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 ...

Design Concept for a Future Super Proton-Proton Collider
Frontiers in Physics, 2022 Following the discovery of the Higgs boson at the LHC in 2012, new large colliders are being considered and studied by the international high-energy community to explore the Higgs boson in details and to probe new physics beyond the Standard Model.

Luminosity–time and luminosity–luminosity correlations for GRB prompt and afterglow plateau emissions [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 We present an analysis of 123 Gamma-ray bursts (GRBs) with known redshifts possessing an afterglow plateau phase. We reveal that $L_a-T^{*}_a$ correlation between the X-ray luminosity $L_a$ at the end of the plateau phase and the plateau duration, $T^*_a$, in the GRB rest frame has a power law slope different, within more than 2 $σ$, from the slope of ...

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 ...

0224 "The Image of Adam’s Glory"
RIHA Journal, 2019 The imagery of the "radiant body" and "luminous garment" occurs frequently in early Christian references to the Edenic state of Adam and its partial reinstatement by Moses, Jesus, and numerous saintly (usually ascetic) figures.

K-corrections: an Examination of their Contribution to the Uncertainty of Luminosity Measurements
The Open Journal of Astrophysics, 2016 In this paper we provide formulae that can be used to determine the uncertainty contributed to a measurement by a K-correction and, thus, valuable information about which flux measurement will provide the most accurate K-corrected luminosity. All of this
