Monitoring Service Properties of an IPFIX Collector
Kala, Jan ; Žádník, Martin (referee) ; Wrona, Jan (advisor)
This bachelor's thesis addresses possible ways of monitoring IPFIX collector, which is used for the collection of metadata about network traffic. The thesis briefly introduces the pro- blematics of monitoring and describes the current state of IPFIX collector, which is being developed by an organization called CESNET. It also describes service properties, which can be monitored during the process of data collection using the IPFIX protocol. A new plugin is described, which is intended for the collection and the export of service properties. The thesis describes an implementation and contains results of testing of the new plugin.

Secure Transport of NetFlow and IPFIX Records
Štěpánek, Adam ; Grégr, Matěj (referee) ; Podermański, Tomáš (advisor)
This bachelor thesis deals with an IP flow based data network monitoring system. It presents the architecture of the NetFlow based monitoring, explains the basic terms, the NetFlow protocol and its alternatives. Further, weak spots of the monitoring systems are determined and a conceptual solution is proposed. This solution is implemented and described in detail. Finally, testing methods and results are discussed and the possibilities of further development and optimization are proposed.

Heating of panel house with alternative preparation of TV
Bílek, Martin ; Adam, Pavel (referee) ; Horák, Petr (advisor)
The subject of this thesis is the heating and hot water preparation in the residential house in Brno. object has eight floors and basement. In each floor there are five residential units. In the basement there is a utility room with heating, gas boiler cascade. Used to heat-pipe heating system. Heating surfaces are plate and tubular body. The primary source of hot water is gas boiler. As a secondary source of alternative preparation with solar home stations. Each apartment has its own solar station.

Technical infrastructure in cities
Hladůvková, Blanka ; Hluštík, Petr (referee) ; Vrána, Jakub (advisor)
This bachelor's thesis consists of three parts: Theory, calculation and project. Theory deals with possibilities of laying utilities into the ground, collectors, technical corridors, technical cannals, basement manifolds and to the overhead lines. Furthermore, the issue of coordination between utilities and greenery both in the Czech Republic and abroad is also addresed. The calculation part includes water demand, rainwater quantity and waste water balance calculations. Project contains the accompanying report, technical report and drawings. It focuses on the Jircháře street located in Staré Brno, where a new apartment building has already been built, for which new relocation of utilities from Jircháře street to Kopečná street had to be made.

Solar heating tap water
Kracík, Petr ; Baláš, Marek (referee) ; Fiedler, Jan (advisor)
This bachelor thesis deals with the heating of hot service water by means of solar energy through solar collectors. At the beginning the author describes the most frequent methods for heating of service water in Czech houses with the help of electrical energy, fossil fuel, gas and central heat supply, including the input expenses for buying equipment. The author describes a solar system and his basic elements and suggests two variants with supplement heating by means of electrical energy, which compares with electrical heating of service water. The overall thesis is conceived as a review of possibilities of heating hot service water in households with economical budget at the end of the work.

Basic measurement of bipolar and unipolar transistor
Kaňa, Leoš ; Šebesta, Jiří (referee) ; Dřínovský, Jiří (advisor)
In terms of the better effectiveness in the sphere of transistor characteristics measuring, no matter unipolar (FET) or bipolar (BJT), in laboratory conditions and their better understanding in terms of thrash out a subject matter is desirable have to available workplace let us say preparation enabling this kind of measuring with modifiability wiring and with possibility to change measured component. This thesis isn‘t focused only on development of this kind of universal component for measuring but simultaneously contains brief summary about the theory and parameters of transistors. Next aim is the development and realisation of static characteristic measuring program in VEE 8.0 Pro environment. Finally the complex laboratory exercise has to be done for measuring of bipolar and unipolar transistor’s static characteristics include programs for automatic measuring. For developing of DPS was used developing system named Eagle which gives us instrument with sufficiently accuracy. In thesis is contained theory needed for measuring and programming. Except possibility of measured component change we can change transistor connection in circuit on the board. This change is available for BJT (CE, CB, CC) and unipolar JFET (CS, CG, CD) transistor’s.

IP Flow Filtration and Profiling
Sedlák, Michal ; Tisovčík, Peter (referee) ; Kučera, Jan (advisor)
This thesis addresses the problem of filtering and profiling IP flows, primarily data of IPFIXsystems. Within the work, a general filtering component is designed and implemented, whichaims to be sufficiently efficient and flexible for use in other projects related to IP flows. Thiscomponent is then adapted to work with data in the IPFIX protocol format and integratedinto the existing modular collector IPFIXcol2 in the form of plugins adding the support forfiltering of passing IPFIX data and their sorting into profiles.

Design of system control and diagnostics water heating using solar energy
Kužel, Kristián ; Zuth, Daniel (referee) ; Vdoleček, František (advisor)
This thesis deals with problems related to heating of hot service water. It focuses on solar water heating, describes individual types of solar panels and summarizes the existing information about solar water heating. It demonstrates actual problems of solar system solution on a specific example of a two-generation family house, where it analyses possibilities of diagnostics and control of such system. It also deals with suggestions of possible expansion of the current solar system.

Extraction of Available Information from SSH Protocol Headers
Ďurčanský, Norbert ; Bartoš, Václav (referee) ; Kořenek, Jan (advisor)
This paper analyzes issue regarding to extraction of available information from SSH protocol. To achieve this aim, knowledge about SSH protocol were used to implement plugin for FlowMon exporter. During the testing plugin was tested on real network and validated in terms of stability, efficiency and accuracy. The result plugin allows us to extract information from SSH protocol and futher analysis without decryption of traffic.
