some considerable damage to steel structures during the hyogo-ken nanbu earthquake occurred. among them, many exposed-type column bases failed in several consistent patterns, such as brittle base plate fracture, excessive bolt elongation, unexpected early bolt failure, and inferior construction work, etc. the lessons from these phenomena led to the need for improved understanding of column base...

background : biomechanical factors are known to be important in knee osteoarthritis (oa) development and progression. this study was designed to determine changes of hamstrings muscle activation, knee adduction moment and ankle rotation angle in two knee osteoarthritis (mild and moderate) and a healthy control group. methods: 16 females (10 with mild and 6 with moderate medial knee osteoarthr...

curve flexibility in adolescent idiopathic scoliosis (ais) was one of the major concerns of spinal surgeons since the evolution of surgical correction techniques. in this respect, many tried to identify which criteria denote more rigid curve. in the present study, we aimed toward determining important factors influencing ais curve flexibility on supine bending films. we assessed radiographs of ...
The completeness property of a set of invariant descriptors is of fundamental importance from the theoretical as well as the practical points of view. In this paper, we propose a general approach to construct a complete set of orthogonal Fourier-Mellin moment (OFMM) invariants. By establishing a relationship between the OFMMs of the original image and those of the image having the same shape bu...
A method is described for deriving, from digitiied imager.objective measures that correlate strongly with simple perceptual judge-ments on the same images. Each measure is the normalized variance of animage obtained by convolving the original image with a specific localoperator. This operator is designed to optimize the correlation between theparticular percept and the objec...
The shoe-surface interface has been implicated as a possible risk factor for anterior cruciate ligament (ACL) injuries. The purpose of this study is to develop a biomechanical, cadaveric model to evaluate the effect of various shoe-surface interfaces on ACL strain. There will be a significant difference in ACL strain between different shoe-surface combinations when a standardized rotational mom...
