Electronic notice board LCD
Bureš, Michal ; Kaczmarczyk, Václav (referee) ; Bradáč, Zdeněk (advisor)
This diploma thesis deals with the research of existing solutions of electronic information systems. The purpose of this survey is to inspire what is offered to users of these professional systems, or what users expect from these systems. Based on the acquired knowledge, the thesis also deals with the design of its own system, which can serve as another alternative to professional solutions of companies on the market, in the sense of the concept of solution of the given task. After the design of the system, the thesis deals chronologically with the selected "tools" used for the actual implementation of the assigned task Electronic Information Boards. Both hardware and software parts of the task, which form the majority of this thesis. At the end of the work are presented practical results.

Design of working arm for threading machine
Řezníček, Marek ; Tůma, Jiří (referee) ; Pavlík, Jan (advisor)
The aim of this work is to propose the construction of working arm threading / drilling. Working arm provides "its" vertical position of the tool axis in the working range and reduces the force effect of cutting forces and weight. The work includes 3D models and drawings, including the calculation of the components.

Bioinformatics Tool for Protein Structure Prediction
Plaga, Michal ; Burgetová, Ivana (referee) ; Martínek, Tomáš (advisor)
The goal of this thesis is test and comparation of the offline tools for prediction of protein structure and creation of metaprediktor, which allows the user to select the appropriate tool, according to given parameters. Testing tool is based on a dataset of proteins, which is based on the SCOP database and it is trying to be as balanced as possible to include proteins from different families and thus could best evaluate individual tools. The results of this thesis are requirements of metaprediktor and also which data and settings can be allowed and processed and how it will be implemented.

Protein Structure Prediction
Tuček, Jaroslav ; Martínek, Tomáš (referee) ; Burgetová, Ivana (advisor)
This work describes the three dimensional structure of protein molecules and biological databases used to store information about this structure or its hierarchical classification. Current methods of computational structure prediction are overviewed with an emphasis on comparative modeling. This particular method is also implemented in a proof-of-concept program and finally, the implementation is analysed.

Web Server for Protein Structure Prediction
Votroubek, Lukáš ; Očenášek, Pavel (referee) ; Burgetová, Ivana (advisor)
This work deals with proteins, especially with their structure and kinds of tertiary, or 3D, structure prediction. Tertiary structure prediction is very important for function prediction of this vitally important substance. Bioinformatics do this prediction much more effective and faster, because classical methods of structure prediction directly from molecule are very expensive and slow. On the other hand they are much more exact. Objective of this thesis is to describe tertiary structure prediction methods, describe used tools and possibility of automatic communication with them. Next objective is describe implementation of server, that will serve to protein engineers for more effective finding of information about tertiary structure from more servers without requesting each of them separately. Results of testing will be described in this work too.

Evaluation the properties of the cutting edge in fusion and flame cutting by solid state lasers
Dočekal, Miroslav ; Berka, Roman (referee) ; Mrňa, Libor (advisor)
The thesis compares oxidation and fusion laser cutting methods in the production of sheet components called Trager consoles. Individual methods of laser cutting are compared in terms of achieved quality and properties of cutting areas. Consequently, the effect of these properties on consecutive technological operations, which are mainly threading and pressing the nuts into components, are evaluated. In the experimental part of the thesis the roughness of cut surfaces was measured and the cuts were classified into quality classes according to the ČSN EN ISO 9013 standard. Metallographic samples were taken in order to measure hardness and determine its course in the direction from the cutting edge into the material. The metallographic samples were further used for capturing detailed images on the microscope and assessing the quality of nuts pressing. Afterwards, the cut moments affecting taps were measured in order to verify the impact of cutting edge properties on threading. These measurements provided sufficient data for comparing the influence of cutting edge properties in individual methods of laser cutting on consecutive operations. Finally, individual methods were compared in terms of production costs. According to all the data and the conclusions reached, fusion method was identified as the most suitable method of laser cutting for components manufacturing.
