    摘要： A deinterleaver device, a method for deinterleaving, an interleaver device, and a method for interleaving are provided. The method for deinterleaving includes: providing a memory and a stream count for a frame; virtually dividing the memory into equal sections, wherein a section count equals the stream count; calculating a write address for a sample of the samples based on a location of the sample in the frame and a correspondence of the location to one of the sections; receiving the sample; and writing the received sample to the write address, wherein the calculating and the write address corresponds to a correct deinterleaving location in one of the sections for the sample.

    摘要： A system and method for filtering code blocks to maintain high throughput thru a Forward Error Correcting (FEC) decoder is disclosed. The method includes: monitoring a Signal-to-Noise Ratio (SNR) for an incoming link; selecting a rank table including a rank, Modulation and Coding Rate (MODCOD), and a minimum SNR; determining a threshold MODCOD range from the rank table based on the SNR; demodulating an incoming frame; identifying, in the incoming frame, the code blocks and an associated MODCOD for each of the code blocks; selecting a code block from the code blocks when the respective MODCOD for the code block is in the rank table and within the threshold MODCOD range; and decoding the selected code block with the associated MODCOD.

    摘要： A process is provided for carrying out an oxidation on a feed including levulinic acid and/or a levulinic acid oxidation precursor to succinic acid, one or more furanic oxidation precursors of 2,5-furandicarboxylic acid and a catalytically effective combination of cobalt, manganese, and bromide components for catalyzing the oxidation of the levulinic acid component and of the one or more furanic oxidation precursors to produce both succinic acid and 2,5-furandicarboxylic acid products, which process comprises supplying the feed to a reactor vessel, supplying an oxidant, reacting the levulinic acid component and the one or more furanic oxidation precursors with the oxidant to produce both succinic acid and 2,5-furandicarboxylic acid (FDCA) and then recovering the succinic acid and FDCA products. A crude dehydration product from the dehydration of fructose, glucose or both, including 5-hydroxymethylfurfural, can be directly oxidized by the process to produce 2,5-furandicarboxylic acid and succinic acid.

    摘要： Commercially feasible methods for lyophobic precipitation of liquid-dispersed or dissolved material (e.g., medicaments) are provided wherein a plurality of individual, open containers (22) each containing a quantity (84) of a solution or dispersion are treated within a common pressurizable chamber (12). In this process, desired near-supercritical or supercritical temperature and pressure conditions are established for a selected antisolvent gas such as carbon dioxide, and an ultrasonic device (14) is actuated to generate high energy ultrasonic waves in the chamber (12). This leads to intense mixing of the antisolvent with the liquid solution or dispersion within the containers (22), with consequent solvent removal and material precipitation.
