Cluster validity indexes have been used to evaluate the fitness of partitions produced by clustering algorithms. This paper presents a new validity index for fuzzy clustering called a partition coefficient and exponential separation (PCAES) index. It uses the factors from a normalized partition coefficient and an exponential separation measure for each cluster and then pools these two factors t...

The indexes of multifactor productivity for two-digit manufacturing sectors prepared by the Bureau of Labor Statistics for sectors in manufacturing have been revised and extended to cover the 1949–92 period. These indexes, also called the “KLEMS” multifactor measures, compare changes in output to changes in a composite of all the inputs used in production—capital, labor, energy inputs, nonenerg...

We propose a novel set of indexes to classify the information content of Persistent Scatterers (PS) and rate the health of engineering structures at urban to local scale. PS are automatically sampled and grouped via ‘control areas’ coinciding with the building and its surrounding environment. Density over the ‘control areas’ and velocity of PS are converted respectively into: Completeness of In...

Many large-scale key-value storage systems sacrifice features like secondary indexing and/or consistency in favor of scalability or performance. This limits the ease and efficiency of application development on such systems. Implementing secondary indexing in a large-scale memory based system is challenging because the goals for low latency, high scalability, consistency and high availability o...

OBJECTIVE This work intends to evaluate the functional characteristics of the cerebral network during the successful memory encoding of TV commercials. METHODS We estimated the functional networks in the frequency domain from a set of high-resolution EEG data in a group of healthy subjects during the showing of commercial spots within a neutral documentary. We evaluated the differences in the...

Efficiently storing and searching collections of similar strings, such as large populations of genomes or long change histories of documents from Wikis, is a timely and challenging problem. Several recent proposals could drastically reduce space requirements by exploiting the similarity between strings in so-called referencebased compression. However, these indexes are usually not searchable an...

Energy efficiency is more and important for modern electrified transportation systems, requiring an understanding of the various indexes performance (regenerability, receptivity, energy losses, thus including braking recovered loss in catenary) influence main system parameters (headway, line voltage, substation separation, etc.). By means electromechanical simulation, most relevant conditions a...

The purpose of this paper is to analyze the overall equipment efficiency (OEE) of the machines in the production process, with the objective of measure the quality and efficiency of the process and the used resources (machines). For this analysis the present work shows the Colored Petri Nets for the modeling the flow data in Factory Information System (FIS). The obtained net represents the nece...
