More than 100 years of Arctic sea ice volume reconstructed from ships' logbooks（图）
Arctic sea ice volume reconstructed ships logbooks
2019/10/21
Our knowledge of dwindling sea ice coverage in the Arctic Ocean comes mostly through satellites, which have imaged sea ice from above since 1979. The University of Washington Pan-Arctic Ice Ocean and ...
Ships Passing in the Night or a Marriage Made in Heaven?
Ships the Night Marriage Made Heaven
2015/8/4
This issue of Oceanography celebrates a seminal event: the joint conference of The Oceanography Society (TOS) and Oceanology International Americas 2001 (OIA2001). The TOS membership is intimately fam...
The ocean has provided an important means of commerce and transport for centuries and does so to this day. With the ocean covering roughly 70% of Earth's surface, much maritime activity occurs well ou...
Chaotic Roll Motions of Ships in Regular Longitudinal Waves
parametric resonance Lyapunov characteristic exponents longitudinal waves.
2011/9/9
Parametric resonance can lead to dangerously large rolling motions, endangering the ship, cargo and crew. The QR-factorization method for calculating (LCEs) Lyapunov Characteristic Exponents was intro...
Applying the vantage PDMS to jack-up drilling ships
Vantage PDMS component database rate database bolt jack-up drilling ships
2011/9/13
The plant design management system (PDMS) is an integrated application which includes a database and is useful when designing complex 3-D industrial projects. It could be used to simplify the most dif...
Review of prediction techniques on hydrodynamic impact of ships
review prediction techniques hydrodynamic impact
2011/9/13
This paper presents the survey and assessment of the estimation techniques on hydrodynamic impact. The description and definition of hydrodynamic impact are presented, and the categorization of predic...
Classifying ships by their acoustic signals with a cross-bispectrum algorithm and a radial basis function neural network
acoustic vector signal cross-bispectrum feature extraction RBFNN ship classification
2011/9/9
An algorithm for estimating the cross-bispectrum of an acoustic vector signal was formulated. Composed features of sound pressure and acoustic vector signals are extracted by the proposed algorithm an...
Research on roll stabilization for ships at anchor
at anchor anti-rolling lift-generation model fluent simulation
2011/9/14
With the increasing importance of ocean exploitation,providing anti-rolling stability for ships at anchor has become more and more important. The lift-generation theory of traditional fin stabilizers ...
