Classical in artificial intelligence not designed to deal with wide continuous environments prone currents. We present novel Fast Marching (FM)-based approach address the following issues. First, we develop an algorithm call FM* efficiently extract 2-D path from discrete representation of...
An Intervention-AUV (or I-AUV), is a hover capable AUV whose primary role direct contact with subsea structures for measurement or physical manipulation of components. The aim the ALIVE project to develop an docking structure which has not been specifically modified use. This paper describes modular AUV, including its distributed software architecture and in particular ADS (Autonomous Docking System). It then outlines sonar video sensor processing techniques used real-time control perform...
The SWIMMER Vehicle is a EU-Thermie funded project to develop prototype autonomous vehicle capable of deploying existing work-class ROVs subsea installations removing the need for continuous surface support vessels and long umbilical cables. To be able accurately position dock large free swimming AUV, at depths up 1000m after transits 10km particularly challenging. deployment configuration mounts ROV above AUV. inactive during deployment, AUV completely self-contained in terms power,...

Abstract There is a vital need to develop in vitro models of the developing human brain recapitulate biological effects that toxic compounds have on brain. To model perineural vascular plexus (PNVP) vitro, which key stage embryonic development, stem cells (hESC)‐derived endothelial (ECs), neural progenitor cells, and microglia (MG) with primary pericytes (PCs) synthetic hydrogels custom‐designed microfluidics device are cocultured. The formation includes networks ECs (CD31+, VE‐cadherin+),...
This paper concentrates on one probably most commercially significant AUV applications: embedded cable and pipeline tracking. A modular approach to this problem has been adopted as the AUTOTRACKER project. The research development is partially funded by European Union companies within offshore industry. system being demonstrated evaluated real pipelines cables using a commercial Survey-AUV. describes AUTOTRACKER's modular, distributed software architecture. It then outlines sensor processing...
This research addresses the problem of coordinating multiple autonomous underwater vehicle (AUV) operations. An architecture has been created that uses multi-agent technology to control and coordinate AUVs in communication deficient environments. By incorporating a simple broadcast system conjunction with real time prediction this can handle limitations inherent operations intelligently vehicles. In efficiency terms mission speed, battery life, robustness goal redundancy is evaluated then...
Many new molecular entities targeted for pharmaceutical applications face serious development challenges because of poor water solubility. Although particle engineering technologies such as controlled precipitation have been shown to enhance aqueous dissolution and bioavailability poorly soluble active ingredients, the data available are results laboratory-scale experiments. These must be evaluated at larger scale ensure that property enhancement is scalable modified drugs can processed on...
Abstract Copper complexes of 3-phenyl-hydrazo acetylacetone and its ortho, meta para carboxy derivatives have been prepared.

The topic of fish welfare in the context commercial fisheries is a difficult one. From traditionally anthropocentric or human‐centred perspectives, fishes are simply objects for humans to use as they see fit.
