data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

the present study used different categories of organized sector manufacturing industries pooled data for the periods of 1981-82 and 2007-08 in haryana state (india). the present undertaking seeks to analyze the inter-temporal and inter-industry comparison of total factor productivity (tfp) measured by malmquist productivity index - an application of dea which calculates the indices of tfp and i...

The aim of this paper is to analyze total factor productivity (TFP) growth and its components in Asian countries applying Stochastic Frontier Analysis (SFA) to the time series data of 44 Asian countries from 2000 to 2010. Using Battese and Coelli approach, TFP is divided into technical efficiency change and technical change. TFP decomposition using SFA method for the years 1998 to 2007 indicate...

A Point-Over-Threshold approach using a reparameterization of the Generalized Pareto Distribution (GPD) has been used to assess changes in the daily rainfall Barcelona series (1854–2006). A Bayesian approach, considering the suitable scale and physical features of the phenomenon, has been used to look for these alterations. Two different models have been assessed: existence of abrupt changes in...

Precipitation efficiency (PE) relates cloud condensation to precipitation and intrinsically binds atmospheric circulation the hydrological cycle. Due PE’s inherent microphysical dependencies, definitions estimates vary immensely. Consequently, sensitivity greenhouse warming implications for climate change are poorly understood. Here, we quantify role in by defining a simple index ϵ as ratio of ...
