A study of ground effect performance is presented with specific applications to Gamera, a human powered helicopter. This parametric study quantifies ground effect for four different rotors: a baseline (no twist/no taper), negative twist/no taper, positive twist/no taper, and taper/no twist. Data for these four rotors are presented in power polars and as(More)
Previous computerized methods of hyperintensity identification in brain magnetic resonance images (MRI) either rely heavily on human intervention or on simple thresholding techniques. Such methods can lead to considerable variation in the quantification of brain hyperintensities depending upon image parameters such as contrast. This paper describes an(More)
The clinical significance of micturition investigations is to be seen not only in the quantification of urethral obstructions e.g. after operations for stress incontinence. Such measurements in fact give information on very different forms of voiding dysfunctions with and without morphological substrates. Simultaneous EMG measurements permit further(More)
