Dynamic Earthquake Source Inversion With Generative Adversarial Network Priors
Abstract Dynamic earthquake source inversion consists of inferring frictional parameters and initial stress on a fault consistent with recorded seismological and geodetic data and with dynamic earthquake rupture models. In a Bayesian inversion approach, the nonlinear relationship between model parameters and data requires a computationally demanding ...

How to Be Hopeful About Climate Change
ABSTRACT Why do people in climate‐vulnerable regions of Kenya and Namibia express more hope for the future than many in Germany, despite facing greater environmental threats? Drawing on ethnographic research and the philosophy of Gabriel Marcel, we make two arguments.

Numerical Simulation of Nanofluid Suspensions in a Geothermal Heat Exchanger
It has been shown that using nanofluids as heat carrier fluids enhances the conductive and convective heat transfer of geothermal heat exchangers. In this paper, we study the stability of nanofluids in a geothermal exchanger by numerically simulating ...

Estimation of borehole heat exchanger thermal properties [PDF]
An important issue in the design of installations with borehole heat exchangers (BHE) is knowledge of the thermo-physical properties of the grouting material and soil. The objectives of this work is to estimate the thermal conductivity and specific heat of the grouting material and the soil.

Near Field Investigation of Borehole Heat Exchangers
As an alternative and renewable energy source, the shallow geothermal energy evolving as one of the most popular energy source due to its easy accessibility and availability worldwide, and the ground source heat pump (GSHP) systems are the most frequent applications for extracting the energy from the shallow subsurface.
