  • Publication number: 20250094316
    Abstract: For a set in sets of candidate factors, a classification model is trained to predict a computer problem possibility, an accuracy score of the classification model is determined based on model validation, and factor weights of the candidate factors in the set are adjusted based on the accuracy score. This processing is done with respect to all sets of candidate factors. A low accuracy classification model having an accuracy score lower than a threshold criterion is selected. A higher accuracy classification model having an accuracy score that is higher than the accuracy score of the low accuracy classification model is selected. The set of candidate factors used to train the low accuracy classification model is updated using one or more of the candidate factors used to train the higher accuracy classification model. The low accuracy classification model is updated based on the updated set of candidate factors.

    Abstract: A computer-implemented method, system and computer program product for improving accuracy and efficiency of auditing databases. A table, list or index of a database is analyzed to identify metadata, which includes time series data, user data, an Internet Protocol address and operation data. The identified metadata is associated with the corresponding record or row of the table, list or index from which the metadata was extracted. A determination is then made as to whether to record a raw data image associated with the record or row of the analyzed table, list or index based on the corresponding data operation. The identified metadata as well as the recorded data images, if any, are stored in a structured audit log. Auditing information is then obtained from a structured audit log based on matching the record or row identifier (RID) associated with the query with the RID associated with the structured audit log.

  • Patent number: 12247359
    Abstract: A road network balanced drainage method aimed at reducing urban waterlogging is disclosed. According to the drainage demand, the existing intersection elevation is changed or the intersection elevation that meets the drainage requirement is designed and implemented in new construction so that the intersection drainage is distributed according to the desired proportion; the water flowing to the water accumulation position is transferred to reduce the waterlogging degree. Through the analysis of the depth of water accumulation in the whole road network, the method of water flow distribution at the intersection is used to make the precipitation flow evenly distributed in the whole road network. The method can be used for solving serious water accumulation of a certain road section, the balanced drainage of the whole road network, the technical transformation of existing intersections, and for the planned and designed roads. The method can effectively eliminate and prevent urban waterlogging.

  • Publication number: 20250081593
    Abstract: Methods of manufacturing electronic devices, such as transistors (negative metal-oxide-semiconductor (NMOS) transistors (e.g., an N-metal stack) and positive metal-oxide-semiconductor (PMOS) transistors (e.g., a P-metal stack)) are described. Embodiments of the disclosure are directed to methods of improving PMOS transistor performance by inhibiting N-metal layer growth. The present disclosure provides two types of processes to reduce or inhibit N-metal layer growth. The disclosure provides methods which include forming a self-assembled monolayer (SAM) on the metal surface (e.g., titanium nitride (TiN)) of the PMOS, and methods which include forming a silicon-containing layer such as silicon oxide (SiOx) on the TiN surface. These two types of processes significantly reduce or inhibit the subsequent growth of an N-metal layer, such as titanium aluminum carbide (TiAlC), on the TiN surface of the PMOS.
