Modified Fisher's Linear Discriminant Analysis for Hyperspectral Imagery

Abstract: In this letter, we present a modified Fisher's linear discriminant analysis (MFLDA) for dimension reduction in hyperspectral remote sensing imagery. The basic idea of the Fisher's linear discriminant analysis (FLDA) is to design an optimal transform, which can maximize the ratio of between-class to within-class scatter matrices so that the classes can be well separated in the low-dimensional space. The practical difficulty of applying FLDA to hyperspectral images includes the unavailability of enough training samples and unknown information for all the classes present. So the original FLDA is modified to avoid the requirements of training samples and complete class knowledge. The MFLDA requires the desired class signatures only. The classification result using the MFLDA-transformed data shows that the desired class information is well preserved and they can be easily separated in the low-dimensional space.

Indications that Live Poultry Markets Are a Major Source of Human H5N1 Influenza Virus Infection in China

Abstract: Human infections of H5N1 highly pathogenic avian influenza virus have continued to occur in China without corresponding outbreaks in poultry, and there is little conclusive evidence of the source of these infections Seeking to identify the source of the human infections, we sequenced 31 H5N1 viruses isolated from humans in China (2005 to 2010) We found a number of viral genotypes, not all of which have similar known avian virus counterparts Guided by patient questionnaire data, we also obtained environmental samples from live poultry markets and dwellings frequented by six individuals prior to disease onset (2008 and 2009) H5N1 viruses were isolated from 4 of the 6 live poultry markets sampled In each case, the genetic sequences of the environmental and corresponding human isolates were highly similar, demonstrating a link between human infection and live poultry markets Therefore, infection control measures in live poultry markets are likely to reduce human H5N1 infection in China

Combining preventive maintenance and statistical process control: a preliminary investigation

Abstract: The economic design of control charts and the optimization of preventive maintenance policies are two research areas that have recently received a great deal of attention in the quality and reliability literature. Both of these research areas are focused on reducing the costs associated with operating manufacturing processes. In addition, it is widely recognized that the maintenance of manufacturing equipment and the quality of manufactured product are related. However, these two research areas are rarely integrated. In this paper, a combined control chart–preventive maintenance strategy is defined for a process which shifts to an out-of-control condition due to a manufacturing equipment failure. An X¯ chart is used in conjunction with an age-replacement preventive maintenance policy to achieve a reduction in operating costs that is superior to the reduction achieved by using only the control chart or the preventive maintenance policy. This superior cost performance is demonstrated using a simulation-optimization approach.
