Smart Building Responds to all Climate Conditions

A grid of sensors embedded into an innovative building insulation activates specific façade components to optimize energy savings while improving aesthetics. This high-tech kind of retrofitting approach uses several types of modules that allow real-time monitoring. The multifunctional modular façade system is able to adapt to a variety of climatic conditions.

Vibration Table Promises Different Ways of Testing

Vibration machines are crucial to test the forces that make things fall apart in the bumpy real world, from small components to complete systems like airplanes or nuclear weapons. Large, high-frequency vibration machines that shake things in several directions simultaneously are relatively new. Sandia National Laboratories has developed a large, high-frequency, 6-degrees-of-freedom (6DOF) vibration machine to qualify weapons components and revolutionize the way it does mechanical testing.

Measurements of Pluto’s Atmosphere Reveal Surprises

NASA's New Horizons probe performed the first-ever flyby of Pluto, zooming within 7,800 miles of its frigid surface. The close encounter is giving researchers their first up-close looks at Pluto, which has remained mysterious since its 1930 discovery.

Simulations Reveal Material with Record-Setting Melting Point

Using advanced computers and a computational technique to simulate physical processes at the atomic level, researchers at Brown University have predicted that a material made from hafnium, nitrogen, and carbon would have the highest known melting point: 4,400 kelvins (7,460 degrees Fahrenheit), about two-thirds the temperature at the surface of the sun.

Theory Turns into Reality for Nonlinear Optical Metamaterials

A research team has realized one of the long-standing theoretical predictions in nonlinear optical metamaterials: creation of a nonlinear material that has opposite refractive indices at the fundamental and harmonic frequencies of light. Such a material, which doesn’t exist naturally, had been predicted for nearly a decade.

Algorithm Magnifies Motions Indiscernible to the Naked Eye

MIT has been investigating techniques for amplifying movements captured by video, but indiscernible to the human eye. The algorithms can make the human pulse visible and even recover intelligible speech from the vibrations of objects filmed through soundproof glass. A new version of the algorithm can amplify small motions even when they’re contained within objects executing large motions. So, for instance, it could make visible the precise sequence of muscle contractions in the arms of a baseball player swinging the bat, or in the legs of a soccer player taking a corner kick.

Robots Learn to Observe, Adjust Their Force, and React


When robots and humans have to work together, it often leads to problems. Researchers on the CogIMon project want to teach robots to understand the forces during the movement of an object, and how to appropriately react to changes in weight or contact with the object while carrying it. Humans have no problem estimating the weight of an object, but robots lack this ability.
