Pricing of IT Goods
Kacina, Michal ; Janoušek, Vladimír (referee) ; Květoňová, Šárka (advisor)
The thesis contains the theoretical basis for study of possibilities of pricing information goods. The source areas are microeconomics, marketing, competitive advantage and economics of information goods. The model of market is created with constraints defined on the ground of theoretical basis. The thesis analyzes requirements that define the system that supports the choice of pricing strategy. It includes detailed design of the prototype of such system. The prototype is designed with robustness because of the future improvements. The design describes the prototype's input parameters and their transformation into useful outputs that cover basic characteristics of information goods. The designed prototype is implemented. The thesis includes demonstration of the prototype and possible directions for improvements that lead to validity of proposed model of market.

Optimisation of a part production for aircraft industry
Filipčík, Jiří ; Zouhar, Jan (referee) ; Píška, Miroslav (advisor)
This thesis deals with optimization of production of "Hold-down hinge hook" component, developed from difficult-to-cut titanium alloy Ti-6Al-4V. This work is focused on the material properties of the component, current research and optimization in titanium machinability sphere. Further it contains a part dedicated to the latest trends in development of cutting tools for machining of titanium alloys. This knowledge is furthermore used for the component production optimization in Frencken Brno s.r.o. company. This project continues with analysis of the component‘s current production technology and designs the way of elimination of production bottleneck. This change is presented by component‘s clamp jig, which decreases higher percentage of scrap due to the geometric complexity. This thesis further contains drawing and technological documentation needed for implementation of the improvement suggestions into the production. There was designed a new NC program. This project is accomplished with technical-economical evaluation.

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.

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.
