Equipment for punching profiles
Hudeček, Jan ; Dokoupil, Vladimír (referee) ; Omes, Jiří (advisor)
This thesis is focused on the construction of punching device for punching continuously extruded plastic profile. This device is part of a larger production line. The theoretical part of this work will be focused in an introduction to plastic extrusion, cutting, molding properties and market research with punched plastic profiles. The practical part will deal with the product description, production line and the structural design of the entire machine itself including calculations. Part of this work are also drawing of selected parts and a 3D model.

Hudeček, Jan ; Pavera, Michal (referee) ; Dvořák, Petr (advisor)
The submitted bachelor’s thesis are dealed with concept and design of holder of new palette, which is determine for deposition equipment, which belongs to institue of physical engineering and which is called as Kaufmann. Introductory chapters of bachelor’s thesis deals about possibilities of production of thin films, ways of growth of thin films and introduction to vakuum physics. Next chapter is given to current deposition and current deposition equipment Kaufmann. In the next chapter are descriptions of construct solution of holder of new palette and construct solution of palette. The last chapter is given to calibration and optimalization of deposition with new palette.

Improving and extending the multiple sequence alignment suite PRALINE
Hudeček, Jan ; Mráz, František (advisor) ; Petříčková, Zuzana (referee)
The aim of this work is to study potential improvements in the core routines of multiple sequence alignment suite PRALINE. A general overview of multiple sequence alignment methods used with emphasis on representation of the alignment core is given. A new option for aligning sequence profiles was implemented and its usefulness assessed. This option allows a user to input a profile which is used in an advanced phase of the progressive protocol as if it was a result of the previous steps. Two new protocols using profile Hidden Markov models (HMM) and their alignment were implemented and tested. The HMMGUIDE protocol creates for each sequence a preprofile consisting of segments of other sequences with high local similarity. HMM is generated from each preprofile by HMMER, and alignment of every pair is scored by PRC. The protocol then progressively aligns the sequence whose HMMs achieved the best score. The PRCALIGN protocol works similarly but aligns the sequences according to the best alignment of the HMMs. While not all test alignments were finished successfully for both protocols, the results constitute a statistically significant improvement over the original PRALINE protocol.

Software for a Czech-Chinese and Chinese-Czech dictionary
Hudeček, Jan ; Homola, Petr (advisor) ; Straňák, Pavel (referee)
Czech-Chinese and Chinese-Czech dictionary is an electronic dictionary which can be used both by a beginner or a seasoned translator. It allows searching in both directions and a fulltext search for given expression. Data access is hybrid - the program checks if it can access the database - if it fails it reads the data files. Moreover users can change the data source at run-time. The program builds indexes on the data file speeding searches up considerably. Indexes can be hashtables or binary trees. Asynchronous multithreaded IO was implemented to enhance the comfort of the GUI. The .NET framework and MS SQL Server as a platform guarantees rapid development, deployment and scalability - for example adding a web application to the project would be quite easy. At the same time the design of the system allows for future improvements - for instance editing the dictionary from the GUI.

Dynamic Social Networks and their Analysis
Hudeček, Ján ; Mrázová, Iveta (advisor) ; Vomlelová, Marta (referee)
For a long time, there has been little research on dynamic social networks. However, in recent years, there has been much more focus on this field and many techniques for analyzing temporal aspects of social networks were proposed. In this work, we studied a dynamic social network based on data retrieved from the Commercial Register. This registry contains information about all economic entities that operate in the Czech Republic, including people who hold functions in entities and their addresses of living. We applied several data analysis techniques including community tracing, clustering, and methods for identifying key actors to find important entities and individuals in the social network and inspect their changes over time. 1
