Abstract:

In these days one of the global problem seems to be continuous population growth. The most quickly rising population can be found predictably in the poorest developing countries of the world, which also have trouble with meeting basic demands of its inhabitants. That is why it is necessary to closely watch population trend, because it noticeably influences many social-economic issues like sufficiency of work opportunity, access to the education, housing etc.. This diploma thesis focuses on monitoring of population development of Slovak republic till 2025. The aim of thesis is creation of simulative model in program SIMPROCESS 4.3.1, which will offer transparent results of population development forecast. These model results in program SIMPROCESS 4.3.1 are compared with official population development forecast in Slovakia till 2025 published by Statistical Office of Slovak republic in 2007. The thesis is focused in detail on monitoring of demographical indicators like birth rate, mortality rate and migration.

Abstract:

This master’s thesis deals with the design of a robotic cell for the automation of woodworking machine tending. The task of the robot is to manipulate with the specified laminated chipboards of various sizes, before and after machining. The boards are brought to the cell on pallets in three possible placement variants. After a brief research part, conceptual designs of cell layout were created. The optimal and further elaborated design came as a result of selected evaluation criteria. The next part of the thesis consists of designs and selection processes of individual components. These were later used to create a simulation model in Tecnomatix Process Simulate software (Siemens), that helped to verify the functionality of the cell layout, design the control logic and acquire the time of the manipulation cycle used for informative calculation of annual production. In the end, the final design was evaluated from an economic point of view with an emphasis on the return of the initial investment.

Abstract:

In this thesis, called a simulation model of population growth, there was created the simulation model of a population growth in the Czech Republic to the year 2052. First there was constructed the projection through the component method used in demography. Deterministic values obtained by this method are then used in the simulation analysis. In the simulation analysis there was conducted an experiment with three variables which influence the population growth (the fertility, life expectancy/the coefficient of the decline of the probability of the death/ and the migration balance). With the support of the Crystal Ball, supporting program for Excel, which provides the possibility of the simulations, there was determined the stochastic character of the three variables. There are created the low, medium and high variant of the projections, as well as three other possible variants of population growth that might occur. These variations are called economic crisis, friendly migration policy and restrictive migration policy.

Abstract:

First, this thesis introduces the system of pension insurance with state contribution including its proposed amendment made in 2009. Its aim is to forecast and to analyse expected development in pension insurance with state contribution. The main part of the thesis is focused on the simulation model of this insurance product. Within this model, annual interest on contributions is randomly generated and the amount of money a client of a hypothetical pension fund would receive is calculated. To facilitate this simulation, I programmed and attached (as a part of the thesis) an application in VBA language which enables to run this simulation in the preset number of replications. The thesis gives four examples of simulation experiments -- a simulation of pension insurance, and a simulation of pension saving, both versions both with and without contributions made by client's employer. The comparison of the expected efficiency of the both systems from the point of view of the government and a client is drawn at the end of the thesis.

Abstract:

The aim of this work was to propose an analytical spindle lathe and perform simulations to verify that the spindle is designed correctly. After calculations and modeling of the whole assembly, I began to make the first simulation in ADAMS. I proceeded from simple models over difficult to the final version of the entire assembly. I examined whether they match the values of power, speed, strength and other values with the values obtained analytically. The results of my works are virtual models of spindle, which can simulate various stressful conditions under which we can decide whether the spindle is satisfactory or not.

Abstract:

The master thesis deals with computational modeling of a turbocharger vibrations and and assessment of influnce of passive dynamic vibration absorber on vibrations of actuator bracket. The use of dynamic vibration absorber was summarized in the research study. The analysis were performed using finite element method in ANSYS. Several computational models of turbocharger were created with different ways of modeling bolted joints between turbocharger parts. Modal analysis of each model was performed and the results were compared. For the selected model, the response to the kinematic excitation from the internal combustion engine for two load conditions was calculated using harmonic analysis. A simple model of vibration dynamic absorber was applied to the turbocharger model with reduced degrees of freedom and its influnce on vibrations of actuator bracket was investigated. Significant decrease of the maximum acceleration amplitude was achieved in a given frequency range when absorber parameters were optimized.

Models are created for motor with permanent magnets and for motor with wound rotor. The models are designed to enable simulation with both different longitudinal and transverse inductance, thus with salient rotor and non-salient rotor. The models can also be powered directly from three-phase sinusoidal source or a simple vector control can be used for their acceleration. All models are aligned so that their parameters can be set in only one m-file. Furthermore, automatic generation of phasor diagrams for steady-state motor, which serves as an interactive tool in class, is also created.

Abstract:

In recent years, the project management is very popular tool for management of companies and their processes, and this system is utilized in companies of practically any specialisation. In this diploma paper the principles of the project management are applied on a real construction project, which is one of the most common applications. During project preparation, another two disciplines of the operations research are applied on the precarious parts of the project; namely simulation modelling, and optimization via mathematical programming. Simulation modelling allows the analyst to predict behaviour of the modelled real system without the need for any time or costs to be spent on its observation. In this paper the simulation covers the system of vertical transport during execution of the project. Optimization is meant to set such parameters of any model in order for the watched criteria to reach optimal values. In this paper, the optimization is applied on total budget of the project to minimize the total costs.

Na základe odvodenej teórie je vytvorený simulačný model, ktorý je vhodný na predikciu priebehu tlaku v komorách valčekového hydrogenerátora, síl pôsobiacich na valček a na predikciu vnútorných únikov vzniknutých skratovaním rozvodovej dosky, ktoré majú priamy vplyv na objemovú účinnosť valčekového hydrogenerátora. Simulačný model bol úspešne použitý pre optimalizáciu rozvodových dosiek valčekového hydrogenerátora a vhodnosť simulačného modelu potvrdili následné merania Práca obsahuje aj analýzu síl pôsobiacich na vodiaci prstenec, ktorej výsledky boli taktiež potvrdené meraním. Analýza týchto síl môže vylepšiť v konečnom dôsledku parametre budúcich tlakových regulácii. Práca ďalej obsahuje základné porovnanie použitých tlakových regulácii. Všetky uskutočnené merania potvrdili, že valčekový hydrogenerátor s premenlivým geometrickým objemom s testovanými tlakovými reguláciami je schopný úspešne pracovať v hydrostatickej prevodovke. Druhá časť práce analyzuje potenciál výkonových úspor valčekového hydrogenerátora s premenlivým geometrickým objemom pre dve mobilné aplikácie - teleskopický nakladač s hmotnosťou 9 ton a kombajn s hmotnosťou 20 ton. Analýza vyžaduje jednorozmerný simulačný model hydrostatického pohonu s teplotnou predikciou hydrostatickej prevodovky. Dva rozdielne koncepty variabilného doplňovacieho systému hydrostatickej prevodovky sú porovnané so štandardným doplňovacím systémom pre pracovný a transportný režim oboch vybraných typov vozidiel. Simulácia pohonu vozidla s valčekovým hydrogenerátorom s premenlivým geometrickým objemom vo funkcii doplňovacieho hydrogenerátora a obtokovou clonou potvrdili vyššie úspory iba v prípadoch, kedy rýchlosť doplňovacieho hydrogenerátora bola výrazne vyššia a prietok cez obtokovú clonu do skrine hlavného hydrogenerátora zabezpečil dostatočné chladenie. Najvyššie výkonové úspory boli dosiahnuté s premenlivým preplachovacím systémom, ktorého prietok sa menil podľa požiadaviek hydrostatickej prevodovky. Záver druhej časti práce sa zaoberá metodikou dimenzovania veľkosti doplňovacieho hydrogenerátora.

Abstract:

The issue of an aging population, pension systems and pension themselves, are currently very actual, interesting and socially topics discussed. In my diploma thesis on simulation models of pension insurance due to demographic development in the CR I used simulation experiments, including those based primarily on the Monte Carlo method, tackling issues and negatives surrounding pension insurance with state contribution, which, as one of the financial products market, is the second pillar of pension system in the Czech Republic. Pension scheme of pension insurekce with state contibution gives participants the advantages and benefits in the form of state subsidy, the possibility of reducing the income tax base on the part of the contributions paid, proceeds from fund management and the possibility of contributions from the employer. On the other hand, play an important role, weaknesses and shortcomings of this system. Again, the most important may be considered inseparateness fund's assets from an estate participants, inappropriately designed state contribution, the high average age of participants and relatively low rate of return on fund management. Negatives mentioned above were reflected in the simulation experiments, when the linear state contribution was designed and was considered for the new system of pension saving in combination with a linear state contribution, which appears to be a more appropriate and beneficial for both participants on the one hand, and the state (impact on public spendings) on the other.

Abstract:

The dissertation thesis with the topic „Simulation Modelling of Electrical Drives for Selected Critical Applications“ focuses on the area of given applications in civil aviation. The selected application that the thesis deals with is an electrically driven and electronically controlled fuel pump supplying fuel to an aviation motor of the APU type. The thesis gives a comprehensive description of the design cycle of the unit and demonstrates implementing all the required critical functions. In the course of the design of the unit modern techniques in mathematical modelling, simulation, verification, monitoring and prediction of the operation status of airborne equipment were uses to the utmost extent. The purpose of these was to show the suitability of their application with regard to decreasing design time and cost, increasing lifetime and servicing intervals, as well as increasing user comfort and decreasing price. At the same time the required reliability was to be kept. The thesis also aims to prove and verify the suitability of using electronically commutated dc motors in critical applications in civil aviation. To reach this goal, it is necessary to design a robust drive control which would meet the given reliability requirements.

The aim of my diploma is to introduce the SNMP protocol designed for remote device management to the readers and present its implementation into the Opnet Modeler simulation environment. For the implementation the DiffServMIB database has been chosen, which describes the components of differentiated services mechanism. My diploma thesis describes in detail the possibilities of application of the DiffServMIB database in traffic management. The design of a simulation model, which represents the differentiated data processing in input and output direction on a router interface, is also introduced. Next, this model is implemented into the Opnet Modeler simulation environment. The goal of this simulation model is the possibility of simple configuration of individual MIB attributes. In my work I also suggest an implementation method able to interconnect the MIB database with the configuration process of the active network element - with focus on output procedures of DiffServ mechanism.
