Methods of fuzzy rule extraction based on rough set theory are rarely reported in incomplete intervalvalued fuzzy information systems. This paper deals with such systems. Instead of obtaining rules by attribute reduction, which may have a negative effect on inducting good rules, the objective of this paper is to extract rules without computing attribute reducts. The data completeness of missing...
this thesis attempts to investigate the effects of prelistening activities on enhancing iranian efl learners` listening comprehension. the present study investigated ways in which learners` background knowledge could be activated in order to enhance their l2 listening comprehension by limiting the number of possible text interpretations prior to listening. the experiments conducted in this stud...
we show that when both sources ( lepton flavor violation sources and cp-violating phases) are present, the electric dipole moment of the electron, $d_e$, receives a contribution from the phase of the trilinear $a$-term of staus, $phi_{a_ au}$. for $phi_{a_ au}=pi/2$, the value of $d_e$, depending on the ratios of the lfv mass elements, can range between zero and three orders of magnitude a...
Various novel techniques including ultrasound-assisted extraction, microwave-assisted extraction and supercritical fluid extraction have been developed for the extraction of medicinal plants in order to shorten the extraction time, decrease the solvent consumption, increase the extraction yield, and enhance the quality of extracts. This review was conducted to introduce and compare the conventi...

Some non-coding small RNAs, known as microRNAs (miRNAs), have been shown to play important roles in gene regulation and various biological processes. The abnormal expression of some specific miRNA genes often results in the development of cancer. In this paper, we find discriminatory miRNA patterns for cancer classification from miRNA expression profiles with an information theory approach. Our...
As a rapidly booming industry in recent years, the key problem for Search Engine Marketing (SEM) is to extract web page attributes contributed to the ranking in search engine such as Google and Baidu. The quantitative analysis of these agricultural page attributes is aimed in this paper and the attribute extractor in Java platform is built. Meantime, in order to gain a sample set, a batch gaini...
the application of e-learning systems - as one of the solutions to the issue of anywhere and anytime learning – is increasingly spreading in the area of education. content management - one of the most important parts of any e-learning system- is in the concern of tutors and teachers through which they can obtain means and paths to achieve the goals of the course and learning objectives. e-learn...
Currently, the majority of Manifold Learning algorithms applied for SAR image feature extraction are vector based; the For tensor based SAR images, a “convert to vector: process has to be taken before attribute extraction. During this process, curse of dimensionality would be occurred and information of space geometry structure could be lost. Those phenomenon are not conducive for target recogn...
