The Roof Structure of a Multipurpose Sport Building
Malchárek, Robert ; Barnat, Jan (referee) ; Buchta, Stanislav (advisor)
The subject of the Diploma thesis is a design wooden structures of a multipurpose sport building in Šumperk. The floor plan measurements of the building are 45,0 x 48,0 m with the maximum height 15,0 m. The solution is choosen on the basis of two variants. The structures is designed with respect to ultimate and serviceability limit states. The multipurpose sport building is consist of 13 main truss centre to centre spacing 4,0m. The main structural system is design as the three-hinged arched structure made of solid timber and in the second variant as the arched structure made of glue laminated timber. The spatial rigidity of the structure is secured of diagonal bracing. The roofing is carried by rafter which are safed by purlin and then by upper chord. The steel columns are design as a part of gable wall. The project was carried out in the scia Engineer 2014 software. Some of the particular elements both variants were checked and designed by manualy calculating. The thesis includes structural design report, joints structures, drawings and production drawing the element of the three-hinged arched structure.

The Use of Franchising in the System Providing Health Care Services in the Czech Republic
Pleva, Miroslav ; Lešetický, Ondřej (advisor) ; Mlčák, Jan (referee)
This thesis deals with the usage possibilities of franchising within the scope of health care services provided in the Czech Republic. First part of the thesis concerns franchising in general, describes its principals, development, law regulation etc. Second part analyzes franchising market in the Czech Republic and subsequently identifies respective concepts that are active within the scope of health care services. In my opinion, based on the analysis performed and with respect to theoretical findings, due to specifics of health care services, franchising might represent a suitable form of cooperation only among selected types of these services. Recommended among the concepts available on our market within the scope of health care services are those, which according to my opinion have potential to become a successful business opportunity.

Dark Web: Black market on the internet and its impact on the Czech national economy in the years 2011-2015
Nedvědová, Barbora ; Štípek, Vladimír (advisor) ; Klement, Josef (referee)
The main goal of this thesis is to analyse the influence of the Dark Web on the national economy of the Czech Republic between the years 2012 and 2014. The term 'the Dark Web' and basic elements, which are related to the internet black market, are analysed in the theoretical part of the thesis. The practical part of the thesis contains the estimation of the impact of the Dark Web on the national economy, particularly on national accounts, and other macroeconomic indicators such as GDP, tax colletion, the size of the grey market and the black market, employment and exchange rates. The estimation is based on the available data from both the Czech Republic and abroad. Time periods, in which the mentioned macroeconomic indicators from the Czech Republic are affected, are determined at end of the thesis. By using available data, it is possible to prove the influence of the Dark Web on the Czech national economy and on the mentioned macroeconomic indicators. For example, in 2014, the Dark Web accounted for less than 9 per mille of the GDP of the Czech Republic. Another conclusion is that the Dark Web contributed less than 0,1 % to the grey economy, and less than 2 % to the illegal economy. The internet black market accounted for nearly 8 per mille of the revenue of social security and health insurance.

The Segregation in Ferrous Alloys when Casting Heavy Castings
Pernica, Vítězslav ; Čech, Jan (referee) ; Vodárek, Vlastimil (referee) ; Havlíček,, František (referee) ; Šenberger, Jaroslav (advisor)
This thesis is dedicated to the field of manufacture of heavy steel castings with resulting properties which are influenced by long solidification time. During the long solidification time a segregation process of additives in the steel occurs which results in numerous metallurgical defects. The work was intended to observe the macrosegregation effects in the wall of a heavy experimental steel casting respectively a part of a real superheavy casting intended for cement furnaces (weight 210 t). The steel casting for the research was manufactured in the joint-stock company of VHM where such heavy castings are commonly produced for the market. The supplied piece of the steel casting was cut into the smaller pieces for the better examination. The examination resulted in information about the casting macrostructure and chemical heterogeneity of chosen elements in the casting wall. The heterogeneity of the chosen elements (C, Mn, Si, Cr, S, P) is clearly shown in the worked out visual concentration maps. Based on the experimental data the measured results of segregations were confronted with the results of segregation modelling with the use of the commercial simulation software ProCAST. It resulted in the conclusion that the prediction of segregations is not in accordance with the reality. Furthermore, the results from the experimental casting are shortly compared with previously manufactured castings of the same type and the results summarizing the found range of macrosegregations of the tested sample are interpreted in the work conclusion.

Calculations of nanocrystalline diamond-covered waveguides based on amorphous silicon
Jirásek, Vít ; Prajzler, Václav ; Remeš, Zdeněk
Nanocrystalline diamond (NCD) coatings on planar waveguides (WG) in the IR region allow to design optical sensors sensitive to absorbers like proteins or other biomolecules. In this contribution, we present a 2D model of a multi-layer WG developed under FEM (finite element method) simulation software Comsol Multiphysics. The model is based on the modified wave equation solved in the frequency domain and includes optical absorption. It was found that for the single-mode WG working in the narrow region of 1550-2000 nm the silicon thickness must be 150-320 nm. It was found that in order to keep a reasonable signal attenuation, the NCD film must be prepared with the optical absorption coefficient lower than 10 cm-1, being a rather challenging task. Dependencies of the signal attenuation on the NCD film thickness, absorbing layer height, its absorption coefficient and exciting wavelengths are presented.\n

Routes planning in Úslava microregion
Kůst, Václav ; Houška, Milan (advisor) ; Jana, Jana (referee)
Czech Republic has one of the densest and highest quality marked hiking trails in Europe, covering completely the whole country. But these trails are not planned with respect to the minority of the population with some kind of handicap. This is a group of families with small children who prefer hiking or biking, for families with strollers and disabled persons in wheelchairs. As the author of this thesis is a councilor of the village Jarov and also a councilor of this village in the Mikroregion Úslava organization he decided to plan a short circular hiking trails with respect to these neglected tourist groups in order to expand tourism in the area of Mikroregion Úslava. These routes may also partly overlap with marked hiking trails (due to their density) and are planned with practical experiences of the author. The results of the thesis will be incorporated into the information brochures of Mikroregion Úslava.
The thesis is divided into theoretical and practical part. Theoretical part describes the methods for solving the travelling salesman problem and provides general information on the concept of micro-regions - voluntary unions of the municipalities. The practical part describes Mikroregion Úslava, the points of interest database creation procedure and planning sightseeing routes for families with children on foot, by bicycle or in strollers. There is also planned a route for disabled persons in wheelchairs in Blovice, which the author of the thesis eventually eliminated from the reasons described.

ŠTANGL, Jiří
Master's thesis focuses on numerical modeling of automotive tasks. The text is divided into two main parts. A fuel supply module is the main topic of all numeric analyses of this thesis and it is introduced in the first part. Basics of theoretical continuum mechanics and finite elements method are also explained in the first part. The second part is split into two main topics of the fuel supply module - material damping and contact numerical modeling. Practical reasons for parameter optimization are explained along with particular optimization results and underlying theoretical background.
