Dynamic Scene Model for Mobile Robot
Görig, Jan ; Štancl, Vít (referee) ; Španěl, Michal (advisor)
This master's thesis focuses on representation of geometric information about the surrounding environment for robotic systems. Instead of a common point-cloud based representation, an environment model that stores information about objects described by bounding boxes and planes is proposed. These objects can be obtained from trained object detectors, planar surface detectors, etc. processing data from sensors (e.g. RGB-D camera). The information about the objects (position, etc.) stored in the model is constantly changing according to data obtained from detectors. The environment model is implemented as a module for Robot Operating System. To illustrate and visualize features of the model, a demonstration application was also prepared.

Hanko, Michal ; Bunc, Václav (advisor) ; Suchý, Jiří (referee)
Title: Influence of acute stretching on strength predispositions in snowboardcross Objectives: The aim of the work is to evaluate two effects of stretching - static and dynamic on the strength assumptions of the lower extremities by modifying the Bosco test in a group of 3 athletes in the snowboardcross discipline. Methods: Power Measurement in Bosco's Test Modification (3 series jumps of 20 seconds with a 20-second pause) after 5 minutes of warm-up on the bike ergometer (1.5W/kg) and application of a predetermined static or dynamic stretch (approximately 14 minutes). The probands are 3 male athletes in the snowboardcross discipline, aged from 16 to 23 years. Their fitness training consists of a gym 3 times a week (60-90min), gymnastics twice a week (90 min) and an individual evening stretching to develop flexibility at least 3 times a week (30 min). In the off-season, athletic training once a week (60 min). Measured values are - jump count, flight phase time in seconds, contact phase time in seconds, average power expressed in watts, and power drop in percent. Results: We found that two types of stretching - dynamic and static - have different effects on performance in the Bosco test modification. Significantly better results were achieved after application of dynamic stretching. In average...

Analysis and design of a system for the support of distant management staff
Šatánek, Josef ; Oškrdal, Václav (advisor) ; Poštulka, Petr (referee)
The main objective of this thesis is to make an analysis and to design of a system for the support of distant management staff. An emphasis is placed upon the system design for effective utilization in practice and openness for further development. The theoretical part is divided into three main chapters. The first chapter is about describing the issues of process and project management in terms of the focus of this thesis. The output of this chapter is a list of the general requirements of the system for the support of distant management staff. In the second chapter is an analysis of the market with systems that best meet the defined general requirements. The third chapter is about describing the methods which are used in the practical part of this thesis. The practical part is mainly about realizing the main objective of this thesis. The practical part is divided into three main chapters. The first chapter contains a catalog of requirements for the system for support remote management staff. The second chapter is describing the design of the requirements defined in the first chapter of practical part.

The Influence of Dynamic Stretching to the Immediate Enforcement
SVOBODA, Vojtěch
The work is focused on the evaluation of the impact of two types of stretching on subsequent performance. With regard to the content can be divided into practical and theoretical. A practical part brings relevant knowledge to solve problems. Attention is given to the anatomy of the muscle fiber, the physiology of muscle contraction and muscle connections with the central nervous system. The study also describes the proprioceptive function of muscles, the anatomical dimensions and principles of operation. In connection with the internal control possibilities stretching the muscles are in the theoretical part also describes the reflexes at the level of the muscle fiber. General principles of stretching can be found in this section too. The following is a detailed resolution types of stretching and their implementation, advantages and disadvantages. At the end of the theoretical part describes general contraindications stretching and hypermobility as one of the risk factors. The second part belonged to practical research. The research aims to answer the question: "Which type of stretching before exercise has a better effect on the actual performance?" For this purpose we selected eight active athletes. After showing of concrete stretching workouts were tested person familiar with the disciplines in which the effect of stretching measured. It was a 40 yard sprint, a specific form of the shuttle run, jump from a place in the distance and the implementation of push-ups without stopping to find the maximum number of times. These disciplines have been always performed after the application of one type of stretching, with a minimum range of measurement was determined at 24 hours, for reasons of objectivity research. Overall, each activity was measured four times - twice after the static and twice after the dynamic stretching. Research records the individual variations in the measured values after the static and dynamic stretching in all tests. For better clarity, the deviations from the established arithmetic averages referring to the average positive and negative deviations. The resulting values are then captured in tables, graphically and verbally explained. All the four measurements showed analogous results. In the first three disciplines is a better determination of the dynamic type of stretching due to the relatively higher performance of individual activities. For Sprint and the shuttle run times were recorded less necessary to overcome the distance. At the same time was also significantly better in negative average deviation of the measured times after dynamic stretching. The last tested motion became workout pushups without rest for the maximum number of repetitions achieved. Based on this research it is not possible to determine the appropriate method of preparation for discipline. Implementation of push ups assigns power-endurance nature. Due to the relatively clear results for the other, short-term activities associated with the maximum of performance, it seems clear that the type of stretching manifests a greater impact with this type of load compared to strength-endurance exercise in the form of push-ups. Chapter titled "Discussion" is again divided into two parts. In the first analysis is made of the results and conclusions with regard to possible opposition view on objectivity of measurement. Research is generally considered as the objective and the results are accorded legitimacy. In the second part of the discussion are the conclusions obtained subject to comparison with other international studies that have looked at the impact of these types of stretching at the same or a similar discipline. Given the above facts and research itself can be considered for answering the research question. Short-term disciplines carried out with maximum intensity can be demonstrated dynamic stretching before the actual performance for better compared to static stretching.
