Thermal analysis of plastic part using finite element method
Zemanová, Lucie ; Nečas, David (referee) ; Zatočilová, Aneta (advisor)
The bachelor thesis deals with the thermal deformation of a plastic component after thermal loading and ways of processing digital data for a thermal analysis. There is optical digitizing outlined, since input data were obtained this way, and methods of subsequent processing for the thermal analysis. The analysis is carried out by the finite element method using ANSYS Workbench software. The finite element method is described. The work builds on measuring performed by photogrammetry, the aim is to compare applicability finite element method and photogrammetry for measuring deformation.

Decompilation of Selected C++ Constructions
Mihulka, Tomáš ; Zemek, Petr (referee) ; Matula, Peter (advisor)
This bachelor's thesis deals with the reconstruction of a hierarchy of classes and their virtual methods from programmes created by C++ language . The aim of this work is to extend a decompiler , which has been developed as a part of the Lissom project, by an analysis of those reconstructions for various decompilers . The reconstructions are created through detection of RTTI and virtual tables . The first part of this thesis involves a description of reverse engineering as well as of the Lissom project in terms of the decompiler . The following section of the paper explains the basics of C++ language , its structures and different possibilities of their decompilation . The final part of the paper deals with a design, implementation and testing of a recognition of RTTI and virtual tables .

Functions Detection in Decompilation
Kábele, Břetislav ; Ďurfina, Lukáš (referee) ; Křoustek, Jakub (advisor)
This work describes methods of functions detection in decompilation. It contains basic information about reverse engineering and its applications in computer science and beyond. Decompiler developed by research group Lissom at FIT VUT Brno is introduced. The main objective is to elucidate several methods of functions detection, discuss their advantages and disadvantages, and identify the problems of functions detection. After detecting the start, end and body of function, it is needed to find the parameters and return values. There are some algorithms presented in this area. The output of this thesis is design and implementation of architecture independent function detection and parameter detection.

Reconstruction of Data Types for Decompilation
Matula, Peter ; Ďurfina, Lukáš (referee) ; Křoustek, Jakub (advisor)
This document describes methods for a reconstruction of data types in the decompilation problem. It defines the concept of reverse engineering and introduces decompiler developed by the Lissom project. It presents existing methods of reconstruction of the simple and complex data types, and explains in detail approaches based on data-flow analysis and analysis of the memory operation offsets. The core of this thesis is the design of a new technique of reconstructing simple and complex data types, suitable for deployment in a retargetable decompiler environment of the Lissom project. Basic principles of the new technique, its implementation and related changes in decompiler and intermediate language are described. The solution is tested and the conclusion discusses the achievements, shortcomings and direction of the further work.
