Vortex Induced Vibrations (VIV) result from vortices forming and shedding on the downstream side of a bluff body in a current. Vortex shedding alternates from one side to the other, thereby creating a vibration or oscillation. The VIV phenomenon is non-linear, which means it can produce useful energy at high efficiency over a wide range of current speeds.

VIVACE stands for Vortex Induced Vibrations for Aquatic Clean Energy. It doesn't depend on waves, tides, turbines or dams. It's a unique hydrokinetic energy system that relies on "vortex induced vibrations." Vortex induced vibrations are undulations that a rounded or cylinder-shaped object makes in a flow of fluid, which can be air or water. The presence of the object puts kinks in the current's speed as it skims by. This causes eddies, or vortices, to form in a pattern on opposite sides of the object. The vortices push and pull the object up and down or left and right, perpendicular to the current.

CERES and National Biological Information Infrastructure (NBII) Biological Resources Division (BRD) are collaborating on the development of an Integrated Environmental Thesaurus and Thesaurus Networking Tool Set for Metadata Development and Keyword Searching.

SWEET ontologies are written in the OWL ontology language

Europeana - the European digital library, museum and archive - is a 2-year project that began in July 2007. It will produce a prototype website giving users direct access to some 2 million digital objects, including film material, photos, paintings, sounds, maps, manuscripts, books, newspapers and archival papers. The prototype will be launched in November 2008 by Viviane Reding, European Commissioner for Information Society and Media.

The SOE's combination of gestural i/o, recombinant networking, and real-world pixels brings the first major step in computer interface since 1984; starting today, g-speak will fundamentally change the way people use machines at work, in the living room, in conference rooms, in vehicles. The g-speak platform is a complete application development and execution environment that redresses the dire constriction of human intent imposed by traditional GUIs. Its idiom of spatial immediacy and information responsive to real-world geometry enables a necessary new kind of work: data-intensive, embodied, real-time, predicated on universal human expertise.

This article is a guide for collection developers at the point of considering a metadata schema for their digital collection. The nine questions asked in this article will assist a developer in clarifying how he wants the collection to be organized, described, and used. This article uses examples to illustrate how these questions guided the development of a digital collection built at the University of Southern California.

Zenbe is free email that works with the email you already use. Zenbe offers many features, including email, online calendar, lists, mobile sync, file sharing, team collaboration. It even works with Facebook and Twitter.

E-mail is no longer just e-mail, and it arguably hasn't been for some time. Webmail clients like Yahoo's have offered IM and calendar integration for a while, and now Gmail allows video chatting and embedded gadgets. Zenbe, a new startup, is bringing social features, collaboration, and a new perspective on our e-mail routine with things like a sharable wiki, discussions, and even a Twitter sidebar.

It is now recognised that the developed world is struggling to meet its carbon-reduction targets, while emissions by China and India have soared. Meanwhile, signs suggest that the climate is even more sensitive to atmospheric CO2 levels than was previously thought.

Ocean Thermal Energy Conversion (OTEC), a clean, renewable energy source that has the potential to free many economies from their dependence on oil.

Reduced to its essence, China and other developing nations want infusions of both capital and technology from the developed world to help them cut emissions.

Our "pattern language" is a holistic collection of "patterns" that can be used together to address an information or communication problem. Each "pattern" in this pattern language, when complete, will represent an important insight that will help contribute to a communication revolution.

One of the highlights of October's Web 2.0 Summit in San Francisco was the emergence of 'Semantic Apps' as a force. Note that we're not necessarily talking about ...

The report, "SMART 2020: Enabling the Low Carbon Economy in the Information Age," was developed by The Climate Group in partnership with the Global e-Sustainbility Initiative (GeSI), and looks at how information technology can play a positive role in fighting climate change.
