Estimation of Chargeability and Permeability using Spectral Induced Polarization Data

Induced polarization (IP) method has been successfully implemented in investigation of groundwater, geothermal and metallic ores. From published (Nordsiek and Weller, 2008) spectral induced polarization (SIP) data, the amplitude and phase spectra have been derived. Frequencydependent impedance data sets have been calculated from these SIP data sets, which were derived for chargeability by Debye...

Large Scale Experiments Data Analysis for Estimation of Hydrodynamic Force Coefficients Part 1: Time Domain Analysis

This paper describes various time-domain methods useful for analyzing the experimental data obtained from a circular cylinder force in terms of both wave and current for estimation of the drag and inertia coefficients applicable to the Morison’s equation. An additional approach, weighted least squares method is also introduced. A set of data obtained from experiments on heavily roughened circul...

Propagation-induced Circular Polarisation in Synchrotron Sources

The small degree of circular polarisation observed in some synchrotron sources has a frequency dependence that is not consistent with simple predictions based on the intrinsic circular polarisation of synchrotron emission. The suggestion is explored that the circular polarisation arises as a propagation effect within the source. The physical basis of this alternative mechanism is the fact that ...

Reliability Models Data Domain Time Domain Homo

A number of software reliability models have been proposed for assessing the reliability of a software system. In this paper, we discuss the time-domain and data-domain approaches to software reliability model-ing, and classify the previously reported models into these two classes based on their underlying assumptions. The data-domain models are further classiied into fault-seeding and input do...
