Tool for Modelling and Simulation of Technologic Processes
Skydánek, Libor ; Zbořil, František (referee) ; Kočí, Radek (advisor)
This thesis focuses on the problem of technological process modelling and simulation. It is based on the realistic requirements of the Faculty of Mechanical Engineering, where they lacked an extensible and open simulation tool with the ability to model biomass processing. In this work we explain the main concepts in the field of (physical) chemistry, the systematic approach to process modelling and simulation and we discuss various problems of simulation methods. We also describe the differences between simulation and design specifications and give reasons for choosing the sequential modular approach. An important part of the work is aimed at the design of the simulation tool's architecture, where the main emphasis is laid on the extensibility of future application. The tool has been implemented and it is now sucessfully being used at the Faculty of Mechanical Engineering.

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.

Pragmatic and didactic analysis of the topic of balance sheet for business academies
Kosíková, Iveta ; Fišerová, Marie (advisor) ; Berková, Kateřina (referee)
The bachelor thesis deals with the pragmatic and didactic analysis of the topic of balance sheet in the first concentric circle for business academies. Goal of the thesis is ascertainment level of knowledge of balance sheet of students of secondary, third and fourth class by anonymous tests in selected business academies. Main aim of the thesis was to create a teaching material for development of knowledge, which is based on results of the anonymous tests. Education of balance sheet should not be finished by teaching only related thematic unit, on the contrary, it should allow to be able to get back to it once necessary. Teaching material is created with the relevant idea. The balance sheet constitutes the core of accounting and for that reason balance sheet should be embodied in further thematic units. For students it is necessary to orientate in the balance sheet, to be able use the information and understand its meaning.
