59 MPG Toyota iQ On Sale In Europe, US Plans Unclear
I own some Toyota stock (and bought a bit more recently) based on their excellent management and production system and the results they have achieved (so I pay attention to what they are doing - plus I own them because they do things I see as wise so it is a self reinforcing dynamic). Business week recently wrote about Ford’s 65 mpg Diesel Car the U.S. Can’t Have.
I owned Ford stock back when they were adopting Deming based management principles but when they dropped those to pursue short sighted goals and poor management practices I sold and bought Toyota (turned out to be a very wise decision - my mistake was holding Ford too long hoping they would realize their mistake).

Kenji Hiranabe talks about Toyota’s development process (webcast). Kenji shares a presentation he attended earlier this year by Nobuaki Katayama, a former Chief Engineer at Toyota, and the lessons he learned from him.
The webcast takes awhile to get going. If you are impatient you might want to start at the 6 minute mark. Some thoughts from the talk:
The webcast includes a nice (though short) discussion of agile management in software development and lean manufacturing (the different situation of manufacturing versus software development). Kenji Hiranabe has also translated several agile and lean books into Japanese including Implementing Lean Software Development.

The annual ranking of research Universities are available from Shanghai’s Jiao Tong University. The methodology values publications and faculty awards which provides a better ranking of research (rather than teaching). Results from the 2008 rankings of Top 500 Universities worldwide, country representation of the top schools:
| location | Top 100 | % of World Population |
% of World GDP | % of top 500 |
|---|---|---|---|---|
| USA | 54 | 4.6% | 27.2% | 31.6% |
| United Kingdom | 11 | 0.9 | 4.9 | 8.3 |
| Germany | 6 | 1.3 | 6.0 | 8.0 |
| Japan | 4 | 2.0 | 9.0 | 6.2 |
| Canada | 4 | 0.5 | 2.6 | 4.2 |
| Sweden | 4 | 0.1 | 0.8 | 2.2 |
| France | 3 | 0.8 | 4.6 | 4.6 |
| Switzerland | 3 | 0.1 | 0.8 | 1.6 |
| Australia | 3 | 0.3 | 1.6 | 3.0 |
| Netherlands | 2 | 0.2 | 1.4 | 2.4 |
| Denmark | 2 | 0.1 | 0.6 | 0.8 |
| Finland | 1 | 0.1 | 0.4 | 1.2 |
| Norway | 1 | 0.1 | 0.7 | 0.8 |
| Israel | 1 | 0.1 | 0.3 | 1.2 |
| Russia | 1 | 2.2 | 2.0 | 0.4 |
| China | 20.5 | 6.6 | 6.0 | |
| India | 17.0 | 1.9 | 0.4 |
There is little change in most of the data from last year, which I think is a good sign, it wouldn’t make much sense to have radical shifts over a year in these rankings. Japan lost 2 schools in the top 100, France lost 1. Denmark (Aarhus University) and Australia (University of Sydney) gained 1. Last year there was a tie so there were 101 schools in the top 100.
The most dramatic data I noticed is China’s number of top 500 schools went from 14 to 30, which made me a bit skeptical of what caused that quick change. Looking more closely last year they reported the China top 500 totals as (China 14, China-Taiwan 6 and China-Hong Kong 5). That still gives them an impressive gain of 5 schools.
Singapore has 1 in the 102-151 range. Taiwan has 1 ranked in the 152-200 range, as do Mexico, Korea and Brazil. China has 9 in the 201-302 range (including 3 in Hong Kong). India has 2 in the 303-401 range.

Surprise, surprise: U.S. broadband is slow. Really slow.
Japan dominates international broadband speed with a median download speed of approximately 63 Mb/s, more than enough to stream DVD-quality video with surround audio in real time. Next on the list is South Korea where download speeds achieve an average of 49.50 Mb/s. Finland and France follow with 21.70 Mb/s and 17.60 Mb/s, respectively. Canada ranked eighth with an average download speed of 7.60 Mb/s. The U.S. came in 15th with 2.35 Mb/s.
I see this as an economic issue. Countries that have provided an investment in internet infrastructure to provide broadband to the home at reasonable prices will be rewarded.

Toyota has a long term vision. The population of Japan is aging rapidly. Toyota has invested in personal transportation and personal robotic assistance for quite some time. I must admit this new Winglet doesn’t seem like an incredible breakthrough to me (their earlier iUnit seems much better to me - though I am sure much more expensive too). The interest to me is in their continued focus on this market which I think is a smart move. The aging population worldwide (and others) will benefit greatly from improved personal mechanical assistance.
The Winglet is one of Toyota’s people-assisting Toyota Partner Robots. Designed to contribute to society by helping people enjoy a safe and fully mobile life, the Winglet is a compact next-generation everyday transport tool that offers advanced ease of use and expands the user’s range of mobility.
The Winglet consists of a body that houses an electric motor, two wheels and internal sensors that constantly monitor the user’s position and make adjustments in power to ensure stability. Meanwhile, a unique parallel link mechanism allows the rider to go forward, backward and turn simply by shifting body weight, making the vehicle safe and useful even in tight spaces or crowded environments.
Toyota plans various technical and consumer trials to gain feedback during the Winglet’s lead-up to practical use. Practical tests of its utility as a mobility tool are planned to begin in Autumn 2008 at Central Japan International Airport (Centrair) near Nagoya, and Laguna Gamagori, a seaside marine resort complex in Aichi Prefecture. Testing of its usefulness in crowded and other conditions, and how non-users react to the device, is to be carried out in 2009 at the Tressa Yokohama shopping complex in Yokohama City.
Toyota is pursuing sustainability in research and development, manufacturing and social contribution as part of its concept to realize “sustainability in three areas” and to help contribute to the health and comfort of future society. Toyota Partner Robot development is being carried out with this in mind and applies Toyota’s approach to monozukuri (”making things”), which includes its mobility, production and other technologies.
Toyota aims to realize the practical use of Toyota Partner Robots in the early 2010s.
On a personal note, I bought some more Toyota stock last week. The stock has declined a bit recently. Toyota is one of the companies in my 12 stocks for 10 years portfolio.

Inside Honda’s brain by Alex Taylor III
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.

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.
Country representation of the top universities (number of top schools in each country):

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…)
Shanghai’s Jiao Tong University produces a ranking of the top universities annually (since 2003). The methodology used focuses on research (publications) and faculty quality (Fields and Nobel awards and citations).
