Computer Identification Based on Its Network Behaviour
Myška, Michal ; Halfar, Patrik (referee) ; Polčák, Libor (advisor)
This diploma thesis deals with computer identification using network behavioral patterns. Security functions providing privacy are described together with user privacy threats. Then, several approaches to the computer identification based on network behaviour are described. The proposed tool is based on data mining method Multinomial Naive Bayes. Then, the implementation of proposed tool is described and the experiments recognizing success in the identification are performed.

Automated Development of Network Attack Detectors
Huták, Lukáš ; Kováčik, Michal (referee) ; Žádník, Martin (advisor)
The thesis is focused on automated development of network attack detectors. It describes a design of patterns developed for normal and offensive behaviors based on monitoring network traffic of selected services. Patterns are represented by statistics with a focus on suitable metrics. Using machine learning algorithms attack detectors are created from behavioral patterns. Finally, a module was implemented for Nemea system in C/C++ programming language based on the proposal.

Endocrine disruptors in reptiles
Semerád, Jaroslav ; Kratochvíl, Lukáš (advisor) ; Cajthaml, Tomáš (referee)
The ability of environmental contaminants to influence reproduction and development in vertebrates via disruption of the endocrine system is widespread. The mechanisms through which xenobiotics act can be complex and vary greatly among species. Reptiles are particularly good models for studying endocrine affecting compounds due to the fact that different species differ in modes of sex determination (genotypic sex determination or temperature-dependent sex determination) and parity (oviparity or viviparity). The sex of individual is often determined by egg incubation temperature, and exogenous application of steroid hormones and their analogs or steroidogenic enzyme inhibitors can reproduce effects of temperature. The lability of sex determination in some reptile species offers opportunity to use gonadal sex as a marker for effects of endocrine disrupting compounds (EDC), even for the effects of extremely low dosages of EDCs or EDC mixtures. The neonatal offsprings exposed to EDCs during embryogenesis provide yet another way to assess endocrine disruption, i.e., measurement of steroid hormone levels in their blood. In addition, many reptile species are highly aquatic, they use habitats near agricultural areas, where usage of pesticides is the most intense, and they are carnivores or scavengers. Therefore,...

The influence of stress factors on the students of faculty of health and social studies
PILARČÍK, Jan
The main theme of this thesis is the influence of stress factors on the students at the Medical Social Science Faculty. Stress is a very broad theme and has a wide range of effects on the students. It can affect every part of our life. If we truly want to understand its influence on students Medical Social Science Faculty we first have to find its origin. In the theory part we find that a lot of authors agree that stress originates in us, it is in us, it comes from us and that we create it within ourselves. This diagnosis, however, is not satisfactory because there are great differences between the ways people create their own stress. We go on to find out what influences we tend to follow in creating behavioral patterns, as a nation, family or as individuals. These influences we regard as true and indiscriminately use as guidelines for our day to day lives. We find that from our early years we develop a view of the world around us using different mechanisms. One sees a glass half full and another half empty. So, also each one of us deals with problems and stressful situations in various different ways. We find different opinions on how to deal with the wrong influences and patterns in our lives. We realize that anyone, if they want and believe, can completely change beyond recognition and be happy. We also find that happiness is closely connected with the spiritual. The practical part of this thesis is done in the form of deep interviews with the students Medical Social Science Faculty. To my surprise the students were very open to these interviews. The thesis describes the stress factors on the students. I find that the field of stress factors is very wide and the students often have trouble dealing with it. Because they don?t know the principles, functions of stress and methods of how to work on themselves and how to get rid of it, they often seem to negatively influence its effects. Thanks to acquiring a deeper understanding of the subject, the obtained information can serve as a basis for improving the quality of education and the students? life. It can also be used for further research in the area of stress and its complications. I hope that my thesis will be an inspiration for others like myself who are trying to deal with stress and the problems and difficulties of student life and that it will encourage and help guide them in dealing with everyday life.

Devices for user behavior analysis on Twitter
Zoričák, Miroslav ; Jandoš, Jaroslav (advisor) ; Kafka, Daniel (referee)
People connected in a social network manifest certain patterns regarding their behavior, which are stemming from similar patterns emerging from conventional social networks. In my work I will try to describe some of these behaviors as they are projected on Twitter and how they apply when performing discovery preceding a marketing campaign as well as during post-campaign evaluation. From the practical standpoint I will try to apply this information on a real marketing campaign aimed at boosting sales as well as follower numbers.
