Method for estimating an operational parameter of a motor
A method for estimating an operational parameter of a motor is to be implemented by an estimating device. In the method, the estimating device is configured to: receive an acoustic signal attributed to operation of the motor; process the acoustic signal to obtain a plurality of sample points in the frequency domain, each of which has a frequency and a corresponding amplitude; compute an estimated peak frequency using a centroid method based upon the frequencies and the amplitudes; from a plurality of peak frequencies and a plurality of known values of the operational parameter corresponding respectively to the peak frequencies, select a part of the peak frequencies approximate to the estimated peak frequency and a corresponding part of the known values of the operational parameter; and compute an estimated value of the operational parameter based upon the peak frequencies and the known values of the operational parameter..

Low power centroid determination and texture footprint optimization for decoupled sampling based rendering pipelines
The problem of generating high quality images with a rendering pipeline based on decoupled sampling may be addressed by generating non-extrapolated shading locations and by determining improved texture filtering footprints. This may be accomplished by performing shading at the center of a bounding box that bounds mapped shading samples..

Parallelization of synthetic events with genetic surprisal data representing a genetic sequence of an organism
A method, system, and computer program product for parallelization of updating synthetic events with genetic surprisal data comprising dividing the synthetic event into cohort parts and assigning the cohort parts to one of a plurality of computer processing elements. Within each processing element: searching data records of patients for genetic surprisal data; generating a cluster comprising a centroid by populating the cluster based on all of the matches of the data records; calculating a new centroid for each cluster; calculating a euclidean distance in multiple dimensions for each match of data records to the new centroid for each cluster; reassigning each match of data to the new centroid of each cluster based on the shortest calculated euclidean distance to the new centroid for each cluster; and determining at least one cohort part from the clusters and recombining the cohort parts into updated synthetic events based on the metadata..

Incorporating video meta-data in 3d models
A moving object detected and tracked within a field of view environment of a two-dimensional data feed of a calibrated video camera is represented by a three-dimensional model through localizing a centroid of the object and determining an intersection with a ground-plane within the field of view environment. An appropriate three-dimensional mesh-based volumetric model for the object is initialized by using a back-projection of a corresponding two-dimensional image as a function of the centroid and the determined ground-plane intersection.
