Many industrial processes need steam at temperatures from 100 to 200 °C, normally produced by directly heating water via coal, natural gas or oil combustion. Nevertheless, large amounts of unused heat below 100 °C are wasted in other industrial processes. In principle, a high-temperature...

The paper discusses the development of the third mission of Chinese universities. The main approaches and challenges of two universities, Tsinghua University and Beihang University, are examined to elucidate the third mission of Chinese research universities in a knowledge-based economy. The...

A conditional test based on a Hotelling'sT2-type statistic is derived for significance of a multivariate mean having non-negative components. This test is shown to be uniformly more powerful than the unconditional test given by Silvapulle. The consistency and invariance of the new test are also...

This note shows a major problem in the proof of Anscombe's conjecture given in Aragon et al. (1992). It also proves that the unbiased estimator of the parameter k does not exist.

This note gives a simple condition for the nonexistence of nontrivial ancillary statistics. The result shows that in sampling from a discrete exponential family with a regression model, usually there is no nontrivial ancillary statistic.

The purpose of extension is to disseminate advice to farmers. Knowledge gaps contribute to yield gaps. Services and quality inputs are essential productivity-enhancing tools. However, their optimum use requires knowledge. Farmers also need information on prices and markets, post-harvest...

Retailers have an incentive to cooperate in the form of group buying (GB) when a supplier provides quantity discounts, because wholesale price under GB depends on total purchasing quantity rather than individual purchasing (IP) quantity. Most previous studies on GB focus on the benefits that...
