Study of thin transparent films properties
Schmiedová, Veronika ; Veselý, Michal (referee) ; Zmeškal, Oldřich (advisor)
The main aim of this bachelor´s thesis is a study of thin transparent layers of organic materials (PPV, P3HT, TiO2, DPP). The theoretical part describe the methods of quality examinations of their surface, mostly the use of optical and interference microscopy. For elaboration of data was used the image analysis via HarFA program. Thickness of layer and the index of refraction was provided by interference microscope. From the interference images was identified the amplitude of groove for various values of treshold, but mainly the interface inhomogenity of groove, which proofs the surface inhomogenity of samples. For the images taken by the optical microscope were allocated the average errors (but also errors of superior sorts) defining the surface inhomogenities of samples. The conlusion of this study compare the results of both methods.

Static solution of swimming pool in new mountain hotel building
Krtička, Jakub ; Laníková, Ivana (referee) ; Zlámal, Martin (advisor)
The static solution at the new building mountain hotel The thesis deals with design and static calculation of pool tank, which is supported by columns and walls. Pool tank is designed as swimming pool with plan dimension 25 x 10 meters and with changing depth from 1,2 to 1,8 meters. The support of pool tank is in distance 5,02 x 5,05 meters. The adjacent ceiling is placed on the walls of tank and separates pool and technical areas. The calculations of inner forces were realized by computational programm for two models a) without decline of supports, and model b) with decline of supports. The design of reinforcement is performed for the bottom and walls of tank. The deformations modeling was made at the other part of the thesis. All results were evaluated and summarized at the conclusion. Drawing documentation was made subsequently.

Algorithms for computation of the dimensions of state space attractors
Götthans, Tomáš ; Slanina, Martin (referee) ; Petržela, Jiří (advisor)
The geometry of chaotic attractors can be complex and difficult to describe without some mathematical tool. The topic of this contribution is the realization of program for computing the dimensions of state space attractors. We can also find out if the system is highly sensitive to initial conditions. First we need to numerically integrate system of equations, create a data set and finally we can estimate the capacity or Kaplan-Yorke dimension. The main objective of derived program is to analyze and determine chaotic behavior providing a chance to discuss the accuracy of computation engine and theoretical value.

Use of Agile Methodologies in the Data Warehouse Design
Janečka, Pavel ; Kreslíková, Jitka (referee) ; Bartík, Vladimír (advisor)
Scope of this master’s thesis contains agile data warehouse design. It begins with a brief demonstration of data warehouse issues, shows the architectures dimensional data warehouse, corporate information factory and data vault. Furthermore, the thesis introduces agile methodologies suitable for data warehouses. Main part of this thesis focuses on the data warehouse design and development in Kentico Software s.r.o. using the modelstorming, shows implementation of universal ETL process for loading dimensional data warehouse, designs ETL processes, data warehouse storage and presentation layer. In the end, the thesis discusses future extensions to the data warehouse such as knowledge discovery module or large-scale data expansion.

Plumbing Systems Modernization for Sport Centre Buildings
Kohutek, Ivo ; Vrána, Jakub (referee) ; Bárta, Ladislav (advisor)
This thesis deals with the reconstruction of sanitary installations in the multi-purpose sports facility STARS in Třinec. It is a large complex with an administration building. The theoretical part is focused on heating and distribution of hot water. It considers multiple solutions to the problem. The practical part then deals in depth with one of the discussed options in a selected few buildings.

Evaluation of dimensional and shape accuracy of components made of plastic
Tuza, Marek ; Dobrocký, David (referee) ; Sedlák, Josef (advisor)
The aim of this thesis is to evaluate the dimensional and shape accuracy of components made of plastic. A total of 10 samples, produced by two types of production, extrusion and 3D printing using the FFF method, were used for this purpose. The semi-finished products were milled after production, which resulted in samples of the required dimensions. The samples were milled on one side without cooling emulsion and on the other side with cooling emulsion, which significantly affected the resulting shape accuracy values. Thus, a total of 20 surfaces were evaluated. Two parameters were selected to evaluate the dimensions, namely distance and parallelism. When measuring the shapes, 11 parameters were evaluated using a 2D roughness profile and a 3D surface texture. One of the most used parameters that was evaluated when measuring shapes was the arithmetic mean deviation of the roughness profile, which is denoted as Ra. The research found that the highest accuracies were measured for the material PA produced by 3D printing and milled with a cooling emulsion. At the end of the practical part, the author also makes recommendations regarding the practical use of materials.

OLAP Analysis of Big Data
Králik, Dalibor ; Smejkal, Milan (referee) ; Hruška, Tomáš (advisor)
The goal of this bachelor’s thesis is the creation of three OLAP data cubes, which will solve the problem of foreign trips of students and employees of BUT. The primary purpose of data cubes is to quickly provide correct data for BUT analysts. SAP Business Warehouse software is used for their modeling and implementation, and SAP Analysis for Microsoft Excel software is used for testing. After successful design, implementation and testing, BUT has these three OLAP data cubes on the production and development servers of SAP Business Warehouse, to which BUT analysts have access. Thanks to this work and data cubes focused on foreign trips, analysts and BUT employees in managerial roles have the opportunity to quickly access data and analyzes that serve to support correct decisions related to the functioning of BUT.
