In this study, the finite element model of long, thin and flexible carbon fiber reinforced composite cover design prepared using Unigraphics NX program CAD module was analyzed in ANSYS program. Topography optimization performed by transferring analysis results to GENESIS The rib created after combined with initial necessary corrections were made based on topography guide. design, conventional m...

SUMMARY We propose a two scale asymptotic method to compute the effective effect of a free surface topography varying much faster than the minimum wavelength for 2-D P-SV elastic wave propagation. The topography variation is assumed to be non-periodic but with a de-terministic description and, in the present paper, the elastic body below the topography is assumed to be homogeneous. Two asymptot...

PURPOSE Lipofuscin (LF) accumulation within RPE cells is considered pathogenic in AMD. To test whether LF contributes to RPE cell loss in aging and to provide a cellular basis for fundus autofluorescence (AF) we created maps of human RPE cell number and histologic AF. METHODS Retinal pigment epithelium-Bruch's membrane flat mounts were prepared from 20 donor eyes (10 ≤ 51 and 10 > 80 years; p...

S U M M A R Y Dynamic stresses developed in the deep crust as a consequence of flow of weak lower crust may explain anomalously high topography and extensional structures localized along orogenic plateau margins. With lubrication equations commonly used to describe viscous flow in a thin-gap geometry, we model dynamic stresses associated with the obstruction of lower crustal channel flow due to...

This paper presents a novel image matching method for multi-source satellite images, which integrates global Shuttle Radar Topography Mission (SRTM) data and image segmentation to achieve robust and numerous correspondences. This method first generates the epipolar lines as a geometric constraint assisted by global SRTM data, after which the seed points are selected and matched. To produce more...

Many engineering fields, including tribology and MEMS, seek to use or alter the behavior of the system at the surface or at the interface between surfaces. Thus, the topography of the surface is of great interest and must be included in finite element simulations. Four methods for generating normally distributed rough surfaces using APDL are proposed. The resulting geometry, meshes, and solutio...

  Background: Some studies have previously shown that geometry of proximal femur can affect the probability of fracture and type of fracture. It happens since the geometry of the proximal femur determines how a force is applied to its different parts. In this study, we have compared proximal femur’s geometric characteristics in femoral neck (FNF), intertrochanteric (ITF) and Subtrochanteric (ST...

Effects of tree species diversity on decomposition can operate via a multitude of mechanism, including alterations of microclimate by the forest canopy. Studying such effects in natural settings is complicated by the fact that topography also affects microclimate and thus decomposition, so that effects of diversity are more difficult to isolate. Here, we quantified decomposition rates of standa...
