The basic method used is the Finite Element Method but substructuring techniques are appropriate as a means whereby the maximum problem siz

Niklas Luhmannnant motion of a directly excited mode of vibration is suppressed, while other modes respond in a vigorous and catastrophic manner at frequencies far removed from the excitation frequency. Such responses have been observed in a number of vibratory systems having as a common feature subsystems of con

Heavy metals originating from anthropogenic activity have significantly degraded clean fres

The stabilization and solidification of sludge enable the reuse and recycling of sludge from being disposed into the landfill, a paradigm shift in the waste management hierarchy. Due to the variation of sludge properties (including toxicity) and reuse applicatio
