Abstract: A defect detection system includes one or more route optical sensors configured to generate image data depicting an underbody of a vehicle that is on a route. The defect detection system also includes a controller configured to input the image data generated by the one or more route optical sensors into a first machine learning algorithm that determines an area of interest in the image data. The area of interest contains equipment of interest. The controller is configured to input the image data that is within the area of interest into a second machine learning algorithm that detects a defect on the equipment of interest. The controller is configured to perform at least one responsive action based on a type of defect that is detected.

Abstract: A fuel control system obtains a measured amount of fuel consumed by an engine and one or more corresponding operating parameters of the engine and determines a fuel consumption modeled amount based at least in part on a fuel consumption model of the engine and the one or more operating parameters. The fuel consumption model associates different amounts of fuel that, when supplied to the engine, generate corresponding designated outputs of the engine. The system also determines one or more differentials between the measured amount of fuel and the modeled amount and, responsive to the one or more of the differentials exceeding a threshold value, the system identifies one or more components of the powered system that contribute or cause the one or more differentials and/or changes an amount of fuel supplied to the engine according to the fuel consumption model to obtain a desired output of the engine.

Abstract: A method of processing medical image data includes receiving data indicative of a group of consecutive cross sectional images of a three dimensional volume being imaged. The group of consecutive cross sectional images has a first axial resolution in a z-axis direction and a first spatial resolution in x-axis and y-axis directions orthogonal to the z-axis. The method also includes transforming, such as by wavelet transforming, the group of consecutive cross sectional images in the z-axis direction to generate an axially transformed representation of the group, so that the axially transformed representation has a second axial resolution lower than the first axial resolution. The method may also include transforming the axially transformed representation in x-axis and y-axis directions to generate a spatially transformed representation.
