Feedforward control is a particular form of engineering process control. If a known input variable zt can be measured and appropriate relationships built between the input variable, a compensatory variable xt, and the desired output yt, then a feedfo

Monitoring of particle contamination by statistically based methods is used extensively in semiconductor manufacturing. Often Shewhart-type control charts are used for this purpose. These charts suffer from some potential disadvantages in this applic

Trade-off analysis after optimization of an economic CUSUM control chart is proposed. This procedure exploits the relatively flat response surface in the neighborhood of the optimal design. Comments are made with respect to criticisms of pure economi

The Cumulative Sum Chart for process control is designed to detect relatively small shifts in the mean of the process variable. In this paper, we show that by using samples of two different sizes, rather than a fixed sample, improvements in the chart

The Friedreich's ataxia locus (FRDA) is tightly linked to markers D9S5 and D9S15 located in 9q13-q21. Cumulated maximum lod scores between FRDA and D9S5 and between FRDA and D9S15 are above 36 and 61, respectively, at a recombination fraction of 0, i

Standard Shewhart control charts employ fixed sample sizes at equal sampling intervals. By varying the sample size depending on the current location of the process mean, the mean time to detect an off-target condition can be reduced. The adaptive-sam

The control of water-resources systems can be extremely complicated because of the difficulty in accurately modeling such systems. Many systems are controlled manually by operators with subjective, ad hoc rules. Other system controls are based on sta

Bayesian inference is applied to the real-time feedback control of a basin irrigation system. Estimates of the Kostiakov \Ik\N (infiltration parameter) and Manning \In\N (Roughness parameter) are obtained during water advance so that the optimum cuto

Population-based association studies have supported the heritability of posttraumatic stress disorder (PTSD). This study explored the influence of genetic variation in the dopamine transporter (DAT) 3' untranslated region variable number tandem repea

Mouse models for human deafness have not only proven instrumental in the identification of genes for hereditary hearing loss, but are excellent model systems in which to examine gene function as well as the resulting pathophysiology. One mouse model
