The Specifics of Wood-based Constructions Valuation
Hladík, Lukáš ; Čech, Josef (referee) ; Hrdlička, Tomáš (advisor)
The diploma thesis deals with the cost valuation of wood-based constructions, whose amount is growing in the Czech Republic. The aim of this work is to elaborate a detailed itemized budget for three wooden family houses. The price shares were calculated from these budgets; next they were compared with the Regulation 441/2013 Statute book and evaluated. The budgets were also used for a calculation of a unit price, which was compared with a technical-economic index, and commented on as well. On the basis of budgets, the unit price was determined, which was compared with the technical-economic indicator and next comments. The utility properties are compared and evaluated for chosen structures. It is a diffusion-open and diffusion-closed structure. These individual variants of the constructional solution are described and compared with each other. The thesis also presents the basic specifics of wooden-based buildings valuation. In conclusion there is an assessment of adequacy of commonly used price shares of buildings and a proposal for their specification.

User programme for imaging and visualization of quantitative phase from the digital holographic microscope
Hladík, Lukáš ; Kvasnica, Lukáš (referee) ; Uhlířová, Hana (advisor)
This bachelor thesis deals with creation of an user computer program for processing of phase contrast images from a digital holographic microscope. The theoretical section of the thesis contains basic information about obtaining and evaluation of processed images, including a description of their digital representation in the computer. The experimental part deals with techniques and algorithms on which the program is built. This part also contains a description of the graphical user interface of the program and evaluate the impact of different user settings for output files properties.

Switching of spin vortices in magnetic nanodiscs
Hladík, Lukáš ; Pekárková, Jana (referee) ; Urbánek, Michal (advisor)
The diploma thesis deals with the switching of spin vortices in magnetic nanodisks. First, the basic concepts of (micro)magnetism are defined and existing theoretical and experimental achievements in the field of switching of the two basic characteristics (chirality and polarity) of magnetic vortex are summarized. Then the principle of dynamic switching of magnetic vortex chirality using in-plane magnetic field pulse with a well defined amplitude and duration is presented. There is no need to use a certain shape of nanodisks or asymmetry in magnetic field distribution. Nanostructures were prepared by the multi-step electron beam lithography and ion beam sputtering. Individual steps of sample preparation and optimization for the magnetization dynamics measurements are described. Finally, the experimental measurements of the dynamic switching of chirality on prepared samples obtained by transmission x-ray microscopy at the synchrotron Advanced Light Source at Berkeley, USA are presented and discussed.

Determination of acoustic properties of brick body
Hladík, Lukáš ; Skotal, Zbyněk (referee) ; Sokolář, Radomír (advisor)
Bachelor thesis deals with the possibility of increasing the index of the air soundless the wall brick forms. The theoretical part summarizes the present knowledge in the field of acoustic properties of the ceramic shard and also the theory and methodology of the appraisal the index of the air soundless of building materials. Then there is the possibility of using ultrasound for indirect appraisal of the index the air soundless of a brick shard described both in the theoretical part in the form of a research of existing sources and in the practical part.
