Software Strikes a Chord for Disabled Students

sparky3887 — Wed, 10 Mar 2010 02:25:02 +0000

Rensselaer Polytechnic Institute’s “Adaptive Use Musical Instruments for the Physically Challenged” program enables students with severe physical disabilities to make music by just moving their heads. The system uses a digital video camera to track a student’s head movements on a computer screen and then translates the movements into piano scales or drum beats. Zane Van Dusen, a RPI undergraduate student in computer science and electronic media arts and communication, developed the idea of using a digital video camera to track the user’s head. A cursor is digitally placed on a portion of the student’s head, usually the tip of the nose, to follow the user’s movements. As the cursor moves, sounds are created based on the user’s movements. Moving the head completely in one direction will create a scale climb on the piano or a quick series of drum beats or a drum roll. The project’s ultimate goal is to eventually enable students to compose their own pieces to help students learn the creative process and build communication skills. “The client or patient doesn’t have to be a musician to participate,” says the American Musical Therapy Association’s Al Bumanis. “The goal is not usually a performance, it’s increasing communication skills, understanding, relearning lost skills.”

Continued Growth in Science and Engineering Doctorate Production

sparky3887 — Wed, 10 Mar 2010 02:24:38 +0000

The number of doctorates awarded in science and engineering (S&E) fields has risen for the fourth consecutive year, according to the National Science Foundation. Last year the United States produced 29,854 doctorate degrees in S&E fields, an increase of nearly 7 percent from the previous year. Computer science doctorates led the way with a 28 percent increase to 1,452 degrees, following a double-digit increase in CS doctorates from the previous year. CS doctorates are up 79 percent since 2002 and now represent a considerable share of not only S&E doctorates but all doctorate degrees. Non-U.S. citizens have been key to the growth in CS doctorate degree production. In the mid-to-late 1990s permanent or temporary visa holders received about half of CS doctorates, but last year they accounted for 61 percent. CS doctorates to U.S. citizens rose 42 percent from 2002 to 2006, but jumped 115 percent for non-U.S. citizens over the same period.

New Grant Program Designed for ‘Transformative’ Computing Research

sparky3887 — Wed, 10 Mar 2010 02:24:07 +0000

The Cyber-Enabled Discovery and Innovation program will award $26 million in grants next year to support research into a wider range of uses for high-powered computing. Recipients will be called on to apply computational thinking to real-world problems involving engineering and computer science, as well as for biology, economics, and other social sciences. Sirin Tekinay, head of the National Science Foundation’s new program, says advanced computational thinking is about the process of sorting out data, deriving knowledge, gaining an understanding of complexity, and then developing new sociotechnical systems. All areas of science and engineering stand to benefit from this type of computing, which has helped clear the way for the decoding of the human genome, the production of complex real-time, satellite-aided maps, and the development of the Internet. For the program, innovation is defined as research that has the potential to produce transformative outcomes. Research institutions can apply for more than one grant, but a researcher cannot be named in more than two proposals during a competition cycle.

General Motors, Virginia Tech Scientists Collaborate to Advance Neuroinformatics

sparky3887 — Wed, 10 Mar 2010 02:23:41 +0000

Technological advancements in sensing technology makes it possible to take more accurate measurements of brain activity, something computer scientists and neuroscientists say could lead to the discovery of the complex neuronal networks in the brain that allow for simple, automatic movements such as reaching for a glass of water. Virginia Tech and General Motors Research are opening the Laboratory for Neuroinformatics for the purpose of creating algorithms that process the massive amounts of data neuroscientists collect from the brain. The lab will be co-directed by Virginia Tech computer science professor Naren Ramakrishnan and General Motors research scientist K.P. Unnikrishnan. “Neuroscientists are making the transition from studying neurons to studying networks–the sequences of firings and spikes of activity across big groups of neurons,” Ramakrishnan says. “What we are trying to do is analyze all this data and discover something about the network–the connections and relationships.” Unnikrishnan says the many possible applications of neuroscience-related research include analyzing data from cars and maintaining vehicle health. But even greater applications are possible, Unnikrishnan says. “Creation of brain-machine interfaces is the next frontier,” Unnikrishnan says. “Giving senses to people who have lost them–vision, touch, hearing, and motor–would be a contribution to humanity.”

20 Percent of Election Printouts Were Unreadable

sparky3887 — Wed, 10 Mar 2010 02:22:26 +0000

Recently discovered problems with the paper records produced by electronic voting machines in Cuyahoga Country, Ohio, could make a recount after next year’s presidential election a disaster. More than 20 percent of the paper printouts from touch-screen voting machines were found to be unreadable. The recount was necessary because the vote counting software crashed twice on election night and the margin of victory was one-half of one percent or less. Election workers found the unreadable ballots while conducting a recount of two races, which involved only 17 of the county’s 1,436 precincts. Board of Elections director Jane Platten says recounting the ballots for the entire county in the 2008 presidential election could take more than a week. Cuyahoga County uses Premier Elections Solutions (formerly Diebold) touch-screen voting machines that store votes on a memory card inside each machine. During the election a paper record of each vote is printed on a long reel of paper that is stored inside the machine. The paper record is used during recounts, but can be damaged or unreadable, usually because of a paper jam while printing. Premier Elections Solutions’ Chris Riggall says the company will investigate the situation.

Software That Learns From Users

sparky3887 — Wed, 10 Mar 2010 02:21:56 +0000

University of Washington computer science professor Pedro Domingos is developing CALO, a massive, four-year-old artificial intelligence project to help computers understand human intentions. The DARPA-funded project involves researchers from 25 universities and corporations focusing on many areas of artificial intelligence, including machine learning, natural-language processing, and Semantic Web technologies. CALO, which stands for “cognitive assistant that learns and organizes,” tries to help users by managing information about key people and projects, understanding and organizing information from meetings, and learning and automating routine tasks. For example, CALO can learn about projects and who is involved in those projects, so emails from those people can be given priority and categorized based on subject matter. CALO can also be used to make transcripts of meetings through voice recognition, or perform routine tasks such as purchasing books online, searching for a hotel that meets specific criteria, scheduling meetings, and coordinating people’s schedules. The ultimate goal is to build an artificial intelligence that can serve as a personal assistant that can learn about a user’s needs and preferences and adapt to them without having to be reprogrammed. “It’s an amazingly large thing, and it’s insanely ambitious,” Domingos says. “But if CALO succeeds, it’ll be quite a revolution.”

Data, Data Everywhere

sparky3887 — Wed, 10 Mar 2010 02:20:10 +0000

The explosion of digital information has brought with it major benefits as well as drawbacks, and among the latter is the paucity of storage space to house all that data and the increasing difficulty of guaranteeing data security and shielding privacy. Factors underlying the surfeit of information include technological innovations, coupled with plummeting prices for digital devices. The volume of digital information increases by a factor of 10 every five years, and Cisco projects that the amount of traffic streaming over the Internet annually will balloon to 667 exabytes by 2013. Accompanying the growth of data is the advent of data scientists, who combine the talents of software programmers, statisticians, and storytellers/artists to sift meaning out of the information deluge. Although the increasing digitization of the world is likely to bring advantages to all kinds of fields and industries via data aggregation and analysis, currently the data flood has greatly contributed to major problems such as the recent financial crisis, where it became apparent that banks and rating agencies were long reliant on models which, although they required a massive amount of data to be fed in, did not mirror actual financial risk.

Survey: Educators Aren’t Discussing STEM Careers With Students

sparky3887 — Wed, 10 Mar 2010 02:19:00 +0000

Science and math educators are keeping classes knowledgeable and interesting, but they are not promoting science, technology, engineering, and math (STEM) careers, according to most students surveyed by Harris Interactive for the American Society for Quality (ASQ). High school student respondents also say they do not think STEM knowledge is crucial to acquiring a good job. “We believe that as students get older and begin to diversify their studies and become more aware of the wide range of available career opportunities, they start to think that math and science aren’t necessarily critical to their job hunt,” says ASQ’s Maurice Ghysels. He says that teachers often leave out discussions of career options because of time and budget constraints. One of the challenges is that teachers themselves may have little knowledge of the wide variety of available STEM career options. Despite these drawbacks, there are ways to kindle interest in STEM careers among students, one of them being to offer hands-on lab activities and real-world examples of STEM applications at an earlier educational level such as elementary school.

Blue Ribbon Task Force Report: Preserving Our Digital Knowledge Base Must Be a Public Priority

sparky3887 — Wed, 10 Mar 2010 02:18:26 +0000

The Blue Ribbon Task Force on Sustainable Digital Preservation and Access recently released a report addressing the problem of ensuring that digital information will be accessible in the future. The report provides principles and actions to facilitate long-term economic sustainability and context-specific recommendations geared toward four specific scenarios–scholarly discourse, research data, commercially-owned cultural content (such as digital media), and collectively produced Web content such as personal Websites and blogs. “Valuable digital information spans the spectrum from official e-documents to some YouTube videos,” says Task Force co-chair Fran Berman. The report also cites four distinct prioritized courses of action–organizational action, technical action, public policy action, and education and public outreach action. The report concludes that preservation strategies need to develop at their own pace. “A key element of a robust sustainability strategy is to anticipate the effect of these changes and take steps to minimize the risk that long-term preservation goals will be impacted by short-term disruptions,” says Task Force co-chair Brian Lavoie.

Quantum on Quantum

sparky3887 — Wed, 10 Mar 2010 02:17:03 +0000

Researchers at Harvard University and Australia’s University of Queensland have designed and constructed a quantum computer capable of simulating and calculating the behavior of a molecular quantum system. The two photons that function as qubits in a quantum device are entangled, meaning that their states are linked and consistent over distance, thus augmenting the quantum computer’s ability to explore all possible solutions to a complex problem at once. The researchers tasked the computer with calculating the energy levels of the hydrogen molecule. Through simulation of the quantum forces inherent in the electrons of atomic bonds themselves, the computer’s photons accurately nailed the energy levels to within 6 parts per million. This milestone is “great, a proof of principle, more evidence that [a quantum computer] is not pie in the sky or cannot be built,” says University of California, Berkeley professor Birgitta Whaley.
