In practical applications of pattern recognition, there are often different features extracted from raw data which needs recognizing. Methods of combining multiple classifiers with different features are viewed as a general problem in various application areas of pattern recognition. In this paper, a systematic investigation has been made and possible solutions are classified into three framewo...

Development Progress is an ODI project that aims to measure, understand and communicate where and how progress has been made in development. ODI is the UK's leading independent think tank on international development and humanitarian issues. Further ODI materials are available at odi.org.uk • Neglected tropical diseases (NTDs) have a direct impact on the achievement of the Millennium Developmen...

This report proposes a standard method to characterize variability and sensitivity of functional neuroimaging experiments. Most functional neuroimaging analyses result in statistic images of signal-to-noise. However, it is essential to examine both signal and noise individually, to characterize sensitivity and to identify artifacts. Confidence intervals simultaneous convey signal and noise but ...

A distributed suction i1igh-lift boundary layer control system fitted to a standard liaison L-19 aircraft incre~sed the aircraft c 1 max to 5.74 and decreased the take-off and landing distance over a 50-foot obstacle by 38 percent and 29 percent, respectively, with no increase in available power. The modified aircraft demonstrated acceptable stability, control, and handling characteristics in a...

The difference between the disease rates of two groups, one exposed and one not exposed to a suspected aetiological factor, is a useful measure of the risk associated with the factor. This measure is of most interest when the association is considered causal, and has been termed the attributable risk (MacMahon and Pugh, 1970). Expressed as a percentage of the total disease rate in a group (the ...

A "thrifty gene" may put some groups at risk for type 2 diabetes. More than 20.8 million Americans—7 percent of the population—have diabetes. The number continues to grow, driven mostly by an upsurge in obesity. From 1994 to 2004, diagnosed diabetes rose at least 50 percent in 23 states. In addition, an estimated 54 million U.S. adults have prediabetes—an elevated blood sugar level that is not ...

Insurers and policymakers encourage the use of generic drugs to reduce costs, but generics remain underused. We conducted a national survey of commercially insured adults to evaluate their perceptions about generic drugs. Patients agreed that generics are less expensive and a better value than brand-name drugs, and are just as safe. However, although 56 percent reported that Americans should us...
