Water Jacket

Four youths design India’s first water jacket:

Four engineering students, have designed a water jacket, a wearable vest capable of holding water that when strapped to the body, provides a cushioning effort to the wearer by distributing the weight of the water evenly.

“About 20 kg of water can be stored in this jacket – 10 in the front chamber and an equal volume of liquid in the back chamber. The chambers are designed to maintain a balance in the body so that no part of the body gets strained,” says T R Neelakantan, one of the innovators, who was recently awarded National Innovation Foundation’s (NIF) fourth national awards by President A P J Abdul Kalam in New Delhi.

The other three contributors are Balaji T K, Kunal Kumar and Arun Rosh, all students at the S R M Engineering College, Chennai.

Hiring Software Developers

Interviewing and Hiring by Tom Van Vleck

“Let’s take a break from talking to people. Why don’t you have a seat in this empty office, and write a small program. Use any language you want to. The program can do anything you’d like. I’ll be back in about 30 minutes, and ask you to explain the program to me.”
…
It seemed reasonable, if the job was programming, to ask people how they felt about actually doing some. And sure, it caused interview stress. We allowed for that in our evaluation; but the job was going to be stressful at times too, and we needed people who could enjoy it. The important thing was not what the candidate wrote, but the account he or she gave of it.
…
And you’d be surprised how many people couldn’t do it. Couldn’t write a simple program and talk sensibly about it. They’d huff, and bluster, and make excuses, and change the subject, rather than actually write some code. “Oh, I think of myself as more an architect than a coder.”

Mobilizing Tomorrow’s Engineers

Girl Day And Global Marathon: Mobilizing Tomorrow’s Engineers:

For the past seven years, the National Engineers Week Foundation has focused on diversifying the ranks of engineering with efforts to reach young women and girls, especially during the annual Introduce a Girl to Engineering Day, this year slated for Thursday, February 22 during Engineers Week 2007, February 18-24, and in a more recent venture, the Global Marathon For, By and About Women in Engineering, scheduled for March 22 and 23.

“Girl Day,” as it’s known among engineers, is the only outreach of its kind aimed at a single profession. On February 22, and then in programs continued throughout the year, women engineers and their male counterparts reach as many as one million girls with workshops, tours, speaking engagements, on-line discussions and a host of other activities that showcase engineering as an important career option for everyone.

Page: Marketing Science

Google’s Page urges scientists to market themselves:

And that was his main advice to the scientists in the room: take their scientific studies, market them better and make them readily accessible to the world. That way, the world might have a better chance at solving problems like energy consumption, poverty and global climate change.

“Virtually all economic growth (in the world) was due to technological progress. I think as a society we’re not really paying attention to that,” Page said. “Science has a real marketing problem. If all the growth in world is due to science and technology and no one pays attention to you, then you have a serious marketing problem.”

To that end, Page urged the group to take on more leadership roles in society, i.e., politics, so that they could control more funding for research and development. He also said that scientists should get in the habit of investing part of their scientific grant money to marketing budgets, in order to get the word out to the media about their research.

Entrepreneurialism should also be more ingrained in university culture, Page said, much like it is at his alma mater Stanford University and Google’s home-base, Silicon Valley. Finally, he called on the scientists to make more of their research available digitally. Even though Google Scholar tries to open access to scientific work, it still falls short.

Iowa Grapples with Engineer Shortage

State grapples with engineer shortage:

“In the past four years or so, it’s become increasingly difficult to fill positions, especially for people who have experience and can come in with a good skill set,” Dougherty said. “In some instances, you simply go without filling those jobs for a long time.”

Loren Zachary, an assistant dean at the ISU College of Engineering, said enrollment has been mostly in a downward trend over the past six years. In 2001, the college had 1,556 new freshmen; in the fall of 2006, freshman enrollment was 1,213, which was up slightly from 2005’s enrollment of 1,155. Of the 800 or so students who graduate with a bachelor’s degree in engineering from ISU each year, more than 60 percent leave the state for employment, according to Hanneman’s figures.

“Certainly you have a lot of engineering students who are leaving the state,” said the IES’s Scott. “You’ll always have that because the universities attract many out-of-state students.” Zachary said ISU has only a small number of engineering students who are women or minorities. For the current academic year, 14.5 percent of undergraduate engineering students are female. These are two demographics the university is targeting to boost enrollment. “We need more females in engineering,” Zachary said. “It’s an untapped market for us.”

The article mentions several programs for primary and secondary school students we have mentioned previously: Project Lead the Way, Math Counts and FIRST LEGO League

VirtuSphere

The VirtuSphere platform consists of a large hollow sphere that sits on top of a base and allows the sphere to rotate 360 degrees. Wearing a wireless, head-mounted display, users can step inside the sphere to fully interact in immersive virtual environments. The VirtuSphere enables 6 degrees of freedom – one can move in any direction; walk, jump, roll, crawl, run over virtually unlimited distances without encountering real-world physical obstacles.

VirtuSphere systems are made to client specifications and typically include an easy-to- assemble sphere, a base platform that enables it to rotate, a head-mounted display, 3D sensors, sphere rotation trackers, a computer, device drivers and 3D software applications.

$35 million to the USC School of Engineering

The 2006 Slate 60: Donations

Ming Hsieh, 50, founder of Cogent, a technology firm in Pasadena, Calif., that specializes in sophisticated identification systems including fingerprinting, gave $35 million to the University of Southern California’s Viterbi School of Engineering in Los Angeles to coincide with the 100th anniversary of its electrical-engineering program. Hsieh (pronounced “shee”) graduated from the university in 1984 with a master’s degree in electrical engineering after earning his bachelor’s degree in the same field a year earlier. In exchange for this gift, his first to the university, the department has been renamed in his honor. Born on a rice farm in northern China, Hsieh grew up very poor. As a child, he constructed small radios and televisions from spare parts, according to a university spokesman. His interest in electronics was stoked by an uncle, and Hsieh emigrated to the United States to attend college after coming into an inheritance. He recently became a naturalized U.S. citizen.

Aussies Look to Finnish Innovation Model

Aussies look to Finnish Innovation Model:

Australian policy makers are looking to Finland for inspiration in their drive to bring the nation closer to the dream of thriving technological innovation. The country’s president and other Finnish representatives are in Sydney to share with Australian researchers the strides the nation has made in the past three decades. Home of companies such as Nokia, the world’s largest mobile phone manufacturer, Finland has captured the attention of governments looking to shift their economic base away from traditional industries towards a more innovative focus.

Finland’s research and development spend accounts for 3.5 per cent of its gross domestic product (GDP), a higher percentage than that of most European Union nations. It intends to lift this percentage to four per cent by 2010. Australia’s spending on research in comparison was 1.8 per cent of GDP in 2004/05, below the Organisation for Economic Cooperation and Development (OECD) average of 2.3 per cent.

Using IT to Improve Construction

Teicholz awarded top construction engineering prize:

One of CIFE’s biggest innovations is a program that visualizes the various stages of a construction project over time using 3-D models, like a digital movie. The models, which integrate hundreds of building components in an understandable way, can be shared early in the design stage and can straightforwardly communicate a complex schedule to everyone, Teicholz says. “Better decisions can be made about every aspect of the design rather than trying to improve the design after everyone has completed their work,” he says.

The need to correct mistakes after the fact is seen all too often in construction projects, says Martin Fischer, professor of civil and environmental engineering and current CIFE director. Walls built prematurely might have to be torn down, for example, or two work crews that did not communicate might plan to be in the same place at the same time. Time, labor and materials are wasted, and the final cost of the project increases.

Cost of Powering Your PC

The cost of leaving your PC on

Have you ever wondered how much it’s costing you to leave a computer on 24 hours a day, 7 days a week?
…
Here’s the kilowatt-hour calculation for my server, which draws ~160 watts: 160 watts * (8,760 hours per year) / 1000 = 1401.6 kilowatt-hours

The other thing you’ll need to know is how much you’re paying for power in your area. Power here in California is rather expensive and calculated using a byzantine rate structure. According to this recent Mercury News article, the household average for our area is 14.28 cents per kilowatt-hour. 1401.6 kilowatt-hours * 14.28 cents / 100 = $200.15 So leaving my server on is costing me $200 / year, or $16.68 per month. My home theater PC is a bit more frugal at 65 watts. Using the same formulas, that costs me $81 / year or $6.75 per month.

Power could cost more than servers, Google warns: “A Google engineer has warned that if the performance per watt of today’s computers doesn’t improve, the electrical costs of running them could end up far greater than the initial hardware price tag.”
