A bstract Understanding diagrams is an important part of human cognition. Computer programs need to understand and reason using diagrams to communicate effectively with people. This paper explains how line graphs can be interpreted in a domain independent manner. We present a computer program called SKETCHY that reasons about physical phenomena visually by using line graphs. SKETCHY can interpr...

individual Plg-Rs to monocyte recruitment may change over time (enolase-1 early vs H2B later). These suggestions imply that different populations of Plg-Rs could be targeted to regulate inflammatory cell recruitment in a temporal or site-specific manner. The resurrection of enolase-1 as a Plg-R by the Wygrecka et al provides impetus for such comparative studies. Conflict-of-interest disclosure:...

Comparative studies of British-American ballad tunes have in most cases been based on transcriptions of a single stanza of each ballad analyzed. Folk singers rarely sing any two stanzas of a ballad in exactly the same manner. Nor i s a second rendition of a ballad likely to be an exact reproduction of the f i rs t rendition. Thus it cannot be expected that the application of this method will pr...

The purpose of this paper is to provide hospital managers with important knowledge and skills in developing efficiency measures that hospital can use as guidelines in monitoring and controlling operational costs. Efficiency measures are judgmental and comparative. Cost and quantity are the variables in the computation of efficiency measures but it is very important to integrate these variables ...

In this paper a new variant of HMM named distributed VQ HMM (DVQHMM) is presented. Its main characteristic is the use of a code books distributed on HMM states with a new manner of HMM parameters estimation. Procedures for training and HMM evaluation of each recognition unit are described. Comparative results on an isolated phoneme recognition system are shown, between DVQHMM and conventional V...

We consider the problem of clustering data streams. A data stream can roughly be thought of as a transient, continuously increasing sequence of time-stamped data. In order to maintain an up-to-date clustering structure, it is necessary to analyze the incoming data in an online manner, tolerating but a constant time delay. The purpose of this study is to analyze the working of popular algorithms...

Routing is a challenging issue in Mobile Ad hoc Network to pass the data packets through intermediate hops in an efficient manner. In this paper, Reactive routing protocols namely AODV and DSR are evaluated under the feasible placement and random placement models. Simulation results shows that AODV and DSR are performing better in feasible placement approach comparative to the existing random p...

This report aims to give a brief overview of the current state of document clustering research and present recent developments in a well-organized manner. Clustering algorithms are considered with two hypothetical scenarios in mind: online query clustering with tight efficiency constraints, and offline clustering with an emphasis on accuracy. A comparative analysis of the algorithms is performe...

Researchers have shown that many, though not all, of the basic results of expected utility analysis can be more or less directly generalized to non-expected utility preferences. This paper describes the essential difference between results which can be extended in this manner and those which cannot and shows that an important family of comparative statics theorems falls into the former class. J...
