Usually, in monitoring schemes the nominal value of the process parameter is assumed known. However, this assumption is violated owing to costly sampling and lack of data particularly in healthcare systems. On the other hand, applying a fixed control limit for the risk-adjusted Bernoulli chart causes to a variable in-control average run length performance for patient populations with dissimilar...

Amphiphilic ABC triblock copolymers composed of monomethoxy-capped poly(ethylene glycol) (MPEG), poly(2-(dimethylamino)ethyl methacrylate) (DMA), and poly(2-(diethylamino)ethyl methacrylate) (DEA) have been synthesized by atom transfer radical polymerization (ATRP). These copolymers dissolve molecularly in acidic aqueous media at room temperature due to protonation of the tertiary amine groups ...

Abstract The secondary goal approach is an effective way to address the problem of non-uniqueness optimal weights for decision-making units (DMUs) in cross-efficiency evaluation process data envelopment analysis (DEA). However, on one hand, existing secondary-goal models seldom consider willingness DMUs accept and be satisfied with results DEA. On other zero excessive differences indicators has...

D-eritadenine (DEA) is a potent inhibitor (IC(50) = 7 nm) of S-adenosyl-l-homocysteine hydrolase (AdoHcyase). Unlike cyclic sugar Ado analogue inhibitors, including mechanism-based inhibitors, DEA is an acyclic sugar Ado analogue, and the C2' and C3' have opposite chirality to those of the cyclic sugar Ado inhibitors. Crystal structures of DEA alone and in complex with AdoHcyase have been deter...

DEA models treat the DMU as a “black box.” Inputs enter and outputs exit, with no consideration of the intervening steps. Consequently, it is di(cult, if not impossible, to provide individual DMU managers with speci;c information regarding the sources of ine(ciency within their DMUs. We show how to use DEA to look inside the DMU, allowing greater insight as to the sources of organizational ine(...

In this study, the data envelopment analysis (DEA), three-stage DEA (3SDEA) and artificial neural network (ANN) are employed to measure the technical efficiency of 29 semi-conductor firms in Taiwan. Estimated results show that there are significant differences in efficiency scores among DEA, 3SDEA and ANN analysis. The advanced setting of the three stages mechanism of DEA does show some changes...

This research presents a new application of Data Envelopment Analysis (DEA) to empirically determine prices of multiple products. The DEA technique is now widely applied to performance analysis and efficiency measurement in economics, business and other areas in social science. This study does not explore such conventional DEA uses, rather directing towards a new DEA application to the determin...

ROBERT CAMPBELL, in honour of whose nmemory this lecture is held, was one of the great pioneers of aseptic surgery. He was the first surgeon to use rubber gloves in the British Isles, and he was responsible for many advances in our craft. He had a particular interest in the surgery of repair, and his appointment at the Children's Hospital gave him nmany opportunities to restore by means of repa...

As a dynamic, temporary alliance, virtual enterprise plays an important role for firms to face the global competition. Among many actions in the virtual enterprise running, virtual enterprise construction is the one which impacts virtual enterprise performance most direct and deeply, however, partner selection decision is the key of the virtual enterprise construction. This paper mainly helps t...
