Second Order Statistics and Discrete-Time Detection Modeling for Partially Saturated Processes
(Acoustical Society of America, 1985-03)
The basic problem in underwater detection is formulated under the general assumptions of partially saturated propagation of narrow‐band and acoustic signals. Expressions for the joint probability density function (PDF) of ...
Redesign of marine structures by perturbation
(Elsevier, 1988)
Finite element (FE) methods are extensively used for analysis of static and dynamic behavior of marine structures. Often predicted response is unacceptable from the point of view of design or operation. Improvement of ...
Full scale wake and boundary layer instrumentation feasibility study
(Elsevier, 1980)
Fluid-flow measuring devices intended for full scale use were designed and tested. One device consisted of a rake supporting different types of pitot tubes. This will be used to obtain a velocity profile of the boundary ...
Ship Springing - An Experimental and Theoretical Study
(University of Michigan, 1980-05-01)
The results of an experimental and theoretical study investigating the main hull girder vibrations of Great Lakes ore carriers are presented. The source of excitation is considered to be the incident waves. The emphasis ...
Adaptive Path Control of Surface Ships in Restricted Waters
(University of Michigan, 1980-03-01)
The feasibility and effectiveness of using an integrated system for the adaptive control of a surface ship along a prescribed path in restricted waters is investigated. The controller consists of four major components ...
Static Analysis of Marine Risers
(University of Michigan, 1981-05-01)
The static riser design problem is formulated and solved. A two dimensional, small slope, small deflection, linear model for bending of vertical circular tubular beams under tension, internal mud_static and external ...
Water Waves Generated by a Slowly Moving Two-Dimensional Body, Part II
(University of Michigan, 1982-05-01)
A solution is obtained, valid asymptotically as speed approaches zero, for the waves generated behind a two-dimensional surface_-piercing body moving ahead at constant speed U. The method of matched asymptotic expansions ...
A Second Look at Measures of Merit for Ship Design
(University of Michigan, 1980-08-01)
My purpose in writing this little book is to discuss the relative virtues and shortcomings of the several measures of merit in current use in ship design. In particular, I want to compare the two criteria most popular with ...
Water Waves Generated by a Slowly Moving Two-Dimensional Body, Part I
(University of Michigan, 1982-05-01)
Low-speed motion of a ship leads to a singular perturbation problem as speed approaches zero, since waves occur only in a boundary layer of vanishing thickness at the free surface. The complete solution consists of the ...
Some Observations on Ship Manning Developments in Northern Europe, and Implications for Design
(University of Michigan, 1983-11-01)
A Report to the Institut fur Schiffs und Meerestechnik of Technische Universitat Berlin.&&In this report you will find a summary of the interwoven economic, technical, and social factors that are forcing change in the ...
