© 2012 PhysOrg.com At tech events, wearable displays that have showcased in the form of high-tech visors and chunky spectacles or goggles seem to draw measured responses—impressive inventions for private media viewing at home or on the go but silly-looking or even evocative of special-recovery shades for postoperative elderly outpatients. We noticed at least one reference to “grandma glasses.” Epson’s Moverio BT-100 Wearable Display do not look exactly like designer sunglasses but they do have loaded features for gadget collectors who do not think $699.99 is an unthinkable price. Explore further Epson packs features into new Android HMD More information: www.epson.com/cgi-bin/Store/jsp/Moverio/Home.do According to reports, the glasses have pico projectors that are able to create a virtual experience of up to 80 inches’ display at a perceived distance of about 16 feet. According to Expert Reviews, the headset has a tiny pico projector built into each arm, pointing inwards towards an angled mirror in each lens, which projects the image in the center of the wearer’s vision. The dark outer visor is semi-transparent, letting the wearer see surroundings without being distracted by them. The device carries 1GB of built-in storage. Users access downloaded content via the microSDHC card slot (4GB card included) There is built-in WFi connectivity; a lithium rechargeable battery provides around six hours of continuous use. Built-in earbuds provide Dolby Mobile virtual surround sound. Of all the features, much appears to be made of the Android name in Epson product descriptions, as “Android-powered Moverio glasses.” The glasses connect to a control module; this Android 2.2-based handheld device lets the user select the content to view. Moverio is running on an Android 2.2 platform with Adobe Flash support. Epson publishes the kernel and an SDK, but the company is requiring developers to submit apps to them for consideration rather than going through an app store. The good news is that Epson is interested in seeing more new Android-based applications and side-by-side 3D content for its Moverio BT-100. To help support application and content development for Moverio BT-100, Epson is offering programs for developers residing in the United States.Meanwhile, Epson’s end-user vision is to see the product adopted not merely for personal entertainment use but also for business and professional ends. Epson America’s Anna Jen, director of New Business Development, said the Moverio BT-100 may play a role in virtual training platforms, 3D-CAD environments, and visualizing 3-D design renderings.

Transformation of the Electric Sector (Phys.org) — In the United States, renewable energy sources could supply 80 percent of electricity demand in 2050 just by using technologies commercially available today. That is the word from a new report from the National Renewable Energy Laboratory, Renewable Electricity Futures Study (RE Futures). The report offers a detailed focus on the extent to which U.S. electricity needs can be supplied by renewable energy sources, including biomass, geothermal, hydropower, solar, and wind.

Explore further More information: www.nrel.gov/analysis/re_futures/ Renewable energy costs falling: agency The lineup of renewable electricity technologies is discussed from a national perspective. The study’s overall position is that a future U.S. electricity system largely powered by renewable sources is possible and that further work is warranted to investigate “this clean generation pathway.“Reaching an 80 percent-renewables goal by 2050, says the study, will involve fifty percent of electricity coming from wind and photovoltaics. “The analysis treats a variety of scenarios with prescribed levels of renewable electricity generation in 2050, from 30% to 90%, with a focus on 80% (with nearly 50% from variable wind and solar photovoltaic generation).” A diverse mix of renewable energy resources, such as geothermal, solar, wind and wave energy, can support multiple combinations of renewable technologies. The results would be meaningful reductions in electric sector greenhouse gas emissions and water use. The study finds no geographical gaps in achieving the 2050 goal. “All regions of the United States could contribute substantial renewable electricity supply in 2050, consistent with their local renewable resource base.”Hydropower is the biggest renewable contributor, but hydropower plays less of a role over the next few decades. NREL suggests a growing role for offshore wind. NREL also says dedicated biomass power plants, as opposed to just feeding biomass to coal plants, are needed.The study is significant as the most comprehensive analysis of high-penetration renewable electricity of the United States to date. IEEE Spectrum comments that the study may also impact debates over renewable and their future. “The fossil fuel supporters who claim coal and natural gas will always be required to provide baseload power are standing on shakier ground all the time.”The study maintains that reaching the 80 percent goal is not insurmountable, but only if the right changes are made.”While this analysis suggests such a high renewable generation future is possible, a transformation of the electricity system would need to occur to make this future a reality. This transformation, involving every element of the grid, from system planning through operation, would need to ensure adequate planning and operating reserves, increased flexibility of the electric system, and expanded multi-state transmission infrastructure, and would likely rely on the development and adoption of technology advances, new operating procedures, evolved business models, and new market rules.” Citation: Renewables can fill 80 percent electricity demand in U.S. in 2050 (2012, June 20) retrieved 18 August 2019 from https://phys.org/news/2012-06-renewables-percent-electricity-demand.html © 2012 Phys.Org

Hot spots are plumes of hot material that rise from deep within the Earth—sometimes, when encountering thin crust, they burst through forming volcanoes such as that which occurred with the Pacific Plate causing the formation of the Hawaiian Islands. Scientists believe that while tectonic plates move around, hot spots do not. Thus, plates sometimes move over the top of a hot spot. In the case of North America, the researchers believe that as the tectonic plate shifted to the west, its underside was burned from below by a hot spot—like a dinner plate passing over a candle. So great was the movement, it left the hot spot hiding beneath the Atlantic Ocean, where it persists to this day.To come to these conclusions, the researchers studied data from the earthquake that occurred back in 2011, centered in Virginia. Because seismic waves travel slower when moving through warmer rock, the researchers were able to discern that there lies a ridge of warm rock beneath the North American tectonic plate—evidence they say of burning left behind by the hot spot, as its depth is roughly equal to the depth of the bottom of the plate. The research data indicates that the scaring reaches from Missouri in the west towards Virginia in the east, then north-east through Maryland, Pennsylvania, New York and Massachusetts before appearing on the underside of the crust below the Atlantic Ocean.Prior research by other scientists has suggested that when a tectonic plate passes over a hot spot, and can’t burst through, the result is oftentimes diamond-bearing formations. In addition to studying seismic waves, the researchers also noted that there is a diamond-bearing formation over one part of the scarred segment—in Kentucky—further proof they say, that their assumptions about the hot spot are correct. More information: Hidden hotspot track beneath the eastern United States, Nature Geoscience (2013) DOI: 10.1038/ngeo1949AbstractHotspot tracks are thought to be the surface expressions of tectonic plates moving over upwelling mantle plumes, and are characterized by volcanic activity that is age progressive. At present, most hotspot tracks are observed on oceanic or thin continental lithosphere. For old, thick continental lithosphere, such as the eastern United States, hotspot tracks are mainly inferred from sporadic diamondiferous kimberlites putatively sourced from the deep mantle. Here we use seismic waveforms initiated by the 2011 Mw 5.6 Virginia earthquake, recorded by the seismic observation network USArray, to analyse the structure of the continental lithosphere in the eastern United States. We identify an unexpected linear seismic anomaly in the lower lithosphere that has both a reduced P-wave velocity and high attenuation, and which we interpret as a hotspot track. The anomaly extends eastwards, from Missouri to Virginia, cross-cutting the New Madrid rift system, and then bends northwards. It has no clear relationship with the surface geology, but crosses a 75-million-year-old kimberlite in Kentucky. We use geodynamical modelling to show that an upwelling thermal mantle plume that interacts with the base of continental lithosphere can produce the observed seismic anomaly. We suggest that the hotspot track could be responsible for late Mesozoic reactivation of the New Madrid rift system and seismicity of the eastern United States.

(Phys.org) —Well known hacker Samy Kamkar has figured out a way to program a store-bought drone to take away control of other store-bought drones from their owners, and then to give the enslaved drones commands of its own. He calls the result SkyJack. Even more dramatically, he’s created a video describing how to do it so that others can create their own drone hackers, and has posted it all on his blog. Citation: Hacker modifies toy drone to hack and take over other toy drones (2013, December 5) retrieved 18 August 2019 from https://phys.org/news/2013-12-hacker-toy-drone-hack-drones.html Samy Kamkar achieved fame by knocking MySpace offline in 2005 (and going to jail for it). After going straight, he was one of those people instrumental in exposing phone makers that were adding tracking capabilities to smartphones. In this latest endeavor, he’s added off-the-shelf hardware and Internet available code to a commercially sold drone—the quadcopter Parrot—to allow it to hack other Parrot drones.The concept is rather simple, he added a small single board computer (Raspberry Pi circuit board) that runs Linux, to his Parrot, installed some code and then added a little battery and two tiny wireless transmitters. Once airborne, the drone listens for a Wifi signal, if it hears one, it looks for a MAC address from a list it has, if a match is found, the device sends a disabling code, revoking control from the drone’s owner. Then his drone pretends it’s the rightful owner and starts sending control codes to the enslaved Parrot, directing its flight, and/or sending back images from its camera. More than anything, the SkyJack appears to be a stunt of sorts, coming on the heels of an announcement by Amazon that it plans to deliver packages via drones someday soon. The makers of Parrot will obviously be embarrassed by Kamkar ‘s work, but will undoubtedly add security features to them, preventing them from being skyjacked, which they probably should have done before selling them in the first place. His actions do however, highlight the increasing presence of drones in our lives and how those that make them need to be sure that they can’t be hacked, lest pizza’s or mail order socks in the future be delivered to the wrong address, or worse, fall prey to those wishing to create a fleet of enslaved roaming drones darkening our skies with menace. © 2013 Phys.org This document is subject to copyright.

Explore further What created this huge crater in Siberia? © 2014 Phys.org Last month reindeer herders in the Yamal Peninsula in Siberia came across a mysterious hole in the ground—after reporting what they’d discovered, a helicopter was dispatched and personnel aboard took snapshots of what was found. The photos have since gone viral on the Internet generating speculation about what caused the hole to come about—some suggested it was nothing more than a meteor crater or sinkhole, others seemed convinced it was part of an alien invasion, while others yet postulated that it was probably the remains of a collapsed pingo (a mound of earth covered ice). Now, after visiting the site of the first hole discovered, a team of researchers has concluded that the hole, and others like it that have been spotted, are most likely due to a sudden release of methane as permafrost melts. They note Siberia has experienced extremely warm summers the past two years.After sending a sensor down into the hole the researchers found an unusually high concentration of methane—9.6 percent, as compared to the normal 0.000179 percent. That finding and the fact that mounds of dirt near the mouth of hole indicate a blast of some sort occurred, has the researchers convinced that the warm summers caused permafrost melting which released underground methane. Gas pressure, they believe, built up to a tipping point, then was suddenly released, pushing out the material that had been sitting on top of it. Oddly, the depth of the hole is still not known. The researchers lowered a camera, but the line used was not long enough to allow for reaching the water (likely from melting permafrost) at the bottom. They estimate the depth to the water is approximately 70 meters. They would not even venture a guess as to the depth of the hole below the water.The researchers plan a return visit to the hole to conduct more research but aren’t confident of what they will find—they note that the walls are already collapsing and water movement can be heard, suggesting that whatever evidence exists now, might be gone by the time they return. This frame grab made Wednesday, July 16, 2014, shows a crater, discovered recently in the Yamal Peninsula, in Yamalo-Nenets Autonomous Okrug, Russia. Russian scientists said Thursday July 17, 2014 that they believe the 60-meter wide crater, discovered recently in far northern Siberia, could be the result of changing temperatures in the region. Andrei Plekhanov, a senior researcher at the Scientific Research Center of the Arctic, traveled on Wednesday to the crater. Plekhanov said 80 percent of the crater appeared to be made up of ice and that there were no traces of an explosion, eliminating the possibility that a meteorite had struck the region.

Ritu Gupta’s solo exhibition Empowering Love opens at the Open Palm Court of the India Habitat Center on the 1 July 2013. Beginning as a self-taught artist, Ritu’s development as an artist has been possible purely because of her passion to paint, decorate, explore and express. Her paintings demonstrate the influence of the traditional art and culture in a style that is very much her own. One has to note that the stream of Indian culture paintings and its message can largely traceable in her paintings. Though the works are her way to explore and understand Indian tradition, they begin to reflect the artists understanding of childhood, masculinity, femininity, union and desire. Also Read – ‘Playing Jojo was emotionally exhausting’The current series of works is called Empowering Love, the journey is no longer sharp and steep. One can see the artist settling down into an understanding of human form heavily inspired by the supple slenderness seen in the medieval Indian styles ranging from Chola bronzes, to Kangra paintings. However a key feature to note is that the artist does not seem to be making a school or style centric adaptation. Instead one is reminded of the early 20th century Bengal revivalists and their understanding of an authentic (traditional) Indian form in terms of being soft, supple and feminine (as against the hard(er) masculine European understanding of human body. This series is devoted to the romantic (divine) love of Radha and Krishna, which in no way is explicitly referred to in iconographic terms. The reference is implicit and subtle. Also Read – Leslie doing new comedy special with NetflixThe artist does away with traditional iconography and instead chooses to focus on the mood of lovers. This series is has very close references to the late Guler and Kangra school not so much in treatment of foliage, moonlight and the romantic mood. Yet again, she makes traditional narrative her own and by now begins to show a certain mastery over the understanding of the human body in compositional and design terms. Her urge to play and appropriate takes over again and she focuses of backgrounds, detailing and decorative motifs. WHEN: 1 to 7 July, 11 am- 8 pm WHERE: Open Palm Court, India Habitat Center
The eleven-week show, The Body in Indian Art has entered into its last week and is slated to conclude on 7 June. The exhibition has broken quite a few conventions and notions in the field of museology besides having lent a novel perspective to the way the body has been depicted in India over the millennia.Curated by art historian Naman P Ahuja, the show has pooled in 365 objects in total from 44 museums, private collectors and artistes themselves, making it the longest-ever line-up of exhibitors at an Indian show in any museum. Also Read – ‘Playing Jojo was emotionally exhausting’Displayed at the exhibition are a few tiny Harappan figures, a monumental Naga Deva, an 8th-century Uma-Maheshvara and a marble tomb of a Mughal lady among others which are being shown for the first time as part of the exhibition. Neil MacGregor, director of the british Museum said, ‘The age-old inclusiveness of Indian culture is second to none globally and a landmark exhibition currently on in the country’s capital mirrors its range and depth. ‘It is a broad spectrum of aesthetics in the representation of the human body, exemplifies the harmonious coexistence of religions in the subcontinent over the past four millennia’, he added. The show has a lot more to offer. If you have not been there yet, it’s the time to head on.
I was once startled to see a beautiful Jamini Roy painting at the entrance of industrialist and veteran art collector B K Birla’s house. He and his wife, wonderful hosts, told me that many years ago they had picked up the piece for a paltry Rs 100 on a Sunday morning walk to the artist’s studio in the vicinity. Decades have flown by till art collector and restorer Ganesh Pratap Singh decided to give us a glimpse into Jamini Roy’s works and life through a documentary titled, The Art of Jamini Roy. The occasion: 125 years of the artist’s birth. Also Read – ‘Playing Jojo was emotionally exhausting’Singh, who based his documentary on 300 odd letters written by the artist and about 1000 odd archival material, now plans to show the film on Roy at art museums across the world which have a Jamini Roy collection like the Philadelphia museum of Art. This has already been shown at Max Mueller Bhavan, Gorky Sadan, Christie’s and IIC, Delhi. Directed by the artist’s grandson Debabrata Roy, Singh and his team made trips to Roy’s ancestral home in Beliatore in the Birbhum district to discover the artist’s roots. Also Read – Leslie doing new comedy special with Netflix‘Roy painted ordinary men and women from the village, scenes from the Krishnalila, often reinventing popular images from the patua’s repertoire. He broke with many traditions of his time’, Singh told Millennium Post. The letters were written by Roy to John Irwin, Bishnu Dey, Tarashankar Bandopadhyay, Hemen Mazumdar and Stella Kamrisch.As this 53 minute documentary unfolds the author’s life, it becomes apparent that Roy pulled away from the Impressionistic art trending at the time. Sent to study at the Government School of Art in Calcutta, he was taught to paint classical nudes in oil but he soon realised that he needed to draw inspiration from Bengal’s own folk and tribal art for inspiration. The Kalighat Pat, with its bold sweeping brush-strokes, also influenced his style. Roy’s idiom was a reaction against the Bengal school and the western tradition.Singh collected his material from two sources, Roy’s family and collectors of the 50s, like Bishnu Dey, Satsh Sinha, Hemen Mazumder and Atul Bose. Army officers who were posted in the North East in those years after the World War, often picked up Roy’s paintings for a song. Now, Roy’s originals fetch in the region of Rs 5 lakh to Rs 20 lakh a piece.Roy was awarded the Padma Bhusan in 1955. His work can be found in many private and public collections such as the Victoria and Albert Museum, London. Singh, who also owns quite a few Roy paintings himself, now wants to write a book on him, using the letters, photographs, clippings and other archival material at his disposal.
Seven Mexican soldiers being held in the June killings of 22 suspected criminals will be tried by a civilian judge, three of them for homicide, federal justice officials said Sunday.The troops were ordered arrested Friday by a Mexico state judge for dereliction of duty in the June 30 incident.Three of them are charged with aggravated homicide, and one of them with allowing a crime to take place. For now, the soldiers are jailed in a military detention center. In September, a witness said the gun battle itself had left only one dead, and the other 21 were killed in cold blood by the soldiers — including her 15-year-old daughter.The case adds to the shock surrounding a more recent case of 43 students who went missing in the southern town of Iguala in late September. They were allegedly taken away and killed by police linked to a drug cartel.If confirmed, the incident would mark one of the worst horrors in a drug war that has left more than 80,000 people dead since the conflict ramped up in 2006.
Slamming the NDA government on fishermen issue, BJP ally MDMK on Tuesday said it is ‘playing with the lives of Indian fishermen’ and its UPA-like approach towards Sri Lanka had emboldened Colombo to treat them (fishermen) with disdain. Alleging that Modi government was ‘playing’ with the lives of Indian fishermen, MDMK founder Vaiko said, ‘I ask the Modi government…why are you insisting with defence ties with Sri Lanka even after this…the lives of Tamil fishermen should not be taken lightly. Also Read – Need to understand why law graduate’s natural choice is not legal profession: CJIIf the NDA follows the UPA policy on Sri Lanka, the Tamil youth will not tolerate that.’The statement comes in the backdrop of five Indian fishermen being awarded death penalty by a Sri Lankan court for drug-trafficking last week.Slamming the centre on ties with Colombo, from inviting its president Mahinda Rajapaksa for Modi’s swearing-in to the continued defence ties, Vaiko said despite these, Chinese naval ships had recently berthed in Sri Lankan waters, which he said was a direct threat for Tamil Nadu. Also Read – Health remains key challenge in India’s development: Kovind‘Such an approach by the Modi government towards Sri Lanka was a reason for the five fishermen being awarded death penalty as Rajapaksa controlled his country’s judiciary,’ he told reporters after spearheading a protest here against the court verdict.He warned that the centre may have to face the consequences of such an approach towards Sri Lanka. Vaiko had been critical of UPA government’s ‘friendly’ relations with Sri Lanka, including maintaining defence ties, and had accused it of aiding Colombo in its pursuit against the rebel LTTE, with the last leg of hostilities in 2009 witnessing heavy civilian casualties when Rajapaksa was president.
