We present a nodal finite-element method that can be used to compute in parallel highly accurate solutions for 3-D controlled-source electromagnetic forward-modelling problems anisotropic media. Secondary coupled-potential formulation of Maxwell's equations allows avoid the singularities introduced by sources, while completely unstructured tetrahedral meshes and mesh refinement support an representation geological bathymetric complexity improve solution accuracy. Different complex iterative...
Finite-difference methods for modeling seismic waves are known to be inaccurate when including a realistic topography, due the large dispersion errors that appear in modelled surface and scattering introduced by staircase approximation topography. As consequence, alternatives finite-difference have been proposed circumvent these issues. We present new numerical scheme 3D elastic wave propagation presence of strong This is based upon staggered grid Lebedev type, or fully (FSG). It uses...
The stable propagation of jets in FRII sources is remarkable if one takes into account that large-scale are subjected to potentially highly disruptive three-dimensional (3D) Kelvin-Helmholtz instabilities. Numerical simulations can address this problem and help clarify the causes stability. Following previous studies stability relativistic flows two dimensions (2D), it our aim test extend conclusions such works three dimensions. We present numerical for study properties 3D, sheared, flows....
Oil and gas companies trust Reverse Time Migration (RTM), the most advanced seismic imaging technique, with crucial decisions on drilling investments. The economic value of oil reserves that require RTM to be localized is in order 10^{13} dollars. But requires vast computational power, which somewhat hindered its practical success. Although, accelerator-based architectures deliver enormous little attention has been devoted assess implementations effort. aim this paper identify major...

SUMMARY We present a parallel and high-order Nédélec finite element solution for the marine controlled-source electromagnetic (CSEM) forward problem in 3-D media with isotropic conductivity. Our Python code is implemented on unstructured tetrahedral meshes, which support multiple-scale structures bathymetry general CSEM modelling applications. Based primary/secondary field approach, we solve diffusive form of Maxwell’s equations low-frequency domain. investigate accuracy performance...
<div> <p>The structure of the wind turbines nowadays is a critical element due to their importance from reliability, availability, safety, and cost points view. This more relevant when offshore turbine considered. paper introduces novel design Fault Detection Diagnosis (FDD) model based on ultrasound technique. The FDD will be able detect fault/failures via pulse-echo got piezoelectric transducers that are also employed as sensors. signal processing two steps. Firstly, wavelet...
In this paper, we evaluate the error criticality of radiation-induced errors on modern High-Performance Computing (HPC) accelerators (Intel Xeon Phi and NVIDIA K40) through a dedicated set metrics. We show that, as long imprecise computing is concerned, simple mismatch detection not sufficient to compare radiation sensitivity HPC devices algorithms. Our analysis quantifies qualifies effects applications' output correlating number corrupted elements with their spatial locality. Also, provide...
The present study was conducted to understand the socio-economic profile of innovative farmers in Telangana, India, using an ex-post-facto research design. A total 180 were purposively selected from three agro-climatic zones, with data collected through structured interviews and analyzed cumulative square root frequency method. Majority (61.11%) belonged middle-aged group (36 50 years), most (25.00%) had completed secondary school, 43.33% owning medium-sized holdings, 45.00% fell into low...
