Closed-form Approximations and Series Representations for Partially Saturated Ocean Acoustic Processes
(Acoustical Society of America, 1988-04)
An approximate, closed‐form expression for the value of the integral encountered in the calculation of the probability density function (PDF) of the envelope of a partially saturated ocean acoustic process is obtained. ...
A singular finite element for Stokes flow: The stick–slip problem
(John Wiley & Sons, Ltd, 1989-11)
Abrupt changes in boundary conditions in viscous flow problems give rise to stress singularities. Ordinary finite element methods account effectively for the global solution but perform poorly near the singularity. In this ...
The generation of digital random time histories
(Elsevier, 1982)
"A method to generate digital random time histories is described. A random number sequence is shaped to give the desired spectral density curve. This finite set of numbers is then Inverse Fast Fourier Transformed (IFFT). ...
Probabilistic Torsional Vibration Analysis of a Marine Diesel Engine Shafting System: The Level Crossing Problem
(ASME, 1989-12)
A probabilistic approach to the torsional vibration problem of a marine diesel engine shafting system has been developed. In this analysis, the shafting shear stress is found to be a Gaussian, harmonizable cyclostationary ...
A finite element analysis of beams on elastic foundation including shear and axial effects
(Elsevier, 1987)
A displacement finite element method for analyzing a beam on continuous elastic foundation is presented. A three-dimensional model which accounts for the effects of both the Filonenko-Borodich and Pasternak foundation ...
Main Principles of Modern Superstructure Design
(University of Michigan, 1983-12-01)
Translated from Norwegian by Atle Ellefsen, Edited by Harry Benford&&Please note that this is the second of a three-_part series of papers dealing with current trends in Scandinavian ship manning practices and effects on ...
Compendium of Ship Motion Calculations Using Linear Time-Domain Analysis
(University of Michigan, 1988-07-01)
Over the past four years a three-dimensional time-domain seakeeping computer code has been developed at The University of Michigan. The code uses linear system theory to determine the hydrodynamic forces acting on a vessel ...
