Numerical modelling of reservoir sedimentation for sustainable storage capacity – a geospatial approach

Geology, Ecology, and Landscapes, 2022
Surface water change is a very important indicator for environmental, climatic, and anthropogenic activities. The sediment brought by the stream into the reservoir starts settling down and gets deposited on the bed of the reservoir at all levels.

A Triangulated Irregular Network Constrained Ordinary Kriging Method for Three-Dimensional Modeling of Faulted Geological Surfaces

IEEE Access, 2020
Three-dimensional (3D) modeling of geological surfaces, such as coal seams and strata horizons, from sparsely sampled data collected in the field, is a crucial task in geological modeling.

Relationships among Interpolation Bases of Wavelet Spaces and Approximation Spaces [PDF]

, 2012
A multiresolution analysis is a nested chain of related approximation spaces.This nesting in turn implies relationships among interpolation bases in the approximation spaces and their derived wavelet spaces.

Necessary Density Conditions for Sampling and Interpolation of Certain Entire Functions with Doubling Weights

Axioms
Let Λ⊆Rd be a discrete uniformly separated subset. In the unweighted case and p=2, Landau obtained the necessary conditions for sampling and interpolation of functions in Paley–Wiener space in terms of the upper and lower uniform densities of Λ.

Triangle-Mesh-Rasterization-Projection (TMRP): An Algorithm to Project a Point Cloud onto a Consistent, Dense and Accurate 2D Raster Image

Sensors, 2023
The projection of a point cloud onto a 2D camera image is relevant in the case of various image analysis and enhancement tasks, e.g., (i) in multimodal image processing for data fusion, (ii) in robotic applications and in scene analysis, and (iii) for ...

ODEI: Object Detector Efficiency Index

AI
Object detectors often rely on multiple metrics to reflect their accuracy and speed performances independently. This article introduces object detector efficiency index (ODEI), a hardware-agnostic metric designed to assess object detector efficiency ...

Comparison of Methods for Reconstructing MODIS Land Surface Temperature under Cloudy Conditions

Applied Sciences, 2022
Land surface temperature (LST) is a vital parameter associated with the land–atmosphere interface. The Moderate Resolution Imaging Spectroradiometer (MODIS) LST product can provide precise LST with high time resolution, and is widely applied in various ...

Some remarks on non-symmetric interpolation Macdonald polynomials

, 2019
We provide elementary identities relating the three known types of non-symmetric interpolation Macdonald polynomials. In addition we derive a duality for non-symmetric interpolation Macdonald polynomials.
