RECEIVED SIGNAL STRENGTH INDICATION (RSSI) OF 2.4 GHZ AND 5 GHZ WIRELESS LOCAL AREA NETWORK SYSTEMS PROJECTED OVER LAND AND SEA FOR NEAR-SHORE MARITIME ROBOT OPERATIONS

The effect of the maritime environment on radio frequency (RF) propagation is not well understood.In this work, we study the propagation of ad hoc 2.4 GHz and 5 GHz wireless local area network systems typically used for near-shore operation of unmanned surface vehicles.In previous work, maritime RF propagation performance is evaluated by collecting

Abstract Background Temperature remarkably affects the growth and metabolism 6.5" Speakers of plants.Tobacco is an important cash crop, and the long-term effects of different growth temperatures (18.5, 23.5 and 28.5 °C, daily average) on growth, development and plastid pigments metabolism of tobacco plants were investigated in this study.Results

Among mobile terrestrial animals, movement among microsites can allow individuals to behaviorally moderate their body temperatures and rates of water loss, which can have important consequences for Collections activity times, growth, fecundity, and survival.Ground-layer vegetation can change the availability and variability of microclimates; howeve

Numerical simulation of an oblique detonation induced by a wedge is performed to investigate the formation and evolution of the oblique cellular detonation structure and the quantitative comparison of the cellular structure of a normal Collections and an oblique detonation.The compressible reactive Euler equations are solved using the seventh-order
