Person Identification Based on Locomotion
Pražák, Ondřej ; Richter, Miloslav (referee) ; Horák, Karel (advisor)
This paper deals with study of human movement and using that in identification. In the first part of my work are explained characteristics of human movement and factors which take effect on these characteristics. Practical part is dealing with design of program which is solving mentioned problems. The input of program is created by video sequence with lateral movement of human. The program is finding coordinates of lower limbs joints. From this coordinates are created locomotion characteristics used for human identification. Matching of time behaviors is based on correlation.

Filip, Jakub ; Lacko, Branislav (referee) ; Parák, Roman (advisor)
The aim of the bachelor thesis is the design and implementation of a control program for the mobile robotic platform TurtleBot3 Burger. The theoretical part of the bachelor's thesis defines the issue of mobile robotics, with a closer look at the various possibilities of locomotion, including examples from industrial practice. The TurtleBot3 mobile robot series belongs to the robotic platforms distributed by ROBOTIS, where their main feature is compatibility with the Robotic Operating System (ROS). The core of this system is licensed under the BSD, which guarantees open source code. The integration of ROS with the TurtleBot3 Burger model provides freely accessible robust libraries, which form the basis for understanding the control of a differentially controlled robot through ROS. In the practical part, the assembly and configuration of the robotic kit TurtleBot3 Burger is performed, including the introduction of key functionalities of this mobile platform, and the design of your own solution. The conclusion contains the justification of the mentioned proposal and the output after its implementation on a real robot.
Running in the context of developmental kinesiology
Růžek, Ondřej ; Bačáková, Radka (advisor) ; Pokorný, Jan (referee)
Title: Running in the context of developmental kinesiology Objective: The objective of this diploma thesis was to describe the running gait in the context of human developmental ontogenesis. From information sources working with the topic of developmental kinesiology, a comprehensive text was prepared on the influence of establishing posture on the subsequent development of locomotion patterns of walking and running. Methods: The compilation method was used in this work. Relevant peer-reviewed articles were drawn upon to identify current information on running kinesiology for subsequent interdisciplinary comparison of approaches to the definition and description of the running stride cycle. Results: In the thesis, it was repeatedly emphasized that reaching the float phase in a running gait is a genetically conditioned in a person's life. The thesis that the central control of postural-locomotor function is already engaged in the first year of life thanks to genetically encoded programs. In parallel with how the musculoskeletal system strengthens during the first year of life with the aim of overcoming gravity and achieving bipedality, the strength of functional control at the level of the CNS. Key words: step cycle of running, running, locomotion, posture, kinesiology of running
The relationship between body dimensions and locomotion in human and other hominins
Fedrová, Johana ; Struška, Michal (advisor) ; Vážná, Anna (referee)
We work with estimates of body weights and dimensions of hominins derived from fossil finds. The reliability of the estimate is important for calculations related to thermoregulation and energetics of the individual. The termoregulation of individual is influenced by number of factors including breathing type, sweating ability, body hair, type of locomotion, size of limbs to size of body ratio. Hair loss allows for greater heat loss. The ability to sweat and thermoregulate in hominins is more important for running than for walking. Heat loss is influenced by the trunk breath and the distal limb element lenght. Body shape in the current human population conforms to Allen's rule. Populations living closer to the equator show smaller bi-iliac width and longer limbs relative to body size. This trend can be observed in hominins. The cost of locomotion, the cost needed to travel a given distance in a given time, is affected by the lower limb lenght. Longer lower limbs reduce this cost, they allow to cover the distance using fewer steps. Each step is more costly because more muscle power is needed to move the longer limb. The step lenght and the optimal movement speed of the individual is proportional to the individual's stature. Man excels in the ability of bipedal locomotion, which Australopithecus...
Effect of ketamine on light-induced changes in the circadian system
Kratina, Alex ; Bendová, Zdeňka (advisor) ; Valeš, Karel (referee)
The circadian system is controlled by the suprachiasmatic nuclei of the hypothalamus (SCN) and ensures optimal timing of physiological processes. Synchronization of this system with external light conditions is based on the activation of NMDA receptors during light exposure in the subjective night. Ketamine is a non-competitive antagonist of NMDA receptors used as a safe anesthetic, whose subanesthetic doses act as an antidepressant with a rapid onset of action, and increase proliferation in some parts of the brain. There are hypotheses about the possible effect of subanesthetic doses of ketamine on the circadian system, altough this effect has not yet been tested. This work aims to investigate the effect of a single subanesthetic dose of ketamine on the circadian system of the rat, especially on light-induced changes in locomotor activity and light-induced markers in the SCN and dentate gyrus, which represents one of the strongly proliferative areas of the brain. Our results show that ketamine decreases light pulse-induced c-FOS protein expression in the SCN at the onset of the subjective night, but increases this expression in the dentate gyrus under the same conditions. Reduction of c-FOS expression in the SCN correlates with the behavioral output of the circadian system and thus suppresses the...

Performance measuring of individuals with physical handicap
Vít, Ondřej ; Kálal, Jan (advisor) ; Radvanský, Jiří (referee)
The thesis is focused on the measurement of the energy consumption during the locomotion of the mobility disabled (riding a wheelchair a walking with 2 point support - crutch). The probands were handicapped by partial amputation of lower limb based on the vascular cause which represents approximately 90 percent of all amputations done in the Czech Republic. The thesis also presents a brief classification of amputations according to the extent of the separation, the history of amputations and the main etiologic factors leading to amputation. In the result section the measured data are discussed. In the last part of the thesis, the conclusions are discussed and compared to information available from similar studies.

Metabolic costs of reproduction in vertebrates, particularly in reptiles
Kukačková, Dominika ; Kratochvíl, Lukáš (advisor) ; Hořák, David (referee)
Animal reproduction involves energy expenditures for gamete formation, support of offspring development, and associated behavioural changes. Due to high variability in reproductive traits, reptiles are the ideal study group for this field. Investment in reproductive organs and gametes represent costs of sex products production. The next phase of reproduction is gestation, when females support their developing offspring, which results in additional metabolic costs. Metabolism of pregnant female can be viewed as a sum of resting metabolism, which is the same as in non-pregnant animal, of increased metabolism to support pregnancy, and of embryonic metabolism. Separation of each component is crucial for assessing energy costs of reproduction and for comparison of different reproductive strategies. Certain behavioural changes during reproduction can influence total energy balance as well. These changes include increased locomotion costs or shifts in the thermoregulatory behaviour. Estimation of the real costs of reproduction is a complex matter since a reproduction is a very dynamic process and there are many issues that influence the overall energy consumption of reproducing individuals.
Physiological movements of the spine during locomotion
Dvořák, Jan ; Šafářová, Marcela (advisor) ; Špaňhelová, Šárka (referee)
Bibliographical record DVOŘÁK, J. Physiological movements of the spine during locomotion. Prague: Charles University, 2nd Faculty of Medicine, Department of Rehabilitation and Sports Medicine 2021. 75 p. Thesis supervisor PhDr. Marcela Šafářová, Ph.D. Abstract The diploma thesis Physiological movements of the spine during locomotion deals with the relationship between locomotion, spatiotemporal properties of gait and spinal movements. The theoretical part of the work summarizes the knowledge about the phylogenetic and ontogenetic development of the spine. The paper discusses the influences that affect the motility of the spine from intrauterine development to old age. The main part of the theoretical part is devoted to an overview of studies examining the movements of the spine during human locomotion. The experimental part was performed by testing a group of younger (24.6 ± 3.6 years) and older adults (43.5 ± 4.6 years). Both groups consisted of 8 women and 8 men. A total of 32 volunteers were tested. Otto's spine distance, thoracic spine rotation, 95% COP standing, and spatiotemporal gait data were measured using a Zebris Rehawalk FDM-T. Thereafter, therapy was applied to the chest to affect the dynamics of movement. Finally, control measurements of all olunteers were performed. Statistical data...
