The present study was designed to investigate the impact of applying fill-in-the-map and construct-a-map techniques on EFL learners’ knowledge of tenses. To this end, sixty EFL elementary female students, who were selected based on their performance on a standardized teacher-made proficiency test, were randomly assigned into two equal experimental and control groups. In order to be convinced of...

The estimation of accuracy of thematic maps derived from remotely sensed data used in conjunction with a geographic information system is presented. A systematic random sampling techique is proposed to asses the accuracy. The main objective of this work is the determination of the optimal sampling intensity and the appropriate sample size used to assess the accuracy. The data set used is a Land...

DC coefficient restoration scheme is a technique which can be used to increase the compression ability of transform image coding by not transmitting the DC coefficients but estimating them from the transmitted AC component. In the last decade, the minimum edge difference criterion is used in the scheme. However the criterion fails at the locations where the discontinuities are along the block b...

The study area, located in the southern section of the Central Iranian volcano–sedimentary complex, contains a large number of mineral deposits and occurrences which is currently facing a shortage of resources. Therefore, the prospecting potential areas in the deeper and peripheral spaces has become a high priority in this region. Different direct and indirect methods try to predict promising a...
