The use of remotely sensed near-surface soil moisture for the estimation of evaporation is investigated. Two widely used parameterizations of evaporation, the so-called alpha and beta methods, which use near-surface soil moisture to reduce some measure of ...
Alfven eigenmodes and other magnetohydrodynamic phenomena have been studied in tokamak plasmas at the Joint European Torus (JET) using a new eight-channel, 4 s, 1 MHz, 12-bit data acquisition system (KC1F) in conjunction with the JET fast Mirnov magnetic f ...
This paper present a polarimetric fiber optics current sensor using a 22.5 degree Faraday rotator and a Faraday rotation mirror. The objective of this sensor is to be low-cost, high accuracy and easy to manufacture ...

Highly accurate group delay measurements in long single-mode fibers were achieved over the full 1200-1600 nm spectral range by measuring phase shifts of a modulated lightwave. The high modulation frequency is shifted down to the kilohertz range using a sec ...
A new method of camera calibration is proposed for active visual sensing for use in 3D analysis. The method, based on a variation of the two plane camera model, permits the calibration of a mobile camera as a function of the position and orientation of the ...
A new method of calibration is proposed for active visual sensing for use in 3D analysis. The method, based on an adaptation of the two-camera plane model, permits the calibration of a mobile camera as a function of the position and orientation of the came ...
Different remote sensing techniques have been used for the analysis of the air pollution in the Milan area. Results and intercomparisons from two lidars are presented, obtained from a ground based and an airborne instrument. Combining them with range resol ...
A novel piezoelectric thin-film accelerometer has been designed and its performance has been analysed. The piezoelectric thin film (PZT for example) is delineated into an array of pads to reduce the sensor capacitance. By filling the cavity around the PZT ...
