THE TIME DOMAIN ANALYSIS ON MOORED SHIP MOTIONS

A Time-Domain Numerical Study of Passive and Active Anti- Roll Tanks to Reduce Ship Motions

The Motions of a Ship on a Sloped Seabed

In standard diffraction theory it is assumed that the water depth is constant and that the seabed is infinitely large. To account for a local varying bathymetry in shallow water (as it can occur for offshore LNG terminals) it is sometimes considered to introduce a second fixed body on the seabed representing this bathymetry in diffraction theory. Based on the results presented in this paper it ...

Analysis of domain motions in large proteins.

We present a new approach for determining dynamical domains in large proteins, either based on a comparison of different experimental structures, or on a simplified normal mode calculation for a single conformation. In a first step, a deformation measure is evaluated for all residues in the protein; a high deformation indicates highly flexible interdomain regions. The sufficiently rigid parts o...

Analysis of the Relationship between the Business Cycle and Inflation Gap in Time-Frequency Domain

Controlling the business cycle and minimizing the inflation gap are considered as two major goals for monetary policy. Hence, the policymaker will be able to make more decisive decisions with an awareness of the dynamic relationship and causal relationship between these two variables. Accordingly, the present study uses a discrete and continuous wavelet transform to provide a new understanding ...

Time Domain Analysis of the Ventilation around the Partial Immersed Propeller Using Sliding Mesh Method

In this paper a computational method is presented for predicting the unsteady hydrodynamic forces acting on partial immersed propeller (SPP). In order to simulate the unsteady viscous flow around a SPP, a Reynolds-Averaged Navier–Stokes (RANS) solver is used. The time-accurate calculations are made by applying the sliding mesh method. Structured and unstructured mesh techniques are used. ...
