Optimization of vortex pump
Šmíd, Pavel ; Bílek, Martin (referee) ; Pochylý, František (advisor)
The aim of this labor is to optimize the vortex pump. When this pump should find application on the field of health like human heart for extracorporeal circulation. We will deal with the analysis of shear stress in the pump and its size of it and consider the use nonwetting surfaces to reduce the shear stress values. All our analysis will be made by CFD calculations.

Pump design
Šmíd, Pavel ; Šperka, Oldřich (referee) ; Klas, Roman (advisor)
The aim of this labour is to analyze the structural design of pumps used in the present time. First, we focus on the distribution of pumps by type of energy conversion, and there are hydrostatic and hydrodynamic. Will further comparison of these types, and enter the region of their optimal application under specific speed. This labour will focus only on the hydrostatic pumps when we will do an analysis of design performance of the individual pumps and we'll give the advantages and disadvantages of the specific pumps. We shouldn´t forget the basic technical parameters and individual areas of practical use these given types. At the end of the labour will be processed the basic equations and the ideal characteristics of pumps.

Possibilities of Financing of Fixed Assets Acquisition
Hlaváčková, Petra ; Šmíd, Pavel (referee) ; Zemánková, Lenka (advisor)
This diploma thesis focuses on the oportunities of financing the acquisition of fixed assets for a particular company. The first part introduces and explained the basic theoretical concepts especially fixed assets, financing assets and financial analysis of the company. In the next part selected company is presented and analysed. The thesis focuses on offering banking institutions and leasing comapnies mainly on the long-term bank loans and financial leases. The aim of this thesis is to find the most effective option of financing the production facilities of the company. At the end of thesis is proposed the optimal method of financing the acquisition of fixed assets for a particular company.

Komparace užití účetnictví a daňové evidence v dřevařském podnikatelském subjektu
Šmíd, Pavel
This bachelor thesis deals with comparation of accounting systems, such as tax records and accounting. The advantages and disadvantages of each subsystem are described in theoretical part of the thesis. In following parts the thesis copes with the differences between revenues and incomes, between costs and expenses and compares records of receivables and obligations in each system. The individual steps that supervene during the transition from the tax record to the accounting and differences between them are analysed and compared in the practical part of the thesis. Last but not least, the thesis deals with the calculation of income tax of natural persons, both in the tax records and in the accounting, the thesis also contains the calculation of the income tax using lump sum of expenses. The bachelor thesis copes with legal acts of Czech Republic, which are enacted and enforced in the day of completion of this work.

Vliv modifikace na pevnost lepení buku
Šmíd, Pavel
This diploma thesis is focused on the influence of thermal modification on the strength of bonded joint in tension according to ČSN EN 205. For the purpose of this work was used beech wood. The thermal modification of the test samples was performed at temperatures of 160 °C, 180 °C and 200 °C. The selected bond strength adhesives were melamine-urea formaldehyde adhesives (MUF), phenol-resorcinol formaldehyde adhesives (PRF) and one-component polyurethane adhesives (PUR). In addition to the thermal modification the effect of plasma modification on bond strength is also determined. The test lamellas were plasma treated (DCSBD) prior to gluing and pressing. The result is the determination of the tensile strength of the bonded joint in all the above-mentioned modifications and comparation of the results.

Analysis of fishing pressure at sport fisheries managed by Czech Angling Union under the united fishing system.
ŠMÍD, Pavel
The goal of the thesis was to analyse the fishing pressure, number of visits and number of catches in sport fisheries managed by Czech Angling Union (CAU). The selected data, mainly concerning the sport fisheries managed by South Bohemian Board of CAU, were graphically presented. At the trophy fishery Vltava 24, daily data were evaluated and the behaviour of fishermen was compared during the first two years of the new management (2010 and 2011). The second part of the thesis is aimed at the analysis of the united system of fishing management within the whole CAU and suggests a new system of financial flow. CAU is composed by 7 regional boards; however, it is possible to buy united fishing permit valid in all the fisheries of CAU. The financial budget coming from these permits is redistributed only according to the weight of killed and recorded fish. This system is advantageous mainly for regional boards with a big amount of fishermen and high fishing pressure at their fisheries; it is less advantageous for regional boards managing large areas. Within the thesis, a new model for redistribution of the financial budget was created. Except for the weight of killed fish, it includes other expenses connected with the management (fishing guards, lease of fishing waters, etc.) and the number of fishing visits. The model was provided to CAU for future negotiation.

Backflow of catchs on trout district in river - basin of upper Vltava
ŠMÍD, Pavel
Backflow of catchs on trout district is important indicator of fishing maintenance. On trout district were to be in former times given stool duties betray into order about usage of district. Planned fish stocking has becomingly complete structure of original fish guilds in district with old availability. Objektive of work will be review in agreement with fishing statistician level of maintenance on district by indicator of backflow catch in piece and weight , but also in agreement with structure of valuable and additional, eventually harmful kinds of fishs. Useful information follow also from fishing pressure (visit rate) on fishing district. Important ratings are also segmentation of district, number of migration road-block, flow of water, type of gout near coast, segmentation of stream, bolthole capacity, vegetative company etc . Therefore will serviceable separate up under consideration districts in river - basin of upper Vltava also accordance with these characteristics in mountain and piedmont zone of southern Czech. Conclusion of work will contain draft of measures destined to improvement maintenance of trout districts.
