  • Architecture and control of reed-solomon list decoding

    Systems and methods are provided for implementing list decoding in a Reed-Solomon (RS) error-correction system. A detector can provide a decision-codeword from a channel and can also provide soft-information for the decision-codeword. The soft-information can be organized into an order of combinations of error events for list decoding. An RS decoder can employ a list decoder that uses a pipelined list decoder architecture. The list decoder can include one or more syndrome modification circuits that can compute syndromes in parallel. A long division circuit can include multiple units that operate to compute multiple quotient polynomial coefficients in parallel. The list decoder can employ iterative decoding and a validity test to generate error indicators. The iterative decoding and validity test can use the lower syndromes.

  • Method of removing toxins from fly ash

    A method for disposing of fly ash. After the fly ash has been processed using the method contained herein, this fly ash can be disposed of more easily because of the reduced toxicity of the final product. Also, this converted fly ash may be recycled and used as a material or aggregate in concrete. The method includes the treatment of dioxins found in fly ash found in waste incinerator flue from waste incineration power plants which includes collecting the fly ash, putting the fly ash into a hermetic device and treating the fly ash through various heating steps and thereafter lowering an environmental temperature in the hermetic heating device, which results in a significant reduction of dioxins in the fly ash.

  • Integrated data plane for heterogeneous network services

    Network services can be dynamically configured on an integrated data path by establishing control paths between data plane entities located on the integrated data path and service entities associated with the network services. In this way, routing for the integrated data path is performed with fewer restrictions than traditional data planes, which are largely limited by the relative locations of pre-configured network nodes in the service network. As a result, the integrated data path may traverse a shorter or more favorable route over the services network, thereby achieving improved service network performance, lower latency periods, less congestion, etc. Further, a service topology on the integrated data path can be dynamically re-configured through the addition, removal, or reordering of data plane entities on the integrated data path.
