A new risk assessment method for anchor dragging is proposed. Using several kinds of information that can be commonly obtained on the navigational bridge ships, touch down point chain to seabed estimated based ship’s equations motion. Firstly, accelerations and velocities ship are numerically evaluated using GPS data. Secondly, hydrodynamic forces, such as added mass, damping force wind force, ...

A method is described for determining small amounts of water and other volatile substances present as impurities in various organ ic and inorganic compounds. The impurity is separated by fusing the substance in a cell attached to a collecting system and allowin g it to freeze slowly while the vapors are collected by pumping them into a t rap of known volume, cooled by liquid air. When the trap ...

It has been recently demonstrated [M. P. Blodgett and P. B. Nagy, J. Nondestruct. Eval. 23, 107 (2004)] that eddy current conductivity measurements can be exploited for near-surface residual stress assessment in surface-treated nickel-base superalloy components. To quantitatively assess the prevailing residual stress from eddy current conductivity measurements, the piezoresistivity coefficients...

A numerical method for solving the equations modeling acoustic scattering in three dimensions is presented. The method is capable of handling several dozen scatterers, each of which is several wave-lengths long, on a personal work station. Even for geometries involving cavities, solutions accurate to seven digits or better were obtained. The method relies on a Boundary Integral Equation formula...
