The outcome of the assembly elections held in November 2013 in Madhya Pradesh, Rajasthan, Chhattisgarh and Delhi could possibly be summarized in one sentence: Bharatiya Janata Party (BJP) retained Madhya Pradesh and Chhattisgarh, and the incumbent Indian National Congress (INC) lost power in...

The study on dynamics of labour demand in Punjab agriculture has revealed that between 1985-86 and 2006-07, the per-hectare labour use has declined by about 23 per cent; more so, in the case of dominant crops like wheat and paddy that have experienced large-scale mechanization. Wheat and paddy...

A procedure for assessing the techno-economic viability of solar thermal systems in a dynamic economic environment is developed. It is shown analytically that the period for replacement of these systems depends upon the nature of their use. While determining investment viability, it is...

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...
