Automatic Template Pattern Recognition
Kovařík, David ; Lengál, Ondřej (referee) ; Šimková, Hana (advisor)
Spam se typicky nevyskytuje ve formě samostatných zpráv, ale často bývá sdružován do takzvaných kampaní. Ty bývají automaticky generovány pomocí šablon. Díky tomu jsou jednotlivé zprávy sémanticky, ale ne syntakticky, ekvivalentní. Cílem práce je navrhnout algoritmus schopný z množiny zpráv jedné kampaně zpětně extrahovat šablonu, ze které tyto zprávy byly generovány. Práce se zaměřuje na spam v SMS komunikaci, ale navržené postupy jsou dostatečně obecné pro širší použití. Algoritmus je postaven na metodě zarovnávání dvou sekvencí, používané v bioinformatice pro nalezení podobných oblastí proteinových řetězců. Výstupem je regulární výraz popisující šablonu dané kampaně. Součástí řešení je také nástroj pro vizualizaci šablony pomocí HTML.Řešení bylo ověřeno na přibližně třech stovkách skutečných kampaní z celého světa. V naprosté většině případů je poskytnutý výsledek postačující pro identifikaci kampaně.

Social Transformation of the Czech Borderlands, as illustrated by districts Šumperk and Zábřeh 1945-1960
Mrňka, Jaromír ; Spurný, Matěj (advisor) ; Kovařík, David (referee)
MRŇKA, Jaromír: Proměny společnosti v pohraničí českých zemí na příkladu okresů Šumperku a Zábřeh 1945-1960. (Social Transformation of the Czech Borderlands as Illustrated by Districts Šumperk and Zábřeh 1945-1960). Master Thesis. Prague: Charles University in Prague, Faculty of Philosophy and Arts, Institute of Economic and Social History, 2013, 195 p. Based on research into regional context, the thesis "Social Transformation of the Czech Borderlands as Illustrated by Districts Šumperk and Zábřeh 1945-1960" contributes to a deeper understanding of the process of constituting a new society in the Czech borderlands. The research field is defined on the one hand by the structural aspects of demographic changes following the Second World War (the forced expulsion of the German population, the impact and consequences of unorganized and organized colonization process), on the other by the constitution and transformation of the communist rule, including the deep crisis from 1953 to 1957. In observing the changes of dominant and authoritative discourses on the one hand and the language of the acteurs on the other, the thesis identifies core values and images which contributed to the stabilization or destabilization of communist rule. The shared vision, enabling the mobilization of the society, was the...

Information System Selection
Kovařík, David ; Pezlar,, Zdeněk (referee) ; Koch, Miloš (advisor)
The thesis focuses on the selection process and the implementation of the new information system (hereinafter "IS") in a manufacturing company. This is achieved by detailing characteristics of all individual phases and steps of the selection and implementation processes in the context of one appointed company. The characteristics analysis identifies key factors which need to be managed well by the company in order to accomplish a desired outcome. The thesis also includes a generic and coherent framework and it concludes with a comprehensive proposal which can be used as a tool for a successful selection and implementation of the new IS.

Draft of Optimization of Web Application for B2B
Kovařík, David ; Weirich, Pavel (referee) ; Řešetková, Dagmar (advisor)
The purpose of this thesis is to design optimization of a webpage application designated for the B2B sector, which should improve a user experience in a significant way. A user experience issue was solved by analytical activities oriented on the webpage of www.webstopar.cz. The results of the analysis were supplemented by a qualitative research. The result of the bachelor thesis is a design of optimization of particular aspects of a user experience. The design implementation should improve the webpage quality from the point of view of a user experience and also bring the benefit of 10% increase in users of the service offered on the webpage. Moreover, the final design of this work is generally applicable for a large variety of Czech and foreign webpages.

An Interactive Simulator for Data-flow Graphs
Kovařík, David ; Smrčka, Aleš (referee) ; Charvát, Lukáš (advisor)
Data-flow graphs are often used by hardware designers. Such graph representation is also very useful for performing deeper analysis of a design (including functional or formal verification). Simulator presented in this thesis is a support tool for verification environment HADES. The goal of the simulator is to decrease necessary time and increase quality of the verification process. To perform a simulation efficiently, a specific simulation algorithm which saves computation time by eliminating redundant evaluations has been introduced. The simulator is equiped with several output interfaces connected to a single simulation core. One output interface provides direct simulation output in text format. The second is also textual, but allows user to control the simulation. Finally, the third forms a graphical interface that visualizes simulation results.

Dodacie parity a ich vplyv na stanovenie ceny - implikácia na Carrefour ČR
Kováčová, Veronika ; Malý, Josef (advisor) ; Kovařík, David (referee)
Diplomová práca je zameraná na najnovšie vydanie dodacích parít Incoterms 2000 a ich základnú charakteristiku, tj. popisuje práva a povinnosti predávajúceho a kupujúceho. V prvej časti práca popisuje význam logistiky a dodacích parít v medzinárodnom obchode a obsahuje taktiež výklad dodacích parít. Nasledujúca časť je zameraná na krátke predstavenie spoločnosti Carrefour a jej importného oddelenia a analýzu vplyvu dodacích parít na stanovenie ceny v medzinárodnom obchode. Táto analýza vplyvu je predstavená na konkrétnom príklade, spoločnosti Carrefour ČR.
