International Scientific Indexing (ISI)

A computer program in C++ language has been developed to calculate cube roots of nuers from 1 to 25 in interval [1, 3] using bisection method. Rate of convergence has been found out in each calculation. Lowest rate of convergence has been observed in the evaluation of cube root of 18 and highest in the evaluation of cube root of 9.

Cable Steady-State Temperature Calculation | Cable Thermal

The Steady-State Cable Temperature calculation determines the temperature of all the cable conductors involved in the raceway system under a specified loading condition. The calculation is based on the IEC 60287 standard or the NEC accepted Neher-McGrath approach, which employs a thermal circuit model to represent heat flow situations.

Structural, microstructural and dielectric properties of

The synthesized powders whose chemical formula is (Ba 1 xLa x)Tið1 x=4ÞO 3, were elaborated using the sol gel process through the destabilization of colloidal solution (DCS) method, and were calcined at 900 C for 3h before sintering at 1250 C for 6h. The data extracted from dielectric measurements has been used to calculate and analyze the AC

X-ray Studies and Electrical Properties of the Zinc

May 06, 2015· The structural and dielectric properties were studied for Zn substituted copper spinel ferrite having the formula Cu 1-x Zn x Fe 2 O 4 where [x = 0.0, 0.2, 0.4, 0.6, 0.8, and 1.0]. This ferrite prepared by an auto-coustion sol-gel method and calcined at different temperatures (500, 800, and 1100°C). The X-ray diffraction pattern of these compositions showed the formation of the single phase
