District heating systems in the Czech Republic in the context of legislative changes
Hylas, Martin ; Poul, David (referee) ; Putna, Ondřej (advisor)
The bachelor thesis focuses on the analysis of the issue of district heating (DH) with regard to legislative changes in the European Union. The first part deals with the analysis of the issue and the evaluation of the state of CZT in the Czech Republic. The European Union's position on climate change, caused by increasing greenhouse gas emissions, which are significantly produced by DH sources, is also discussed. The research part ends with an analysis of possible changes in the heating industry leading to the fulfillment of legislative requirements in the future. The second part of the bachelor's thesis deals with the elaboration of a case study of the change of the fuel mix for the heat source in the existing locality with the use of the technical-economic model. The main goal is to evaluate the usability of renewable resources (biomass, waste) as primary fuels instead of natural gas. The result of the practical part is a comparison of individual variants and changes in the cost of producing 1 GJ of heat compared to the reference variant.

Bonding of thin metal sheets
Poul, David ; Kubíček, Jaroslav (referee) ; Dvořák, Milan (advisor)
Bachelor thesis is focused on theory and methods of adhesive bonding. Experimental part is focused on two topics: determining dependences of bonded joint shear tension on a cure time and determining dependences of bonded joint shear tension on a size of contact area. Loctite SI 5399 RD acetoxy silicone one component glue was used for these experiments. At determining dependences of bonded joint shear tension on a size of contact area tension is raising, but the grow wasn’t directly proportional on the grow of size of contact area. Determining dependences of bonded join shear tension on a cure time it was proved, that tension is raising first 24 hours very quickly. After this period is process slowing down and tension is increasing to its maximum. After 18 hours bond tension is solid enough to be handling, but 24 hours of curing time is more secured.

Rail transport in practice
Poul, David ; Pluskal, Jaroslav (referee) ; Gregor, Jiří (advisor)
The diploma thesis deals with railway transport describes its role in combined transport and compare key aspects with road transport. As part of the diploma thesis, a detailed database of railway tracks in the Czech Republic was created, on which the route planner was built with the possibility of setting waypoints. The route planner also includes the implementation of exclusion activities. A comprehensive technical-economic model of railway transport was created with four calculation models and detailed investment planning, thanks to which is possible to assess whether the purchase or lease of train sets is more advantageous when making investment decisions. Furthermore, a technical-economic model for the branch line was created. The last section deals with the created transport model for the catchment area for 8 localities and 5 types of transported waste/commodities. The transport model was used to evaluate two selected areas – the South Moravian Region and Kolín.
