Počítačová simulace pohybu a plánování trajektorie mobilního robotu. / Mobile Robot Path Planning Simulation and Calculation.

Koch, Zdeněk January 2008 (has links)
This thesis deals about design and realization software application "Mobile robot studio" for planning path mobile robot in pseudo 3D world. It contains several tools, witch most important are: simulation control, path planning, world editor and commands editor for CAN. Application was made by technology .NET 2.0 and for 3D design was used Microsoft DirectX 9 API. This thesis has been supported by the Czech Ministry of Education in the frame of MSM 0021630529 Research Intention Inteligent Systems in Automation.

Plánování optimální trajektorie letadla s překážkami / Path Planning of Airplane with Obstacles

Očenáš, Marek January 2013 (has links)
The aim of this master's thesis is the implementation of optimal trajectory planning for an airplane flying in lower altitudes, which has to avoid collision with obstacles. For the planning we assume static and fully known environment. There are described principals, optimality and complexity for some chosen methods of planning in this thesis. And based on the methods' characteristics it's chosen the best method for implementation.

Vektorové letecké mapy s "high a low trajektoriemi" / Vector Based High and Low En-Route Aeronautical Charts

Latta, Martin January 2016 (has links)
Tato diplomová práce se zabývá dynamickým vykreslováním vektorových leteckých map, především letových trajektorií a navigačních bodů do mapy. Mapy jsou integrovány do mobilních aplikací, které piloti používají během letu a které nahrazují původní papírové mapy. Práce obsahuje teoretický úvod do problematiky a základní pojmy používané v letectví a navigaci. Další částí práce je průzkum, popis a zhodnocení existujících řešení a aplikací společně s návrhem a designem nového řešení. Nakonec je prezentována implementace demo aplikace pomocí WebGL knihovny a výsledné vyhodnocení a porovnání.

Vliv senzomotorickych vložek na posturální stabilitu dětí s dětskou mozkovou obrnou. / Effect of sensomotoric insoles on postural stability in children with cerebral palsy

Bartošová, Simona January 2022 (has links)
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...

Application of center-out k-space trajectories to three-dimensional imaging of structure and blood transport in the human brain

Shrestha, Manoj 26 September 2016 (has links) (PDF)
A novel non-invasive imaging method of unique k-space trajectory named “3D center-out EPI with cylindrical encoding” was developed and implemented for fast imaging of the human brain. The method based on a variant of 3D hybrid EPI combines advantages of the Cartesian and the radial encoding to achieve ultra-short echo time independent of spatial resolution and reasonably short echo train length yielding a quality image of high signal-to-noise ratio. Unlike rectilinear sampling, the method offers not only less motion and flow artifacts but enables also the undersampling capability. As a result, the method improves temporal resolution by shortening the measurement time. Nonetheless, artifacts induced from long-term drifts of the magnetic field as well as geometrical distortions caused by B0 inhomogeneity were removed with the average phase of the k-space center lines and an additional field map scan. Compared to other cylindrical k-space trajectories based on echo-planar imaging, which lead to progressively increasing echo time upon increasing the spatial resolution, the proposed method offers more benefits. As a significant application, imaging readout of the novel technique was applied to true 3D cine imaging which was later used in the combination of pseudo-continuous arterial spin labeling module in order to track a short arterial spin labeling (ASL) bolus of well-defined length along the fast passage through the large vessel compartment of the brain. Parametric maps of ASL signal change, estimated time-to-peak and ASL bolus width were extracted in order to characterize the macrovascular compartments of the brain-feeding arteries. Consequently, bolus dispersion within a single arterial branch was also assessed.

Fyzika nebodových objektů v silných gravitačních polích / Physics of extended objects in strong gravitational fields

Veselý, Vítek January 2019 (has links)
We study several different models of extended bodies in gravitational fields. Firstly, we revisit the glider model of a dumbbell-like oscillating body. We develop an independent scheme to integrate the equations of motion. We study the radial fall of a Newtonian spring, calculate the position shifts of the spring and find the critical value of the spring constant which cannot overcome the tidal forces. We argue that the relativistic glider model is unphysical due to its behaviour in the critical regions. Secondly, we show that Dixon's theory of extended bodies predicts a geodesic motion of the centre of mass in maximally symmetric spacetimes. We prove that a system of test particles can be described by a conserved stress-energy tensor and we evaluate the position shifts of the glider model in the maximally symmetric spacetimes, showing its disagreement with Dixon's theory. We thus conclude again that the glider model must be rejected. And thirdly, we study a model of an extended body consisting of interacting particles, which is in accord with Dixon's theory. We calculate the position shifts for this model and show that the model does not predict any measurable swimming effect. Finally, we estimate the numerical error of the calculation by finding the position shifts of the model in maximally symmetric...

KŘIKLÁNOVÁ, Lenka January 2012 (has links)
This thesis deals with the analysis of motion trajectories on the selected segment of population within the urban system of the town České Budějovice. The analysis is based on collecting primary data from longitudial survey carried out in order to find and to generalize some repetitive patterns of spatial behavior of selected population in different periods. Other aims are to indentify their typical social situations and to structure characteristics in the urban system of the town České Budějovice.
