Wireless Sensor Network with Static Topology for Building Monitoring
Koudelka, Jan ; Žák, Jakub (referee) ; Samek, Jan (advisor)
This bachelor's thesis is focused on realization of wireless sensor network (WSN) for buildings monitoring and real-time obtaining of data. Just for work on this project the micaZ sensor nodes have been chosen. The main task is to create WSN with a static topology and some communications mechanism. That network consists of several nodes, and there is a special one called base station. It also has a special function, different from the others. The function is that the base station is collecting data from all of the nodes and sending them to a computer through an USB port. In addition to designing the network topology the other tasks are to implement a comunication protocol and to create computer application and application for sensor nodes. Data will be visualised in text and graphical form. Moreover there are some information about the simulation tool called TOSSIM which allows testing applications without having a physical access to micaZ sensor nodes.

Wireless sensor network
Ševčík, Martin ; Fedra, Zbyněk (referee) ; Prokopec, Jan (advisor)
This bachelor thesis deal with the ZigBee wireless technology and design of a simple sensor network on its principle. The network is designed for a smaller apartment. As the temperature sensor is used DS1631 thermometer. Communi-cation of the coordinator with the computer ensures XPort®. Used modules from the Meshnetics company integrates the AVR processor and the radio transmitter / receiver at 2.4 GHz operating frequency.

Character Modeling - Polygonal Wrapper
Žák, Pavel ; Herout, Adam (referee) ; Chudý, Robert (advisor)
This project is engaged in optimalization of 3D polygonal models. Main automatic and also manual principles and methods used in the area of character model optimalization are introduced and discussed. Next the approach named geometry mapping, which was created as a part of the project and enables the creation of models with desired topology, is described.

Tetrahedral Mesh Processing Library
Hromádka, David ; Havel, Jiří (referee) ; Španěl, Michal (advisor)
Many architecure, medical and engineering applications need a spacial support for various numerical computations (i.e. FEM simulations). Tetrahedral meshes are one of perspective spatial representations for them. In this thesis, several possibilities of effective tetrahedral mesh representation for its generating and processing are described. A computer library for the mesh processing is proposed which can be characterized by memory efficient imposition of the mesh while preserving the ability to apply topological and geometric algorithms effectively. The library is implemented in C++ language using templates. Time and space complexity of typical mesh operations is compared with CGAL library and according to measurements the proposed library has lower memory requirements than CGAL.

Finding the network architecture for alarm transmission system LAN-RING
Mikšíček, Pavel ; Marada, Tomáš (referee) ; Zuth, Daniel (advisor)
This master’s thesis deals with a complex solution for the visualization of network topology. The first part of thesis describes the operation principle of LLDP protocol, which was chosen as a tool for retrieving informations from network traffic based on the requirement of the assignment. There is a detailed description of the LLDP protocol implementation in C language to METEL s.r.o. network products. The second part deals with possibilities of graphical interface in software SIMULand intended for managing network devices. It describes tools expansion process for the visualization of the network topology. In conclusion, the results of testing final solution are introduced.

Aplication of inteligent control elements in modern electrical instalaton
Dokoupil, Jan ; Mastný, Petr (referee) ; Bátora, Branislav (advisor)
This bachelor thesis deals with the field of intelligent wiring and presents its advantages in comparison with a classic electroinstalation. A special attention is devoted to the most widely used and expanded standard sof opened systems KNX/EIB. In the first part, an explanation of the way the inteligent wiring works, its main parts, topology and possibilities of control and visualization is provided. In the second part, the work is dedicated to presenting an energy savings, mainly in ligthening and heating, which are possible to achieve by using inteligent wiring, Finally, there is a project electroinstalation in a family house, which is built on the elements of the KNX/EIB system. There is also a comparison with the classic (conventional) wiring. Both projects are implemented by Astra software.

Uninterruble Power Supply (UPS)
Suchý, Petr ; Sekora, Jiří (referee) ; Chmelař, Milan (advisor)
My Bachelor's thesis deals with the question of Uninterruptible Power Supply (UPS). Continual power supply is required in many branches of the industry at the present time. It is very important to provide for question of UPS and it is necessary to evolve that. My qualified work refers to singular types of back-up power supplies, their possibilities and places of application. The work includes the proposal of block scheme for monitor located in the ward of intensive care, defined requires for each type of blocks and proposal of automatic packaging battery with 50Ah capacity.
