Principles of transmission of optical beam by optical fiber
Lásko, Jan ; Rampl, Ivan (referee) ; Šporik, Jan (advisor)
The work is focused on spreading beam optical fiber parameters which may affect the passage of the beam fiber dispersion, attenuation, numerical aperture and mods. In sub-sections there are examples which solve the problems and also practical examples of visualization of numerical aperture, the chromatic, and polarization dispersion. The basic features of the new technology of fiber called microstructure and problems connected with it are described on the paper.

Slab bridge at Kájov Village
Pavlíček, Zdeněk ; Zvolánek, Lukáš (referee) ; Panáček, Josef (advisor)
Topic of this bachelors´s thesis is project of bridge on road II/166 near to Kájov village. Aim of the bridge is transportation across Chvalšinký potok. Three variants of possible solution were designed. In first and second solution were used prestressed slab structures. In third prefabricated prestressed beams. Selected variant was prestressed slab structure with rectangular cross-section. Thesis contains statical analysis, drawing documentation, text part and visualization of designed constuction.

Slab bridge in the Litovel town
Majer, David ; Svoboda, Adam (referee) ; Panáček, Josef (advisor)
The subject of this bachelor’s thesis is the design and analysis of perpendicular, one-span bridge construction across the millrace for electrical power station in the Litovel town. Object is located to 2nd class road II/449. Three variants were designed - prestressed trapezoidal slab, prestressed double-beam construction and construction of four prestressed girders of shape I. After these variants were weigh up and the first one, with the length of cantilevered construction 22,5 m, was chosen for analysis. Calculation of load effects was made by software Scia Engineering 2013, it was compared to a manual calculation and the analysis was made by manual calculation according to current standards.

Bridge on the I/44 road
Majer, David ; Pachl, Radek (referee) ; Panáček, Josef (advisor)
The subject of this thesis is the design and analysis of five-span bridge construction across the railway on the route Zábřeh - Šumperk and the Morava river. There will be made separated bridge for each direction, only right bridge is considered in the thesis. Object is located to 1st class road I/44 on the route between Mohelnice and Jeseník. Three variants were designed - two prestressed chamber girders, one prestressed chamber girder with prefabricated consoles and construction of concrete slab mixed with two steel girders. After these variants were weigh up and the first one, with the length of cantilevered construction 235,6 m and maximum lenght of span 60 m, was chosen for analysis. Calculation of load effects was made by software Scia Engineering 2013 and the analysis was made according to current standards by manual calculation depending on limit states and their influence on the design as well. Drawing documentation and visualization are also part of the thesis.

Biomedical data visualization using Matlab
Zvončák, Vojtěch ; Mekyska, Jiří (referee) ; Galáž, Zoltán (advisor)
The thesis deals with the visualization of biomedical data in MATLAB environment. The thesis contains following statistical methods and their descriptions: P-P plot, Q-Q plot, histogram, box plot, kernel denstity estimation, scatter plot and several time series metrics. Some functions are programmed from buil-in functions of MATLAB and others using external functions, which are changed to fit to this thesis’s purpose. First part of the thesis conserns theoretical background, whereas the second part conserns practical programmed realizations of mentioned functions. The program contains a graphical user interface - GUI, which the thesis describes in detail. The purpose of the GUI is to ensure ease of use and also data processing. The output graphs of GUI are shown in chapter 5. The last part deals with the possible extensions of the program.

Visualization of PLC/BPL communication in the map
Klíma, Petr ; Rusz, Martin (referee) ; Benešl, Lukáš (advisor)
The bachelor thesis deals with the implementation of an application for visualization of the PLC communication network (PowerLine Communication). The principle, advantages, disadvantages and variants of this type of communication are analyzed. Attention is also given to the use of this technology, especially in the construction of smart grids and for the diagnosis of cable lines, which is also used by the application. The thesis also deals with the problem of predicting the state of cable lines and the parameters on which this prediction is based. Some current possibilities of map visualization are also discussed and the application itself is created using the javascript library Leaflet and static map tiles. The application is focused on BPL technology, but it allows storing data on any connection made by any transmission technology. It allows displaying information about the network and displaying network elements on a map, filtering BPL connections according to the state of the cabling, configuring individual parts of the topology and the ability to create and read database backups. The behavior of the application can be easily modified by editing the file with constants.

Integral frame bridge
Dobeš, Marek ; Šopík,, Leonard (referee) ; Koláček, Jan (advisor)
The aim of this diploma thesis is the design and assessment of a single span inclined integrated frame bridge structure over rail tracks. Three preliminary studies have been designed and then a best variant was selected for more detailed analysis. A reinforced concrete slab with steel girders with a span of 28.39 meters was developed. The model was developed using the MIDAS/Civil program and the limit state assessment was carried out using the MS Excel program. The procedure and dimensioning of the calculation is carried out according to valid standards and regulations.

Box girder bridge
Vostal, Lukáš ; Pecha, Jakub (referee) ; Nečas, Radim (advisor)
The subject of this thesis is the design of a prestressed box girder construction with several spans. Two variants are designed and for detailed solving was chosen the variant of the box girder. The length of loadbearing structure is 212 m, the longest span has 60 m. The calculation of load effects is done by software Scia Engineer 19.1. Drawing part is done by software Allplan Engineering 2021. The thesis includes drawings, representation of the construction proces, visualization and a structural design. Designing and assessments were made according to currently valid European standarts.

Electronics and CNC milling machine control
Tmej, Tomáš ; Zuth, Daniel (referee) ; Marada, Tomáš (advisor)
The diploma thesis focuses on the electronics design of a hobby CNC milling machine. There are analysed and described the individual electronic parts and components related to this problematic. Three electronics suggestions are made, these suggestions are compared. Then, one of these variants is selected and implemented. Next, is created a relevant PLC program to control the CNC milling machine with visualization for easy control.
