PlySim meets composite structural engineering challenges; results include a 500+ percent improvement in modeling productivity, plus a better blade and a growing business
Siemens – According to RenewableUK, the trade and professional body for the United Kingdom (U.K.) wind and marine renewables industries, the U.K. is the windiest country in Europe – so much so that this free fuel could meet the power needs of the country several times over. RenewableUK notes that there are over 4,000 wind turbines currently operational in the U.K., with a total capacity of 7.391 gigawatts (gw), enough to power over 7 million homes. It is estimated that by 2016, there will be 8 gw of offshore capacity installed, with a total of 18 gw by 2020. However, there are significant engineering challenges associated with such substantial growth that companies such as PlySim, based in Edinburgh, U.K., are already successfully addressing.
PlySim Ltd. (Plysim) is a composite structural engineering consultancy, with heavy focus on finite element analysis (FEA). Its main markets are in the renewables sectors (wind, wave and tidal) as well as marine and civil engineering. Malcolm Wadia, director of PlySim, says, “We work with clients worldwide on the analysis of large complex structures in composite materials, having materials tested if necessary, developing the whole structural design prior to analysis, and providing certification reports and full-scale test specifications for each design, if required. Ultimately, we provide the 2D ply layup and production drawings.” more>
Human Factors Research Helps Accelerate Mission Planning
By John Toon – The key to a successful flight mission is planning – sometimes several hours of it. Georgia Tech Research Institute (GTRI) specialists in human factors and human computer interfaces are working with NAVAIR PMA-281, Strike Planning and Execution Systems in Patuxent River, Maryland, to streamline the current mission planning process and identify user interface requirements supporting multi-domain mission management in next-generation naval planning capabilities.
With guidance from the GTRI researchers, the project will improve usability of the mission planning software tools, creating a more consistent and intuitive screen design that’s easier to learn and more logical to follow. This effort could benefit all Department of Defense (DoD) agencies for collaborative mission planning.
“We are working with Navy and Marine Corps aviators to identify areas in mission planning where work-flow can be streamlined, reducing the time required to mission plan,” said Marcia Crosland, project director for GTRI’s Joint Mission Planning System (JMPS) User Interface Design and Usability efforts. “Our task has been to define the user interface concepts and decision-making tools to help reduce the time required for mission planning. We’ve created detailed designs and specifications to direct current and future development of mission planning systems.” more>

By Simon Wren-Lewis – Or maybe the middle ages, but certainly not anything more recent than the 1920s. Keynes advocated using fiscal expansion in what he called a liquidity trap in the 1930s. Nowadays we use a different terminology, and talk about the need for fiscal expansion when nominal interest rates are stuck at the Zero Lower Bound or Effective Lower Bound.
When monetary policy loses its reliable and effective instrument to manage the economy, you need to bring in the next best reliable and effective instrument: fiscal policy.
The Eurozone as a whole is currently at the effective lower bound. Rates are just below zero and the ECB is creating money for large scale purchases of assets: a monetary policy instrument whose impact is much more uncertain than interest rate changes or fiscal policy changes (but certainly better than nothing). The reason monetary policy is at maximum stimulus setting is that Eurozone core inflation seems stuck at 1% or below. Time, clearly, for fiscal policy to start lending a hand with some fiscal stimulus.
You would think that causing a second recession after the one following the GFC would have been a wake up call for European finance ministers to learn some macroeconomics. Yet what little learning there has been is not to make huge mistakes but only large ones: we should balance the budget when there is no crisis. more>
