Mathematical Modeling of Company Efficiency Using Neural Networks in Maple
Bartulec, Tomasz ; Vašátko, Jiří (referee) ; Chvátalová, Zuzana (advisor)
The goal of this thesis is to study the possibilities of Artificial neural network as an innovative mathematical methods for financial analysis of company performance, to find out what are today´s requests for performance evaluation of companies are and to identify possible ways how to use this relatively new concept in this area. When processing the possibilities of the computer program Maple for mathematical calculations will be applied. Intermediate objectives are then acquainted with the basic principle on which the artificial neural networks works, to analyze the financial performance of specific company and evaluate potential predictive abilities of the proposed network. The result of the work should be evaluating the success of this approach to financial analysis and evaluation of its use in practice.

Game of Markets
Dóczy, Aneta ; Novotná, Veronika (referee) ; Chvátalová, Zuzana (advisor)
This diploma thesis deals with conict economic situations based on game theory. In the beginning, basic models of conict situations and current popular software tools are dened not only for the general support of student education or for science, but also for solving economic problems in game theory. Based on this analysis, the conicting situation of two competing rms is being solved. Gradually, work goes deeper into areas of delay dierential equations that better show the behavior of two players on the market. Subsequently, these delayed dierential equations are projected into the Cournot model, for which a critical value is identied that switches the stability of two rms on the market due to the delayed realization of their outputs.

Heat exchanger for rescue habitat
Bouma, Adam ; Kilkovský, Bohuslav (referee) ; Jegla, Zdeněk (advisor)
This thesis deals with the specific issues of designing a suitable type of heat exchanger for ventilation in a rescue habitat. The paper presents an overview of the most common types of heat exchangers and characterizes basic heat transfer mechanisms (radiation, convection). Based on the above and other knowledge, a thermal-hydraulic calculation model suitable for a regenerative heat exchanger type is compiled and the necessary calculations are performed. The thesis also contains an evaluation of the results for three materials which can be used in the production of a heat exchanger (aluminum, copper, steel).

Applications of Selected Quantitative Methods for Financial Analysis of Company Operating both e-shop and Store
Zlevor, Karel ; Hanušová, Helena (referee) ; Chvátalová, Zuzana (advisor)
The aim of this thesis is to analyse financial situation of a company using the main principes of financial analysis and selected quantitative methods. The main sources for data collection were accounting statements – profit and loss statement and balance sheet. The regression analysis has been undertaken in order to prognose time development of selected indicators. Final calculations and visualisation of the figures are presented in MS Excel and Maple softwares. In addition the present paper includes interpretations of the outcomes and recommendations fot further financial development of the company.

Stress-strain analysis of the Gbely drilling tower
Vizváry, Peter ; Kovář, Jaroslav (referee) ; Fuis, Vladimír (advisor)
The content of the bachelor's thesis is focused on the stress-strain analysis of a drilling tower located in Gbely. Its main goal is to compile equations of static equilibrium for the analytical solution of the structure and its subsequent numerical verification using the created 3D computational model based on various static loads or changes in the degree of static determinacy. The first part of this work summarizes the theory of the bar and of bar systems, the basic limit states and the finite element method (FEM). The second part contains a search on the history of oil production in Slovakia, its discoverer and the development of deep drilling and production technologies. The third part describes the drilling tower in Gbely. The content of the fourth part is the creation of a 3D computational model of a real structure, which should represent the drilling tower as accurately as possible. The most comprehensive is the fifth part, which consists of the design of a simplified structure, writing the equations of static equilibrium for the analytical solution, creating a 3D computational model for numerical verification of the analytical solution and evaluating the conclusions to which the individual variants of the solution led.

Semi-Analytical Computations
Herzallah, Ahmad Sudqi Hussein ; Kopřiva, Jan (referee) ; Kunovský, Jiří (advisor)
This thesis discusses the analytical errors emerging from semi-analytical calculations. It also discusses about the modern method of Taylor's series for numerical calculations of ordinary differential equations and chosen methods of charachterized functions. The end solutions indicate favourable results for the semi-analytical calculations in the selected roles and responsible differential equations by direct execution of Taylor's series for solutions of polynomial functions, exponential functions & geometric functions using simulation program "TKSL". It also discusses about the definite & indefinite Intergals and methods for the solution of definite integrals. Followed by a brief introduction of Maple, Matlab & TKSL and further comparison of the result of the three programs & finding the best way of resolving the definite integrals.

CMOS VLSI Circuits Simulation
Šťastná, Hilda ; Kocina, Filip (referee) ; Šátek, Václav (advisor)
This diploma thesis deals with processes of electrical circuits calculations in the last years' worldwide standards like Dymola, MATLAB, Maple or SPICE applications. Circuits calculations are linked with methods for solving linear differential equations, used in this work also by verification of functionality of designed models for CMOS inverter, CMOS NAND, CMOS NOR. Numerical integration method in combination with Taylor series is a suitable method also for parallel calculations of CMOS VLSI circuits. CMOS circuits simulation was implemented with this method in applications in MATLAB language, solving circuits, represented by differential equations. Functionality of the applications was verified by some real examples. Significant acceleration of calculations using Taylor series compared to other methods is an important factor in choosing methods used in circuit simulations.

Linear Programming Used as an Effective Weapon by Manager
Zaoralová, Hana ; Havlíček, Radomír (referee) ; Chvátalová, Zuzana (advisor)
The Bachelor’s thesis is focused on the processes taking place in the firm and their optimization using linear programming. At the first part of thesis the theoretical background, basic concepts and methods are defined, thus become familiar with operational research. Then the current situation and subject of business of the company are analyzed. The analytical section will examine specific situation related to the process in the company, knowledge of linear programming will be applied and we will attempt to find out whether these mathematical discipline can be practically used also in nonmanufacturing company, that is primarily engaged in providing logistics. Finally, the results will be interpreted using the software Maple.
