A controversial area in covariance structure models is the assessment of overall model fit. Researchers have expressed concern over the influence of sample size on measures of fit. Many contradictory claims have been made regarding which fit statistics are affected by N. Part of the confusion is due to there being two types of sample size effects that are confounded. The first is whether N dire...

Abstract For low voltage ride through (LVRT) of the wind power generation system, rotor energy storage and super capacitor are promising options. When cooperates with for LVRT, DC will undulate violently due to speed fluctuation. To solve this problem, a crowbar circuit topology its control strategy including unloading resistance proposed in paper. During process resistor absorb energies togeth...

in order to study the effects of ascorbic acid as an important antioxidant reducing salinity damage, an experiment was conducted on two althernantera genotypes (“entire leaf” and “undulated leaf”) at research greenhouse of shahid chamran university in 2013. concentrations of 0, 0.5 and 1 mm of ascorbic acid were sprayed weekly on plants grown under 0, 30, 60, 90 mm nacl. the experiment was carr...

A long running challenge in both large and small organizations has been aligning information systems services with business needs. Good alignment is assumed to lead to good business results, but there is a need for good instruments to assess strategic alignment and business success in practice. Based on existing information management theories, we develop the I-Fit model and the I-Fit tool. The...
