Microprocessor control of sensory platform
Konečný, Lukáš ; Zuth, Daniel (referee) ; Matoušek, Radomil (advisor)
This dissertation deals with a development of MCU position steering application of two servomotors and with data process evaluation from a connected sensor for distance measuring as well. The connected sensor is adjustable as for azimuth and elevation. Data from the sensor will be useful both for instant evaluation according to preset criteria and for additional possible processing at PC. The development is to be carry out at MCU ATmega128. HMI is represented with keyboard, LCD and joystick. The result of the dissertation is to be adjusted for practical demo. This research has been supported by the Czech Ministry of Education in the frame of MSM 0021630529 Research Intention Inteligent Systems in Automation.

Phase-correlation based image registration
Druckmüllerová, Hana ; Martišek, Dalibor (referee) ; Procházková, Jana (advisor)
Tato práce se zabývá použitím fázové korelace k určení vzájemné rotace, změny měřítka a posunu mezi digitálními obrazy. Fázová korelace je založena na Fourierově transformaci, proto je popsána Fourierova transformace funkcí definovaných na R^2 i diskrétní Fourierova transformace funkcí definovaných na konečném počtu bodů {0, 1, ... , N-1}^2, kde N je přirozené číslo. Dále je pozornost věnována modifikacím fázové korelace, díky nimž metoda umožňuje nalezení parametrů podobnostní transformace i mezi obrazy, které mají vysoký dynamický rozsah a slabě patrné struktury, obsahují aditivní nebo impulzní šum a jsou pořízeny pomocí různých snímačů a optických soustav. Obsahem práce jsou i modifikace metody pro snímky sluneční koróny pořízené během úplných zatmění Slunce, což patří mezi nejobtížnější úlohy registrace obrazů.

Design of aircraft power unit
Poledno, Martin ; Maňas, Pavel (referee) ; Nevrlý, Josef (advisor)
This diploma thesis deals with basic design and calculation of an aircraft power unit (APU). For desired shaft power the thermal cycle is calculated. Basic dimensions of compressor, turbine and exhaust system are calculated as well as thermodynamic parameters of air and hot gases along the motor. Corresponding compressor map, turbine map and characteristics of the exhaust system are designed. Based on these characteristics, an effective shaft power is being calculated in various off-design conditions. Dependency of the shaft power vs. altitude is also presented. All the calculations are made in MATLAB. Finally, simplified motor cross-section is created.

Implementation of ERP System
Lega, Lukáš ; Rain, Tomáš (advisor) ; Ivo, Ivo (referee)
Enterprise Resource Planning (ERP) was developed from the fifties of the last century. Mainly used was for accounting. Another milestone was seventies when there was added functionality of material management. The biggest extensions came in the nineties when there was a significant increase of servers performance and ERP systems could be more complex. Suppliers began to develop new modules for Customer Relationship Management (CRM), analytics named Business Intelligence (BI), Warehouse Management System (WMS) and others. Expansion of Internet and secure connections began also cause of develop the Electronic Data Interchange (EDI). ERP systems are more complex so implementation of this systems are more complex too because it extends to most processes in the company. Implementation starts by selecting an ERP system in relation to the processes maps of the company. Then it is necessary to manage whole process of the implementation and write target concepts of each parts. Equally important is the data preparation and cleaning of data base for migrate to a new ERP system. After programming, editing and parameterization of the required functions and processes following phase of testing. If all goes as expected and acceptance document is approved, ERP system is prepared to productive mode.

Positional Motion Control by means of 8bit uP
Janda, Petr ; Holý, Miroslav (referee) ; Matoušek, Radomil (advisor)
This thesis deals with positional control of DC motor Icla D065 of company SIG Positec Automation GmbH with aid of CAN-Bus and CANopen protocol. Individual parts describe general principle and standards of CAN-Bus and international normalized higher-level protocol CANopen for systems control. For control this motor was used microcontroller PIC18F4685 from company Microchip and developmental environment MPLAB® IDE. With used C language was made program for MCU control communication with a motor by support of CANopen protocol and its motion control. The result of this thesis will be used in solution of research project Intelligent Systems in Automation.

Automatic control for factory building heating
Prudek, Miroslav ; Voldán, Jiří (referee) ; Němec, Zdeněk (advisor)
The graduation thesis is focused on the automatic operating of heating of the production hall of První brněnská strojírnaVelká Bíteš, a.s. The thesis consists of an analysis of present state of the heating technology and solution of the general conception of the automatic operating of the heating. Integrated part of the conception is heat-up of the supply water and drain off of the condensation water from the air heating units. Outcome of this graduation thesis is a design of the algorithm for operating of the regulated system. Remote supervision and control of the regulated system shall be ensured by the visualization setting, which shall be implemented into the station of dispatching centre. The accuracy of the design of the part of regulated system shall be validated as a design of PID regulator with the use of “Matlab” program and it´s module “Simulink”. To set up parameters of the PID regulator, “Ziegler-Nichols” method shall be applied. The objective pay-off period of investments for regulation controlling system is figured out as a part of this thesis as well.

Energy simulation of solar collectors operation in a low-energy family house with warm-air heating
Pech, Ondřej ; Charvát, Pavel (referee) ; Jaroš, Michal (advisor)
The thesis deals with energy simulation of a solar energy system in a low-energy family house with warm-air heating. The simulations performed resulted in the assessment of the energy contribution of four solar systems with different types of collectors. The profitability and return of investment for the particular system have been evaluated based on investment costs and the savings gained. The theoretical part includes an introduction to the solar energy field, solar panel systems and the passive house concept. The practical part is devoted to description of the simulated object models as used in the TRNSYS environment, the simulation results evaluation along with the assessment of the economic return on investment. The conclusion recommendations regarding a suitable type and size of the solar panel with respect to the economic criteria chosen are given.

Measurement of transverse relaxation using spin echo methods
Škoch, Antonín ; Tošner, Zdeněk (advisor) ; Hanyková, Lenka (referee)
Title: Measurement of transverse relaxation using spin echo methods Author: MUDr. Antonin Skoch, Ph.D. Department: Department of Low Temperature Physics Supervisor: RNDr. Zdenek ToSner, Ph.D. NMR laboratory, of Faculty of science, Charles University in Prague Supervisor's e-mail address: tosner(o)karlov.mff.cuni.cz Abstract: The study of TI relaxation in systems with homonuclear J-coupling is complicated by modulation in the relaxation curve. This J-modulation can be removed when CPMG sequence is used and the period of repetition of refocusing pulse Tfulfils a condition r « * ( 1 ) Ai' where Av is the frequency difference of coupled nuclei. However, the condition (I) cannot be in practice always fulfilled. The aim of this work was to investigate J-modulation and relaxation behaviour of homonuclear J-coupled system in various parameters of CPMG sequence. Simulations based on numerical solution of Liouville-von Neumann equation and Redfield theory were performed. Relaxation curves of Chh group of citrate were measured on high-resolution NMR spectrometer. It was found that the suppression of J-modulation can be achieved also for T longer than required by the condition (1) providing that the refocusing angle in CPMG for both J-coupling partners 9^180ř. The simulations yielded conditions for T when J-modulation...
