The Role of Hand Loom Industry

The Role of Hand Loom Industry

The introduction of frame looms and stand looms is a classic example of this. These were introduced two decades ago as alternatives to pit looms but both have yielded poor results due to technical problems. There was never an assessment of the difficulties faced by the weaver in adapting to the new looms. The failure only added more baggage to the travails of the hand loom weaver, who continues to be characterized as backward and resistant to change. It is safe to conclude that the new move of changing the ‘definition of hand loom’ is not directed at helping the hand loom weaver, but at bringing the power loom into the orbit of hand looms. - Read More

Transmit Brain to Brain Knowledge transfer

The Internet was a way to connect computers, and now it can be a way to connect brains, Stocco said. We want to take the knowledge of a brain and transmit it directly from brain to brain.

Rajesh Rao, a University of Washington professor of computer science and engineering, has been working on brain-computer interfacing (BCI) in his lab for more than 10 years and just published a textbook on the subject. In 2011, spurred by the rapid advances in BCI technology, he believed he could demonstrate the concept of human brain-to-brain interfacing. So he partnered with Stocco, a UW research assistant professor in psychology at the UW's Institute for Learning & Brain Sciences.
On Aug. 12, Rao sat in his lab wearing a cap with electrodes hooked up to an electroencephalography machine, which reads electrical activity in the brain. Stocco was in his lab across campus wearing a purple swim cap marked with the stimulation site for the transcranial magnetic stimulation coil that was placed directly over his left motor cortex, which controls hand movement.
The team had a Skype connection set up so the two labs could coordinate, though neither Rao nor Stocco could see the Skype screens.
Rao looked at a computer screen and played a simple video game with his mind. When he was supposed to fire a cannon at a target, he imagined moving his right hand (being careful not to actually move his hand), causing a cursor to hit the "fire" button. Almost instantaneously, Stocco, who wore noise-canceling earbuds and wasn't looking at a computer screen, involuntarily moved his right index finger to push the space bar on the keyboard in front of him, as if firing the cannon. Stocco compared the feeling of his hand moving involuntarily to that of a nervous tic.
"It was both exciting and eerie to watch an imagined action from my brain get translated into actual action by another brain," Rao said. "This was basically a one-way flow of information from my brain to his. The next step is having a more equitable two-way conversation directly between the two brains."
The technologies used by the researchers for recording and stimulating the brain are both well-known. Electroencephalography, or EEG, is routinely used by clinicians and researchers to record brain activity noninvasively from the scalp. Transcranial magnetic stimulation, or TMS, is a noninvasive way of delivering stimulation to the brain to elicit a response. Its effect depends on where the coil is placed; in this case, it was placed directly over the brain region that controls a person's right hand. By activating these neurons, the stimulation convinced the brain that it needed to move the right hand.
Computer science and engineering undergraduates Matthew Bryan, Bryan Djunaedi, Joseph Wu and Alex Dadgar, along with bioengineering graduate student Dev Sarma, wrote the computer code for the project, translating Rao's brain signals into a command for Stocco's brain.
"Brain-computer interface is something people have been talking about for a long, long time," said Chantel Prat, assistant professor in psychology at the UW's Institute for Learning & Brain Sciences, and Stocco's wife and research partner who helped conduct the experiment. "We plugged a brain into the most complex computer anyone has ever studied, and that is another brain."
At first blush, this breakthrough brings to mind all kinds of science fiction scenarios. Stocco jokingly referred to it as a "Vulcan mind meld." But Rao cautioned this technology only reads certain kinds of simple brain signals, not a person's thoughts. And it doesn't give anyone the ability to control your actions against your will.
Both researchers were in the lab wearing highly specialized equipment and under ideal conditions. They also had to obtain and follow a stringent set of international human-subject testing rules to conduct the demonstration.
"I think some people will be unnerved by this because they will overestimate the technology," Prat said. "There's no possible way the technology that we have could be used on a person unknowingly or without their willing participation."
Stocco said years from now the technology could be used, for example, by someone on the ground to help a flight attendant or passenger land an airplane if the pilot becomes incapacitated. Or a person with disabilities could communicate his or her wish, say, for food or water. The brain signals from one person to another would work even if they didn't speak the same language.
Rao and Stocco next plan to conduct an experiment that would transmit more complex information from one brain to the other. If that works, they then will conduct the experiment on a larger pool of subjects.
Their research was funded in part by the National Science Foundation's Engineering Research Center for Sensorimotor Neural Engineering at the UW, the U.S. Army Research Office and the National Institutes of Health.

Road Map 2050

Back Casting

A back-casting approach can help to highlight where momentum must be broken and re-directed in order to achieve future objectives, while forecasting tends to extend current trends out into the future to see where they might arrive. The work on the three volumes of the Roadmap 2050 project has been undertaken by:

Volume I: Technical and Economic Analysis: McKinsey & Company

Volume II: Policy Report: E3G; The Energy Research Centre of the Netherlands

Volume III: Graphic Narrative: The Office for Metropolitan Architecture

Discussion with Global Think Tanks

TBD 


Mind Algorithm: Radboud University Netherlands


Mind reading

A team from Radboud University Nijmegen in the Netherlands was able to extract information from the human brain by applying a combination of high-resolution MRI, shape recognition software and computational modeling. 

The scientists were able to create a database of the specific changes that happened in the brain after each letter appeared on screen, which was run through an algorithm designed to work in a similar way as the brain when it builds images of objects from the sensory information it receives.

Hindu encyclopedia culmination of a 25-year academic effort

Hindu encyclopedia culmination of a 25-year academic effort

COLUMBIA, S.C. — A comprehensive encyclopedia of one of the world’s major religions is set to be unveiled next week in South Carolina. The 11-volume work covers Hindu spiritual beliefs, practices and philosophy, and is the culmination of a 25-year academic effort.




The encyclopedia is written in English and includes about 7,000 articles on Hinduism and its practices. The work also deals with Indian history, languages, art, music, dance, architecture, medicine, and women’s issues.


The first volumes arrived at the University of South Carolina on Wednesday. They are to be donated to the university’s library system.

USC Professor Hal French is associate editor of the “Encyclopedia of Hinduism” and says the goal was to have a definitive work. He calls the effort a milestone of research that brought Eastern and Western scholarship together.

"This hadn't really been attempted before," said French, 83, a distinguished professor emeritus of religious studies at the school and an associate editor. "It is a milestone of research that brought together both Eastern and Western scholarship."




USA Foreign Policy Thomas L. Friedman

USA Foreign Policy Thomas L. Friedman

Published: August 24, 2013 NYT

IF you follow the commentary on American foreign policy toward Egypt and the broader Middle East today, several themes stand out: People in the region argue: “Whatever went wrong, the United States is to blame.” Foreign policy experts argue: “Whatever President Obama did, he got it wrong.” And the American public is saying: “We’re totally fed up with that part of the world and can’t wait for the start of the N.F.L. season. How do you like those 49ers?”


There is actually a logic to all three positions.
It starts with the huge difference between cold-war and post-cold-war foreign policy. During the cold war, American foreign policy “was all about how we affect the external behavior of states,” said Michael Mandelbaum, the Johns Hopkins University foreign affairs expert. We were ready to overlook the internal behavior of states, both because we needed them as allies in the cold war and because, with the Russians poised on the other side, any intervention could escalate into a superpower confrontation.
Post-cold-war foreign policy today is largely about “affecting the internal composition and governance of states,” added Mandelbaum, many of which in the Middle East are failing and threaten us more by their collapse into ungoverned regions — not by their strength or ability to project power.
But what we’ve learned in Bosnia, Afghanistan, Libya, 
Iraq, Egypt and Syria is that it is very hard to change another country’s internal behavior — especially at a cost and in a time frame that the American public will tolerate — because it requires changing a country’s political culture and getting age-old adversaries to reconcile.
The primary foreign policy tools that served us so well in the cold war, said Mandelbaum, “guns, money, and rhetoric — simply don’t work for these new tasks. It is like trying to open a can with a sponge.”
To help another country change internally requires a mix of refereeing, policing, coaching, incentivizing, arm-twisting and modeling — but even all of that cannot accomplish the task and make a country’s transformation self-sustaining, unless the people themselves want to take charge of the process.
In Iraq, George W. Bush removed Saddam Hussein, who had been governing that country vertically, from the top-down, with an iron fist. Bush tried to create the conditions through which Iraqis could govern themselves horizontally, by having the different communities write their own social contract on how to live together. It worked, albeit imperfectly, as long as U.S. troops were there to referee. But once we left, no coterie of Iraqi leaders emerged to assume ownership of that process in an inclusive manner and thereby make it self-sustaining.
Ditto Libya, where President Obama removed Col. Muammar el-Qaddafi’s top-down, iron-fisted regime, but he declined to put U.S. troops on the ground to midwife a new social contract. The result: Libya today is no more stable, or self-sustainingly democratic, than Iraq. It just cost us less to fail there. In both cases, we created an opening for change, but the local peoples have not made it sustainable.
Hence the three reactions I cited above. People of the region often blame us, because they either will not or cannot accept their own responsibility for putting things right. Or, if they do, they don’t see a way to forge the necessary societal compromises, because their rival factions take the view either that “I am weak, how can I compromise?” or “I am strong, why should I compromise?”
As for blaming Obama — for leaving Iraq too soon or not going more deeply into Libya or Syria — it grows out of the same problem. Some liberals want to “do something” in places like Libya and Syria; they just don’t want to do what is necessary, which would be a long-term occupation to remake the culture and politics of both places. And conservative hawks who want to intervene just don’t understand how hard it is to remake the culture and politics in such places, where freedom, equality and justice for all are not universal priorities, because some people want to be “free” to be more Islamist or more sectarian.
“With the traditional tools of foreign policy, we can stop some bad things from happening, but we cannot make good things happen,” noted Mandelbaum.
For instance, if it is proved that Syria has used chemical weapons, American officials are rightly considering using cruise missiles to punish Syria. But we have no hope of making Syria united, democratic and inclusive without a much bigger involvement and without the will of a majority of Syrians.
And too often we forget that the people in these countries are not just objects. They are subjects; they have agency. South Africa had a moderate postapartheid experience because of Nelson Mandela and F.W. de Klerk. Japan rebuilt itself as a modern nation in the late 19th century because its leaders recognized their country was lagging behind the West and asked themselves, “What’s wrong with us?” Outsiders can amplify such positive trends, but the local people have to want to own it.
As that reality has sunk in, so has another reality, which the American public intuits: Our rising energy efficiency, renewable energy, hydraulic fracturing and horizontal drilling are making us much less dependent on the Middle East for oil and gas. The Middle East has gone from an addiction to a distraction.
Imagine that five years ago someone had said to you: “In 2013, Egypt, Libya, Syria, Tunisia, Yemen and Iraq will all be in varying states of political turmoil or outright civil war; what do you think the price of crude will be?” You’d surely have answered, “At least $200 a barrel.”
But it’s half that — for a reason: “We now use 60 percent less energy per unit of G.D.P. than we did in 1973,” explained the energy economist Philip Verleger. “If the trend continues, we will use half the energy per unit of G.D.P. in 2020 that we used in 2012. To make matters better, a large part of the energy used will be renewable. Then there is the increase in oil and gas production.” In 2006, the United States depended on foreign oil for 60 percent of its consumption. Today it’s about 36 percent. True, oil is a global market, so what happens in the Middle East can still impact us and our allies. But the urgency is gone. “The Middle East is China’s problem,” added Verleger.
Obama knows all of this. He just can’t say it. But it does explain why his foreign policy is mostly “nudging” and whispering. It is not very satisfying, not very much fun and won’t make much history, but it’s probably the best we can do or afford right now. And it’s certainly all that most Americans want.

The MWA is designed to study radio sources at low frequencies, a poorly known part of the radio spectrum between 80 and 300 megahertz. It will be one of the world’s first telescopes without any moving parts.

The project, undertaken by a consortium of research institutions from the host country, the U.S. and the Raman Research Institute in India, seeks to answer these and other great puzzles that have baffled humanity for long.

In fact, the MWA is not a single telescope but a network of 2,048 dipole antennas, which are arranged in an array of 128 ‘tiles’ with each tile consisting of 16 antennas. Scaled down from the original plans for a 512-tile array, the project has cost the consortium A$51 million. The RRI played a crucial role by designing and developing the digital receivers, the hardware that is critical for the radio telescope.

Microwave Tomography

During treatment, magnetic resonance image was supplemented with microwave tomography at the Dartmouth-Hitchcock Medical Center. Regions of high conductivity corresponded to the tumors, low conductivity to normal tissues, and unlike other imaging techniques, body mass index (indicating the amount of body fat), age or breast density did not appear to affect the results.
This imaging technique is low cost and can be repeated at numerous stages during treatment. Paul Meaney from Dartmouth College, who led the study explained, "By recalling patients for scans during their treatment we found that we could actually see tumors shrinking in women who responded to chemotherapy. Microwave tomography could therefore be used to identify women who are not responding to initial therapy and their treatment changed appropriately at an early stage."


PET

Positron Emission Tomography (PET)

PET ­produces images of the body by detecting the radiation emitted from radioactive substances. These substances are injected into the body, and are usually tagged with aradioactive atom, such as Carbon-11, Fluorine-18, Oxygen-15, or Nitrogen-13, that has a short decay time. These radioactive atoms are formed by bombarding normal chemicals with neutrons to create short-livedradioactive isotopes. PET detects the gamma rays given off at the site where a positron emitted from the radioactive substance.
