Based on Supper Efficiency DEA model, and applying Stochastic Frontier Approach(SFA)to eliminate the influence from environment and random error factors, this paper researches carbon emission efficiency of China's 30 provinces(cities, districts)from 1997 to 2011 in phases. The results show that the...

Although several techniques have been put forward for the computation of energy efficiency, it is clear from the existing scholarship that two techniques—the stochastic frontier approach (SFA) and the data envelopment analysis (DEA) have been widely used. In this study, however, we relied on the...
In reference [22], Dai introduces both the ratio of actual Euclidean distance to accumulated hop distance and the hops between anchor nodes to design a correction coefficient. However, it still uses the correction model based on anchor nodes, that is, each unknown node receives the corresponding...

The examples of measured DC transfer characteristics between input voltage (VY) and output current (IZ), are shown in Figure 3a; VX serves as the DC constant, driving overall transconductance (in accordance to gm ∼= 1.3 × 10−3 VX). The gain bandwidth (GBW) of the real prototype ...
The objective of this work was to evaluate the normalized difference water index (NDWI) based on Sentinel-2 imagery as a tool for monitoring pasture seasonal dynamics and inter-annual variability in a Mediterranean agro-silvo-pastoral system. Forty-one valid NDWI records were used between January ...
