Difuzní vlastnosti OSB desek v důsledku zasažení nadměrnou vlhkostí.
Žižková, Lucie ; Vertal', Marián (referee) ; Chybík, Josef (referee) ; Bečkovský, David (advisor)
The presented dissertation focuses on the change of diffusion properties in oriented strand board (OSB) panels after exposure to excessive moisture. OSB panels undergo a change in their diffusion properties after being affected by excessive moisture and subsequently dried, causing them to deviate from the original design of the wooden wall structure. The aim of this study is to describe the experimentally measured change in diffusion properties and incorporate it into the composition of a real wooden wall structure, evaluating its performance through computer simulation. The introduction of the dissertation provides the theoretical basis for the experimental section, which includes measurements of water absorption, diffusion properties, and the risk of mold growth. The experimental section describes the approaches and methods used to achieve the objectives of the dissertation. The measurements were conducted on test samples of OSB panels in the laboratories of the Institute of Civil Engineering. After being exposed to excessive moisture, the test samples were dried using two drying methods. The dried test samples were placed in testing assemblies, where diffusion was measured using the dry cup method. The measurements were carried out in two stages, with more than 80 samples measured in each research stage. In the final part, the measurements are evaluated through graphs. The change in diffusion properties was then incorporated into the composition of a real wooden wall structure and assessed using computer simulation, which is more commonly used in practice according to ČSN 73 0540 (Czech Technical Standard).

Vehicle Hydropneumatic Unit
Koudelka, Roman ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
This diploma thesis, following the bachelor's thesis, is devoted to the gas-liquid unit of a vehicle, as the central element of hydropneumatic suspension. The aim is to dimension and construct this component and integrate it together with other elements into a complex suspension system. Based on possible forms listed in the research section, regarding to current development trends, the form of the unit is chosen. The practical part begins with simulations comparing a hydropneumatic with a conventional suspension system. After solving this issue, it is possible to proceed to the dimensioning of the basic parameters of the unit and then to its construction, respecting the relevant strength calculations. The last step is to build a conceptual design of the whole hydropneumatic suspension system.

Static analysis of moving skyscraper
Jedlička, Michal ; Martinásek, Josef (referee) ; Vlk, Zbyněk (advisor)
The thesis is about static analysis of moving skyscraper (inspired by The Dynamic Tower). There is a rotation of each particular floor around its axis independently on each other. In this thesis, moving skyscraper is solved as a whole piece with specialization in the moving floors and their mounting on the core of the building.

Family house
Zachovalová, Jana ; Pilný, Ondřej (referee) ; Berková, Petra (advisor)
This bachelor thesis discusses a project of a detached house with comercial space, which is located in Chrudichromy district. The house has two floors and basement. In the basement there are two deep-level garages. The comercial space will be engaged as a hairdresser's. This is situated on the first floor. The house is projected for five-member family. The enclosure wals are made of Porotherm 30 AKU Z PROFI bricks and are insulated by the Etics systhem. The pack frame is made of POT beams and ceeling beams MIAKO. The house has a double-surface ventilated collar roof. The Bachelor Thesis serves as a contract document for execution of the project.
