Changes in body weight depending on circadian typology of adolescent girls during the year.
ROKOSOVÁ, Monika
This thesis deals with monitoring changes of body weight of adolescent girls at the age of 16 20 years old through one calendar year in the context of a season of the year and chronotypology of a personality. According to this typology the monitored people are divided into so called "larks", who are more active early in the morning and during the day and "owls" whose activity rises in the evening and at night. The theoretical part deals with circadian rhythms, their function, role in the life of an individual and also their disorders. It focuses on a developmental specification of adolescent girls, lifestyle in this period of life, changes of body weight and diet. Another part is the meaning of the sleep, its need and associated with good sleep habits and sleep hygiene. In the practical part there is described a methodology along with the results of the research and employment of this project in practice.

Analysis of co-creation phenomena in Czech republic
Toušová, Kateřina ; Postler, Milan (advisor) ; Hokrová, Eva (referee)
The aim of this master thesis is to analyze co-creation as a marketing strategy and its use in Czech republic. Diploma thesis is divided into two parts, theoretical and practical. Theoretical part evaluate marketing communication strategies, principles of market research and consumer behavior. Practical part explains co-creation phenomena and evaluate its position in czech marketing strategies. Thesis also contains market research focused on perception of co-creation in public and business sector and medial analysis. Further part describe agency Perfect Crowd and its co-creation projects. Thesis is concluded by reccomendation for the future, based on overall analysis.

The presence of a dead node in a distributed system
Ecler, Tomáš ; Škorpil, Vladislav (referee) ; Kenyeres, Martin (advisor)
This thesis deals with the distributed systems and the algorithms executed in these systems. The first part provides the theory relating to the mentioned topic as well as the mathematical tools used to model the functionality of a distributed system in which a dead node is present. The practical part is focused on an analysis of the impact of a dead node presence on the behavior of the Push-sum protocol. The simulations were executed on a tree, a ring, a star and a fully-connected mesh topology in Matlab.

Trends in promotion and distribution of musical works
Šťáva, Zdeněk ; Riedlbauch, Václav (advisor) ; Müllerová, Jana (referee)
This thesis is devoted to an analysis of trends in promotion and distribution of musical works. The theoretical part of the thesis deals with the marketing mix, customer behavior, the definition of creative industries and copyright protection. The practical part describes the history and development of the music industry and the structure of music label, presentation opportunities, promotion and distribution of music recordings and music groups. The work also includes marketing research dealing with the sale of music recordings in the Czech Republic. Based on the results of research and analysis of other data it is trying to predict trends in the music industry. The aim of the work is the formulation of specific recommendations on how musical recordings offer to target customers and to refute some claims about transfer music recordings to the edge of the interests of consumers.

A Language for Description of Instruction Sets
Forejtník, Jan ; Charvát, Lukáš (referee) ; Smrčka, Aleš (advisor)
This bachelor's thesis introduces a simple concept of a language for description of microprocessor architecture, namely the instruction set. An interpreter of the language capable of simulating the behavior of the architecture is briefly described. This text may also serve as a manual for using the interpreter.

Impulse generator
Buš, Ondřej ; Drexler, Petr (referee) ; Kubásek, Radek (advisor)
This thesis deals with the question of generating very short voltage impulses. At first it considers the most used behaviors of impulses and their mathematical description. Then it covers various principial circuit connections, which are used for generating short impulses. There is a scheme of controlled generator described in detail in this work, which is being used for exciting the forming circuit. Part of this work is also a description of program equipment, scheme of connection with designed desk of printed circuit. Description of construction of three shape circuits based on theoretical findings follows. Every solution is compared to each other upon time and frequency domain.

Development of a linear stage actuator for UHV STM/AFM
Pavelec, Jiří ; Jiruše, Jaroslav (referee) ; Šikola, Tomáš (advisor)
The aim of this diploma thesis is to develop a linear positioning stage for Ultra High Vacuum (UHV) environment. Simple prototypes of the linear positioning stage were designed and incorporated as part of a multiaxis sample manipulator for a UHV Scanning Tunneling Microscopy / Atomic Force Microscopy (STM/AFM). Different types of position encoders and linear guideways are discussed. Implementation of the homodyne interferometer as an optimization tool for a slip-stick based linear stage is described. Scalar diffraction theory is used to model the diffraction grating optical position encoder behavior.

Conatimanation of vineyards soils by Cu
Kovářová, Lucie ; Mihaljevič, Martin (advisor) ; Komárek, Michael (referee)
The aim of this bachelor thesis is to resume existing knowledge regarding the contamination of vineyard soils with copper, which is mainly caused by a long-term application of Cu-based fungicides used to control wine downy mildew (Plasmopara viticola). The role of Cu as a trace element in the natural environment is discussed, as well as natural Cu contents in soils and in the Earth's crust. This manuscript is based on international scientific articles focusing on the above mentioned subject. The thesis discusses the problems of contamination of vineyard soils by Cu, deposition of Cu compounds into the soils, interaction of Cu with soil components and possible formation of mobile or immobile Cu soil forms, their behavior and factors influencing this behavior and possible environmental risks e.g. phytotoxicity, contamination of water bodies or contamination of fluvial sediments. Additionally, average Cu contents in agricultural soils in Europe and worldwide were compared with European and international guidelines and limits. Total Cu contents in some of the vineyards soils exceed legislative regulations and in case of further utilization of such soils, an additional analysis would be necessary. Key words: contamination, copper, vineyard soils, heavy metals

Thick-film sensors for heavy metals detection
Gajdoš, Libor ; Majzlíková, Petra (referee) ; Prášek, Jan (advisor)
This project describes the possibilities of heavy metals detections in solutions using differential pulse voltammetry with tree-electrode electrochemical thick-film sensors. In the theoretical part, the thick-film technology is described as well as thick-film pastes’ types and compositions, followed by introduction to electrochemistry and electro-analytical methods of measurement. This project also describes the three measured heavy metals – cadmium, lead and copper. In the practical part, heavy metals’ ions detection in solutions using carbon working electrode and determination of the detection limit and sensitivity are described and discussed. Finally the evaluation of obtained results and results comparison to hygienic limits are included.
