Enhancement of Decompilation by Using Dynamic Code Analysis
Končický, Jaromír ; Zemek, Petr (referee) ; Ďurfina, Lukáš (advisor)
As a part of the Lissom project, a retargetable decompiler is being developed. Its main purpose is to decompile programs for a particular microprocessor architecture into a high-level programming language. In present, methods of dynamic code analysis are not used during decompilation. However, we can significantly improve the decompilation results by using these methods. Design of dynamic-analysis methods is the main task of this thesis. In this thesis, reverse engineering and Lissom decompiler are described. Furthermore, general dynamic analysis methods, such as instrumentation and emulation, are described. The information we can obtain by using dynamic analysis and its usage during decompilation is proposed.

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.

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.

Increase of Charging Efficiency of 140kW CNG Engine
Hadrava, Martin ; Vančura, Jan (referee) ; Svída, David (advisor)
The master’s thesis is focused on flow analysis work filling in turbocharged CNG engine. The research method is reverse engineering. The intake canal is casted and than scanned by 3D Scanner ATOS. The CAD model is created in program Creo Parametric 2.0. In the created interactive model is simulated flow in the CFD program Star CCM +. The air intake system is modified for increasing the charging efficiency of the engine.

Design modification of the vehicle upright
Coufal, Jiří ; Blaťák, Ondřej (referee) ; Vančura, Jan (advisor)
This master´s thesis deals with design modification of specific upright in response to exchange the caliper for non-series one. It focuses on the creation and subsequent adjustment of the 3D model based on obtained size and shape of real upright by using 3D scan. For the editing part is conducted the strength test by using FEM and the results are compared with the values of the original upright.

Design of system model of L23 Blanik sailplane
Šenkýř, Miroslav ; Mališ, Michal (referee) ; Urík, Tomáš (advisor)
The aim of this diploma thesis is to create useful reference models of the glider L-23 Super Blaník and their use for framework proposal technology of production, which will improve accuracy and reduce labor intensity of production. The introduction of the thesis describes history of glider and historical overview of geometry transmission in terms of structure. The next chapter of the thesis deals with the description of reference models and rules of their creation. Section describing coordinate systems is closely linked with the previous chapter. Another section of thesis is dedicated to the importance of reference models in the product lifecycle. The creation and tuning of reference models of glider is described in the next chapter of thesis. The penultimate chapter deals with experiment, which allowed verification of reference model and product. The conclusion of the thesis describes proposed technology of production where used verified reference models and modern tools of CAD systems refine and facilitate production. The main objective in designing of reference models was the definition of high quality and usable surfaces. Also proposal technology of production was processed in order to ensure the improvement and simplification of manufacturing process.

Design of airframe mold for ultra-light aircraft manufacturing
Zatočilová, Aneta ; Dočkal, Aleš (referee) ; Paloušek, David (advisor)
This diploma thesis deals with digital data processing during the design of a mould of ultralight airplane airframe. The final digital model meets the demands on manufacturability by using CNC machining. The realization, in compliance with the reverse engineering approach, was conceived in four phases, which had to be solved step by step in order to preserve the continuity of the process. The phases correspond to the main chapters of the practical part of the thesis. The first part is focused on 3D digitalization of airplane fuselage by using an optic scanner ATOS and photogrammetric system Tritop. The result of this part is digital data of fuselage geometry in form of polygon grid. Next part deals with software reconstruction of collected data – by optimizing polygon grid in order to provide suitable base for surface modeling. The third part, the most time demanding, handles the creation of airplane fuselage surface model. Geometry has to satisfy requirements for smoothness and tangential or curvative connection of surfaces, including other requirements resulting from model usage. The final part of the thesis documents the procedure of deriving a mould from the aircraft fuselage geometry.

A car prototype manufacture using modern methods and CAD/CAM
Horák, Aleš ; Zouhar, Jan (referee) ; Sedlák, Josef (advisor)
The project developed under the engineering studies, solves the problem of production of a prototype car using modern technology, reverse engineering and CAD / CAM. Based on the literary study of the issue, was designed process of digitization of the physical model of car, including the treatment and processing of data. Follow-up step was to verify the production of the additive rapid prototyping technology - FDM method. Verification of the results was performed on a vertical milling cantilever FV 25 CNC with control system Heidenhain iTNC 530 using a cutting strategies by PowerMILL CAM software. At the end of the resulting models edit as necessary.
