Determination of the sky conditions in Shah Alam, Malaysia and modelling the zenith luminance / Noorhasimah Yeop by Yeop, Noorhasimah

“…From this plot, it showed that the zenith luminance increased when the solar altitude increased at noon time. Zenith luminance values are important in terms of light source efficacy and when integrated with electric lightning in commercial building that could reduce energy and power consumption (Junsiri et al.2012).From the graph of zenith luminance, the polynomial equation was produced by using a curve fitting toolbox from origin where Lz = 0.02 a2 - 0.038a + 1.005 and the coefficient of determination (R2) is 0.969. …”

Empirical characterization of equatorial geomagnetically induced currents (GICs) due to space electromagnetic perturbations / Farah Adilah Mohd. Kasran by Mohd. Kasran, Farah Adilah

“…The results also deduced that higher number of strong equatorial dB/dt happened during local noon and it has a strong correlation with the solar wind dynamic pressure, Pdyn. …”
