1 Neuromusculoskeletal disorders affecting walking ability are often difficult to manage, in part due to 2 limited understanding of how a patient’s lower extremity muscle excitations contribute to the patient’s 3 lower extremity joint moments. To assist in the study of these disorders, researchers have developed 4 electromyography (EMG) driven neuromusculoskeletal models utilizing scaled generi...

We provide a sensor fusion framework for solving the problem of joint ego-motion and road geometry estimation. More specifically we employ a sensor fusion framework to make systematic use of the measurements from a forward looking radar and camera, steering wheel angle sensor, wheel speed sensors and inertial sensors to compute good estimates of the road geometry and the motion of the ego vehic...

In this paper, influence of riveting process parameters, namely, riveting force, sheet thickness, friction coefficient and clearance fit are investigated on residual stress field and fatigue life of single riveted lap joint of AA2024 type. According to the effect of riveting induced residual stresses on fatigue life of riveted lap joint, these parameters are optimized to maximize the residual s...

In this study, a specimen geometry for testing finger joints was developed using finite element simulation and proofed by experimental testing. Six different wood species three adhesives were used finger-jointing specimens. With the test geometry, bonding strength of determined without usual self-locking joint. Under load, introduces maximum stress at beginning bond line (adhesive zone). Howeve...

Computational models may have the ability to quantify the relationship between hip morphology, cartilage mechanics and osteoarthritis. Most models have assumed the hip joint to be a perfect ball and socket joint and have neglected deformation at the bone-cartilage interface. The objective of this study was to analyze finite element (FE) models of hip cartilage mechanics with varying degrees of ...

In this letter, we address geometry coding of 3-D mesh models. Using a joint prediction, the encoder predicts vertex positions in the layer traversal order. After we apply the joint prediction algorithm to eliminate redundancy among vertex positions using both position and angle values of neighboring triangles, we encode those prediction errors using a uniform quantizer and an entropy coder. Th...

We studied the anatomy of the patellofemoral joint in the axial plane on cryosections from a cadaver knee and on MR arthrotomograms from 30 patients. The cryosections revealed differences in the geometry and anatomy of the surface of the articular cartilage and corresponding subchondral osseous contours of the patellofemoral joint. On the MR arthrotomograms the surface geometry of the cartilage...

Females demonstrated 2-9 times higher ACL injury rate, narrow notch width and higher joint laxity in multi-planar directions [1,2]. One of potential ACL injury mechanisms is ACL impingement against the lateral wall of the femoral intercondylar notch [3], expressed as elongated and deformed ACL geometry [3] and contact area and contact pressure between the ACL and the intercondylar notch [4]. Ho...

The elbow joint is a complex structure that provides an important function as the mechanical link in the upper extremity between the hand, wrist and the shoulder. The elbow's functions include positioning the hand in space for fine movements, powerful grasping and serving as a fulcrum for the forearm. Loss of elbow function can severely affect activities of daily living. It is important to reco...
