Non-linear complex principal component analysis of nearshore bathymetry
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...
A Finite-Element Solution Procedure for the Interpolation of Current Data in Complex Regions
Finite-Element Solution Complex Regions Current Data
2009/2/19
A finite-element solution technique is introduced to develop current patterns subject to geostrophic and Ekman dynamics for an irregular continental shelf region. The interpolation bases set of functi...
An Improved Bound for the Complex Phase Speed of Baroclinic Instability
Complex Phase Speed Baroclinic Instability
2008/7/4
An improved bound is obtained for the radius of the semicircle in the complex plane containing the complex phase speed of baroclinically unstable plane wave disturbances. In the limit of long waves, t...
