Design of the File Backup Strategy for a Company
Svoboda, Jiří ; Jonáš, Martin (referee) ; Ondrák, Viktor (advisor)
The content of this thesis is a complete design of the file backup strategy for the company named GrowJOB s.r.o. The thesis is divided into theoretical and practical part. The first part contains the theoretical basis for the file backup issues. The practical part is focused on the file backup strategy design itself, including the data classification, guidelines, integration into the company’s organization structure, design of the backup processes and choice of the technologies regarding their total cost.

Analysis of a Selected Company Using Time Series
Hejlová, Monika ; Svoboda, Jiří (referee) ; Doubravský, Karel (advisor)
Bachelor's thesis analyses the company Elektrizace železnic Praha a. s. from 2001 to 2009. Analysis of the company is divided into two parts. The first part deals with the analysis of the economic indicators. The second part focuses on the analysis of the selected information in the sequence by using statistical methods. This section also contains the foreseeable development of the company in the years 2010 and 2011. The work contains proposals for improving the financial situation of the company.

PLC Control of Robotic Manipulator
Krajcar, Tomáš ; Svoboda, Jakub (referee) ; Hynčica, Ondřej (advisor)
The thesis is focused on the design control of a 3-axis robotic manipulator. The manipulator is used for transporting the moulded part from a moulding machine to a conveyor belt. A manipulator has 3 asynchronous motors controlled by one frequency changer. A PLC is designed for full control of this operation. A PLC uses a real time operating system, which allows it to work on several tasks at the same time. A PLC has Modbus TCP/IP communication with HMI. A PLC has Modbus TCP/IP communication with HMI. A manipulator communicates with a moulding machine via a EUROMAP 12 interface.

Alternative sources of nuclear energy
Svoboda, Josef ; Zlámal, Ondřej (referee) ; Katovský, Karel (advisor)
In places where it is not possible to use conventional production and distribution of energy, autonomous sources take over. Most of autonomous sources use solar energy, wind energy and other renewable resources. For applications such as special missions into outer space the usage of conventional sources is not possible. Except for powering special satellites, unconventional nuclear sources are also used in autonomous unmanned objects located in distanced areas with extreme natural conditions. It is also used in unusual propulsions of ground, water and air machine. These vehicles are for example pacemaker powered by radioisotope source, submarines, aircrafts and other vehicles supplied by nuclear reactor of unconventional conception. In this bachelor thesis there are globally summarized questions connected with unconventional sources of nuclear energy with detailed description of chosen parts. This work is concerned with finding more efficient machinery for conversion of heat energy supplied by radioisotope decay to electric energy.

Sensorless velocity control and positions of d.c. low-power brush motor
Svoboda, Jan ; Hanák, Pavel (referee) ; Prajzner, Václav (advisor)
This bachelor's thesis focuses on sensorless control of low load brushed DC motor that is used in the actuators made by the Honeywell company. The first part provides an introduction into motor control and common used methods of speed and position sensing of brushed DC motor. Sensorless method of sensing described in this work is the detection of commutation pulses from the signal of motor current. These pulses are caused by brushes leaping over the commutator bars. Correct evaluation of commutation pulses can provide the information about velocity and position of the motor. This relatively new method of detection of commutation pulses is investigated and arising problems are demonstrated on measured samples of signal. Suitable methods of signal processing are then proposed. Infallibility of these signal processing methods is then proved on the set of signals measured under circumstances of supply voltage and abrasion. Then it is decided which signal processing method that sensorless control system can use is the best.

Close Future
Svoboda, Jakub ; Šrámek,, Jan (referee) ; Zet, Martin (advisor)
For Bachelor thesis I chose a pretty hot topic, which currently Europe by storm and it is a migratory crisis. To handle this issue, I decided to use the form of the short film genre of post-apocalyptic movie.

Tracked chassis of a forwarder
Svoboda, Jan ; Pokorný, Jan (referee) ; Kašpárek, Jaroslav (advisor)
The thesis describes the design of a modular track undercarriage system for a forest utility vehicle called the forest forwarder. In the introduction there is a research study which reviews a variety of design options. The main part of the thesis describes the 3D model created in the Catia V5 programme. The model was subjected to an analysis of dynamic effects by simulated use of the track undercarriage system in the MSC Adams programme. A selected part of the undercarriage was analyzed by the finite element method in the Ansys Workbench programme. Drawing documentation of some of the components is included at the end of the thesis.
