This diploma thesis deals with the best solution design for a sludge fitting, especially focusing on the right choice of pumps for the waste water treatment plant in Prostějov. The pumps were selected for a circulation pipeline, which heats up the sludge. Several measurements were carried out in order to determine the statistical evaluation of the properties of the pumped medium. The figures gained were used to calculate pressure losses.The diploma thesis is divided into two parts. The first part provides a theoretical analysis of the problem and the second part presents the results and subsequently the reasoning for the new selection of pumps in order to change the WWTP technology from the mesophilic to the thermophilic sludge digestion. The test records describing the testing of the individual samples of the pumped sludge are attached.

The master thesis expresses the opinion on application of the Free Flight concept in European Airspace. In the beginning, the reason and the circumstances for concept application are characterized from both theoretical and practical approach. Afterwards, the key technology elements are defined as well as the ideal approach for developing them. Especially system ASAS was a subject of the deep investigation. Then the system ADS-B is introduced with all related issue from a performance point of view. Finally, the main factors affecting the capacity of the ASAS system in specific area of Airspace are investigated.

The aim of this work is to introduce a new type of fuzzy system AnYa. This system, unlike the classical fuzzy systems Takagi-Sugeno and Mamdani, uses a type of antecendent based on real data distribution. As part of the work there will be mentioned system programmed and its functionality will be verified on testing data.

Title: Photon strength functions in Gd isotopes studied from resonance neutron capture Author: RNDr. Jiří Kroll Department: Intitute of particle and nuclear physics Supervisor: doc. Mgr. Milan Krtička, Ph.D., Intitute of particle and nuclear physics Abstract: Photon strength functions have been studied for more than sixty years. A number of theoretical models was proposed to describe experimental data during that time. However, the correctness of these models is still very questionable and its verification is the subject of very intensive experimental and theoretical activity at present time. In this thesis the analysis of spectra of γ rays following the radiative capture of neutrons on isolated neutron resonances of 152,154−158 Gd nuclei is used to study photon strength functions. Experimental data were measured using segmented DANCE calorimeter that is installed at Los Alamos Neutron Scattering Center in New Mexico, USA. Experimental spectra are then compared with the outputs of Monte Carlo simulation of nuclear elec- tromagnetic decay, performed by DICEBOX code, that is based on the validity of the so-called Extreme Statistical Model. The response of the detector system to generated γ cascades was subsequently calculated using the Geant4 code. An analysis of the data clearly indicates that magnetic...

The γ decay of highly excited nuclear levels can be described within the statistical model of nucleus in terms of the level density and a set of photon strength functions. The knowledge of these quantities enables more accurate calculations of reaction rates in many different reactions which are important especially in nuclear astrophysics and in the development of advanced nuclear reactors. Despite the fact that the photon strength functi- ons have been studied for decades, there are still contradicting experimental results regarding the low energy behavior of dipole strength. One of these ca- ses is the shape of electric dipole photon strength function and the strength of the scissors mode in well-deformed rare-earth nuclei. In this thesis the ana- lyses of γ-ray spectra measured by two different experimental setups are pre- sented. The two-step γ cascades measurements with odd gadolinium targets were performed at the research reactor LVR-15 at the Research Centre Řež. In the multi-step γ cascades experiments the γ rays following resonance ne- utron capture on 161−163 Dy targets were measured with the highly-segmented γ-ray calorimeter Detector for Advanced Neutron Capture Experiments in the Los Alamos Neutron Science Center at Los Alamos National Labora- tory. Experimental spectra were compared...

This thesis is focused on determining the hydromechanical characteristics of clay suspensions, permeability and compressibility, where is the effective stress, the concentration of suspension and is the permeability. Because the compressibility or permeability can't be measured directly, I use Darcian mechanics of two-phase systems to compute the characteristics I wanted from a well- measurable quantities, measured in appropriate experiments. Work has been solved with the support of the project : Hydromechanical characteristics of clay suspensions. The first part deals with a mineralogical characteristics fylosilicates, characterization of kaolin deposits in the Bohemian Massif, physical chemistry of colloidal systems, electric double layers and electro kinetic potential. Experimental section follows later, which proceed from the assumption that the same concentration of kaolin suspension and an identical colloidal state, exposed to the same pressure-temperature conditions, exhibit the same values of hydro mechanical characteristics such as their evolution in time can be described as a continuous function. As the model, I chose the coagulated kaolin suspension. Coagulation are achieved by adding weight percent of solids . Suspension settles in a vertical cylinder of high with an inner diameter of , which...

Results: Due to retrieval process of whole body vibration training it was found out that this method can improve muscle strength, bone mineral density, balance and mobility. The effect depends on chosen parameters of whole-body vibrations. Under certain conditions whole-body vibration training could represent an alternative or a supplement to conventional training in order to increase muscle strength and bone mineral density or improve balance and mobility of elderly. The selection of right vibration parameters could support ordinary physical therapy of some neurological disorders. Keywords: vibration, whole-body vibration...
