SUMMARY The GRACE Atmosphere and Ocean Level-1B (AOD1B) product is routinely applied in the processing of satellite gravimetry data to mitigate impact temporal aliasing. Spurious trends, low-frequency signals or bias jumps background model can, if unaccounted for, introduce biases into global gravity solutions which might be interpreted erroneously subsequent geophysical analyses. Here, we exam...

This paper presents passive radar emitter localization using the Time-Difference-Of-Arrival (TDOA) technique from Unmanned Aerial Vehicles (UAVs) working in conjunction with a fixed/mobile station (such as a shipborne/land-based station) to geolocate a radar emitter to fulfill maritime and littoral area surveillance. Instead of using multiple stationary sensors, multiple TDOA measurements are o...

Isothermal titration calorimetry has been applied in combination with a moisture generator and, independently, gravimetry to study the adsorption of water onto 50 mg of the lipid dioleoylphosphatidylcholine. During the experiment, the relative humidity is varied stepwise, e.g. from 2% to 92% in increments of 2% every 15 min. The difference between the partial molar enthalpy of the water molecul...

In this study we evaluate the laser cleaning of tarnished pure and sterling silver substrates using a nanosecond Q-switched Nd:YAG laser at 1064, 532 and 266 nm. To assess the effects associated with cyclic laser cleaning treatments, several cycles of tarnishing followed by laser cleaning were applied on silver coupons that were characterized by gravimetry, colorimetry, scanning electron micros...

We derive a stable technique, based upon matrix pencils, for the reconstruction of (or approximation by) polygonal shapes from moments. We point out that this problem can be considered the dual of 2 D numerical quadrature over polygonal domains. An analysis of the sensitivity of the problem is presented along with some numerical examples illustrating the relevant points. Finally, an application...
