Abstract Box girders with steel cantilevers underneath the deck are frequently used in design of composite bridges. Hereby, welded joints between main girder and transverse system have to endure fatigue loads. Current specifications for this joint, e.g., a tapering thickness top flanges at same position transition radius, complex manufacture provide higher resistance than necessary. This articl...

BACKGROUND Altered sensory information arising from damaged knee joint structures has been hypothesized as a contributing factor to persistent muscle dysfunction following injury. METHODS Composite femoral nerve sensory signal was measured in 24 rabbits randomly allocated (8 per group) to receive surgical anterior cruciate ligament (ACL) transection with or without autograft reconstruction or...

ZrO2 has been used for hip and knee joint replacements because of the excellent combination of biocompatibility, low density and corrosion resistance. However, coarse-grained ZrO2 has low wear, abrasion resistance and fracture toughness. One of the methods to improve mechanical properties is generally to refine the grain size. As nanomaterials possess high strength, high hardness, excellent duc...

Artificial neural network is a technique with flexible mathematical structure and lots of characteristics such as parallel distributed processing, nonlinear processing and so on. So the artificial neural network becomes a common method to solve complex problems in research of material science by building a model. This article uses BP and RBF neural network to study the impact from components of...

Partially ordered Markov models (POMMs) are Markov random elds (MRFs) with neighborhood structures derivable from an associated partially ordered set. The most attractive feature of POMMs is that their joint distributions can be written in closed and product form. Therefore, simulation and maximum likelihood estimation for the models is quite straightforward, which is not the case in general fo...

The Air Force Research Laboratory, Space Vehicles Directorate (AFRL/VS), has developed a unique composite Payload Attach Fitting (PAF) shell design. Alliant Techsystems (ATK) and the Boeing Company, Huntington Beach, CA, have developed manufacturing processes and a shell design that incorporates an all-composite forward flange with transverse reinforcement (Z-pinning) at key locations to preven...
