The NUT in the N=2 Superalgebra
, 2009 We study how the supersymmetry algebra extension of N=2 supergravity with central charges describes the NUT charge in a duality-covariant way. The stationary BPS states of N=2 supergravity can be embedded in the flat space solution of the timelike ...

Effect of Hull Forms on Ship Motions and Optimization of Hull Forms for Seakeeping Performance
Journal of the Society of Naval Architects of Japan, 1989 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 ...

Rapid hull modeling methodology based on CAD and CATIA secondary development
Zhongguo Jianchuan Yanjiu, 2020 Objectives In the process of creating a hull model using CATIA, human factors are large and the process is complicated. In order to quickly measure the ship's offsets and adopt them to quickly 3D modeling, this paper presents a ship modeling design ...

Algebraic ship hull surfaces with a main frame from three plane curves in coordinate planes
RUDN Journal of Engineering Research, 2022 One of the important problems of naval architects and designers is a choice of rational ship hull shape. A choice of ship hull form is based often on empirical formulae or on designers’ intuition.

Application of the Design of Experiments and Computational Fluid Dynamics to Bow Design Improvement
Journal of Marine Science and Engineering, 2019 Techniques of the design of experiments (DOE) and computational fluid dynamics (CFD) were applied for improving the bow shape of a tanker hull. Through this, a hull that could reduce the added resistance in waves was derived.

Effect of Hull Form Variations on Slamming and Dynamic Response in a Naval Vessel
Journal of Naval Architecture and Marine TechnologyThis study evaluates the influence of specific hull-form parameters on slamming behavior. The hull of a military frigate was adopted as the baseline geometry, and systematic variations were generated by modifying one form parameter at a time.
