The result is a large dataset covering a range of conditions. The microSWIFT is a small wave buoy equipped with a GPS module and Inertial Measurement Unit (IMU) …
WebDetermining Lamb wave dispersion curves when measuring phase and group velocity values at a fixed frequency is now a common and relevant task. In most cases, in order to solve such a problem, it is necessary to know the exact properties of the material, particularly its thickness. In experimental methods, Lamb wave parameters are … WebNov 2, 2012 · If you believe the input signal to have a positive value, you require that the signal dip down below a chosen threshold value -T in order to declare a real zero crossing. Likewise, you require that the signal rise back up above the threshold T in order to declare that the signal has oscillated back to positive again.

The zero upcrossing (or downcrossing) method is the main method used to separate waves. In the time domain, the different waves are ranked in order of …
WebThe conventional appraoch is to determine limiting wave conditions for these kind of operations. These limits are based on statistics. Only when the chances of a limit crossing event are sufficiently low, performing the critical step is allowed. This can only be acheived by applying significant safey factors.
WebApr 28, 2024 · Bimodal spectrum wave conditions, known as crossing seas, can produce extreme waves which are hostile to humans during oceanic activities.
