Bottom intake is an intake structure which can be considered as an alternative for regular intakes in mountain streams Water in in taking from river are very vast and complicated issues, each project has special characteristics which should be considered. Water intake from riveris generally based on Pump and gravity method. The gravity method is more useful and common because of continuity and ...

This study set out to explore whether different input enhancement tasks as implicit instruction techniques had any significant impact on the intake of causative verbs in English as a foreign language among Iranian EFL learners. For this purpose, three intact classes consisting of 75 male and female intermediate L2 learners were randomly divided into three conditions: simultaneous grammar consci...

This study was conducted to investigate the effect of meaning-focused versus form-focused input-oriented and output-oriented task-based instruction on elementary level Iranian EFL Learners’ vocabulary comprehension and recall. For this purpose, a sample of 120 male students from a private school in Tehran was selected through convenience sampling and based on availability. The participants were...

This research addresses the mixed-model assembly line (MMAL) by considering various constraints. In MMALs, several types of products which their similarity is so high are made on an assembly line. As a consequence, it is possible to assemble and make several types of products simultaneously without spending any additional time. The proposed multi-objective model considers the balancing and sequ...

T he role of Sm addition on water gas shift performance Re/ceria was studied. A redox cycle between Ce4+ and Ce3+ ceria support by oxygen vacancies generation is one the elementary step in mechanism. In this work, we have attempted to enrich content at surface Re/doped enhance performance. The reaction carried out over Re/Sm-doped catalysts with different contents (0, 5, 10, 15 wt%). H2-TPR exp...

The paper deals with the conceptual design of cable-driven parallel robot which will be used for inspection and monitoring tasks in production process. reason need vision based control process is described introduction. Furthermore, mechanisms kinematic structure are described, as well their usage industry sports broadcasts. On that basis, there proposed cable driven (CDPR) desired task visual ...

This paper introduces a novel way to detect metrical structure in music. We introduce a way to compute autocorrelation such that the distribution of energy in phase space is preserved in a matrix. The resulting autocorrelation phase matrix is useful for several tasks involving metrical structure. First we can use the matrix to enhance standard autocorrelation by calculating the Shannon entropy ...
