Code Analysis and Transformation
Křoustek, Jakub ; Masařík, Karel (referee) ; Meduna, Alexandr (advisor)
This paper describes methods and procedures used for code analysis and transformation. It contains basic information of a science discipline called reverse engineering and its use in information technologies. The primary objective is a construction of tool that can disassemble from binary form to symbolic machine code. This operation is highly dependent on the concrete instruction set, and it has to be used for a beforehand known processor architecture. This problem is solved with patterns, plug-ins, and modularity of disassembler. These features provide users the ability to add new instruction sets into this disassembler. The output is the text representation of instructions and is functionally equivalent to the in-put. The thesis demonstrates usual methods of disassembly as well as the methods made by the author.

Use of 3D technology in foundry industry
Straka, Pavel ; Krutiš, Vladimír (referee) ; Pernica, Vítězslav (advisor)
The work is focused on replacing a faulty briefcase handle with an aluminium substitution. The handle is fabricated with the help of reverse engineering, where the handle is scanned with a 3D scanner. With that information, a model copy of the part is made, which is 3Dprinted from PLA and PolyCast materials. These handles are used as expendable models, which are used for casting using an “investment casting” method. Those are made from an AlSi10Mg alloy. Theoretical part deals with additive technologies, which are mostly used for manufacturing of foundry models and moulds. Next, the basic principles of 3Dscanning are described, and the term reverse engineering is also explained.

The Production using 3D Printing of Fixture for Shaping Plastic Pipes
Tretera, Robin ; Sedlák, Josef (referee) ; Kalivoda, Milan (advisor)
This Bachelor thesis compares two options in production of shaping form for plastic pipe - handmade production versus 3D print technology (specifically DMLS method). The thesis contains detail description of the final part and shaping form with pros and cons of both production methods. Handmade production is more suitable for serial production with its lower price. In time pressure 3D printing comes up with its fast and repeatable results.

Assembling and Functional Verification of a Home 3D Printer
Tesař, Jaroslav ; Zouhar, Jan (referee) ; Sedlák, Josef (advisor)
This thesis was created as a bachelor project in the Faculty of Mechanical Engineering at VUT in Brno. In the theoretical part, the additive technology Rapid Prototyping is introduced together with the most common methods, followed by the assessment of advantages and disadvantages of the new technology and its possible uses in various fields of human activity. In the experimental part of the diploma thesis was assembled and the printing parameters were set. Consequently the comparison models were printed on the 3D home printer and on professional printer Dimension uPrint. The accuracy of the printers is compared. The thesis concludes with the analysis of technical and economical parameters.

Usage of 3D scanning in precise injection moulding
Chylík, Michal ; Čudek, Vladimír (referee) ; Zatočilová, Aneta (advisor)
The aim of this bachelor thesis is creating a complex study on the topic of 3D scanning and reverse engineering regarding technical praxis. Part of this bachelor thesis are three examples of usage. Using 3D scanner for reconstruction of plastic parts in marketing praxis, specifically for recovering of missing data and subsequent valuation. Using 3D scanner as an inspectional tool - a support for measurement of quality of plastic moulding. And last but not least an option of creating an identical part to fit requirements of tool shop. The drawing documentation including protocol for inspect and 3D models are included in the thesis.

Automated UML Class Diagrams Generation
Brázdil, Martin ; Bartík, Vladimír (referee) ; Kreslíková, Jitka (advisor)
This master's thesis describes the analysis, design and implementation of an application for automatic generation of UML class diagram. Application is designed as a web service, which provides remote access, especially permanent actuality of generated class diagram. Input of the service is a compiled application written for C# .NET or Java platform. The reader is acquainted with basics of reverse engineering of mentioned platforms and with structure of UML class diagram. Then are these knowledge applied in design and implementation of the service. The main goal is to facilitate and accelerate the activities of software development team members.

Application of modern technologies for the production of the release mechanism of a car door
Hruška, Lukáš ; Dvořáček, Jan (referee) ; Sedlák, Josef (advisor)
The Bachelor`s work concerns the production of door ulocking mechanism for a passanger car Renault Megane. From the viewpoint of function and the necessity to keep the exact dimensions of chosen parts were the data for the production obtained by digitalization of a real product. The digitalization was carried out by the contactless optical 3D scanner of GOM mbH company, specifically the developmental series ATOS II Triple Scan. The pin`s data were obtained from parametrical program Autodesk Inventor 2011. For the production of Master models the additive technology Rapid Prototyping, method Fused Deposition Modeling, was used. Master model of the handle was used for the production od solicon mould, that was used for casting of required number of handles from resin. The end of the work deals with a technical and economical assessment of the production. A part of the work is also a summary of the most used methods of Rapid Prototyping and Reversible Engineering.
