Scientific reconstruction of the fossil marine amniots
Cettl, Karel ; Mazuch, Martin (advisor) ; Ekrt, Boris (referee)
To create a good scientific reconstruction is important artistic skills and knowledge of history painting of prehistoric animals, and also knowlages in the anatomy, zoology, palaeontology, palaeoecology and also biomechanics. Reconstruction It stands on the borderline between art and science. Our view on the fossil marine Amniotes change over time with advancing skeletal findings, and also changed a scientific reconstruction. Although the actual outputs, such as reconstruction and in particular 3D models can explain a number of new or unexplained informations about this group. A reconstruction expert can not only beautify their actions, but also enthance scientific knowledge, or even to outline a new direction for further research. Keywords: Scientific reconstruction, fossil marine amniotes, adaptation, anatomy, evolution, palaeoecology, biomechanice, 3D models, trends.

Watermarking 3D Models
Honzátková, Tereza ; Herout, Adam (referee) ; Španěl, Michal (advisor)
Goals of this work are to summarize the process and existing methods of 3D models watermarking, to choose relevant methods for embedding/extraction of a watermark to/from 3D models. The final solution is based on Spectral Mesh Compression technique. This method is robust, imperceptible and informed. The embedded watermark is detectable and robust against geometrical transformations, added random noise, mesh smoothing and simplification, compression and cropping. The realized tool allows a user to embedding watermark into the mesh, modify the mesh and extraction of a watermark from mesh. Testing was conducted on a set of 5 models differing in size, shape and density of points. The resulting tool inserts a watermark composed of four characters that can detect both undamaged models and the models affected. Among the attacks against which the watermark is robust, include transformations, rotation, scale, adaptive random noise, and combination of this.

Analysis of Defects on PCB Using Modern Optical Method
Vala, Martin ; Řezníček, Michal (referee) ; Řihák, Pavel (advisor)
This diploma thesis is focused on detecting of defects on BGA (Ball Grid Array) components using of X-ray. Defects are formed during reflow BGA components during assembly, but also later due to mechanical and thermal stress. Therefore, there is an overview of defects and methods of diagnosis of BGA packages eg .: modern X-ray defect detection or micro sections. There is disclosed a device NORDSON DAGE XD7600NT its operation and setup. The device enables advanced methods of scanning called X-plane. For creating 3D models used reconstructive software called CERA, which uses raw data from the method of X-Plane.

Temperature analysis of molded case circuit breaker's current path
Mejzlík, Tomáš ; Makki, Zbyněk (referee) ; Dostál, Lukáš (advisor)
The work deals with the preparation of dimensional drawings, circuit-breakers and switching elements for inclusion in the database devices. Part of the original drawing documentation is from the U.S. catalogue EATON. Preparation of drawings from the catalogue meant to convert the projection between U.S. and European, including compliance with ISO and ČSN, redraw geometry to the CAD system using Autodesk AutoCAD 2010 and complete dimension. Another part of the project was to model the two completely dimensioned breakers in 3D space, along with their implementation in the model EATON cabinet, including the construction of their connections to buses and cable entry.

Advanced Techniques Demo Using OpenGL
Buček, Antonín ; Přibyl, Jaroslav (referee) ; Herout, Adam (advisor)
This thesis demonstrates advanced techniques using OpenGL. The work is conceived as a demo without any size restrictions. It focuses on creating 3D world, which consists of inner rooms complex. Some additional interesting objects, lighting and shadows enrich the rooms. Particle systems, which were used to create explosions, smokes and some other particle effects are described in the thesis, too. 3D machine models fight between themselves using laser beams and form the story of the demo. Important part of the work is a movement model which is applied to both models and avatar. Sound track completes the demo.

Study of static behaviour of selected agricultural objects
Horský, Vojtěch ; Zídek, Rostislav (referee) ; Brdečko, Luděk (advisor)
This thesis deals with the study of static behavior of agricultural buildings, evaluating their existing state using two-dimensional and three-dimensional construction models. Elements that serve to improve static effects of constructions are implemented into these models or replace the currently used elements. Strains of the modified constructions are calculated are applied to qualify the implemented elements and designed joints.
