High speed digital imaging of cavitating vortices
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1998-05)
Researchers at the Cavitation and Multiphase Flow Laboratory of the University of Michigan worked in conjunction with Princeton Scientific Instruments (PSI) engineers to employ a new digital imaging system in the study ...
Discrete-time Detection Modeling for Unsaturated Ocean Acoustic Propagation
(Acoustical Society of America, 1983-11)
The basic problem in ocean acoustic detection is formulated under the assumption of unsaturated sound propagation. The latter essentially amounts to a constant signal plus Gaussian noise. Detection is defined as occurring ...
Advances in Decentralized Single-Beacon Acoustic Navigation for Underwater Vehicles: Theory and Simulation
(IEEE, 2010-09-1)
This paper reports the theory and implementation
of a decentralized navigation system that enables simultaneous
single-beacon navigation of multiple underwater vehicles. In
single-beacon navigation, each vehicle uses ranges ...
Prediction of steel plate deformation due to triangle heating using the inherent strain method
(Springer-Verlag; JASNAOE, 2005-12)
In a shipyard, line heating and triangle heating are two major processes carried out by skilled workers to form curved plates in various shapes under various heating conditions. There have been many studies on line heating, ...
Seakeeping Standard Series for Oblique Seas (a Synopsis)
(Elsevier, 1999-08-25)
The seakeeping performance in oblique seas for a series of 72 cruiser-stern hull forms has been evaluated analytically and is presented in a systematic way. The hull form series have been created by Loukakis and Chryssostomidis ...
The experimental and theoretical evaluation of a twin-flap wave-energy absorbing device
(Elsevier, 1983)
A series of model experiments with a twin-flap wave-energy absorbing device is described, and the results compared with numerical predictions based on theoretical work reported by Srokosz and Evans (1979). Measurements ...
A Nonlinear Approach to the Multiorigin, Multidestination Fleet Deployment Problem
(Wiley, 1989-08)
The problem of minimal-cost operation of a fleet of ships carrying a specific amount of bulk cargo from several origin ports to several destination ports during a specified time interval is examined. The fuel oil cost, a ...
Time-domain computations for floating bodies
(Elsevier, 1994)
A review of the research carried out at the University of Michigan and elsewhere on the use of time-domain panel methods to compute the hydrodynamic forces acting on floating bodies is presented. Both linear and fully ...
Visually Mapping the RMS Titanic: Conservative Covariance Estimates for SLAM Information Filters
(SAGE, 2006-12)
This paper describes a vision-based, large-area, simultaneous localization and mapping (SLAM) algorithm that respects the low-overlap imagery constraints typical of underwater vehicles while exploiting the inertial sensor ...
Nonisothermal model of glass fiber drawing stability
(Steinkopff-Verlag; Springer Science+Business Media, 1996-11)
Draw resonance is caused by a constant speed winder that leads to non-constant axial forces (Schultz, 1984). The well studied isothermal Newtonian fiber drawing predicts very modest critical draw ratios (around 20, much ...
