Computation of Analytical Derivatives for Airborne TEM Inversion Using a Cole–Cole Parameterization Based on the Current Waveform of the Transmitter

open access: yesSensors, 2022
Airborne transient electromagnetic (ATEM) technology is a technique often used in mineral exploration and geological mapping. Due to inductive polarization (IP) phenomena, the ATEM response curve often shows a negative response or declines rapidly to the

Analyse de la composante sémantique lexicale de l’inversion locative en anglais

open access: yesE-REA, 2013
This article examines the noncanonical structure known as the locative inversion, which can be described as : < Constituent1 C1 (fronted locative expression) + verb V + Constituent2 C2 (postposed subject) >.

Estimation of Impact Load by Inverse Analysis : Optimal Transfer Function for Inverse Analysis

open access: yesJSME international journal. Ser. 1, Solid mechanics, strength of materials, 1991
The present study is concerned with a method for estimating impact load acting on a body of arbitrary shape. It is known that the impact load can be estimated from the impact response of the body by an inverse analysis. In practical situations, the impact response data involves noise caused by the measurement system.

Propagator and wave-equation inversion for near-receiver material properties [PDF]

open access: yes, 2004
Near-receiver material properties are required for the separation of the recorded wavefield into upgoing and downgoing P and S waves, and are also important for static time-shift corrections.

Determination of gas reservoir(s) using AVO inversion within “XY” field offshore Niger Delta

open access: yesPetroleum Research, 2019
The AVO inversion analysis of pre-stack seismic data of “XY” field located within the offshore, Niger Delta Basin has been considered in this research work with the aim of using AVO inversion to delineate gas reservoirs within the field.
