Abstract: The present application proposes a method and system for quantitative derivation of an on-line evaluation layered model for evaluating concrete dam operation performance, and a storage medium, and relates to the technical field of dam operation safety monitoring and management. A logic architecture of quantitative derivation of the concrete dam operation performance mainly has two aspects, a longitudinal dimension and a transverse dimension. The longitudinal dimension is the principal line of assessing longitudinal evaluation of the on-line evaluation layered model, and an analysis idea of the concrete dam from local to global and from details to whole is objectively reflected from six levels of monitoring data, diagnosis methods, monitored items, evaluation indicators, key parts and an overall project.

Abstract: A method for preventing an error from being triggered includes receiving a sanitizer report of a program as an input, analyzing the sanitizer report to find information about an error in a sanitized kernel image, mapping the information about the error to a native kernel image, constructing a triggering condition based on the information in a native kernel image, and in a case where the triggering condition is met, sending a command to an operating system to kill the program in the native kernel image.

Abstract: A firewall processing card from a plurality of firewall processing cards coupled to a chassis, is selected by a load balancing engine (or other mechanism) and receives the data packet over the fabric channel. First, if the session match exists to management-type data packets the data packet is returned to the I/O board and if a match exists to user data packets the data packet is sent to a firewall service of the firewall processing card. If no session match exists, the firewall processing card checks for a policy match to the data packet for creating a new session or drops the data packet. The I/O board receives the data packet returned from the processing blade over the base channel and checks for a session matching to the data packet. If a session match exists and the data packet is a management data packet, the data packet is sent to a management service at a user level of the I/O board and if not a management data packet the data packet is dropped.

Abstract: The present disclosure discloses a latitude-free construction method for a gravity acceleration vector under a swaying base earth system. Firstly, a target function based on output information of an accelerator in a fixed-length sliding window under a swaying base is constructed; secondly, measurement information in a period of time window is used to construct the target function, and gradient descent optimization is used to obtain a rough value of qiib0; and finally, the rough value of qiib0 and an apparent motion of a gravity acceleration vector of an inertial system are used to construct the gravity acceleration vector under the earth coordinate system. The present disclosure makes a key breakthrough for solving the problem of high precision alignment of a ship with unknown latitude under a swaying base.

Abstract: The present disclosure designs a rotation matrix-based factor graph cooperative localization algorithm. Firstly, the reasons of sudden increase in an error in an operation process of a conventional factor graph cooperative localization algorithm are analyzed; secondly, a rotation matrix is designed, and the size of a rotation angle is determined; then, a rotation matrix-based cooperative localization algorithm factor graph model is constructed, and a specific algorithm flow is designed; and finally, filtering fusion estimation is performed on position status information of a slave boat.

Abstract: Multiple input items from extensions of listened-to sites are received and stored in a common format for a given user. Compound conditions that are linked to the commonly formatted data can be analyzed and one or more mapped requests can be constructed from mappings. The mapped requests can then be transmitted to external sites for processing.
