one-way analysis of covariance is a popular and common statisticalmethod, wherein the equality of the means of several random variables whichhave a linear relationship with a random mathematical variable, is tested. inthis study, a method is presented to improve the one-way analysis of covari-ance when there is an uncertainty in accepting the statistical hypotheses. themethod deals with a fuzzy...

pain is a phenomenon experienced more or less by all people during their lives. since sufferers usually use language as the most important human communication tool to inform others about their pains, sentences describing pain and studying them linguistically may reveal some points. in this paper, after a short introduction to the subject and reviewing the literature, we take one of the systemat...

feature geometry, which is a basic assumption in current phonology, is concerned with the notion that the features are not an unstructured set, but are arranged hierarchically into a constituent structure tree. according to evidences in different languages, various models have been set forth on feature geometry framework. exploring persian phonological data and digging up evidences accordingly,...

background and objectives: active presence of hospitals on the internet is becoming a hallmark of hospitals’ commitment to quality healthcare services delivery. for insightful planning towards a strong internet-based information delivery and communication, there is a need for continuous monitoring of hospital website’s status. built on this need, this paper provides, for the first time, a ranki...

web search engines are one of the most popular tools on the internet which are widely-used by expert and novice users. constructing an adequate query which represents the best specification of users’ information need to the search engine is an important concern of web users. query expansion is a way to reduce this concern and increase user satisfaction. in this paper, a new method of query expa...

In this paper, we present an ongoing work aiming to improve content based image retrieval performance with the help of logical concept analysis. Domain semantic is formalized and used instead of classical CBIR visual features. This is being applied to comicbooks using Sewelis.

Pairing heaps were introduced as a self-adjusting alternative to Fibonacci heaps. They provably enjoy log n amortized costs for the standard heap operations. Although it has not been veri ed that pairing heaps perform the decrease key operation in constant amortized time, this has been conjectured and extensive experimental evidence supports this conjecture. Moreover, pairing heaps have been ob...

The number of knowledge-based systems that build on Bayesian belief networks is increasing. The construction of such a network however requires a large number of probabilities in numerical form. This is often considered a major obstacle, one of the reasons being that experts are reluctant to provide numerical probabilities. The use of verbal probability expressions as an additional method of el...

It is of great biological interest to understand the molecular origins of chemotactic behavior of E. coli by developing population-level models based on the underlying signaling pathway dynamics. We derive macroscopic models for E.coli chemotaxis that match quantitatively with the agent-based model (SPECS) for all ranges of the spacial gradient, in particular when the chemical gradient is large...
