Characterization of Rib Cortical Bone Thickness Changes With Age and Sex
… overall economic cost. Of the thoracic injuries, rib fractures are extremely common; present in nearly 94% of severely injured belted occupants. Elderly occupants have increased mortality and morbidity associated with rib fractures. One factor that is thought to influence rib fracture that changes …

Assessment of Rib Failure Mechanisms Using Discontinuum Mechanics Based Modeling Approach
<p>"Coal mine rib failures are major safety and health challenge for coal mines worldwide. The need for clear procedures to evaluate mine rib behavior and to provide an efficient, reliable, and consistent rib control protocol is needed. Understanding coal rib geomechanics is essential for improving …

Optimization of Rib-To-Deck Welds for Steel Orthotropic Bridge Decks
… the welds have been observed in many countries. Rib-to-deck welds need special care since they are directly under wheel loads, which cause large local stress variations and stress reversals. Currently the only requirement by AASHTO bridge code is that the rib-to-deck welds need to be fabricated …

A Study of Imaging Techniques of 3-Dimennsional CT Diagnosis for Rib Fractures
Rib fracture is a common disease occurring in patients with blunt chest trauma and can cause variable complications. However, the sensitivity of simple chest X-ray for the diagnosis of rib fracture is not high and the use of axial CT images of multi-detector computed tomography make us to spend so …

Large Eddy Simulation of Labyrinth Seals and Rib Shapes for Internal Cooling Passges
… unsteady flow features in this study. Different rib shapes in a fully developed ribbed channel are investigated, aiming to improve the heat transfer performance. An immersed boundary method ( IBM ) is used with LES to generate complex geometries. With the use of IBM , the range of geometries can …
