Mathematics for Electromagnetism
Rára, Michael ; Spousta, Jiří (referee) ; Doupovec, Miroslav (advisor)
The goal of this thesis is the description of elektromagnetism by means of selected parts of mathematics, in particular tensors, vector fields, integral calculus and integral theorems. Maxwell's equations will be derived by means of these notions in integral form, differential form and tensor form, we also show usefulness of tensor form of these equations.

Economic Curves
Hrubešová, Gabriela ; Doupovec, Miroslav (referee) ; Kureš, Miroslav (advisor)
The topic of this bachelor's thesis is to study some economic curves, a description of their attributes and a determining the mathematical expression. In the first part, it is explained the issues of general plane curves. Next part focuses on the characteristics of the most important economic curves and their use. The mathematical properties of the individual curves are described below. The last part is a software implementation in the program Wolfram Mathematica.

Tensors and their applications
Korbel, Filip ; Tomáš, Jiří (referee) ; Doupovec, Miroslav (advisor)
The goal of this thesis is to provide an overview of basic terms and results of tensor calculus. We introduce tensors as multilinear mappings and introduce basic tensor operations. In the next section, we give some examples of tensors, especially from the field of differential geometry.

Dynamics of Snake Robots
Kubiena, Jaromír ; Doupovec, Miroslav (referee) ; Návrat, Aleš (advisor)
In this thesis, we deal with the mathematical description of the kinematics and the dynamics of mechanical systems. Then we focus on the particular mechanical system which is the Square robot with four legs with active joints and passive wheels, which moves on horizontal plane. The kinematics of the mechanical system is described by the control matrix, then we use it to express the equations of motion. We compute the dynamics the robot by using Lagrange equations. We verify that the mechanical system is nonholonomic constrained and we verify controllability by using Lie bracket and distribution. We find the singular postures of the robot.

Drozd rings
Nytra, Jan ; Doupovec, Miroslav (referee) ; Kureš, Miroslav (advisor)
This thesis focuses on Drozd rings. In the beginning, we mention important parts of algebraic theory for the definition of these rings. In the next chapter we describe an example of Drozd ring. In the following, we concentrate on Weil algebras - it shows up, that Drozd algebras over field of real numbers are specific examples of Weil algebras. We also construct groups of algebra automorphisms for these algebras. In the last part of the thesis, we mention Lie groups, because groups of algebra automorphisms of Weil algebras are examples of Lie groups.

Geodesics
Čambalová, Kateřina ; Tomáš, Jiří (referee) ; Doupovec, Miroslav (advisor)
The goal of the thesis is to create an overivew of geodesics. At the beginning of their study, they were considered shortest paths connecting two points on surfaces. In the thesis we will show more of the complexity of the term and introduced the properties, some uses of the geodesics and methods of their computation. Later, the Clairaut patches and their geodesics will be analysed. Clairaut patches are characterized by a specific property which makes computation of geodesics simpler. 3D plots of some Clairaut patches and their geodesics are also included.
