NSF CAREER Award Winners

Engineer Roy Choudhury wins NSF Early Career Award

Assistant Professor Romit Roy Choudhury has received a 5-year, $437,000 National Science Foundation Early CAREER award. The distinction recognizes and supports the early career development activities of those teacher-scholars who are most likely to become academic leaders
…
“A smart antenna is like a spotlight,” Roy Choudhury explains. “It forms a focused beam that can be used to precisely transmit and receive information. This opens up a new realm of possibilities, including concurrent communications, higher transmission range, better information hiding, etc. In contrast,” he said, “old school ‘dumb’ antennas are analogous to lightbulbs. You turn them on and they spread light everywhere, or in this case, interfere with all the other communications around them.”

“Security and privacy are additional advantages of antenna-aware protocols”, said Roy Choudhury. “By focusing your beams intelligently, you may prevent eavesdroppers form listening to your conversation, and even jam them selectively. Such capabilities have obvious implications for national security.”

Through his NSF CAREER project, named Spotlight, Roy Choudhury plans to develop the theoretical basis for antenna-aware networking, design distributed protocols, and implement them on an experimental testbed.

At the Heart of All Matter

The hunt for the God particle by Joel Achenbach

Physics underwent one revolution after another. Einstein’s special theory of relativity (1905) begat the general theory of relativity (1915), and suddenly even such reliable concepts as absolute space and absolute time had been discarded in favor of a mind-boggling space-time fabric in which two events can never be said to be simultaneous. Matter bends space; space directs how matter moves. Light is both a particle and a wave. Energy and mass are inter- changeable. Reality is probabilistic and not deterministic: Einstein didn’t believe that God plays dice with the universe, but that became the scientific orthodoxy.
…
Most physicists believe that there must be a Higgs field that pervades all space; the Higgs particle would be the carrier of the field and would interact with other particles, sort of the way a Jedi knight in Star Wars is the carrier of the “force.” The Higgs is a crucial part of the standard model of particle physics—but no one’s ever found it.
…
The Higgs boson is presumed to be massive compared with most subatomic particles. It might have 100 to 200 times the mass of a proton. That’s why you need a huge collider to produce a Higgs—the more energy in the collision, the more massive the particles in the debris. But a jumbo particle like the Higgs would also be, like all oversize particles, unstable. It’s not the kind of particle that sticks around in a manner that we can detect—in a fraction of a fraction of a fraction of a second it will decay into other particles. What the LHC can do is create a tiny, compact wad of energy from which a Higgs might spark into existence long enough and vivaciously enough to be recognized.

Car Powered Using Compressed Air

car powered using compressed air

Jules Verne predicted cars would run on air. The Air Car (link broken, so it was removed) is making that a reality. The car is powered by compressed air which certainly seems like an interesting idea. Air car ready for production (link broken, so it was removed, sigh, when will site stop failing the web so badly?):

Refueling is simple and will only take a few minutes. That is, if you live nearby a gas station with custom air compressor units. The cost of a fill up is approximately $2.00. If a driver doesn’t have access to a compressor station, they will be able to plug into the electrical grid and use the car’s built-in compressor to refill the tank in about 4 hours.

The car is said to have a driving range of 125 miles so by my calculation it would cost about 1.6 cents per mile. A car that gets 31 mpg would use 4 gallons to go 124 miles. At $3 a gallon for gas, the cost is $12 for fuel or about 9.7 cents per mile. I didn’t notice anything about maintenance costs. I don’t see any reason why the Air Car would cost more to maintain than a normal car.

The air car was named one of Time magazine’s best inventions of the 2007.

Five-seat concept car runs on air

An engineer has promised that within a year he will start selling a car that runs on compressed air, producing no emissions at all in town. The OneCAT will be a five-seater with a fibre-glass body, weighing just 350kg and could cost just over Â£2,500.
…
Tata is the only big firm he’ll license to sell the car – and they are limited to India. For the rest of the world he hopes to persuade hundreds of investors to set up their own factories, making the car from 80% locally-sourced materials.
…
“Imagine we will be able to save all those components traveling the world and all those transporters.” He wants each local factory to sell its own cars to cut out the middle man and he aims for 1% of global sales – about 680,000 per year. Terry Spall from the Institution of Mechanical Engineers says: “I really hope he succeeds. It is a really brave experiment in producing a sustainable car.”

Virus Engineered To Kill Deadly Brain Tumors

Yale Lab Engineers Virus That Can Kill Deadly Brain Tumors

A laboratory-engineered virus that can find its way through the vascular system and kill deadly brain tumors has been developed by Yale School of Medicine researchers, it was reported this week in the Journal of Neuroscience.

Each year 200,000 people in the United States are diagnosed with a brain tumor, and metastatic tumors and glioblastomas make up a large part of these tumors. There currently is no cure for these types of tumors, and they generally result in death within months.
…
“Three days after inoculation, the tumors were completely or almost completely infected with the virus and the tumor cells were dying or dead,” van den Pol said. “We were able to target different types of cancer cells. Within the same time frame, normal mouse brain cells or normal human brain cells transplanted into mice were spared. This underlines the virus’ potential therapeutic value against multiple types of brain cancers.”

Pretty cool. Too bad these press releases never quite live up to the initial promise. Still this one is very cool, if it can succeed in helping even a small percentage of people it will be a great breakthrough. It is also just cool – using a virus to kill tumors – how cool is that?

Offering Residency to Foreign Engineers and Scientists

Rep. Lofgren wants residency for foreign engineers

Foreign-born engineering, science, and math students in the United States should be automatically granted legal residency when they get a job in this country, said California Congresswoman Zoe Lofgren.

Lofgren, a Democrat, spoke to an audience Friday at the Joint Venture: Silicon Valley conference about threats to innovation in the area. She said that about 56 percent of the Ph.D. candidates at the finest schools in the United States are immigrants, and because of the government’s current immigration policy, many of those people leave the country.

I support such legislation. I also think it is only one, of many measure to take to encourage science and engineering excellence (which will in turn help the economy). I have no doubt that other countries are going to be successful establishing their own global centers of excellence and attract scientists and engineers from around the world: including from the USA. The Curious Cat Science and Engineering Blog now includes a tag cloud on the right side of our home page, tags for this post include: government and economy.

Google Lunar X Prize – First 10 Teams

The X PRIZE Foundation and Google, Inc. today announced the first ten teams to register for the Google Lunar X PRIZE, a robotic race to the Moon to win a remarkable $30 million in prizes. This international group of teams will compete to land a privately funded robotic craft on the Moon that is capable of roaming the lunar surface for at least 500 meters and sending video, images and data back to the Earth.

“We are excited that ten teams from around the world have taken up the challenge of the Google Lunar X PRIZE,” said Megan Smith, Google’s Vice President for New Business Development. “We look forward to the exciting achievements and scientific advancements that will result from the efforts of these teams as they participate in the next great space race.”

The 10 fully registered teams now:

Aeronautics and Cosmonautics Romanian Association (ARCA): Based in Valcea, Romania and led by Dumitru Popescu, ARCA was also a contender in the Ansari X PRIZE. Two of ARCA’s most innovative projects to date have been the Demonstrator 2B rocket and Stabilo, a two-stage manned suborbital air-launched vehicle. The craft they plan to enter in the Google Lunar X PRIZE will be called the “European Lunar Explorer.”

Astrobotic: Team Astrobotic, led by Dr. William “Red” Whittaker, was formed to coordinate the efforts of Carnegie Mellon University, Raytheon Company and additional institutions. One of Carnegie Mellon’s specialties is autonomous navigation through stereo vision and other technologies. This enables Carnegie Mellon’s robots to automatically avoid obstacles and select their own route across unmapped terrain. Astrobotic will compete for the prize using their “Artemis Lander” and “Red Rover.”

High School Students in USA, China and India

2 million minutes is a documentary film looking at education in USA, China and India. The producers offer a blog, What Should America Do?, which is interesting.

this blog offers deeper insights into education in China, India and the United States, and the challenge America faces. Now you can join a dialog about what governments, communities and families should and are doing to best prepare US students for satisfying careers in the 21st century.

U.S. Students Can’t Compete in High-Tech World

The film follows two students from Carmel High School in Indianapolis, as well as two students from India and two from China. The premise is that they all have roughly 2 million minutes in high school to build their intellectual foundation and prepare for college and a career.

Twenty months in the making, “2 Million Minutes” highlights the pressures and priorities of these students and their families. Ultimately, it provides insight into the changing nature of competition in a technology-based global economy.
…
“As a high-tech entrepreneur and venture capitalist for the past 25 years,” Compton said,” I can tell you the people who have reaped the greatest economic rewards in the past two decades have been those with the most rigorous and thorough understanding of technology — and thus a solid foundation in math and science — and who have an ability to solve problems and possess entrepreneurial skill.”

I strongly agree with the economic benefits from strong science and engineering education and the personal benefit of science and technology expertise (one small example: S&P 500 CEOs – Again Engineering Graduates Lead).

Engineering Education at Smith College

How to Re-engineer an engineering major at a women’s college:

The first women’s college to offer an engineering degree, Smith is forging new paths in a field that’s eager to swell its ranks in the United States. Women receive only 20 percent of bachelor’s degrees in engineering, according to a new report by the National Science Board (NSB). Like a handful of other liberal arts colleges, Smith is producing graduates who’ve had a different type of engineering education – one that goes beyond technical training to focus on a broader context for finding solutions to humanity’s problems; one that emphasizes ethics and communication; one so flexible that about half the students study abroad, which is rare, despite the multinational nature of many engineering jobs.
…
Smith’s program boasts a 90 percent retention rate and high participation of underrepresented minorities. Ms. Moriarty hopes to find out which elements of the experience at Smith most contribute to students’ success. Female role models play a part (6 out of 10 engineering faculty here are women), but she says other factors are likely to be more important: “I think the methods being used here could probably translate very easily to other institutions that aren’t all women,” she says.

One Step Closer to Holographic TV

UA team creates new holographic display

A 3-D holographic image that can be updated and viewed without special glasses may soon find its way from a UA optics lab to operating rooms and battlefield command centers.
…
That holographic bird on your credit card can’t turn into something else every few minutes, but Tay’s display can take an image rendered in three dimensions — initially photographed or computer-generated — and display it on the display surface, followed by another and another.

In addition, the device requires no special glasses or headgear to see the image, unlike present-day virtual-reality systems.
The scientists who worked on the device first speak of using it as an aid in brain surgery or as a close-to-real-time battlefield display, but Tay and UA optical sciences professor Nasser Peyghambarian are not unaware of its much more commercial potential.
…
The heart of the innovation, says Tay, is the photorefractive polymer — a thin plastic film that reacts to light — that can hold an image indefinitely and be updated. Tay says the method that allowed the polymer to hold the image and update it came to him “out of the blue” while at a meeting about that very problem.
…
Cramming the pinball- machine-size collection of equipment into a “table-top” commercial unit is also possible, Tay says, but a challenge. Tay says the work, which started about two years ago, was done in collaboration with Nitto Denko Technical Corp. and was funded by the U.S. Air Force Office of Scientific Research.
