Optimization of dimensions of the base frame to form for large castings
Mottl, Jan ; Navrátil, Petr (referee) ; Skalka, Petr (advisor)
In this thesis the problem of optimizing the dimensions of the base frame molds for casts with FEM and for 4 weight classes, ie casts weighting 1, 3, 5 and 10 tons is solved. For the evaluation of the FEM ANSYS program was used. There are gradually presented optimization procedures for all four weight classes. There was established the persistence of forms and frame and at the end the conclusion of the technical-economic evaluation of the proposed forms in terms of material savings in comparison to the current state of production was made.

Technology project and layout for holder
Mottl, Jan ; Žák, Ladislav (referee) ; Rumíšek, Pavel (advisor)
Technology project and layout for holder. Bachelors thesis of the bachelor’s studies the 3rd year. School year 2008/2009, education group 3P1. FSI VUT in Brno. Institute of technology, department of forming. April 2009, pages 47, pictures 28, tables 2, supplements 9. Bachelors thesis which was elaborated in the frame of the bachelor’s studies branch 2307 submitting the technology project and layout of the holder. Component are produced from material 11 321 using of undermentioned literature pursuit a problem of the select material, sheet metal cutting and bending which was designed by cutting with processual tool and bending tool. At designed cutter and bending was used of standardised components. Project organization of production is designed so, to keep up produce of requisite series in a year.

Research of polymeric composites based on biological filler solved by experimental approach
Mottl, Jan ; Müller, Miroslav (advisor) ; Hrabě, Petr (referee)
The thesis is focused on research of polymer composites with natural fibers. The theoretical part is an introduction to composite materials with a focus on natural fiber reinforcements and polymers. For the needs of the experimental part of the work also deal with theoretical issues of bonded joints. Experimental part deals with the influence of natural substances added to the bond formed polymeric adhesive and the resulting composite. Made composites were tested and evaluated from the mechanical and technological-economic terms.

System for preparation, realization and evaluation of tests
Mottl, Jan ; Pecinovský, Rudolf (advisor) ; Hamendi, Mohammed (referee)
The thesis focuses on the design and implementation of the system for preparation, realization and evaluation of tests. The objective was to analyze tests and textual format for import of these tests to Integrated Study Information System of the University of Economics. The next objective was the implementation of the student testing system based on the analysis. The last objective was writing user manuals. In the beginning there are briefly described concepts associated with teaching supported by information technologies and electronic testing. Then the analysis of tests and textual format for import of these tests is performed. From the analysis system requirements are derived. The thesis then describes the design and implementation of the system and user manuals for teach-ers and students are written. The contribution of the thesis is implemented student testing system that facilitates preparation of tests mainly for teachers who teach at more schools than just at the University of Economics.
