A 3-D time-domain numerical wave tank using a higher-order boundary element method is newly developed in the framework of linear potential theory, and ship waves generated by the standard Wigley model advancing at constant forward speed in otherwise calm water and the resultant steady wave resistance are computed as verification of the computer code developed. A rectangular computational domain...

The concepts of $L$-convex systems and Scott-hull spaces are proposed on frame-valued setting. Also, we establish the categorical isomorphism between  $L$-convex systems and Scott-hull spaces. Moreover, it is proved that the category of $L$-convex structures is  bireflective in the category of $L$-convex systems. Furthermore, the quotient systems of $L$-convex systems are studied.

Abstract This paper provides four theorems on the existence of a free-disposal equilibrium in Walrasian economy: first with an arbitrary set agents compact consumption sets, next highlighting trade-offs involved relaxation compactness assumption, and last two countable endowed weighting structure. The results generalize antecedent literature pioneered by Shafer–Sonnenschein 1975, currently form...

In line with the current research on the ultimate strength assessment of ship hull girders, careful understanding of the collapse behaviour of unstiffened plate elements within the ship hull girders is an important and necessary task. In this paper, the collapse behaviour of unstiffened plates under longitudinal and transverse thrust is studied by elastoplastic large deflection FEM and the char...

Figure 1: Size of hull vs. size of set 1 has a very small number of points on its convex hull in relation to the size of the whole set. In set P2, all points in the set are on the convex hull. Is there an algorithm which is output sensitive in relation to the number of points on the convex hull? It turns out there is such an algorithm KirkpatrickSeidel Marriage Before Conquest. Its complexity, ...

A fast SVM learning algorithm is proposed according to incremental learning and center convex hull operator. It is established on analyzing the relevance of support vector and convex hull from the angle of calculation geometry. The convex hull of current training samples is solved in the first place. Further, Euclidean distance elimination is applied to convex hull. Meanwhile, every time when t...

Hydrodynamic performance of a marine vessel mainly depends on the frictional and pressure resistance. Pressure drag reduction could be achieved by improving the shape of the vessels with implementation of modern hull forms. Hull forms optimization techniques could also be used for this purpose. Other techniques are needed to deal with the viscous portion of the total resistance, which is mainly...
