Image fusion is a method for obtaining a highly informative image by merging the relative information of an object obtained from two or more image sources of the same scene. The satellite cameras give a single band panchromatic (PAN) image with high spatial information and multispectral (MS) image with more spectral information. The problem exists today is either PAN or MS image is available fr...
toury (1978:200) believes that translation is a kind of activity which inevitably involves at least two languages and two cultural traditions. being polite while asking for something takes place differently in different cultures and languages, therefore various strategies may be applied for making requests and also translation of them in order not to disturb or threaten the face or better to sa...
hedging is a multi-purpose rhetorical strategy which is usually used in scientific arguments to secure ratification of claims, reduce the risk of negation, avoid conflict, manage disagreement and leave room for the audience to assess presented information. hedges are frequently used in research articles to mitigate the findings of research endeavors. the present research aims to investigate the...
In this paper, we review the spatial and spectral characteristics of blue and greennoise halftoning models. In the case of blue-noise, dispersed-dot dither patterns are constructed by isolating minority pixels as homogeneously as possible and by doing so, a pattern composed exclusively of high frequency spectral components is produced. Blue-noise halftoning is preferred for display devices that...
A "Qi" feeling (a kind of comfortable sense) during and after acupuncture is one of the important determinants to decide quantity (trial number) of acupuncture stimulation. It has been reported that various autonomic responses were evoked when patients felt "Qi" and when acupuncture stimulation had significant effects on EEGs. However, quantitative relationships among acupuncture stimulation, E...

This paper proposes a novel framework that enables us to manipulate and control formants in HMM-based speech synthesis. In this framework, the dependency between formants and spectral features is modelled by piecewise linear transforms; formant parameters are effectively mapped by these to the means of Gaussian distributions over the spectral synthesis parameters. The spectral envelope features...
the present study was concerned with exploring the frequency and linguistic focus of corrective feedback types given by novice and experienced female teachers working with young learners and compared it with those of elementary classes for adults. moreover, it aimed at measuring learners’ acknowledgement of teachers’ corrective feedback in the form of uptake in relation to linguistic coverage o...
abstract pragmatics is the study of communicative action in its sociocultural context. communicative action includes not only using speech acts (such as apologizing, complaining, complimenting, and requesting), but also engaging in different types of discourse and participating in speech events of varying length and complexity. the present study aimed to investigate the assessment of pragm...
Frequency-estimation algorithms devised for complex sinusoids, including the maximumlikelihood (ML) approach, when operating on real sinusoidal signals, suffer from spectral interference due to the superposition of the aliasing components at negative and positive frequencies. This paper introduces a frequency estimation ML-like algorithm, based on a spectral-matching approach, that avoids such ...
