Within ghost hunting and parapsychology, electronic voice phenomena (EVP) are sounds found on electronic recordings that are interpreted as spirit voices.

What is EVP? Electronic Voice Phenomenon (EVP) are intelligible voices found in recording media that have no known physical explanation. Many of the voices are thought to originate from deceased people.

Nov 1, 2013 · The EVP method is based on subcycling iterations during which the ice velocities and internal stresses are successively updated towards the solution of the non-linear VP equations. Relaxation terms, also called regularization terms, are introduced to avoid instabilities.

EVP are complete words or phrases – Message are typically one to two seconds in duration and are not truncated at the beginning or end. If EVP were radio interference, they would often begin in the middle of a word. EVP messages are usually complete thoughts, as well.

In this paper, we show that one of the most widely used methods to solve the non-linear viscous–plastic (VP) sea ice rheology, the elastic–viscous–plastic (EVP) method, generates artificial linear bands of high deformation that may be confounded with real linear kinematic features observed in the Arctic ice pack.

Sep 1, 2015 · The elastic–viscous–plastic (EVP) method is an alternative to implicit methods. It relaxes the time step limitation of the explicit VP method by introducing an additional elastic term to the stress equations.

The Elastic-Viscous-Plastic method (EVP) is revisited as a non-linear solver dedicated to the Viscous-Plastic dynamics model (VP). A clear distinction appears between the physical parameters of the model and the numerical parameters. Two numerical parameters control the stability and the conver-gence rate of the solver.

Sep 22, 2020 · The proposed 3D EVP model incorporates shear yield criterion, non-associated flow rule, and strain-hardening law, which makes it possible for the model to describe the rate effects and shear dilation characteristic.
