language is a system and every system has rules that govern the structure of its vocabulary. the rules of the arabic language are based on the vowels that consistent with the meanings used in the context represent the words' position. there are some basic rules in addition to vowels which are mostly seen in the written texts. one of these rules is the matching rule that refers to the condi...

background: one of the challenges of pet/mri combined systems is to derive an attenuation map to correct the pet image. for that, the pseudo-ct image could be used to correct the attenuation. until now, most existing scientific researches construct this pseudo-ct image using the registration techniques. however, these techniques suffer from the local minima of the non-rigid deformation energy f...

Abstract One key hypothesis explaining the fate of exotic species introductions posits that establishment a self-sustaining population in invaded range can only succeed within conditions matching native climatic niche. Yet, this remains untested for individual release events. Using dataset 979 173 mammal worldwide, we show climate-matching to realized niche, measured by new Niche Margin Index (...

the purpose of the matching interdiction problem in a weighted graph is to findtwo vertices such that the weight of the maximum matching in the graph withoutthese vertices is minimized. an approximate solution for this problem has beenpresented. in this paper, we consider dendrimers as graphs such that the weightsof edges are the bond lengths. we obtain the maximum matching in some types ofdend...

This paper tests the effect of matching charitable giving in a randomized field experiment. The students at the University of Zurich have to decide, each semester, whether they wish to contribute to two social funds. The donations of the treatment group are matched by contributions of an anonymous donor. The results support the hypothesis that a matching mechanism increases contributions to a p...

This paper tests whether aggregate matching is consistent with random matching or stock-flow matching. Using U.K. matching data and correcting for temporal aggregation bias, estimates of the random matching function are consistent with previous work in this field. The data however support the ‘stock-flow’ matching hypothesis. Estimates find that around 50% of newly unemployed workers match quic...

This paper describes link discovery technology that is designed to detect threat activities by extracting and piecing together transactional evidence from massive datasets that are composed mostly of noise and clutter. The approach is an integration of several innovative component technologies, including partial pattern matching, hypothesis evaluation and hypothesis merging.

Schema matching is a critical step in many applications, such as data warehouse loading, Online Analytical Process (OLAP), Data mining, semantic web [2] and schema integration. This task is defined for finding the semantic correspondences between elements of two schemas. Recently, schema matching has found considerable interest in both research and practice. In this paper, we present a new impr...
