abstract following innovations in the field of elt, a new topic which has recently attracted a lot of attention is metaphor analysis. although this area of research is still in its infancy in elt, it seems that the idea can shed more light on the puzzle of english language learning and teaching. therefore, the major aim of this study is to analyze language learning and teaching in formal a...
This paper discusses the use of multitemporal remote sensing data for mapping and monitoring land cover in Acre State located in the western Brazilian Amazônia. According to IBGE vegetation maps, the study area is primarily covered by moist tropical forests (“Floresta Ombrofila Aberta”) that has been partially deforested during the last decades. The climate in Acre is classified as Am in the Ko...
the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
Mapping the spatio-temporal characteristics of wetland 19 inundation has important significance to the study of wetland environment and 20 associated flora and fauna. High temporal remote sensing imagery is widely 21 used for this purpose with the limitations of relatively low spatial resolutions. In 22 this study, a novel method based on integration of back-propagation neural 23 network (BP) a...
In this comparative study, the Bayesian and a neural network (the HLVQ) approaches are used to classify multispectral LANDSAT images. The studied area contains several agricultural classes (wheat, flax,....). Some classes are found to be non homogeneous and thus are divided in this study into several subclasses. The Gaussian assumption needed by the Bayesian classifier is thus justified by this...
In paper, LANDSAT multispectral image is classified using several unsupervised and supervised techniques. Pixel-by-pixel classification approaches proved to be infeasible as well as time consuming in case of multispectral images. To overcome this, instead of classifying each pixel, feature based classification approach is used. Three supervised techniques namely, k-NN, BPNN and PCNN are investi...
Land use maps are considered as the most important sources of information in natural resource management. The purpose of this research is to review, model, and predict landslide changes in the 30-year period by LCM model in Shiraz. In this research, TM Landsat 4, 5 and OLI Landsat 8 images were used for 1985, 2000 and 2015 respectively, as well as topographic maps and area coverage. Subsequent ...
In this paper, we present a watermarking technique for hiding an entire image or pattern as a watermark into remotesensing images. In our technique, the Karhunen Loève Transform (KLT) is preliminarily applied on the multispectral image. The most principal component image is used for embedding with a watermark. The embedding process is performed in a middlefrequency subband resulted by a two-dim...
A new data fusion model for high spatial-and temporal-resolution mapping of forest disturbance based on Landsat and MODIS. Disclaimer: The PDF document is a copy of the final version of this manuscript that was subsequently accepted by the journal for publication. The paper has been through peer review, but it has not been subject to any additional copy-editing or journal specific formatting (s...
burnout is a response to the chronic work stress which is prevalent mostly among the people who do people job, like teaching. the purpose of this study was to develop a valid and reliable instrument that can measure burnout in foreign language teachers. although some widely used instruments were developed before which measured burnout in teachers, a specific instrument which include specific sy...
