On 31 May 2009 a unique and versatile hybrid vehicle dived 10,902m below the surface of the Pacific Ocean to the bottom of the 'Challenger Deep' in the Mariana Trench. The Nereus is only the third vehicle ever to have descended this far - to the deepest part of the world's oceans. The revolutionary unmanned craft was designed by engineers at Woods Hole Oceanographic Institute (WHOI) in Massachusetts on a budget of only $6m. Nereus is set to open up the exploration of the extreme depths to science, and its design concept will have extensive repercussions on 'conventional' ROV design in the oil and gas and military sectors. Project manager and principal developer Andy Bowen talked to E&T about what makes it special. Its hybrid nature means that Nereus can be operated as a pre-programmed, free-flying autonomous underwater vehicle (AUV) to survey broad areas. Conversion into its tethered, piloted ROV (remotely-operated vehicle) mode only takes six hours and allows it to inspect specific areas of interest identified in the flyby. This makes it especially flexible and versatile. Freed of the constraints of heavy steel cables, with a robot like Nereus we can now explore virtually anywhere in the ocean. - Author(s): L. Murray

The UK appears to be falling behind with the creation of HD content, particularly when compared with the US. E&T looks at the measures UK broadcasters are taking to catch up. Last year, consumer display manufacturer LG released the results of a UK survey which demonstrated a great deal of confusion and subsequent distrust of high-definition (HD) technology. - Source: Engineering & Technology, Volume 4, Issue 14, p. 34 –35

Thirty years ago, the military- industrial complex practically owned the electronics component business. Big contracts for weapons programmes helped fund many of the top names in semiconductors, including Intel. Even at the end of the 1980s, Intel was still designing processors, such as the 1960, that were aimed squarely at military users.But, ten years prior to that, a the personal computer had s begun to change the world: more and more of the market for electronics shifted to the fickle consumer sector. Once the consumer market dominated the business - according to the Semiconductor Industry Association PCs and cellphones now absorb 60 per cent of the world's chips - interest from the big suppliers slipped away. This paper discussses possible solutions to overcome the problem the defence sector has. One possible solution is to move to commercial off-the-shelf (COTS) products that are not designed with the military in mind. But moving to COTS products is not easy. The RoHS legislation that banned lead and other heavy metals from use in most components plays a part in the concerns over COTS as well as helping to take parts off the market. Rather than continuing to make the older parts that contain lead, a number of manufacturers have shifted production entirely to the lead- free versions. But reliability issues encountered in the world of consumer products, such as 'tin whiskers' shorting out contacts, have worried engineers in the defence sector. Also, as manufacturers wind down production, the fraudsters move in, offering counterfeit parts to companies desperate for replacements or continuing supplies for production.reliability. - Author(s): M.

Olympic, Titanic and Britannic have all been surrounded in controversy and mystery since the day they were built. Britannic, which was launched in 1914, had been redesigned to correct the defects that had played such a crucial role in the sinking of the Titanic. Dr Robert Ballard is interested in using Britannic as a prototype project for his telepresence idea for Titanic. There is also the possibility to use ROVs to look inside. The concept of underwater cameras these days is not quite as far-fetched as it might have been ten years ago. - Author(s): M. Langdon

As IT becomes ever-more complex, sophisticated, and extensive, the task of network management is to maintain levels of user expectation against growing technological challenges. To many of those within the IT so tasked it is a thankless undertaking, as no sooner has one performance objective been met than new problems arise that discombobulate the original plan. It is, arguably, an ambition of containment rather than expansion, and even the quest for autonomic management, or self-healing networks, must be seen in that light, against a continuous background of cost constraints. - Author(s): R. Coupland and J. Hayes

Service level agreements - SLAs - have been the cornerstone of the contract between suppliers and consumers of ICT services, whether these are internally or externally sourced. Yet despite plenty of time seemingly for SLAs to mature and bed down, there are signs of discontent on both sides of the camp, with some enterprises criticising the culture of blame surrounding SLAs whereby vendors pay damages when the promised level of service is not met. - Author(s): M.

Active sonar is being 'trained' to identify sea mammals in a bid to cut the costs of monitoring tidal turbines and speed up the development of marine energy in Britain. The sonar is just one part of the technological response to a very human - and animal - problem. Will underwater turbines harm seals, dolphins and sea birds? And how would we know if they did? The world's largest environmental marine-energy monitoring project in Northern Ireland has not found that tidal turbines are having a measurable impact on seals, dolphins and sea-birds after three years of a five-year study. But, while marine biologists say it could take a decade to be sure, developers say more expensive monitoring could cripple the fledgling tidal energy industry. Academics are hoping technology might offer a compromise. - Author(s): S. Davis
