Participation in children’s and youth sports is increasingly popular and widespread in western culture. In the USA, for example, more than 30 million children participate in sports each year. Trends over recent decades include increased numbers of participants, particularly girls, increased duration and intensity of training, earlier specialisation and year-round training, and increased difficu...

A friend and I were discussing this. We both try to stay healthy by eating well (high fiber, low fat, lots of veggies, fruit, etc.) and living an active enough lifestyle (hiking, rock climbing, biking, etc.) that we stay in shape. The question we have, then, is what the current "rules" are for appropriate weight/height ratios? Or are such measurements now thrown out in favor of body fat percent...

People vary in their appetite for risk. Some people’s idea of fun is paragliding or rock climbing, whereas I’d opt a gentle jog followed by good book. In my spare time I can enjoy the luxury control over how much risk take, and although may sometimes feel anxious about choices others, generally support right to choose. That degree doesn’t extend all spheres our lives, where we often depend on ...

The British Sola Khumbu Expedition of 1959, led by Mr. J. H. Emlyn Jones, had as its objective the ascent ofAma'Dablam, an unclimbed Himalayan peak 22,400 ft. high, lying some ten miles south of Mount Everest. Secondary objectives of the expedition were to investigate the changes in the heart as shown by the electrocardiogram produced by climbing at high altitude, which is the subject of this p...

In this paper, we propose a new method based on Hidden Markov Models to interpret temporal sequences of sensor data from mobile robots to automatically detect features. Hidden Markov Models have been used for a long time in pattern recognition, especially in speech recognition. Their main advantages over other methods (such as neural networks) are their ability to model noisy temporal signals o...
