precise application of the n fertilizer rate is critical to achieve maximum yield. in major regions, empirical methods were used for determining n fertilizer requirement. these methods cannot take into account variation in management and environmental conditions on determining fertilizer requirement. crop simulation models can provide an alternative means of determining the optimum crop n requi...

Huang presented a trade-off problem, taking both product quality and process adjustment cost into account, to determine the optimum parameters (i.e., the process mean and process variance) of the input characteristic in the transformation model. In Huang’s transformation model, the input characteristic, x, is assumed to be normally distributed and the output characteristic, y, is nominal-the-be...

In the small satellite world, it is becoming increasingly popular to use a constellation of small satellites to do the work previously performed by one large satellite. Implicit in this scenario is the requirement for clusters of small satellites to communicate among themselves via an inter-satellite link (ISL). Traditionally, an ISL has taken the form of a time-division-multiple-access (TDMA) ...
