Genetic-programming prediction of solar-radiation reflectance in cotton woven fabrics for UV–Vis-NIR protection

Fashion and Textiles
This study presented a genetic programming (GP) model for predicting solar-radiation reflectance of cotton woven fabrics as protective materials. The influence of three structural parameters, namely, yarn fineness (14, 25, 36 tex), weave type (plain ...

Study on the Accelerated Aging Test Method in the Development of a Self-Cleaning Topcoat for Cool Roofs

Atmosphere, 2020
The heat island phenomenon in urban areas has become a problem in the recent years. One measure to overcome this, which has been attracting attention, is painting the cool roof with a paint that has high solar reflectance.

Is Ocean Reflectance Acquired by Citizen Scientists Robust for Science Applications?

Remote Sensing, 2018
Monitoring the dynamics of the productivity of ocean water and how it affects fisheries is essential for management. It requires data on proper spatial and temporal scales, which can be provided by operational ocean colour satellites.

Wave Reflection in the Solar Atmosphere

The Astrophysical Journal
Abstract We present evidence supporting wave reflection in the lower solar chromosphere based on helioseismic analysis of multi-height Doppler data from the Solar Dynamics Observatory/Helioseismic and Magnetic Imager and the Magneto-Optical filters at Two Heights II instrument.

Evaluation of reflectance measurement techniques for artificially soiled solar reflectors: Experimental campaign and model assessment

, 2022
The soiling of heliostats is a highly detrimental process that affects the energy conversion efficiency of solar tower power plants as soiled heliostats suffer significant drops of reflectance.
