Research ArticleOpen accessIn the keywordsComparison and Analysis of Vertical Coherence in the Shallow Water of Two ocean regionV. G. Sivakumar, V. Rajendran, R. SaranyaNoise characteristics at shallow water is highly variable due to wave guide nature of the shallow water environment, reflection of noise from the bottom surface; due to biological activities and also due the sound speed in shallow water vary substantially. Thus noise field characterization is complex in shallow water. The ambient noise data was collected in the shallow water of … …American Journal of Applied Sciences, Vol. 10, Issue 6 · 5 Jun 2013 · 6,488 accessesView PDF Cite

Research ArticleOpen accessIn the abstractTemperature Effect on Uncooled Semiconductor Laser Diode to the Network Performance SystemMohammad Syuhaimi Ab-Rahman, Nurain Izzati ShuhaimiProblem statement: The characteristics of a laser diode are highly dependent on the temperature of the laser chip. Thus, the effect of temperature on the network performance of uncooled semiconductor laser diode are studied by simulating its equivalent electrical circuit, developed from the rate equations that governing optical components directly into an electrical simulation framework. Approach: The simulations are carried … …Journal of Computer Science, Vol. 8, Issue 4 · 8 Feb 2012 · 6,621 accessesView PDF Cite
