In this paper, we focus on two issues. First, we analyze the potential biases in reported hedge fund returns, in particular survivorship bias and backfill bias, and attempt to create an unbiased return sample. Second, we decompose these returns into their three A,B,C components: the value added...

We present an account of the background, principles and requirements for the classification of Chinese coals. A great deal of experimental work has been carried out on a wide variety of rich coal resources in China. Studies have been conducted on classification parameters for coals with low,...

Optimal sections have been applied to the classification of bituminous coals according to the magnitudes of the parameters Vr and (G)R.I., which reflect metamorphism and caking properties of coal, respectively. The points at which the sections are divided and the number of groups are determined...

This paper addresses the sampling period scheduling of Networked Control Systems (NCSs) with multiple control loops. The generalized exponential function is employed to describe Integral Absolute Error (IAE) performance versus sampling period by Truetime toolbox under Matlab environment, and the...

To help a firm reduce inefficiencies associated with equipment capacity planning, we propose a <i>dual-mode equipment procurement</i> (DMEP) framework. DMEP combines dual-source (i.e., a less-expensive-but-slower base mode and a faster-but-more-expensive flexible mode) procurement with option contracts...
