  • The steady improvements to the electric distribution systems have been joined by new concepts that include generation, conservation and storage of electricity, part of the Energy Policy Act dictated by Congress in 2005. The act recognizes changes in factors affecting the generation of electric energy and now includes the field of its distribution. These include increasing concerns for the environment (global warming, etc.)

  • FeedTree aware client applications should be able to examine conventional RSS feed data to discover if up- dates to that feed will be published through FeedTree. To do this, FeedTree metadata can be added to the RSS document structure to signal that it is available for sub- scription in the overlay. In this way, a FeedTree appli- cation bootstraps the subscription process with a one- time HTTP request of the conventional feed. All future updates are distributed through incremental RSS items published in FeedTree.

  • Building upon the FeedTree distribution system, we foresee a potential for entirely new services based on RSS which cannot be accomplished today. By using single-writer logs [18] in combination with a distributed storage mechanism such as a DHT [22, 15, 9], we can record permanently every RSS item published, allowing a distributed archival store of micronews across the In- ternet. Clients of such a system would easily be able to find out what they “missed” if they had been offline for so long that old RSS items are no longer available in any conventional, static RSS feed.

  • Introduction: Today, the energy supply is primarily based on the combustion of fossil fuels. Electricity generation is the main driver for carbon dioxide emissions in stationary applications, whereas vehicles powered by internal combustion engines are a major source of distributed carbon dioxide emissions. The generation of electricity from renewable energy sources such as solar power, wind power, tidal power, or the use of biomass is reducing the burden from carbon dioxide emissions.

  • Ethernet-based data services offer the opportunity to create differentiation, command premium pricing, and earn higher margin for such value-added data services as transparent LANs, storage area networks, and virtual private networks. Extending native 10/100Base-T and Gigabit Ethernet services across the LAN, WAN, and MAN means data services are less expensive to deploy, provision quickly, and offer exceptional reliability and security.
