the role of application of dynamic assessment approach in improvement of iranian efl writing performance at different language proficiency levels
the present study sought to investigate the role of dynamic assessment (da) in improvement of iranian efl writing performance at different language proficiency levels. to this end, after conducting the quick placement test, 60 iranian efl learners were assigned to two groups with different language proficiency levels. in both groups each participant wrote two compositions, one before and one af...
Performance Improvement of PEM Fuel Cells Using Air Channel Indentation; Part I: Mechanisms to Enrich Oxygen Concentration in Catalyst Layer
A three dimensional, compressible, steady, one phase flow of reactant-product mixture in the air side electrode of proton exchange membrane fuel cell (PEMFC) is numerically studied in this paper. The mixture is composed of three species: oxygen, nitrogen and water vapor. The performance of the cell is enhanced by partial blockage of the flow field channels. Various types of these blocks also ca...
متن کاملPerformance Improvement of IEEE 802. 11a Receivers Using DFT based Channel Estimator with LS Channel Estimator
In this paper the performance of one of the most widely deployed Wireless Local Area Networks (WLANs) based on IEEE 802. 11a standard has been analyzed using different modulation technique and convolution coding rates. The IEEE 802. 11a standard uses Orthogonal Frequency Division Multiplexing (OFDM) technique. In this analysis the channel estimation is pilot symbol based. A particular method pr...
متن کاملCharacteristics of Underground Channel for Wireless Underground Sensor Networks
Wireless Underground Sensor Networks (WUSN) constitute one of the promising application areas of the recently developed wireless sensor networking techniques. The main difference between WUSN and the terrestrial wireless sensor networks is the communication medium. The propagation characteristics of electromagnetic (EM) waves in soil and the significant differences between propagation in air pr...
متن کاملGas Drainage Improvement in Underground Coal Mines
Effective gas management is vital to the success of the longwall mining in the Bulli seam, in the Southern Coalfield, Sydney Basin, NSW, Australia. The evolution of gas drainage methods and practices are discussed with respect to gas type, gas drainage lead time and prevailing geological conditions. Both underground to inseam drilling and surface to inseam drilling techniques are described at b...
متن کاملAn Analytical Study of Reproductive Performance in Gir Cows
Today India stands first in milk production in the world but average consumption is still below the FAO recommended average. Gir is a milch breed, received less attention from development perspectives; hence exploration in improving its production potentiality is required. Reproduction management of livestock is vital to successful dairying, which is governed via several parameters, viz, age at...
