User’s hand effect on efficiency of 2-port 5 GHZ mobile terminal antennas

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

Evaluation of Performance of Mobile Terminal Antennas

Analysis of Mobile Terminal Diversity Antennas

Abstract Antenna diversity has for many years been deployed at the base station to provide significant diversity gain. More recently diversity has also been implemented at the mobile and it has been observed through measurement that antennas still give low correlation even when closely spaced. This paper analyses why de-correlation exists mainly due to angular diversity effects from the two ant...

effect of oral presentation on development of l2 learners grammar

this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
