abstract the present thesis seeks to critically read george orwell’s nineteen eighty-four and animal farm in the light of louis althusser’s thought and theory. the present thesis proceeds to examine and demonstrate althusser’s major concepts including ideological state apparatuses (isas), repressive state apparatuses (rsas), the structure, the subject, and ideological interpellation which r...
abstract: research purpose: the purpose of this research is to identify academic databases assessment factors and criteria at law and political science majors. the necessity of this research is to distinguish academic databases assessment factors and criteria and to identify the most important ones and rank them in order to select an appropriate database according to students’ and faculty memb...
forest classification on the basis of satellite images is a promising technique both for primary map production and for map updating and forest monitoring. for accurate for-est classification into three classes, using mapping by canopy cover density “high spatial resolution satellite images have to be used in order to obtain the required spatial detail” [schneider, 1999]. at the same time, the ...
We examine the issue of sustained measurements of sea level in the coastal zone, first by summarizing the long-term observations from tide gauges, then showing how those are now complemented by improved satellite altimetry products in the coastal ocean. We present some of the progresses in coastal altimetry, both from dedicated reprocessing of the radar waveforms and from the development of imp...
one of the problems in detecting radar targets is the variation of target cross section due to aspect angle; which is named as target fluctuation. this perfectly depends on target geometry and transmitted wavelength and can cause significant loss of detection. one of the solutions to this is improving the radar range resolution. stepped frequency is one of the signals that can improve the range...
As the information carried in a high spatial resolution image is not represented by single pixels but by meaningful image objects, which include the association of multiple pixels and their mutual relations, the object based method has become one of the most commonly used strategies for the processing of high resolution imagery. This processing comprises two fundamental and critical steps towar...
Human groups have considered the Behshahr plain of Mazandaran in the past Due to its particular geographical shape, location between the Caspian Sea and mountains, and the existence of some rivers in the region. However, our knowledge of this area is limited to several published surveys and archaeological investigation of its ancient sites. No detailed research has conducted on the formation of...
Reliable projections of future sea level are vital for coastal communities. Regional deviations from global mean sea level rise are caused primarily by spatial patterns in the various components of sea level change (e.g. melting land ice, thermal expansion, and so on; see Slangen et al. 2012; Perrette et al. 2013; Church et al. 2013) and by wind anomalies associated for example with various cli...
The Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) and satellite altimetry can provide very detailed and accurate estimates of the mean dynamic topography (MDT) and geostrophic currents in China’s marginal seas, such as, the newest high-resolution GOCE gravity field model GOCONS-GCF-2-TIM-R4 and the new Centre National d’Etudes Spatiales mean sea surface model MSS_CNES_CLS_11 ...
the primary goal of the current project was to examine the effect of three different treatments, namely, models with explicit instruction, models with implicit instruction, and models alone on differences between the three groups of subjects in the use of the elements of argument structures in terms of toulmins (2003) model (i.e., claim, data, counterargument claim, counterargument data, rebutt...
