Our approach to the task of intrinsic plagiarism detection uses a vectorspace model which eschews surface features in favor of richer extrinsic features, including those based on latent semantic analysis in a larger external corpus. We posit that the popularity and success of surface n-gram features is mostly due to the topic-biased nature of current artificial evaluations, a problem which unfo...

Determining the flow accumulation threshold (FAT) is a key task in extraction of river networks from digital elevation models (DEMs). Several methods have been developed to extract Digital Elevation Models. However, few studies considered geomorphologic complexity FAT estimation and network extraction. Recent estimated influencing factors’ impacts on length or drainage density without consideri...

About 80 percent of Iran is arid and semi-arid and about 35 percent of this area is susceptible to desertification hazard. Therefore desertification assessment and identification of the most important criteria for the assessment of risk and a basis for development of management plans is essential. This research was conducted in the semi-arid region of Agh-Band in the Golestan province, Iran wit...

Shallow earth translational slides and earth flows, affecting colluvial soils derived by the weathering of the clayey bedrock, are a recurrent problem causing damage to buildings and roads in many areas of Apennines. The susceptibility assessment, e.g. slope stability models, requires the preliminary characterization of these superficial covers (lithology, geotechnical and hydraulic parameters)...

This study investigated the acquisition of grammatical aspect by Iranian EFL learners. The main question addressed in this study was whether Iranian EFL learners could distinguish conditions under which they must use either the perfective aspect  or imperfective aspect. A group of 110 adult, Persian-Speaking learners of English both at BA and MA levels Took a Michigan test based on which they w...
