It was a result so unexpected that Massachusetts Institute of Technology researchers initially thought it must be a mistake: Under certain conditions, putting a cracked piece of metal under tension has the reverse effect, causing the crack to close and its edges to fuse together. The surprising finding could lead to self-healing materials that repair incipient damage before it has a chance to spread.
FluxMerge, adjusts the magnetic reluctance distribution across the pole faces opposite the airgap. The magnetic flux crossing over the airgap, as a result, merges toward the central axis along the magnetic circuit path to reduce leakage into the surrounding space. Reduced airgap leakage improves efficiency by about 1.5%, and offers the opportunity for more compact designs.
Product development firm Cambridge Consultants is helping conservationists protect some of the world’s most rare and endangered species. As part of the Instant Wild project, new satellite-connected and motion-triggered cameras are beaming near-real-time images of animals from the remotest areas of Africa. A mobile app allows users anywhere in the world to view the photos, providing early warning of illegal poaching activity.
On Thursday, Virgin Galactic demonstrated the SpaceShipTwo’s full technical mission profile in a single flight for the first time. The second rocket-powered, supersonic flight of its passenger carrying reusable space vehicle marked the first high altitude deployment of the unique wing “feathering” re-entry mechanism and achieved the highest altitude and greatest speed to date.
Ion chromatography (IC) is an analytical technique for the separation and determination of anionic and cationic analytes in various sample matrices. By introducing a high-pressure reagent-free IC system that successfully integrates conductive, electrochemical and charge detection, Thermo Fisher Scientific Inc. has brought a new level of performance and speed to this important separations process.
Curiosity Rover team members re-live the dramatic Aug. 6, 2012 landing and the mission's achievements to date in a recent event aired on NASA Television and the agency's website. In the year since inspiring millions of people worldwide with its one-of-a-kind landing in a crater on the Red Planet, Curiosity has achieved its primary scientific objective; finding evidence that ancient Mars could have sustained microbial life.
For decades, teams of Berkeley Lab scientists have investigated the ways that indoor air quality affects human health. In Berkeley Lab's test kitchen scientist Brett Singer and his team are measuring the pollutants emitted by cooking foods and evaluating how effective various range hoods are in capturing the pollutants.
In this video, Tim Samaras from the National Geographic Channel Storm Chasers talks about his passion for chasing and studying storm systems. He explains how he used National Instruments’ (NI) LabVIEW and CompactDAQ in a new instrument that is deployed on the ground in front of a tornado. After the storm he uses another NI application, DIAdem, to view the data that was collected.
Laboratory water purification specialists for more than 75 years, ELGA provides complete water purification solutions for new and refurbished laboratories. ELGA has recently released a new set of videos that describe both the company’s expertise in delivering labwater solutions, and the many options for configuring these solutions for the laboratory.
Electron beam freeform fabrication (EBF3) is a layer-additive process that uses an electron beam and wire to fabricate metallic structures. The process efficiencies of the electron beam and the solid wire feedstock make the EBF3 process attractive for use in-space.
ITER research and development projects.
Medical records, texts, journals and research documents are all written in natural language -- a language that computers traditionally struggle to understand. The ability to deliver a single, precise answer from these documents could go a long way in transforming the healthcare industry....
On February 14, 2011, Watson, the IBM computing system designed to play Jeopardy!, faces its toughest challenge yet. Jeopardy! The IBM Challenge pits the two greatest champions in the show's history against a machine that rivals their ability to deliver a single, precise answer to a Jeopardy! clue.
Enormous amounts of data are generated every day in the financial industry. The deep analytics of Watson, the IBM computer system designed to play Jeopardy!, could have profound effects on how companies make use of this information.
The customer service industry is judged on two criteria: speed and accuracy. Watson, the IBM computing system designed to compete on Jeopardy!, is built to achieve both of these. IBM experts share their thoughts on how the DeepQA technology that powers Watson could transform the customer...
