<p>Did the right person win? In competitive sports the difference between winning and loosing can be very marginal but still the result will have a big impact. To finish second, even if it is an Olympic Game, can be felt like a failure for the athlete. In the light of this the quality of the measurements and the judgements in sports are an extremely important issue. In this dissertation, consisting of two separate reports and one summary report, the freestyle discipline, acroski, and the gymnastic discipline, rhythmic gymnastics (RG) where studied with a focus on the rules and judgements in the sports. The reliability and validity of the rule and judging systems were analysed together with changes in the rule and judging systems. The reliability, as the judges ability to interpret the rules and judge in a consistent way, and validity in the sense that the judgements, and the rules for the judgements, where in accordance with the idea of the sport. Information was gathered from rulebooks, judging manuals, meeting protocols, and historical documents. For information on how the rules and judgements where perceived among people involved in the two sports, interviews where carried out with two coaches, two judges and four athletes from each of the sports. In the summary report the results from the two reports where discussed and a comparison of the rule systems and judgements was made together with a discussion about reliability and validity problems in sports measured by time, length and height. The results showed that the rule and judging systems in acroski and RG in a short time have gone through major changes to increase the reliability and validity in the judgements. The quick evolution of these sports seems to be the main reason for these changes but also other factors where of vital importance. Finding the balance between making the judgements as objective as possible, without loosing the idea of the sport, together with the quick evolution of the sports, seemed to be the main challenges in the rule and judging systems of acroski and RG.</p>

The purpose of Morphology is to capture features and attributes of image, such as boundaries and contours. It has been widely applied to computer vision, the analysis and processing of image and even industry examinations and medical image processing. The reason why the Morphology is widely applied is that we can use its simple structure elements to process images, and get up to our requirements. Therefore, it¡¦s become our primary study to find out those suitable structure elements. In this paper, we used the laws of judging the multiple mask relationship to find out filters which came up to the condition that we set, and also came up with an efficient way to find out filters that we want to get.

This research compared physical characteristics of bodybuilders to judges' rankings, and compared the judges' rankings across three levels of judges: Elite, Trained, and Untrained. Twenty-nine male and nine female bodybuilding athletes consented to anthropometric and circumference measurements. The independent variables in this study were bodyfat, fat-free weight, and proportionality of muscle. Three groups of judges ranked male and female athletes in the Open, Novice, Collegiate, and Masters divisions. The measurements of proportionality of muscle, bodyfat, girths, and fat-free weight were analyzed using simple and multiple regression. The judges' rankings in each class were compared using reliability coefficients, correlation, repeated measures analysis of variance, and the generalized theory for inter-rater reliability. There were significant correlations between the Elite judges' rankings and bodyfat in the Men's Open lightweight class. The Trained and Elite judges' rankings were significantly correlated with bodyfat in the Women's Novice class. Fat-free weight was significantly correlated with the Untrained and Elite judges' rankings in the Women's Novice division. Proportionality of muscle was significantly correlated with the Elite and Trained judges' rankings in the Men's Open lightweight class. Elite and Trained judges' rankings were significantly correlated with bodyfat and proportionality of muscle. All three groups of judges' were significantly correlated with the Overall rankings. The Trained judges' rankings were more correlated and more reliable with the Elite judges. The inter-rater reliability scores were higher for the Elite and Trained judges than for the Untrained judges. When fat-free weight was substituted for body weight in the calculation of proportionality of muscle, prediction of ranking was enhanced. The education session led to a significant disparity in judges' rankings between Trained and Untrained judges. Bodyfat appears to be a better selection variable when comparing physical measurements to judges' rankings in women. Proportionality of muscle is a better selection variable in predicting judges' rankings in men. Prediction models developed from this investigation need further testing. / Ph. D.
