In Proc. of IEEE Int’l Conf. on Computer Vision, Vancouver, Canada, 2001 Vision-based motion capturing of hand articulation is a challenging task, since the hand presents a motion of high degrees of freedom. Model-based approaches could be taken to approach this problem by searching in a high dimensional hand state space, and matching projections of a hand model and image observations. However,...

BACKGROUND The use of larger femoral heads has been proposed to reduce the risk of dislocation after total hip arthroplasty, but there is a lack of evidence to support this proposal. The aim of this multicenter randomized controlled trial was to determine whether the incidence of dislocation one year after total hip arthroplasty is significantly lower in association with the use of a 36-mm femo...

The focus of this thesis is the relationship between the articulation of speech and the acoustics of produced speech. There are several problems that are encountered in understanding this relationship, given the non-linearity, variance and non-uniqueness in the mapping, as well as the differences that exist in the size and shape of the articulators, and consequently the acoustics, for different...

1. Introduction Human speech production requires a complex coordination of motor control for respiration, vocalization, and articulation. The neural mechanisms for speaking have been studied since the 17th century, yet many questions remain in determining the brain regions involved in speech production. In evidence of this, recent functional brain imaging studies examining normal subjects' arti...

The relationship between diadochokinetic rates and the degree of articulation impairment, measured as number of articulation errors on a test, was investigated. Sixand eight-year old children with articulation impairment demonstrated reduced diadochokinetic rates which appeared to improve with age. The larger the number of articulation errors, the slower the rates on both verbal and non-verbal ...
