Reconstruction of the road bridge
Laczko, Zoltán ; Krejčík, Vladimír (referee) ; Klusáček, Ladislav (advisor)
The subject of this thesis is to design a new slab structure instead of the steel concrete slab. The structure of the new load bearing structure is post-stressed cast-in-situ slab with continuous slab structure consisting of three spans. The slab is pre-stressed by monostrands. The load bearing structure is evaluated for first and second limit state too. The construction is modeled in software named Scia Engineer 2011.

Ejection mechanism automotive starter pinion
Sláma, Miloslav ; Janda, Marcel (referee) ; Hájek, Vítězslav (advisor)
The thesis describes ways ejection pinions automotive starter and evaluation of the advantages and disadvantages of each solution. The first chapter deals with the principle of operation of DC motors and starters parameters. In the second part, the individual systems are theoretically discussed in terms of design and their advantages and disadvantages. The third part is focused on the most common system, which is analyzed in terms of mechanical and electrical reliability. The last point of the work is to design an experimental analysis Reach starter pinion.

Simulation of circuit breaker maglatch dynamic behaviour
Konšel, Ladislav ; Dostál, Lukáš (referee) ; Valenta, Jiří (advisor)
This work includes the theory of circuit breaker construction and is focused mainly on overload function. It mainly deals with electronic circuit breakers, i.e. equipped with an electronic trip unit. The work is focused on the part of trip unit - maglatch of trip unit. For the purposes of simulation, the geometric model is created. Maxwell program is used for the simulation. The work describes the options for conditions input which are necessary for simulation. Using the distribution of magnetic field intensity and magnetic flux density in the section of trip unit maglatch is determined by the simulation. Furthermore, the force effects acting on the armature of the maglatch are calculated. Force values and the directions acting on the armature are determined by changing the simulation parameters - shift of the armature and coil current. Simulations are performed both for steady-state and for dynamic simulation – movement of armature is taken into account. The supply source for the maglatch is created by an external circuit.

Sheeting of Foundation Pit
Vodáček, Ondřej ; Chalmovský, Juraj (referee) ; Glisníková, Věra (advisor)
First part of the thesis talks about pit sheeting in general, including shafts and trenches as well as pits, however pits are the very main topic and therefore described in details. This part also discusses earth pressure and groundwater issues as applied loads, yet only marginally. Second part demonstrates a particular sheeting structure and its calculation. All presumptions are established here, including double-anchored sheet pile wall geometry, spoken earth pressure loads and groundwater loads plus heavy equipment load during a construction. The calculating process is shown using computer softwares (Plaxis 2D, GEO5) and also in a non-software way using just pen and paper. At the very end of thesis an ultimate limit state (ULS) of sheet piles is assessed, software and non-software results are compared to each other and discussed.

Behavioral economics - how anchor affects demand
PODHOROVÁ, Nikola
My bachelor thesis is focused on behavioral economics. Behavioral economics are based on psychology, sociology and economics. One chapter is dedicated to the psycho-logical direction - behaviorism. I'm interested in the topic: how to anchor affects demand. In my thesis examine the theory in practice, the goal of the experiment is to prove whether people, that they really let anchor to affect them. I called 120 respondents, whose were divided into two groups, each group had its own version of the questionnaire. Each version was equipped with different primary anchor, which causes groups have different results. Both questionnaires contained the same four questions. The data are processed in the STATISTICA program with using ANOVA. Type the questionnaire with which related primary anchor, influenced respondents offered prices. The first questionnaire had the primary anchor wedding ring and a the second one had massage. But it also happened, that some respondents did not offer anything. Naming a star for them are worthless. The issues that included questionnaires, had an impact on the decision-making level of education and the latter type of questionnaire. For other questions failed to demonstrate that they have influences on decision-making.
