A display includes a polarizing member and a reflective display element behind an EL element. The EL element self-emits light to display information and doubles as a display-use light source for the reflective display element. In a sufficiently bright environment, ambient light enters a liquid crystal layer after passing through a frontal substrate of the reflective display element, and is reflected from a metal electrode to produce displays. In addition to the direct light from the EL element, light that enters the liquid crystal layer is simultaneously used. In a dark environment, the EL element emits light, and displayed contents are visible owing to the reflection from the metal electrode as well as directly exiting light. The structure makes it possible to provide a novel type of display that allows a user to select one of various display modes at his / her own discretion according to surrounding conditions and that also shows information in a clearly visible fashion, be it outdoors under clear skies or in a dark place, without giving up their thin, lightweight features.

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 method of biologically treating wastewater with an integrated fixed film activated sludge process. The integrated fixed film activated sludge process includes biomass suspended in mixed liquor and biomass disposed on carriers. Under certain conditions the dissolved oxygen concentration in a reactor that includes the mixed liquor, biomass suspended in the mixed liquor, and the biomass on the carriers, biological treatment is performed primarily by the biomass in the mixed liquor. This is achieved by controlling or maintaining the dissolved oxygen concentration in the reactor at a relatively low concentration. When the biomass suspended in the mixed liquor is unable to adequately biologically treat the mixed liquor, the dissolved oxygen concentration in the reactor is controlled or maintained at a relatively high concentration. This enables biomass on the carriers to contribute more to the biological treatment of the mixed liquor than when the dissolved oxygen concentration was maintained relatively low.

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.

As a result, a larger process window is realized and lower asymmetry output during a read operation is achieved.

Shockwave-only solutions that estimate shooter position and shot trajectory are extremely sensitive to the quality and precision of the shock time-of-arrival (TOA) measurements as well as the accuracy to which relative sensor positions in space are known. Over the life of a long-deployed system, the sensor positions can shift and the performance of some sensors may degrade for various reasons. Such changes can degrade the performance of deployed shooter estimation systems. Disclosed are systems and methods that can be used to calibrate sensor positions based on shock and muzzle measurements processed from a series of shots fired from a known location and in a known direction, as well as an approach for dynamically adapting shock-only shooter estimation algorithms to compensate for sensor degradation and / or loss.

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.
