Computational analysis of working roll surface layers in hot rolling
Luks, Tomáš ; Hajduk,, Daniel (referee) ; Pohanka, Michal (advisor)
This thesis is dealing with an analysis of thermal and mechanical loads on a work-roll. First, hot rolling focused on work-roll is described in general. A theoretical analysis of roll loads and the mechanisms affecting roll durability are presented here. The thesis is concentrated on creation of a model in FEM program ANSYS. The final model is loaded with different rolling schemes and monitored stresses in a surface layer. The parameters obtained from the measurements performed in a rolling mill are applied as boundary conditions within the model.

Complex Permittivity Measurement of Biological Tissue
Vorlíček, Jaroslav ; Hozman, Jiří (referee) ; Oppl, Ladislav (advisor)
This thesis deals with the measurement of complex permittivity of biological tissue as the default precondition for the design of thermo-therapeutic microwave applicators for hyperthermia oncology treatment, when for the valid simulations of electromagnetic field is necessary to know the dielectric parameters of the environment. There are described different approaches to measure complex permittivity, in particular the non-invasive method of measuring complex permittivity at the end of the coaxial cable. For this purpose two measuring probes have been designed, constructed and tested. The first one based on N-connector and the second based on the SMA-connector. Simulations of the probe's models were simulated in program SEMCAD 14 and double checked by CST MICROWAVE STUDIO 2009. The possibilities of measuring complex permittivity of biological tissue as a potential diagnostic imaging method are also discussed. Measurements in order to demonstrate the diagnostic potential of this method were first conducted on artificially created non-homogeneous agar phantom with added mixture of various dielectrics, followed by measurement of biological tissue in vivo.

Nursing care in a hygienic and epidemiological regime from the patient's perspective.
KŘEPELOVÁ, Lenka
Considering contemporary lifestyle and possibility of travelling imported infections accrued and some illnesses come back that have not occurred nearly at us more. Not only haemorrhagic fevers and other highly infectious illnesses but also hospital multiresistant bacterial strains that mean high risk for patients constitute a threat. The number of nosocomial infectious grows still. The patient is in the case of suspicion or already diagnosed infectious illness isolated and treated in the infectious department or in the tribal department in the room with increased hygienic-epidemiologic regime. The patient is saved in a single room, the possibility of visits is reduced and the staff uses personal protective equipment. The man is holistic being and it can come due to isolation to lack of satisfaction of his/her bio-psycho-social needs. The aim of this thesis is to identify unsatisfied bio-psycho-social needs of patients in increased hygienic-epidemiologic regime and to describe changes in needs of the patient depending on the time of hospitalisation. The theoretic part describes the problematics of infectious illnesses, system of the care for the patient with infectious illness and changes in human needs in the period of the illness. The empiric part of the thesis deals with unsatisfied bio-psycho-social needs of isolated individual through quantitative research. The research suite was made up of 10 patients who were hospitalised in the room with increased hygienic-epidemiologic regime. The survey was carried out in the Hospital Jihlava by semistructured interview and the results of the survey were processed by opened coding by method paper and pencil. It is emphasized that the most needs of the patient have biological, psychical, social and even spiritual aspects. The rate of satisfaction with caregiving depends on the health condition and personality of the patient. Not small influence has the length of the hospitalisation, too. It was found out during the survey that the patients have not enough information about specifics of the care in the infectious department and that is why there is often a misunderstanding of necessity of barrier measures. It is possible to avoid useless misunderstanding through timely and suitable education. It was created an educational material with the title "Guide for patients hospitalised in the infectious department of Hospital Jihlava" for this purpose. Employees of the infectious department of Hospital Jihlava were informed with results of the research during a workshop, too.

Measurement of the velocity distribution in a low-velocity outlet jet
Uhlář, Václav ; Pavelek, Milan (referee) ; Janotková, Eva (advisor)
Diploma thesis deal with measuring air-jet generated by low-velocity outlet. Diploma thesis piles of several part. First part includes velocity measurment (flow volumes) single ventilators. Follows measuring velocity distribution in air-jet generated by low-velocity outlet, his vizualization by the smoke method. Last point is problems errors and uncertainties measuring. Thesis likewise includes appendices, where there are mentioned tables from single maesuring and setting frequency transducers.

Evaluation of selected municipalities management
Faustenová, Kateřina ; Homolka, Jaroslav (advisor)
This thesis deals with the issue of selected municipalities management. The theoretical part explains the issue of municipalities financing and their budgets. Furthermore, the basic characteristics of selected municipalities is presented, therefore of the municipality Svojetice and the municipality Struhařov, both lying in the district of Prague-east, approximately 30 km from the Capital city of Prague. In the practical part of the work is evaluated and compared management of both municipalities in the reporting period 2010 - 2015 and their overall financial situation. Through the own research there is also evaluated and compared the level of development of municipalities depending on their management. In conclusion are summarized the most important results and knowledge arising from the research and are designed measures contributing to the improvement and streamlining of management in the following years.

Problems of a limit fatigue stress under combined loading
Balda, Miroslav ; Svoboda, Jaroslav
The theory of fatigue life of structures under combined synchronized harmonic loading has been extended. Limit stress of combined loadding corresponding the fatigue limits has been assembtet from experimental data. They obey both the law of ellipse for in-phaseloading and a bit modified law for out-of-phase loading. A new formula for its exponent has been built.

High-Frequency Pulsations Modeling
Střecha, Ludvík ; Kubálek, Jiří (referee) ; Habán, Vladimír (advisor)
The diploma thesis deals with the mathematical modeling of high-frequency pressure pulsations in water turbines. Pulsations are caused by the interaction between stator a rotor blades. These high-frequency pressure pulsations then cause high cycle fatigue of the head cover, spiral casing, runner and distributor. The mathematical model is solved by transfer matrix method. Data are processed in F-A char and MS Excel programs. Final results are demonstrated by frequency amplitude characteristics and by pressure mode shapes, where comparison of the mathematical model with the measurement is shown.

Problematics abandoned and old mining works in relation to possibilities of stability solution on Jeroným mine example
Kukutsch, Radovan
This paper appears from dissertation work themed „Problems of selected technical and economical aspects of mines technical liquidation in ore and coal mining conditions". Arcticle deals with aspects of old and abandoned mining works, which in the long term represent a controversial issue of mines technical liquidation process. The Jeronym Mine was selected as a sample locality of old and abandoned mine, on which the author presents and interprets the survey approaches and discusses the future and problems related to accesing of this unique mining work.
