Research aim – determine kinematic parameters features of best European swimmers in 50 and 100 meters freestyle swimming. Hypothesis − distance traveled under the water overcoming features has same influence for adult and junior swimmers 50 and 100 meters freestyle swimming. Objectives of the study: 1. Assess kinematic parameters features of best European swimmers in 50 and 100 meters freestyle swimming. 2. Compare kinematic parameters features of best European Adult and Junior swimmers in 50 and 100 meters freestyle swimming. 3. Assess kinematic parameters features interaction between each other and sport results in 50 and 100 meters freestyle swimming. Conclusions: 1. The time that it takes to for the swimmer to leave the block and distance traveled under the water of European Adult and Junior swimmers in 50 and 100 meters freestyle swimming does not differ significantly. 2. Adults of European championship were better and significantly correlated in all researched parameters except distance traveled under water in 50 m freestyle. 3. Distance traveled under water negatively influenced start distance speed of both adults and juniors in 100 meters and adults in 50 meters freestyle swimming.

Tato práce popisuje další vývoj výukového sériového manipulátoru se třemi stupni volnosti. Práce se zabývá jednoduchou mechanickou úpravou manipulátoru, ale především pak softwarovou částí. Výsledkem je pak hra piškvorky, kdy manipulátor umožňuje hru proti lidskému protějšku. První část práce je věnována zlepšení inicializačního procesu manipulátoru a následně pak i návrhem vhodné polohové regulace. V další části je manipulátor rozšířen o jeden stupeň volnosti. Součástí je i návrh koncového efektoru vhodného pro psaní. Z takto upraveného manipulátoru je sestaven kinematický model vhodný pro real-time řízení. Dalším krokem v práci je návrh samotné aplikace hry piškvorky. Je navržen vhodný hrací algoritmus, včetně detekce a rozpoznání znaků v hracím poli pomocí kamery. Následně je vše implementováno do real-time aplikace, kde komunikaci s uživatelem zajišťuje navržené uživatelské rozhraní.

This paper deals with techniques for acquiring data for character animation driven from video. Among other, it also presents several Motion Capture systems and animation data formats BVH and CSM. It also contains an example application demonstrating attained accomplishments. These are reviewed and there is instituted a course of future proceeding.

This master thesis is focused on Modular Self-Reconfigurable Robotic Systems. Their description is made at first and then possibilities of their use are listed. The next chapter concerns Molecubes modular system. The design of similar system where the construction of the individual modules is described follows. The transformations of coordinated systems in the individual modules are described and the calculation of forward kinematics and simulation of inverse kinematics is made at the end of the thesis.

The aim of the thesis is to propose and make a robot, which is made of identical modules. These modules are able to connect or disconnect themselves and thanks to this feature new structures of robot can be achieved. This problem is solved by the design proposal of a module, which is capable to rotate in two axis and has connection connectors for other modules. Communication is carried out by Wi-fi connection to the computer and angles required for reconfiguration are calculated by inverse kinematics in Matlab program. On these modules the reconfiguration test was succesfully demonstrated.

Title: Influence of the breathing muscles using POWERbreathe. Objective: The main object of this thesis is to determine, if it is possible to use 3D kinematic analysis to measure changes of trunk shapes during quiet breathing and breathing when using POWERbreathe and if it is possible to identify the changes. The thesis is divided to two parts. The first part contains theoretical part, focused on issue of kinesiology and biomechanics of breathing. The special part is concentrated on research, where I find changes of trunk kinematics during application of POWERbreathe. Method: Measurements were made on 6 probands in the same age category (women), when each measurement was performed during quiet breathing, maximum inhale/exhale, resistive breathing when using POWERbreathe and then another quiet breathing and maximum inhale/exhale. Quiet breathing was chosen as benchmark. The experimental measurements was done during one day. The research was used 3D kinematic motion analysis using system Qualysis. Were observed changes in the shape of the trunk and possibly caused breath changes during using POWERbreathe. Results: Measurements has confirmed, that the system Qualysis is able to detect mobility and the trunk shape changes. At a certain threshold load device POWERbreathe prevailed movements cranial...

Author: Barbora Říhová Title: Kinematic Analysis of Gait in Patients with Hip Osteoarthrosis Objectives: The aim of this thesis was to analyse the gait patterns in probands with Stage III osteoarthritis of the hip joint, to compare these patterns with published norms and to confirm a set of pre-established hypotheses. Method: The thesis was designed as a case study, the purpose of which was to observe changes in the pelvis and trunk extension during gait, associated with significant degenerative changes in the hip joint. A total of 9 probands with Stage III osteoarthritis of the hip joint (6 females, 3 males) took part in the study. A complete physiotherapy assessment was carried out as part of the study. The temporal gait parameters were used to measure the probands' walking speed and relative stance phase duration. The following variables were measured in the frontal plane: lateral displacement of the pelvis and trunk toward the stance limb (cm) and pelvic obliquity toward the swing limb (degrees). A 3D motion analysis and evaluation of kinematic parameters were carried out using the Qualisys motion capture system device consisting of 6 infrared cameras. Gait was measured at different walking speeds during a 10-second time frame and the data was subsequently subtracted from a minimum of 5 gait...

Supervisor's e-mail address: Dana.Mandikova@mff.cuni.cz Abstract: This thesis is a follow-up to the bachelor thesis titled Book of problems of kinematics of mass point for students of Physics Education. This work is a part of wider project which aim is to create an electronic collection of problems completed with detailed solutions and structured hints. Within the frame of this work was made part of collection with forty problems, which theme is kinematics of mass point. Most of problems were chosen from already existing collections and textbooks. Each problem contains task, system of hints and resulting solutions of hints, detailed solution and answer. At the beginning of the work are given aims of the work and its structure. In the next part of work is mentioned a survey of curriculum which is instructed in lower and upper secondary school and university in brief, which relates to this theme. The next part is a survey and brief characterization of collections of problems with this theme. The fourth part of the work is devoted to the electronic collection of problems, its history, the technical elaboration of problems, there is described the...
