Measuring and evaluation with platform CompactRIO and LabVIEW
Kantor, Pavel ; Janda, Marcel (referee) ; Huzlík, Rostislav (advisor)
This bachelor’s thesis deals with design and realization of measuring program for measuring EC motor per development environment LabVIEW. The thesis provides short introduction to the LabVIEW environment, shows potential of FPGA and of its use on the CompactRIO platform. It describes methodology of measurement and mentions application possibilities of this platform to the LabVIEW environment. Further, the thesis deals with sorting types, construction and function of EC motor. It mentions eventual problems, which can appear during the solving of measuring program, describes from basics the creation of the program and explains all function of all program parts.

Vibration of rolling bearing
Otoupalík, Jan ; Ripel, Tomáš (referee) ; Krejsa, Jiří (advisor)
The thesis deals with vibrations caused by geometric defect and fatigue damage of rolling element bearing. Hardware for vibration measurement is tested on 25 new pieces of NJ 304. Second part of the thesis examines if measuring of bearing vibration can help to detect a geometric defect. Geometric defects are detected according to a spectrum of vibration but the results are not absolutely exact. The possibility to detect geometric defects by measuring vibration has not been proven. The end of project tests diagnostic methods for rolling element bearings. The bearing defect was simulated to demonstrate bearing failure frequencies, envelope method and vibration spectrum.

USB miltimeter with microprocessor
Samek, Martin ; Kolka, Zdeněk (referee) ; Kovář, Jan (advisor)
Topic of my terminal labour is a proposion of multimeter and its resulting connection by the help of bus USB. When proposing the multimeter there was a tendency to use a minimal number of component parts to conserve a good protection against a bad usage in application. The most widespread busbar USB is used for connection of the multimeter and a computer. Standard HID is used for communication, for that it is not neccessary to install any system drivers.

Analysis of the seismic velocity field
Kratochvíl, Pavel ; Mekyska, Jiří (referee) ; Smékal, Zdeněk (advisor)
Seismic velocities are an important prerequisite for seismic processing as a method for hydrocarbons accumulations detection. Seismic velocities are often displayed for mutual comparing, improvement checking, they are filtrated and recalculated for its different characteristic determination. This work deals with basic seismic propagation laws, the meaning of velocities in different stages of seismic processing and this theoretical background is followed by a proposition of method for calculating and displaying of stack velocities.

Analysis of records management systems in multinational organizations in use
Žáček, Jan ; Kunstová, Renáta (advisor) ; Jakeš, Jiří (referee)
The thesis is focused on the analysis of records management systems in use in finance departments of two multinational companies. The aim of the thesis is to describe differences between Oracle and SAP accounting systems functionality in relation with records management, to compare individual solutions in companies and to describe improvement potentials. The thesis is divided into theoretical and practical sections. In the theoretical section are described definitions of basic terms, the purpose, functions and benefits of the records management component and its integration into ERP system. The thesis also describes basic legislative requirements and standards relating to records management. Practical section is focused on the analysis in companies. There are described analysis methods, company characteristics, applications and technical devices used for the records management in finance departments, business policies relating to records management, types of records and their handling. There are also described problems and shortcomings of the usage of records management systems in companies. The final section is devoted to summarize gathered knowledge and to the analysis evaluation.
