The adoption by Medicare in 1983 of prospective payment using diagnosis-related groups (DRGs) has stimulated research to develop case-mix grouping schemes that more accurately predict resource consumption by patients. In this article, the authors explore a new method designed to improve case-mix classification for newborns through the use of birth weight in combination with DRGs to adjust the u...

OBJECTIVES It is difficult to draw conclusions about the prudence of antibiotic use in different hospitals by directly comparing usage figures. We present a patient case-mix adjustment model of antibiotic use to rank hospitals while taking patient characteristics into account. PATIENTS AND METHODS Data on antibiotic use were collected during the national healthcare-associated infection (HAI) ...

Silica fume has been largely used in concrete in recent decades due to its effect on improvement of strength and &#10durability of concrete. On the other hand, attention has been recently paid to the use of limestone powder as a substitute for part of cement in concrete, basically because of its low price and its positive effect on the durability of concrete. The aim of the current study is the...

Cementitious composites are one of the most consumed construction materials in the world. The use of cementitious composites is increasing due to their special characteristics. The behavior of high strength cementitious composites is improved by increasing the fiber percentage. In the present paper, the effects of steel microfibers and polypropylene fibers on mechanical properties and impact re...

In a mix-net, information regarding the network health and operational behavior of the individual nodes must be made available to the client applications so they may select reliable nodes to use in each message’s path through the mix-net. We introduce the concept of a pinger, an agent which tests the reliability of individual mixes in the mix-net, and publishes results for the mix clients to ev...

In our work we use queuing theory both for security (i.e. anonymity) and performance analysis. A well-known anonymity technique, the MIX method, which is the basis of most of today’s deployments, is the object of our investigation. We show shortcomings and problems in the MIX method and suggest possible workarounds. Our investigation reveals the level of security of MIX based systems and their ...
