A distributed incentive mechanism is provided for peer-to-peer (P2P) streaming networks, such as mesh-pull P2P live streaming networks. Video (or audio) may be encoded into multiple sub-streams such as layered coding and multiple description coding. The system is heterogeneous with peers having different uplink bandwidths. Peers that upload more data (to a peer) receive more substreams (from that peer) and consequently better video quality. Unlike previous approaches in which each peer receives the same video quality no matter how much bandwidth it contributes to the system, differentiated video quality, commensurate with a peer's contribution to other peers, is provided, thereby discouraging free-riders.

A vehicle suspension provides increased auxiliary roll stiffness by utilizing spring assemblies having a thick truncated half-leaf, a thin full-leaf, and a thin truncated half-leaf located opposite the thick truncated half-leaf. The thick truncated half-leaf increases the torsional rigidity of the spring assembly in order to increase the leaf twist sub-component of auxiliary roll stiffness and increases the bending rigidity of half of the spring assembly in order to increase the axle torsion sub-component of auxiliary roll stiffness. The thin full-leaf provides structural integrity, and the thin half-leaf allows tuning of the overall vertical spring rate of the suspension and limits the leaf stresses in the thin full-leaf.

Search engine reliance on link-based ranking algorithms has been shown to delay the visibility of fresh content added to the World Wide Web (Web), relative to established content. Fresh content abstracts are randomly inserted into top ranked search results to achieve more even visibility coverage of the Web and improve overall search quality. Searcher behavior is monitored to infer a rank for the fresh content, and for established content. Rank that is so inferred is termed “ResultRank.” ResultRank is used to compliment link-based ranking schemes to improve web visibility and avoid a bias toward established links. Searcher satisfaction is monitored during this process since the quality of fresh content is unknown. A search engine extended enterprise metric (R metric) is introduced and designed to monitor aggregate searcher satisfaction. ResultRank and the R metric are used to complement existing ranking and pricing algorithms for sponsored results as well.

A hard bias structure for biasing a free layer in a MR element within a read head is comprised of a composite hard bias layer having a Co_78.6Cr_5.2Pt_16.2/Co₆₅Cr₁₅Pt₂₀ configuration. The upper Co₆₅Cr₁₅Pt₂₀ layer has a larger Hc value and a thickness about 2 to 10 times greater than that of the Co_78.6Cr_5.2Pt_16.2 layer. The hard bias structure may also include a BCC underlayer such as FeCoMo which enhances the magnetic moment of the hard bias structure. Optionally, the thickness of the Co_78.6Cr_5.2Pt_16.2 layer is zero and the Co₆₅Cr₁₅Pt₂₀ layer is formed on the BCC underlayer. The present invention also encompasses a laminated hard bias structure. The Mrt value for the hard bias structure may be optimized by adjusting the thicknesses of the BCC underlayer and CoCrPt layers. As a result, a larger process window is realized and lower asymmetry output during a read operation is achieved.

Chlorine dioxide is produced at high conversion rates from aqueous sodium chlorite solution by electrochemical oxidation in an undivided electrochemical cell. The cell utilizes an anode of high surface area through which the aqueous sodium chlorite solution flows into an interelectrode gap between the anode and a cathode. Water or acidified water is fed into the interelectrode gap to function as catholyte and also to dilute the electrolyzed sodium chlorite solution to provide an aqueous solution of chlorine dioxide exiting from the electrochemical cell.

An optical network system having a global controller capable of controlling all the elements of the network. The controller receives performance data from each optical network element and calculates a performance value for each channel transmitting through the system. The controller then isolates the channel with the minimum performance value and tests possible changes in network element parameters to find a change which would increase this performance value. Once such a change is found, it is implemented and the system is reoptimized.
