Improving material flow by using a logistics train
Grepl, Radovan ; Urbanovský, Jan (referee) ; Zeizinger, Lukáš (advisor)
The main content of this master´s thesis is the analysis of the current state and the proposal an internal supply of assembly lines in the company Koyo Bearings s. r. o. This company specializes in the production of bearings mainly for the automotive industry. The supply of the lines operates on the principle of Mikl-run. The practical part focuses on creating a simulation model using the Plant Simulation simulation software from Siemens PLM Software. Based on the created model, several variants were proposed to optimize the loading of the packaging material. These variants were analyzed and evaluated.

Statistical inspection
Vyškovský, Jaroslav ; Fiala, Alois (referee) ; Pernikář, Jiří (advisor)
This work solving with the statistical inspection verification of big amounts of products imported to Czech Republic. Work it self is designed as general handbook and it will be possible to use it on other products then the model one. This work was elaborated with company which is importing screws for wood industry. We used common standards to define quality requirements of verificated products, and to design statistical inspection plans. The goal of this work is technical and economical evaluation of designed method, which was used on model product.

VBA and Maple application in process engineering problematics.
Farkač, Daniel ; Jegla, Zdeněk (referee) ; Kohoutek, Josef (advisor)
The task of the diploma thesis named VBA and Maple Application on Process Engineering Problems is to show the possibilities of using these programming languages for various engineering tasks. Particularly the programming language Visual Basic for Application (VBA), which is a part of MS Office package, is very little used in practise. That´s why this thesis solves the complex task of a furnaces design process; the topic was reccomended by the supervisor prof. Ing. Josef Kohoutek, CSc. Specifically, the thesis deals with calculations of heat transfer and optimization of the height of extended surfaces of tubes in the convection section of process furnaces. The entire task is elaborated in VBA and runs in Excel. After entering the input information, the created program first calculates the size and heat output of the convection section, but it can also optimize the height of extended surfaces in different parts of the convection section and thus minimize investment costs.

SIMULATION OF ENERGY PERFORMANCE AND REAL OPERATION OF BUILDINGS
Šteffek, Libor ; Ingeli,, Rastislav (referee) ; Hirš, Jiří (referee) ; Ostrý, Milan (advisor)
This dissertation thesis primarily focuses on the experimental measurement of energy consumption of a given energy-passive family house as well as theoretical research in the field of energy calculations using computer simulations. The results of quasi-stationary and dynamic simulations, with varying computational and real-time climate data, are compared with experimental measurements. Using the dynamic calculation model, which was validated by actually measured data, the relationship between architectural design and the energy performance of the building was analyzed. The influence of selected different operating modes for heat consumption on heating, cooling, ventilation, and interior overheating is observed. The result of the mutual interaction of several input parameters of variant solutions provides the basis for optimization of the whole design.

Mathematical Models of Demand
Trzaskaliková, Eva ; Půža, Bedřich (referee) ; Mezník, Ivan (advisor)
The diploma thesis deals with the analyses of demand using standard tools of engineering mathematics. Mathematical models of demand, both single and multi- factor are investigated. Elasticity of demand is applied for decision making in price policy. Problems of optimization of demand reflecting utility and budget constraints are under consideration. Constructions of demand curve and compensated demand curve are presented. The text is accompanied by illustrative examples aiming at methodical aspects of the work

Electrochemical analytical devices for thick-film sensors measurement
Pytlíček, Zdeněk ; Adámek, Martin (referee) ; Prášek, Jan (advisor)
This work covers an area of electrochemical analytical systems for trace determination of dissolved species in water solutions with use of thick-film sensors. Several types of common electrochemical devices including special ones used for sensors are described and compared in this work. The main goal of this work is to find the suitable electrochemical arrangement with the best, reliable and reproducible current response of the thick film sensors. A new electrochemical arrangement, which should eliminate disadvantages of common devices and unite their advantages with optimization for thick film sensors, is designed here. For better current response of the sensor, suitable improvements and optimization of the new electrochemical arrangement prototype were done in this work. All measurements were done on standard electrochemical couple of potassium ferro-ferricyanide using the cyclic voltammetry. In the end of this work, all the devices are compared in term of their features and presumptions for the best detection limit of the thick film sensors.
