An improved characterisation of the unsteady hydrodynamic loads on tidal turbine blades is necessary to enable more reliable predictions of their fatigue life and to avoid premature failures. To this end, this paper presents a set of blade-root bending moment responses for a scale-model tidal...

In operating a complex hydroelectric system in a competitive market the operational as well as the financial risks are high. Decision makers and operators unarmed with rigorous analysis tools and techniques could cause their organization to pay dearly for their decisions. Traditionally the main...

A smart wind turbine concept with variable length blades and an innovative hybrid mechanical–electrical power conversion system was analyzed. The variable length blade concept uses the idea of extending the turbine blades when wind speeds fall below rated level, hence increasing the swept...

Over a century back, while commenting on the rapid urbanisation process in Europe, the great philosopher and sociologist in Marxist tradition, Lefebvre (1996, p.119) had stated that "the expanding city attacks the countryside, corrodes and dissolves it". In Indian context, the above statement...

India’s urban planning, in terms of a balanced approach towards dispersal of economic activity and deflection of swelling population away from a few ‘economically strategic’ mega-cities, has by and large been a non-starter. Five Year Plans, though paid lip-service to such a strategy, never...
