Ice Hockey stadium
Chalupa, Vojtěch ; Šmak, Milan (referee) ; Barnat, Jan (advisor)
The aim of this diploma thesis is the design of the roofing of an ice hockey stadium situated in Žďár nad Sázavou. Plan view dimensions are 55 m x 77 m. The structural height of the roof varies from 10 to 17 m. The roof itself consists of pipe truss girders with a span of 55 m, which are supported by columns on each side. The girders are suspended by a load-carrying arch with a span of 96 m and a camber of 29 m through a system of pre-stressed cables. To determine the internal forces, structural analysis software Scia Engineer was used. Individual elements were then manually designed.

Testing parameters of stepper motors at different microstepping mode
Műller, Jakub ; Chalupa, Jan (referee) ; Klimeš, David (advisor)
This thesis deals with design and construction of test equipment that allows measurements of basic parameters of stepper motors. The first part is devoted to the search about the principle of operation of the hybrid stepper motor. For the analysis engine has been used a mathematical simulation model with real parameters in Matlab/Simulink. The next section is the design of mechanical and electronic form of the test facility with a description of the components used. The last part of this work is focused on measuring the excitation currents and measuring loss of steps at various control modes and microstepping.

Design of Power HIL unit for Li-pol cell simulation
Pribulla, Daniel ; Sova, Václav (referee) ; Chalupa, Jan (advisor)
This thesis deals with design and construction of a Li-po cell Power-HIL simulator intended for testing of a small wireless module's powering. The simulator is based on a battery model which includes the influence of temperature and battery degradation on battery parameters. To estimate model parameters a series of tests on real Li-po cell with capacity 250mAh were performed. Charging and discharging tests were performed by different temperatures of the battery. In purpose of this test a simple thermal chamber was constructed. Design of the power electronics of the device was tested in the Simscape library of the Matlab Simulink. The result is a working prototype of the simulator tested for charging and discharging of batteries with capacity in range 100-1500 mAh. The simulator can be controlled with graphical user interface capable of setting the battery parameters and real time observation of the model variables.

HIL Simulation of Electronic Throttle
Maliszewski, Michal ; Chalupa, Jan (referee) ; Sova, Václav (advisor)
This thesis deals with the Hardware in the Loop (HIL) simulation of an electronic throttle. In the following text its mathematical model for different options of friction and hardstops is deduced. Model parameters were obtained by measurement on the real throttle. In the next step the thesis aims on designing the suitable control algorithm, which is used for own HIL simulation. The output of the thesis is the choice of the best model with respect to accuracy and computation time of the simulation.

Desing of measuring of electric machine rotor temperatue
Chalupa, Jan ; Krejčí, Petr (referee) ; Vlach, Radek (advisor)
This bachelor thesis is focused on temperature measurement issues of rotating parts of electrical devices. Thesis includes proposition and implementation of hardware solution, which enables multi-channel temperature measurements using PT100 sensors. Measured temperature is transmitted into the user’s PC. Thesis also includes user software solution for Windows platforms. Hardware requirements are low. System is primarily determined for temperature test of electrical devices. It can be also used for long-term monitoring of devices in operating state. Transmitter was designed with following considerations. Minimal size, low consumption, mechanical and thermal endurance. These demands require comprehensive approach to the whole system solution.

Self-Service Business Intelligence in the Management of Business Informatics (MBI)
Chalupa, Pavel ; Pour, Jan (advisor) ; Bosák, Martin (referee)
The bachelor thesis is focused on the development of reference model MBI (Management of Business Informatics) exerted on the land of the Department of Information Technologies in the University of Economics in collaboration with the Department of Software Engineering CTU. The aim of this thesis is the introduction issues of implementation and operation of the Self-Service Business Intelligence solutions in the company. The thesis is divided into two parts. The first part briefly describes principles of the Self-Service BI solution, it defines its potential benefits and effects in the company and compares the possibilities of using Self-Service BI with traditional Business Intelligence solution. The second part is focused on the already mentioned expansion of the MBI model. There are introduced the most common tasks related to the implementation and operation of Self-Service BI in this part, their links to user roles and important factors that may be affected by this solution.
