as known, repetition sometimes is considered improper in regular books. in spite of the fact that the holy quran is a miraculous book and repetition is not occurred in it without transcendental reasons, why there is so many repetitive verses in qur'an? assuming lack of spiritual repetition and that the only model of repetition in the quran is verbal repetition and the repetition is conside...

Previous studies have shown that letter repetitions are detected more rapidly when presented bilaterally (one letter in each visual field) than when presented unilaterally (both in the same field) when subjects have to report matches independently of case or font (e.g., Aa). This pattern of results is referred to as a bilateral field advantage. Here, we present evidence of an opposite pattern o...

When stimuli are presented rapidly, repetitions are often undetected--a phenomenon called "repetition blindness" (RB; Kanwisher Cognition, 27, 117-143, 1987). Grouping of nonlinguistic items has been found to prevent RB (Goldfarb & Treisman Psychonomic Bulletin & Review, 18, 1042-1049, 2011). In order to determine whether this effect could be found with letters and words, participants viewed ra...

Recently, Kitaev [9] introduced partially ordered generalized patterns (POGPs) in the symmetric group, which further generalize the generalized permutation patterns introduced by Babson and Steingrı́msson [1]. A POGP p is a GP some of whose letters are incomparable. In this paper, we study the generating functions (g.f.) for the number of k-ary words avoiding some POGPs. We give analogues, exten...

A repetition in a string of letters consists of exact concatenations of identical factors of the string. Crochemore’s repetitions algorithm, usually also referred to as Crochemore’s partitioning algorithm, was introduced in 1981, and was the first optimal O(n log n)-time algorithm to compute all repetitions in a string of length n. A weighted string is a string in which a set of letters may occ...

In this work, we analyze the potential efficiency of a low-loss, tunable secondand third-order dispersion compensating module based on a stretched optical fiber for ultra high-speed telecommunication systems. Experimental results at a repetition rate of 640 GHz show that precise dispersion compensation could be achieved in the range of +/0.038ps/nm by means of an 11.3cm maximum stretching of a ...

Repetition blindness (RB) is the failure to detect or recall repetitions of words in rapid serial visual presentation. Experiment 1 showed that synonym pairs are not susceptible to RB. In Experiments 2 and 3, RB was still found when one occurrence of the word was part of a compound noun phrase. In Experiment 4, homonyms produced RB if they were spelled identically (even if pronounced differentl...

the careful selection and proper use of lexical elements is the distinguishing feature of the holy quran. these elements are classified as subsets of semiotics and each of them play their role within the context of a surah and topics that it covers. for example in luqman surah topics such as monotheism, polytheism, atheism, prayer and the day of resurrection are discussed by different methods s...
