This paper deals with the reconstruction of the direction of a gravitational wave source using the detection made by a network of interferometric detectors, mainly the LIGO and Virgo detectors. We suppose that an event has been seen in coincidence using a filter applied on the three detector data streams. Using the arrival time (and its associated error) of the gravitational signal in each dete...
To assess the quality of retrieved products from ground-based microwave radiometers, “clear-sky” Level-2 data (LV2) (profiles atmospheric temperature and humidity) filtered through a radiometer in Beijing during 24 months January 2010 to December 2011 were compared with radiosonde data. Evident differences revealed. Therefore, this paper investigated an approach calibrate observed brightness te...
Due to air quality significantly affects human health, it is becoming increasingly important accurately and timely predict the Air Quality Index (AQI). To this end, paper proposes a new federated learning-based aerial-ground sensing framework for fine-grained 3D monitoring forecasting. Specifically, in air, leverages light-weight Dense-MobileNet model achieve energy-efficient end-to-end learnin...

We apply the sky brightness modelling technique introduced and developed by Roy Garstang to high-resolution DMSP-OLS satellite measurements of upward artificial light flux and to GTOPO30 digital elevation data in order to predict the brightness distribution of the night sky at a given site in the primary astronomical photometric bands for a range of atmospheric aerosol contents. This method, ba...
