Lead potassium niobate (Pb2KNb5015, PKN) single crystal with tungsten bronze has been successfully grown by Bridgman method through spontaneous nucleation. Under the optimized growth conditions, the crystal was transparent, cracks free and inclusions free. The mechanical property was measured through the Vickers microhardness technique. The result showed that the relationship between the Vickers'...
A popular technique to measure efficiency comprise of a two-stage approach, consisting Data Envelopment Analysis (DEA) with Tobit regression. Since the highest efficiency score of DEA is censored at one, this method has some weakness of covering additional information at the upper bound of the efficiency scores. This research adopts the super-efficiency model as an alternative of DEA-based approach...
In this study, two-stage data envelopment analysis (DEA) was applied to evaluate operational efficiency of 54 international tourist hotels in Taiwan in 2008. Hotel industry's operating activities are divided into two sub-processes, including profitability and marketability for analyzing the efficiency differences. Results from the efficiency value and management matrix provide information as a reference...
