Statistical Methods for Planning Diesel Engine Overhauls in the U. S. Coast Guard
(American Society of Naval Engineers; Wiley, 2011-04)
The United States Coast Guard has recently investigated new strategies to maintain cutter propulsion diesel engines. Reliability centered maintenance with statistical methods may allow the time between costly scheduled ...
A VORTEX LATTICE METHOD FOR HIGH-SPEED PLANNING
(John Wiley & Sons, Ltd, 1996-03-30)
A three-dimensional numerical model using vortex lattice methods (VLMs) is developed to solve the steady planning problem. Planing hydrodynamics have similarities to the aerodynamic swept wing problem—the fundamental ...
Initial Results in Underwater Single Image Dehazing
(IEEE, 2010-09-20)
As light is transmitted from subject to observer it is absorbed and scattered by the medium it passes through. In mediums with large suspended particles, such as fog or turbid water, the effect of scattering can drastically ...
Highlight-line algorithm for realtime surface-quality assessment
(Elsevier, 1994-04)
A new method of surface-quality assessment is presented. The model of highlight lines is introduced, and its properties and applications in surface-quality evaluation are demonstrated. The differential equation of the ...
The complementary RANS equations for the simulation of viscous flows
(John Wiley & Sons, Ltd., 2005-05-20)
A complementary set of Reynolds-averaged Navier–Stokes (RANS) equations has been developed for steady incompressible, turbulent flows. The method is based on the Helmholtz decomposition of the velocity vector field into a ...
Preliminary Deep Water Results in Single-Beacon One-Way-Travel-Time Acoustic Navigation for Underwater Vehicles
(IEEE, 2009-10-10)
This paper reports the development and experimental
evaluation of a novel navigation system for underwater
vehicles that employs Doppler sonar, synchronous clocks, and
acoustic modems to achieve simultaneous acoustic ...
Topology redesign for performance by large admissible perturbations
(Springer-Verlag, 2006-02)
A methodology is developed for optimal structural topology design subject to several performance constraints. Eight-node solid elements are used to model the initial structure, which is a uniform solid block satisfying the ...
An Efficient Single-Screw 11 000 TEU Containership: The Suez Max SS
(Society of Naval Architects and Marine Engineers (SNAME), 2001-10-01)
The ability to transport containers with the least cost at currently required service speeds of approximately 25 knots to maintain a regular operating schedule is the goal of every post-panamax containership operator. The ...
Part-load optima in bottoming-cycles
(Elsevier, 1987-07)
It is assumed that optimal steam conditions for a Rankine bottoming-cycle are those that produce the greatest power output. It is then demonstrated that optimal steam conditions are a function of steam-generator pinch-temperature ...
A Sequential Hypothesis Testing, Optimal Stopping Problem in Underwater Acoustic Detection
(Acoustical Society of America, 1984-03)
A sequential hypothesis testing, optimal stopping problem in underwater acoustic detection is formulated and solved using dynamic programming. The problem calls for deciding whether acoustic signals being received over ...
