Distribution power loss minimization via optimal sizing and placement of shunt capacitor and distributed generator with network reconfiguration
The population is speeding up and the demands for electrical energy are clearly
increasing, this growth in load leads to higher power loss and Voltage drop.
This paper is focused on a method to decrease the power losses and voltage
profile…

Biomass estimation model for peat swamp forest ecosystem using light detection and ranging
Peat swamp forest plays a very important role in absorbing and storing large
amounts of terrestrial carbon, both above ground and in the soil. There has
been a lot of research on the estimation of the amount of biomass above the
ground, but a…

MgCeAl11O19:Tb3+ and Mg8Ge2O11F2:Mn4+ in enhancing the color quality of remote phosphor LED
As the name infers, the triple-layer remote phosphor (TRP) has 3 phosphor
layers includes the red Mg8Ge2O11F2:Mn4+ phosphor layer on the top, the
green MgCeAl11O19:Tb3+ phosphor layer in the middle, and the yellow
YAG:Ce3+ layer at the bottom and…

Investigation on the application of ZnO nanostructures to improve the optical performance of white light-emitting diodes
Though combining blue LED chips with yellow phosphor has been the most
common method in white light-emitting diode (WLED) production, the
attained angular correlated color temperature (CCT) uniformity is still poor.
Thus, this article proposes to…

Enhancement of luminous flux and color quality of white
light-emitting diodes by using green (Y,Gd)BO3:Tb3+ phosphor
In the study, we analyzed and clarified the effect of green (Y,Gd)BO3:Tb3+
phosphor on chromatic homogeneity and optical performance of multi-chip
white light emitting diodes (MCW-LEDs). Thereby there is a solution to get
the best luminous…

The impacts of red-emitting phosphor Mg8Ge2O11F2:Mn4+ on the color rendering index of convex-dual-layer remote phosphor WLEDs at 5600 K
The poor color rendering index (CRI) induced by mono chip and phosphor
configuration in the conventional white-light light-emitting diode (LED)
urges for developments in both packaging and material, thus, a modern
lighting solution was introduced.…

Time series analysis of electric energy consumption using autoregressive integrated moving average model and Holt Winters model
With the increasing demand of energy, the energy production is not that much
sufficient and that’s why it has become an important issue to make accurate
prediction of energy consumption for efficient management of energy. Hence
appropriate demand…
