POV title date October 2011 RDFfeed refers to data feed in Resource Description Framework RDF and maybe a little bit of Web Ontology Language OWL format. RDF is an emerging semantic web standard language ideal for describing real world objects, and the resulted RDF data resources can be consumed by computers i.e. machine readable . Theoretically, every web site can create RDF resources for all the information on the web site and make them available as RDF feeds. Any other web sites, if interested, can then acquire the data from the RDF feeds and integrate them with other data obtained in the same fashion. This so called web of data or semantic web will open doors to a great number of new services that are not possible today. Of course, this sounds just like a dream. But, lots of people are working hard to make it a reality. W3C is leading the way followed by a large number of volunteers. For example, web2express.org launched a free online data feed service in October 2007 for anyone to create RDF feeds and RDF data resources. Examples http web.resource.org rss 1.0 spec RSS 1.0 feeds for news or blogs. http web2express.org ufeed RDF feeds for products, news, events, jobs, and studies. Free or open source tools services http www.w3.org RDF Validator W3C RDF validation http www.web2express.org ufeed Ufeed A free online tool for publishing data resources and data feeds in RDF, including product information, news, events, jobs and studies.

Concept File Processdiagram RDFPowerstation.jpg thumb Process diagram of the RDF Powerstation File Processdiagram RDFPowerstation Fluegas.jpg thumb Process diagram of the fluegas purification unit The RDF Powerstation is directly integrated in a building like a business centre and is used as a cogeneration or trigeneration plant. Due to that the incineration unit and all additional components, which are necessary for the operation of the plant and the utilization of the energy, are located in the consumers area. So the energy is produced and used at the same place. The technical realization of this concept is based on the configuration of the process diagram. Before the crude materials e.g. municipal or commercial waste are introduced into the incineration unit, these resources are mechanically treated at an external station. The treatment intensity is significantly linked to the quality and composition of the primary material. So the treatment process can be very different from an ordinary crushing and a rough sortation to a multistep milling process with various product streams and a finishing briquetting. The final product of this step the Refuse derived fuel is used in the RDF Powerstation . The combustion unit is equipped with a water cooled reciprocating grate, a post combustion chamber, where the selective non catalytic reduction of the nitrogen oxides is included and a steam boiler with the heat exchangers. The main part of the heat energy, which is captured in the live steam, is used for the electricity production. Another portion is applied for a heating grid or an absorption refrigerator. Following the steam boiler the flue gas enters the 4 stage dry scrubber. There the pollutants of the flue gas are extracted by different additives, which ... more details

Product feeds supply the content that is presented on many kinds of e commerce websites such as search engines , Price comparison service price comparison websites , affiliate networks , and other similar aggregators of e commerce information. In some cases they are generated by the online retailer and in some cases the information is extracted using web scraping or harvested web harvesting from the online shops website. Product Feed Applications Product feeds are an integral part of online live scores , sales and marketing, particularly in the case of online retailers with many different products or with products that are described by many different attributes, or in industries in which pricing and availability frequently change. Product feeds are used within a variety of online marketing channels that help shoppers locate the product they wish to purchase and drive the traffic to the retailers website. These marketing channels include Price comparison service Price comparison websites Feeds are the product descriptive content needed to run sites that compare pricing price comparison websites , attributes mostly in vertical search portals and availability.

In telecommunications and electronics , an antenna feed refers to the components of an Antenna radio antenna which feed the radio wave s to the rest of the antenna structure, or in receiving antennas collect the incoming radio waves, convert them to electric currents and transmit them to the receiver. Antennas typically consist of a feed and additional reflecting or directive structures such as a parabolic dish or parasitic element s whose function is to form the radio waves from the feed into a beam or other desired radiation pattern . In simple antennas the feed usually consists of the feed antenna driven element , the part of the antenna which actually converts the radio frequency currents to radio waves or vice versa, and the feed line transmission line , which connects the feed antenna with the receiver or transmitter. For example, in a rooftop Yagi Uda antenna Yagi television antenna the feed consists of a dipole antenna dipole driven element, which converts the radio waves to an electric current, and a coaxial cable or twin lead transmission line which conducts the received signal from the antenna into the house to the television receiver . However in more complex antenna systems the feed can be more complicated. The antenna feed is usually considered to be all the components between the beam shaping part of the antenna and the receiver s first amplifier , called the RF front end , the Low noise block converter LNB or Low noise amplifier LNA . For a transmitting antenna, the feed consists of everything after the last High Power Amplifier power amplifier , and might include an antenna tuner unit and impedance matching sections at the antenna.
