A cost-effective method for ultrasound volumetric imaging
(1996)
A synthetic receive aperture technique is explored for cost-effective ultrasound scanners with high frame rates and beam density. The technique provides ultrasound volumetric imaging where beam count is very large with 2-D ...
Segmentation of ultrasonic images using fuzzy sets
(1996)
An image segmentation technique based on fuzzy sets for ultrasonic B-scans is presented. The fuzzy c-means algorithm is adapted to B-scan images. The classes constituting a region are obtained through fuzzy partitioning ...
In-vitro studies of enteric coated diclofenac sodium-carboxymethylcellulose microspheres
(Taylor & Francis Ltd, 1996)
Microspheres containing diclofenac sodium (DS) were prepared using carboxymethylcellulose (CMC) as the main support material (1.0, 2.0, 3.0% (w/v)) and aluminium chloride as the crosslinker. Drug to polymer ratios of 1:1, ...
Comparison of β-galactosidase immobilization by entrapment in and adsorption on poly(2-hydroxyethylmethacrylate) membranes
(Royal Swedish Acad Sciences, 1996)
Schottky barrier height shifts depending on the interfacial layer as well as a change of the interface state charge with the forward bias while considering the presence of bulk (semiconductor) series resistance are discussed ...
Kinetic study of ligand exchange reaction of anions as ligands on DAE-sporopollenin
(Academic Press Inc Jnl-Comp Subscriptions, 1996)
The specific rate coefficients and ligand sorption isotherms of Br and I- as ligands on diaminoethyl-sporopollenin were determined as a function of pH and temperature between 20 and 60 degrees C. The ligand exchange rates ...
Numerical and experimental stress analysis of a polymeric composite hip joint prosthesis
(John Wiley & Sons Inc, 1996)
A comparative stress analysis of a polymeric composite hip joint replacement was performed. A prototype short carbon-fiber reinforced PEEK (CF/PEEK) prosthesis was manufactured by injection molding. Finite element (FE) ...
Application of the dynamic stiffness technique to the in-plane vibrations of plate structures
(Pergamon-Elsevier Science Ltd, 1996)
In this study the dynamic stiffness technique, which yields ''exact'' results for a certain class of plate structure, is extended to include in-plane vibrations. Using the equations of motion and edge tractions the stiffness ...
