Hyperspectral Inversion Model of Relative Heavy Metal Content in Pennisetum sinese Roxb via EEMD-db3 Algorithm

open access: yesRemote Sensing, 2023
Detection rapidity and model accuracy are the keys to hyperspectral nondestructive testing technology, especially for Pennisetum sinese Roxb (PsR) due to its extremely high adsorptive heavy metal content.

Littlest inverse seesaw model

open access: yesNuclear Physics B, 2020
We propose a minimal predictive inverse seesaw model based on two right-handed neutrinos and two additional singlets, leading to the same low energy neutrino mass matrix as in the Littlest Seesaw (LS) (type I) model. In order to implement such a Littlest Inverse Seesaw (LIS) model, we have used an $S_{4}$ family symmetry, together with other various ...

Adaptive waveform inversion: theory [PDF]

open access: yes, 2016
Conventional full-waveform seismic inversion attempts to find a model of the subsurface that is able to predict observed seismic waveforms exactly; it proceeds by minimizing the difference between the observed and predicted data directly, iterating in a ...

Research on Inversion Model of Cultivated Soil Moisture Content Based on Hyperspectral Imaging Analysis

open access: yesAgriculture, 2020
Based on hyperspectral imaging technology, rapid and efficient prediction of soil moisture content (SMC) can provide an essential basis for the formulation of precise agricultural programs (e.g., forestry irrigation and environmental management).

Measuring the Optical Properties of Highly Diffuse Materials

open access: yesSensors, 2023
Measuring the optical properties of highly diffuse materials is a challenge as it could be related to the white colour or an oversaturation of pixels in the acquisition system.

Tomographic inversion of time-domain resistivity and chargeability data for the investigation of landfills using a priori information [PDF]

open access: yes, 2017
In this paper, we present a new code for the modelling and inversion of resistivity and chargeability data using a priori information to improve the accuracy of the reconstructed model for landfill.

Acoustic properties of fine‐grained sediments from Emerald Basin: Toward an inversion for physical properties using the Biot–Stoll model [PDF]

open access: yes, 1993
Acoustic data from two long cores, comprising marine clays and silts taken from Emerald Basin off Nova Scotia, are presented. High‐resolution measurements of compressional wavevelocity,attenuation, and power law exponent are made using ultrasonic ...

Calculating Electrical Conductivity of Soil Using Electromagnetic Induction Data

open access: yesGuan'gai paishui xuebao, 2021
【Background】 Along with drought, soil salinization is one of the most important abiotic stresses facing agricultural production in arid and semi-arid regions like Xinjiang in northwest China.
