Design of shallow foundation using Penetration tests
Bastl, Jiří ; Fiala, Radek (referee) ; Štefaňák, Jan (advisor)
The bachelor´s thesis focuses on the principle and implementation of penetration tests and search procedures using the test results of penetration test for design of shallow foundations. The purpose of this work is to compare the design of sallow foundations using conventional methods and computational methods based on the use of penetration tests. In the project TA04031092 – interpretation and correlation of dynamic and static penetration test, I worked with data on which I assembled and tested correlations between cohesion of clays and penetration resistance for the region and around Brno.

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.

The Study During the Engagement in the Manufacturing Company
Kubíček, Filip ; Fiala, René (referee) ; Jurová, Marie (advisor)
This master thesis is aimed at optimalization of chosen processes of manufacture of the company DH DEKOR Spol. s r.o. which is engaged in production of impregnated paper and laminated boards. On the basis of the results of processes in storehouse and manufacture of impregnated paper there are given proposals and possible measurments whitch leads to minimalization of time and financal losses.

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.

Waterpark Jeseník - selected geotechnical problems
Kučera, Jakub ; Fiala, Radek (referee) ; Glisníková, Věra (advisor)
The bachelor thesis discusses the possible ways of establishing the basics of structures. Its main focus lays on foundation pads and piles. The practical part consists of finding a solution regarding two different approaches of the foundation of the waterslide in Aquapark Jeseník. Even though the proposed variants are calculated without the use of computational software, software GEO 5 is used to compare the results. The conclusion contains the comparison and evaluation of the results of both approaches.
