Forms of Business Risk Protection of Construction Work
Štaffa, Jan ; Witala,, Lukáš (referee) ; Korytárová, Jana (advisor)
This master’s thesis is focused on the business risk protection in construction projects. The first part is dedicated to an interpretation of theoretical knowledge which defines and describes the risk, acquaints readers with principles of the risk management and presents commonly used forms of the business risk protection in practice. The second part deals with a practical use of the protection tools and proposes their effective adjustment in the selected public works contracts.

DC/AC inverter with digital control
Štaffa, Jan ; Pazdera, Ivo (referee) ; Minárik, Vladimír (advisor)
This work is focused on single phase inverters, which are used for the conversion of the direct current to the alternating current and are nowdays used especially in systems of back-up power supply. The specific aim of this work is implementation of design hight power circuit of inverter include calculation of control algorithm. It describes the complete solution of power circuit. Next step is a analysis of problems concerning the digital control with help of signal processor which is used for solution of regulator structure. Check of the design and checkout of control algorithm is made in the form of simulation in the MATLAB Simulink. Debugged program algorithm is subsequently implemented into the signal microprocessor. The work results rate estimation functionality of inverter and solution of control algorithm.

Medium voltage substation automation using control system COM600 and standard IEC61850
Havelka, Tomáš ; Štaffa, Jan (referee) ; Háze, Jiří (advisor)
This work deals with problematic of standard IEC61850, mainly with chapter IEC 61850-9-2 LE which is commonly known as Process bus communication. There are described advanced tools of the control system COM600 with detail description of their configuration in this work. It also deals with configuration of IEC 61850-9-2 LE with Relion family protection relays and its implementation to the control system COM600. The main aim of this work is focused on configuration of IEC 61850-9-2 standard with protection relays, configuration and detail description of COM600 advanced tools, description of Logic processor, further custom design and appliaction configuration global reset of Logic procesor in control system COM600.

Qualifications for Public Works Contracts
Štaffa, Jan ; Witala,, Lukáš (referee) ; Korytárová, Jana (advisor)
This bachelor’s thesis is focused on issue of the qualifying requirements for the public works contracts. The first part contains basic notions of the public procurement and describes the various qualifying criteria. The second part deals with practical use the qualifying requirements. The aim of this thesis is the analysis frequency occurrences of qualifying criteria and develop detailed statistics their real application in the South Moravia Region in 2011.
