Hydrodynamic forces acting on cylinders oscillating at small amplitudes
(Elsevier, 1991-01)
The hydrodynamic forces resulting from small-amplitude harmonic oscillations of arbitrarily shaped cylinders are considered both experimentally and theoretically. The fluid is assumed to be initially at rest. The theoretical ...
Level Crossing Probabilities for Multipath Acoustic Processes with Bimodal Spectra
(Acoustical Society of America, 1990-05)
A general method of evaluating upcrossing probabilities for a class of random processes consisting of two narrow_band signals is presented. One of the two significant frequencies of the corresponding bimodal spectra is ...
Three-dimensional desingularized boundary integral methods for potential problems
(John Wiley & Sons, Ltd, 1991-05-05)
The concept of desingularization in three-dimensional boundary integral computations is re-examined. The boundary integral equation is desingularized by moving the singular points away from the boundary and outside the ...
Large deformation three-dimensional static analysis of deep water marine risers
(Elsevier, 1985-10)
The problem of static three-dimensional, nonlinear, large deformation response of a marine riser is formulated within small strain theory and solved numerically. This type of analysis is necessary, for the new generation ...
Lagrangian velocity profiles in the wake of a high speed vessel
(Elsevier, 1994-02)
A video imaging technique is employed in a towing basin to obtain high resolution surface Lagrangian velocity observations in the centerline wake region of a high speed, twin screw surface vessel. Approximately 30,000 ...
Chebyshev pseudospectral method of viscous flows with corner singularities
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1989-03)
Chebyshev pseudospectral solutions of the biharmonic equation governing two-dimensional Stokes flow within a driven cavity converge poorly in the presence of corner singularities. Subtracting the strongest corner singularity ...
Exactly Sparse Extended Information Filters for Feature-Based SLAM
(SAGE, 2007-04)
Recent research concerning the Gaussian canonical form for Simultaneous Localization and Mapping (SLAM) has given rise to a handful of algorithms that attempt to solve the SLAM scalability problem for arbitrarily large ...
The velocity potential and the interacting force for two spheres moving perpendicularly to the line joining their centers
(Kluwer Academic Publishers; Springer Science+Business Media, 1993-05)
The velocity potential around two spheres moving perpendicularly to the line joining their centers is given by a series of spherical harmonics. The appropriateness of the truncation is evaluated by determining the residual ...
One Optimization of an Earlier Model of Virtual Downtown Ann Arbor
