Mapping full seismic waveforms to vertical velocity profiles by deep learning

Subsurface Imaging with Reverse Vertical Seismic Profiles

A novel imaging process, referred to as vector image isochron (VII) migration, is specifically designed to reduce artifacts caused by arrays with limited apertures. By examining the assumptions behind generalized Radon transform (GRT) migration, a new approach is found which identifies and suppresses array artifacts, based on the array geometry and the migration earth model. The new method work...

The Seismic Response to Strong Vertical Velocity Change

Analysis of seismic waveforms using full-bridge voltage source inverter

The current research talks about a designed accelerometer system which is able to measure every type of mechanical vibration. The applied vibration in this survey is called seismic wave. Then the measured wave by this novel system is transf ormed to a specif ic function using spline interpolation. This explicit function can be used as a reference signal in the technique PWM to be made in curren...

Velocity continuation in the downward continuation approach to seismic imaging - 909.full

S U M M A R Y One way of developing a wave-equation approach to seismic imaging is based on the concept of downward continuation of observed surface reflection data. Seismic imaging is typically based on the single scattering approximation, and assumes the knowledge of a smooth background model in which the mentioned downward continuation is carried out using the double-squareroot (DSR) equatio...

Mapping Waveforms to Mobile Parallel Processor Architectures

Portable software defined radio solutions for the consumer market will be based on mobile devices employing multiple programmable processing resources, as low power consumption needs to be maintained for an acceptable battery life. Therefore the designer needs to orchestrate the given system functions of the waveform efficiently onto the dis tributed processing resources. For the automation or ...
