In the method, a property of at least one of a first segment and a second segment in a segment set is obtained. The segment set includes a plurality of segments belonging to at least one conversation. The second segment occurs after the first segment.

Abstract: The present invention discloses a method for controlling transmission security of an industrial communication flow based on an SDN architecture. The method comprises: designing a flow security control module in a management controller, performing in-depth parsing on industrial communication flow data, matching the parsing result with each preset industrial rule policy, and executing a control processing operation of the industrial rule policy, to implement transmission control of an industrial communication flow. The management controller comprises an industrial rule policy database used for storing all industrial rule policies set by a user. An SDN switch maintains a structure of a flow table, and an industrial communication flow is forwarded according to the flow table. The flow table comprises a security control identifier used for indicating whether security transmission of this communication flow needs to be controlled.

Abstract: The present application discloses a method for automatically establishing an intrusion detection model based on an industrial control network, including: judging whether a first intrusion detection model meets preset detection requirements, and extracting communication behavior traffic data in real time if not; setting a training data set and a test date set according to the communication behavior traffic data; establishing an initial intrusion detection model according to the training data set; and testing the initial intrusion detection model using the test date set, and establishing a second intrusion detection model meeting the preset detection requirements according to the test result. The second intrusion detection model has high detection accuracy, thereby increasing intrusion detection rate of abnormal behavior and reducing false positive rate and false negative rate.

Abstract: A distributed tempero-spatial query service uses a plurality of service agents each having an assigned area of responsibility. The service agents are organized into a spatial hierarchy based upon each service agent's area of responsibility. The spatial hierarchy is distributed and hosted on each of the service agents. The spatial hierarchy enables matching of requests from subscribing agents with publishing agents based upon spatial attributes. The spatial hierarchy is dynamically maintained in a distributed manner on each of the service agents. The service agents can be arranged into a tree-based spatial hierarchy having a limited depth.

Abstract: In accordance with the present invention, a method for determining a centerline through a region of interest in a 3D image dataset is provided. The method includes identifying the boundaries of the region of interest and identifying the endpoints of the region of interest. For those points within the boundaries, a penalty value which is a function of the proximity of the point to a boundary is determined. A centerline is then identified by the path connecting the endpoints which has the minimum penalized distance wherein the penalized distance reflects the actual accumulated pathlength and the penalties associated with the points along the path. From the centerline, branches of a complete skeleton can be established by determining branch endpoints and then finding the minimum penalized distance from each endpoint the centerline or another intersecting branch.

Abstract: Methods for generating a centerline or skeleton structure within a 3D virtual object are provided. A first method defines a centerline based on distance from boundary values along points of the defined centerline. A second method uses a distance from boundary field to assign costs to voxels in the virtual object and defines a minimum cost spanning tree based on assigned costs. The centerline is defined along the minimum cost spanning tree. Branches along the centerline are identified and added to the centerline to define a skeleton.
