Kinetica Dynamics: Skyscraper stabilizer

Kinetica Dynamics may be a young start-up, but its approach to stabilizing tall buildings is based on a well-established idea.“It’s a reinvigoration of an old vibration damping technology,” says Michael Montgomery, an engineer and the company’s co-founder and chief executive.

The technology, a polymer that diminishes vibration and shock, is bonded tightly to the structure of buildings and was first used in the twin towers of New York’s World Trade Center to prevent motion sickness caused by the upper parts of the towers moving in the wind. The polymer, which was created by the US technology company 3M, was installed between the steel frames throughout the towers to dissipate vibrations. Read more in Nature.

SSIMWave: Seeing the screen

“We want to become synonymous with good user experience for video,” says Abdul Rehman, co-founder and chief executive of SSIMWave. The start-up, which was spun out of the University of Waterloo in Canada in 2013, wants to improve how people watch videos online.

The company’s technology is based on a family of algorithms developed by Zhou Wang, a computer engineer at Waterloo and Rehman’s PhD supervisor. The structural similarity, or SSIM, algorithms can predict how someone will perceive the technical quality of a video, and thus help to ensure that viewers have the best possible experience. Read more in Nature.
