Rainwater collected from residential roofs and greywater generated from domestic uses except toilets are viewed as possible substitutes for high grade water sources which supply nonpotable indoor uses and irrigation in Australia. This paper searches for alternatives by adopting roofwater and...

Time invariance of factor loadings is a standard assumption in the analysis of large factor models.  Yet, this assumption may be restrictive unless parameter shifts are mild (i.e., local to zero).  In this paper we develop a new testing procedure to detect big breaks in these loadings at...

Coal-fired gasifiers are the key technology for clean power generation and coal chemical process. This paper presents a 2-stage entrained flow dry powder gasifier in which coal is entrained into the lower chamber burner with oxygen and steam to raise the temperature of the crude gas up to...

We demonstrate a simple high-throughput single-cell approach that exploits the ultrahigh brightness and non-invasive nature of synchrotron infrared beam to characterize strains of the cyanobacterium Synechocystis 6803 (S. 6803) constructed with altered metabolic traits affecting the acyl-CoA...

Despite their popularities in recent years, factor models have long been criticized for the lack of identification. Even when a large number of variables are available, the factors can only be consistently estimated up to a rotation. In this paper, we try to identify the underlying factors by...

Based on the logarithmic mean Divisia index (LMDI) approach, this paper presents a decomposition analysis of China’s energy-related industrial CO<sub>2</sub> emissions from 1985 to 2007, as well as a comparative analysis of differential influences of various factors on six sectors. Via the decomposition,...

A Cournot duopoly, with a bounded inverse demand function and different constant marginal production costs, can be modeled as a discrete-time dynamical system, which exhibits complex bifurcating and chaotic behaviors. Based on some essential features of the model, we show how bifurcation and...

The proposed work develops a method for classification of the species of a fish given in an image, which is a sub-ordinate level classification problem. Fish image categorization is unique and challenging as the images of same fish species can show significant differences in the fish's...
