Forensic Identification of Child Faces
Klíma, Ondřej ; Španěl, Michal (referee) ; Beran, Vítězslav (advisor)
This thesis is focussed on children's faces comparison. Its aim is to create the application providing functions for photocomparison and ageing. Both these parts work with portrait photos of children. Photocomparison purpose is a metric expression of similarity of two portraits independently on their age. Ageing is a tool for the simulation of an individual's growing old on the photo. Principles of both functions are based on geometric morphometry methods, particulary on procrustes analysis and thin-plate spline aproximation.

Level of Detail (LOD) Algorithms in OpenSceneGraph Library
Koukolíček, Ondřej ; Kršek, Přemysl (referee) ; Pečiva, Jan (advisor)
The aim of this thesis is to explore and evaluate capabilities of the OpenSceneGraph library in the field of level of detail (LOD) algorithms. It contains introduction to the LOD issues and detailed description of techniques that are used in conjunction with this technology. Furthermore it analyses those tools available in OSG, which can be used to create an application utilizing LOD. The main part of the thesis is focused on description of design and implementation of application, which uses the LOD capabilities of OSG as well as own extension to these methods. In the conclusion, the resulting application is subjugated to a benchmark and the OpenSceneGraph librarys LOD capabilities are evaluated.

Design of Hand Blender
Kalenský, Ondřej ; Buganská, Tamara (referee) ; Sládek, Josef (advisor)
This bachelor‘s thesis deals with the design of ahand blender. The main problems it covers are designing with consideration to blind and old people, clear and natural control and more options for holding the device. The thesis discovers the essence of the process of blending and whisking. Based on this knowledge, the ambition behind the design of the product is to form anew shape which is in harmony with its function. The thesis is marginally focused on the theory of designing and developing anew product and it describes the practical usage of user-friendly design rules.

Combustion of a mixture of hydrogen and natural gas in the combustion chambers of boilers and gas turbines
Honzíček, Štěpán ; Kracík, Petr (referee) ; Milčák, Pavel (advisor)
Master‘s thesis specifically deals with very current topic of blending (low-emission) hydrogen and natural gas. A key view focus on combustion of a mixture hydrogen and natural gas. Preliminary part describes combustion of fuel gases in general and is followed by a technical search on construction of combustion chambers of boilers and gas turbines. It’s added information about current development and utilization of hydrogen. New projects of hydrogen combustion technologies are also introduced. Practical part shows a calculation of a gas mixture combustion balance in real conditions. It‘s extended by proposal and construction of a blending technology of hydrogen and natural gas with subsequent combustion in an uncooled combustion chamber. Concluding part includes a program for operating states calculating when the variables of introduced technology are changing.

Medical Data Rendering in Real-Time
Lengyel, Kristián ; Havel, Jiří (referee) ; Jošth, Radovan (advisor)
This thesis deals with design and implementation of an application for medical data imaging in real-time. The first part of project is focused on methods for obtaining data in medical practice and visualization of large volume data on computer using familiar rendering approaches. Similar applications are used outside of medicine in other fields, such as chemistry to display molecular structures or microorganisms. Another part of project will focus on benefits of visualization of volumetric data using programmable hardware and new methods of parallelization of algorithms on graphics card using CUDA technology, and OpenCL. The resulting application will display the volume of medical data based on selected method accelerated by programmable shaders, and time-consuming operations will be paralleled on graphics card.

A Night in the Mill
Topínková, Anita ; Havlíček, Jiří (referee) ; Zet, Martin (advisor)
Be moving, seek, hunt for sth, can´t find it so far, that is a promise of paradise, or a paradise itself. Mobility as a protest, pursuit of adventure, searching for escape, authenticity or identity.

Isolation of lignin from grape seeds and its application as filler for polyhydroxyalkanoates (PHA)
Vostrejš, Pavel ; Vítová, Eva (referee) ; Kovalčík, Adriána (advisor)
This diploma thesis deals with 1) the preparation of biodegradable polymer films based on polyhydroxyalkanoates (PHA) and 2) their modification by lignin as an active additive. The motivation for this work was to prepare active packaging material for food packaging. Polymer films were prepared by blending of neat crystalline poly(3hydroxybutyrate) (P3HB) and amorphous polyhydroxyalkanoate (PHA). The lignin was isolated from grape seeds derived from grape pomace. The solubility of lignin in chloroform was improved by acetylation. The properties of the isolated lignin were determined by elemental analysis, ash content, and infrared spectroscopy (FTIR). Lignin was used as an active additive for the modification of polymeric films prepared by solution casting of P3HB or P3HB blended with amorphous polyhydroxyalkanoate. The effect of different concentrations of lignin in the range of 1 to 10 % was tested. The lignin type and concentration had a different influence on the final thermal and mechanical behaviour of polymeric films. Lignin increased the values of the Young modulus and tensile strength of the prepared films. Differential scanning calorimetry data confirmed that lignin positively modified crystallization kinetics of P3HB. Thermogravimetry was used to analyse the thermal stability of PHA films. Lignin markedly increased the thermal stability of PHA films. However, acetylated lignin harms the mechanical properties of films. Moreover, this work showed that lignin isolated from grape seeds and added into PHA films proved its high antioxidant capacity. PHA films with lignin displayed much better gas barrier properties compared with PHA films without lignin. The prepared bioactive PHA films fulfil the requirements for sustainable food packaging with high antioxidant capacity and excellent gas barrier properties.
