Geographic Information Systems (GIS) and spatial databases are inherently suited for fuzziness, because of the uncertainty inherent in the assimilation, storage, and representation of spatial data. These objects may also have naturally occurring imprecise boundaries. It is difficult to store and represent these objects while continuing to demonstrate the uncertainty inherent in the objects. Thi...
muhammad ibn muhammad ibn numan, known as "shaykh mufid," one of the great imamiye theologians and jurists in the fourth and early fifth century , had comprehensive mastery of both rational and traditional topics and exerted his influence upon both his contemporary and future scholors. he is considered to be one of the top imamiye scholars who spent his lifetime teaching, learning and authorin...
in reality, most structures involved in geotechnical engineering are three dimensional in nature, and although in many, plane strain or axisymmetric approximations are reasonable, there are some, for which 3-d treatment is required. the quantity of data, and the size of the various vectors and matrices involved in such analysis, increase dramatically. this has sever implications for computer r...
Hyperspectral sensors are important tools in monitoring the phenomena of the Earth due to the acquisition of a large number of spectral bands. Hyperspectral image classification is one of the most important fields of hyperspectral data processing, and so far there have been many attempts to increase its accuracy. Spatial features are important due to their ability to increase classification acc...
The term Digital Earth was coined in 1998 by Al Gore proclaiming a three-dimensional multiresolution representation of the Earth’s surface holding georeferenced data of any kind (ISDE, 1998). Part of this vision is the ubiquity of observation systems, enabling a digital representation of features such as environmental phenomena with a high spatial and temporal resolution. World wide a vast amou...
The purpose of the present study is to propose a scheme to estimate whole-body averaged specific absorption rate (WBA-SAR) in the whole-body resonance and GHz frequency regions. The motivation is that WBA-SARs in the child models in these frequency regions have been reported to approach to the basic restrictions in the international guidelines/standards. In the resonance frequency region, we pr...
The use of supra-dietary doses of chemical antioxidants has attracted increasing interest as a possible primary and secondary cancer prevention strategy. It is possible that some cancer patients have an inherently impaired capacity to contend with oxidative stress because of genetic or environmental factors. Specifically, higher levels of intracellular antioxidants may protect against chromosom...
abstract over the past two decades, applied linguists and language teachers have shown a great deal of interest in genre-centered approaches , mainly because of pedagogic concerns . this has been due to the need to help non-native readers enhance their ability to understand academic and scientific texts. following swales’ (1981) works on genre analysis, studies of different sections of resear...
