Kovács, Benjamín ; Holík, Milan (referee) ; Ondrák, Viktor (advisor)
The subject of the „The project proposal for building an ISP network“ thesis is the analysis of a current state of internet connectivity in a city of Komarno as well as a project proposal of a new network infrastructure for an internet service provider. The analysis consists of the current state of infrastructure and a possibilities of building new ISP network infrastructure. This thesis also contains brief summary of a required technologies and a description of project management, including project risk analysis, time schedule and cost calculation.

Variable Two-Way Loudspeaker Cabinet - Laboratory Tool
Rehák, Jan ; Schimmel, Jiří (referee) ; Balík, Miroslav (advisor)
The objective of this work is to build a two-way loudspeaker system that will enable changing loudspeaker topology in both vertical and horizontal axes and to suggest two laboratory tasks. The theoretical part of this work will briefly discuss loudspeaker crossovers. Then it will discuss how topology of loudspeakers in a loudspeaker system can affect its behavior at crossover frequency. Frequency characteristics of various loudspeaker baffles will be shown. On these, the effect of a baffle’s exterior on its behavior will be discussed. A two-way loudspeaker system will be designed. The construction process and drawings of each part are also included in this work. The finished product will be tested and, following from these tests, a conclusion will be drawn about the validity of the theoretical assumptions of its design. After that, appropriate parameters of a crossover for the two-way loudspeaker system will be chosen.

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.

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.

Object Description in Images
Dvořák, Pavel ; Šmirg, Ondřej (referee) ; Zukal, Martin (advisor)
This thesis consider description of segments identified in image. At first there are described main methods of segmentation because it is a process contiguous before describing of objects. Next chapter is devoted to methods which focus on description identified regions. There are studied algorithms used for characterizing of different features. There are parts devoted to color, location, size, orientation, shape and topology. The end of this chapter is devoted to moments. Next chapters are focused on designing fit algorithms for segments description and XML files creating according to MPEG-7 standards and their implementation into RapidMiner. In the last chapter there are described results of the implementation.

Computational analysis of column for horizontal boring centre
Fargač, Michal ; Vosynek, Petr (referee) ; Hadaš, Zdeněk (advisor)
The theoretical study of this thesis deals with different approaches that can be used to optimize the topology of various structures. Main attributes and principles which they are based on of individual methods are discussed. The first point of the practical part is to design the model for computational analysis of stand and other machining centre parts based on real machine TOS FU. Afterwards, the model is analyzed to determine the dynamic characteristic of the machine. Subsequently, several changes of the stand design are performed in order to improve the dynamic behavior. Eventually, new stand kernel is designed which aims to enhance these dynamic characteristic. This model is analyzed again and the results are compared with the original form of the machining centre.

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.
