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.

Laboratory Tasks for Analogue Technology
Pavelka, Ondřej ; Haupt, Jaromír (oponent) ; Langerová, Petra (vedoucí práce)
Subject Analog Technology focuses on basic analogue functional blocks and their usage in modern electronic devices. Theoretical part of a particular topic is taught at lectures and laboratory exercises are used to demonstrate specific examples to strengthen student’s knowledge. This paper contains comprehensive manuals with measuring procedures for all compulsory laboratory tasks, for students, to better understand all topics discussed in the subject Analog Technology. These manuals include theory regarding certain topic, mandatory tasks for students, connection diagrams and in some cases, necessary math equations to calculate outcome values. To verify correctness of a working procedure and for clarity an oscilloscope will be utilized. These manuals also contain tables as attachments, which are prepared to be printed and filled in with calculated values that are the outcome of some laboratory tasks. The main purpose of this thesis is to enhance the level of knowledge of students attending the subject Analog Technology and to improve effectiveness of the work in laboratories.

The influence of mother tongue on learning foreign languages
Kimličková, Lenka ; Langerová, Petra (oponent) ; Smutný, Milan (vedoucí práce)
This thesis deals with the topic of the second language acquisition and relationship between the mother tongue and target language. It explains basic definitions regarding second language acquisition, contrastive analysis and language transfer. It stresses the importance of the first language acquisition and explains theories of SLA. It provides reader with examples of the most frequent errors in language learning. Furthermore, it discuses non-language factors and their influence on SLA.

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.

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.

Academic writing characteristics: a brief handbook for students.
Stránská, Michaela ; Langerová, Petra (oponent) ; Baumgartnerová, Alena (vedoucí práce)
This Bachelor thesis deals with academic writing. Probably all university students encounter academic writing at some point in their studies. However, some of them might have particular difficulties in writing academic texts. Thus, the aim of this thesis is not only to characterize academic writing but also to design a brief handbook for students that would help them to cope with these difficulties and simplify their work by providing useful tips. The concept of academic writing, its definition and thorough characteristics are described in the first part of the thesis. Different types of academic texts that students most commonly encounter during their studies and its brief characteristics are also mentioned in the first part. The second part consist of the brief handbook for students. The character of this handbook is aimed to be as practical as possible. The handbook is divided into several chapters that deal with various aspects of academic writing such as the language and style. Nevertheless, a significant part of the handbook is dedicated to the preparations for writing because it is as important as the writing process itself.

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.

Generation of Energy Using Renewable Resources
Vrbka, Martin ; Langerová, Petra (oponent) ; Froehling, Kenneth (vedoucí práce)
This Bachelor thesis focuses on the generation of electric energy using renewable resources. There are numerous factors related to renewable energy; however, these aspects are mostly looked upon individually rather than in a complex form. Therefore, the thesis attempts to cover most of the important aspects related to the generation of energy using renewable resources and organizes them into a logical form. This is done by presenting a general description of the technology itself as well as resulting impacts from utilised systems.
