Non-linear complex principal component analysis nearshore bathymetry
2009/11/11
Complex principal component analysis (CPCA) is a useful linear method for dimensionality reduction of data sets characterized by propagating patterns, where the CPCA modes are linear functions of the ...
VIV analysis of pipelines under complex span conditions
boundary condition (BC) fatigue limit state (FLS) force model (FM) kilometer post (KP) mode shape natural frequency response model (RM) vortex-induced vibration (VIV) ultimate limit state (ULS) unit stress
2011/9/13
Spans occur when a pipeline is laid on a rough undulating seabed or when upheaval buckling occurs due to constrained thermal expansion. This not only results in static and dynamic loads on the flowlin...
An Analysis of the Cabbeling Instability in Sea Water
nonlinear equation sea water Cabbeling Instability
2009/4/3
Due to the nonlinear equation of state of sea water it is possible for the mixture of two Parcels of sea water with the same density but different temperatures and salinities to have a density greater...
An Analysis of 20 Years of Meteorological and Oceanographic Data from Ocean Station N
Meteorological Ocean Station N Oceanographic Data
2009/3/26
Meteorological and oceanographic data for Ocean Station Vessel N (30N, 14OW) are analyzed over 20 years (1951–70) and 7 years (1964–70), respectively. A rainfall estimate is constructed for the 20-yea...
