Characterizing the luminosity components of luminous infrared galaxies in multi-wavelength from the X-ray to the far-infrared [PDF]
Scientific ReportsWe characterize luminosity components of Ultra/Luminous Infrared Galaxies (U/LIRGs) in multi-wavelength from the X-ray to far-infrared. A set of 63 AGN U/LIRGs was selected where these galaxies are powered by a central active galactic nucleus (AGN ...

Periphytic algae biomass at different shading levels: an experimental approach
Acta Limnologica Brasiliensia, 2021 : Aim Light is an essential component in the process of synthesis of organic compounds by photosynthetic organisms. Assuming that a higher level of luminosity would positively influence the production of biomass, we evaluated the influence of different ...

A Novel Luminance-Based Algorithm for Classification of Semi-Dark Images
Applied Sciences, 2021 Image classification of a visual scene based on visibility is significant due to the rise in readily available automated solutions. Currently, there are only two known spectrums of image visibility i.e., dark, and bright.

Luminosity and Contrast Adjustment of Fundus Images with Reflectance
Applied Sciences, 2023 This paper presents an automatic correction method for luminosity and contrast variation in fundus images. Sixty retina or fundus images with different levels of reflectance are selected from online databases and used to assess the effectiveness of the ...
