Elsicon Incorporated proposes to develop an optical demultiplexer appropriate for use in high bandwidth fiber-optic communication systems. The demultiplexer will be capable of reducing an optical input bit stream with an aggregate bit rate of greater than 100 Gbits/sec down to a 1 Gbit/sec baseband rate. Therefore, by distributing the full serial data stream among an array of these devices, ultrah ...

Shipboard structures employing composites typically use glass/vinyl ester (VE) manufactured with vacuum assisted RTM. This composite system offers reduced weight, no corrosion and improved signature performance but lacks the fire performance characteristics required for shipboard use. Phenolic resins (PH) provide outstanding fire performance but are difficult to process and offer lower structur ...

The overall objective of this work is to develop a general-purpose CFD-based, shape optimization tool for robust and efficient aerodynamic shape optimization. Shape optimization is a technology where design optimization algorithms are coupled with geometry/shape deformation tools and engineering analysis codes such as computational fluid dynamics and structural analysis. The optimization algorit ...

Ultrafiltration membranes offer great potential for compact, low cost clean-up of Navy surface ship graywater and blackwater. A major limitation of these ultrafiltration membranes is significant loss in flux with time associated with membrane fouling from proteins, polysaccharides, and other waste products. Backflushing can only be used to a limited extent. Chemical treatments are undesirous si ...
