Research on the Deep Learning Technology in the Hull Form Optimization Problem
A high−accuracy objective function evaluation method is crucial in ship hull form optimization. This study proposes a novel approximate ship hull form optimization framework using the deep learning technology, deep belief network algorithm. To illustrate

VIRTUE : integrating CFD ship design [PDF]
Novel ship concepts, increasing size and speed, and strong competition in the global maritime market require that a ship's hydrodynamic performance be studied at the highest level of sophistication. All hydrodynamic aspects need to be considered so as to

Effect of Hull Forms on Ship Motions and Optimization of Hull Forms for Seakeeping Performance
It is of importance to design a ship which has a good seakeeping performance in her sea-lane. It is, however, hard to say that an optimization of the hull form for seakeeping performance has been sufficiently carried out from the seakeeping point of view at the initial design stage of a merchant ship so far, because it has been difficult to make clear ...

Hull Form Optimization Based on From Parameter Design
Abstract Hull form generation and variation methods to be mainly discuss ed in this study are based on the fairness optimized B-Spline form parameter curves (FOBFC). These curves can be used both as indirect modification function for variatio n and as geometric entities for hull form generation.

Border bases and order ideals: a polyhedral characterization
Border bases arise as a canonical generalization of Gr\"obner bases. We provide a polyhedral characterization of all order ideals (and hence border bases) that are supported by a zero-dimensional ideal: order ideals that support a border basis correspond

Achieving Drag Reduction with Hullform Improvement in Different Optimizing Methods
In general, evaluation of ship hydrodynamic efficiency could be produced by an energy-efficient and concentrated cost function. An optimization method with the representation of hull geometry is one of the preliminary design steps that are most ...

Two-Term Disjunctions on the Second-Order Cone
Balas introduced disjunctive cuts in the 1970s for mixed-integer linear programs. Several recent papers have attempted to extend this work to mixed-integer conic programs.
