Application of modern technologies for the production of spare parts airsoft guns
Král, Ondřej ; Zemčík, Oskar (referee) ; Jaroš, Aleš (advisor)
This bachelor thesis describes design and manufacture of airsoft spare parts. Selected spare parts were hammer and spring holder, which were designed in 3D parametric software Autodesk Inventor 2016. Chosen method to manufacture spare parts, was Fused Modeling Deposition, which is part of Rapid Prototyping technology. The device for producing parts was 3D printer uPrint. The manufacture of silicon mould was based on printed spring holder, which was used for parts manufacture, by casting plastic materiál. Thesis is completed with a technical-economical evaluation, in which it was found that the silicon mould casting is more profitable in the production of more parts.

New synagogue in Trutnov
Král, Ondřej ; Benedek, Borislav (referee) ; Dulenčín, Juraj (advisor)
The diploma project is an elaborate design of a synagogue including associated facilities for the Jewish population in Trutnov. The proposition is designed in the phase of architectural study. The location of the proposal is placed near the historic centre of Trutnov. The intention of the proposal was to respect the conditions of the surroundings and relations with the environment and at the same time provide the Jewish population with representative and sufficiently sized spaces for their activities. The main building also provides an opportunity for chance encounters between the Jewish population and the public, thus indirectly contributing to the growth of the Jewish community and awareness of Judaism as such. The main building is a three-storey building placed in the terrain so that it forms natural "stairs" in the slope of the hill. The roofs of the building also serve as walking terraces, which ensure the accessibility and walkability of the plot. In the basement there are garages, the 1st floor contains a kosher restaurant and space for co-working. On the last floor, a mikveh, a space for the administration of the Jewish community and an archive of Jewish literature are designed. The second designed building is a newly designed synagogue, which stands on the site of the old synagogue. The original synagogue was burned out during Crystal night. The design pays respect to the original synagogue by including the floor plan of it in the paving pattern.

New synagogue in Trutnov
Král, Ondřej ; Gürtler,, Ivan (referee) ; Dulenčín, Juraj (advisor)
Topic of this master thesis is a design of a synagogue together with Jewish community facilities in Trutnov. The thesis is made in the phase of architectural study. Assigned site is located near the historical center of Trutnov. There is a reminder of the old synagogue that was burned out during WW2. There is also newly reconstructed park around it. Main purpose of the proposal is to respect the park with old synagogue and connect both places so anyone can share the experience of reminder of the past together with new function. The designed volume opens towards the street and communicates with the new park with its vast openings. Function of the new building is inspired by the idea of Judaism. It is connected not only with the synagogue but also with communal life, education, celebrations, or art. That is why the proposal is connecting all the functions under one roof and the synagogue is “guarding” all of them from above. The building has three floors. On the lowest floor, there is underground garage. On the ground floor we can find space for Jewish community administration, room for exhibitions, mikveh and kitchen part for the kosher restaurant. The upper floor is mostly terrace. There is only kosher restaurant and synagogue.

Design of the hammer set
Král, Ondřej ; Haltof, Vladimír (referee) ; Škaroupka, David (advisor)
This bachelor’s thesis is focused on the design of a product family of hammers by the means of generative design. The core of this thesis is the creation of an algorithm which will generate hammers of unified visual style, but varying properties based on input parameters. It is necessary that these hammers are in shape, ergonomics and dimensions adequate to preferences of the target group of professional workers and that they are producible in series and from commonly used materials. The output is a set of three hammers with different mass and dimensional properties.

Design of steam boiler with grate firing burning contaminated wood
Král, Ondřej ; Křemínský, Pavel (referee) ; Baláš, Marek (advisor)
The master´s thesis deals with steam boiler design that burns contaminated wood with output 55 tons of steam per hour, steam pressure 4,2 MPa and temperature 423 °C. First two chapters focuses on stoichiometry and calculation of heat losses and boiler efficiency. Great part of thesis constitutes of thermal and dimensional calculations of every heat transfer surface. Some specific boiler parts are described considering special fuel properties. Final chapters contain pressure losses calculation of flue gas and heated medium for pumps and fans design. Drawing is also part of the work which is included as an attachment.

Osteled 7c-7d Horsens Refurbishment
Král, Ondřej ; Žalmanová, Petra (referee) ; Šindlar, Jiljí (advisor) ; Kolář, Radim (advisor)
Project created during study program on VIA university in Denmark gave form to the following bachelor’s thesis which further develops it into the level of building permit documentation and documentation for execution of the project. Object of the study is located in Horsens in a residential area among several identical residential buildings. The project focuses on refurbishing this building and upgrading it’s standards for living with emphasis placed on economical, energetic and social sustainability. The main idea is to preserve the authenticity of the object by respecting original form and materials while adding modern elements. At the same time to provide diverse and pleasurable living spaces in dwellings, connection with greenery and possibilities of social contact of residents. The load bearing structure of the building is preserved, staircase area demolished and replaced by new communication core including stairs and elevators. Roof truss system and roof construction is determined to be replaced. Project is designed as barrier-free.

Optimalization of cutting process for machining of aluminium profile on CNC centre
Král, Ondřej ; Fiala, Zdeněk (referee) ; Jaroš, Aleš (advisor)
This master‘s thesis deals with the suggestion of suitable tools for milling aluminum alloys profiles for the construction of aperture fillings and their aplication to a CNC machining center for increasing the efficiency of the cutting process. The first part of the thesis is focused on the description of the company and the workplace of production of aluminum alloys constructions. The following pages contain description of standardized products, which are used to identify the test profile that is part of the experimental verification. Next part of this thesis is characteristic of aluminum alloys and tool materials suitable for their machining. Second part of this work contains an analysis of the current state, suggestion of new cutting tools and their application to the production proces. At the end of this thesis there is the technical-economic evaluation that deals with the time and economic savings of the applied design.

Wind energy
Král, Ondřej ; Brázdil, Marian (referee) ; Kracík, Petr (advisor)
This bachelor’s thesis discuss wind energy sector. The first chapter focuses on basic construction types of wind power plants, their classification and description of the main parts. Basic physical principles by which electrical energy is produced, presents the next section, which deals with the lifetime of wind turbines, too. The final chapter describes the development of wind power in history, wind energy is here compared with other energy sources, and finally it is dedicated to matter of wind turbines’ energy payback.

Interval linear systems with linear dependencies
Král, Ondřej ; Hladík, Milan (advisor) ; Rada, Miroslav (referee)
The main problem discussed in this thesis is about finding an enclo- sure of the solution set of an interval linear system with linear dependencies. We get familiar with definitions from interval arithmetic and analysis. Then we extend them to matrices and linear systems, where we introduce several modern approaches to finding an enclosure and divide them thematically. Most of them are implemented in MATLAB using INTLAB library. We compare their precision and computational time on Toeplitz, symmetric and random matrices. For depen- dencies we design our memory saving representation. The results are interpreted and the final function, which can compute either fast, sharp or memory efficient, is build on individual methods. Powered by TCPDF (www.tcpdf.org)
