  • Publication number: 20250137925
    Abstract: The present disclosure provides a detection and analysis method for rapid delineation of aging stages of styrene-butadiene-styrene (SBS) modified asphalt, including the following steps: performing a Fourier transform infrared spectroscopy (FTIR) test on unaged SBS-modified asphalt samples to obtain a copolymer index of IB0/S0 and neat asphalt functional group indexes, including the SI0, IB, aI0, ARI0, and CI0; performing the FTIR test on the aged SBS-modified asphalt samples to obtain an actual index of IB/S, SI, IB, aI, ARI, and CI; and delineating three aging stages of SBS-modified asphalt, including a polymer swelling stage, a polymer degradation stage and a component imbalance stage according to changes of functional group indexes. According to the present disclosure, the actual aging stages of the SBS-modified asphalt can be determined rapidly and accurately, providing a reasonable basis for the decision on pavement maintenance timing and mode.

  • Publication number: 20230316509
    Abstract: The present disclosure provides an intracranial artery stenosis detection method and system. The present disclosure obtains artery stenosis detection results based on a first maximum intensity projection (MIP) image and a second MIP image obtained by preprocessing a medical image by adopting a detection model based on an adaptive triplet attention module and generates an auxiliary report and visualization results according to target category information in the artery stenosis detection results. Therefore, the problem that existing manual interpretation methods are easily affected by the subjective experience of doctors and are time-consuming and laborious can be solved, thus improving accuracy and efficiency of intracranial artery stenosis detection.

  • Patent number: 10122783
    Abstract: In order to ingest data from an arbitrary source in a set of sources, a computer system accesses predefined configuration instructions. Then, the computer system generates a dynamic data-ingestion pipeline that is compatible with a Hadoop file system based on the predefined configuration instructions. This dynamic data-ingestion pipeline includes a modular arrangement of operators from a set of operators that includes: an extraction operator for extracting the data of interest from the source, a converter operator for transforming the data, and a quality-checker operator for checking the transformed data. Moreover, the computer system receives the data from the source. Next, the computer system processes the data using the dynamic data-ingestion pipeline as the data is received without storing the data in memory for the purpose of subsequent ingestion processing.

  • Patent number: 9991998
    Abstract: The present invention discloses a method, an apparatus and a computer program for resource contention in device-to-device communication links. The method partitions the time-frequency radio resource grid with a resource block set forming the resource unit in the grid, for all available, used and unusable frequency bands around a given virtual central frequency. Each resource block set is partitioned into a common control channel and a data channel. With a given procedure of control data transmission between transmitting and receiving user terminals, the resources are competed and shared. Frequency shifting with short distance frequency change or frequency transference with a larger frequency hopping into a free radio resource is available. The competition procedure is done in order to fairly share the frequency bands as a function of time between different device-to-device communication links in a localized manner.

  • Patent number: 9015169
    Abstract: A method for tenant placement in a multi-tenant system is shown that includes creating a weighted graph of tenants and sharing relationships between tenants, where a weight for each tenant and each sharing relationship represents an associated degree of resource consumption; and adding one or more tenants to a database using a processor based on said weighted graph and a database capacity, such that the combined weight of the added tenants and the sharing relationships belonging to the added tenants are within the database capacity. If a tenant cannot be added to the database without exceeding the database capacity, a new database is created and the one or more tenants are added to the new database, subject to a new database capacity. The adding and creating steps are repeated until all tenants have been added to a database.

  • Patent number: 8874587
    Abstract: Methods for generating a data fetching plan in a multi-tenant system include placing tenants in consecutively allocated databases according to a weighted graph of tenants and sharing relationships between tenants, where at least one sharing relationship includes multiple accessing tenants accessing a given set of data from a provider tenant. For each sharing relationship, if a current database has one or more accessing tenants and does not have the provider tenant, data is fetched from the latest-allocated database prior to the current database that has accessing tenants, if such a database exists; if a current database has the provider tenant, data is provided to the earliest-allocated database after the current database that has accessing tenants if such a database exists. The fetching and providing steps are repeated for each allocated database.
