Computer-assisted Search of the Roots of the Polynomial
Smetana, Bedřich
This article describes finding roots of polynomials, specifically aimed at finding real roots of a polynomial. Computer Support focuses on the use of generally available programs such as spreadsheets, portals to solve mathematical problems and freeware applications. Attention is devoted to a comparison of commercial and open source software.

Web security
Omelka, Antonín ; Havránek, Martin (advisor) ; Benda, Petr (referee)
This thesis is focused on web pages security problematic, specifically web application problematic. These applications usage is wider then classical static web pages. Problem of web application is a security. They are normally reachable form anybody on internet and it is strong motivation for attackers. Main topic of this thesis is web e-commerce application Magento and security analysis of specific vulnerability which allows full control for attacker. Other goals are risk and vulnerability analysis connected with web pages development such as SQL Injection or Cross-Site Scripting. Also comparison of vulnerable Magento version and its secured version. Last goal is recommendations about own attacked e-shop.

Simulation of electric drives in freeware program
Hnilica, Peter ; Cipín, Radoslav (referee) ; Huzlík, Rostislav (advisor)
The purpose of this thesis is to find and then to test the freeware alternative to Simulink. Introductory section presents short overview of the bachelor´s thesis. The second chapter is devoted to a search of available programs and to explore their potential for another use in the simulation process. In the third chapter are theoretical knowledges required for further work in simulation programs. The fourth chapter describes the simulation process of selected electrical machine in Simulink and in his freeware alternative as well as export measured values to an external file and comparison of these values. In conclusion are evaluated simulation results, including the ability of freeware alternatives to replace fully Simulink.

Usage of freeware project management tools in the Czech Republic
Blažík, Radek ; Šťastný, Petr (advisor) ; Chlapek, Dušan (referee)
The purpose of this thesis is to discover in what scale freeware project management tools are used in the Czech Republic. The specific goal of this thesis is to verify whether these two hypotheses are true: Freeware project management tools are not used by majority of organizations in the Czech Republic. Freeware project management tools do not reach the functionality level of commercial software. This objective is achieved firstly by making a survey in the whole state scale in the field of information and communication technology and secondly by evaluating the most widely used freeware project management tools, based on the survey, by their functionality level and by considering their ability to replace commercial software. The contribution of this thesis is to discover the actual state of project management tools usage in the Czech Republic, to introduce these facts to the companies at this market and to define the functionality level of presently used freeware project management tools. The structure of this thesis is based on three parts. The first part refers to general information about project management such as its terms, usage, processes, factors that affect goals of a project, methodologies and tools. The second part involves the analysis of project management tools usage in the Czech Republic. The third part provides the most widely used freeware project management tools evaluation analysis.
