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 ...
An IBM(2) investigation of some properties of 100Ru nuclei
(1997)
In this study, energy values, B(E2) values and quadrupole moment of {100}Ru isotope at the onset of the deformed region were investigated by using the Interacting Boson Model (IBM-2). The results were compared with the ...
The effect of exposure time to clean room air on characteristic parameters of Au/Epilayer n-Si Schottky diodes
(1998)
A study has been made on determination and comparison of current-voltage (I-V) and capacitance-voltage (C-V) characteristics parameters of Au/n-Si Schottky barrier diodes (SBDs) with and without thin native oxide layer ...
Controlled release of Aldicarb from carboxymethylcellulese microcapsules
(1997)
Sodium carboxymethyl cellulose was converted into microspheres by crosslinking with aluminum chloride. Various microsheres with different amounts of crosslinker, biopolymer of various concentrations and molecular weights, ...
Data extraction from CAD model for rotational parts to be machined at turning centres
(Scientific and Technical Research Council of Turkey, Ankara, Turkey, 1999)
Among the most important data produced and stored is product data. CAD data forms one of many contributors to product data. Although in most circumstances CAD data can be processed within the CIM environment by integrated ...
Catalase adsorption onto cibacron blue F3GA and Fe(III)derivatized poly(hydroxyethyl methacrylate) membranes and application to a continuous system
(Elsevier Science Bv, 1997)
Poly(2-hydroxyethyl methacrylate) (poly(HEMA)) membranes were prepared by W-initiated photopolymerization of HEMA in the presence of an initiator (a-a'-azobisisobutyronitrile, AIBN). An affinity dye, i.e. Cibacron Blue ...
Covalent immobilization of α-amylase onto pHEMA microspheres: preparation and application to fixed bed reactor
(Elsevier Sci Ltd, 1995)
Microspheres of poly(2-hydroxyethyl methacrylate) with and without cross-linker were prepared by suspension polymerization. As the amount of cross-linker increased, the equilibrium water content, enzyme loading, immobilization ...
Graft copolymerization of n-vinyl-2-pyrrolidone on dimethyl sulfoxide pretreated poly(ethylene terephthalate) films using azobisisobutyronitrile initiator
(John Wiley & Sons Inc, 1997)
Poly(ethylene terephthalate) (PET) films were grafted with n-vinyl-2-pyrrolidone (n-VP) using an azobisisobutyronitrile (AIBN) initiator. Films were pretreated in dimethyl sulfoxide (DMSO) for 1 h at 140 degrees C before ...
