Mining interesting itemsets is a popular topic in the data mining community. The objective of this problem is to mine all interesting itemsets, with respect to a given interestingness measure. While considerable efforts have being spent on justifying the various interestingness measures, the algorithms that mine them are not quite well-studied, except in the case support, which has resulted in ...

Let V and W be two real vector spaces and let &sim be a relation on both V and W. A linear function T : V → W is said to be a linear preserver (respectively strong linear preserver) of &sim if Tx &sim Ty whenever x &sim y (respectively Tx &sim Ty if and only if x &sim y). In this paper we characterize all linear functions T : M_{n,m} → M_{n,k} which preserve or strongly preserve multivariate an...

$!!!!$ in this paper, the notion of fuzzy $!$ krasner $!(m, n)$-hyperrings($!f^{(m, n)}!$-hyperrings) by using the notion of$f^m$-hyperoperations and $f^n$-operations is introduced and somerelated properties are investigated. in this regards,relationships between krasner $f^{(m, n)}$-hyperrings and krasner$(m, n)$-hyperrings are considered. we shall prove that everykrasner $f^{(m, n)}$-hyperrin...

In this paper we address the problem of how to extend the deenition of functional dependencies (FDs) in incomplete relations to XML documents. An incomplete relation is said to strongly satisfy a FD if every completion of the relation, obtained by replacing all null values by data values, satisses the FD in the ordinary sense. We propose a syntactic deenition of strong FD satisfaction in a XML ...

The observation of strongly lensed Type Ia supernovae enables both the luminosity and angular diameter distance to a source be measured simultaneously using single observation. This feature can used measure duality parameter $\eta(z)$ without relying on multiple datasets cosmological assumptions reconstruct relation between distances. In this paper, we show how achieved by future observations s...

Abstract The cosmic distance relation (DDR) associates the angular diameters ( ) and luminosity D_L by a simple formula, i.e., = (1+z)^2D_A . strongly lensed gravitational waves (GWs) provide unique way to measure simultaneously GW source, hence they can be used as probes test DDR. In this study, we investigated use of events from future Einstein Telescope We assumed possible ...

In this paper we are using intuitionistic fuzzy approach to minimize search domain in an accidental case where the data collected for investigation is intuitionistic fuzzy in nature. To handle these types of imprecise information we use intuitionistic fuzzy tolerance relation and translate intuitionistic fuzzy query to reach to the conclusion. Here we present an example of vehicle hit and run c...

Web Usage Mining is the application of data mining techniques to learn usage patterns from Web server log file in order to understand and better serve the requirements of web based applications. Web Usage Mining includes three most important steps namely Data Preprocessing, Pattern discovery and Analysis of the discovered patterns. One of the most important tasks in Web usage mining is to find ...
