Pulsatile Velocity Measurements in a Model of the Human Abdominal Aorta Under Resting Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Oscillations in near-wall velocity direction have been found to correlate with atherosclerotic plaque localization in the carotid sinus bifurcation. However, it remains unproven whether these ...
Integrated Planning Information Systems: Disaster Planning Analysis
Publisher: American Society of Civil Engineers
Abstract: This research contributes to the theoretical basis for design of integrated planning information systems. The research provides a framework for integrating relevant knowledge, theory, methods, and technology. The requirements ...
Statistical Designation of Traffic Control Subareas
Publisher: American Society of Civil Engineers
Abstract: A method for identifying control subareas in traffic signal networks has been developed and tested with data from the Miami, Florida, business district. The procedure combines the use of cluster and discriminant analysis ...
Improved User Equilibrium Based Method for Estimating Trip Tables
Publisher: American Society of Civil Engineers
Abstract: An optimal trip table correction function for the user equilibrium based trip table estimation problem is derived and used in place of Turnquist and Gur's heuristic trip table correction function. The derivation of this ...
Modeling of Deformation-Accelerated Breakdown of Polylactic Acid Biodegradable Stents
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The use of biodegradable polymers in biomedical applications has been successful in nonload bearing applications, such as biodegradable implants for local drug delivery, and in simple load bearing ...
Frequency Dependence of Dynamic Curvature Effects on Flow Through Coronary Arteries
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The flow through a curved tube model of a coronary artery was investigated computationally to determine the importance of time-varying curvature on flow patterns that have been associated with ...
Blood Flow in Stented Arteries: A Parametric Comparison of Strut Design Patterns in Three Dimensions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Background: Restenosis after stent implantation varies with stent design. Alterations in secondary flow patterns and wall shear stress (WSS) can modulate intimal hyperplasia via their effects on ...
Stress Distribution in a Circular Membrane With a Central Fixation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Clinical interventions can change the mechanical environment of the tissues targeted for therapy. In order to design better procedures, it is important to understand cellular responses to altered ...
Trans-Thrombus Blood Pressure Effects in Abdominal Aortic Aneurysms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: How much and how the thrombus supports the wall of an abdominal aortic aneurysm (AAA) is unclear. While some previous studies have indicated that thrombus lacks the mechanical integrity to ...
Comparison of Near-Wall Hemodynamic Parameters in Stented Artery Models
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Four commercially available stent designs (two balloon expandable—Bx Velocity and NIR, and two self-expanding—Wallstent and Aurora) were modeled to compare the near-wall flow characteristics of ...
