Hydraulic Transportation of Solid Material (2nd Report)

The hydraulic transportation of thickened sludges

Industries which pump sludges are under continuous pressure to decrease water content, and increase concentration. Environmentally superior disposal techniques are demanding that such sludges have high mechanical strength properties. This results in a sludge with an increasing viscous character. At high concentration, the viscous forces – which are usually highly non-Newtonian and yield stress ...

Application of Chaos Theory in Hazardous Material Transportation

Risk factors are generally defined and assigned to road networks, as constant measures in hazmat routing problems. In fact, they may be dynamic variables depending on traffic volume, weather and road condition, and drivers' behavior. In this research work, risk factors are defined as dynamic variables using the concept of chaos theory. The largest Lyapunov exponent is utilized to determine the ...

The 2nd order local-image-structure solid

Characterization of 2 nd order local image structure by a 6-D vector (or jet) of Gaussian derivative measurements is considered. We consider the affect on jets of a group of transformations – affine intensity-scaling, image rotation and reflection, and their compositions – that preserve intrinsic image structure. We show how this group stratifies the jet space into a system of orbits. Consideri...
