    The paper examines the causes of ten of history's worst engineering disasters and the lessons that could be learnt from them. The ten engineering disasters stretching from the sinking of the Swedish ship Vasa in the 17th century to the explosion of the Chernobyl nuclear reactor at the end of the 20th century illustrate what lessons are learnt when things go wrong. There will always be failures or disasters as engineers and designers push the boundaries by building taller buildings, longer bridges, or by reaching further into space. Each time there is a failure or disaster, changes are made and regulations introduced only to be outstripped by further developments. View full abstract»

  • What would you do?

    The psychology of human behaviour in times of disaster has become an essential discipline used by engineers to reduce the risk that people will die when a building is hit by fire, earthquake or terrorist attack. What became clear is that more lives may well have been saved had people reacted differently. Rather than dash for the nearest exit, most did the opposite: they prevaricated. A study by the US National Institute of Standards and Technology (NIST) found that even those who managed to escape from the towers waited an average of six minutes before heading for the stairs. Some dallied for half an hour. These findings lent credence to a theory already gaining support among risk experts: that when disaster strikes, people behave in unexpected and irrational ways. About half of the interviewees said they hung around before deciding to escape, either waiting for more information about the situation from colleagues or officials, or collecting things to bring with them, changing their shoes, locking things into safes, going to the toilet, finishing emails, filing papers, making phone calls or shutting down their computers. When they did leave, they descended the stairs without great urgency and considerably more slowly than the building's safety engineers had forecast, apparently because of congestion from the large number of people trying to descend, even though the building was far from full.

    Seventy years on, airships are finally emerging from the shadow of the Hindenburg disaster.The JHL-40, which will be developed and built by Boeing, combines a neutrally-buoyant semi-rigid helium envelope with four Chinook helicopter rotors. The inert gas provides enough lift to support the aircraft, leaving the rotors to lift cargo - 40t at a time - and propel it at up to 70 knots (130km/h) over its range of 320km. View full abstract»

    Picoprojector is a miniature movie projector designed for inclusion in handheld devices such as phones. The technology is already playing to both the enterprise and consumer markets simultaneously but the question is, how does a severe economic downturn affect a promising technology like this?

  • Forecasting flood

    One of the ways flood risk can be determined is by using very accurate 3D digital maps, captured from aircraft-mounted lasers. Ambiental is using this technique to assess the risk of flooding at critical utility sites across the UK. The project, undertaken on behalf of one of the UK's largest water companies, uses LiDAR (Light Detection and Ranging) data supplied by aerial survey specialist Bluesky to gauge the likelihood, extent and depth of potential flooding as part of a review of flood defence measures at each of the five sites. The Bluesky data is part of a 3D terrain map, available online, that covers most of England and Wales including all major urban centres, coastal areas and flood plains. The high-resolution LiDAR data, supplied by Bluesky, was used to map each risk in 3D to ascertain the spatial distribution of different flood depths. The results of these assessments were used for business planning purposes, specifically within cost-benefit analysis for flood defence measures at each site. View full abstract»

  • A flood watershed

    The paper states that remote control and monitoring is the future for flood prevention in low-lying areas. Around five million people live in flood risk areas in England and Wales, according to the Environment Agency. Some parts of the UK are even below sea level, leaving them constantly at risk from permanent flooding and water logging. However, the flood risk can be reduced by drainage districts, which have been set up to prevent flooding by providing flood protection and water-level management schemes, which involves improving and maintaining rivers, drainage channels and pumping stations to evacuate water.

    The paper mentions that as oil-rich Abu Dhabi builds the 'world's greenest' city, carbon-heavy China has designs on an eco-friendly metropolis. Exactly when the world decided eco-villages just weren't big enough is difficult to gauge, but for today's environmentally friendly developments, size is everything. Forget any ideals of holistic living and group-hugs; the present-day eco-city is big, bold, sophisticated and requires a lot of cash. View full abstract»

  • Play the IT security game fun for all the enterprise!

    IT security is no game, and those who practice it can expect no respite from the onslaught of online threats except for this game. You have to steer your organisation past the hackers, script kiddies and disgruntled employees. Your future as CIO is at stake, and your decisions could spell the difference between winning or losing. All you need are a couple of standard games dice, and some form of place marker for each player e.g., a tiddly-wink. Start the game with three products or services you can buy that you think should enhance your security. As you move around the board, you find out whether or not they work. One piece of bad planning can send you back to the beginning. When you land on a Random Event, and you haven't implemented the necessary protection, you take the full impact. If you have, you get to laugh in the face of chance and roll again. Serpents of unforseen fate lurk elsewhere: green slithers you up, while red slithers you down. View full abstract»

    Petrol-free passenger cars are no longer the sole province of small specialist manufacturers. Ford is one of many car-makers planning to target the growing market for hybrid and all-electric cars. The Ford strategy calls for the introduction of new hybrids, a plug-in hybrid electric vehicle (PHEV) and battery electric vehicles (BEVs) based on two new global product platforms. The plan calls for in 2011 a pure BEV - using lithium-ion battery technology - as a passenger car in North America. View full abstract»

    It may describe itself as "a global infrastructure, finance and media company." but with interests from everyday light bulbs to fuel cell technology, and from carbon composites to cleaner, more efficient jet engines, General Electric Company (GE) knows that it can't succeed without also investing in research and development - including long- term research. The paper presents the efforts of GE's global research center which is committed not only for product lines' advanced technologies but also finding ways to alternative energy and environmental technologies.

  • The net effect

    Is life on the Internet having a disastrous effect on our children's minds? Or are they developing into the ultimate multi-taskers? E&T finds out. Internet access is everywhere these days in schools, households, and in many cases even the bedrooms from which children may soon lead us into the next phase of human evolution or reveal themselves to have been damaged by too much time spent in the virtual world. An overwhelming 99 per cent of children and young people aged eight to 17 regularly use the Internet in the UK, according to communications regulator Ofcom. In 2007 these children spent an average of 13.8 hours online per week, almost twice as long as they did in 2005. Interviews conducted at the end of 2008 by market research agency ChildWise in more than 90 schools in England, Wales and Scotland found that 37 per cent of children now go online in their own rooms, including one in five of five-to-eight-year olds. "This year has seen a major boost to the intensity and the independence with which children approach online activities," says the 'ChildWise Monitor Report 2008-09'. View full abstract»
