Design of class-D audio power amplifier
Fiala, Roman ; Götthans, Tomáš (referee) ; Brančík, Lubomír (advisor)
This semestral thesis describes class D low frequency power amplifiers and design of specific 2x100W class D power amplifier. The designed amplifier contains a second order sigma-delta modulator in which the quantization is controlled only by the delay of modulator components. This design does not include the clock generator which usually controls the quantization in sigma-delta modulators. This semestral thesis also includes design of a switched-mode power supply for the power amplifier and for the preamplifier. The PSpice program has been used for the design and verification of some sections of circuits. All designs have been built. Also basic parameters of completed circuits were measured.

Shortwave power amplifier
Fiala, Roman ; Vařacha, František (referee) ; Prokeš, Aleš (advisor)
This master’s thesis describes RF power amplifier design. The designed amplifier has been built. The first three chapters outline basics about radio frequency amplifiers. The basic theory needed for amplifier implementation is also described there. In the fourth chapter the power amplifier is designed. The design is based on the theoretical knowledge. Complete amplifier contains RF preamplifier, power amplifier and filters. The OrCAD PSpice, Ansoft Designer SV and EAGLE programs have been used for the design and verification of some sections of circuits. Measurement results of the built amplifier are in the fifth chapter. This thesis contains also the draft for laboratory exercise.

Design of Deep Fundation of Elderly Care Home in Plzeň
Janočo, Martin ; Fiala, Radek (referee) ; Brdečková, Helena (advisor)
The objective of this bachelor’s thesis is design of pile foundation of a building in specific geological conditions. The design is based on engineering geology report of the area and a scheme of loads on foundations. Calculations are executed in spreadsheet software Excel and in geotechnical software GEO5 – Pile module. Finally, these calculations are compared with Plaxis 2D output.

Design of Gravity Wall in Terms of Flysch Geology
Horňáková, Lenka ; Fiala, Radek (referee) ; Brdečková, Helena (advisor)
The bachelor´s thesis is divided to two main parts, from which first is focused on the theory of reinforced concrete retaining walls. The second, practical part deals with design and assessment of the cantilever breast wall supporting the sloping slope in place of annex of congress hall situated above the northern wall of Tatra´s hotel in Velke Karlovice. The labor contains processing of geomorphology and geology surrounding area, load, sample calculation cantilever breast wall and its assessment.

Impedance measurement with uncertainty assessment
Fiala, Radim ; Zavřel, Jiří (referee) ; Havlíková, Marie (advisor)
This Master’s thesis deals with standard uncertainity determination for electrical quantities measurement. Next, there are proposals of uncertainity calculation procedures for impedance measurement. Impedance is measured by LCR meter Agilent 4263B. Using the proposed procedures, standard uncertainities are then calculated. Furthermore, there is proposal for an improved laboratory exercise for the MEMT subject, implementing the standard measurement uncertainities calculations.

The Abutment Design of the Road Bridge over the Highway D1 by Kurovice
Ponížil, Cyril ; Fiala, Radek (referee) ; Brdečková, Helena (advisor)
The bachelor’s thesis deals with design and assessment of the bridge abutment of the flyover over highway R 55 Skalka – Hulín. This flyover is situated between Tlumacovice and Kurovice. The thesis includes a geological and geomorphological classification of the locality, definition of loads due to bridge constructions, including traffic loads. Design and assessment of two variants (the gravity and cantilever retaining wall) of the bridge abutment are carried out.
