Combining an EWMA chart with a Shewhart chart is traditionally recommended as a means of providing good protection against both small and large shifts in the process mean. Capizzi and Masarotto have proposed an EWMA chart with a variable smoothing constant (AEWMA) for the same purpose. In this paper, we optimize the designs of the AEWMA and of the combined EWMA-Shewhart schemes with regard to p...

Online social platforms collapse or converge public and private boundaries, creating both opportunities and challenges for pursuing publicity, privacy, and sociality. Presentations of the self thus become networked performances that must convey polysemic content to audiences, actual and imagined, without compromising one’s own sense of self. This study explored how individuals perform the self ...

We present an overview of current research in performance modeling, focusing on efforts underway in the Performance Evaluation Research Center (PERC). Using some new techniques, we are able to construct performance models that can be used to project the sustained performance of large-scale scientific programs on different systems, over a range of job and system sizes. Such models can be used by...

Solving many actual safety problems in atomic, electrotechnical, space, railway and oil industries as well as in science takes noncontact optical measurement technologies with micron resolution and productivity from 500 to 100 000 meas./s. We have developed, implemented and tested in real workshop and outside conditions some novel optical measuring systems, which are operating successfully in m...

This article describes the need of using Protocol Engineering techniques to study current telecontrol protocols and this way improve their performances by setting them up or changing for others, such as standardised ones (testing their implementations).

Previous studies have shown that after being trained on A-B and A-C match-to-sample tasks, adults match not only same-class Band C stimuli (equivalence) but also BC compounds with sameclass elements and with different-class elements (BC-BC) . The assumption was that the BC-BC performances are based on matching equivalence and nonequivalence relations (equivalenceequivalence) . The present study...

This research has objective to develop a model of key performance indicators (KPI) measurement in higher education institution. The proposed model is based on combination between AHP, trend analysis and comparative data.. KPIs are determined as description of key success factors related to institution sustainability. These KPIs are chategorized into academic, research and supporting KPI. Each K...

A new and simple greenhouse crop transpiration model enabling predictions from outdoor conditions is presented and the parameters involved are discussed with respect to different types of greenhouse-crop systems. This transpiration model was validated against experimental data measured in a soil-less tomato crop cultivation in Avignon in summer conditions, when the greenhouse is open, and early...

1. The paper presents brief descriptions of various cell suppression software packages, focussing on availability, costs, platforms, and the underlying methodology. The systems performances will be compared with respect to information loss, and computing time requirement; other key qualities of the software will be discussed.

The X-ray satellite BeppoSAX 1 , a major programme of the Italian space agency with participation of the Dutch space agency, was successfully launched from Cape Canaveral on April 30, 1996. After a 2 months period devoted to engineering check out that confirmed the nominal functionality of the satellite and the scientific payload, we have performed a series of observations of celestial objects ...
