Engineering uses the chloride ion diffusion coefficient as the durability of concrete quality control indicators under the marine environment, due to the chloride ion diffusion coefficient and the electrical resistivity of concrete parameters are reflected in the concrete pore structure, and resistivity testing is convenient, fast advantages, the resistivity alternative chloride ion diffusion c...

Fluctuations of resistivity have been monitored with an array measuring natural electric currents (telluric currents) in Parkfield. This array is designed to detect short-term relative changes of resistivity of 1% over days to weeks and long-term variations of 0.1% over months to years. Fractional daily variations of the telluric coefficients are computed and then compared to the earthquake rec...

This paper presents the fabrication, modeling, characterization and analysis of silicon-embedded, aircore, three-dimensional toroidal inductors for power converter applications. The inductors are fabricated within deep silicon recesses by means of a 3-D silicon shadow mask coupled with electroplating techniques. The losses in the inductor and the surrounding silicon are analytically modeled usi...

Magnetization and Hall resistivity have been investigated for single crystals of Dy-doped Nd2Mo2O7. A sharp decrease of the Hall resistivity upon a metamagnetic transition, perhaps associated with magnetic-field (H) induced flop of Dy moments, has been observed in the Dy-doped crystals only for H ‖ [111] direction. In addition, the sign of the Hall resistivity at a high field, both for H ‖ [100...

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 ...

2014 The thickness, d, dependence of the extraordinary (R1) and spontaneous (Rs) Hall coefficients of iron films was studied in the range 100-1 000 Å. The R1.a and Rs.a versus a curves exhibit a straight line behaviour; this is interpreted in terms of size effects in the total film resistivity in agreement with some theoretical studies on the Hall effect in bulk ferromagnetics which have predic...

The goal of this paper is to introduce and design a cost-effective Oil-in-Water (OiW) measuring instrument, which will be investigated for its value in increasing the efficiency of a deoiling hydrocyclone. The technique investigated is based on Electrical Resistivity Tomography (ERT), which basic principle is to measure the resistivity of substances from multiple electrodes and from these measu...
