Towed Array Response to Ship Noise: A Near-Field Propagation Problemin the environment can be remediated using a range of techniques including nanotechnologies. Environmental remediation techniques use various approach to remove or degrade environmental pollution in soils, waters, groundwater, and air. There are two different strategies to apply the nanotechnologies

Three-Dimensional FFP Model of Acoustic— and Elastic Wave Propagation in Horizontally Layered Mediaides, and plastic film. Characterized by high BOD and ammonia, agricultural wastewater is generally degraded by microbial technique, including natural treatment and anaerobic or aerobic techniques. However, long reaction period and remnant of a persistent organic cannot be solved appropriately. Rece

Second Moments of the Pressure Field Near a Smooth Causticly parallel because one mask can be used to expose millions of features at the same time. The minimum size of the features that can be created with conventional lithography is of the order of half the wavelength of the light being used. Extensions of optical lithographic techniques, involving deep u
