Design of 3D model for three flutes drilling tool for 3D printing
Bělaška, Karel ; Slaný, Martin (referee) ; Zemčík, Oskar (advisor)
This bachalor‘s thesis deals with the production of three flutes dril 3D model by Fused Deposition Modeling method. First part of this thesis describes geometry of twist drills and the methods of their production. In the main part of the thesis is described the creation of 3D model, that was created in software Inventor Professional 2016. There were two methods of creation used – grinding method and the dragging profile over helix method.

Use of Bayesian Networks in Managerial Practice
Rod, Martin ; Váchová, Lucie (advisor) ; Bína, Vladislav (referee)
The main goal of our bachelor thesis is to create a quantitave model which describes real biogas plant (property of company VOD Kadov) and its troubleshooting. Our created model has broad applications. It can be used as a support tool for managerial decision making either for biogas plant's malfunction or for its improvement. Secondly it plays a major role in quantitative clarification of inner links and processes which takes place inside the biogas plant. This quantification is done by Bayesian statistic approach via Bayesian network and its methods. For modeling purposes we exploit (leak) noisy OR-gate model and various methods for variable discretization. We heavily use company's data for model creation. With our model we simulated the run of biogas plant and its possible malfunctions. We also provided an easy step by step guide how to troubleshoot these malfunctions.

Trends in the design and creation of new materials
Rodrová, Veronika ; Gaff, Milan (advisor) ; Borůvka, Vlastimil (referee)
The objective of my research is to examine the influence of densified wood in combination with native wood on its mechanical properties such as moduls of elasticity, bending strength, limit of proportionality, bendability coefficient and tensile-shear strength of glued line.
The examined woods are Europen beech (Fagus Sylvatica L.) and Aspen (Populus tramula L.). The tests were carried out on speciemens with different thickness. The densification by 10% and 20% was performed. For the glued joint polyurethane adhesive and polyvinylacetate glue were used.
The thesis includes simulation of the properties, their computer program tetsing, and the comparsion with the values obtained from real measurement. The purpose of this part of thesis is to achieve a simulation that will replace laboratory tests or disprove this method of scientific research and deepen our knowledge of proceses occuring during the pursued way of stress.
