... the actual measured wind field more realistically based on the measurement data. However, due to the high cost and difficulty of wind field measurement, the number of measurement points that can be set in the target wind field is limited. On this basis, a method was proposed in this study to reconstruct...

... was conducted in a wave flume to examine the method, utilizing a thermal stereo system to acquire infrared images of the wave surface. Stereo reconstruction was performed to obtain instantaneous three-dimensional wave fields at each moment. The wave time series were extracted from point cloud sequences...

... ABSTRACT The environmental loads can be reconstructed from physical model tests and subsequently utilized to conduct a virtual model test with a numerical full-depth system. The time histories of environmental loads are applied to the center of gravity of the numerical model to acquire...

... these clear and complex wake modes. In addition, we conducted time and frequency analyses on these 12 subspaces. To compare the reconstructed wakes with the original ones, we utilized the linear mode summation method for reconstruction. Fig. 4 Variation in phase-averaged wake formation observed in three...

... ABSTRACT We show how to reconstruct the vortex-induced vibrations of a riser from experimental strain measurements using a machine learning framework. We employ a modal decomposition technique followed by inference of the expansion modes using a two-stage optimization routine. A stochastic...

Under different thickness of refractive plane, synthetic...

... ABSTRACT Due to problems such as equipment failure, transmission delay, and signal loss, the original AIS (Automatic Identification System) data generally need to be preprocessed before further analysis. In this paper, we propose a novel approach for vessel trajectory reconstruction combining...

... background Cartesian grid, we propose the RBF-based h-adaptive refinement method to represent the complex boundary, in which the RBF is also used as a geometric refinement indicator. The method is validated by the geometric modeling and reconstruction of a sphere and the typical KCS hull. In addition, we...
