Engineering Education Online Seminars

The Center for Engineering Educational Outreach has an engineering education seminar series that is available online: register for online broadcasts of all the remaining Tufts CEEO Seminar Series speakers for Spring 2008.

Some excellent seminars allow online participants are able to submit questions to the speaker via chat at the end of the seminar (time permitting). “Due to resource limitations, CEEO Spring 2008 Seminar Series are not currently being archived for later viewing or download.” That is a shame shame. They should post them on You Tube or SciVee or something. The advantage of asynchronous distribution of valuable content should be provided given the available tools today.

6 Inch Bat Plane

A six-inch robotic spy plane modeled after a bat would gather data from sights, sounds and smells in urban combat zones and transmit information back to a soldier in real time.

That’s the Army’s concept, and it has awarded the University of Michigan College of Engineering a five-year, $10-million grant to help make it happen. The grant establishes the U-M Center for Objective Microelectronics and Biomimetic Advanced Technology, called COM-BAT for short. The grant includes an option to renew for an additional five years and $12.5 million.

U-M researchers will focus on the microelectronics. They will develop sensors, communication tools and batteries for this micro-aerial vehicle that’s been dubbed “the bat.” Engineers envision tiny cameras for stereo vision, an array of mini microphones that could home in on sounds from different directions, and small detectors for nuclear radiation and poisonous gases.

Low-power miniaturized radar and a very sensitive navigation system would help the bat find its way at night. Energy scavenging from solar, wind, vibration and other sources would recharge the bat’s lithium battery. The aircraft would use radio to send signals back to troops.

“These are all concepts, and many of them are the next generation of devices we have already developed. We’re trying to push the edge of our technologies to achieve functionality that was not possible before,” said Kamal Sarabandi, the COM-BAT director and a professor in the U-M Department of Electrical Engineering and Computer Science.

COM-BAT also involves the University of California at Berkeley and the University of New Mexico. It is one of four centers the Army launched as a collaborative effort among industry, academia and the Army Research Laboratory to work toward this vision of a small, robotic aircraft that could sense and communicate. Each of the four centers is charged with developing a different subsystem of the bat, a self-directed sensor inspired by the real thing.

$10 Million X Prize for 100 MPG Car

Progressive Automotive X PRIZE

The window for applications will be open until mid 2008, when a thorough qualification process will assess safety, cost, features and business plans to ensure that only production-capable, consumer-friendly cars compete. Those that qualify will race their vehicles in rigorous cross-country stage races in 2009 and 2010 that combine speed, distance, urban driving and overall performance. The winners will be the vehicles that exceed 100 MPG, meet strict emissions standards and finish in the fastest time. Host cities involved in the competition route are to be announced shortly.

Contractor Warned NYC About Crane

Contractor warned city about crane but was blown off

A retired contractor warned the city 12 days ago the doomed crane on E. 51st St. wasn’t properly braced, but the Buildings Department blew him off after making a cursory check. “I think the Buildings Department is grossly negligent because they had been warned. They sent an inspector and they brushed it under the rug, so to speak,” said Bruce Silberblatt, an 80-year-old former contractor.

“Now, I’m sitting here and, at last count, four people are dead and a couple buildings on 50th St. are completely wrecked. … It looks like Baghdad over there.” Silberblatt said he called the city at 3 p.m. on March 4 because he had been concerned for days about the lack of braces securing the crane at a construction site near his United Nations Plaza home.
…
Early yesterday, Silberblatt watched as the crane was lifted about 50 feet higher into the air. That left almost 150 feet of the massive white crane unsecured, he estimated. “That to me is unstable,” he said. “It’s too heavy. You don’t have to be an engineer to understand that.” Hours later, Silberblatt’s worst fear was realized: The crane toppled over, splitting in two after it crashed into one building, and then flattening a four-story building.
…
Stephen Kaplan, owner of the construction company managing the site, Reliance Construction Group, said the crane became dislodged after a piece of steel fell and severed one of its ties. “It was an absolute freak accident,” Kaplan told The Associated Press. “All the piece of steel had to do was fall slightly left or right, and nothing would have happened.” Silberblatt called that explanation nonsense.

Update: Inspector Is Charged With Filing False Report Before Crane Collapsed

Grade School Engineering

Reading, Writing … And Engineering

More than 2,200 middle and high schools use engineering courses offered by Project Lead the Way, a Clifton Park, N.Y., nonprofit that receives industry support, up from just 12 when the initiative started in 1997. And Infinity Project, developed out of Southern Methodist University in Dallas, is now in 300 schools, up from 12 in 1999. The impact of these initiatives on the ranks of engineers remains to be seen.

Besides creating curricular approaches, groups are lobbying state governments to add engineering to their education standards.

Massachusetts included engineering content in its state science requirements for grades K-12 starting in 2001. New Hampshire began sprinkling engineering and technology concepts into its science curriculum starting last school year. New Jersey incorporated engineering concepts into its state education standards starting in 2004. And more states are following: Texas is working on creating standards for an engineering course that can be used to fulfill a high-school science credit.
…
Teaching through problem-solving storybooks that feature characters from around the globe “becomes a lot richer and is liberating for many kids and many teachers,” she says. The curriculum can cost as little as $40 — the price of a teacher’s binder, including lesson plans and one storybook. For about $6,000, a school could furnish materials, refills and a storybook for each student in every grade.

Technology and Fun in the Classroom

Bridging technology with fun

Mitch Lown and Dave Arndt teach technology education to students at Bangor High School and West Salem High School. A few of the courses they teach were once, years ago, called “shop class,” but the curriculum is far more advanced today. Not only are these not your father’s shop classes, they aren’t shop classes at all.

Computer programs, 3-D designs, architectural drawing, engineering, mass production and the design and marketing of products are only some of the areas local high school students are tackling in Lown and Arndt’s classes.
…
In their manufacturing classes, both Lown and Arndt give students a feel for what it’s like to set up a business and produce and sell a product. And they do make a profit. Lown’s students, for example, built and sold mounting kits for deer antlers and made a profit on the venture. Arndt said he always stays conscious of the world that students will face after graduation.

“I address every class as if it’s a job,” he said. “We’re not here to waste time because that’s not the way it’s going to be when they get in the job market. The biggest challenge for me is changing the attitudes of some students and instilling a work ethic. If they say they are going to do something, they need to follow through on that.”

#1 Engineering Blog

Right now we are the number one rated engineering blog on blogged (with a 9.1 excellent rating). We are also the first Google result for engineering blog – #1 on Yahoo too, but not on MSN. Well, it seems to me, MSN needs to improve their search results :-).

Google Tech Webcasts #4

While I worked in the Eisenhower Executive Office Building (EEOB) – part of the white house complex, I was able to hear some great speakers. However, those talks were only available to those of us that could make it to room 450 of the EEOB when it was scheduled. Google has far more speakers and they have posted webcasts of those talks online. It is great stuff, some excellent recent examples:

Michael Pollan on In Defense of Food – related: Eat food. Not too much. Mostly plants.
Cory Doctorow on Overclocked: Stories of the Future Present
Annalee Newitz, Charlie Anders, Ellen Spertus, & Jenn Shreve discuss their book She’s Such a Geek: Women Write About Science, Technology, and Other Nerdy Stuff
Daniel Goleman on Social Intelligence: The New Science of Human Relationships

Seeking Solar Supremacy

The dance of the particles

Engineering professors Ray LaPierre, who is working with Cleanfield on solar cells made from a dense turf of nanowires, and Adrian Kitai, who co-founded Flexible Solar to make bendable solar panels that are less costly to manufacture, are showing how skills typically prized in the telecom sector can be repurposed to build better solar technologies.

Similar efforts are also being made at the University of Toronto’s Institute for Optical Sciences, where a new spin-off called The Solar Venture aims to improve the economics of solar. “Ontario was a global leader in telecom, but now that has slowed down,” says Rafael Kleiman, professor of engineering physics and director of McMaster’s Centre for Emerging Device Technologies. “All the people, all this research (in telecom), is finding a new home. I really believe Ontario can make itself a global hub in solar photovoltaic technologies.”
…
A solar cell is just a big specialized chip, so everything we’ve learned about making chips applies,” Paul Saffo, an engineering professor at Stanford University, recently told the New York Times. There’s a reason why California’s Silicon Valley, the headquarters of data-networking king Cisco Systems and semiconductor goliath Intel, is positioning itself as Solar Valley.

All around the world people are aiming to create centers of excellence for solar power research and production.

Google Summer of Code 2008

Over the last three years Google Summer of Code has provided 1500 students from 90 countries the chance to work on open source projects. It also has provide some great software and software enhancements to the open source community. Google has increased their funding by another $1 million. Each participant will receive $4,500 as a stipend.

I don’t understand why they have such a short window of opportunity to apply – but this is how they do it every year. They are accepting applications from open source projects, to act as mentoring organizations, through March 13th. Student applications will be accepted from March 24th to March 31st. See Google’s announcement.
