IoT system for factory energy consumption optimization
Čuhel, Radim ; Zeman, Václav (referee) ; Slavíček, Karel (advisor)
This work deals with the measurement of electricity consumption in the production plant Draka Kabely in Velké Meziříčí. The main solution to the problem in the theoretical part is a description of the general distribution of electricity in the Czech Republic, a description of the production plant and the measurement of electricity together with the principles of regulation of measured energy. The practical part of the work is focused on the implementation of measuring sensors in the corporate network model. Setting and commissioning of sensors together with the possibilities of regulating the consumed energy. The result of this work will be used to improve the regulation and use of electricity in the production plant.

Interdisciplinary research of medieval sacral architecture
Derner, Kryštof ; Havrlant, Jaroslav ; Křivánek, Roman ; Kuljavceva Hlavová, Jana ; Lissek, Petr ; Peksa, Vojtěch ; Skopec, Jaroslav ; Václavík, František R. ; Witan, Joanna ; Zeman, Václav
The methodology is divided into three basic areas of the cognitive process of sacral architecture, which differ according to the nature of the studied sources. I. Problems of knowledge of sacral architecture on the basis of written, cartographic and pictorial sources. II. Sacral architecture in terms of material sources of archaeological nature (artifacts, ecofacts and their finds). III. Sacral architecture on the basis of material sources of a building nature, examined by a building historical survey. These areas are accompanied by subchapters devoted to other methods, other cognitive and documentation processes. A necessary part are also small excursion chapters, in which specific examples from research practice are described.

Cardiorespiratory fitness of sporting population
Novák, Jaroslav ; Zeman, Václav (advisor) ; Votík, Jaromír (referee) ; Heller, Jan (referee)
Cardiorespiratory kapacity in sporting population J. Novák Summary VO2max and VO2max/kg values were directly obtained during 2777 measurements in competitive athletes and active but not competing subjects. The normatives of cardiorespiratory capacity for different age groups of male and female endurance athletes (Group A), team sport players (Group B) and other sports (group C) were established, and compared to normatives for Czech population based on the International Biological Program (IBP) results (Seliger a Bartůněk 1976). The most favorable values of cardiorespiratory capacity (both VO2max; VO2max/kg and W170;W170/kg) were found in the group A athletes (endurance trained) - both males and females. Their level highly exceeded the values of untrained CS IBP population and also those obtained in control group D in this study. The highest correlation was found between VO2max and Wmax and between VO2max/kg and Wmax/kg. This high correlation was very similarly high in the whole sample of 2777 examinations, in the sample of men (n=2015) and women (n=762) and also in all age-groups in different athletic groups A to D. It was proved that VO2max and VO2max/kg values could be calculated according to the maximal performance attained on bicycle ergometer. During spiroergometric examination the values of stroke...

Incidence and management of muscle imbalances in physically active and inactive populations: Objective rehabilitation solutions for populations with nonspecific back pain
Šmejkal, Jiří ; Zeman, Václav (advisor) ; Topolčan, Ondřej (referee) ; Kálal, Jan (referee)
v anglickém jazyce: Incidence and management of muscle imbalances in physically active and inactive populations: Objective rehabilitation solutions for populations with nonspecific back pain Summary Totally 258 patients with chronic low back pain aged 51,5 +8,4 years were treated for three weeks in the Rehabilitation Centre focused on lumbar back pain. We observed incidence of muscle dysbalances and accomplished their exact objectiveness using the Tergumed system. We tried to compare and solve their mutual influence during the rehabilitation treatment. We compared differences between physically active and physically inactive population, the impact of total motivation,age and other factors on the improvement of strenght, motion, dysbalances and total pain relief.Significant improvement of movement and muscle strenght p <0,001 were documented on the Tergumed in three weeks.The physically active population and patients motivated.by using the Tergumed preferred active exercises to passive therapy. We also observed improvement in finger-floor distance and reduction of pain, documented by the visual analogue scale, decrease in body weight and cholesterol level (p <0,001). In three- week observation nor significant changes in muscle dysbalance, neither their differences according to sex,age ,chronical...

Design of communication network in building for residential and commerce utilization
Šištík, Jan ; Zeman, Václav (referee) ; Novotný, Vít (advisor)
The bachelor's thesis deals with the design of a communication network infrastructure for a multi-storey building that combines residential and commercial use. The design is mainly based on the provided project documentation in the form of drawings and requirements of the investor. The thesis contains a description of the basic issues of networks, but also an analysis of the planned state and a description of the necessary resources for the implementation of the design.

Virtual Currencies
Mlýnková, Veronika ; Sikora, Marek (referee) ; Zeman, Václav (advisor)
This bachelor thesis deals with the topic of virtual currencies based on the blockchain technology. The foundations of the cryptocurrency workings are explained on cryptocurrency Bitcoin, which is later described in a greater detail from technological point of view. In addition to the general workings of a bitcoin network, this thesis describes creation of bitcoin addresses, the composition of transactions and the way they are sign and verified. A broader view of cryptocurrencies is offered within the fourth chapter, with the classification into generations and explanation of terms coin, token and stable coin. Chapter Ethereum explains the meaning of smart contracts and decentralized applications. Within the thesis a laboratory task was performed, which describes the procedure for programming a simplified version of blockchain in Python. To summarize the discussed topic, an educational web application was created.

Verification of PGP digital signatures
Horký, Matyáš ; Burda, Karel (referee) ; Zeman, Václav (advisor)
This bachelor thesis is focused on the interaction of OpenPGP content inside of e-mail files. It describes the history, changes and properties of PGP and e-mail and connects them into a common context. The goal is to design and implement a program for reading and verifying OpenPGP data in electronic mail, which is available as an open-source tool available as both a the command line and as a library.

Electronic signature in practice
Blahušová, Klára ; Sikora, Marek (referee) ; Zeman, Václav (advisor)
The topic of this work is electronic signatures and their use in the European Union, while consideration is also given to nations in the European Free Trade Association (Iceland, Liechtenstein, Norway and Switzerland) and others, such as Great Britain, USA and China. Description is given of legislation governing electronic signatures, the form this takes and differences between the aforementioned countries. Each section contains a list of relevant certificate authorities for the territories discussed therein. The first part defines what an electronic signature is and the theory behind it, whereas the other is devoted to application in said territories. A summary of the information provided herein is available online via a dedicated web app.

Web application for file encryption
Tatar, Martin ; Blažek, Petr (referee) ; Zeman, Václav (advisor)
The bachelor thesis is focused on developing a web application for file encryption. In the theoretical part symmetric encryption algorithms are divided into block ciphers and stream ciphers. Selected ciphers are described and their properties are compared. Then the modes of operation for block ciphers are described. The developed application encrypts both files and text inputs by the selected algorithm and can operate in various modes of operation. In addition to this functionality the application is supplemented with descriptions of available ciphers and modes of operation.
