Design of a desk coin sorting machine
Uhrová, Simona ; Čípek, Pavel (referee) ; Svoboda, Petr (advisor)
The bachelor thesis demonstrates the design concept of a low cost electromechanically driven coin sorter that can be created by the utilization of additive manufacturing, specifically 3D printing. Technical drawing documentation of the chosen design concept is then provided as well as insight into the 3D printing process. In the conclusion, the working model of the coin sorter is created, and an analysis is offered of potential problematic areas as well as possible improvements and extensions.

Evalution of Fire Rescue Service Responses in Traffic Accidents in the South Moravia Region
Svoboda, Petr ; Kocman, Bronislav (referee) ; Libertín, Josef (advisor)
The dissertation deals with the road accident interventions carried out by Fire fighting units and emphasizes average adjustments as well as the problems of forensic engineering. Within the Southern Moravia region, it analyses the statistical data of the Fire Rescue Brigade of the Czech Republic with relation to the road accident interventions, and it analyses the position of the individual units of the Fire Rescue Brigade of the Southern Moravia in the above system. The dissertation discusses relation between the forensic engineering and the Fire Rescue Brigade of Czech Republic and stresses the possibilities of cooperation.

Foundation of Apartment Building in Třeboň
Jurníček, Lukáš ; Glisníková, Věra (referee) ; Svoboda, Petr (advisor)
The bachelor thesis deals with the theme of the apartment building foundation. Its objective is based on studies of expert resources and static assessment to design an appropriate way of building construction foundation. In the theoretical part of the bachelor thesis, the author is concerned with the most frequent possibilities of establishing common residential house, the area, and underground foundation on deep soils improved. In the second part, the author makes choice of a particular method of foundation (deep while using piles) and applies it to the calculation of the real structure. The static calculation has been described and consequently manually processed, and finally verified within the program GEO 5. The work also includes an overview together with a brief description of other information sources to be used for the creation of static calculation.

Tribological characteristics of smart fluids
Michalec, Michal ; Čermák, Jan (referee) ; Svoboda, Petr (advisor)
The master's thesis deals with experimental study of tribological characteristics of smart fluids. Smart fluids are substances in liquid state reacting to the presence of magnetic or electric field by change in rheological properties. For possible application in devices using conventional lubricants is necessary to choose suitable smart fluid and study the influence of excitation on formation of lubricating layer, friction and wear. Comprehensive description of excitation influence is executed using three experimental devices and theoretical model for measurements parameters specification. Assessed are lubricant film thickness, friction coefficient and wear under smart fluid activation in non-conformal contact. Results show significant observable influence of smart fluids excitation on all assessed aspects. Understanding the mechanisms of smart fluids excitation can be a key step in development of intelligent devices with active external control of lubricant behaviour and character, that could lead to maintenance cost reduction and effectivity improvement.

Load bearing reinforced concrete structure of flat house
Svoboda, Petr ; Krůpa, Pavel (referee) ; Girgle, František (advisor)
The main purpose of thesis is a static solution of load bearing reinforced concrete structure of flat house. The work contains an assessment of waterproof concrete building. The object is built under the groundwater level. Supporting structures are concrete slab, walls and columns. An assessment of these structures is realized in terms of first critical state- carrying capacity and second limit state- limitation of crack widths.
