Sustainable urbanization using high speed rail (HSR) in Karnataka, India
Sustainable urbanization using high speed rail (HSR) in Karnataka, India.
Phase transition, electrochemistry, and structural studies of high rate Lix V3O8 cathode with nanoplate morphology
Structural and kinetic behavior of lithium-vanadium-oxide (LixV3O8) cathode is studied as lithium-ion battery electrode. The morphology of LixV3O8is found to be nanoplates with nanorods as minor constituents.
Infiltration velocity and thickness of flowing slag film on porous regractory of slagging gasifiers
Two analytical formulations that describe the fluid interactions of slag with the porous refractory linings of gasification reactors have been derived. The first formulation considers the infiltration velocity of molten slag into the porous microstructure of the refractory material that possesses an inherent temperature gradient in the direction of infiltration. Capillary pressures are assumed to be the primary driving force for the infiltration.
Analytical derivation of explicit J-V model of a solar cell from physics based implicit model

Analytical derivation of equivalent functional form of explicit J–V model of an illuminated solar cell from physics based implicit model
Recently a simple explicit model was introduced to represent theJ–Vcharacteristics of an illuminated solar cell with parasitic resistances and bias dependent photocurrent asj=(1−vm)/(1+αv), here the normalized voltage,vand normalized current densityjcan be represented asv=V/V
An empirical model of power curve of a wind turbine
The power curve of a wind turbine grows exponentially as a function of wind-velocity if the measured wind-velocity varies between the cut-in velocity and the rated velocity. In this study, we propose an empirical, two-parameter explicit model of the power curve for a wind turbine. The model generalizes different turbine power curves and provides an easy estimate to compare various turbine characteristics.
Comparative Techno-Economic Analysis of Rooftop PV (RTPV) Systems in Various States in India
The growth of RTPV has been sluggish compared to ground-mounted installations. This study analyses the techno-economics of RTPV in different states with their respective net-metering (NM)/gross-metering (GM) regulations and state policies to assess the financial performance of RTPV systems. States having abundant amount of solar potential such as Karnataka, Gujarat, Rajasthan, Maharashtra and Tamil Nadu are considered. The results of this analysis show that there is a lack of favourable consumer-end economics indicated by equity Internal Rate of Return (IRR) and payback period findings.
