Optimization of the permanent magnet machine based on the artificial inteligence
Kurfűrst, Jiří ; Duroň,, Jiří (referee) ; Singule, Vladislav (referee) ; Ondrůšek, Čestmír (advisor)
The dissertation thesis deal with the design and the optimization of the permanent magnet synchronous machine (SMPM) based on the artificial intelligence. The main target is to apply potential optimization methods on the design procedure of the machine and evaluate the effectiveness of optimization and the optimization usefulness. In general, the optimization of the material properties (NdFeB or SmCo), the efficiency maximization with given nominal input parameters, the cogging torque elimination are proposed. Moreover, the magnet shape optimization, shape of the air gap and the shape of slots were also performed. The well known Genetic algorithm and Self-Organizing migrating algorithm produced in Czech were presented and applied on the particular optimization issues. The basic principles (iterations) and definitions (penalty function and cost function) of proposed algorithms are demonstrated on the examples. The results of the vibration generator optimization (VG) with given power 7mW (0.1g acceleration) and the results of the SMPM 1,1kW (6 krpm) optimization are practically evaluated in the collaboration with industry. Proposed methods are useful for the optimization of PM machines and they are further theoretically applied on the low speed machine (10 krpm) optimization and high speed machine (120 krpm) optimization.

Examples of governings with predictive controls
Šalda, Zbyněk ; Švarc, Ivan (referee) ; Němec, Zdeněk (advisor)
This thesis deals with model predictive control principally Based Predictive Control (MPC). The first part describes the principle of predictive control, cost function, the choice of a constraints in regulation and the choice of weights. In the next section is an analysis system: a system with non-minimal phase (control water turbine), oscillating systems (trolley frame control) and system with a time-delay . In all of these systems is performed classical feedback control using PID control and concurrently regulation with the MPC. MPC is selected as the solution fy Mathworks Model Predictive Control Toolbox and Simulink. The results are then analyzed using the criteria of quality control.

Economic analysis
Pokorný, Martin ; Boukal, Petr (advisor) ; Štamfestová, Petra (referee)
The aim of the thesis is to describe the purpose, content and methods of economic analysis in the theoretical part. The application part continues by application of the theoretical findings to financial statements of ITW PRONOVIA, s.r.o. company of years 2009 to 2014. The most important elements are horizontal and vertical analysis, ratio indicators, DuPont analysis, working-capital analysis, economic value added (EVA), Value and Bankruptcy models and labor productivity analysis.

Determination of the cost function in a company and its possibile applications
KUBÍK, Tomáš
This bachelor thesis is oriented primarily on the classification of costs in a company and the de-scription of suitable methods for construction of the cost function. The theoretical part of the thesis describes financial and managerial concept of costs and the difference between them. Possibilities of the records of costs and different approaches to distribution of the costs are dealt with here. This part also explains the principle of method determination of the cost function. The practical part of this thesis is focused on the classification of costs in a company which produces paper boxes. On the basis of this apportionment, specific methods for the determina-tion of cost function are selected. These methods are used to construct the cost function in this company. The aim is to assess the contribution of the cost function to a better cost manage-ment. Cost function was constructed by 4 methods (classification analysis, method two periods, graphical method, regression and correlation analysis). Regression and correlation analysis is the most accurate method, because it eliminates subjectivity This method counted regression pa-rameters b0 5 738 590 and b1 4,97. The shape of cost function is also TC = 5 738 590 + 4,97 × q. The break even point was counted by this method in value 6 865 711 squares and company must produce 7 563 617 squares for production profit 7 000 000 Crowns. The company can use this cost function for more efficient cost management and for the optimization of its production capacity.

Controlling in company Llentab
Zemanová, Tereza ; Mikovcová, Hana (advisor) ; Koucká, Jana (referee)
This Diploma thesis aims to theoretically define tools used by modern controlling and then practically apply them in specific company in Czech Republic. To analyse the chosen company will be used both strategic and operational controlling instruments. Calculations and analysis will help the company to understand the environment in which they operate and which is their current position. Finally I formulate opinions and recommendations about the currently used procedures in the company.
