Research ArticleOpen accessIn the keywordsInvestigations of Two-Layer Earth Parameters at Low Voltage: Measurements and CalculationsRamdan E. Rajab, N. Mohamad Nor, K. RamarProblem statement: The two-layer soil model at low magnitude voltage is assumed to be accurate for the measurement and calculation of the earth resistance of a combined grid-multiple rods electrode. The aim of this study is to measure and calculate the earth resistance of a combined grid-multiple rods electrode buried in a two-layer soil and to confirm the simplicity and … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 7,816 accessesView PDFCite
Research ArticleOpen accessIn the keywordsValidation of the Calculation and Measurement Techniques of Earth Resistance ValuesN. Mohamad Nor, R. Rajab, K. RamarMuch research has been published in the literature on the mathematical approaches to obtain the most accurate earth resistance and resistivity values. However, the published research only conducted the comparisons among the mathematical/computational techniques and so far none has conducted validation tests of these mathematical/computational methods against the real earth resistance measurement at real field sites. Thus, the main contribution … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,214 accessesView PDFCite

Research ArticleOpen accessIn the abstractElectrical and Magnetoresistive studies Nd doped on La-Ba-Mn-O3 Manganites for Low-field Sensor applicationH. Abdullah, S. A. HalimProblem Statement: Electrical and magnetoresistive properties of the Nd doped (La1-xNdx)0.5Ba0.5MnO3 type samples with 0 ≤ x ≤ 1.0 had been prepared using the solid state reaction. These materials are extensively studied by the substitution of rare-earth compound is to understand the nature of transport phenomena in each system. Approach: The samples were calcined at 900°C for 12 h, pelletized … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,663 accessesView PDFCite
