Self Test of FlowMon Probe
Kříž, Blažej ; Kaštil, Jan (referee) ; Kořenek, Jan (advisor)
This thesis deals with development of built-in self-test for FlowMon probe, device for monitoring network traffic based on IP flows. At the begining, both NetFlow technology and the FlowMon probe are described and related terms are summarized. The development itself consists of requirements specification and analysis, design of general testing technique, desing of particular tests, their implementation and solution review.

Current distribution on linear antennas
Dvořák, Zdeněk ; Puskely, Jan (referee) ; Nováček, Zdeněk (advisor)
Bachelor’s thesis of Current distribution on linear antennas is concerned about possibilities of measuring current distribution on antenna. There is also close peak on measuring principles with help of measuring loop. Current in the loop is inducted in continual proportion to magnetic induction, which is inducted by the current distributed on antenna conductor in proximity of measuring loop. There are also described important parameters of antenna, which can be got from current distribution. This thesis discusses about the method of measure with the sonde in more detail. The expanded program DISTRIB helps to process measured values. This program is modified specially for short and long antennas. There is enclosed the projected submission of laboratory exercise, an exemplary protocol and sinusoidal regression calculation, which is used by the computer program.

Software Architecture for Flow Based Monitoring Probe
Špringl, Petr ; Kořenek, Jan (referee) ; Martínek, Tomáš (advisor)
This thesis deals with design and implementation of software architecture for Flexible FlowMon probe, accessories for monitoring high speed computer networks based on IP flows. The probe has been developed in project named Liberouter. There is described flow based monitoring and export formats NetFlow version 5, NetFlow version 9 and IPIFX, which are very widely used. The thesis contains description of hardware part of Flexible FlowMon probe including its requirements for software, which are the base of the whole software architecture. There is detailed description of that part of software architecture which was implemented during the work on this thesis.

Platform for Measurement of Atmospheric Quantities
Hanák, Jiří ; Vlk, Jan (referee) ; Chudý, Peter (advisor)
This work is dealing with the design and implementation of an embedded system for aerology measuring. The aim of the system is to monitor atmospheric states during an ascent in the suspension under an meteorological balloon. First of all, attention is given to the Earth's atmosphere and its quantities, then an overview of existing systems for performing aerological measurements. The core of the work is focused on the choice of measurement techniques and the selection of suitable measuring elements for a given scenario. The aerological probe is using atmospheric sensors HIH-8131-021-001, MS5611-01BA03 and PT1000-550 for temperature sensing, while GNSS data is received using the MAX-M8Q-0 module and the measured data is stored on a microSD card and transmitted in parallel using the MTX2-434.650-10 radio module. The system is controlled by STM32L1 from STMicroelectronics programmed in C using HAL abstraction layer.

Passive capturing probe for IEEE 802.11 standard
Partnov, Denys ; Pospíšil, Ondřej (referee) ; Pospíšil, Jan (advisor)
The bachelor’s thesis deals with a general description of the 802.11 protocol, where the individual layers on which the protocol works are explained and described. Attention was also focused on the possibilities of securing wireless traffic. The practical part then deals with the creation of a complete tool for passive interception of traffic in IEEE 802.11 networks. Where it is mainly about processing traffic statistics. The resulting program, written in Python, allows the user to display current information such as: number of transmitted frames, channel, band, received signal strength, and more. Subsequently, the results can be displayed in the form of graphs. As part of the test measurement, the correct functionality of the program was verified.

Universal Inspection and Measuring Station
Brýdl, Adam ; Bradáč, František (referee) ; Knoflíček, Radek (advisor)
The task of this thesis is the design and construction of semi-automatic control and measuring station. The station is designed for testing the presence and measurement of the correct position of light guides and seals in the connector. Station contains a tool for testing the blinding of connectors. The design and construction of a semi-automatic control and measuring station is necessary using several types of sensors and sliding linear axes controlled by servo drives. The assignment of the thesis is solved in cooperation with the company Mechatronic Design & Solutions s.r.o. in Brno.
