Experimental analysis of a fixed beam dynamic behavior
Poduška, Jan ; Houfek, Lubomír (referee) ; Březina, Lukáš (advisor)
This thesis is dealing with analysis of dynamic behavior of a fixed beam. An analysis of the applied mathematical model is proposed in the work. The mathematical model is then realized in MATLAB programming environment. Modal frequencies and mode shapes are con- sequently computed and results are compared to those obtained from the experimental modal analysis.

Description Methods for Electrical Systems and Their Solving
Křižka, Jakub ; Němec, Zdeněk (referee) ; Šeda, Miloš (advisor)
The objective of bachelor thesis is a searching description of methods, which are usually used for calculation of circuit variable values in electric circuits. At the beginning is thesis concerning with description of individual components (power supplies, electronic components) used in electric circuits, then also with analysis of rules, which are the fundamental for a calculation of values in electronic circuit – Ohm’s rule and Kirchhoff’s rules. Indivisible part of thesis is also summary of special methods, such as method of loop currents (mesh analysis), method of nodal voltage (nodal analysis) etc. and their demonstration on examples of electric circuits. The structure of thesis is coursebook and gives successive summary of information in area calculations of electric circuits.

Design and implementation of education model "Oscilator 1 dof"
Deďo, Michal ; Houfek, Lubomír (referee) ; Grepl, Robert (advisor)
The purpose of bachelor’s thesis is the design, implementation and testing of the educational model oscillator with one degree of freedom ", which should provide students with the possibility of closer assimilation of events generated by the oscillation, as well as to familiarize the student with the control model through Real Time Toolbox and evaluating the results of measurement. Work should provide students with real-time overview of these problems, which, in the future may bring to light the causes, or even prevention of disorders caused by oscillation.

Data glove: VRML visualization and design of electronic circuits
Štěpánek, Jan ; Bezdíček, Milan (referee) ; Grepl, Robert (advisor)
This work deals with designing and assembly of electronics of a data glove and creation of a hand visualization which projects a real-time state of user’s hand. Realization was a team effort of two students. The division of tasks is described in the chapter called Stanovení cílů práce. The beginning of the work is dedicated to a background research in the field of data gloves. Next chapters describe creation of the model of virtual hand. This model‘s task is to project real-time state of user’s hand based on data received from the flexure sensors and MEMS accelerometer. Communication with PC is realized through BlueTooth serial port virtualization. Mathematical model created in Matlab processes data received from the glove and calculates the values of the positions of the individual parts of hand. Matlab also served for development of a graphical user interface which enables the user to utilize the glove.

Modeling of DC motor in MATLAB/Simulink
Kunovský, Martin ; Kerlin,, Tomáš (referee) ; Hubík, Vladimír (advisor)
This bachelor’s thesis deals with the direct current motors, their properties and modelling. For modelling mathematic modul of direct current motor was created, which is linked to H-bridge and managed of PWM signal. After that general user environment GUI was created, which can run simulation after setting primary motor characteristic, and we can monitor it. This is executed in environment Matlab&simulink.

Octave and Matlab comparison in terms of basic mathematics
Zahradník, Radek ; Grepl, Robert (referee) ; Krejčí, Petr (advisor)
How is mankind grow older, its knowledge about nature, which in it lives, is getting deeper. Unfortunately human brain in itself became short for solving modern problems and we have to help ourselves with computers and modern computerised methods. But computers themselves can not solve the problems. We need to equip them with adequate software. Goal of this work is to compare Octave and Matlab systems in part of compatibility and in the solvings of practical problems.
