Researchers from the University of Texas at Dallas developed a way to extract more power from the wind. The researchers used supercomputers at the Texas Advanced Computing Center to filter out the effects of turbulence and apply control algorithms that can better manage the operation of wind farms. The approach has the potential to increase wind power generation by 6-7 percent with a estimated increase in revenue of more than $600 million nationwide.
Using the photo-sharing site Instagram as a test case, Columbia researchers demonstrate how two common recommendation algorithms amplify a network effect known as homophily in which similar or like-minded people cluster together. They further show how algorithms turned loose on a network with homophily effectively make women less visible; they found that the women in their dataset, whose photos were slightly less likely to be 'liked' or commented on, became even less popular once recommendation algorithms were introduced.
Need stronger timber, better biofuels or new sources of green chemicals? A systems biology model developed over decades of research led by NC State University will accelerate progress in engineering trees for specific needs.
New Stanford research shows that, over the past century, linguistic changes in gender and ethnic stereotypes correlated with major social movements and demographic changes in the US Census data.
Interruptions in workflow, such as a phone call while working on another task, or when a colleague stops by for a chat, can lead to inefficiencies in the workplace. Now, a study from the University of Missouri has determined that workflow interruptions are most likely to occur during two key events -- electronic medical record documentation and direct patient care. Findings suggest that changes in workflow in emergency departments could increase the care team's efficiency and help improve patient care.
An international research team has proposed a way to increase the efficiency of wireless power transfer over long distances and tested it with numerical simulations and experiments. To achieve this, they beamed power between two antennas, one of which was excited with a back-propagating signal of specific amplitude and phase. The new development will improve wireless power transmission. This study also offers new approaches to wireless communication, where external conditions can change unpredictably.
The flight routes of passenger aircraft are generally well established. In practice, unforeseen factors, mainly related to the weather, often force pilots to cover more kilometers than anticipated. A Polish-Colombian team of scientists and engineers, inspired by the behavior of insects and birds, has developed software that allows real-time rational modification of flight routes. As a result, it was possible to achieve measurable savings, both financial and with regard to environmental protection.
Scientists from Nanyang Technological University, Singapore, have developed a robot that can autonomously assemble IKEA's Stefan chair in 8 minutes and 55 seconds.
A new mathematical model can predict the effectiveness of microbiome therapies that manipulate the immune system through live bacteria and could help doctors choose the most appropriate treatment for people with inflammatory or allergic diseases, a study in eLife reveals.
Some Illinois researchers working on artificial muscles are seeing results even the fittest individuals would envy, designing muscles capable of lifting up to 12,600 times their own weight. Assistant professor of mechanical science and engineering Sameh Tawfick, Beckman postdoctoral fellow Caterina Lamuta, and Simon Messelot recently published a study on how to design super strong artificial muscles in the journal Smart Material and Structures. The new muscles are made from carbon fiber-reinforced siloxane rubber and have a coiled geometry.
