Effect of sensomotoric insoles on postural stability in children with cerebral palsy
Bartošová, Simona ; Hráský, Pavel (advisor) ; Gryc, Tomáš (referee)
Author: Bc. Simona Bartošová Title: Effect of sensomotoric insoles on postural stability in children with cerebral palsy Objectives: Objectively assess the effect of sensomotoric insoles on children with cerebral palsy (CP) via COP (Centre of Pressure) parameters recorded on Kistler force plate. Methods: This thesis is designed as an experimental study. Selected paramaters of static postural balance were recorded via force plate to assess the effect of sensomotoric insoles. Five subjects (average age 7.2 years) with diagnosis of cerebral palsy were enrolled into the study. Data collection was carried out in two separated sessions - first before therapy and second after using the insoles for one month. The validity of the data was supported by three repetitions for each modification - upright plain stand with open eyes, upright stand with feet together and upright plain stand with closed eyes. Monitored parameters were: total trajectory of COP, amplitude of mediolateral displacement of COP, amplitude of anteroposterior displacement of COP and mean velocity of movement of COP. The data were analyzed in MATLAB® version R2019b. The statistical analysis was performed including the outliers elimination. The normality of data was checked by Lilliefors' test. In the case of normality a two-sample Student's...

Nonparametric tests of independence between animal movement trajectories
Veselý, Martin ; Dvořák, Jiří (advisor) ; Omelka, Marek (referee)
In this thesis, we assume observing a pair of trajectories of two objects which could interact with one another and we want to propose a way to test their independence. We formulate basic point process definitions and discuss ways to describe trajectory data. We formulate the theory behind Monte Carlo tests and global envelope testing. In Chapter 2, we propose a parametric model to represent trajectories and derive Maximum Likelihood estimates of its model. We conclude the chapter by exploring the performance of these estimates. In Chapter 3, we propose test statistics used to test for independence using a nonparametric Monte Carlo test based on a random shift approach. We perform a simulation study to assess the performance of these statistics under various conditions and discuss the selection of fine-tuning parameters. Finally, in Chapter 4, we study real data provided by the Voyageurs Wolf Project and apply the proposed tests on real wolf trajectories. 1

Platform for Measurement of Atmospheric Quantities
Hanák, Jiří ; Vlk, Jan (referee) ; Chudý, Peter (advisor)
This work is dealing with the design and implementation of an embedded system for aerology measuring. The aim of the system is to monitor atmospheric states during an ascent in the suspension under an meteorological balloon. First of all, attention is given to the Earth's atmosphere and its quantities, then an overview of existing systems for performing aerological measurements. The core of the work is focused on the choice of measurement techniques and the selection of suitable measuring elements for a given scenario. The aerological probe is using atmospheric sensors HIH-8131-021-001, MS5611-01BA03 and PT1000-550 for temperature sensing, while GNSS data is received using the MAX-M8Q-0 module and the measured data is stored on a microSD card and transmitted in parallel using the MTX2-434.650-10 radio module. The system is controlled by STM32L1 from STMicroelectronics programmed in C using HAL abstraction layer.

Simulation of a Golf Ball Trajectory from Video
Hlobil, Marek ; Ševcovic, Jiří (referee) ; Chmelař, Petr (advisor)
This work deals with the golf ball flight simulation based on video recordings. The way how to determine the trajectory of a golf ball using several initial points is described here. For the ball recognition there are used computer vision techniques, particulary pattern recognition. The work covers physics of the golf ball, it deals with physical influences that occurs during the ball flight and it tries to describe the trajectory approximation.

Computer graphics flow visualization methods
Častulíková, Veronika ; Štefan, David (referee) ; Urban, Ondřej (advisor)
Flow visualization is one of the important topics in the scientific visualization, which is a subject of ongoing research. Data obtained by numerical simulations are further analysed to gain a better understanding of fluid flow. With the rapid development of computational simulations, demand for more advanced visualization methods has grown. Basic overview and a detailed description of the fluid flow visualization techniques is introduced in the bachelor thesis. Afterwards, the techniques are applied on data obtained by CFD simulation of a vortex rope in the draft tube swirl generator.

Evolutionary Design of Moving Objects
Fajkus, Jakub ; Schwarz, Josef (referee) ; Bidlo, Michal (advisor)
The aim of this work is to implement a system for automatic evolutionary design of virtual robot controllers. In particular, Linear Genetic Programming representation combined with a steady-state genetic algorithm will be used to find a suitable program that will lead a given virtual robot across a sequence of points denoting a predefined trajectory. The MuJoCo physics engine is applied to allow the user to specify the robot shape and to evaluate its behavior according to candidate programs generated by the genetic algorithm. The goal is to train the robot to follow the given path by optimizing the distance of the robot from the given points during the simulation. The optimization is performed by evolving the programs for a given number of generation of the genetic algorithm. Several sets of experiments will be presented and obtained results will be evaluated.

Hamilton's function in classical and quantum mechanics
Černý, Jiří ; Svítek, Otakar (advisor) ; Žofka, Martin (referee)
In this work we will examine an on-shell action, its basic properties and its relation to transition amplitude. Derivatives of on-shell action with respect to position and time are equal to momentum and energy. On-shell action of a system is sufficient for determining the trajectory describing time evo- lution of the system. On-shell action can be computed as (off-shell) action of specific physical trajectory connecting initial position in initial time with final position in final time but it can also be found from solutions to two Hamilton-Jacobi equations, one in initial time and position variables and the other in final time and position variables. In quantum mechanics a transition amplitude is directly proportional to the complex exponential of the on-shell action. Work with on-shell action is demonstrated on examples such as free particle, harmonic oscillator and partly also on central force problem.
