Abstract:

The P.I. spent the summer at the Naval Surface Warfare Center NSWC in Dahlgren, VA, working, on the project and providing general technical assistance and education to NSWC personnel. Productive collaboration included development of Matlab demonstration suite with Ron Gross, optimizing RF absorption characteristics of multilayer rubber surfaces with Jack Shuler, and wavelet theory with Addison Jump. Ph.D. student Steven Moore was self supporting for 1999 the grant instead supported two Masters students Alan Calder and Kevin Conrad who did supporting software development. Research accomplishments include implementation of simulated annealing algorithm implementation of 1-D and 2-D Discrete Wavelet Transform parameterization of various wavelet spaces orthonormal wavelets, symmetric complex orthonormal wavelets, symmetric biorthogonal wavelets of odd and even lengths, and symmetric biorthogonal wavelets of odd and even lengths having specified order of regularity development of wavelet demonstration software suite with Ron Gross NSWC presentation of course Wavelets and Filter Banks to NSWC personnel application of simulated annealing to optimize RF absorption characteristics of multilayer surfaces generalization of wavelet transform to M-band wavelets algorithm to generate a wavelet filter bank using any filter whatsoever as the analysis filter implementation of an algorithm to parameterize all M-band paraunitary filter banks.
