Universal monitoring and diagnostic probe for serial communication
Dvořák, Ondřej ; Povalač, Aleš (referee) ; Záplata, Filip (advisor)
The thesis deals with design of a device for communication analysis in standardized serial interfaces, with differing parameters. The goal of the thesis is a complete design of a device including wiring diagrams, PCB, get PCB alive and design complete device firmware. The device will be able to process and analyze data on selected interfaces. The user controls the device with the use of USB interface, connecting the device with a PC or other computing devices. Communication is done by a simple protocol in ASCII, its design is included in this thesis. The device can analyze errors in the interface and inform the user about them. Firmware should be flexible, to allow the addition of more interfaces and protocols.

Offer of the Building Company to the Public Tender
Dvořák, Ondřej ; Tlustoš, Petr (referee) ; Nováková, Jana (advisor)
The aim of the thesis is the approximation progress public commercial competition in the construction contract for the perspective of the construction undertaking. The theoretical part of the work deals with the concepts and facts of this issue. This section describes, in particular, the legal obligations of the parties involved, and the elements without which you cannot contest. The practical part will focus on the creation of a separate menu in the company and a separate course of public competition. The theoretical part will be drawn up using the supplied materials to commercial contest new nursery school.

Design of Kitchen Sink Production
Dvořák, Ondřej ; Císařová, Michaela (referee) ; Řiháček, Jan (advisor)
The work deals with the design of technology to produce a circular kitchen sink with a narrow flange around the perimeter. The semi-finished product is a 0.8 mm thick stainless-steel sheet X5CrNi18-10. The size of the production series is set at 200,000 pieces per year. Based on a literature search, the technology of deep drawing without thinning the wall was chosen for the production. Then was the sink examined in terms of technology and method of production, which included determining the number of draws, calculating forces and work during forming and other calculations necessary to design a drawing tool. The result shows that to produce the final shape is required two drawing operations with a blank holder and production will be carried out on a hydraulic press HARSLE Y27-200T with a nominal drawing force of 2000 kN. For the first and second operation a drawing tool was designed, for which was prepared the relevant technical documentation. The punch, the die and the blank holder are made of tool heat-treated steel 19 436.9 and they are fixed in welded bodies of common structural steel 11 373. Using the simulation of a drawing was subsequently verified the accuracy of technological calculations and the suitability of the selected method of production.

Manufacturing of a Wheel Nut With Outer Hexagon
Dvořák, Ondřej ; Forejt, Milan (referee) ; Řiháček, Jan (advisor)
The thesis deals with the design of a production technology for a wheel nut with an external hexagon, a tapered seating surface, and a shank. The production series is set at 200,000 pieces per year. The raw material is a coil of wire with a circular cross-section and a diameter of 20 mm made of steel 11 320. After evaluating the specified requirements and conducting a literature review, the production technology of cold forming is selected, specifically the combination of extrusion and upsetting. Three basic production processes are designed, which are subsequently optimized, and their manufacturability is verified using the simulation program Simufact Forming 1.6. For the most suitable production variant, the flow stress, deformation resistance, and forming forces are calculated for each operation. By comparing with the simulation results, the total force required to produce the given nut is determined, which is crucial for selecting a suitable machine. The forming machine used is a CBF 204L with a nominal force of 3,500 kN, for which a three-operation tool is designed. During the tool design, the internal radial pressure acting on the die is also verified. The results indicate that it is necessary to use encapsulation using a single clamp for the second operation. The tool is constructed to be compatible with the parts of the chosen machine according to the provided layout and available machine parameters.

Room Arrangement Generation
Dvořák, Ondřej ; Jelínková, Eva (advisor) ; Petříčková, Zuzana (referee)
The aim of this thesis is to create a program which generates layouts of furniture in a room on the basis of specific constraints. This program is called Spaceout and it is based on genetic algorithms. The thesis also gives a basic overview of existing programs for creating projects of interiors and exteriors. The thesis contains a programmer and user documentation of Spaceout.

Projectional editor for domain-specific languages
Dvořák, Ondřej ; Malohlava, Michal (advisor) ; Šimko, Viliam (referee)
Title: Projectional editor for domain-specific languages Author: Ondřej Dvořák Department: Department of Distributed and Dependable Systems Supervisor: RNDr. Michal Malohlava Abstract: Programming is a craft requiring a good tooling. One of tools selected as crucial for software development is an integrated development environment (IDE) that allows to maintain most of the general-purpose languages. Domain-specific languages grow in a popularity last years, thus it is necessary to support them by IDE as well. Not just a textual or graphical form of DSL sources is suitable for their maintenance, so does the combination of them. One of the promising approaches is represented by a novel method called a projectional editing. Its objective is to show different visualization forms of program source code, combine and manipulate with them at one place. The thought is typically realized by a projectional editor. In this thesis we design a projectional editor for domain-specific languages and provide its experimental implementation. It analyzes potential approaches to a projectional editing and designs their suitable realization in Microsoft Visual Studio. It provides a universal implementation of a projectional editor on the top of Visual Studio as well as on the top of a standalone application. Moreover, it supports...

Vaclav Klaus and "nature"
Dvořák, Ondřej ; Novák, Arnošt (advisor) ; Slačálek, Ondřej (referee)
Thesis is based on the views of authors of sociology of knowledge (Berger, Luckman, Bourdieu) and authors of discourse analysis (Foucault, Fairclough). The central assumption is that knowledge is socially constructed and that this construction has its strong ideological and hierarchic aspects. Author is analyzing books and texts of Vaclav Klaus using the critical discourse analysis. Author is convinced that Vaclav Klaus has a substantive influence on public opinion in Czech Republic. Also author is convinced the struggle in the discussion over environmental topics is based in different basic assupmtions of discussion participant. Thus author decided to analyse the Vaclav Klaus's basic assumptions for the notions of nature and environment.
