This paper presents a multi-view gait based biometric system that able to work well in various walking trajectories and covariate factors such as clothing, load carrying and speed of walking. Our approach first applies perspective correction to alter the silhouettes from oblique view to side-view plane. Next, joint locations of hip, knees and ankles are estimated based on a priori information o...

To evaluate the limitations of intravenous carotid digital subtraction angiography (DSA) in the diagnosis of carotid disease, studies of 130 patients were reviewed. Factors that resulted in a nondiagnostic study included: (1) misregistration larynx artifact overlying the carotid bifurcation; (2) external carotid or vertebral artery overlying the internal carotid artery; and (3) poor arterial co...

An oblique coronal multiplanar reformatted image (part A) shows the artery of Adamkiewicz (arrow) and the posterior branch (arrowhead) of the left 10th intercostal artery (ICA). An oblique sagittal partial maximum-intensity-projection image (part B) shows that the 10th ICA, the origin ...

A majority of laboratory-driven side impact injury assessments are made using post mortem human subjects (PMHS) under the pure 90-degree lateral mode. Because real-world injuries occur under pure and oblique modes, this study was designed to evaluate injury metrics and injury mechanisms with PMHS under the latter vector. Anthropometrical data were obtained and functional x-rays were taken. Spec...

127  AbstractAn Experiment is conducted to determine the effect of various parameters on performance of tube in oblique loading and optimize its crushing in the given environment..The Experiment was designed using Taguchi technique and the parameters like material density , tube thickness ,foam density and angle of loading were selected which have more influence on energy absorption ,specific ...

*The superficial medial collateral ligament and other medial knee stabilizers-i.e., the deep medial collateral ligament and the posterior oblique ligament-are the most commonly injured ligamentous structures of the knee. *The main structures of the medial aspect of the knee are the proximal and distal divisions of the superficial medial collateral ligament, the meniscofemoral and meniscotibial ...

A cardiac-tailored framework for 3D Diffusion Tensor MRI tractography is developed and used to characterize myofiber architecture in normal and remodeled myocardium. We show that myofibers in the subepicardium of the remote infarct zone become less oblique (more circumferential) as the heart dilates and remodels. This fiber realignment may play an important role in the loss of contractile funct...

this study compares the functional capabilities of different metacarpal fixation constructs under physiological loadings in an attempt to identify the optimal construct rather than the strongest one. one hundred and twenty-six preserved human metacarpals were mechanically tested after oblique osteotomies and internal fixation. maximum load to failure, average structural rigidity, and energy abs...

Buckling strength of composite latticed cylindrical shells is one of the important parameters for studying the failure of these structures. In this paper, new governing differential equations are derived for latticed cylindrical shells and their critical buckling axial loads. The nested structure under compressive axial buckling load was analyzed. Finite Element Method (FEM) was applied to mode...
