New technology could reduce wind energy costs
Engineers from the University of Sheffield have developed a novel technique to predict when bearings inside wind turbines will fail which could make wind energy cheaper.
Selection of a desired dynamical behavior
Multi-stability, or coexistence of multiple behaviors, is a universal phenomenon found in almost all areas of science in nature, from lasers and chemical reactions to climate or the brain. The phenomenon of multi-stability ...
Two-ball bounce problem explained
Researchers from the University of Bristol have revisited a well-known classroom demonstration where a lighter ball is dropped on top of a larger heavier ball and offer a model to explain the phenomenon.
Our latest scientific research partner was a medieval bishop
There was something unusual about our recent research collaboration on the science of light, colours and the perception of rainbows: one member of the team wrote his best science in the 1220s.
Copying behavior in social groups may be governed by optimal control theory
Nature has provided herding animals and flocking birds with abilities to react to predator attacks and to sense risky features in their environment— like trees or cliffs—that might impede their defense. But how do these ...
New paper opens the door to the study of a new class of materials
A new paper by a team of researchers led by Karel Matous, College of Engineering Associate Professor of Computational Mechanics in the Department of Aerospace and Mechanical Engineering at the University of Notre Dame, describes ...
Flight and nuclear safety boosted by sound research
A system for using sound waves to spot potentially dangerous cracks in pipes, aircraft engines and nuclear power plants has been developed by a University of Strathclyde academic.
New study identifies key design features that boost violins' acoustic power
Some of the most prized violins in the world were crafted in the Italian workshops of Amati, Stradivari, and Guarneri—master violinmaking families from the 17th and 18th centuries who produced increasingly powerful instruments ...
To save your energy while strolling, walk this sway
When participants in a charity event took the first walk across the newly opened London Millennium Footbridge in 2000, their feet fell into sync, and the natural side-to-side motion of their steps caused the suspension bridge ...
