Title: Personality typology of participants in survival races using psychodiagnostic method GPOP (Golden Profiler of Personality) Goals: Our main goal was to determine personality typology of participants in survival, specifically in Adventure racing to compare the results obtained by AR athletes with Czech standards. Method: There were used method of GPOP (Golden Profiler of Personality) in diploma thesis. This method follows a well - known method MBTI (Meyer - Briggs Type Indicator). However, compared to MBTI method GPOP is standardized in Czech Republic. GPOP consist of four paired scales and compared to MBTI it has also the scale which focuses on the stress reaction. GPOP is based on survey of 116 questions and statements. Final results show which of two pair scales is preferred by participants. Every paired scale has its own five subscales. GPOP presents us 16 types of personality overall based on mentioned paired scales and subscales. We also created secondary non - standardized survey which regards athletes participation in Adventure races and survivals, so we would confirm their inclusion to research group. Results: In the population of athletes who participate in survivals (AR) there shows significant representation personality type ISTJ and ESTJ (47,6 % in comparison with other...

O presente estudo tem como objetivo identificar como ocorreu o processo histórico da prática do automobilismo de rua em Porto Alegre, no período de 1926 a 1956. A pesquisa foi sustentada em fontes impressas e orais, bem como na apresentação de fotografias disponibilizadas pelo acervo do Museu Brasileiro do Automobilismo, localizado na cidade de Passo Fundo, Rio Grande do Sul. Os resultados obtidos demonstram que o automobilismo de rua contribuiu para construir uma representação de modernidade, a partir do cenário esportivo, delineado em Porto Alegre. Esta prática teve seu início em meados da década de 1920, registrando a realização de um grande número de provas automobilísticas, na década de 1930, com a criação da segunda equipe de competição do Brasil, a Escuderia Galgos Brancos. Os gaúchos sofreram influência, nos traçados das provas e nos modelos de carro – as carreteras - dos países vizinhos Uruguai e Argentina, não só técnico, mas de pilotagem. No período de 1950, o Rio Grande do Sul torna-se polo do automobilismo nacional, com o maior número de provas realizadas e destaque para os pilotos gaúchos nas provas automobilísticas. O automobilismo estimulou a indústria nacional automobilística e de autopeças, estabelecendo em seus regulamentos a obrigatoriedade dos competidores usarem, em seus carros, componentes de fabricação nacional. Por fim, evidenciou-se que, no período estudado, o automobilismo estava inserido no imaginário dos gaúchos como uma prática de modernidade, paixão e vitórias dos ases do volante. / This study aims to identify how the historical process of street racing took place in Porto Alegre, from l926 to l956. The research is supported in printed and oral sources as well as in the display of photographs provided by the Brazilian Automotive Museum, located in the city of Passo Fundo, Rio Grande do Sul, a southern state of Brazil. The results achieved demonstrate that street racing has contributed to build a representation of modernity departing from the sports setting outlined in Porto Alegre. This practice began in the mid-l920 decade and, in the 1930 decade, a large number of motor racing was recorded due to the creation of a second competition team in Brazil, the White Greyhounds racing cars owners pool – Escuderia Galgos Brancos. The so-called gaúchos – people from the southern state of Brazil – have been influenced on competition layout and car models – carreteras – by Uruguai and Argentina, neighboring countries, not only in technical, but also in piloting aspects. In the 1950 decade, Rio Grande do Sul became the main center of Brazilian motor sport because it was the state where the largest number of car competitions took place and also because of the oustandingly performances of the southern pilots in them. Car racing has stimulated the national motoring and auto parts industry by establishing in its regulation a basic requisite: the competitors had to use components, manufactured in Brazil, in their cars. Finally it became evident that during the period that has been studied car racing was inserted into the imagination of the gaúchos as a practice of modernity, passion and victories of the the steering wheel aces.

Grinding set-up in America's Cup sailing provides the power behind tacking and gybing, where the yacht crosses the wind to change direction. Grinding is also used for trimming the sails, which changes the angle on which the yacht is headed. This study provided a descriptive biomechanical overview of grinding on an America's Cup class yacht, and experimentally evaluated the influence of technique instruction on backward grinding performance. Inter-subject differences in body position (technique) throughout the grinding cycle, the ability to alter grinding technique within an eight-day technique intervention period, and the effect of technique on grinding performance as determined by power output were assessed. The quasi-experimental design, in which each of eleven Team New Zealand America's Cup grinders served as their own control, assessed four trials of backward grinding at baseline and post-biomechanical technique intervention testing sessions. Each trial was a maximal effort performed against a high load (250 W) and sustained over a period of eight seconds. Sagittal plane video was used to analyse joint kinematics (elbow, shoulder, trunk, hip, knee, ankle angles and joint centre positions) and to calculate the centre of body mass relative to the grinder pedestal. Height, weight, and limb lengths were obtained from each grinder using the ISAK protocol. Current backward grinding technique employed by the majority of grinders did not optimally use biomechanical principles. Recommendations for improvement were specific to each individual but focused on lowering trunk position and distancing the trunk from the grinding pedestal. Real-time visual feedback was provided to the grinder operators with the main focus being the position of their hip joint (viewed in the sagittal plane), and lowering the shoulder to be vertically level with the apex of the grinding handle cycle. During the intervention the grinders were given added correctional instruction relating to their body position according to perceived technique requirements. Recommendations were based on biomechanical principles regarding body position, and how body position could be altered to optimise the contribution of body weight and force production by the muscles of the upper limb in order to improve the torque applied to the handles. Altering grinding technique according to biomechanical principles produced 4.7% (p = 0.012) greater power during five seconds of grinding performance. Muscular strength, when measured using a 1RM bench pull (116.4 ± 9.8 to 117.3 ± 10.3), was unaffected by the intervention program, thus not contributing to the increased power output observed during grinding. Moderate changes to body position were observed after the eight-day intervention. Forward lean of the trunk decreased from 25° to 17° (p = 0.028) due to a lower hipy position (-0.09 m to -0.16 m below hub, p = 0.019). The more vertical trunk alignment resulted in the shoulderx position being further from the hub (0.33 m to 0.41 m, p = 0.013), producing a greater line of pull due to a more efficient shoulder vector angle (47° to 36°, p = 0.009). Variability (standard deviation and confidence intervals) decreased in all but four kinematic measures (which exhibited no change) indicating improved consistency in grinding technique. Regression analysis indicated the best predictors for high-load backward grinding performance were COMx position relative to the grinding pedestal and maximal strength. Changes in COMx position explained 40% (p = 0.166) of the variation in grinding performance, while maximal strength showed a relationship of 0.23% (p = 0.144) increase in performance per kilogram of bench pull 1RM. A one standard deviation difference in maximal strength altered the effect of COMx position by 0.26% per centimetre (p = 0.008). Weaker predictive factors were body weight, standing height, and pull angle, while brachial index did not appear to have any substantial influence on backward grinding performance. For future research greater subject numbers should enable more conclusive findings, especially in terms of the technique mechanisms and their relative levels of influence on performance.

An inverted wing with various endplate configurations was investigated at two different angles of incidence. A moving ground was designed and constructed for use in the UNSW T1 wind tunnel. The test cases were investigated in ground effect using the moving ground. Measurements and observations were obtained using laser sheet flow visualisation and laser doppler anemometry. Computational fluid dynamics models of the test cases were run to gain further understanding of the flow field generated when using inverted wings with endplates. The computational fluid dynamics models correlated well to the experimental results.

<p>Vobbla Racing is a racing team who has an online sales department that is in need of an upgrade to be more efficient and easier to use. Before this study their present homepage was anything but structured. The products were sorted in an illogical order which made it difficult for the customer to find a wanted product. The customer had to summarize the products, transport sums and other costs. The order had to be e-mailed or phoned in to Vobbla Racing Produkter. As new products arrived to the assortment a structured control of the warehouse was difficult to achieve. By creating a web shop and an online inventory system it will be more efficient and easier to use both for employee and costumer. An administrator shall by an administrator site handle the product-, order-, and menu information. The customer shall easily navigate through the product pages and add wanted products to the shopping cart. The customer shall also be able to register as a member of Vobbla Racing Produkter to easier place an order and to get information such as previous orders. We made an analysis of Vobbla Racing\2019s present sales procedure and their wanted situation which showed areas in their activities that were in need of efficiency. A survey was made for us to get a brief overview of how a web shop is build. It helped us to get an understanding in our planning of the web structure. The web shop is build with ASP that works against a database to get and store information. The products in the shopping cart are stored in a cookie so that the database and web shop doesn't get overloaded. The shopping cart is always available for the customer to give an overview of his products. Vobbla Racing Produkter is happy with the result. We created the critical parts for the shopping and inventory, but not everything we had hoped for.</p>

Several standardized courses for Formula SAE (FSAE) testing are introduced and described with sufficient detail to be reproduced by any Formula SAE team. Basic analysis methods for the courses are given as well as explanations of how those analyses could be used. On-car data from the Global Formula Racing (GFR) SAE cars is used to verify the analysis methods, give estimates to unknown variables, and show the relevance of the standard testing courses. Using the courses and methods described in this paper should allow standardized comparison of FSAE car performance, as well as provide a method to verify simulations and evaluate changes in vehicle performance from tuning. Instrumentation of all suspension member forces with strain gauge load cells is shown to be an extremely powerful tool for measuring vehicle performance and quantifying vehicle dynamic characteristics. The design and implementation of strain gauge load cells is described in detail to provide a template for reproducing similar results in other vehicles. Data from the GFR 2011 FSAE car is used throughout the paper to: show the design process for making effective suspension member load cells, show the calibration processes necessary to ensure quality data is collected, illustrate the calculation of suspension corner forces, and show the effectiveness of measuring vehicle dynamic characteristics with this technique. Using the methods described in this paper should provide data that allows a more complete and thorough understanding of on-car vehicle dynamics. This data may be used to validate vehicle models. / Graduation date: 2012

<p>In racing, it is useful to analyze vehicle performance and driving strategies to achieve the best result possible in competitions. This is often done by simulations and test driving.</p><p>In this thesis optimal control is used to examine how a racing car should be driven to minimize the lap time. This is achieved by calculating the optimal racing line at various tracks. The tracks can have arbitrary layout and consist of corners with non-constant radius. The road can have variable width. A four wheel vehicle model with lateral and longitudinal weight transfer is used.</p><p>To increase the performance of the optimization algorithm, a set of additional techniques are used. The most important one is to divide tracks into smaller overlapping segments and find the optimal line for each segment independently. This turned out to be useful when the track is long.</p><p>The optimal racing line is found for various tracks and cars. The solutions have several similarities to real driving techniques. The result is presented as driving instructions in Racer, a car simulator.</p>
