摘要： A probabilistic system for tracking a state of a vehicle using unsynchronized cooperation of information includes a probabilistic multi-head measurement model relating incoming measurements with the state of the vehicle. The first head of the model relates measurements of the satellite signals subject to measurement noise with a belief on the state of the vehicle, and a second head relates an estimation of the state of the vehicle subject to estimation noise with the belief on the state of the vehicle. A probabilistic filter of the system updates recursively the belief on the state of the vehicle based on the multi-head measurement model accepting one or a combination of the measurements of the satellite signals subject to the measurement noise and the estimation of the state of the vehicle subject to the estimation noise.

摘要： A server jointly tracks states of multiple vehicles using measurements of satellite signals received at each vehicle and parameters of the probabilistic distribution of the state of each vehicle. The server fuse states and measurements into an augmented state of the multiple vehicles and an augmented measurement of the augmented state subject to augmented measurement noise defined by a non-diagonal covariance matrix with non-zero off-diagonal elements, each non-zero off-diagonal elements relating errors in the measurements of a pair of corresponding vehicles. The server executes a probabilistic filter updating the augmented state and fuses the state of at least some of the multiple vehicles with a corresponding portion of the updated augmented state.

摘要： A controller for controlling a vapor compression system is provided. The controller is configured to control an operation of the VCS with different combinations of setpoints for different actuators of the VCS to estimate a cost of operation of the VCS for each of the different combinations of setpoints, and compute, using a Bayesian optimization of the combinations of setpoints and their corresponding estimated costs of operation, a probabilistic surrogate model, wherein the probabilistic surrogate model defines at least first two order moments of the cost of operation in the probabilistic mapping. The controller is further configured to select an optimal combination of setpoints having the largest likelihood of being a global minimum at the surrogate model according to an acquisition function of the first two order moments of the cost of operation.

摘要： An image processing method for measuring displacement of an object is provided. The method includes acquiring first sequential images and second sequential images, wherein two adjacent images of the first sequential images include first overlap portions, wherein two adjacent images of the second sequential images include second overlap portions, wherein the first sequential images correspond to a first three dimensional (3D) surface on the object at a first state and the second sequential images correspond to a second 3D surface on the object at a second state. The method further includes deblurring the first sequential and second sequential images to obtain sharp focal plane images based on a blind deconvolution method, stitching the sharpened first sequential images and the sharpened second sequential images into a first sharp 3D image and a second sharp 3D image based on camera pose estimations by solving a perspective-n-point (PnP) problem using a refined robust weighted Levenberg Marquardt (RRWLM) algorithm, respectively. The method further comprises forming a first two-dimensional (2D) image and a second 2D image by unfolding, respectively, the first sharp 3D image and the second sharp 3D, and generating a displacement(strain) map image from the first 2D and second 2D images by performing a two-dimensional digital image correction (DIC) method.

摘要： A system for controlling an operation of an induction motor (IM). A controller processor detects a spectrum of a current signal from received sensor data using a module. Obtain a number of rotor bars and a number of pole pairs of the IM to identify a principle slot harmonics (PSH) type IM from stored IM data. Use the PSH-type IM to identify a static eccentricity (SE) fault signature signal located at a secondary PSH frequency of the PSH-type IM. Determine a level of signal strength in the spectrum of the current signal at a location of the secondary PSH frequency, and compare to a SE fault table database to obtain a SE fault level of the PSH-type IM. Compare the SE fault level to a database to obtain a SE fault threshold, and if the SE fault level is outside the SE threshold, generate an interrupt command to the controller.
