Using measuring probes ( for tools and workpieces) for production machine of range of products firm TOS KUŘIM
Kohút, Josef ; Holub, Michal (referee) ; Opl, Miroslav (advisor)
The purpose of this dissertation is to familiarize the reader with basic recognition of machine measuring probes for tools and workpieces. Namely then in area of measurement on CNC machining centers. Both recognition from aspects of principle of function of sensing elements and type of transmition to control system, and recognition from constructional aspects are described here. Further it puts mind on equipment of machine probes (touches etc.) and rules for best selection of this equipment. Next part of this work describes selection of appropriate probes, for universal machines from production of firm TOS Kuřim. Last part deals with testing of designed measuring system for concrete machine from production of firm TOS Kuřim. His typical composition, evaluation of tests results and achieved accuracy is also described here.

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.

Differential electromagnetic analysis
Novotný, Bohumil ; Člupek, Vlastimil (referee) ; Martinásek, Zdeněk (advisor)
This diploma thesis studies the theory side channels, simple and differential analysis, and types of attacks on the side channel, which may be run against the cryptographic system. The thesis explains the principles of side channel attack on a possible defense against them. The second part of the thesis describes experimental work created, its individual components and their functions. The findings builds custom solutions attack the electromagnetic side channel using electromagnetic probes and the workplace equipment developed for this task. The final part of the thesis is devoted to the description of the implemented algorithm, a description of measurement, measurement results and possible modifications of algorithms implemented in the microcontroller for full automation of the attack on the device, against which the attack was conducted.

Evaluations of the durability EIS probes installed in an earth dams
Koudelková, Eva ; Novotná, Jitka (referee) ; Pařílková, Jana (advisor)
This thesis deals with the assesment of the durability of electrical impedance spectrometry method (EIS) probes installed in earth dam. The chosen earth dam is called Bezedník III and the main reason for choosing this particular dam was the longest period of monitoring this dam. The measuring was carried out by the Z-meter II device during the years 2006–2012 and Z-meter IV device in the year 2016. The recorded data are processed and assessed in this bachelor’s thesis.

Monitoring of the temperature stratification of water using EIS method
Műnsterová, Zuzana ; Novotná, Jitka (referee) ; Pařílková, Jana (advisor)
Bachelor thesis examines the possibility of using the measuring apparatus based on the application of the method of electrical impedance spectrometry (EIS) for monitoring the temperature stratification of the water. For measurement are used the devices Z-meter III and Z-meter IV, which were designed in project E!4981 and E!7614 international applied research in program EUREKA. Part of the thesis is also a proposal of the probe. The experiment is carried out in a laboratory conditions, Laboratory of Water Management Research, Faculty of Civil Engineering, Brno University of Technology.

Preparation and application of physical hyaluronan gel
Kovářová, Lenka ; Krouská, Jitka (referee) ; Venerová, Tereza (advisor)
Bachelor's work is concerning by research in physical hyaluronan gel area. Research is focusing on its preparation, especially by interaction of hyaluronan (HyA) solution with opposite charged surfactant in physiological solution (0,15 M NaCl). In the first part of work I found out influence of molecular weight, concentration of original hyaluronan solution and the ratio of binding sites on hyaluronan chain and surfactant on amount of solids in gel, expressed in percent. Finally we can say, that this value is not influenced by molecular weight of HyA neither relation of binding sides. On the other side, concentration of original HyA solution has significant influence on amount of solids in gel. There was also researched process of gel swelling, where was set amount of water (in percent) able to take dried gel back. Analogical conclusion has been reached like amount of solids in gel. In other part were researched influence of hyaluronan molecular weight and the ratio of binding sites on hyaluronan chain and surfactant on formation of excimers and spectrum change by fluorescence spectroscopy. Pyrene, 1,3-bis(pyren-1-yl)propane (P3P) and prodan were used as fluorescence probes. Excimer emission showed at P3P, while there was no growth of intensity at 470 nm for pyrene. It was found that molecular weight does not affect the value of the ratio of excimer and monomer probe P3P, or the ratio of the first and third peaks of pyrene. The ratio of binding sites HyA and surfactant influence only relation of excimer to monomer (P3P probe), while influence to relation 1:3 hasn't been noticed for pyrene. I have compared spectrum of developed gel for prodan probe, relevant solid and swelled gel by return. It also served for drying and swelling process visualisation.

Traffic Analysis of Network Protocols Kerberos, NTLM, and SAML 2.0
Krůl, Michal ; Orsák, Michal (referee) ; Tisovčík, Peter (advisor)
This thesis engages the problem consisting of analysis and detection of the attacks carried out on the authentication protocols in the environment of network structures, like those used in big corporations. In~this thesis, the problem is examined in the light of the netflow analysis. Main content of the thesis is a simulation of the attacks targeting network architectures, where the authentication is served by mentioned protocols, and effort to detect these attack by the netflow monitoring. The outcome of this thesis is a draft, how to automatically detect the attacks carried out in the network structures, and plugin for the exporter of the Flowmon sond, the product of Flowmon Networks company, which will be extracting the information needed for the performance of the detection.
