According to the features of the high temperature's impacts on inland shipping, the impacts were divided into light, moderate and severe level. Based on the series data of temperature time in seventeen stations which near the coastal area of Middle Yangtze River during the period between 1965 and 2008, the characteristics of climate variations influenced by the high temperature are analyzed and discussed...
Emergency Position Indicating Radio Beacons (EPIRBs), as an interface — offering services of Cospas-Sarsat worldwide plays an essential role in Search and Rescue mission. Regrettably, EPIRBs have a high rate of false activations which may cause — unnecessary expense of Search and Rescue activities. In this paper, — while analyzing the false alert rate and the cost on it, an approach towards improving...
