Uncertainties in local solar radiation, ambient temperature and thermal load data have been one of the major factors limiting the reliability and efficiency of solar thermal hybrid systems. In the present paper, moving average auto regressive exogenous (ARX) model based reasoning has been mooted...

A wind driven aspirator was integrated with a solar distillation system to produce a regenerative effect. The system is analysed on the basis of energy balance for its different components. Analytical expressions are derived for water and glass temperatures, daily yield and thermal efficiency as...

Tools available for energy conservation in buildings still lack practical and cost-effective fault detection and diagnosis technique. This paper puts forth model based fault detection technique for off-line analysis based upon Autoregressive Exogenous method. Real time operation data of a...

We have studied an active solar distillation system during peak summer days. The system is made of fibre-reinforced plastic (FRP) and is coupled to a flat-plate collector (FPC). Performance of single and double-effect solar distillation, with and without water-flow over the glass cover, was...

The present work deals with the analysis of the quasi-particle spectrum and the density of states of monolayer and bilayer (AB- and AA-stacked) graphene. The tight binding Hamiltonian containing nearest-neighbor and next-nearest neighbor hopping and onsite Coulomb interaction within two...

For estimation of runoff response of an ungauged catchment resulting from a rainfall event, geomorphologicalinstantaneous unit hydrograph (GIUH) approach is getting popularbecause of its direct application to an ungauged catchment. Itavoids adoption of tedious methods of regionalization of...

Single phase FeTi intermetallic and FeTi-3.1 mass % V alloy were synthesized by vacuum arc melting using high purity elemental constituents. The crystal structure of both, FeTi intermetallic and FeTi-3.1 mass % V alloy was found to be of CsCl-type. Under similar annealing conditions, crystallite...
