This thesis focuses on history of the artificial slalom track in Český Vrbný near České Budějovice. After a complex reconstruction and revitalization, which took place in the years 2009 - 2012, the Lída Polesná water sports complex is a top artificial slalom trail, belonging among the three best in the Czech Republic. Moreiver it is a real and very popular sporting, recreational and training center not only of regional but also of national importance. This thesis contains history of the slalom track moreover also includes an outline of the history of canoeing in the Czech lands until the first artificial slalom trails. Furthermore it includes an outline of the history of the Česke Budejovice canoeing, an outline of the history of the weir in Český Vrbný and comparison of this track with other similar facilities. It also includes an overview of artificial slalom trails in the Czech Republic and Slovakia and is further supported by an overview of their parameters and their photographs. The thesis is a 100 page-wide. The thesis has 75 attached pictures with labels. The main format msily consist of two original photographs, pictures, maps, or drawings.

This master’s thesis deals with driving maneuvers at low coefficient of adhesion, especially in winter season. It includes a list of adhesion coefficients on many surfaces, published by various authors. Figures were through the use of statistical methods divided into normal and exceeding. There are described terms having impact on adhesion. For determination of adhesion was used tests like emergency braking, circle test and slalom. The major part contains specification of used vehicles, surfaces, weather conditions, measuring devices and realized tests. In addition to using accelerometer, there was a successful attempt to use timekeeping facilities to determine deceleration of vehicle. Acquired data were processed and compared to another publications.

Title: Summer training of downhill skiers using nontraditional sport disciplines Objectives: The main goal of this diploma thesis is based on the results of a survey to verify whether the selected nontraditional sport disciplines are used in the annual training cycle of downhill skiers. Based on the ascertained information then to process methodical materials of each from nontraditional sport disciplines and characterize them in detail. Methods: There were used methods of content analysis and synthesis of scientific text. It was mainly book titles and internet resources. To verify the technical issues a quantitative research was used. For collecting the necessary data a method of public inquiry in electronic form with subsequent processing and evaluation was used. The questionnaire contained 15 uniquely formulated questions. The first four questions were of sociodemographic type to obtain further identification of the respondents (gender, age, education, region), the remaining 12 questions were directed to approach the issue of summer training of downhill skiers, its duration and financial cost. Results: Based on the survey it was found that the competitors have at least one of the nontraditional sport discipline included in their summer training for the winter season. It was mainly in-line alpine...

An urban operation of unmanned aerial vehicles (UAVs) demands a high level of autonomy for tasks presented in a cluttered environment. While fixed-wing UAVs are well suited for long-endurance missions at a high altitude, enabling them to navigate inside an urban area brings another level of challenges. Their inability to hover and low agility in motion cause more difficulties on finding a feasible path to move safely in a compact region, and the limited payload allows only low-grade sensors for state estimation and control. We address the problem of achieving vision-based autonomous navigation for a small fixed-wing in an urban area with contributions to the following several key topics. Firstly, for robust attitude estimation during dynamic maneuvering, we take advantage of the line regularity in an urban scene, which features vertical and horizontal edges of man-made structures. The sensor fusion with gravity-related line segments and gyroscopes in a Kalman filter can provide driftless and realtime attitude for ight stabilization. Secondly, as a prerequisite to sensor fusion, we present a convenient self-calibration scheme based on the factorization method. Natural references such as gravity, vertical edges, and distant scene points, available in urban fields, are sufficient to find intrinsic and extrinsic parameters of inertial and vision sensors. Lastly, to generate a dynamically feasible motion plan, we propose a discrete planning method that encodes a path into interconnections of finite trim states, which allow a significant dimension reduction of a search space and result in naturally implementable paths integrated with ight controllers. The most probable path to reach a target is computed by the Markov Decision Process with motion uncertainty due to wind, and a minimum target observation time is imposed on the final motion plan to consider a camera's limited field-of-view. In this thesis, the effectiveness of our vision-based navigation system is demonstrated by what we call an "air slalom" task in which the UAV must autonomously search and localize multiple gates, and pass through them sequentially. Experiment results with a 1m wing-span airplane show essential navigation capabilities demanded in urban operations such as maneuvering passageways between buildings.
