Some physical properties and chemical compositions of two cultivars (Semsouri and Shahabadi) of cantaloupe studied during four different stages of maturity from fruit set to completely ripe. The physical properties investigated were the geometric mean diameter (GMD), specific gravity (SG), mean firmness (MF), rind, seed (%) and flesh (%). The chemical compositions were Brix, Titrable Acidity (T...

OBJECTIVE To study the correlation between peak wall stress (PWS) and abdominal aorta aneurysm (AAA) geometric parameters in the presence of intraluminal thrombus (ILT). DESIGN Computational study using finite element analysis. MATERIAL AAA models were created by three-dimensional (3D) reconstruction of in vivo acquired computed tomography (CT) images from 19 patients. METHODS PWS was eva...

An automatic algorithm capable of segmenting the whole vessel tree and calculate vessel diameter and orientation in a digital ophthalmologic image is presented in this work. The algorithm is based on a parametric model of a vessel that can assume arbitrarily complex shape and a simple measure of match that quantifies how well the vessel model matches a given angiographic image. An automatic ves...
