Transferring Train Passengers Without Stopping

The webcast shows a train transferring passengers without stopping. Essentially passenger modules are picked up and dropped off at each station. Looks pretty cool and would seem to require somewhat complex engineering - which can be a problem as complexity allows for more things to go wrong. Still it looks pretty cool. The sound is not in English but you can see what the idea is.

Inventor rolls out efficient non-stop train system

Taking the Kaohsiung MRT system as an example, Peng says that its maximum speed is 85 kph. Because it must stop at every station, it achieves an average speed over its route of just 35 kph. If the non-stop system were in place, the top velocity of 85 kph could be maintained throughout the system, saving time and energy.

Turtle Camps in Malaysia

Drawing of sea turtles

Pelf Nyok has posted drawing of turtle camps students that she taught in Malaysia. On the image shown on the left:

The third poster shows the threats that our turtles are facing — a turtle is trapped in a fisherman’s net, a turtle is consuming a plastic bag, which it mistakes as a jellyfish, and there are rubbish on the sea floor.

Pelf is on her way to the USA for turtle conservation training on the Asian Scholarship Program for in-situ Chelonian Conservation:

a 4-month scholarship, and involves professional training in the conservation of turtles (including sea turtles, freshwater turtles and tortoises, I presume). The flow of the program has yet to be finalized but according to the Director of the Program, we (the Laotian student and I) would be spending one month visiting turtle scientists and turtle research centers in New Jersey, Tennessee, Florida and maybe California.

And the remaining 3 months would be spent at the Wetlands Institute at Stone Harbor, New Jersey. The training will be conducted at the Wetlands Institute, together with other local participants.

First Lungless Frog Found

First Lungless Frog Found

The first recorded species of frog that breathes without lungs has been found in a clear, cold-water stream on the island of Borneo in Indonesia. The frog, named Barbourula kalimantanensis, gets all its oxygen through its skin.

Previously the only four-limbed creatures known to lack lungs were salamanders. A species of earthwormlike, limbless amphibian called a caecilian is also lungless. Tetrapods, or four-limbed creatures, that develop without lungs are rare evolutionary events, Bickford and colleagues write.

The trait in amphibians is likely an adaptation to life between water and land and their ability to respire through the skin. The researchers suggest lunglessness in B. kalimantanensis may be an adaptation to the higher oxygen content in fast-flowing, cold water.

Wake added that for most amphibians, the majority of gas exchange happens through the skin. A low but significant amount of respiration occurs via simple, sac-like lungs. Most species, he noted, have mating calls that require lungs. So biologists are unsure why a few species have entirely gotten rid of the organs, Wake said.

Honda Engineering

Inside Honda’s brain by Alex Taylor III

why is Honda playing with robots? Or, for that matter, airplanes? Honda is building a factory in North Carolina to manufacture the Hondajet, a sporty twin-engine runabout that carries six passengers. Or solar energy? Honda has established a subsidiary to make and market thin-film solar-power cells. Or soybeans? Honda grows soybeans in Ohio so that it can fill up cargo containers being shipped back to Japan. The list goes on. All this sounds irrelevant to a company that built some 24 million engines last year and stuffed them into everything from cars to weed whackers.

On fuel cells, Honda is literally years ahead of the competition. The FCX Clarity will go on sale in California this summer. It is powered by a fuel cell that uses no gasoline and emits only water vapor. Though mass production is at least a decade away, the Clarity is no mere test mule. Elegant and efficient, its hydrogen-powered fuel-cell stack is small enough to fit in the center tunnel - a significant improvement over other, bulkier power packs - and robust enough for a range of 270 miles.

The wellspring of Honda’s creative juices is Honda R&D, a wholly owned subsidiary of Honda Motor. Based in Saitama, west of Tokyo, R&D engineers create every product that Honda makes - from lawn mowers to motorcycles and automobiles - and pursue projects like Asimo and Hondajet on the side. Defiantly individualistic, R&D insists on devising its own solutions and shuns outside alliances. On paper it reports to Honda Motor, but it is powerful enough to have produced every CEO since the company was founded in 1948.

The engineer in Fukui [Honda's president and CEO] cannot help but be intrigued by what his former colleagues are up to, and his office is only a few steps away from Kato’s. But even with the CEO just down the hall, says Kato, “We want to look down the road. We do not want to be influenced by the business.”

Honda allows its engineers wide latitude in interpreting its corporate mission. “We’ve been known to study the movement of cockroaches and bumblebees to better understand mobility,” says Frank Paluch, a vice president of automotive design. Honda R&D gets about 5% of Honda’s annual revenues. Most of the money goes to vehicle development, not cockroach studies

mistakes like the Insight are also the exception. R&D has provided Honda with a long list of engineering firsts that consumers liked, including the motorcycle airbag, the low-polluting four-stroke marine engine, and ultralow-emission cars.

Education is Opportunity

Google, Gates, Indian Diaspora Bet on Children by Andy Mukherjee

Yogi Patel, a retired chemical engineer and motel owner from Dallas, was nearing the end of his presentation about the need to tackle illiteracy in India when he put up a slide showing a thumb impression: his dad’s. “I’ve never needed anyone to tell me just how important education is,” Patel said last weekend to a gathering of the Indian diaspora in Singapore. “I’ve seen it in my own life.”

Born into a poor, illiterate family in the western Indian state of Gujarat, Patel was lucky to break free of the poverty trap. Several people from his community had prospered in East Africa. They supported his studies.

at 30 U.S. cents per child per year, the basic math, reading and writing skills required to help young learners retain their interest in education and keep them from dropping out of school are ridiculously cheap. It’s also critical enough to have caught the attention not just of wealthy Indian communities overseas but also of the Menlo Park, California-based William and Flora Hewlett Foundation and the Bill & Melinda Gates Foundation.

Together, the two charities offered to help 10 million students for three years by pledging $9 million last year to Read India, an initiative of Pratham, a Mumbai-based not-for- profit organization for which Patel is a fund-raiser. Google.org, the philanthropic arm of Google Inc., chipped in last month with a $2 million grant to help fund Pratham’s annual survey of the qualitative aspects of primary education in India.

YouTube Access Denied

Millions of users around the globe could not access YouTube for a couple hours yesterday. Why?

Well to understand, we need to start with how you normally connect to a web site. You click on a link to youtube.com. Your ISP looks up the internet address for youtube.com by looking at internet routing tables. Each domain has a name server that provides the IP address for where it should be found (for example, an IP address that shows youtube.com is 208.65.153.238).

Well what happened in this case is Pakistan decided to prevent anyone in Pakistan from accessing YouTube because the government didn’t like some video. The way Pakistan decided to accomplish this was to update their routing table to just direct all traffic that was meant to go to YouTube to a phony address which would then return nothing.

Why did many outside of Pakistan lose access to YouTube? Well their version of the routing table leaked out of Pakistan through PCCW (large internet provider), Then other internet providers adopted the incorrect information, until many around the globe were being directed to the wrong place.

You might find it amazing the routing system could allow such a thing to happen - it doesn’t seem very secure. You are right, that it doesn’t seem very sensible. When the internet was created some protocols were established that made sense then but don’t necessarily make sense for what the internet has become.

The problem was fixed when Google’s YouTube engineers contacted PCCW to inform them of the problem and have them correct it. I think if it was my site instead, I would have had difficulty figure out what was going on :-) Once PCCW corrected their routing tables the fixed flowed through the system and everyone was able to see the great stuff like Marissa Mayer discussing Innovation at Google.

I would imagine Internet2 (well on its way to a computer near you) and IPv6 will take not be so venerable to such a mistake.

China’s Technology Savvy Leadership

China’s Sci-Tech Savvy Leadership by Jocelyn Ford

Until last year, the top nine members of China’s politburo were ALL trained engineers! And guess what? The Communist Party made innovation and global leadership in science and technology national goals.

Ancient China is famous for its early scientific advances, some of which predated western developments by centuries. Its inventions include paper, printing, gunpowder and the compass.

Leadership does matter, but so does the system. It seems to me it should take a lot longer for China to build a sci-tech friendly system than for the U.S. to bring in sci-tech friendly leadership. That’s where you come in Ira & co.

If I may make one final comment: in my ideal world, borders shouldn’t matter. Victory by the best system, with the best leaders, will hopefully be a victory for all earthlings.

CHINA’S POLITBURO (2007): Decline of the engineer. Last fall China introduced a new top lineup that included two law graduates, as well as an economist, and graduates in history, journalism, management and business administration.

I agree that the increase in science and engineering investment around the globe is a positive development. But the USA faces loses that it has enjoyed due to past technology leadership.

China benefits greatly from such scientific knowledge at the highest level of government. The top 9 leaders in China are know as the “Politburo Standing Committee,” the new additions in 2007 were:

Xi Jinping, 54, studied chemical engineering at the Qinghua University and later earned a doctorate in law.

Li Keqiang, 52, obtained MA and doctorate of Economics after attending the on-the-job postgraduate program on Economics at the School of Economics of Peking University.

He Guoqiang, 63, B.S. Beijing Institute of Chemical Engineering.

Zhou Yongkang, 64 “Graduated from the Exploration Department, Beijing Petroleum Institute, majoring in geophysical exploration. With a university education. Senior engineer with a rank equivalent to professor. ” Funny, I don’t remember any U.S. politician exalting their experience as “equivalent to a professor.”

They joined the nine-member echelon with the five remaining members of the previous standing committee, namely Hu Jintao, Wu Bangguo, Wen Jiabao, Jia Qinglin and Li Changchun.

Korean Engineering Education

Different Engineering Education Expectations

The “Engineering Education Innovation Center” of the engineering department at Yonsei University surveyed 350 human resources officials at some 100 small- and medium-sized companies, as well as big companies, including Samsung Electronics, LG Electronics, Doosan Heavy Industries and Construction, and Nexon. In the survey, they gave engineering graduates an “F” grade in 13 out of 14 categories. Engineering graduates themselves also said, “Education in college is not useful to our work.”

On the contrary, however, engineering professors gave high marks of 97 out of 100 on their knowledge, and answered positively regarding their teaching skills, which revealed the different views colleges and companies have.

The conflict between what is being taught and what is needed in business is the subject of continuing debate globally.

Ranking Universities Worldwide

The Webometrics Ranking of World Universities provides another estimate of the top universities. The methodology is far ideal however I still find it interesting. The various attempts to rank schools can provide a general idea of impact of various institutions (though the measures are fairly crude). Still a sensible picture (especially at the country level) can emerge. And the various rankings should be a able to track shifts in the most influential institutions and relative country strength over time. How quickly those rankings track changes will vary depending on the measures used. I would imagine most will lag the “real” changes as it is easy to imagine many measures that would lag. Still, as I have said before, I expect the USA will lose in relative ranking compared to China, India, Japan, Singapore, Mexico…

The ranking methodology used here weighed rankings in: Jiao Tong academic rankings, Essential Science Indicators, Google Scholar, Alexa (a measure of web site visits to universities) and The Times Higher World University Rankings.

Himalayas Geology

Mystery of the Himalayas Solved:

The mystery of why the Himalaya mountains and the Tibetan plateau are the highest in the world has at last been answered, with the discovery of a gigantic chunk of rock slowly sinking towards the centre of the Earth. When the massive slab - up to eight times the area of the UK and as thick as a dozen Everests on top of each other - dropped off, the lighter crust above it rebounded upwards like a cork released under water, geophysicists say. This “sudden uplift” would have raised the Himalayas by as much as 2km (1.24 miles) to their present height.

If not for the surge, Sir Edmund Hillary and Sherpa Tenzing Norgay might have found themselves reaching the “roof of the world” by conquering Aconcagua (6,962m) in Argentina while Everest languished at a mere 6,848m above sea level, 2,000m below its actual peak. The discovery of the missing mantle - the cold, heavy rock beneath the crust - was revealed last week by Professor Wang-Ping Chen at the University of Illinois, whose team used more than 200 super-sensitive seismometers strung across the Himalayas, from India deep into Tibet.

But some scientists remain sceptical. One geologist at Cambridge, who wanted to remain anonymous because he hadn’t yet read Professor Chen’s paper, suggested that the slab could be the remains of the Tethys Ocean plate. Professor England counters that both the Asian and Indian plates have moved north since then

Asia: Rising Stars of Science and Engineering

Great report - The Atlas of Ideas: How Asian innovation can benefit us all by Charles Leadbeater and James Wilsdon:

Each country will develop differently. In South Korea strong government support has created a world-class information infrastructure.

China is mobilising massive resources for innovation through ambitious long-term plans, funded by rapid economic growth. Beijing’s university district produces as many engineers as all of western Europe. China is developing world-class universities and attracting multinational innovation centres.

India’s elite, trained at the Indian Institutes of Technology, are second to none. New institutions like the National Science and Engineering Foundation could energise a disjointed innovation system. Yet India’s innovation elite may face a rural backlash. Its infrastructure is in poor repair and cities like Bengalooru are congested. Even the much-vaunted IITs do not, unlike their US counterparts, animate innovation clusters.

Open Course Ware from Japan

Soccer Robots from Osaka University

A number of Japanese Universities are creating open courseware, in cooperation with MIT’s OpenCourseWare initiative (which has spawned the OCW Consortium).

Osaka University OpenCourseWare offers courses in English including: Theory in Materials Science | Fluid-Solid Multiphase Flow

Kyoto University OpenCourseWare aims to:

share information in consideration of the fact that sixty percent of visitors to MIT’s OCW project come from Asia. We will make active use of Japanese in building OpenCourseWare, to recruit talented students from all over Asia as well as to promote the Kyoto University education, with Kyoto’s culture and traditions, to the world at large.

Many of the courses are available in Japanese, some are available in English, including: Applied Pharmacology

Tokyo Tech OpenCourseWare courses include: Advanced Signal Processing - Guided Wave Circuit Theory and Mixed Signal systems and Integrated Circuits.

The Nagoya University OpenCourseWare brings free courseware to the Internet. Currently several courses are available in English including, Basics of Bioagricultural Sciences. They aim to post 25 courses initially.

Diplomacy and Science Research

Today more and more locations are becoming viable for world class research and development. Today the following have significant ability: USA, Europe (many countries), Japan, Canada, China, Brazil, Singapore, Israel, India, Korea and Australia (I am sure I have missed some this is just what come to mind as I type this post) and many more are moving in that direction.

The continued increase of viable locations for significant amounts of cutting edge research and development has huge consequences, in many areas. If paths to research and development are blocked in one location (by law, regulation, choice, lack of capital, threat of significant damage to the career of those who would choose such a course…) other locations will step in. In some ways this will be good (see below for an explanation of why this might be so). Promising new ideas will not be stifled due to one roadblock.

But risks of problems will also increase. For example, there are plenty of reasons to want to go carefully in the way of genetically engineered crops. But those seeking a more conservative approach are going to be challenged: countries that are acting conservatively will see other countries jump in, I believe. And even if this didn’t happen significantly in the area of genetically engineered crops, I still believe it will create challenges. The ability to go elsewhere will make those seeking to put constraints in place in a more difficult position than 50 years ago when the options were much more limited (It might be possible to stop significant research just by getting a handful of countries to agree).

Debates of what restrictions to put on science and technology research and development will be a continuing and increasing area of conflict. And the solutions will not be easy. Hopefully we will develop a system of diplomacy that works, but that is much easier said than done. And the United States will have to learn they do not have the power to dictate terms to others. This won’t be an easy thing to accept for many in America. The USA will still have a great deal of influence, due mainly to economic power but that influence is only the ability to influence others and that ability will decline if diplomacy is not improved. Diplomacy may not seem to be a science and engineering area but it is going to be increasingly be a major factor in the progress of science and engineering. (more…)

China challenges dominance of USA, Europe and Japan

China challenges dominance of USA, Europe and Japan in scientific research according to UNESCO Science Report 2005

The report says that “the most remarkable trend is to be found in Asia, where gross expenditure on R&D has grown from a world share of 27.9% in 1997 to 31.5% in 2002”.

This hardly seems impressive compared to the growth of Google say. However the amounts of money for global R&D are huge and so changes as less dramatic than other areas. Still this is significant and seems likely to continue to move in this direction.

Science and Engineering Doctoral Degrees Worldwide

Lagging Engineer Degrees a Crisis by Kevin Hall:

Relative to the sizes of their populations, Asian nations are graduating five times as many undergraduate students in engineering as the United States. A study by Engineering Trends determined that the United States ranks 16th per capita in the number of doctoral graduates and 25th in engineering undergraduates per million citizens.

U.S. universities continue awarding more doctoral degrees in engineering than universities anywhere else. But the American Association of Engineering Societies said foreign nationals received 58 percent of the U.S. doctoral degrees in engineering last year: 3,766 degrees out of 6,504. A decade earlier, they accounted for less than half.

I doubt that US universities are awarding more doctoral degrees than others are. Even if that is true I doubt it will last for even 5 more years. You might measure this in various ways including: absolute number of doctoral degrees awarded or using a per capita number. I believe several European countries are ahead today on a per capita basis. On an absolute basis I would be surprised if China or India isn’t already ahead. But if neither is, that will not true for long. I tried to find some good data online and wasn’t able to find anything certain in the time I took. Lost Dominance in Ph.D. Production sites a National Bureau of Economic Research report:
