Artificial aorta for activity demonstration of intraaortal baloon contrapulsation
Bičiště, Jan ; Rampl, Ivan (referee) ; Zeman, Václav (advisor)
This dissertation work describes design and construction of simulated aorta device intended to demonstrate performance of the intra-aortal balloon catheter (IAB), and to test reaction of the contra-pulsation pump during simulated cardiac output in conditions of tachycardia, bradycardia and arrhythmia. The major part of the device is transparent plastic tube. The pressure pulses (waves) are generated inside this plastic tube to simulate real cardiac output. These pressure pulses are generated by step motor with membrane. The step motor is controlled by programmable control system AMiNi-E. Individual pressure pulses simulate cardiac output in conditions of tachycardia, bradycardia and arrhythmia. Required simulated cardiac output is selected by control switches. Generated pressure pulses are read by pressure sensor and are transferred to the control system of the configuration computer. Read data can be displayed as graphs in program Microsoft Excel. The intra-aortal balloon catheter (IAB) is inserted inside the aorta and is connected with contra-pulsation pump which on pressure pulse is responding.

Controling the dust exhaust of smeltery for recyclation of aluminum waste
Jakubský, Ondřej ; Nadrchal, Zdeněk (referee) ; Trnka, Vladislav (advisor)
The work deals with controlling and visualizing technology of dust exhaust of smeltery for recyclation of aluminum waste. In the first part of the work are analyzed the different ways of automatic control. Based on the analysis is proposed control system configuration, algorithm of control, communication interfaces and sensors of alarm, measurement and regulation. The second part deals with visualization and remote administration of control system. On the basis of selection for the visualization software is designed and implemented a system that provides visualization of technology, the archiving of measured operating values, events and errors.

Design and construction of automatic galvanic line
Vondruš, Jiří ; Janda, Marcel (referee) ; Melichar, Petr (advisor)
This thesis deals with the design of automated system of electroplating. The first part is centered on designing the technological process for this electroplating and the setout of operating vats. It also deals with the project of mechanical construction, electrical system, with the computing procedure and the optimum choice of gear for galvanic line model. The work includes the design of a DC motor controller, the computing procedure and the construction of heating element for vats heater simulation. The last part of this thesis offers an insight to the control system and the assembled program. In the addendum, the photo of the realized model, the wiring scheme, and the programme transcript for control galvanic line model can be found.

Aircraft Braking Systems
Kochtík, Martin ; Kaddour, Mirvat (referee) ; Třetina, Karel (advisor)
The main theme of my work is braking and function of brake systems when aircraft moving on the ground after landing until its complete cessation. In this work are explain the basic definitions and principles of braking systems for transport aircraft. Proceed the explanation of regulations and basic requirements that must be observed. And also there is analyzed the above-mentioned part of aircraft motion on the runway. There is described the principles of obstruction of the kinetic energy and their calculation method in a theoretical point of view and after that, there are described specific calculations of landing speeds for the selected aircrafts. Attention is also paid to the possibilities of using energy produced by airplane braking wheels and overall directions of further progress on the brake system for these transport airplanes.

Controllers design for plants with large time constants
Omelka, Vlastimil ; Rojka, Aleš (referee) ; Davidová, Olga (advisor)
This bachelor thesis aims to present a design of convenient continuous action controllers for plants. A brief summary of methods of design mostly in use is listed in the work. Selected methods are presented with more detailed description and are applied on four particular systems with different time constants. Furthermore the calculated values are being processed using MATLAB - Simulink program. The final readings are evaluated and compared with respect to the quality and precision of the regulation.

Numerical control of machine tools
Dlouhý, Rostislav ; Opl, Miroslav (referee) ; Blecha, Petr (advisor)
This thesis is focused on numerical control of machine tools. Control systems are shortly compared. There are three biggest manufacturers: Siemens, Fanuc and Heidenhain. Especially user benefits and opportunities of workshop programming are compared. The second part is focused on the choice of control system for the selected machine tool. I am applying the knowledge and the conclusions which I have reached in comparing different control systems. I chose two alternatives of the control system based from entered requests for the chosen machine tool.
