Real Time Dynamic System Control
Veigend, Petr ; Šátek, Václav (referee) ; Kunovský, Jiří (advisor)
This thesis deals with the real time dynamic system control and it uses similar computation methods as earlier bachelor thesis. In the beginning of the thesis, some basics from the field of control and regulation are explained. Systems in this thesis are mostly described by differential equations. Because of this, thesis contains a section about solving differential equations. In this section, multiple approaches are covered and compared. The Modern Taylor series method is introduced, which is used by implemented applications. For system simulation, existing software was upgraded and multiple additional utilities were also implemented. The approximation of the transport delay is also mentioned. 
Autonomous Electronic Circuits Simulation Method
Minárik, Michal ; Konvalina, Jiří (referee) ; Kunovský, Jiří (advisor)
This work deals with a methodology of description of linear electrical circuits through the use of differential equations and autonomical method. It compares commom numerical methods with Taylor series method implemented in TKSL. It's focused on analysis of applicability of autonomical method to various circuits, complexity of circuit diagram transformation to system of equations and transcription to TKSL.

Kadák, Michal ; Pindryč, Milan (referee) ; Kunovský, Jiří (advisor)
This work deals with the possibilities of modeling electrical circuits and methods of solving these models. It focuses on the analysis of today's systems, so that their features can be used in our graphic editor design.
Mathematical modelling of the population dynamics of hemiparasitic plants
SVĚTLÍKOVÁ, Petra
The hemiparasite-host interaction is rather complex, acting as parasitism belowground and as competition for light aboveground. Studies modelling this interaction are rare. The most recent model of the hemiparasite-host interaction was developed from the well-known Rosenzweig-MacArthur predator-prey model by Fibich et al. (2010). Here, I modied the light availability function of the model into a more general form and examined the hemiparasite-host coexistence along a productivity gradient of the environment. The behaviour of presented and analyzed model was shown to depend particularly on parameter g scaling light availability for hemiparasites at high host biomasses. While it suggested the host-hemiparasite coexistence only at intermediate productivities under low g, species could coexist even at high productivities under higher g.
Differential equations with GeoGebra
OPAVOVÁ, Michaela
The main aim of this bachelor thesis called Differential equations with GeoGebra is to create a transparent collection of solved examples. Examples are numerically solved first, followed by their graphic interpretation by using mathematical program GeoGebra. Illustrations show us interesting solutions of examples. Another objective is to introduce students the program GeoGebra as a tool through which you can elegantly solve the example. The work is divided into three chapters, which deal with the basic type of differential equations, the method of separation of variables and linear differential equations with constant coefficients and zero right side. They are shown of the basic theory and then resolved examples. In These chapters are selected types of examples which meets student in Mathematical Analysis III. Therefore, this collection is useful as a study material for students of mathematical disciplines.
Periodic solutions of damped oscillations
HOLUB, Miroslav
The main topic of the Thesis is qualitative analysis of linear differential equations of second order. The Thesis is divided into five parts. At the first part there are explained basic type of oscillators (mathematical pendulum and spring). The second part is devoted to definitions and theorems, which are necessary in the study of differential equations. The third part shows the model of linear differential equation of second order. The solution of this equation depending on various parameters is indicated in the fourth part. Some open questions are formulated in the last part.

Počáteční chování bubliny páry v přehřáté kapalině
Vejražka, Jiří
The model is based on a simplified law for heat transfer of a growing and moving bubble and on solving the forces acting on this bubble. The model is represented by a system of ordinary differential equations and can be used until the time when bubbles start to wobble. An partially successful (but not convincing) attempt to validate this model by comparison with available experimental data was done. In most cases, the bubble behavior is controlled by a balance of the buoyancy with the added-mass force. In this aspect, the bubble behavior differs considerably from the case of constant-volume bubbles, for which the added-mass force is usually negligible. For the case of spherical bubbles, a simple analytical solutions are provided.
