Signal-to-Noise Ration Evaluation of Luojia 1-01 Satellite Nighttime Light Remote Sensing Camera Based on Time Sequence Images [PDF]
, 2019 Signal-to-noise ratio (SNR) is an important index to evaluate radiation performance and image quality of optical imaging systems under low illumination background. Under the nighttime lighting condition, the illumination of remote sensing objects is low and varies greatly, usually ranging from several lux to tens of thousands of lux.

Augmented LT codes over binary extension fields with increased ratio of full‐degree columns
Electronics Letters, Volume 60, Issue 5, March 2024.An augmented scheme of LT codes is proposed to improve the decoding success rate. The method involves substituting the 1 in full‐degree columns of the generator matrix of conventional LT codes with binary extension field elements and simultaneously increasing the ratio of full‐degree columns in the ideal soliton distribution, which allows for higher ...

Earth and Space Science, Volume 11, Issue 2, February 2024.Abstract The Green's function approach is well‐established and widely used for modeling the surface mass loading displacements. Global mean Green's functions (MGFs) are commonly applied without considering local variations of the crustal structure. Derived from the modified layered Earth structure, the local Green's functions (LGFs) are theoretically ...

Noncommutative resolutions of ADE fibered Calabi-Yau threefolds [PDF]
, 2010 In this paper we construct noncommutative resolutions of a certain class of Calabi-Yau threefolds studied by F. Cachazo, S. Katz and C. Vafa. The threefolds under consideration are fibered over a complex plane with the fibers being deformed Kleinian ...

Downscaling NPP–VIIRS Nighttime Light Data Using Vegetation Nighttime Condition Index
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingNighttime light (NTL) data, a cornerstone in the scientific community, are widely used across various disciplines. However, the spatial resolution of the commonly used NTL datasets often falls coarse for detailed urban-scale analyses. Current downscaling
