Experimental determination of the hydrodynamic load of the flooded bridge model
Naiser, Dominik ; Hrdlička, Libor (referee) ; Zubík, Pavel (advisor)
The diploma thesis deals with experimental determination of hydrodynamic load on the overflowed bridge deck model. In the first part of the thesis the author describes the analysis of the problem together with the basic physical laws and principles that are used or assumed in the measurement itself. In the second part the author describes the measurements in the laboratory of the Faculty of Civil Engineering and its gradual processing. At the end of the work are described the results of measurement, their comparison with numerical modeling, other authors and their possible use in practice.

Deficiencies and inaccuracies in measurement of MV distribution network laboratory model
Němec, Jiří ; Vyčítal, Václav (referee) ; Ptáček, Michal (advisor)
The paper analyzes the deficiencies and inaccuracies in measurement of medium voltage distribution network laboratory model. The aim is to propose solution to these problems. In the second chapter, basics of the theory of medium voltage network and the operating parameters of distribution grids are described. The theoretical part is mainly based on the Czech technical standards. The third chapter focuses on description of the laboratory model and it contains its label values. The fourth chapter deals with executed measurements and mathematical models created in the program PSCad. Comparison of the measurements and the computer simulations is included. Description of the measurements contains its purpose, the measured parameters and results of the measurements. Input parameters for creating computer simulations are listed and their results are processed. In response to measurements, yet unknown parameters of the laboratory model and its behavior in various operational states are clarified. On the basis of the findings, which this paper brings, it is possible to modify the laboratory exercise and thus reach more accurate results.

Internet based control of laboratory models
Dobrovolný, Petr ; Smrčka, František (referee) ; Zezulka, František (advisor)
This award solves design of two models that are designed to teach on PLC and in the future on the Control Web. Both models should be used in LabLink system, which allows you to remotely working on laboratory tasks. The first software model simulates the movement of trains on rail in relation on control from the PLC. The second model is a physical model of drill. In both models are solid managing and type of construction, which allows operation without physical intervention.

Evaluation of hydrodinamic load on a brdge deck
Řezník, Jindřich ; Dráb, Aleš (referee) ; Špano, Miroslav (advisor)
The subject of this thesis is the evaluation of hydrodinamic load on a physical model of a bridge deck, especially to find the relation between the median and extreme quantiles of each hydrodanamic load part and to evaluate the influence, which has the shape of the bridge deck on the size of this load. Relations, that was found may be used to determine characteristic values of loads, caused by water flow, for example, when designing the bridge bearings.

Design of the container manipulator laboratory model
Kolacia, Kryštof ; Malášek, Jiří (referee) ; Pokorný, Prokop (advisor)
This thesis deals with the design of a container manipulator laboratory model for a 1:20 scale transport unit and a carrying capacity of 60 kg. The thesis is divided into theoretical and computational part. Firstly, the design solutions are examined in practice. Subsequently, control calculations of important parts of the proposed structure as well as of the twist locks are made. An economic analysis is then elaborated. In conclusion, the drawing documentation of the spreader design and selected components is attached.

Experimental Infection of Mice and Ticks with the Human Isolate of Anaplasma phagocytophilum NY-18
KALINOVÁ, Eliška
Anaplasma phagocytophilum is a significant tick-borne pathogen that colonizes granulocytic cells in vertebrate hosts. It is found in North America and in several European countries. It causes severe diseases in domestic animals and potentially fatal disease in humans called human granulocytic anaplasmosis (HGA). The implementation of animal models is necessary due to the increasing prevalence of A. phagocytophilum. This study addresses the transmission of the human isolate of the bacterium A. phagocytophilum NY-18 by two tick species (Ixodes ricinus and Ixodes scapularis) and implements a laboratory model for the transmission of A. phagocytophilum by the tick I. ricinus in mice. The thesis also compares both transmissions and infection dynamics.
