Prediction of foundation settlement of high-rise building using the finite element method
Červenka, Jan ; Dobrovolský, Ján (referee) ; Chalmovský, Juraj (advisor)
The focus of this thesis is to deal with reverse engineering of high-rise building settlements. This is modeled via the finite element method performed in the Plaxis 3D program. In the first part of this thesis, a calibration of input parameters of an appropriate material model – Hardening soil – is conducted. This calibration is a result of oedometric test data which were obtained within a geotechnical survey. An influence of soils over consolidation affecting calibration and the material model choice is described. Final values of reference stiffness parameters are used in a mathematical model of the focused area. This model is created for one half of the high-rise building plan, including vestibule. The high-rise building is founded in a foundation pit. The foundations of this building consist of raft foundation and piles of jet grouting. In the model, there are also changes in pore pressure during an excavation of foundation pit included. The functional model is used for parametric analyses, namely examining cases of object´s foundations and the possible influence of foundation pit´s symmetry on the object´s settlement. All the calculated processes in the object´s settlements are then compared to data obtained from geotechnical monitoring of the structure.

Digitizing of exhaust piping
Janečka, Karel ; Koutný, Daniel (referee) ; Paloušek, David (advisor)
This bachelor thesis deals with the possibilities and practical use of 3D scanning systems for engineering. The work includes the distribution of basic facilities for 3D digitizing, and their basic properties. The aim of this work is familiar with the procedure in reverse engineering, which is demonstrated on a specific example, the digitization of the exhaust pipe, using the 3D scanner Atos I and CAD system CATIA.

Replica of a historical machine gun mount
Doležal, Jakub ; Suchý, Jan (referee) ; Maňas, Pavel (advisor)
This bachelor's thesis deals with the analysis and construction of the Královopolská gun mount replica, which were equipped in selected objects of Czechoslovak border fortifications before the World War II. This work is devoted to the analysis of the original documents for the gun mount, CAD model creation, 3D scanning and modification of scanned polygonal mesh of the heavy machine gun vz.24, which was selected as an example of machine guns mounted in the Královopolská gun mount. This is followed by a virtual compatibility check of the gun mount model with the machine gun model. The production model creation is introduced in next part, using technology with the lowest possible production costs. Complete drawing documentation for the replica production is also part of this bachelor thesis.

Analysis of C Code for Testing of Decompilation
Dítě, Viktor ; Kolář, Dušan (referee) ; Matula, Peter (advisor)
The goal of this thesis is to extend framework for creation of regression tests with new functionality for analysis of C code. This framework is created in Python language and uses clang compiler for analysis of source code. The thesis contains description of area of reverse engineering and decompiler developed in AVG company. Then the area of software testing and C language are briefly introduced. Following chapters describe proposed and implemented extensions. These extensions are presented in sample tests. Summary of the results can be found in conclusion.

Production of castings using Rapid prototyping
Baránek, Martin ; Myška, Martin (referee) ; Bořil, Petr (advisor)
The work is focused on the production of a decorated stand casting using rapid prototyping and reverse engineering methods. The thesis first performs a literature search dealing with selected additive technologies usable for the production of foundry patterns or molds. Subsequently, the work describes the basics of 3D scanning technology. The experimental part of the thesis describes the production process of castings. The original was first digitized using a hand-held scanner, the obtained data were modified as needed and served as an input for 3D printing of permanent foundry patterns. Their production took place on a FDM 3D printer PRUSA MK3S and they were made of PLA material. The models were then formed into sand molds. The resulting castings were made of grey cast iron.

CAD design of the Walther PPS M2 laser sight housing
Macků, Veronika ; Hejtmánek, Petr (referee) ; Vančura, Jan (advisor)
The aim of this thesis is to create a housing for a laser-sight for a Walther PPS M2 pistol with the aid of reverse engineering methods. The first part is a research about laser-sights. The second part contains contemplation about the problem, mainly the restrictions brought on by the design of the Walther pistol and of the energy source of laser-sight Streamlight TLR-6, as well as the chosen production method of the housing, which is 3D printing. The main part describes the acquirement of input data via scanning the body of the Walther pistol and the housing of TLR-6, the making of the CAD design of the housing, the printing of a prototype with a 3D printer and the consequent correction of the CAD model on the basis of analysis of the prototype.

Extraction of Static Features from Binary Applications for Malware Analysis
Pružinec, Jakub ; Hanáček, Petr (referee) ; Kolář, Dušan (advisor)
Podoby škodlivého software sa deň čo deň menia a vyvíjajú. Vzniká tak nutnosť jednostaj tvoriť, aktualizovať a zlepšovať metódy na analýzu škodlivého software. Jedným z možných prístupov ako bojovať proti škodlivému software je klasifikovať ho na základe určitých statických charakteristík. Táto práca sa zaoberá návrhom a extrakciou týchto čŕt z binárnych spustiteľných súborov. Cieľom tejto práce je obohatiť nástroj na extrakciu statických rysov o extrakciu nových rysov a overenie ich účinnosti pri klasifikácii škodlivého software. Nástroj je vyvíjaný v spolupráci so spoločnosťou Avast, kde sa používa v systéme zhlukovej analýze.
