Three-dimensional inversion of inductions logs in real-time

Bensdorp, S. (author)

In petroleum production and exploration, having good information about a hydrocarbon reservoir is paramount to successful exploitation. A popular tool is to probe the electric conductivity in a well to obtain direct information of the well surrounding. As wells are nowadays mostly horizontally drilled, this information is becoming more important...

Seismic Broadband Full Waveform Inversion by shot/receiver refocusing

Haffinger, P.R. (author)

Full waveform inversion is a tool to obtain high-resolution property models of the subsurface from seismic data. However, the technique is computationally expens- ive and so far no multi-dimensional implementation exists to achieve a resolution that can directly be used for seismic interpretation and characterisation. In this thesis we discuss a...

Modeling of nonlinear medical diagnostic ultrasound

Huijssen, J. (author)

In this PhD Thesis, a numerical method is described that accurately predicts the pulsed acoustic pressure field generated by a medical diagnostic phased array transducer in a nonlinear acoustic medium. The method is called the Iterative Nonlinear Contrast Source (INCS) method, and it is capable of handling a large-scale, threedimensional domain...

Integrated field equations methods for the computation of electromagnetic fields in strongly inhomogeneous media

Jorna, P. (author)

Electromagnetic field theory plays a very important role in present-day technology; examples of technologies based on electromagnetism that are inextricably bound up with every day life are: radar, remote sensing, geoelectromagnetics, bioelectromagnetics, antennas, wireless communication, optics, high-frequency circuits, and so on. In order to...

Electrodynamics in deformable solids for electromagnetic forming

Motoasca, T.E. (author)

The behaviour of matter in an electromagnetic field may be considered as a very complex problem, involving not only electromagnetism but also mechanics and thermodynamics. The interaction field-matter is not simple even for a rigid body, and it becomes more complicated for a deforming body, as long as all the physical quantities that...

A Seismic Transmission System for Continuous Monitoring of the Lithosphere: A Proposition

Unger, R. (author)

The main objective of this thesis is to enhance earthquake prediction feasibility. We present the concept and the design layout of a novel seismic transmission system capable of continuously monitoring the Lithosphere for changes in Earth physics parameters governing seismic wave propagation. New-technology seismic vibrator sources (magnetic...
