Evaluation of Polymer Separation System Purifier N 1024 device efficiency
Duliková, Michaela ; Charvátová,, Michaela (referee) ; Čáslavský, Josef (advisor)
In this Diploma Thesis the recycling of the PET bottles in the company PETKA CZ, a.s. is under focus. Thesis describes the Italian technology AMUT designed for physical recycling of the PET bottles. The primary goal is the quality of the final recycled product, PET flakes, particularly in the context of undesirable admixtures such as PVC, other polymers and impurities. Due to the deteriorating quality of the PET flakes the equipment Polymer Separation System Purifier N 1024 has been tested, which had significantly reduced admixtures in PET flakes. As it turned out, the current procedures for solving problems with the PET flakes quality are no longer sufficient.

Sorting algorithms
Schwarz, Jakub ; Smrž, Jaroslav (referee) ; Dvořák, Jiří (advisor)
Enormous volume of data, which has been processed during production operations, requires easy orientation and quick searching. Exact search in real time is essential for success. Correct and quick data-sorting is one of the most important activity during dataprocessing. The goal of this bachelor’s thesis is background research of sorting algorithms. To achieve the goal, basic concepts of sorting theory will be described (determined) and there will be division of sorting algorithms by different criterions. For each algorithm of internal array sorting, sorting principles will be described and analysis of efficiency will be provided. The results will be verified by experimental program.

Effective management of plastic waste
Kostková, Kateřina ; Pavlas, Martin (referee) ; Gregor, Jiří (advisor)
The main content of the submitted diploma thesis is the implementation of analysis of separated plastic waste and examination of the issue of extrusion tests. The practical knowledge is preceded by a search of waste management in the Czech Republic and get acquainted with the issue of polymer materials. The research is about plastic waste management and preparation of polymeric materials for extrusion tests. Theoretical knowledge is then applied in the practical implementation of extrusion tests.

Design of a paper waste container
Jančová, Petra ; Haltof, Vladimír (referee) ; Vespalec, Arnošt (advisor)
The aim of this work is to create a conceptual design of a paper recycling container with regard to aesthetic shaping, effective use of internal storage space, handling, transport and ergonomic requirements. It solves the shortcomings of current containers by timeless shaping using modern materials and reliable production technologies. The result is a practical container design that uses psychology to encourage the public to sort paper waste and thus contributes to environmental responsibility and sustainability.

Automatic Photo Sorting
Weiser, Michal ; Španěl, Michal (referee) ; Beran, Vítězslav (advisor)
The purpose of this article is to show how intuitive can be work with pictures sorting. Drag&drop technology in combination with interactive picture moving makes this application easy to use. To sort pictures with some feature you just must drag magnetic attractor into some place in workspace and choose attracting feature with specific value. Pictures with alike value are attracted. Difference in values determines the distance between picture and attractor. Combination of many attractors can help you sort pictures in short time with just couple of clicks.

Administration of development documetation over WWW II
Gregárek, Ondřej ; Sysel, Petr (referee) ; Balík, Miroslav (advisor)
Document server is a web application controllable by way of web browser. It is meant to serve for the management of development documentation. The application is divided to the four basic parts: Requirements, Products, Tests and Test Run. The section Requirements serves for inserting requirements for products. Product is produced on the basis of these needs and registered in part Products. Test setting is created in the part Tests according to requirements from the part Requirements. Particular products are then tested. The part Test Run registers records of these tests. These are parts of the application: management of users, connecting supplements to records, printing and exportation of data to different formats, saving history of records, filtration and sorting of entries, etc. All the data is saved in the database MySQL. The application is written in scripting language PHP. Data is presented by template system Smarty. The output is in language XHTML. Cascading style CSS is used to formatting. This work describes development of the application. First it is dealing with the proposal of the database, connection and structure of particular tables. The function of the programme is explained in detail at the same time, which is essential for the correct proposal of the database. The application is based on the database. The selected structure of files and relations of scripts to library functions are shown. The template system and the interface for access of the programme to the database are explained. The most attention is paid to the description of solving important functions of the application, i.e. listing of records, their pagination, filtration, sorting and operation with them: saving, browsing, copying, confirmation and work with history, category and problems by upkeep of consistent tree and export of data to various formats. It is always outlined the problem, the idea of solving and the description of appropriate scripts. Samples of source code are also included for better understanding of complicated algorithms.

Design of the copper cleaning equipment
Šmarda, Radek ; Pernica, Marek (referee) ; Lošák, Pavel (advisor)
The bachelor thesis has two main parts. First part contains methods of getting non-ferrous metals from waste and the second part is focused on designing device for copper purification from a predefined waste. At the end of the bachelor disertation are performed torsion shaft control, calculation of gear dimensions and shear test of parallel keys. There is attached drawing documentation to the bachelor thesis.

Uncoated cemented carbides
Benešovský, Radek ; Sedlák, Josef (referee) ; Humár, Anton (advisor)
This bachelor thesis deals with the uncoated cemented carbide used in the manufacture of cutting tools. There is an overview of the most frequently used tool materials in the first part. The second part describes history, sorting, labeling and physico-mechanical properties of uncoated cemented carbides. The last part is focused on products of Pramet Tools, Sandvik Coromant, Seco Tools, Ceratizit, Walter and Iscar and their comparison in terms of cutting speed.
