Static analysis of flexibly supported on structures
Šnajdárková, Jana ; Brdečko, Luděk (referee) ; Vlk, Zbyněk (advisor)
This work focuses on comparing the static analysis on the various types of models. It is calculated as manual calculations and in software RFEM. Without use of the software are created simplified beam model on fixed and flexible supports and to them are calculated support reactions, shear forces and bending moments. One part focuses on the calculation of the reduction of bending moments, to achieve more accurate results. In the program are created models of rod and models of space, which are composed of surfaces. There is also created a model of the split rod to form a reduction of the bending moments over the supports. The last model is a beam with two separate chambers, which are fixed to the plate and defined as ribs which cooperates with the plate. Internal forces on all models is then compared.

Malware Analysis: Tools and Techniques
Danilov, Marcel ; Luc, Ladislav (advisor) ; Veber, Jaromír (referee)
This bachelor thesis adresses present day topic of broad interest, the topic of malware. This term stands for malicous software as viruses, worms, trojans, spyware etc. Simply put a software with intent to do harm to the users of computers or mobile devices, to their steal information or gain access to their private computer systems. This thesis is divided into several chapters. First few of them are theoretical. First one describes malware in general. It defines what malware is and divides it into categories. Second chapter introduces a discipline of malware analysis. A discipline where malware, its components and behaviour is analysed in laboratory environment. This chapter contains general description of malware analysis, categories in which is this analysis divided, and rules of said analysis. Third chapter goes even further into malware analysis. It describes and identifies its indiviual techniques and tools. Last chapter is focused on practical usage of malware analysis. Theoretical knowledge of malware analysis, specifically knowledge of tools and techniques described in previous chapters is demonstrated on real, live example of malware. Thanks to demonstration of tools and techniques; funcionality, structure and life cycle of mentioned piece of malware is also being analyzed. Goal of this thesis is to bring reader closer to the topic of malware, with emphasis on area of malware analysis. This contains an explanation what an malware analysis is, what is its purpose. Next goal is to develop a summary of malware analysis basic tools and techniques. Thesis contribution is application of knowledge of techniques and tools on real malware analysis. With the help of malware analysis, this thesis demonstrates its individual tools and techniques on live example of malware. Other contributions are deriving from analysis itself. Funcionality, structure and life cycle of analysed piece of malware is also being explained.

Automatizace testování architektury studentských úloh
Hamendi, Mohammed ; Pecinovský, Rudolf (advisor) ; Pavlíčková, Jarmila (referee)
The freshmen programming courses at the University of Economics in Prague offer a unique approach to learning the art of programming and software engineering. The introductory courses follow the Architecture First methodology that gives students the opportunity to learn programming from the top down, without being constrained by the specifics and syntax of any one programming language. It teaches the thought processes needed to build programs, allowing the student to absorb the big ideas of computer programming. The average number of freshmen at the faculty of Informatics and Statistics is around seven hundred students. The task of correcting programming assignment and preparing appropriate feedback would be a mammoth undertaking for teaching staff in most university settings worldwide that offer similar computing degrees. It is therefore quite often the case that the faculty provisions some sort of automated testing technology that can handle the volume and provide both the teaching staff and the students with the tools needed to manage the assignments. These automated tools or systems have been, and continue to be, the subject of many research topics across the world and continue to evolve as new technologies and teaching methods evolve. This study first introduces the theoretical background of automated assessment and grading tools and systems and then provides an analysis of the fields current state. Taking that as input to the next phase, the study uses that information to then design and implement a custom-built system that would enable the automated testing of the structure and other aspects of student assignments. The main goal for the resulting system is to provide an intuitive and convenient way of declaring what needs to be tested for a given assignment and then providing the mechanism to run those tests automatically. The resulting system, DynoGrader, dynamically validates student assignments at runtime using Java runtime annotation processing mechanisms and Java Reflection API.

Possibilities of generation and usage of AST in PHP programming language
Kočárek, Michal ; Kosek, Jiří (advisor) ; Tichý, Jan (referee)
The thesis provides theoretical base for development of the DoXRef. DoXRef is a tool for generating the "x-ref" documentation from PHP source codes. As part of the thesis the tool has been developed and shows the conclusions from this work in practice. There is described the reason of choosing this topic and the arguments for the development of the DoXRef in the introduction. Theoretical part describes structures for analysis and modification of the source code. Thesis extends the abstract syntax tree structure by removing some of its drawbacks. In the chapters about parsing, the Pratt's algorithm is noted, which itself is simple to understand but still very effective. This algorithm is used in the project's parser as well. The practical part describes structure and features of the DoXRef tool and includes screenshots from the generated documentation as well. The source code and usage examples are provided as a part of this thesis. The contribution from this thesis is primarily the DoXRef tool. The tool can be extended into usable form and its parts can be reused in other applications. The source code is published under open-source license.
