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 ...
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 ...
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) ...
A numerical study of laminar heat convection in ducts of irregular cross-sections
(Pergamon-Elsevier Science Ltd, 1997)
Forced convective heat transfer during hydrodynamically fully developed laminar fluid flow inside ducts of irregular cross section is analyzed utilizing numerical methods. The elliptic grid generation technique is used to ...
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 ...
Analytical solution for continuous-time Kalman tracking filters with colored measurement noise in frequency domain
(Ieee-Inst Electrical Electronics Engineers Inc, 1994)
New expressions are given for analytical solutions to the steady-state Kalman gains of the two-state exponentially correlated velocity (ECV) and the three-state exponentially correlated acceleration (ECA) tracking filters ...
Analysis of energy flow in thick plate structures
(Pergamon-Elsevier Science Ltd, 1997)
At sufficiently high frequencies: where the structural wavelength is much smaller than the thickness of the structure, the rotational inertia and transverse shear effects become increasingly important. In this study the ...
Analysis of orthotropic plate structures by the direct-dynamic stiffness method
(Pergamon-Elsevier Science Ltd, 1995)
