The Soil Moisture Active Passive (SMAP) mission was launched January 31st, 2015. It is designed to measure the soil moisture over land using a combined active / passive L-band system. Due to the Aquarius mission, L-band model functions for ocean winds and salinity are already mature and may be directly applied to the SMAP mission. In contrast to Aquarius, the higher resolution and scanning geometry...
An optimization method base on Genetic Algorithms is used to calculate the control capability of the dynamic positioning system of a ship. Real number coding is used as the code of Genetic Algorithms, and the sum of ratio which the real force of five propellers occupy each maximum force at a given wind velocity is considered as the fitness function, and roulette wheel selection is chosen as the selection...
