Japanese scientists say giant plumes will prevent new Pangaea

first_img Explore further (PhysOrg.com) — For much of Earth’s history, the continents have shifted around, sometimes joining with others, sometimes tearing apart to form new continents. One such shift resulted in what Earth scientists call the Pangaea, or supercontinent, where nearly all of the land mass of Earth was consolidated into one single continent. Many Earth Scientists have predicted that such an event is likely to occur again over the next 250 million years or so. Yoshida and Madhava Santosh of Kochi University, Japan, disagree, if only slightly. They contend in their paper published in Terra Nova, that giant plumes far beneath the surface of the Earth will prevent South America and Antarctica from joining each other or the new continent. The plumes, or hot areas in the mantle some 2800 kilometers below the surface of the Earth, lying roughly between Africa and the South Pacific, are hot enough, the two researchers say, to prevent land masses settling over them. If they are right, the movement that is now going on, where Africa and Europe are moving towards one another, as are parts of Asia and Australia, would not result in the Pacific ocean being closed off as previous research has suggested. Instead, they say the Pacific Ocean will remain open with South America and Antarctica separate from the rest of the new super continent.While the origin of the plumes is really not very well understood (some suggest they are remnants of the primordial mantle) the heat they produce emanates up to the surface, raising its level in some cases as much as a kilometer or two. That is enough, most agree, to affect how plates move around relative to them. Until now, however, no one has thought to include the influence of these hot spots in models that seek to show how the continents will drift.Scientists are able to see how the continents have drifted in the past by studying the magnetic fields in old rock formations. They use this information, combined with the measurable movement of the continents today to come up with models that forecast what will happen in the distant future.For those that might wonder why such forecasts matter, it’s because it adds to the overall knowledge base that describes our one and only habitable planet. The more we as a people learn about how it works, the better able we will be not just survive on it, but to prosper as the uncertain future unfolds. © 2011 PhysOrg.com Temporal evolution of deformable continents.

Article first published online: 17 AUG 2011 DOI: 10.1111/j.1365-3121.2011.01018.xAbstractContinental masses were amalgamated, broken apart and reassembled within supercontinents during different times in Earth history. Here, we attempt to predict the configuration of a potential future supercontinent based on a numerical simulation model of mantle convection. The mantle convection in our model is driven by a density anomaly compiled from a global seismic tomography model. The temporal evolution of a highly viscous continent with an initial present-day configuration is simulated for over 250 Ma. The result reveals that Australia, Eurasia, North America and Africa would gather in the northern hemisphere to form the future supercontinent. On the other hand, Antarctica and South America remain in the present-day position even after 250 Ma from present, and do not join the future supercontinent amalgam. The configuration of the future supercontinent numerically simulated herein is broadly consistent with the hypothetical model of the future supercontinent Amasia speculated from geological correlations.

Google tries new approach with real time traffic estimates for Google Maps

The content is provided for information purposes only. Microsoft says Google is bypassing its cookie stopping technology too Explore further (PhysOrg.com) — It used to be when using Google Maps to plan your route, i.e. driving from one destination to another, Google Maps would also try to give you an estimate for how long it would really take you to make that trip using historical data trends it had built up over time. The problem was, real world travel times often varied greatly from the historical data, leaving drivers frustrated with the results. Because of that, Google finally pulled the plug on the feature altogether last summer. Now, it appears Google is ready to try again, though this time it’s taking a much different approach, using data generated in real time via third party reports and data it obtains via drivers who have phones running Android and who also choose to opt in to Google’s “My Location” feature by enabling it voluntarily on their phones. More information: Google’s blog: google-latlong.blogspot.com/20 … ration-based-on.htmlcenter_img © 2012 PhysOrg.com One of the nice features of Maps’ new real-time traffic monitoring is that users don’t have to go looking for it, the numbers show up automatically. Thus to use it, all a user does is click on the same links they always have, type in both departure and arrival destinations and Google will give both the average driving time in ideal conditions (in good weather with no other cars on the road) and what it believes to be the driving time based on current conditions. Obviously, there are some caveats. One is that in order for the whole thing to work, drivers must live in an area that Google has included, namely a major city. The other is that an awful lot of Android users must choose to opt in.For Google to make this announcement now, they must be confident that enough users are now already choosing to enable the “My Location” option. As for living in one of the cities that Google has included, it appears most of the larger ones in the United States are currently included as are several in Europe, most notably Great Britain. Google says it’s adding more as time passes, which carries a lot of weight coming from the company that has spent a veritable fortune building up images around the world for no better reason than to post them to its Street View feature.Because it’s based on real live user data, it’s likely Google’s new driving time estimates will be more accurate than in the past, and for the same reason, it’s likely those estimates will get better over time as more data points become available from Android users, which should hopefully outweigh any objections some might have over Google even having “My Location” as a feature on their phone which allows Google to not only collect GPS data on users, but to save that data and use it for other purposes.

Robot guards being tested in South Korea

first_img The robot, called Robo-Guard by many in the press, is equipped with several cameras, one of which is 3D, microphone, speaker and circuitry and software that allow it to roam autonomously in predefined areas within the prison. It also has software that allows it to analyze behavioral characteristics of inmates to help in deciding whether to alert the human guards. Its main purpose, according to the AFC, is to reduce manpower costs in prisons and to make a safer environment for both inmates and those that guard them.It also appears that the South Korean government, which has paid for the development of the robots, is using its prison population as a test ground for bolstering its robotics technology in general. After all, most, if not all of what these new robots do could just as easily be done by installing cameras in every hall and cell and connecting them to a computer that does the processing. But, because the testing is done in an environment where test subjects don’t have the option of objecting, research can be carried out that would not be possible in any other environment.

The content is provided for information purposes only. In addition to patrolling the halls, the robots are also able to serve as wireless two-way communications devices, allowing inmates and guards to communicate without the guard having to leave the command center. The human guards can also manually control the actions of the robots using an iPad application. The current test trial, which employs the use of three robots, is set to run for just one month and to cost a little over three quarters of a million dollars; at the end of which, researchers and politicians presumably will determine if the idea is feasible and whether the program ought to become permanent. If it does, the AFC has said they’d like to get the robots to one day perform body searches, though it’s not likely they would be capable of searching body cavities, instead they would perhaps be able to frisk inmates randomly, which likely would reduce the number of homemade weapons inmates use to harm one another or their guards. (Phys.org) — South Korea, a nation with a self-proclaimed goal of being a leader in robotics technology has, through the Asian Forum of Corrections (AFC), begun testing the feasibility of using robots as prison guards in an actual prison in Pohang. The robots’ duties, at least initially, are to patrol the halls between cells looking for signs of trouble, and if it finds it, alert the human guards who will take appropriate action.center_img © 2012 Phys.Org Robot guards to patrol South Korean prisons Citation: Robot guards being tested in South Korea (2012, April 18) retrieved 18 August 2019 from https://phys.org/news/2012-04-robot-south-korea.htmllast_img read more

Chip foundry has trouble meeting 28nm demand

TSMC reports shrinking profit, revenue in 3Q TSMC is the world’s largest contract chip maker, producing SoCs for chip vendor Qualcomm, Nvidia, and others. TSMC is also regarded as the world’s largest foundry and technological leader in 28nm chip production, but its 28nm yields are not high enough to satisfy demand.“Demand of 28-nanometer has surpassed our customers and our expectations, resulting in supply shortage. I think the worst of the supply shortage is behind us. We expect that we will be close to catching up in the fourth quarter this year. And we expect to have completely caught up with demand by the first quarter next year. And we will not fall behind again,” Morris Chang, CEO, told investors in April during a conference call.Chang blamed the shortage on the fact that demand of 28-nanometer surpassed both his customers and the company’s own expectations. “This supply shortage problem is not caused by new problems but by underestimates by both our customers and us, of the capacity and ramp-up speed required this year.”Qualcomm, a TSMC customer. must not only seek understanding but solutions for its business. (Qualcomm designs chips and blueprints are handed over to TSMC.) In March there was talk of how Qualcomm, unhappy about TSMC’s supply issues, was moving some of its business to GlobalFoundries and UMC. Qualcomm had warned in April that it will have trouble meeting demand for some of its advance cellphone chips for the rest of the year due to manufacturing constraints. However, earlier this month, Qualcomm said it expects advanced 28-nanometer chip supply to be under control towards the year-end. The Reuters report said that now Qualcomm was working with not only TSMC, but also “other foundries” to increase supply of the chips. Likewise, there are stories that other customers may be shopping around for competing foundries to address demand.Samsung has moved to get around the problem by investing in its own chip manufacturing line for mobile processors planned for completion by the end of next year. The company will spend $1.9 billion to build the plant to meet demand for chips powering mobile devices, according to Samsung. This is Samsung’s way of keeping control over the supply chain.

High demand for devices is trickling down to the fact that chip factories cannot keep up with demand. Especially rattling nerves has been news that Taiwan Semiconductor Manufacturing Company (TSMC) continues to report 28nm chip supply issues, which are expected to continue until the end of the year. Speaking at the annual general meeting, the TSMC chief said chip supplies will not be able to satisfy market demand until 2013. last_img read more

Ship will make its own waves for rig safety w Video

first_img“This concept provides an alternative to the semi-submersible platforms commonly used at present,” said Sverre Anders Alterskjær, a research scientist at the Norwegian Marine Technology Research Institute (MARINTEK). “The aim is to create a more mobile hotel unit which can be leased by oil companies which operate in several parts of the world. Our job has been to give the ship characteristics which make it more comfortable to live on at sea,” said Alterskjær, a research scientist. MARINTEK is a Norway-based marine simulation facility, which tested models of the new ship.The project, according to the SINTEF report, has a number of players; the ship was designed by a maritime design company SALT, under contract for Østensjø. Johannes Eldøy, a marine designer at SALT, said, “The most important thing has been to improve the efficiency and safety of the connection between the offshore installation and the gangway, which is as much as 55 meters long. This is a critical point because the vessel must display the least possible vertical motion in response to the waves while at the same time maintaining its position.”According to SINTEF, the integrated system designed to reduce rolling of the vessel was developed by Hoppe Marine and tested by Alterskjær and his research colleagues at MARINTEK. The ship is being constructed by Hyundai Heavy Industries in South Korea under contract for Østensjø. The ship is expected to be ready in 2015. © 2013 Phys.org Citation: Ship will make its own waves for rig safety (w/ Video) (2013, September 26) retrieved 18 August 2019 from https://phys.org/news/2013-09-ship-rig-safety-video.html More information: www.sintef.no/home/MARINTEK/Ne … hat-waves-wont-rock/ New asymmetric ice-breaker ship to clear larger path by moving at an angle The water is to be set in motion in opposing phase to the wave forces acting on the hull. According to the design, valve openings can be adjusted depending on the ship’s roll period; the motion of the water in the tanks is calibrated to match the strength of the waves on the sea. The ship will be equipped with azimuth thrusters (one definition of azimuth thrusters is an arrangement of propellers placed in pods that can rotate in any horizontal direction). According to a report on the project from SINTEF, the largest independent research organization in Scandinavia, the ship is equipped with six azimuth thrusters – “propeller drives with directional control used to keep the ship in the same position when in hotel mode.”The ship is 500 feet long; 800 workers can be accommodated with housing, gym, sauna, two pools, and office space. (Phys.org) —A so-called “hotel” ship to accommodate offshore oil rig workers is under construction, which will be engineered in a way to maintain its stability even over rough seas. The new Norwegian ship will make its own waves with internal water tanks. The effort is not only purposed for the comfort of the workers servicing the platforms but for safety. The design will support safe movement from the ship to the platform and precision work while over rough seas. How will this ship make its own waves? The answer is U-shaped water tanks integrated into the ship’s hull. The tanks will generate waves in such a way that can stabilize the vessel. This document is subject to copyright.

Rare contemporary art from Myanmar showcased in India

first_imgA rare group exhibition by five emerging artists, From Myanmar with Love, at the All India Fine Arts and Crafts Society (AIFACS) brought to the capital glimpses of new art practices and contemporary realities in modern Myanmar, coping with change. The participating artists include five leading names, Aung Myint, K Kyaw, Maung Aw, Than Kyaw Htay and Zaw Win Pe, who had exhibited solo at the Alliance Francaise in the capital in 2012.  Presented by the Calcutta Arts Club, a South Asian arts promotion platform, the exhibition is trying to raise awareness about contemporary art from Myanmar and build a buyers’ base in India, a growing market for art. Also Read – ‘Playing Jojo was emotionally exhausting’The fledgling democracy in Myanmar, which was ruled by a military junta for more than five decades, is yet to find an artistic idiom that showcases its socio-cultural character in all its diversity despite the variety of mediums the tribe of young artists is experimenting with, critics say.Technically, the new Myanmarese art is being described as superior to that of its smaller neighbours in Southeast Asia, critics say.Contemporary art from Myanmar, though not yet popular in India, is sought after in the Asian art capitals of Singapore, Hong Kong, Shanghai and across Europe and the US. Also Read – Leslie doing new comedy special with Netflix‘The artists who are exhibiting their works were recommended to me by galleries and collectors from Singapore and Europe. This exhibition will travel to at least six cities in India through the year,’ Calcutta Arts Club co-owner Abhishek Basu told.Last year, the Club had carried a showcase from Myanmar to five cities in Europe and this summer, the travelling exhibition is likely to go to London.‘Bookings for the works started even before the show was unveiled in the capital. I had posted an e-catalogue on the Internet,’ the promoter said. At a preview, Basu sold two of the paintings to local buyers, who elicited curiosity about contemporary art from Myanmar. The prices range from Rs 85,000 to Rs 6,40,000, Basu said, adding the artworks would be replenished as the show travels around the country.Myanmar has two major fine arts schools – the State School of Fine Arts in Yangon and in Mandalay under the National University of Arts and Culture.‘Younger artists experiment with mediums and practise at the art schools,’ Basu said. Most of the art traditions are still indigenous in nature outside the cities with Buddhist influences.last_img read more

If you’re not sleeping well, there are so many things you can try to fix the problem. First of all, stop reading your backlit screens before going to bed! In fact, just keep technology out of the bedroom all together. You also should limit your caffeine and other stimulants. Eating heavier in the morning and less at night can aid in better sleep. You have to experiment a little to find what works, but when you take care of yourself physically, in general, you’ll likely find that sleeping works just the way it should.I am working for last 6 years.
