BACKGROUND Vascular Ehlers-Danlos syndrome (vEDS), also known as EDS type IV, an inherited disorder of connective tissue, results from mutations in the gene encoding type III procollagen (COL3A1). Affected patients are at risk for arterial dissection or rupture, the main cause of death. To understand the pathogenesis of the vascular lesions, we used a biomechanical approach and determined stead...

Endothelial dysfunction, believed to underlie the structural changes of atherosclerosis, is a systemic phenomenon. Despite this, the radial artery has been considered as devoid of atherosclerosis and is commonly used as a conduit in coronary artery bypass grafting (CABG). Recently, histological study has shown intimal hyperplasia and other structural changes consistent with early atherosclerosi...

Recent in vivo studies, utilizing ultrasound contour and speckle tracking methods, have identified significant longitudinal displacements of the intima-media complex, and viscoelastic arterial wall properties over a cardiac cycle. Existing computational models that use thin structure approximations of arterial walls have so far been limited to models that capture only radial wall displacements....

In this work, we investigate the dynamic response of a solid phase formed during unidirectional solidification below a cooling top wall of a square cavity filled with distilled water and subjected to timevarying heating temperatures at its bottom wall. Assuming a quasisteady state condition, we have formulated a one-dimensional model that predicts the average thickness of the forming solid phas...

−57− This paper explores the use of Ultra-Wideband (UWB) radar for tracking multiple moving humans. Because the ability to track human movement is useful for the wide range of security and safety applications, a number of technologies have been pursued for human tracking. Computer vision has limited performance in poor visibility conditions, while the performance of infrared imagers can be temp...

In recent years, soft computing methods, like fuzzy logic and neural networks have been  presented and developed for the purpose of mobile robot trajectory tracking. In this paper we will present a fuzzy approach to the problem of mobile robot path tracking for the CEDRA rescue robot with a complicated kinematical model. After designing the fuzzy tracking controller, the membership functions an...

The behavior of bubbles traveling in the proximity a tilted wall is studied experimentally to understand fundamental sliding motion inside turbulent boundary layers along an inclined wall. qualitative visualization confirms contribution bubble buoyancy on for negative and positive inclinations channel. An opto-acoustic combined measurement technique adopted explore motion. Liquid velocity profi...
