Possibility of using EMW radiation for killing biotic pests
Gintar, Jan ; Klečka,, Tomáš (referee) ; Pěnčík, Jan (referee) ; Šuhajda, Karel (advisor)
The remediation of building elements and structures in terms of moisture and sterilization (inactivation) of biotic pests is dealt with quite often in construction practice and in the construction industry itself, and is thus a topical issue. The issue is dealt with by specialized companies that know the use of available technology on the market, or are themselves involved in the development and improvement of these devices. Several methods are known for the removal of moisture and sterilization of biotic pests, with sufficiently high-quality data on the technology used, the suitability of the equipment used, a more detailed description of the application of the methods themselves and the results themselves. The methods themselves, for removing moisture and eliminating (inactivating) biotic pests, must be chosen according to individual requirements, as some methods will be more appropriate (more effective) and some less suitable. For the practice itself, however, it is important that the methods are sufficiently effective and at the same time available to the wider public (their economic side). In my dissertation thesis I focus on the potential of EMW radiation utilization not only for liquidation of biotic pests (fungi, fungi, wood decaying insects), but also elimination or reduction of necessary conditions for survival or development of these biotic pests. Therefore, my work also focuses on the presence of moisture, because moisture is a common factor in the vast majority of problems associated with the occurrence of biotic pests. Due to its intensity, it is one of the less time-consuming method and therefore a more cost-effective (economically) method. The research I conducted at VUT FAST focused on the use of microwave radiation in the control of biotic pests, under conditions that are close to those on real constructions. The use of a microwave method to eliminate biotic pests and at the same time to remove moisture has proved to be advantageous.

Roof structure of construction for social purposes
Bašista, Ján ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The work treats the static recalculation of an existing roof structure of a construction for social purposes and proposes two variants of the design of a new roof structure. The construction has a rectangular ground plan of 30 m x 47 m and the roof structure is placed on the load bearing circumference concrete walls. Except for the load constituted by the function of the construction and by the climatic area, an extra load of 2 tons suspended at any place of the structure is considered because of the special requirement of working and technological equipment. The variant no. 1 is designed from the steel S355. The variant no. 2 is designed as a combination of the wood GL24h and the aluminium EN-AW 5083. Both of the variants have 11 transverse load bearing girders. The purlins are perpendicular to the girders and are placed on them. Stiffness is secured by roof stiffeners.

Community House - Rectory
Loudilová, Martina ; Matoušková, Petra (referee) ; Šindlar, Jiljí (advisor)
The theme of the dissertation is design of new building of community center with a vicarage. The building is designed as a flat for a vicar, office of a vicar, new rooms for meeting of the churchgoers and new garden. The vicarage is designed near of church. The vicagareis designed in an area, which is prepare for building of cottages. The old vicacare is in old house in the other part of street Kostelní, than is the church. Existing flat for the vicar is unsuitable. Theobject is designed with one or two floors. The object is designed of tree parts: living part – a flat of the vicar and a flat for visitors, a community center – a parish hall and a hygienic rooms, an office part – an office of a the vicar and a clubroom. All parts of building are divide with fiction, design and used materials. The building is designed with a traditional materials as wood, concrete, masonry. The shape of building is designed from three diferent blocks. An parish hall i designed with rectangle layout, in the hall are designed two windows. The north-west corner of hal lis designed higher than other part sof room, because this corner is situated to church. This window is designed with frame in cross shape. The second window is connection between the garden and hall. The external fasade is designed from smooth concrete with links, that are designed in cross kapes. The links are designe as some crosses, that are designed in gold section. The office of vicar is designed with wood arc beams. The external fasade is designed from titanzinc sheets. The fasade is designed as wall and roof. The end fasades are designed from glass walls, because wood beams are a dominant of this part of building. The living part of building is designed with two floors. Th structure is designed with traditional technologies from masonry and concrete or wood slabs.

The analysis of acoustic properties of innovative wood-based materials
Svojanovský, Jan ; Nop, Patrik (referee) ; Jirásek, Ondřej (advisor)
The content of this work is research of innovative wood-based materials in the acous-tic perspective. Basically, the goal is to determine the influence of the internal structure of the wood-based material on variables, which are sound speed, acoustic resistance, or acous-tic constant. In total were measured 15 samples, each one was made in a different way. Each sam-ple was weighted, and the length of its sides was measured. By using the ultra sonic timer, it was measured the time of the sound impulses, which go through the samples in all of their axes for the purpose of observation the influence the fibers on speed of sound in the materi-al. The next thing to do was to determine another magnitude, which describe acoustic of the material. All measurements were taken in room conditions (room humidity). Six of the sam-ples, which were randomly selected from those 15 samples, were measured once again after two weeks. In those two weeks were all the samples saved in air-conditioned place in which was the room humidity distinct lower. In the end all the samples were compared with each other and they were also com-pared with materials which are commonly used in production of musical instruments or acoustic components. Possible use in the music industry was assigned to each sample.

Cost comparison of houses made of classic materials and houses made of natural material
Lošáková, Jana ; Gilar, Ing Přemysl (referee) ; Výskala, Miloslav (advisor)
This diploma thesis is focused on a comparison of construction cost of the house made of classic materials with the equivalent made of natural building materials and consequently on comparison of both construction variants. In order to perform those tasks, the used natural building materials were defined. Furthermore, the specific options of usage of these natural building materials as well as the used composition structures were introduced. The thesis concludes with a price calculation of the constructions made of natural building materials which were not available in the common budgetary software. The appendix of the thesis contains budgets for the first variant, where the house is made of natural building materials, and also for the second variant, where the house is made of classic materials.
