    摘要: The invention relates to a quality of service (QoS)-aware parallel flexible Skyline service discovery method, including: performing, by each parallel node, a tournament selection algorithm to trim candidate services inside the parallel node; then making each parallel node perform a block dominance algorithm to filter candidate services inside the parallel node to obtain local Skyline services; collecting all local Skyline services to form a first set, and then performing filtering on the first set by using the block dominance algorithm to obtain global Skyline services; and determining whether there is a first constraint in the global Skyline services, and if yes, performing processing by using a flexible Skyline service correction algorithm to obtain a flexible Skyline service set for output, or otherwise, directly outputting the global Skyline services. The present invention reduces calculation complexity, and improves the accuracy of service selection, thereby facilitating accurate, efficient filtering to obtain quality services.

    摘要: The invention provides a Siniperca chuatsi IL-6 gene and a detection method for a disease-resistant SNP marker. A cDNA sequence of S. chuatsi IL-6 gene is cloned, as shown in SEQ ID NO: 1. A IL-6 gene gDNA sequence containing an intron of the S. chuatsi IL-6 gene is cloned, as shown in SEQ ID NO: 2. A primer for amplifying a disease-resistant SNP locus is designed according to IL-6 gDNA sequence, and S. chuatsi IL-6 gene is amplified to obtain an amplification product which is sequenced, and the SNPs loci relevant to virus disease-resistance are found out and the SNP locus is determined according to DNA peak profile. The IL-6 cDNA full-length sequence and IL-6 gDNA full-length sequence are cloned firstly. The SNP locus relevant to virus disease resistance of S. chuatsi IL-6 gene is detected, thereby providing a new method for breeding of S. chuatsi.

    摘要: An asset allocation method integrates the behavioral finance theory, optimization algorithm, and a 3 step algorithm. The method selects a plurality of assets upon a financial index by a computer system to create an asset group, then allocates the weight of the asset group to minimalize its standard deviation of expected profit and its skewness, and select another plurality of assets to refresh the asset group when its stability index exceeds a threshold value or has not refreshed for a stagnant duration. Thus, the asset allocation method would enable to provide the investor with a financial derivative and allocation model that met the investor's risk performance and earned a profit more than the benchmark.

    摘要: Provided is a contour shape recognition method, including: sampling and extracting salient feature points of a contour of a shape sample; calculating a feature function of the shape sample at a semi-global scale by using three types of shape descriptors; dividing the scale with a single pixel as a spacing to acquire a shape feature function in a full-scale space; storing feature function values at various scales into a matrix to acquire three types of feature grayscale map representations of the shape sample in the full-scale space; synthesizing the three types of grayscale map representations of the shape sample, as three channels of RGB, into a color feature representation image; constructing a two-stream convolutional neural network by taking the shape sample and the feature representation image as inputs at the same time; and training the two-stream convolutional neural network, and inputting a test sample into a trained network model to achieve shape classification.
