Practical applications of superconductivity
Mádrová, Tereza ; Langerová, Petra (oponent) ; Baumgartnerová, Alena (vedoucí práce)
This bachelor’s thesis is focused on the elaboration of a summary overview of the use of superconductivity in technical solutions and applications, which means not experimental use, but use in a real technical solution. This work deals with the description of basic superconductivity attributes in the first part (without which the principle of superconductivity cannot be fully understood and therefore description of superconductivity is a necessary part thesis), in the second part of the division of superconductors and superconducting categories according to specific criteria is described, and the last part of this thesis states examples of applications of superconductivity as we can encounter them in everyday life.

Advanced systems of Li-Ion accumulators
Lexová, Kristýna ; Langerová, Petra (oponent) ; Mihai, Hana (vedoucí práce)
With the growing need for energy for portable electronics and electric vehicles, the issue of energy storage becomes increasingly important. This bachelor’s thesis provides an overview of electrochemical sources of energy, focusing on lithium-ion accumulators and the most commonly used cathode materials. It discusses the development of high-voltage cathode materials, including the system lithium-sulphur. The experimental part of this thesis describes the preparation of several cathode samples and compares their electrochemical properties.

From industrial robots to androids
Baďura, Martin ; Langerová, Petra (oponent) ; Šťastná, Dagmar (vedoucí práce)
This bachelor’s thesis is focused on the theme of robotics. In the theoretical part, it briefly introduces the term robot and then it describes history of robotics from the most primitive inventions to today’s androids. It mainly focuses on the most significant milestones throughout the history. The next part aids at the problematics of sociable robots. It describes the aspects of sociable robots and deals with various design and ethical issues associated with the construction of a sociable robot. The last part deals with legal and ethical problems according to the European Parliament. In the practical part, results of the questionnaire survey are presented.

Measurement in Electrical Engineering – Digital Learning Materials
Ondráčková, Michaela ; Langerová, Petra (oponent) ; Ellederová, Eva (vedoucí práce)
The aim of this bachelor thesis is to present theoretical background for creating Digital Learning Materials for subject “Measurement in Electrical Engineering”. The work focuses on the concept of digital learning materials and on the design methodology of digital learning materials. The thesis describes the learning requirements of the subject (“Measurement in Electrical Engineering”), necessary theoretical basis for creating didactic text and design requirements. Additionally, this bachelor thesis presents two designs of digital learning material, presentation and worksheet.

Technologies for storing electrical energy in electric vehicles
Zdražil, Marek ; Walek, Agata (oponent) ; Langerová, Petra (vedoucí práce)
This bachelors thesis is focused on technologies used for storing electric energy in electric vehicles. The first chapter deals with history of technologies for electric energy storing and their use in early electric vehicles. It continues by description of electric vehicles that were occasionally produced through the 20th century, up to 1990s when this technology became attractive again. The following chapter describes types of electric cars and gives us examples of currently produced cars. The third part deals with technologies used in present and recent past. Subsequently, in the last chapter, there are introduced technologies which might be sufficient substitution to current systems or even to conventional combustion engines in future.

Antennas from non-conventional materials
Sedlák, David ; Baumgartnerová, Alena (oponent) ; Langerová, Petra (vedoucí práce)
Production of alternative types of antennas is a very interesting sector of electro-industry, and many of the world's largest companies but mainly portable electronical devices producers are involved in. However, the development as in any industries is in process. All of the process described in this thesis is verified and tested. It has to be noted that there are many more procedures and processes which are not described in this thesis. Therefore, the thesis will deal with: Antenna types for wearable application, wire antennas, aperture antennas, conductive material coating, screen printing, inkjet printing, implementation of conductive fibre into textile, printed glass antenna and practical realization of the patch antenna.

Fast signal processing
Rychlý, Ivo ; Langerová, Petra (oponent) ; Mikulka, Jan (vedoucí práce)
An increasing amount of data in modern image processing requires a new approach in algorithms. The biggest obstacle for successful speed up of an algorithm is parallelization and subsequent optimization. Architectures like CUDA and OpenCL with modified programing languages and interfaces help to overcome this obstacle and bring parallel computing to a broader audience. In this paper I take a look at basics of image processing and how parallelization can speed up the algorithms in image processing.

LOSSES IN MEDIUM VOLTAGE CURRENT TRANSFORMERS
Bajánková, Denisa ; Langerová, Petra (oponent) ; Baumgartnerová, Alena (vedoucí práce)
The bachelor’s thesis is intended to provide insight into the current transformer losses phenomenon. Current instrument transformers represent very important part of electrical systems, they are used to transform measured currents to standard values that measuring and protection devices can handle. It is important to transform these currents with the highest accuracy. The theoretical part is focused on the description of the current instrument transformers and particularly on the transformer losses analysis. The practical part included in the ninth chapter describes laboratory measurement and aims to verify the theoretical knowledge.

Commented Translation of Technical Text
Mičková, Daniela ; Kotásek, Miroslav (oponent) ; Langerová, Petra (vedoucí práce)
This bachelor thesis deals with the translation of a didactic text from the electrical engineering field. The work aims to translate and analyze a didactic technical text and is divided into three main parts. The theoretical part introduces namely the characteristics of technical style and didactic style, types of translation procedures, translation transformation and the functional sentence perspective. The practical part presents an English translation of an excerpt taken from a university textbook and the analytic part aims presenting the problems that occurred during the translation process and the assessment of the characteristics of technical didactic style based on this translation analysis.
