    摘要： The present invention relates to a novel process for refining the liquefied petroleum gas (LPG) in a commercial scale. The process comprises: sequentially performing fine desulfurization and mercaptan conversion of the LPG after alcohol amine treatment through desulfurizer and catalyst set in fixed bed reactor in the absence of alkali, wherein, during the fine desulfurization, the resultants of reaction between hydrogen sulfide in the LPG and Fe—Ca oxides or their hydrates adhered on the desulfurizer, and during the mercaptan conversion, the mercaptan in the LPG reacts with the residual trace amount of air in the LPG under the action of the catalyst to produce the disulfides; letting the formed disulfides along with the LPG flow out of the fixed bed reactor; rectifying the LPG after the mercaptan conversion to obtain the refined LPG products, with further rectification to obtain the valuable disulfide products. The present process has advantages of high efficiency, no alkali discharge, being a simplified process over the prior method using alkali treatment and making no environmental pollution.

    摘要： A method for context-aware text recognition employing two neuromorphic computing models, auto-associative neural network and cogent confabulation. The neural network model performs the character recognition from input image and produces one or more candidates for each character in the text image input. The confabulation models perform the context-aware text extraction and completion, based on the character recognition outputs and the word and sentence knowledge bases.

    摘要： An apparatus for a hybrid architecture that consists of a general purpose microprocessor and a hardware accelerator for accelerating the discovery of DNA reverse complement, edit distance codes. Two embodiments are implemented and evaluated, including a code generator that uses a genetic algorithm (GA) to produce nearly locally optimal codes in a few minutes, and a code extender that uses exhaustive search to produce locally optimum codes in about 1.5 hours for the case of length 16 codes. Experimental results demonstrate that the GA embodiment can find ˜99% of the words in locally optimum libraries, and that the hybrid architecture embodiment provides more than 1000 times speed-up compared to a software only implementation.

    摘要： Methods and apparatus are described for facilitating physical synthesis of an integrated circuit design. A set of paths between observable nodes in a netlist representing the circuit design is generated. Each path corresponds to a sequence of signal transitions. Transistors represented in the netlist are sized to attempt to meet a delay constraint for each path. The delay constraint corresponds to a unit delay times the number of signal transitions in the corresponding path. A plurality of individual delays of different durations are allocated among the transitions for at least one of the paths to meet the delay constraint. At least one of the individual delays exceeds the unit delay.
