Abstract: A method and system for accelerating the convergence of an iterative computation code of physical parameters of a multi-parameter system, in particular in the field of fluid dynamic computation. The method comprises obtaining first parameter values, of first dimensionality by applying the iterative computation code. The method further comprises applying a data dimensionality reduction on at least a part of the first parameter values of first dimensionality to compute representative second parameters of second dimensionality smaller than the first dimensionality; applying an extrapolation on at least a subset of the second parameters of second dimensionality to predict a set of predicted second parameter values, computing predicted first parameter values from the predicted second parameter values, and using the predicted first parameter values as an input data set for a new iterative computation with the iterative computation code.

Abstract: A device includes a passive antenna configured to capture a signal beam.

Abstract: An ice merchandiser with a remote monitoring system is provided with one or more LiDAR modules positioned near a top surface an icebox such that the fields-of-view of the LiDAR modules are at least partially directed towards a bottom surface of the icebox. The LiDAR modules provide distance data to the inventory stored within the icebox to a controller located outside of the icebox via a cable that includes both power and data lines. The controller processes the distance data to provide an estimate of the current inventory of the ice merchandiser and communicates at least one of inventory data and other sensor data concerning the operation of the ice merchandiser to a remote server via a network.
