Digitally controlled AC voltage source
Dalík, Vladimír ; Čejka, Miloslav (referee) ; Beneš, Petr (advisor)
The thesis deals of microprocesor controlled instrument for measuring. In general it is about of controlling instruments and their usage in standard industry. laboratories and measuring systems. The first part contens theoretical knowledge of controlling instrument, his funtions and describes circuitry of sources of AC voltages. This part describes blocks of instrument and basis connecting in system of instrument. Each block is described with examples in praxis. Examples contents typical connecting and their problems out of view in parameters of instrumenr. In this part is whole theory of analysis and practical using separately parts of instrument. Next part is aimed at searching of interrelationship between the teoretical model of source that described by different circuits and practical connections with electronic parts. These part analyse concrete design with exactly sized parameters and connections. In last part contents describing of measuring at prototype. The appendix contains schematics and boards with electronic parts and test reports of measuring output voltage and frequency with required accuracies.

Data compression
Krejčí, Michal ; Havlíková, Marie (referee) ; Čejka, Miloslav (advisor)
This thesis deals with lossless and losing methods of data compressions and their possible applications in the measurement engineering. In the first part of the thesis there is a theoretical elaboration which informs the reader about the basic terminology, the reasons of data compression, the usage of data compression in standard practice and the division of compression algorithms. The practical part of thesis deals with the realization of the compress algorithms in Matlab and LabWindows/CVI.

Spectral anlysis with superesolution
Vintera, Jiří ; Macho, Tomáš (referee) ; Čejka, Miloslav (advisor)
VINTERA, J. Spectral anlysis with superesolution. Brno: University of Technology, The Faculty of Electrical Engineering and Communication, 2008. 85 p. Master’s thesis. This thesis deals with the topic of super-resolution spectral analysis in the Signal Processing Toolset. The Signal Processing Toolset is a software component of the LabVIEW 8.1. program equipment. The thesis consists of three main parts. In the first part the basic theoretic concepts of the Model-Based Frequency Analysis are described. The second part serves as a user manual for the super-resolution spectral analysis in the Signal Processing Toolset. The last part describes the application of the theory introduced in the first part, by means of testing the properties of the methods used by the Toolset.

Software for field gamaspectrometr
Adamec, Filip ; Richter, Miloslav (referee) ; Čejka, Miloslav (advisor)
This work is about design, implementation, menu and communication with superior system for gamaspectrometer. The first part of the document describes basic principles of measuring of gamma spectra and their processing. The second part describes in basics software core of the spectrometer, handling of the keyboard, graphic and text output. Used algorithms are described, and their implementation. The third part contains analysis of requirements on menu, basic concepts of menu control. Next, it is described how to handle inputs from user, like numbers, date and time, and also how to solve the menu for display of values and for input of values. The forth part describes requirements for communication with superior system (PC), analyses how to do deal with this and reasons for this solution. The conclusion brings all concepts used in the previous chapters and reached goals.

Project for improving data on clients storage system in relation to anti-money laundering as a branch of risk management in banking
Čejka, Martin ; Švecová, Lenka (advisor) ; Nešetřil, Vlastimil (referee)
Theses in the theoretical part deals with risk management and its concrete form in the banking sector. Closer it is aimed at an area of the implementation of measures against money laundering and terrorist financing (AML). The main task of AML consists in compliance with the legislative framework of the country where the bank operates. In the context of this regulation shall the bank obtain and keep information on a range of clients. The project, which is addressed in practical patr of the theses, is aimed at improving the system of collection and storage of data on clients in co-organization of J&T BANKA. The project is a computerized database application in MS Access, which allows bank staff to work efficiently with information on clients.

ISO 9001 jako nástroj řízení v malých firmách
Čejka, Martin ; Veber, Jaromír (advisor) ; Zámostná, Klára (referee)
Bakalářská práce se věnuje současnému fenomenu zavádění systémů managementu jakosti podle normy ISO 9001 v malých firmách. Cílem práce je posoudit, zda obecná doporučení, která jsou v normativním předpisu obsaženy, jsou způsobylá přinést malým firmám hodnotu. V teoretické části je proveden rozbor požadavků normy. Jsou zde shrnuta pozitiva přístupu i předměty kritiky. V praktické části se práce zabývá specifiky organizování malých firem a jak si tato specifika vyhovují s normativním doporučením ISO 9001. V rámci této části je pro ilustrování tohoto rozboru proveden dotazníkový průzkum mezi cca 50 manažery malých firem. Bylo žjištěno, že ISO 9001 může být vhodným nástrojem pro řízení malých firem. Řada manažerů jej však neumí používat a tak se z nástroje řízení stává spíše administrativní zátěž podniku.
