Presented is a method for estimating the 2D planar position, velocity, and orientation states of a tagged shark. The method is designed for implementation on an Autonomous Underwater Vehicle (AUV) equipped with a stereo-hydrophone and receiver system that detects acoustic signals transmitted by a tag. The particular hydrophone system used here provides a(More)

We present a methodology and algorithm for the reconstruc­ tion of three dimensional geometric models of ancient Maltese water stor­ age systems, i.e. cisterns, from sonar data. This project was conducted as a part of a four week expedition on the islands of Malta and Gozo. During this expedition, investigators used underwater robot systems ca­ pable of(More)
Behavior of a series of fusion proteins of varying charge in reversed micellar extraction was studied. The proteins consisted of the enzyme glucoamylase from Aspergillus awamori joined to short peptides containing from 0-10 additional aspartate residues. The fusions were partitioned into two different cationic surfactant systems, one based on the surfactant(More)
We have investigated the use of charged fusion tails with the enzyme glucoamylase in reversed micellar extraction. The addition of the charged tails increased the fraction of enzymatically active protein recovered at a given pH, with the tails containing the largest number of charges being recovered at the highest level. The series of mutations also allows(More)
