Retaining Walls
Michalčák, Jan ; Fiala, Radek (referee) ; Glisníková, Věra (advisor)
This bachelor thesis deals with retaining walls, methods of the design and defects. The thesis then focuses on gebion retaning walls and their defects. The adopted design of the model of gabion for the calculation through final element method (FEM) is here processed and verified. In the practical part findings are applied to a real situation along a cycle path near the village called Tatranská Polianka. The designed retaining wall from gabion baskets is calculated analytically, using the programme GEO5 and PLAXIS 2D. In conclusion, results are evaluated and compared.

Analysis of pile load test
Ponížil, Cyril ; Kotačková, Alena (referee) ; Fiala, Radek (advisor)
There is ussualy used the Masopust's method to assessment the piles in Czech Republic. This method is based on statistical processing of large data set of load piles tests. Due to the using of regression coefficients this method is relatively complicated and not very transparent. Instead, foreign standards ussualy use direct the values of limit stress on the base of piles and unit friction capacity. Procedure for determining the bearing capacity of the piles is thus considerably simplified. In this thesis the Masopust's method is compared with the methods used in Germany and Austria. This comparison provides insight to the safety level that include various approaches.

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.

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.

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.

TACR TJ04000365: Project EDIMO
Chaloupecká, Hana ; Jakubcová, Michala ; Fiala, R. ; Kozohorský, Jan
The report describes the work procedure on the project TACR TJ000365 for the entire duration of its solving. The work procedure, which is already described in the previous reports, is summarized in brief. In contrast, the report is engaged in the validation of the model in deep. The data acquired by the wind-tunnel modelling were utilized for the validation.

TACR TJ04000365: Project EDIMO in the year 2021
Chaloupecká, Hana ; Fiala, Roman ; Jakubcová, Michala ; Kozohorský, Jan
The paper describes methods of work on the project TACR TJ04000365 in the year 2021. The paper focuses on the description of the models SWIFT and SPRAY. Furthermore, the creation of a middle-model, which was necessary to develop as one step from many others to be able to merge both models, is described. Finally, the paper is engaged in the trial-run of the merged models. The paper introduces the input parameters and the outputs in the form of concentration maps. The appendix contains sensitivity study of the model SWIFT in respect to the main inputs.

Investigation of new anode materials for methanol polymer fuel cells
Fiala, Roman ; Matolín, Vladimír (advisor) ; Sofer, Zdeněk (referee)
We investigated new types of anode catalysts for polymer membrane fule cell (PEMFC). Pt doped CeO2 thin lms were deposited by rf-magnetron sputtering on carbon nanotubes (CNTs) directly grown on GDL by using CVD. We observed considerable increase of speci c power by 1000 times and more in comparison with standard PtRu anode catalyst. For this new anode system we obtained the speci c power of 44.3 W/mg(Pt). The interaction of Pt with CeO2 layers with di erent substrates was investigated by using photoelectron spectroscopy. The results showed that platinum was in cationic state and the Pt2+/Pt4+ ratio was dependent of substrates materials. We also demonstrated that the performance of direct methanol fuel cell with Pt and PtRu catalyst can be dramatically increased simply by adding sodium hydroxide to methanol fuel. Cell voltage and power output characteristics were studied in dependence on current, temperature and concentration of sodium hydroxide. Endurance test was performed and the fuel cell exhibited stable response. Power density of 80.7 mW/cm2 was recorded for 2 M methanol/2 M sodium hydroxide fuel 30řC.

Analysis of the requirements for Mobile Monitoring System foe elderly people living in home background
Hrabalová, Klára ; Fiala, Radek (advisor) ; Zeman, Miroslav (referee)
In the thesis the author deals with the Mobile Supervisory System Senior Inspect, which allows monitoring of elderly people living in home background. Monitoring makes use of biological and general technical values, which are wirelessly transported and digestedly displayed in a notebook monitor. The author focuses on the analysis of the requirements, she puts forward the metodology of aplications of the monitoring system. Next the author endeavours to determine the requirements of the monitoring system and extending the whole system. She describes the desk of Senior Inspect 24/7 and checklist created for it. At the conclusion of her thesis the author highlights use of the monitoring system. The findings of this thesis should help when the monitoring system is put into practice.
