The diploma thesis deals with the kinematic analysis of the most frequently used technique in sports karate. Specifically, it analyzes the technique of the direct punch Gjaku cuki from the perspective of kumite discipline. The thesis describes its theoretical implementation on the basis of professional publications dedicated to the general public as well as experts and points to the various factors that affect performance in kumite. The strike technique is analyzed in practice with various technical advances by using 3D kinematic analysis (SIMI Motion). The work analyzes in detail the movements of the individual segments of the body, the angular changes between them and examines the variables such as hull inclination, speed, acceleration, height and center of gravity track during the direct punch. The results are partially compared with the theoretical description and the differences in the results of the members of Czech national karate team with different technical maturity are examined. The conclusion are summarized the acquired knowledge from kinematic analysis, which provide a recommendation for the training practice and appropriate advice on quality of Gjaku cuki.

The thesis "Judging the influence of constitutional hypermobility on postural stability" focuses on the problem of constitutional hypermobility (CH) and the influence of joint instability on stability mechanisms. The aim of the research was to find out whether there is a difference in stability mechanisms with tested subjects with CH and without it. Furthermore, the research focuses on the influence of mobility techniques on postural stability by the means of chosen tests carried out on Balance Master® System platform. The tested sample includes 14 women aged from 20 to 28, 7 women with constitutional hypermobility and 7 women as a control group. 6 tests were chosen for the measurement on Balance Master® platform. 2 static tests: modified Clinical Test of Sensory Interaction on Balance (mCTSIB), Unilateral Stance (US), and 4 dynamic tests: Limits of Stability (LOS), Rhytmic weight shift (RWS), Step Up Over (SUO) a Forward Lunge (FL). We compared the medians of output values of individual tests. It was assumed that subjects with KH would have significantly worse test results than the control group. Furthermore, it was supposed that the mobilization processes cause stability disturbance on the basis of cancellation of compensational , thus protective block in comparison with KS.

[pt] Com o aumento da popularidade e acessibilidade de sistemas de realidade virtual (RV) de alta qualidade, tem-se levantado preocupações com relação a tendência dos sistemas de realidade virtual em provocar perda de equilíbrio. O equilíbrio é essencial para o uso seguro da realidade virtual e a perda do mesmo pode causar lesões graves. O objetivo deste trabalho é criar um sistema para avaliar o impacto da realidade virtual no equilíbrio humano. Neste trabalho, propomos e conduzimos um experimento usando o Oculus Rift e o MS Kinect Sensor. Nesse experimento, foi possível observar, quantificar e comparar o efeito de diferentes cenas de RV no equilíbrio dos usuários, bem como o efeito de avisos visuais e sonoros sobre perda de equilíbrio. / [en] With the increasing popularity and accessibility of high-quality Virtual Reality (VR) systems, concerns have been raised about the propensity of VR to induce balance loss. Balance is essential for safe use of VR experience and its loss can result in severe injury. This project is set to create a system able to measure the impact of VR in the human balance system. In this work, we design and conduct an experiment making use of the Oculus Rift VR headset and MS Kinect Sensor. In this experiment, we are able to visualize, quantify, and compare the effect of different VR scenes on the balance of the experiment subjects as well as the effect of visual and auditory warnings of balance loss.

Weight analysis includes determining center of gravity according to longitudinal static stability margin. The drag polar of the airplane is determine for cruising regime of flight, that means the regime of following an airliner.

According to NATO Review, in 2013 it was estimated that over 97% of the world's telecommunications were transmitted via the internet and that this was a growing trend. This essentiality for communication means that information systems have become a natural target and point of attack in military actions and planning. This thesis aims to test the possibility to apply the theory of The enemy as a system and the concentric five-ring modeldeveloped by air force theorist Jon A. Warden III, to the cyber arena. To achieve this aim, the thesis presents a qualitative text analysis of seven different sources describing NotPetya. The targets and effects of the cyber attack are evaluated based upon the concentric five-ring model and the concept of parallel attack. The results of the analysis shows that Warden's theory is highly applicable to the case of NotPetya. This in turn could point to the theory’s applicability to the cyber domain and to strategic operations in cyberspace. However no major conclusions of generalizability can be drawn.

.../... / “Standards make a positive contribution to the world we live in. They facilitate trade, spreadknowledge, disseminate innovative advances in technology, and share good management andconformity assessment practices”7. There are a multitude of standard and standard consortiaorganizations producing market relevant standards, specifications, and technical reports in thedomain of Information Communication Technology (ICT). With the number of ICT relatedstandards and specifications numbering in the thousands, it is not readily apparent to users howthese standards inter-relate to form the basis of technical interoperability. There is a need todevelop and document a process to identify how standards inter-relate to form a basis ofinteroperability in multiple contexts; at a general horizontal technology level that covers alldomains, and within specific vertical technology domains and sub-domains. By analyzing whichstandards inter-relate through normative referencing, key standards can be identified as technicalcenters of gravity, allowing identification of specific standards that are required for thesuccessful implementation of standards that normatively reference them, and form a basis forinteroperability across horizontal and vertical technology domains. This Thesis focuses on defining a methodology to analyze ICT standards to identifynormatively referenced standards that form technical centers of gravity utilizing Data Mining(DM) and Social Network Analysis (SNA) graph technologies as a basis of analysis. As a proofof concept, the methodology focuses on the published International Standards (IS) published bythe International Organization of Standards/International Electrotechnical Committee; JointTechnical Committee 1, Sub-committee 36 Learning Education, and Training (ISO/IEC JTC1 SC36). The process is designed to be scalable for larger document sets within ISO/IEC JTC1 that covers all JTC1 Sub-Committees, and possibly other Standard Development Organizations(SDOs).Chapter 1 provides a review of literature of previous standard analysis projects and analysisof components used in this Thesis, such as data mining and graph theory. Identification of adataset for testing the developed methodology containing published International Standardsneeded for analysis and form specific technology domains and sub-domains is the focus ofChapter 2. Chapter 3 describes the specific methodology developed to analyze publishedInternational Standards documents, and to create and analyze the graphs to identify technicalcenters of gravity. Chapter 4 presents analysis of data which identifies technical center of gravitystandards for ICT learning, education, and training standards produced in ISO/IEC JTC1 SC 36.Conclusions of the analysis are contained in Chapter 5. Recommendations for further researchusing the output of the developed methodology are contained in Chapter 6.

Title: Evaluation criteria in running techniques in younger school age Objectives: The aim of this work is to perform the evaluation criteria in running technique in younger janitor age. In selected children I observed their technique of running in individual criteria. From the obtained data we will further find out how and in what the selected children improved. We will observe and assess individual criteria that will help us to the overall technique in the run. Methods: The experimental method of observation and measurement under artificially induced conditions was used. Results: I have found that children of younger school age can be significantly improved in the running technique for two months. In this period, children have great potential to learn new movements. I think that repeated specific running exercises help to improve the technique in running. Keywords: reflection, running step, vertical and horizontal movement of center of gravity, movement of upper limbs
