Design and lay-out of high pressure pumping station.
Václavík, Tomáš ; Franc, Zdeněk (referee) ; Habán, Vladimír (advisor)
The aim of diploma thesis is design and lay-out of high pressure pumping station with plunger pumps for splash of scales from slabs of hot-rolled. Theoretic (introduction) part of this thesis contain description of formation of scales and description of ways how it is possible remove these scales. And this part contains also explication of effect of water jet on solid material. The practical part of diploma thesis is focused on design of pumping station including of dimensioning of machinery. Part of this work is also technical documentation for proposed pumping station and specification of main machines and devices.

Optimalization of Induction Furnace Operation in foundry Vsetín
Trachta, Jiří ; Nowak, Stanislav (referee) ; Lázničková, Ilona (advisor)
The aim of this work is optimalisation of induction furnace in foundry for company PROMET FOUNDRY a.s. The company has two induction furnances. There are installed as identical construction. They have 2 modes of operation. First mode is founding and second mode is mode, where is temperature in maintain mode. Only one induction furnance can work in the founding mode at a time though. Inducion furnances are in the single-phase connection and they cause unbalance in the distribution network. Near the foundry there is a small network area whitch it is operated by company Zásobování teplem Vsetín a.s. The consumption of electrical energy in foundry so big, that in the year 2009 was made elaborate for Zásobování teplem Vsetín a.s. It was write at Laboratoře diagnostiky výkonů (Laboratory of performance diagnostics), which is a part of Electrotechnic Department at Technical Univarsity of Ostrava. The ordered study was named “Verification of causes of increased reactive energy consumption during transition from electricity delivery to electricity consumption”. The conclusion of this assignment confirms that in distribution network in the Jiráskova area in Vsetín there is unbalance of electrical energy and there is high part of reactive power. The next conclusion is crucial to find the customer who made the unbalance and to set relevant remedy. The last step will be the identification whether such device can actually be effectively balanced. It was subsequently proved that the Promet Foundry was causing the unbalance and that balanced consumption would be reasonable. Promet Foundry thus addressed Autel a.s. company with an inquiry to make a study of removing the causes of the unbalance which is caused by current induction furnaces operation at a minimum possible cost, least possible influence on the performance and minimum construction changes concerning the building. In this thesis there will be some topics. The result of which will be introducing of used heating technology, introducing of company and of effective plant performance and subsequent suggestions of possible unbalance removal or reactive power decrease. Several ways which are being implemented in the industry in order to balance consumption will be described. A suitable balancing plant will be subsequently chosen and its parameters will be calculated.

Risk analysis in conformity assesment process
Možný, Radek ; Teš, Vasilij (referee) ; Koška, Petr (advisor)
When presenting a product within the so-called regulated sphere the producer is obliged to keep to the given legal liabilities of the technical product requirements and the governmental regulations concerned. The producer is also to carry out an analysis of the technical requirements and specifications of the product. Subsequently, the producer also has to provide the technical specifications and documentation for preparation of ES declaration, guaranteeing that the product fulfills the CE requirements. The task is to design and set up documentation for the ES declaration for Polymount printer cleaning machines PPC mini, PPC M2, PPC L2 and PPC XL2.

Automated calibration of instruments with PC
Obšilová, Lucie ; Kapinus, Tomáš (referee) ; Havlíková, Marie (advisor)
Bachelor´s thesis deals with the automated calibration of measuring instruments. Theoretical part presents the program Caliber and the most common communication interface. Practical part describes the creation of instrument cards and the calibration procedures to calibrate the power meter Chroma 66202 and the electronic load Chroma 63103A. In the next part of the thesis, there is the calculation of uncertainty for one calibration point of each calibration and the verification of the correctness of the program. The last part contains the evaluation of differences between performing the calibration using the program and manual execution.

Process Calibrator M143 - Climatic Testing
Dojava, Václav ; Bartoň, Jan (referee) ; Havlíková, Marie (advisor)
Subject of the bachelor thesis are the climatic testing of the M143 calibrator. Theoretical section of the thesis is concerned with the analysis and description of the norms used during climatic tests of electronic devices. Thesis then continues by describing properties and functions of the M143 calibrator and the Caliber programme, which is performing automated measurement during the climatic tests, on the basis of the designed calibration procedure. Practical section of the thesis describes the designed testing points and climatic conditions, which are adjusted during the testing. In this section the testing points are implemented to the Caliber programme. Last section contains the analysis and evaluation of the measured data gained during the climatic testing. From these measured data, we are to determine, whether the M143 calibrator is within the specifications stated by the manufacturer in different climatic conditions.

Specifications Database of Security Protocols
Papež, Zdeněk ; Trchalík, Roman (referee) ; Očenášek, Pavel (advisor)
This bachelor's thesis is about the security protocols which are necessary for safe communication in the Internet. There are various kinds of security protocols in use but this work covers only selection of most important of them. I have tried to gather all available information and work them out into uniform database which can be used for further processing. In my opinion, main aid of this work is precise description of knowledge baseand prediction base of each protocol. Also all possible conditions and states are described. The end of part of this work sums up all concerned protocols into a user-friendly table which is used in web-side database accessible from the Internet.
