Optimum design accounting for the global nonlinear behavior of the model
A Novel Curvature Based Algorithm for Automatic Grading of Retinal Blood Vessel Tortuosity
. Simplicity of the algorithm, low computational
burden and an excellent matching to the clinically perceived tortuosity are the important features of the proposed algorithm.To measure tortuosity, we use curvature which is an indicator of local...
Curvature Effects on Hemodynamics of S-shaped Arteries
The purpose of this study is to investigate the effect of Reynolds number and sweep angle on the blood flow patterns in S-shaped bends, resembling the femoral artery. The numerical simulations of steady flows in S-shaped ...
A New Feature Descriptor for Image Denoising
, based on the difference curvature and the gradient of the image,
we introduce a new feature descriptor. For demonstrating the effectiveness of the new feature
descriptor, we use it in constructing a new diffusion-based denoising model. Experimental...
Structural similitude for vibration response of laminated cylindrical shells with double curvature
shells. Particular emphasis is placed on the case of free vibration of cross-ply laminated
cylindrical shells with double curvature. The results presented herein indicate that, for free vibration responses of
laminated cylindrical shells...
Effect of Impactor Shape and Impact Energy on Bruise Characteristics in Different Apple Varieties
A case necessary to develop postharvest mechanization is to have enough information to decrease mechanical damage for each crop. This research performed to determine and compare the susceptibility of apple varieties to ...
Investigation of Corner Rounding Effects on the Performance of a Supersonic Air Intake
In this research, flow is simulated numerically through and around a mixed-compression intake to investigate effects of corner rounding on intake performance at free stream Mach numbers of 1.8, 2 and 2.2 and at zero degrees ...
Reconstruction of Surface Curvature from the Triangular Flat Meshes for the Calculation Radar Cross Section of Electrically Large Objects
the surface curvature and the resulting changes in the curvature of the reflected wavefront. As a result the accuracy of radar cross section prediction decreases. This paper uses a bilinear approximation method to estimate the normal vector variations...
