He believes Duolingo will attract some portion of the estimated billion people who are interested in learning a new language, because unlike other good language-learning sites, Duolingo will be free.Working with PhD student Severin Hacker, for the past year and a half, the pair struggled with ideas on ways to convince millions of people to translate language text, for free, until hitting on the idea that it would have to be associated with something they’d want to do without prodding; in this case, learn a new language. And then, like Wikipedia, the results of the amateur’s translation process as they learned, would be honed as others worked on the same piece until the text reached some point of maturity, whereby it would be released to the web.Ahn claims the results of his crowd-sourced translation process creates text that is just as good as a professional service, which means that if history is any kind of gauge, sometime in the near future, when you use Google’s translation feature on a foreign language site, the results will likely be far superior to what you get currently when a machine does it for you.

(PhysOrg.com) — If you’re Google and you’re looking for the next crowd-sourcing piece to add to your already massive portfolio, it would seem Professor Luis von Ahn, of Carnegie Mellon, would be your man. After several previous successful ventures, Professor Ahn now believes he has a workable way to get millions of web users the world over to translate the Internet into every conceivable language, for free. The site, now sitting on the cusp of release, is to be called Duolingo, an appropriate name if ever there was one, for a site that will make creative use of people learning foreign languages by having them translate actual web content.

UCLA engineers create fully stretchable OLED

first_imgImage: Wiley (PhysOrg.com) — Engineers at the University of California, Los Angeles, have created the first fully stretchable organic light-emitting diode (OLED). The researchers devised a way of creating a carbon nanotube and polymer electrode and layering it onto a stretchable light-emitting plastic. Their device is a two-centimeter square with a one-centimeter square area that gives off a blue light. Details of their work were published in July in Advanced Materials. The paper is titled, “Intrinsically Stretchable Polymer Light-Emitting Devices Using Carbon Nanotube-Polymer Composite Electrodes.” This document is subject to copyright.

Citation: UCLA engineers create fully stretchable OLED (2011, August 27) retrieved 18 August 2019 from https://phys.org/news/2011-08-ucla-fully-stretchable-oled.html Researchers at UCLA demonstrate their fully stretchable OLED. They achieved the feat by sandwiching a carbon nanotube-polymer blend on either side of a light-emitting plastic. Another drawback encountered has been that the carbon nanotube film is rough and can cause shorting, says Zhenan Bao, a Stanford professor of chemical engineering who works on stretchable solar cells. “Using this method, they ended up with a relatively flat surface that can be used for an electrode.” Nonetheless, the need for further work in this area is far from over. She said that stretchable electronics demonstrated thus far lose conductivity after being stretched too far or too many times, so more research is needed. “We are still some ways off from having high-performance, really robust, intrinsically stretchable devices,” says Bao, but “with this work and those from others, we are getting closer and closer to realizing this kind of sophisticated and multifunctional electronic skin.”According to Technology Review, stretchable electronics could enter our worlds in the form of video displays that could be rolled up and tucked into a shirt pocket, or cell phones that could swell or shrink. In medical science, one might see electronic sheets draped like cloth.

These nanotubes are stretchable and are conductive, but to keep their shape, they need to be attached to some surface. Researchers have found that coating carbon nanotubes onto a plastic backing has not worked well, because the nanotubes slide off or past each other instead of stretching with the elastic. Until the UCLA team’s work, researchers were unable to come up with an entirely stretchable OLED.last_img read more

The content is provided for information purposes only. Hiriko consists of a Basque consortium of auto suppliers and engineers from MIT. The city car concept behind Hiriko was seeded at the MIT Media Lab and commercial development began years later in Basque country, by a Spanish consortium. Berlin has agreed on a pilot project with an initial phase this year, consisting of testing and adaptations for public use in Berlin. The official program is scheduled in 2014. The four wheels are able to rotate at a 60-degree angle. Factors playing into Deutsche Bahn’s decision to go with Hiriko as a car-sharing choice include the vehicle’s ability to fold and occupy little space, along with what is described as “vanguard” electronics that allow it to connect to intermobility platforms, according to Hiriko’s release. The car is powered by a lithium-ion battery pack that allows a range of 75 miles between charges. The Hiriko can be recharged in 15 minutes. In addition to the folding EV, dubbed The Fold, Hiriko plans an “ialai” roadster, which has been shown in Brussels. This is targeted for parks and tourist resorts. Another concept is a truck version called Laga. (Phys.org)—Deutsche Bahn, the company that operates the German railway network, will enlist the Hiriko electric vehicle as part of its transport network in Berlin. The Hiriko folding car, targeted for the city’s car sharing network, will undergo testing as a “last mile” step in Deutsche Bahn’s railway network. This means commuters will use the foldable car to get from station to their final destinations.

Hiriko is about eight feet long. For parking purposes, one can fold it down to five feet.The team behind Hiriko set out to pitch their vehicles to municipalities, to in turn rent them out to commuters as shared vehicles. Last year, there were reports that the Hiriko makers were proposing the use of their cars to urban centers such as San Francisco, Berlin and Barcelona, with prices at about $16,000 each.

A new coating material that could help reduce thermal noise on gravity

Citation: A new coating material that could help reduce thermal noise on gravity wave detector mirrors (2019, June 21) retrieved 18 August 2019 from https://phys.org/news/2019-06-coating-material-thermal-noise-gravity.html A team of researchers from the University of Glasgow, the University of Strathclyde and Hobart and William Smith Colleges has developed a new coating for mirrors used on gravity detectors that is 25 times less noisy than mirror surfaces used on LIGO. In their paper published in the journal Physical Review Letters, the group describes how they made it and how well it performed during testing. Electron diffraction pattern of the 600°C heat-treated silica-doped hafnia coating showing the coating to still be amorphous. This pattern is representative of those measured at lower heat-treatment temperatures. Credit: Physical Review Letters (2019). DOI: 10.1103/PhysRevLett.122.231102 The mirrors used in gravity wave detectors are positioned at the ends of its arms. Coherent light rays are reflected from both mirrors and interfere with each other. Gravitational waves are measured by noting how much the mirrors shift, resulting in slight changes in length of the arms to which they are attached, to an accuracy of 10–16 cm. As impressive as that is, researchers want to improve the sensitivity of the detectors used at LIGO/Virgo, even after the recent upgrade. To that end, members of the European Union have begun developing plans for the construction of what the Einstein Telescope, a gravitational wave detector with sensitivity 100 times higher than LIGO/Virgo. But for that to happen, improvements in the design of the current interferometer are required. One of those improvements is reducing the amount of thermal fluctuations in the mirror coatings. In this new effort, the researchers claim to have done just that.Fluctuations in the mirror coating are due to mechanical loss in which vibrations result in heat generation, causing thermal fluctuations. The noise from the fluctuations interferes with measuring the gravity waves. For the current systems, the level of noise is acceptable, but it must be reduced significantly for more sensitive detectors.To reduce the noise in the mirror coating, the researchers replaced the fused silica and tantalum oxide currently used with hafnium oxide and amorphous silicon, respectively. Testing showed the replacements to be 25 times less noisy than the present coatings—enough for use on the Einstein Telescope.Theorists have estimated that the Einstein Telescope should be capable of finding primary black holes and other exotic objects—and it should also provide the necessary findings to clarify the Hubble constant.

Fire breaks out at Park Streets Apeejay House

first_imgKolkata: A fire broke out at Apeejay House in Park Street around 11 am on Monday. Ten fire tenders were at the spot trying the douse the flames, which spread from the building’s server room in the fourth floor of the eight-storeyed building, reports said.Immediately security persons went towards the server room to check. By the time the fire was identified it had gone beyond control. Without wasting any time, the whole floor was vacated. Fire brigade and police personnel were called in. Six fire tenders were sent to douse the fire within few minutes. As the intensity of the fire grew, four more tenders were pressed into action. Sources informed that though sprinklers were activated at the right time, the fire could not be doused as its intensity was very high. Firefighters faced difficulties primarily as the flames occurred on the fourth floor. To deal with the situation a hydraulic ladder was used to reach the fire-affected area from outside. The fire-fighting management system of Apeejay House also helped the firefighters to douse the flames. Though the police informed that extent of damage is yet to be ascertained, sources informed that the damage will cost worth lakhs of rupees. The office premises have almost been turned into ashes. Around 1 pm, state Fire minister and Mayor Sovan Chatterjee visited the spot. Also Director General (DG) Fire, Jag Mohan, supervised the fire-fighting teams. The cause is yet to be ascertained. However, no one was hurt. After almost three hours, normal traffic movement resumed in Park Street.last_img read more
