation of global optimization methods - SOMA and DE including suggestion of process for comparison efficiency of optimization algorithms on simple electromagnetic models.
