Femoral artery bypass grafts have a predilection for failure at the distal anastomosis due to restenosis, within a short period of time, the cause of which has been attributed to altered haemodynamics. This study proposes ...

Water purification technologies such as microfiltration/ultrafiltration and reverse osmosis utilize porous membranes to remove suspended particles and solutes. These membranes, however, cause many drawbacks such as a ...

Fibre reinforced composites exhibit a gradual damage accumulation to failure, with a multitude of hierarchical dissipative mechanisms responsible for the deterioration of mechanical properties. In order to predict failure ...

Despite all current measures taken to assure their safety, aircraft are still crashing. Since 1944 there has been a global organization, International Civil Aviation Organization (ICAO), focused on providing rules for ...

Coronary artery disease is atherosclerosis of the coronary arteries that results in blockages or narrowing of the arterial wall, is caused by the accumulation of lipid-laden atherosclerotic plaque. Drug eluting stents ...

Ratcheting is defined as the accumulation of plastic strains during cyclic plastic loading. Modeling this behavior is extremely difficult because any small error in plastic strain during a single cycle will add to become ...

In-situ micro-mechanical testing of small composite laminates has been carried out under SEM where video recordings allowed examination of the evolution of damage processes at the microscale. Samples are tested under three- ...

Controlling wettability by varying surface chemistry and roughness or by applying external stimuli is of interest for a wide range of applications including microfluidics, drag reduction, self-cleaning, water harvesting, ...

Small to Medium Enterprise (SME) performance is a function of the composite of the decision-making processes within the enterprise. Owner managers are conscious of the gap in their decision-making efficacy and acknowledge ...

Turbulent wing-tip vortices are an extremely important fluid dynamics phenomena for their negative impact in several applications. Despite the many numerical and experimental studies conducted on this particular flow, ...
