Nonlinear Control of Complex Systems by Utilization of Evolutionary Approaches
Minář, Petr ; Ošmera, Pavel (referee) ; Oplatková,, Zuzana Komínková (referee) ; Matoušek, Radomil (advisor)
Control theory of complex systems by utilization of artificial intelligent algorithms is relatively new science field and it can be used in many areas of technical practise. Best known algorithms to solved similar tasks are genetic algorithm, differential evolution, HC12 Nelder-Mead method, fuzzy logic and grammatical evolution. Complex solution is presented at selected examples from mathematical nonlinear systems to examples of anthems design and stabilization of deterministic chaos. The goal of this thesis is present examples of implementation and utilization of artificial algorithms by multi-objective optimization. To achieve optimal results is used designed software solution by multi-platform application, which used Matlab and Java interfaces. The software solution integrate every algorithms of this thesis to complex solution and it extends possible application of those approaches to real systems and practical world.

Datalogger with parallel data logging
Havlena, Marek ; Minář, Petr (referee) ; Zuth, Daniel (advisor)
This Bachelor's thesis is dedicated to the design and implementation of the Datalogger module, which stores data in two different memory storages. First memory storage is solved by using an SD card and the second is the internal EEPROM memory of the microcontroller. It also deals with data synchronization between these memory storages. Communication between the cards is through the SPI bus and communication with the module is provided by a serial interface designed by USB transmitter (UART).

4D Cinema - animation of omnidirectional mobile robot
Ferjanc, Jan ; Minář, Petr (referee) ; Matoušek, Radomil (advisor)
This bachelor thesis deals with creating a 3D model of a three-wheel mobile robot and shows the design for it´s motion. The construction of the robot will be based partly on the existing prototype. The design is partly based on student´s own invention. The modeling and animation environment will be the Maxon Cinema 4D software. The resolving kinematic animation and wheels will be made using the Xpress plugin.

Methods of Machine Tool Thermal Error Compensation
Hanzal, Jiří ; Hermanský, Dominik (referee) ; Minář, Petr (advisor)
Thermal error caused by the thermal deformation is one of the most significant factors influencing the accuracy of the machine tool. This paper presents an overview of the methods of measurement, regulation and compensation of thermal errors. It also deals with the research of research centers and their projects. At the end of the thesis we are dealing with measuring of temperature deviations on machine tools MCV 754 Quick. For the tested machine tool, a methodical proposal of temperature compensation was designed using the grey neural network model with convolution Integral. This paper aims to give a basic introduction of the whole process of the spindle thermal error compensation.

Speech Recognition (digit)
Kantar, Martin ; Minář, Petr (referee) ; Matoušek, Radomil (advisor)
The aim of this diploma thesis is to explain what speech is and what are its constituents. I mention commonly used methods which are used for preparation of signals which we use for recognition. Schematic examples show principles of current recognizers of speech, their advantages and disadvantages. I made speech recognition program for 0-9 numerals in Matlab for neural nets learning.

Distributed Computing by force of Action Script
Minář, Petr ; Kuba,, Martin (referee) ; Matoušek, Radomil (advisor)
This Master thesis deals with designing and realization of optimalization software in ActionScript 3.0 background. The designed applications realized in terms of computation by standalone and distributed variant and by means of chosen heuristic method called HC12. For verification of a function and performance was select set of testing examples. The main purpose of the work was create public clients in the network internet and calculated partial computing by it. The completed clients are selected by competence and carry on tasks. This research has been supported by the Czech Ministry of Education in the frame of MSM 0021630529 Research Intention Intelligent Systems in Automation.

Non-contact temperature measurement
Sládek, Vojtěch ; Minář, Petr (referee) ; Hermanský, Dominik (advisor)
The aim of the thesis was the study of non-contact temperature measurement and the use of this measurement in the field of production machines. The first part of thesis includes concepts and definitions that are necessary for familiarization with the issue. In the second, practical part, contact and non-contact measurements were compared in two experiments. In the first one the machine frame was measured, on which the thermal load was simulated, the emission was determined, which was compared with emissivity from the tables. In the second experiment, the temperature gradient of the ball screw was measured during the ball screw operation and was determined emissivity, which was again compared with the table values. The conclusion of the thesis summarizes advantages and disadvantages of non-contact measurements that have been verified in practice.
