The aim of this thesis is to verify a possibility of controlling the crystallisation of aluminium alloys poured in shell moulds in order to achieve directional solidification. For this purpose, new cooling plant has been designed and fabricated. Several sample castings were produced under different initial conditions. Based on the evaluation of measured temperatures, a numerical simulation of heat transfer was created using the ProCAST software. Finally, the sample castings were sectioned into specimens that were, subsequently, metallographically polished and the evaluation of their structure with respect to the amount and types of defects was performed.

This diploma thesis deals with the distribution of lithic raw materials in the Neolithic, whereas the main interest was focused on the area of Germany. The dispersion of chipped and polished stone artefacts in time and space was studied on the basis of available literature. The first part of this work presents existing knowledge about spreading specific types of lithic raw materials. The second part introduces sites from different federal states with finds of chipped and polished stone industry from which was it possible to determine the composition of lithic raw materials collections. The database is part of this work and includes catalogue of sites.

The content of this bachelor work is the project documentation of the hotel On the View in Nový Hradec Králové. The build has three ground floors, without partial basement and it is roofed by flat roof with pea gravel. A build has 2 parts. First part si for guests and second part is for employees. The build has 2 entrance. In the first floor is reception with facility, toilet, restaurant with kitchen, food warehouses, untility room and background for employees. From a restaurant is access to the terrace. In the second and third floor are rooms for 34 guests (of which 2 for handicapped) and background for cleaning women. A Hotel has car park for guests with 13 places ( of which 2 fort handicapped) and car park for employees with 4 places. The construction system is mostly made of polished ceramic blocks Porotherm. Horizontal construction is made up as Porotherm ceiling with brick inserts MIAKO and ceramic-concrete ceiling beams. Part of the proposal is thermal engineering assessment, fire safety solutions and assessments in terms of acoustic and daylight.
