Information System of Paints Seller
Křenek, Tomáš ; Burget, Radek (referee) ; Bartík, Vladimír (advisor)
The aim of the thesis was to create a design and to implement an information system for paint surface treatment sellers. Implementation is carried out in the form of a web application in PHP using the Laravel framework. Simplicity and user-friendly design were emphasized due the system being used in a corporate environment. The main function of the system is order management, adding products to respective orders and selecting product packaging. Employees have the ability to view order dates in their Google Calendar client. The system also includes reporting sales statistics. Customers are advised goods based on processing of association rules.

Audio and video streaming using real-time protocol
Křenek, Tomáš ; Schimmel, Jiří (referee) ; Burget, Radim (advisor)
This diploma thesis focus on transmiting multimedia over computer network. There are detailed informations about protocols RTP and RTPC in a first part because a transmition over a network is realized by using these protocols. Some basic multimedia terms, FFmpeg codecs and SDL library are described in next chapters. A multimedia player using FFmpeg and SDL is implemented in a second part of thesis. The player is console application and it has basic user interface. The player reproduces video and audio from a given file. RTP communication is described in next chapters of the second part. RTP server and client are implemented there too. They are console aplications and they use data coded by Theora or Vorbis. There are summarized results in a conclusion.

Reconstruction of the Hranice weir
Křenek, Tomáš ; Uhmannová, Hana (referee) ; Julínek, Tomáš (advisor)
The bachelor´s thesis is the modification of the existing weir structure in Hranice on the river Becva at river kilometer 38,300. The first part is a search dealing with the topic of weir structures. In the second part, the locality of interest is first described. Then there is a mention of the historical development riverbed of the Becva and the original fixed weir, which goes on to describe the existing weir structure. Subsequently, the individual reconstruction proposals were evaluated and the most suitable variant was selected, including the choice of the type of substructure construction, movable valve and the fish pass. Last but not least, hydrotechnical calculations were performed, witch also contain a partial calculation of the stability of the proposed structure.

Gated weir design
Křenek, Tomáš ; Hadaš, Zdeněk (referee) ; Julínek, Tomáš (advisor)
The diploma thesis deals with the design of a new weir structure in Valašské Meziříčí on the Rožnovská Bečva river at chainage km 3,025. In the first part of thesis, a overview of the considered weir constructions and calculation equations to be used in the practical part are summarized. In the second part, the work firstly deals with the localization and description of the object of interest and then continues with the conceptual proposal of several variants of the weir structure and then with selection of most suitable solution of the new structure. For the selected variants, hydrotechnical calculations were done, which also include a partial calculation of the stability of the proposed structure. At the end of the work there is a technical description of the aims proposed objects and an evaluation of the set goals of the work.

IR Laser CVD OF Nanodisperse Ge-Si-Sn Alloys Obtained by Dielectric Breakdown of GeH4/SiH4/SnH4 Mixtures
Křenek, Tomáš ; Bezdička, Petr ; Murafa, Nataliya ; Šubrt, Jan ; Pola, Josef
Nowadays, great attention is devoted to Ge-Si-Sn ternary system, because Si1-x-yGexSny provides the potential of band gap engineering and tuning of the optical properties. IR laser irradiation of equimolar gaseous GeH4 + SiH4 + SnH4 + Ar mixture results in simultaneous decomposition of all three compounds and it allows deposition of nanostructured solid film. Analysis of the films by FTIR and Raman spectroscopy, X-ray diffraction analysis and electron microscopy revealed crystalline nanobodies of pure beta-Sn and crystalline nanoobjects of Ge1-x-ySixSny embedded in an amorphous metastable Ge-Si-Sn alloy. This process allows co-decomposition of all silicon, germanium and tin hydrides which is caused by combination of infrared multiple photon dissociation of absorbing silane and currently proceeding LIDB. This is followed by intermixing/clustering of extruded metal atoms in the gas phase.
