We present 3 methods for the subtraction of non-cosmic and unresolved cosmic backgrounds observed by the Low-Energy Concentrator Spectrometer (LECS) on-board BeppoSAX. Removal of these backgrounds allows a more accurate modeling of the spectral data from point and small-scale extended sources. At high (> | 25 | (deg) ) galactic latitudes, subtraction using a standard background spectrum …

01.03.2016· Among the solar concentrators, parabolic dishes have the highest efficiency in the conversion of solar energy to electricity with an efficiency of 29.4% achieved . Such systems have high optical efficiencies and low start-up losses leading to highly efficient solar energy engines. This gives the parabolic dishes the potential to eventually become one of the least expensive forms of renewable ...

01.01.2006· To develop low-pollution burners, the effect of a coal concentrator on NO formation in swirling coal combustion is studied using both numerical simulation and experiments. The isothermal gas–particle two-phase velocities and particle concentration in a cold model of swirl burners with and without coal concentrators were measured using the phase Doppler particle anemometer (PDPA). A …

Concentrator optics concentrate incident radiation onto thermal or photovoltaic receivers. We investigate and develop single stage and multistage concentrator designs based on reflective (e.g. parabolic mirrors, heliostats) or refractive optics (e.g. Fresnel lenses or dielectric secondary concentrators) for linear or spot focusing systems in low, medium and high concentration applications.

An oxygen concentrator is a device that concentrates the oxygen from a gas supply (typically ambient air) by selectively removing nitrogen to supply an oxygen-enriched product gas stream. Two methods in common use are pressure swing adsorption and membrane gas separation. History. Home medical oxygen concentrators were invented in the early 1970s, with the manufacturing output of these …
