Suppose that one has the freedom to adapt the observational network by choosing the times and locations of observations. Which choices would yield the best analysis of the atmospheric state or the best subsequent forecast? Here, this problem of ‘‘adaptive observations’’ is formulated as a problem in statistical design. The statistical framework provides a rigorous mathematical statement of the ...

Micro electro-mechanical systems (MEMS) and devices are taking an increasingly active role in products ranging from automotive airbag sensors to micromirrors used in projectors. Even with the increasing use of MEMS devices, they are still largely overshadowed by their VLSI cousins. MEMS designers typically use VLSI-tuned processes to develop and even produce MEMS devices. This practice leads to...

The aim of this article is to explore the use of statistical design in biomedical engineering applications. These techniques are not extensively used in this discipline possibly due to the current content of most curriculum. They may however be very valuable in optimizing the performance of biomedical devices and systems. We first review the two major methods of statistical design, namely the T...

incorporation of functional foods and nutraceuticals such as carotenoids which suffer from poor water solubility and low bioavailability into nano-sized delivery systems can improve their solubility, stability and oral bioavailability. the aim of this study was to prepare β-carotene nanodispersion and investigate the effects of preparation parameters by means of response surface methodology usi...

Acceptance control charts are effective tools tomonitor capable processes in which the fraction of the produced nonconforming items is very low. In these charts, some controlled changes in the process mean are allowed, and the production of a specified number of defectives is tolerated. Designing these acceptance control charts by considering the cost of sampling, detecting, and investigating o...

Introduction All of us in experimental science are concerned with scientific rigor and most journals have a policy on statistical analysis and data representation to ensure that issues of experimental design can be reviewed thoroughly. The policy at the Journal of Neuroscience is to require full reporting of statistical analyses and we ask our reviewers to report on the adequacy of those analys...

Chip multiprocessors (CMPs) combine increasingly many general-purpose processor cores on a single chip. These cores run several tasks with unpredictable communication needs, resulting in uncertain and often-changing traffic patterns. This unpredictability leads network-onchip (NoC) designers to plan for the worst-case traffic patterns, and significantly over-provision link capacities. In this p...

This paper reviews some of the work in the area of statistical circuit design. While space does not permit a more then superficial survey of the entire field, specific emphasis is placed on those techniques more familiar to the authors.

the multivariate exponentially weighted moving average (mewma) control chart is one of the best statistical control chart that are usually used to detect simultaneous small deviations on the mean of more than one cross-correlated quality characteristics. the economic design of mewma control charts involves solving a combinatorial optimization model that is composed of a nonlinear cost function ...

considerable investments have been made in establishing wastewater treatment plants (wwtps). however, evaluation of the performance of plants during recent years, when more wwtps have become operational, shows that effluent quality criteria were not met in many instances. preliminary assessment of the operational problems of wwtps in iran disclosed that numerous factors affect this issue of eff...
