Researchers led by Arizona State University have completed some of the most sophisticated modeling of the effects of climate change and urban centers in the US, and are finding that some of today's proposed solutions will provide only a fraction of relief from the projected heat.
With energy demands rising, researchers at Penn State Behrend and the University of Tabriz, Iran, have completed an algorithm -- or approach -- to design more efficient wind farms, helping to generate more revenue for builders and more renewable energy for their customers.
Faced with the visual homogeneity of the interior of the Islamic mosque, the results obtained in the acoustic study allow us to confirm that the sound perception varies by area. This is due to the successive expansions that the temple has experienced during its history.
A new technique protects power grids from attacks against utility control systems that can shut down facility operations, trigger longer-term blackouts and even cause permanent physical damage.
A new building material developed at Empa is about to be launched on the market: 'memory-steel' can not only be used to reinforce new, but also existing concrete structures. When the material is heated (one-time), prestressing occurs automatically. The Empa spin-off re-fer AG is now presenting the material with shape memory in a series of lectures.
The fall of Angkor has long puzzled historians, archaeologists and scientists, but now a University of Sydney research team is one step closer to discovering what led to the city's demise -- and it comes with a warning for modern urban communities.
Sydney may soon undergo a transition from a monocentric city with sprawling suburbs radiating from one CBD, to a polycentric model -- one marked by several sub-centres -- according to a recent study led by a multidisciplinary team at the University of Sydney. Topics: Greater Sydney Commission, urbanisation, urban sprawl, complex systems, transport, residential, suburbs
For decades researchers have studied materials from structures to see why and how they fail. Before catastrophic failure, there are individual cracks or dislocations that form, which are signals that a structure may be weakening. While researchers have studied individual dislocations in the past, a team from the University of Illinois at Urbana-Champaign, the University of Tennessee, and Oak Ridge National Laboratory has made it possible to understand how dislocations organize and react at nanoscale.
Global sustainability is important now more than ever due to increasing urban populations and the resulting stress it can have on natural resources. But increased populations in cities may lead to greater efficiency, as a team of Penn State researchers discovered when they analyzed the water footprint of 65 mid- to large-sized US cities.
Rice University scientists enhance micron-sized titanium dioxide particles to trap and destroy BPA, a contaminant in water with health implications. The robust particles can be recharged for reuse in water remediation.
