extended abstract introduction hospitals are the most important and complex social units which are intended to protect the lives of people and to treat and improve them. with the passage of time and progress in science, hospitals have been equipped with more advanced technology and facilities. more active beds in hospitals are indications of specialized manpower, equipment and facilities for th...

In this paper, we find the relationship between mincut circuit partitioning and the initial (V, E) pairs distributed condition I entropy on the V-E plain. If a circuit has higher initial potential / entropy, under a nearly max-cut reservation, we have higher probability to aim the mincut. The proposed new method is called Interleaved Cutting Edge-Node Interleaved Sort for Leaching and Envelop (...

This article provides a look at business concentration for sales and assets for the period 1967 to 2002 based on Theil’s entropy, a measure adopted by several authors in earlier publications. For contrast, three other well-known measures of concentration, the HirschmanHerfindahl (HHI) index and the 4-firm and 8-firm concentration ratios, CR4 and CR8, were utilized. Data used were sales and asse...

The aim of this paper is to present an axiomatization of a generalization of Shannon’s entropy starting from partitions of finite sets. The proposed axiomatization yields as special cases the Havrda-Charvat entropy, and thus, provides axiomatizations for the Shannon entropy, the Gini index, and for other types of entropy used in classification and data mining. Keywords—Shannon entropy, Gini ind...

In this paper, at first we derive a family of maximum Tsallis entropy distributions under optional side conditions on the mean income and the Gini index. Furthermore, corresponding with these distributions a family of Lorenz curves compatible with the optional side conditions is generated. Meanwhile, we show that our results reduce to Shannon entropy as $beta$ tends to one. Finally, by using ac...

Malmquist Productivity Index (MPI) is one of the most famous indices, which is used for estimating the productivity change of a Decision Making Unit (DMU) during the time. Virtually any empirical study that uses MPI, reports average of the productivity indices they estimate to represent the overall tendency in productivity changes. In such a case, productivity indices of a DMU are considered wi...

We propose a new entropy-based algorithm for static index pruning. The algorithm computes an importance score for each document in the collection based on the entropy of each term. A threshold is set according to the desired level of pruning and all postings associated with documents that score below this threshold are removed from the index, i.e. documents are removed from the collection. We c...
