This paper presents a computerized method for the selection of an irregular region of interest (ROI) in broadband ultrasound attenuation (BUA) images. A region growing algorithm searches an initial region in the posterior part of the calcaneus until the pixel with the lowest attenuation value is found; this is the starting seed. Then, the algorithm(More)
In this paper some experience of using a new least squares, finite element method for solving Stokes flow in two dimensions based on approximating the derivative of stress and stream functions is reported. This work gives rise to serious concerns about the lack of mass conservation in the least squares approach to solving fluids problems both in the method(More)
