Jet nebulizers show an unreasonable variation in drug output and nebulization rates that leads to clinical and regulatory problems. Current evaluation methods appear inadequate for the purpose. Our objective was to evaluate Technetium-99m radiometry to study nebulizer parameters and the factors influencing it quantitatively. Drug output, output rate and residual mass and the effect of excipient...

This paper present the results of a preliminary study to assess the potential of the visible, NIR and SWIR energy of the EMR in differing iron ores of different grades in a rapid manner using hyperspectral radiometry. Using different iron ore samples from Noamundi mines, Jharkhand, India, certain spectro-radiometric measurements and geochemical analysis were carried out and the results have bee...

Above-water measurements of water-leaving radiance are widely used for water-quality monitoring and ocean-color satellite data validation. Reflected skylight in above-water radiometry needs to be accurately estimated prior to derivation of water-leaving radiance. Up-to-date methods to estimate reflection of diffuse skylight on rough sea surfaces are based on radiative transfer simulations and s...

The L-band radiometry data and in-situ ground and snow measurements performed during the 2016/2017 winter campaign at the Davos-Laret remote sensing field laboratory are presented and discussed. An improved version of the procedure for the computation of L-band brightness temperatures from ELBARA radiometer raw data is introduced. This procedure includes a thorough explanation of the calibratio...

The bachelor’s degree in Physics at Loyola University Chicago requires both an upper-division course in Optics as well as a companion Optics Laboratory course. Recently, the laboratory course has undergone dramatic changes. Traditional weekly laboratories have been replaced with three laboratory modules, where students focus on a single topic over several weeks after which the students submit a...

Highly fragmented landscape, small plots and ownerships, as well as the undulated topography of Crete cause a challenge for land use/cover mapping via the satellite imageries. Both the enhanced spectral and spatial resolution of WorldView-2 satellite sensor is expected to increase the discrimination potential of the classification process. Field spectroradiometric measurements were acquired usi...

We present issues and solutions concerning the calibration and validation of ENVISAT ASAR image products – both their geometry and radiometry are investigated. Concerning geometric calibration, the slant range products (IMS, APS) offer the best available resolution. We tabulate differences between measured (in image products) and predicted (via geodetic position, precise state vectors, and rang...

OBJECTIVES To compare the performance of a portable radiometer with thermal imaging and to assess the potential for radiometry to provide a practical alternative for assessing vascular responsiveness in Raynaud's phenomenon (RP). METHODS Subjects comprised 18 patients with diagnosed RP and 19 non-RP subjects. A thermal imager (Starsight) and a portable radiometer (Cyclops) measured digital te...
