Smart Home Security System
Dragúň, Peter ; Bidlo, Michal (referee) ; Vašíček, Zdeněk (advisor)
This thesis deals with the security of flats and houses using Bluetooth Low Energy (BLE) technology. The aim of the thesis is to develop an electronic security system for access and intrusion control exploiting the possibilities of Bluetooth Low Energy technology for improved user experience. The thesis describes security systems, BLE technology and ESP32 microcontroller. The creation of a mobile application that is used to set up the system and its management is included, as well. The thesis also describes the design, construction of a prototype and its implementation. The last part is the verification of functionality, testing and suggestions of possibilities for further improvement of the created prototype.

Design of enterprise IEEE 802.11 wireless networks
Hlavatý, Josef ; Kubánková, Anna (referee) ; Novotný, Vít (advisor)
This bachelor thesis focus on wireless networks standardized as IEEE 802.11 and their use in wide wireless networks. Wireless transmissions and most known accessories of standard IEEE 802.11 and their functions are theoretically discussed in the first part of the bachelor thesis. Next, bachelor thesis takes care of architecture of vast wireless networks, their division into cells and centralized management of cells and individual AP. Further, security and authentication in wide wirreless networks is described. The second part of bachelor work is formed from detailed manual for execution of wide wireless networks, from which laboratory task is built for subject Network Architecture.

Accelerator Driven Nuclear Power Plants
Jarchovský, Petr ; Krása,, Antonín (referee) ; Katovský, Karel (advisor)
This bachelor’s thesis deals with utilization of spent nuclear fuel in nuclear power plants of new generation – accelerator driven nuclear power plants and of conversion of this fuel into electrical energy. In the introduction are listed basic physical and theoretical knowledge of nuclear reactors along with their basic division and global distribution. As another point accelerator driven systems are described with their brief development and the basic concept and usage on both the nuclear power plants and transmutation technologies. Some global projects are mentioned here dealing with this system and conduct research. More into detail is point about European projects MYRRHA and ESS, because there are important research facilities worldwide. The next are projects with liquid target as a very promising medium. The last part deals with the calculation of basic parameters of ADS in the MCNPX and its applying.

System for Guarding and Securing Objects and Areas
Kuchařík, David ; Kubek, Ján (referee) ; Strnadel, Josef (advisor)
This project deals with given safeguard possibilities, both mechanical and electronic. A row house with garden was chosen for being secured. Subsequently, were elaborated two`s proposals of securing and guarding of this object. First, was based on camera`s system and second on common system ESS. Later on they were evaluated and the most considerable benefits were emphasized. A system based on control panel with connected detectors was selected upon specification. Subsequently was created a model of the chosen system, at which the required behaviour was simulated and verified. An outline of an implementation was created in the C language.

Security system with mobile phone communication
Ulbrich, Jakub ; Holek, Radovan (referee) ; Macho, Tomáš (advisor)
This thesis deals with the question of electronic security systems. In the forepart are described electronic security system components such as keyboards, detectors, alarm devices etc. Various methods of security or de-security of properties, trespassing and other events detection methods, and ways of alarm calling are described there too. The next part of the master’s thesis focuses on the construction of an alarm system which is designed for security of a common-size flat with one entry. The system manages to control up to four movement detectors. The operation of the system is handled by a 16 button keyboard, and easy orientation is provided thanks to a liquid crystal display. The alarm is signaled by an indoor alert siren, however, other alarm announcing devices with an input matched for the log. 0 or log. 1 reception can be connected too. The system contains communication equipment (mobile phone) which signals alarm at a distance to the three telephone numbers. User can use a distance control by text message to unlock system or to determine its status. The system is controlled by the microcontroller AVR ATmega16, the product of Atmel company. A brief description of all components of the electronic alarm system is included in this work.

Alternative family forms in the Czechia in the 21st century
Bošková, Mariana ; Kurtinová, Olga (advisor) ; Bartoňová, Dagmar (referee)
Alternative family forms in Czechia in the 21st century Abstract The aim of the thesis is to evaluate the development of alternative family forms in Czechia in the 21st century. These forms seem to be increasingly popular and more represented within households. The largest part of the research is devoted to unmarried cohabiting households. The characteristics of persons in these forms of cohabitation are presented in terms of their age, highest level of education, religion, and these households are also analysed according to the presence of children and their financial situation. The data are taken from the EU-SILC and ESS surveys from years 2010, 2012, 2014, 2016 and 2018 and the year 2011 is also added with data from the Czech population and household census. The grow index is included to assess the evolution between years and a logistic regression for the analysis of opinions on unmarried cohabitation as well. Households of unmarried cohabiting partners and singles persons are becoming increasingly popular. The increase is particularly evident in the younger age groups. Key words: cohabitations, same sex unions, de facto partnerships, singles, EU-SILC, ESS, households, Czechia

Utilization of technical and informaticalservices for protection of property and individuals at schools
Reindl, Filip ; Lustig, František (advisor) ; Stejskal, Martin (referee)
TITLE: Utilization of technical and informatical services for protection of property and individuals at schools SUMMARY: The objective of this work is to deal with problematic of security systems and their possible use at school buildings. It summarizes the current legislative on the field of security systems and in particular the protection of personal data and explains the principles of function of security systems. The main emphasis is on electronic fire alarm system (FS), electronic security systems (ESS), electronic access control (ACS) and closed-circuit television (CCTV) components in terms of hardware, communications and data utilization. The work also includes a model of practical comprehensive security system design for actual school building. KEYWORDS: Functions, systems, FS, ESS, ACS, CCTV 4
