... unconservative fatigue life estimates. The joint distribution of the last two mode amplitudes is analyzed and found to be polar. Therefore, the three mode amplitudes are mapped to a cylindrical coordinate system, and it is found that cylindrical binning is more efficient, by a factor of more than 2, as compared...

The general case, as it will be obvious later, of the barge being towed in a narrow and shallow canal will be analyzed (Figure 2). The global or coordinate system fixed in space is centered at O. The mathematical...

... is that the equations of motion are written in the two coordinate systems that follow the two ships (see figure 2). The importance of this is that there is no need to rotate all forces to the "Fixed to Earth" system before solving the equations of motion. Large angle analysis is required since the two ships may each...
