This paper presents a comparative analysis of the productive efficiency of two types of firms in China --foreign-invested enterprises (FIEs) and state-owned enterprises (SOEs), using a stochastic frontier production function model and the latest statistical data (1993-97). It has found that the FIEs in general outperformed SOEs in productive efficiency, as demonstrated by the differentials in t...

An important task in computational statistics and machine learning is to approximate a posterior distribution p(x) with an empirical measure supported on a set of representative points {xi}i=1. This paper focuses on methods where the selection of points is essentially deterministic, with an emphasis on achieving accurate approximation when n is small. To this end, we present Stein Points. The i...

In the context of climate change in right-bank Forest-Steppe Ukraine, as well temperature fluctuations over years, an important direction increasing productivity arable land is cultivation drought-resistant leguminous crops and improvement technological methods aimed at creating highly productive agrocenoses. It has been studied that chickpeas are among crops, which can withstand high temperatu...

Heat recuperation is often used to improve the overall cycle efficiency of gas turbines. However, generally in small- scale gas turbines, it has a negative effect on turbine inlet temperature, pressure ratio and pressure drops, and thus decreases the overall cycle efficiency. In this paper, a thermodynamic model is performed to evaluate recovered heat as a function of heat exchanger effecti...
