Abstract: Systems and processes for identifying a pointer in an image of an analog instrument are provided herein. An instrument contour in the image corresponding to the analog instrument may be identified. A plurality of candidate pointer contours in the image may be identified and screened using one or more geometric property screening techniques including an evaluation of a geometric area, a distance parameter, and/or a gravity center of the plurality of candidate pointer contours. Principal component analysis (PCA) may be performed to select an identified pointer contour from among the reduced plurality of candidate pointer contours. A linear regression model may be applied to pixel points in the contour area of the identified pointer contour and a slope and angle of an associated pointer represented by the identified pointer contour may be determined based on an output of the linear regression model.

Abstract: Various embodiments for a transport dispatch system for route selection are described herein. An embodiment operates by determining the total quantity of goods to be shipped to the plurality of railway stations. A plurality of variations of the shipping route are identified. A user-provided metric is computing for each of the plurality of variations of the shipping route. A first variation is identified from the plurality of variations of the shipping route for which the computed user-provided metric is lower than a remainder of the plurality of variations of the shipping route, The first variation of the shipping route is provided indicating an order in which each of the plurality of stations receives its portion of the total quantity of goods based on its request.

Abstract: A computer-implemented method for failure diagnosis using fault tree can include: receiving a fault tree comprising a node representing a top event, a plurality of nodes representing respective basic events, and one or more logic gates connecting the plurality of nodes representing the respective basic events to the node representing the top event; obtaining reliability parameters corresponding to the basic events; calculating fault tree importance measures corresponding to the basic events; calculating failure impact factors of the top event corresponding to the basic events, wherein the failure impact factors of the top event are products of the corresponding reliability parameters and the corresponding fault tree importance measures; ranking the basic events based on the failure impact factors of the top event; and identifying a most significant contributor to the top event, wherein the most significant contributor is a basic event having the highest failure cause probability of the top event.
