in this research, the energy flow and production energy indices of canola cultivation in trakya province of turkey, golestan and mazandaran provinces of iran were compared. diesel fuel and chemical fertilizer inputs were the highest consumer of energy in the production of canola in these three regions. the results indicated that despite the higher energy use of machinery in trakya province of t...

Pairwise orthogonal topological indices A and Woo derived from the characteristic graphs of alternant polycyclic aromatic hydrocarbons (kata-annellated and peri-condensed systems) correlate with resonance energy per electron, energy of the HOMO and total ;i: electron energy respectively. For topological indices a high discrimination power is necessary but not sufficient to correlate with molecu...

This paper presents a new composite index to analyze power system transient stability. Contingency ranking in power system transient stability is a complicated and time consuming task. To prevail over this difficulty, various indices are used. These indices are based on the concept of coherency, transient energy conversion between kinetic and potential energy and three dot products of the s...

in this paper, non parametric data envelopment analysis (dea) was subjected to the energy data of wheat producers in punjab state, india, and technical, pure technical and scale efficiencies were calculated for farms both category wise and zone wise. the main objective was to determine the strength of the correlation between non-parametric efficiencies and indices such as energy ratio and speci...
