Post-stack inversion of seismic reflection data from the belvoir coalfield [PDF]

, 1995
Post-Stack inversion of reflection data in seismic exploration can be used to obtain detailed information about lithology variations in the zone of interest. Generalized Linear Inversion (GLI) has previously been applied as a useful tool to achieve this.

Three-dimensional geoacoustic perturbative inverse technique for the shallow ocean water column [PDF]

, 2013
textThis work focuses on developing an inversion scheme to estimate water-column sound-speed fields in three dimensions. The inversion scheme is based on a linearized perturbative technique which utilizes estimates of modal travel times.

Deterministic Transferable Planar Dielectric Mirrors for Investigating Strong Light–Matter Coupling

Advanced Optical Materials, EarlyView.
Transferable dielectric distributed Bragg reflectors enable the deterministic assembly of high‐quality planar microcavities while maintaining the intrinsic properties of quantum materials during fabrication. The resulting structures exhibit robust exciton‐photon coupling in monolayer WS2${\rm WS}_{2}$ from cryogenic to room temperature, establishing a ...

Cross-Gradient Constrained Joint Inversion of Seismic Impedance and Resistivity

Applied Sciences
Individual geophysical inversions reflect only limited physical parameters of the subsurface and often suffer from non-uniqueness. Joint inversion of different geophysical datasets can mitigate this problem by integrating complementary information.

Nonlocomotory Robotic Strategies for Dynamic Rotation Control in Terrestrial Robots: A Review

Advanced Robotics Research, EarlyView.
Terrestrial robots increasingly require rapid body rotation to maintain stability and agility in complex environments. This review shows nonlocomotory rotational control strategies that operate without ground contact, including reaction wheels, tails, bars, limbs, and thrusters.

Model Fusion and Joint Inversion

, 2020
Inverse problems are inherently non-unique, and regularization is needed to obtain stable and reasonable solutions. The regularization adds information to the problem and determines which solution, out of the infinitely many, is obtained.

Identifying seawater intrusion in coastal areas by means of 1D and quasi-2D joint inversion of TDEM and VES data

, 2017
Seawater intrusion is an increasingly widespread problem in coastal aquifers caused by climate changes –sea-level rise, extreme phenomena like flooding and droughts– and groundwater depletion near to the coastline.

Multimodal Locomotion in Insect‐Inspired Microrobots: A Review of Strategies for Aerial, Surface, Aquatic, and Interfacial Motion

Advanced Robotics Research, EarlyView.
This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.
