Parametric 3D Models
Ondrejó, Michal ; Kolář, Martin (referee) ; Zemčík, Pavel (advisor)
The aim of this work is to propose possibilities of interconnection of objects in parametric model. Individual options are implemented in the parametric three-dimensional modeling system. This system allows the creation of models using various geometric operations, change parameters at any time, animate the created model, and save the parametric model in a human-readable format. The proposed solution was implemented and evaluated on simple example.

Methods for the evaluation of postural stability
Nevěčná, Leona ; Janoušek, Oto (referee) ; Koťová, Markéta (advisor)
This study deals with methods for evaluation of postural stability. The main problem of posturography is lack of standardization in measurement and evaluation. There are presented some parameters affecting postural stability that are often taken into account. Those are parameters that might be changed while measuring, for example standing position, sampling duration or visual control. And others that are altered when evaluating is taking place, variability of those parameters, is much greater. Measurement protocol taking into account the most promising parameters was put together based on literary search. Changes in COP of ten subjects were measured with Wii Balance Board, according to the proposed measurement protocol. The data acquired from a particular subject were used to count values of parameters used in evaluation. After that the values were statistically analyzed. To compare each parameter, trajectory with good results according to other literature was chosen to pose as a reference. Final result is comparison firstly between importance of changes in parameters of measuring and secondly between success of detection of those changes of separate parameters.

Competition Aircraft Model Tail Design
Hub, Pavel ; Šurkala, Martin (referee) ; Matějů, Jiří (advisor)
This bachelor’s thesis deals with an empennage design for a new competition aircraft. The introduction gives an overview of the Air Cargo Challenge 2019 competition and conceptual layout of the aircraft. The research part of the thesis is focused on possible tail configurations, tail parameters and a statistical analysis of commercially made aircrafts. The most suitable configurations are then compared in detail, during which basic longitudinal stability calculations are done. In the last part, load is calculated, followed by structural design and bearing components sizing.

Speed Increasing of the Střelice - Moravský Krumlov Section
Dvořák, Jiří ; Šiške, Vladimír (referee) ; Hruzíková, Miroslava (advisor)
The aim of this thesis is to examine the possibilities of increase of speed on a railway track section between Střelice and Moravský Krumlov. The increase of speed is examined according to contemporary geometric parameters of the railway track. Sporadically an assessment with proposed changes of geometric parameters of the railway track is conducted. The proposed changes cannot cause any profound transformations of the body of the railway track. In both cases a restriction of speed by level crossing, a track branching and position of semaphores are taken into consideration. A proposal is elaborated with help of an overview of railway top.

Biomass for power plants in the off-grid operation
Roule, Jaroslav ; Radil, Lukáš (referee) ; Baxant, Petr (advisor)
The thesis discusses the use of biomass for electricity island operation. The first chapter explains the concept of biomass and its distribution. It also shows the potential and availability of biomass. The second chapter describes the transformation of biomass into a suitable fuel form. The third to fifth chapter describes the conversion of biomass as a fuel into electrical energy through combustion, Stirling and steam engine. In these chapters there are brought the following parameters and prices of these motors and single-phase and three-phase alternators that can be connected to these engines. Other chapters describe the production of electricity in line with consumption, where the cost per hour to run engines for the various types of fuel and price of the electricity produced in kilowatt hours is calculated. In the last chapter of the thesis there is described the possibility of accumulation of electrical energy.
