Britain Leading London 2012 Technology Race
Times Online (UK) (09/08/08) Slot, Owen
At the recent Summer Olympics in Beijing, Great Britain outfitted its
athletes with advanced skinsuits, canoe paddles, and meteorological
equipment for sailors. Britain is planning more technological advancements
for the next Olympics, including radar tracking for archery, a judo robot,
personalized spikes for sprinters, and a miniaturized wireless body sensor
to help swimmers improve their tumble turns. U.K. Sport head of research
and development Scott Drawer says such advancements are only the beginning.
"In 2012 I want to have the most aerodynamic or hydrodynamic teams across
all sports, who have the best equipment with the least drag and the
strongest, lightest components--who can look across the start line and know
that they are in a better position than anyone else," Drawer says. Perhaps
the single greatest technical innovation planned for the London Olympics is
a wireless sensor, slightly larger than a fingernail, that can sit behind
the ear of an athlete and send information to a coach on speed, stride
frequency, and stride length. Drawer says most coaches obtain this
information by eye, but by having objective information, better
instructions can be given. The e-AR sensor, developed at Imperial College,
London, is still in testing, but should be applicable to a variety of
sports, including running, gymnastics, and swimming.

Protecting Your Vote With Invisible Ink
Discover (09/04/08) Lafsky, Melissa
Transparency of the entire voting system has never been more important,
and each voter should be able to verify that his or her vote is protected
and correctly recorded in the final tally. The challenge is revealing the
secret ballot process without sacrificing the privacy that democracy relies
on. Computer scientists, lead by cryptographer David Chaum, say they have
found a solution that uses invisible ink to protect voter confidentiality.
The Scantegrity II (invisible ink) system, was unveiled at the
USENIX/ACCURATE Electronic Voting Technology Workshop. The system uses a
regular pen and a special decoder pen for use on a ballot that looks like a
normal fill-in-the-dot ballot. Voters make their selections by marking the
bubble next to their candidate of choice with the decoder pen. A two- or
three-letter code will appear in the bubble. The ballots' serial numbers,
as well as the invisible codes, have all been created and recorded by
voting officials before the election to eliminate the possibility of ballot
stuffing. Voters can record their ballots' serial numbers and codes to
verify their vote was counted. The ballot is then scanned through an
optical scanner. Chaum says that even if only one or two percent of voters
go online to check their receipts, it will create a 95 percent chance that
no fraud occurred.

Keep Streaming Videos, the Tubes Are Fine: Report
Finds
Wired News (09/03/08) Singel, Ryan
Although some experts have been concerned that surging Internet data
traffic could soon overwhelm the underlying infrastructure, new research
from TeleGeography found international Internet bandwidth jumped 62 percent
in the past year, while Internet traffic grew only 53 percent and filled
only 43 percent of the Internet's capacity at peak times. The study found
that Latin America and South Asia both doubled the capacity of their
backbones in the past 12 months. Meanwhile, the cost of sending and
receiving data continues to decline. The report says the cheapest
wholesale prices for data transmission are in Europe and North America,
where capacity is abundant. Data on the Internet's size, capacity, and
links are difficult to find, since almost all of the Internet's
infrastructure is privately owned, and there is little incentive and few
requirements to share data with the government or with researchers.
TeleGeography says it gathers data at Internet exchange points around the
world and from surveys. The firm expects "strong growth and falling
prices" to continue into the future.

Driving the Future of In-Vehicle ICT
ICT Results (09/05/08)
The HUMANIST project is working to integrate Europe's expertise in the
field of intelligent transport systems (ITSs) to make driving easier and
safer. Four years ago, European competence in ITS human-machine
interaction was scattered throughout various countries and research
institutes. The HUMANIST project started building bridges between these
pockets of knowledge, and now researchers can access the expertise of
others in the network to enhance the quality, safety, and convenience of
ITS systems and services, says HUMANIST coordinator Jean-Pierre Medevielle.
Rapid advancements in in-vehicle driver information systems (IVISs) and
advanced driver assistance systems (ADASs) are changing how we drive, but
continued progress hinges on understanding how people interact with the
technology and applying this information to IVIS and ADAS technology.
Promoting the human-centric approach was a key issue for the HUMANIST
project. ITS is being applied to traffic and transportation management,
IVIS, advanced driver assistance systems, and traveler and traffic
information services. Despite advances in ITS, questions surround how such
developments will impact drivers as technology takes over tasks
traditionally controlled by them. The HUMANIST project is working to
understand how ITS affects a driver's behavior, and has organized several
conferences and workshops on the subject.

Taking Intelligence Analysis to the Virtual World
Federal Computer Week (09/04/08) Bain, Ben
The Office of the Director of National Intelligence (ODNI) is increasingly
monitoring online virtual worlds for use in intelligence analysis. ODNI's
Intelligence Advanced Research Projects Activity (IARPA) program is
launching the Analysis WorkSpace for Exploration project to explore how
virtual worlds can be used to create a workspace for future analysis. In a
separate effort, through ODNI's Summer Hard Problem (SHARP) program, about
30 people spent the summer studying virtual worlds. IRAPA, which focuses
on high-risk/high-reward research, held an industry day in July on
A-SpaceX, a project that develops virtual worlds to explore how
manipulating time frames and mapping decision processes can improve
intelligence analysis. During the first phase of the project, which will
last about 18 months, officials plan to create a Time Machine virtual world
to explore how changes in chronology can affect analysis. Officials also
plan to use virtual words to create MindSnaps that will allow analysts to
track and map out decision processes in a virtual world. IARPA Knowledge
Discovery and Dissemination project manager Arthur Becker says the agency
is focused on research that generally yields results in three to five
years. The Knowledge Discovery and Dissemination project will explore how
information technology can be used to manage the large amounts of
information analysts typically receive. Another IARPA project will reduce
costs by making computer code more easily available to developers, Becker
says.

Cornell Gets $10 Million Federal Grant to Establish New
Institute Applying Computing to Sustainability
Cornell University (09/03/08) Steele, Bill
Cornell University's new Institute for Computational Sustainability will
use a $10 million National Science Foundation grant to pursue far-reaching
research agendas that promise significant advances in computing that will
greatly benefit society. "Our vision is that computing and information
science can--and should--play a key role in increasing the efficiency and
effectiveness of the way we manage and allocate our natural resources,"
says Cornell professor and institute director Carla Gomes. She says that
many of today's problems in ecology and conservation involve juggling large
numbers of variables and finding the best way to balance those variables.
Some problems are so complex that they will require significant
advancements in computer science, researchers say. Gomes says the
institute will create a new field of computational sustainability, similar
to computational biology, which will stimulate developments in the computer
science areas of constraint optimization, dynamical systems, and machine
learning. The institute will work with the Cornell Center for a
Sustainable Future and a variety of other sustainability programs on
campus, but Gomes says the institute's goal is to extend beyond the initial
members of the institute, and to help organizations with computational
problems that could benefit other fields.

Massive $208 Million Petascale Computer Gets Green
Light
Network World (09/02/08)
The University of Illinois at Urbana-Champaign's National Center for
Supercomputing Applications has finalized a contract with IBM to build Blue
Waters, a 200,000-processor supercomputer that will provide a sustained
performance of more than 1 petaflop. The 200,000 processors will be paired
with more than a petabyte of memory and more than 10 petabytes of disk
storage. The memory and storage will be made globally addressable so the
processors will be able to share data from a single pool exceptionally
quickly. The new supercomputer, which will go online in 2011, is supported
by a $208 million National Science Foundation (NSF) grant. Blue Waters
will be based on Productive, Easy-to-use, Reliable Computing System
technology. NSF says the system may be used to study complex processes
such as the interaction of the Sun's coronal mass ejections with the
Earth's magnetosphere and ionosphere, the formation and evolutions of
galaxies in the early universe, understanding the chains of reactions that
occur with living cells, and the design of novel materials. NSF says that
by 2010 or 2011, academic researchers will be able to access numerous
high-performance systems that provide sustained performance between 10
teraflops and 2 petaflops for a variety science and engineering projects
that are integrated into a national cyberinfrastructure environment and
supported at a national, regional, or campus level.

Toshiba Shows Advanced Image Detection Prototypes
IDG News Service (08/30/08) Williams, Martyn
Toshiba has developed gesture control technology that could potentially
enable people to control a TV with the movement of their hands. The
gesture control system is designed to track the person in its field of
view, and a cursor appears on the TV screen to mirror the way the
individual has waved his or her fist around, as if controlling a mouse.
The gesture control prototype was just one of several image-detection
systems from Toshiba that were on display at this week's IFA electronics
show in Berlin. Toshiba's new Qosmio laptops make use of an earlier
version of the gesture control system to enable users to move the cursor on
their screen with their fist and to perform a mouse click by raising a
thumb. "The major difference with the Qosmio is that it's just smoother
and more advanced tracking technology," says Kate Knill, manager of
interaction technology at Toshiba's laboratory in Cambridge. Toshiba also
has developed a pattern-recognition system that would work with a video
camera mounted above a TV screen to recognize viewers, and Knill says it
could be potentially used to provide personalized information or switch to
a favorite channel when they enter the room.

Stanford's 'Autonomous' Helicopters Teach Themselves to
Fly
Stanford University (08/29/08) Stober, Dan
Stanford University computer scientists have developed an artificial
intelligence (AI) system that enables robotic helicopters to teach
themselves how to fly and perform difficult stunts by watching other
helicopters perform the same maneuvers. Professor Andrew Ng says the
stunts are by far the most complex aerobatic maneuvers flown by any
computer-controlled helicopter. The helicopters learned how to perform the
stunts by watching a helicopter controlled by expert radio control pilot
Garett Oku. After observing the human-controlled helicopter, the
AI-controlled helicopter performed a variety of stunts on its own. The air
show is an important demonstration in "apprenticeship learning," in which
robots learn by observing an expert instead of having software engineers
attempt to write the instructions from scratch. "I think the range of
maneuvers they can do is by far the largest," says Georgia Institute of
Technology professor Eric Feron. "But what's more impressive is the
technology that underlies this work." To teach the helicopter to fly, the
researchers had Oku and other pilots fly entire air show routines while
recording the movements of the helicopter. As maneuvers were repeated
several times, the trajectory of the helicopter varied slightly with each
flight, but the learning algorithms were able to discern the ideal
trajectory the pilot was seeking, enabling the autonomous helicopter to
learn to fly the same routine better and more consistently than the human
pilots. During autonomous flight, a ground-based computer processes the
data, makes quick calculations, and sends new instructions back to the
helicopter 20 times per second.

How a Global Internet Policy Might Look
InternetNews.com (08/27/08) Corbin, Kenneth
The ideal vision of a global Internet policy was laid out by leading
Internet activists attending the second annual Internet Governance Forum,
who were surveyed by researchers from the Pew Internet and American Life
Project and Elon University. Sixty-six percent of respondents called for a
global Internet bill of rights, whose fundamental principles would include
freedom of information and freedom of expression. The poll indicated that
the leading challenge policy makers have to wrestle with is the digital
divide, or uneven Internet access. Many respondents said the funding
needed to erase the digital divide should come from strong competition
between private access providers to lower prices, while others said that
each nation's government should fund its communications infrastructure, or
create a global fund where commercial providers pool their resources.
Forty-seven percent of respondents described the Internet's control as
decentralized, while 65 percent of those who took the opposite view said
the United States formed the Internet's core. Forty-five percent concurred
that ICANN "is not effective and should be placed in a more neutral, global
control structure." The poll signaled a widespread conviction that the
Internet fuels global economic expansion, while many respondents objected
to broadband providers' monopoly in an excessive number of markets.
Respondents also said that security must adapt to tackle lingering dangers
such as child pornography and spam.

Textured Graphics Can Be Captured in a Flash
New Scientist (08/27/08) Barras, Colin
Researchers from the University of Manchester in the United Kingdom have
developed a new technique for making more realistic textures for the
virtual worlds of computer games. The process involves taking two photos
of textured surfaces. Working with Gregory Ward at Dolby Canada in
Vancouver, the team took a photo with flash to prevent protruding surface
parts from appearing brighter than parts in cracks and pits, which enabled
the researchers to record the true color of every part of the surface. The
researchers also took another photo without extra lighting, then used
software to compare the brightness of every matching pair of pixels in the
two images and to calculate how much of the brightness is due to its
position and color. They were able to produce a realistic rendering of a
surface's texture using the information. The team presented its results at
the ACM SIGGRAPH conference in Los Angeles.

Data Centers: Focusing on Sustainability
Dr. Dobb's Journal (08/27/08)
Dallas Thornton, director of Cyberinfrastructure Services for the San
Diego Supercomputer Center at the University of California, San Diego, says
in an interview that the center will move to a new facility that uses "a
natural hybrid ventilation system" that employs unaltered external and
internal air to supply adequate temperature and humidity to the building
over 95 percent of the time. Thornton estimates that U.S. data center
loads devour more than 1.5 percent of the national power supply, and notes
that federal and state governments, along with many power companies, are
offering incentives for more efficient IT practices and deployments. To
identify and leverage these opportunities, Thornton recommends that
companies more deeply meld data center facilities personnel to their IT
operations. "Virtualization of services, servers, and storage provide
opportunities for sharing unused resources and reducing the IT equipment
and power needed," says Thornton, who adds that many of the
virtualization-enabling software and hardware technologies also provide
features that streamline tough jobs and offer previously unavailable
redundancy options to IT administrators. The advent of cross-site
virtualization and greater ubiquitous data access will affect augmented
service-level redundancy and availability that will reduce the need to
implement expensive and power-consumptive local uninterruptable power
supply systems, generators, and redundant power distribution throughout
each center, saving millions of dollars in facilities costs and 10 percent
to 30 percent in ongoing energy consumption at each site, Thornton says.
He observes that along with the growing prevalence of technology in
people's daily lives is the mounting challenge of the underlying
infrastructure being taken for granted. He believes that
cyberinfrastructure "should become as accessible and reliable as the power
that comes from your local utility company."

Robotics Engineer Seeks to Define Individuality
Nikkei Weekly (08/25/08) Vol. 46, No. 2351, P. 31; Tamura, Hiroshi
Robotics engineer and Osaka University professor Hiroshi Ishiguro's
interest in what defines human individuality informs his research, which
includes a lifelike android of himself whose subtle mimicry illustrates the
point that one's self image can be distinct from what is seen by those
around them. "The most important thing only a human can do is think about
the fundamental questions in this world," Ishiguro says. "Responding to
these questions is the only situation in which people truly behave like
human beings. The only people who deserve to be called individuals are
those who ask what human beings are and establish solid perspectives and
base their lives on them." Ishiguro says the more study he devotes to this
observation, the more complicated it becomes to realize his dream of
creating an android that cannot be distinguished from a human being. This
is due to human beings' complexity and the difficulty of understanding
them. Ishiguro says that pinning down individuality requires learning the
fundamentals of philosophy and cognitive science.

Every Move You Make
Economist (08/20/08)
Workers that maintain a rhythm to their day are more productive than
arrhythmic colleagues, even when part of their rhythmic day is spent on
non-work-related tasks, concludes a recent Massachusetts Institute of
Technology (MIT) study. For the study, MIT researchers Benjamin Waber and
Sandy Pentalnd used electronic identity badges that monitored a wearer's
movements and interactions on a second-by-second basis. Each badge
contained motion sensors, a microphone, a microprocessor, and a radio
transceiver that enabled it to sense and broadcast a signal to a base
station. The badge recorded whether the wearer was walking, their body
movements when stationary, the timbre and inflection of the wearer's voice,
who the wearer talked to if the other person also wore a badge, and the
length of any conversations the wearer had. The gathered information, when
combined with data on productivity, provided insights on which work habits
are the most effective and created a picture of which social networks are
of the most value to a company. The study found that the more people the
wearer knew at their office, and the more they interacted with them, the
more productive they were. Even non-work-related, social conversations
improved employee efficiency, indicating that small increases in social
cohesiveness can lead to significant improvements in productivity.

XML Retrieval and the Mind-Reading Machines
Information Today (08/08) Vol. 25, No. 7, P. 20; Hawkins, Donald T.
Charles Clarke of Ontario's University of Waterloo says that his primary
concentration has been documents and how their structure and content is
represented rather than specific XML technology. "I am more interested in
information access, and XML is really the tool that has become a common
language for expressing this interesting and rich structure, metadata, and
content, which I think is the real focus of the document," he says. Clarke
says that the basic concept of XML for marking up documents with tags and
expressing data in a structured manner will endure for quite a while. He
says that his ideal vision of a retrieval mechanism is something that
retrieves only the part of the document he needs rather than the entire
document. Clarke also mentions the need for a precise query language that
allows users to particularize the right document portion. He refers to
Google's progress in developing a "mind-reading" Web search engine, noting
that "for many queries, the algorithms are trying effectively to understand
what you really mean and give that to you. Or they may make a good guess
at what you probably mean, based on the aggregate behavior of millions of
people."
