Pursuit-evasion differential games using the Disturbance Attenuation approach are revisited. Under this approach, pursuer actions considered to be control actions, whereas all external such as target maneuvers, measurement errors and initial position uncertainties, disturbances. Two open issues have been addressed, namely effect of noise on gains, trajectory shaping solution. These closely rela...

ultrasonic testing (ut), a nondestructive testing (ndt) method, is under development for quality determination of agricultural products, although it has long been used in the food industry. determination and measurement of product quality are important in modern agricultural research. noninvasive/nondestructive quality determination is a novel aspect of the postharvest process in which paramete...

Rain over the oceans causes attenuation of communication and radar signals for satellites and backscatter to satellite radars. To determine the attenuation and backscatter, one must know the height of the rain in a storm, and must be able to find it from a satellite measurement likely to be available. Microwave radiometers on satellites can provide estimates of rain rates, and therefore relatin...

Fibre optic radiation monitors have promising applications in the nuclear industry. We investigate the possible use of PMMA plastic optical fibres as on-line dosimeters, based on the measurement of the attenuation induced by the ionising gamma radiation. A novel interrogation scheme is proposed for real-time dosimetry applications. This technique involves using spectral measurement techniques w...
