Advanced signal processing in composite material properties investigation
Blaháček, Michal ; Landa, Michal ; Zídek, Jan
Composite material parameters evaluation depends on our ability to simplify complex wave field. Fractional wave mode arrival usually evokes transient effects in the measured signal. In the paper new method of transient effects detection is discussed. The method is efficient tool for fractional wave mode detection and wave arrival time computation.

Evaluation and motivation in public administration
Vašíčková, Natálie ; Mitwallyová, Helena (advisor) ; Vláčil, Jan (referee)
The theme of the bachelor thesis is the evaluation and motivation of employees in public administration. The introductory part outlines the evaluation and motivation of employees on a general level, and then describes the specifics applicable for public administration. The practical part is focused on the evaluation and motivation systems used at selected institutions of public administration. It aims to assess these systems, suggest possible recommendations and find out whether the systems in use include modern management methods, such as evaluation interviews, competency models and regular system of employee evaluation as such. The research method consisted of interviews with human resources managers at selected institutions of public administration. Complementary information was obtained from materials created by these institutions themselves. All institutions of public administration are governed by Act No. 234/2014 Coll. on Civil Service, enshrining the evaluation of state employees. However, it depends on whether employees are evaluated formally, or if additional evaluation tools beyond the framework of the law are deployed, e.g. competency models. Officials of territorial authorities are subject to Act No. 312/2002 Coll., which does not explicitly define employee evaluation, yet employees are evaluated at many regional as well as local administration units. The results of the research survey confirmed that modern management methods are used in public administration and that the evaluation systems do not have any significant shortcomings.

Task collection for students trained to be teachers at primary school and also for teachers in profession is part of my thesis.

Specifics of nursing care of a child patiens with oncological pain.
ČAŇKOVÁ, Helena
The topic of the thesis is: Specifics of nursing care of a child patient with oncologic pain. Children{\crq}s pain is a phenomenon surrounded by many myths and false information. It is also not sufficiently assessed and treated and often bagatelized by both nurses and doctors. Nurses play irreplaceable role in pain treatment, they are with the child patient more frequently then the doctor and are in close touch with the child{\crq}s parents. The care of a suffering child is a serious task in nursing. Treatment of a patient in pains requires a complex, holistic approach. Nurses, even if they diagnose pain properly, do not set an adequate nursing care plan and do not carry it out. Nurses have to defend interests of the sick child and must not let him/her suffer. The data was obtained by quantitative and qualitative research. The quantitative research was carried out by the technique of anonymous questionnaire. The questionnaire was made for the parents of children with oncologic disease. The qualitative research was carried out by the technique of semi-structured in-depth interview. The research sample consisted of nurses working at the Department of children{\crq}s oncology One of the aims of this thesis was to outline the problems in nursing care of a child patient with oncologic pain from the point of view of the parents. We observed if the parents had been informed about their child{\crq}s pain, if they know what symptoms they should watch in their child, if they know all the aspects of pain to be assessed and treatment methods to relieve the pain and also how nurses respond to their child{\crq}s pain. For this aim, a following hypothesis has been set forth: The parents of children patients with oncologic pain are educated about the possibilities of nursing care focused on relieving the pain. This hypothesis was confirmed by statistic testing. Another aim of this thesis was to find out the specifics of nursing care of a child patient with oncologic pain. Nurses think that the specifics of nursing care of a child patient with oncologic pain are not different from any other care of a child in pains. They just state that an oncologic disease is associated with pains caused by the disease itself or by diagnostic or therapeutic procedures. Therefore they consider a specific feature the fact that the pain is observed more intensively and the staff is more precise in relieving the pain. It is obvious from the research that it would be effective for both parties, both for the nurses and the parents, to use educational materials on pain intended for them. I suppose that if there were such materials available, the parents would not need to contact nurses repeatedly. There was also a positive finding in the research that 92.5% of parents stated that nurses respond to children{\crq}s pain within 10 minutes. Further, that nurses believe that the child has pains, which was stated by 98.2% of the parents.

INFLUENCE OF LASER CUTTING AND PUNCHING ON MAGNETIC PROPERTIES\nOF ELECTRICAL STEEL M470-50A
Bulín, Tomáš ; Švábenská, Eva ; Hapla, Miroslav ; Ondrůšek, Č. ; Schneeweiss, Oldřich
Electrical steel M470-50A belongs to the most often used materials in electrical machines. Due to this fact, it is desirable to know the magnetic parameters after processing raw sheets into the required shape. Basic parameters of mechanical, electrical, and magnetic properties of the sheets are usually obtained from the producer but the magnetic properties are changing in dependence on additional machining processes. The aim of this study is to describe changes in parameters of magnetic behavior after punching, laser and spark cutting of the original sheets. The basic information of structure was obtained by optical and scanning electron microscopy. The magnetic parameters were acquired from the measuring of magnetic hysteresis loops in dependence on saturation fields and frequencies. The results are discussed from the point of view of applied\ncutting technology with the aim to obtain the best magnetic parameters and consequently a higher efficiency of the final product. Results can be used as input parameters in simulation of the electrical machine.

The research on graphene has attracted much attention since its first successful preparation in 2004. It possesses many unique properties, such as an extreme stiffness and strength, high electron mobility, ballistic transport even at room temperature, superior thermal conductivity and many others. The affection for graphene was followed swiftly by a keen interest in other two dimensional materials like transition metal dichalcogenides. As has been predicted and in part proven experimentally, the electronic properties of these materials can be modified by various means. The most common ones include covalent or non-covalent chemistry, electrochemical, gate or atomic doping, or quantum confinement. None of these methods has proven universal enough in terms of the devices' characteristics or scalability. However, another approach is known mechanical strain/stress, but experiments in that direction are scarce, in spite of their high promises.\nThe primary challenge consists in the understanding of the mechanical properties of 2D materials and in the ability to quantify the lattice deformation. Several techniques can be then used to apply strain to the specimens and thus to induce changes in their electronic structure. We will review their basic concepts and some of the examples so far documented experimentally and/or theoretically.

ELECTRON BEAM REMELTING OF PLASMA SPRAYED ALUMINA COATINGS
Matějíček, Jiří ; Veverka, J. ; Čížek, J. ; Kouřil, J.
Plasma sprayed alumina coatings find numerous applications in various fields, where they enhance the properties of the base material. Examples include thermal barriers, wear resistance, electrical insulation, and diffusion and corrosion barriers. A typical structure of plasma sprayed coatings, containing a multitude of voids and imperfectly bonded interfaces, gives them unique properties - particularly low thermal conductivity, high strain tolerance, etc. However, for certain applications such as permeation barriers or wear resistance, these voids may be detrimental.\nThis paper reports on the first experiments with remelting of plasma sprayed alumina coatings by electron beam technology, with the purpose of densifying the coatings and thereby eliminating the voids. Throughout the study, several parameters of the e-beam device were varied - beam current, traverse velocity and number of passes. The treated coatings were observed by light and electron microscopy and the thickness, structure and surface morphology of the remelted layer were determined and correlated with the process parameters. Based on the first series of experiments, the e-beam settings leading to dense and smooth remelted layer of sufficient thickness were obtained. In this layer, a change of phase composition and a marked increase in hardness were observed.\n

Black Chromia Coatings on Metal Tubes for the Solar Collectors
Brožek, V. ; Mastný, L. ; Novák, M. ; Vilémová, Monika ; Kubatík, Tomáš František
This paper describes the results of the first phase of the study preparation, structure and properties of coatings modification of black chromium oxide on copper, aluminium, iron and zirconium tubes for solar collectors. The coatings are prepared by plasma spraying of liquid chromate method which is known as liquid precursor plasma spraying. Coatings have the function of an energy trap for thermal radiation wavelengths of 1 μm – 3 μm i.e. in the IR region. At the same time, the coating increases the corrosion resistance of metal substrates. The nanometric structure and thickness of the coating depend of the feeding distance and the concentration of chromate precursors. For the deposition of nanometric splats of melt chromiumIII oxide, a new type of feeder that injects precursors into the water stabilized thermal plasma produced by the WSP® generator has been\ndeveloped.\n

NUMERICAL SUPPORT FOR SPECIMEN LOADED BY BENDING AND WEDGE SPLITTING FORCES FOR MEASUREMENT OF CONCRETE PROPERTIES
Seitl, Stanislav ; Liedo, R. ; Holušová, T.
Fracture mechanical properties of silicate based materials are performed from various fracture mechanicals tests. For evaluation of parameters, the knowledge about calibration and compliance function is so important. Therefore, in contribution the compliance and calibration curves for a novel test based on combination wedge splitting test (WST) and three-point bend test (3PBT) are introduced. These selected variants exhibit significantly various stress state conditions at the crack tip, or, more generally, in the whole specimen ligament.
