Enhancement of Probabilistic Methods for Password Cracking
Lištiak, Filip ; Polčák, Libor (referee) ; Hranický, Radek (advisor)
This thesis describes passwords cracking using probabilistic context-free grammars, specifically PCFG Cracker tool. The aim of the thesis is to design and implement enhancements to this tool, which reduce the size of output dictionaries while maintaining acceptable success rate. This work also solves critical parts in the tool that slow down the overall duration of the program. Another goal of the thesis is to analyze and implement targeted attack dictionaries that increase the scope and success rate of generated passwords.

Distributed Password Generation Using Probabilistic Grammars
Mikuš, Dávid ; Ryšavý, Ondřej (referee) ; Hranický, Radek (advisor)
This thesis describes a process of cracking a password, existing types of attacks and generating passwords using probabilistic grammar. This grammar can be used as an attack that works on the basis of learning from an existing list of passwords and generating them by using constructed context-free grammar from the learning phase. The core of this thesis is the design and implementation of distribution solution for this type of attack. Implementation includes refactoring of existing solution and optimization to maximize use of every available resource.

Lexicographical analysis of words from the thematic field "car industry" in the printed and internet dictionaries.
TŮMOVÁ, Klára
The aim of this bachelor thesis is to evaluate whether dictionaries can cope with the rapid entry of technical headwords into the language. The theoretical part deals with dictionaries, their types, headwords and structure. The aim of the practical part is to compare , with the aid of twenty selected headwords from the fiels of automotive industry, how the three dictionaries we chose, approach the newly arrived technical terminology. The task was also to find out, whether the printed dictionaries are still appropriate aids for translators and interpreters, or wheter the quick-witted and unlimited electronic dictionaries have already surpassed them.

Google Econometrics: An Application to the Czech Republic
Platil, Lukáš ; Horváth, Roman (advisor) ; Červinka, Michal (referee)
This thesis examines the applicability of Google Econometrics - the use of search volume data of particular queries as explanatory variables in time se- ries modeling - in the case of the Czech Republic. We analyze the contribu- tion of Google data by comparing out-of-sample nowcasting performance and in-sample fit with control variables in three related areas: using an auto- regressive model for unemployment, vector autoregression and logit models for GDP and household consumption, and Granger causality test for consum- er confidence. The improvement in quality of unemployment nowcasting is modest but statistically significant; sentiment index based on Google queries shows reciprocal relationship with the official Consumer Confidence Indicator, and it also provides superior nowcasts for household consumption as well as in- sample fit in logit models; its performance in GDP nowcasting is average among control variables. In overall, the results suggest that Google Econometrics is applicable also to the Czech Republic, despite the fact that the internet penetration rate and Google popularity was lower over the analyzed period compared with developed economies where these methods were usually tested. In the future, Google data may be used together with other leading and coincident indica- tors to...

The safety of seniors in the Internet cyberspace
Burešová, Martina ; Ondrušová, Jiřina (advisor) ; Cimrmannová, Tereza (referee)
DIPLOMOVÁ PRÁCE The safety of seniors in the Internet cyberspace Ing. Martina Burešová Praha 2015 This thesis focuses on issues of use of Internet environment by seniors. I deal with benefits and risks of the cyberspace. I describe how the Internet environmet can affect the quality of life. Specific risks and actions to prevent them are defined theoretically. The theoretical description is afterwards enhanced by actual experience from my long-term work of teaching courses on computers to seniors and handicapped people. I present examples of good practice. In the practical part, I concentrate on research of safe manners of seniors in the Internet cyberspace. I organized the research as secondary activity of the education itself. I used questionnaires, tests, interviews and observation for the research. The goal of the research was the evaluation of seniors' compenences of safety manners in the cyberspace. I assume from the results of the research that seniors' competences are insufficient. I believe, subject to my observation and in compliance with safe off-line communication analysis and following evaluation of hypotheses, that safe manners may be taught to seniors using appropriate method of education.

The Entry "Fashion" in Czech Encyklopedias
Schambergerová, Lucie ; Hlobil, Tomáš (advisor) ; Jarošová, Helena (referee)
The thesis "Entry "Fashion" in Czech Encyclopedias" analyses an evolution of aesthetic viewpoint of the entry "fashion" since its first appearance (the first Encyclopedia in Czech language from 1866) until recently (the Entry Fashion in 2001). The thesis research method is based on Jan Mukařovský's theory of function, value and norm of the aesthetics and his commentaries on fashion, which I made a subset to my own term aesthetic viewpoint. For better orientation I first decided to summarize particular analyses of each entry into a spreadsheet which makes development, way of characterisation and terminological variability of aesthetic viewpoint apparent in a more complete way. The main goal is to answer the following reasearch questions: 1. Do authors distinguish between fashion as a norm and fashion as a form of clothing? 2. Which terms are being used to thematize the aesthetic viewpoint? 3. What is the context of the aesthetic viewpoint of fashion?
