These thesis brings new findings in flood issues, which importance has been sharply increasing in the light of last years experience. Hypotheses about the usefulness of hydrological measurements in the creation of computational geometry watercourses, as well as using the data from aerial laser scanning in the preparation of computer tracks water flows have been confirmed. Presented papers introduce the use of new technologies, knowledge and other results of applied research in the field of preparation of input data for hydrodynamic models, geographic information systems, personal identification and early warning and information sharing to support the elimination of consequences of natural disasters or traffic accidents. The above presented findings about the use of airborne laser scanning data and synthesis these data with hydrological measurements are of great importance for the improvement of flood prevention. Another practical use of these findings lies in urbanism planning and flood forecasts. The effort is to increase the security of citizens in the case of threats to their security through early warning - ie. Preventative protection by results of conducted research in the field of mathematical modelling rainfall-runoff and passage of flood flows in the river system providing new knowledge for the identification and registration of persons. During the research conducted, the attention was paid to define tools supporting integrated activities of the state security and rescue forces, including increased education and communication between state administration, local governments and the public. However the main goal of this work is to prevent the effects of natural and anthropogenic risks to human health and property of citizens. The attention is paid especially on the most common natural hazard represented by the floods.

The use of only one primary sort of energy is the present trend of aircraft design and its force systens. There are designed electromagnetical force systems for control of ther moving parts of aircraft structure. Great demands are laid on energy and dynamic characteristics at some force systems, especially at aircraft control system, and therefore there are developed electro-hydrostatic actuators, suitable for aircraft for aircraft control system, which could graduallly replace commonly used hydraulic servo-controol system. Not only electric signals but also required electric outputs are led into these electro-hydraulic actuators. Using a hydrostatic converter it is changed into mechanical output controlling the aircraft control system. The goal of work is to set requirements for characteristic and conception of electro – hydrostatic actuators for aircraft control systems. Further, on the basis of theoretical analysis , computer modeling and experiment, the design optimisation of electro-ghydrostatic actuator should be done for small business aircraft from the point of view of dimmensions and dynamic characteristics.

In the literary part of the diploma thesis, a brief overview of the current state in the tractor design has been done, concentrating onto such elements that lead to lowering of fuel consumption. The practical part is based on the realized solution. The target of the measurement was to prove the influence of adjusting of the three-point hitch onto the output parameters of ploughing sets, consisting of the Zetor Forterra 140 HSX tractor and Kverneland 150 B mounted plough or Kverneland PN 100 semi-mounted plough. The essence of the measurement was gradual shortening of the upper linkage of the three-point hitch, whereas simultaneously with shortening of the linkage, the force on the linkage was rising. The force was measured by means of strain gauge Hotinger U2A. In case of the mounted plough it has been proved that shortening of the upper linkage causes rising of the force. That shifts part of the plough weight onto the rear wheels of the tractor, resulting in lower wheel slipping and lower fuel consumption.

The subject of this thesis is realization of short research of current compact hydraulic power unit, realization of FEM analysis with aim to find inappropriately dimensioned parts of structures. Based on this data design optimized solution of structures and create drawings of weldments. This thesis is carried out in cooperation with company Bosch Rexroth, spol.s.r.o.

The assignment of my diploma thesis is to design the family house heating system. The source of energy is heat pump for heating which takes heat from areal collector.

This master’s thesis deals with design of a hydraulics bending machine. Bending machine will be used primarily for bending reinforcement bars in the shape of stapes. It consists of bending, sliding and chute system, which are located in the machine frame. Drive of each system is provided by a rotary and two linear hydraulic motors. Then there is described a hydraulic system and selection of its most important parts. Work is supplemented by visual documentation in the form of images of individual systems were processed in a CAD system Inventor 2010

This thesis deals with construction of higher output tractors. The theoretic part is di-vided into three main parts. The first part of this thesis is about emissions of internal combustion engine and element of construction as are compression ignition engine and Common rail fuel injection. The second part is about constructions of undercarriage primarily about front axle of tractor. The last part deals with tractor hydraulic system and its control systems. The practical part of this thesis is about John Deere 8320 R. All measurements have been provided in agriculture operations with machines of Köckerling and Lemken in Zeas Polešovice a. s. The field measurements are divided into two parts of engine work. In the first part of work, the engine has the revolution 1500-1800 min-1, in the second part of work, the engine has the revolution 1800-2100 min-1. Fuel Consumption, total time, revolution, time for rotation, width and depth of the harrow were included. The measured values were calculated effective fuel consumption, opera-tional consumption, efficient performance, operational efficiency and working speed trains.

This diploma thesis deals with the creation of models simulating the processes of an emission-free wheel loader, which was created by rebuilding the original version with a combustion engine. Part of the work is the methodical creation of models from the basic part of the machine to a simplified model of the overall machine, its functional verification and calibration based on available information’s and measurements. In this paper, selected parameters of the overall machine model are verified based on performed measurements, the suitability of selected components is verified, and the optimization and modification of the model is performed based on verification. The aim of the thesis is to present the simulation and verification procedure and its practical use in the development of an emission-free wheel loader with electric drive.

The subject of this thesis is design and strength analysis of stationary hydraulic device. Strength analysis is made by the finite element method. The thesis describes design of used frames, profiles and other components, which are parts of the frame. Frame modification is proposed, based on the results of the strength analysis. These modifications are checked with strength analysis. The thesis includes drawing of weldment. The project has been carried out in cooperation with Bosch Rexroth, spol. s. r. o.
