Textbook Firms Ink E-Deals For iPad – WSJ.com

Textbook Firms Ink E-Deals For iPad – WSJ.com.

Major textbook publishers have struck deals with software company ScrollMotion Inc. to adapt their textbooks for the electronic page, as the industry embraces a hope that digital devices such as Apple Inc.’s iPad will transform the classroom.

The publishers are tapping the know-how of ScrollMotion Inc. to develop textbook applications and test-prep and study guides for the iPad.

“People have been talking about the impact of technology on education for 25 years. It feels like it is really going to happen in 2010,” said Rik Kranenburg, group president of higher education for the education unit of McGraw-Hill Cos. and one of the publishers involved in the project.

Other publishers include Houghton Mifflin Harcourt K-12, which is a unit of Education Media & Publishing Group Ltd.; Pearson PLC’s Pearson Education, and Washington Post Co.’s Kaplan Inc., known for its test-prep and study guides.

Many developers and publishers are working on applications that will work on the iPad and other digital devices. Publishers have been investing heavily in digital education in recent years.

Compass Intelligence, a market research firm in Scottsdale, Ariz., estimates that technology spending in the U.S. educational market could grow to $61.9 billion in 2013, from $47.6 billion in 2008.

So far, digital education has largely been confined to desktops and laptops, but many college students have been slow to embrace e-textbooks on their computers. Portability could make the difference, however.

Maureen McMahon, president of Kaplan Publishing, said a recent Kaplan study showed that students remain big fans of printed books but that they would be more receptive to e-textbooks on portable digital devices.

Whether the iPad will be the digital device to transform the classroom remains to be seen. “Nobody knows what device will take off, or which ‘killer app’ will drive student adaptations. Today they aren’t reading e-textbooks on their laptops. But ahead we see all kinds of new instruction materials,” said Mr. Kranenburg.

Though Apple didn’t outline its strategy to target the educational sector with its iPad last week, people familiar with Apple’s thinking have said that the iPad’s use in schools was one of the focal points of discussions in developing the product. In its exploration of electronic book technology, it thought particularly about how it could re-invent textbooks, these people said. Apple declined to comment on the role of textbooks on the iPad. Apple has an edge in the educational sector becauseits Macintosh computers have always enjoyed a strong following in the academic sphere, and it already offers educational audio and video content through its iTunes U service.

The iPad also will be helped by the interest that schools have always had in tablet-form computers. Science teachers, for example, could use them for taking lab notes, which often use a combination of sentences, charts and mathematical equations, while others could use them on field trips. “This is the beginning of handheld education,” said John Lema, chief executive of ScrollMotion.

But the iPad faces competition from other devices, notably the cheap portable laptop computers known as “netbooks” that can be purchased for a couple hundred dollars, and that have already started making in-roads in schools. Amazon Inc., which initially failed in its attempt to pitch its bigger-sized Kindle DX to schools, says it has plans to offer “active content” that works more like programs and less like plain books.

Jeanne Hayes, an educational consultant in Littleton, Colo., said the iPad’s lower-than-expected entry-level price of $499 will interest schools, but some of them may not be able to purchase the device right away if they’ve already purchased netbooks.

“It will be a matter of how Apple represents this to schools and how they fold it into their offerings,” said Ms. Hayes.

It’s also unclear whether ScrollMotion will emerge as the leading applications provider, with many others in the works. A closely held New York-based firm, ScrollMotion has already developed applications for Apple’s iPhone and iPod Touch. ScrollMotion takes digital files provided by publishers for the iPad, adapts them to fit on the device, and then adds enhancements such as a search function, dictionaries, glossaries, interactive quizzes and page numbers.

The features of its iPad deal with publishers include applications to let students play video, highlight text, record lectures, take printed notes, search the text, and participate in interactive quizzes to test how much they’ve learned and where they may need more work.

Tegra 250 sets mobile speed record

source

  • second-generation Tegra processor has been sampling since 3Q09 and is expected to reach production in 2Q10
  • contains two Cortex-A9 CPUs, each running at up to 1.0GHz.
  • should score 5760 on the Coremark test (using two threads)
    • more than twice the speed of the iPhone 3GS, Nexus One, or any other smartphone shipping today
    • 40% faster than the Coremark score of the 1.6GHz Atom CPU (also using two threads with hyperthreading).
  • exceeds 1.0W at full speed from both cores
    • 150mW for HD (720p) video playback and just 15mW for audio playback –> similar to original Tegra
  • can decode video at 30fps and full HD (1080p) resolution for H.264 base and main profile
    • restricted to 720p for the ultrachallenging H.264 high profile (Blu-ray)
    • can also encode video at 1080p for H.264 base profile.
    • Few other mobile processors can handle 1080p video at even the base profile.
  • 3D performance : peak speed of 90 million triangles per second.
  • will appear initially in tablet computers and similar-sized devices that will debut by mid-2010.
    • smartphones will not ship until late 2010
  • third-generation processor expects to sample before the end of this year

Nano-injection; NGL to make 0.039um2 bitcell for 16nm

  • 나노 인젝션(NanoInjection)이라는 새로운 리소그래피 기술을 이용한다. 이는 가스를 불어 넣는 지점에 전자 빔을 대서 패턴을 그리는방법이다(그림6(b)).
  • 나노 인젝션의 이점은 기존의 전자 빔 리소그래피 기술과는 달리 포토 레지스트가 필요 없다는 점이다. 포토 레지스트를 쓰지 않아도 되기 때문에 리소그래피의 해상도를 높이기 쉽고, 결과적으로 미세한 패턴을 형성할 수 있게 되는 것이다.
  • 하지만 단점도 있다. 기존의 전자 빔 기술 등과 마찬가지로 생산성이 낮다는 것이다. 앞으로 생산성 향상을 위한 연구개발이 진행될 것으로 보인다.
  • Nano injection lithography eliminates the masks of other lithography techniques. Eliminating the masks and the photoresist cuts the patterning process from five steps to one, greatly simplifying production.
  • A new type of lithography, which uses an electron beam to spark a chemical reaction, could provide a cheaper way to build the incredibly tiny transistors that the chipmaking industry will require in a few years.
  • Researchers from Taiwan and the University of California, Berkeley, say they’ve made static random access memory (SRAM) that anticipates 16-nanometer chip features with a new process called nano injection lithography.
  • They say their technique may provide an alternative to lithography that relies on extreme ultraviolet light (EUV), which still is beset by problems and could be extremely expensive.
  • a metallorganic gas, an organic molecule studded with atoms of platinum.
  • An electron beam with a diameter of 4.6 nm is fired at the gas, causing a chemical reaction that deposits the platinum on the silicon chip in the desired pattern, while the rest of the gas flows away.
  • With this hard mask deposited on the silicon, the researchers then use chemicals to etch away exposed silicon and thereby create the desired circuits. The platinum mask is then chemically removed.
