We calculate the flux flow resistivity in a superconductor with multiple s-wave superconducting gaps. Our result agrees well with anomalous field dependence of the resistivity recently observed in the two-gap superconductor MgB2.

An automatic technique is developed for integrating two electrical resistivity logs obtained during Leg 133, namely, the deep induction log (ILD) and the spherically focussed log (SFL). These logs are routinely run by the Ocean Drilling Program in lower resistivity sedimentary environments, where drilling through soft, poorly consolidated lithologies often results in variable hole diameters. Ex...

A brief summary of the importance of the electrical resistivity of rocks in geothermal exploration is given as well as some of its is main relationships with some of the characteristics of geothermal reservoirs. Special emphasis is on the resistivity of rocks in high temperature geothermal fields where the dominant factor is the hydrothermal mineral alteration and how it relates to temperature....

It is known that the three important parameters: resistivity, capillary pressure, and relative permeability, are all a function of fluid saturation in a porous medium. This implies that there may be a correlation among the three parameters. There have been many papers on the approach to inferring relative permeability from capillary pressure data. However the literature on the interrelationship...

In their recent paper, Roberts et aL (1979) report the following values of intracellular (i), extracellular (o), longitudinal (<f), and transverse (t) resistivity for canine ventricular muscle: r^ = 450 ohms-cm, rot = 750 ohm-cm, ru = 360 ohm-cm, and rit = 3800 ohm-cm. The ratio W r ^ is 1.67. In an earlier paper, Clerc (1976) reported the following resistivity ratios for trabecular bundles fro...

The magnetotelluric method has improved significantly in recent years and is being used in hydrocarbon exploration in regions where seismic exploration is difficult. This includes areas where highvelocity carbonates and volcanic rocks are present in the near surface, overthrust belts, and in subsalt imaging. Magnetotelluric exploration was used in the Rocky Mountain Foothills in 2002 to determi...

Multi-view face animation is widely required in various applications nowadays, but most of existing relative techniques have burdensome computational load in data registration, model construction and animation. Addressing those problems, this paper proposes an efficient approach via employing quasi 3D model, which is the fusion of a 3D geometry model with 2D facial textures. 3D Point Distribute...

We have developed a new data acquisition system and technique to measure the radio magnetotelluric (RMT) signals from distant radio transmitters with the objective of mapping and modeling electric resistivity structures below a river or lake. The acquisition system is towed by a boat; therefore, we call the technique boat-towed RMT. The data acquisition is fast with a production rate of approxi...

In this study, geophysics, geochemistry, and geostatistical techniques were integrated to assess seawater intrusion in Kapas Island due to its geological complexity and multiple contamination sources. Five resistivity profiles were measured using an electric resistivity technique. The results reveal very low resistivity <1 Ωm, suggesting either marine clay deposit or seawater intrusion or both ...
