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.

Transport of Dangerous Substances in the Czech Republic
VANDAS, David
The topic of the diploma written assignment is "Transport of Dangerous Substances in the Czech Republic" and it was chosen for elaboration of the wholesome view on the road, train, ship and plane transportation of the hazardous materials and mixtures. These transportations represent a possible risk of damage to life, health, property or environment for the society. Hazardous materials and mixtures nowadays are being transported in large measures and there is an assumption in the future that the volume of the transported hazardous materials and mixtures will increase. For elaboration of this written assignment three hypothesis were given: a) Legal regulations of the European Union and the Czech Republic solve the problematic of the transportation of hazardous materials and mixtures well enough. b) The public has enough information about the transportation of the hazardous chemical substances or mixtures. c) People that work in the field of the transportation of hazardous materials or mixtures are well informed about the transportation of hazardous chemical substances or mixtures. For determining whether the legal regulations solve the problematic of the transportation of hazardous materials and mixtures well enough the literary sources which deal with this issue, legal regulations of the Czech Republic and the European Union and other international agreements were used. After working through these sources it was found out that the international, the EU and Czech legal regulations or agreements solve this issue well enough and emphasis is given on convergence of legal regulations of all transportations. Implementation of international agreements and legal regulations of the European Union into the legal regulations of the Czech Republic happens in the present time very fast and without failures. For figuring out the awareness of the public and awareness of the people working in the field of the transportation of hazardous materials and mixtures for the diploma written assignment on the topic of "The Transportation of Hazardous Materials and Mixtures on the Territory of the Czech Republic" there was a quantitative research made. The quantitative research was made with the help of handed out questionnaires. The public was represented by the employees of the Regional Municipalities of the Czech Republic. Both of the groups were given the same questionnaires. The results of the questionnaire research were evaluated, expressed in percentage and statistically assessed. For the statistical assessment the double selection T-test was used to find out whether the difference between the assessed groups is statistically important. People working in the transportation of hazardous substances and mixtures have sufficient information which was confirmed by the questionnaire research. By the made statistical assessment it was found out that the difference between the groups is statistically significant and so the public does not have sufficient information related to the transportation of hazardous substances and mixtures. Due to the results of the questionnaire research and mainly that the hypothesis b) - The public has enough information about the transportation of hazardous chemical substances or mixtures was not confirmed. In the conclusion of the written assignment there are a couple of suggestions for improvement of the awareness of the public. For example as a part of education at primary and high schools and training schools where this education is already running as a part of The Protection of Human during Incidents. This education has been going on since 2003. And that is why the older people in the public are not well met with this issue and they should be introduced to it by for example a media campaign by means of short TV spots on public television channels or by means of spots that already the Independent BESIP Department of the Ministry of Transportation makes up. These spots are called Besipky.

Potential of IoT in Smart City
Pavlíček, Tomáš ; Gála, Libor (advisor) ; Basl, Josef (referee)
The aim of this masters thesis is to identify, in which phase of adoption of Internet of Things (IoT) application areas of concept Smart City are nowadays Czech regional cities, what is their outlook to 2025 and also identify in which dimensions of concept Smart city, supported by IoT technologies, perceive Czech regional cities the greatest potential. Based on information obtained from the studied materials, the concept of Internet of Things (IoT) is described, along with a detailed description of one of its application area, namely Smart City. This area is further divided into specific dimensions, that cover specific application areas which can, through internet technology, support things in a special way. With these insights, the questionnaire (built on identified IoT application areas of smart city) was developed. Thesis should be beneficial for all towns in the Czech Republic, because it provides a comprehensive view of individual IoT application areas of concept Smart City including information on which of these IoT application areas are currently focusing regional cities, and on which they want to focus to the future. On the other hand, the survey results could also be beneficial for commercial entities, which focus on IoT implementation in cities. These entities will be able to recognise which IoT products are currently best for cities.

Carbon nanotubes are exceptional nano-objects with respect to their remarkable properties, holding great potential in new polymeric materials design with unique characteristics. To illustrate it, the conventional glass reinforced epoxy composite is combined with a layer of entangled network of carbon nanotubes deposited on polyurethane non-woven membrane. The prepared nano-composite is studied for their diverse mjulti-functional applications involving extension and compression strain sensing composite, remoulding by means of resistance Joule heating and radiating as a planar micro strip antenna operating at frequencies of 2MHz up to 4GHz.

STRAIN ENGINEERING OF THE ELECTRONIC STRUCTURE OF 2D MATERIALS
del Corro, Elena ; Peňa-Alvarez, M. ; Morales-García, A. ; Bouša, Milan ; Řáhová, Jaroslava ; Kavan, Ladislav ; Kalbáč, Martin ; Frank, Otakar
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
