Abstract:
A non transitory computer readable medium and a method of detecting excavation of an underground tunnel, the method includes: propagating a light pulse through an underground optic fiber; generating detection signals responsive to Brillion scattered light resulting from the propagating of the light pulse through the underground optic fiber; wherein the detection signals represent tension values at multiple locations along the underground optic fiber; and processing the detection signals to detect excavation of the underground tunnel.

Abstract:
A method of estimating heat stress of livestock animals. The method comprises capturing a sequence of images each depicting a thorax of a livestock animal during a monitoring period, analyzing the sequence of images to detect a movement frequency of the thorax during the monitoring period, computing a breathing rate of the livestock animal as a function of the movement frequency, and estimating a heat stress status for the livestock animal according to the breathing rate.
Abstract:
A system for stabilizing a single-track vehicle including a front assembly and a rear assembly, said system comprising a robust controller including an inner loop which closes on a roll angular rate {dot over (χ)} of said rear assembly and reduces parametric uncertainty associated with said vehicle, and an outer loop which closes on a roll angle χ of said rear assembly, and wherein the robust controller outputs a steering torque signal for controlling a steering angle in said front assembly; a roll angle sensor for measuring the roll angle in the rear assembly; a roll rate gyro for measuring the roll angular rate in the rear assembly; and a motor for applying the steering angle to said front assembly responsive to the steering torque signal.
