Hull Vane (HV) is an energy-saving appendage introduced by BV company to reduce total ship resistance. Shapewise, HV a hydrofoil wing transversely fixed at the transom bottom of hull. In this paper, data-driven shape optimization method proposed for HV. To avoid time-consuming resistance evaluation designs via viscous flow solver, we develop Machine-Learning (ML) based model that predicts hull'...

The exact order of mixing for zero-dimensional algebraic dynamical systems is not entirely understood. Here non-Archimedean norms in function fields of positive characteristic are used to exhibit an asymptotic shape in non-mixing sequences for algebraic Z-actions. This gives a relationship between the order of mixing and the convex hull of the defining polynomial. Using these methods, we show t...

In this paper, a novel approach to shape from multiple cues is further refined and applied to the task of combining contours with local brightness information. The approach, furtheron called the sculptor's principle, does not attempt to construct an 'optimum' solution but rather finds an enclosing volume that must contain the true solution. Shape from contours algorithms only provide accurate r...

We present a fast algorithm to compute an optimal rec-tilinear Steiner tree for extremal point sets. A point set is extremal if each point lies on the boundary of a rectilinear convex hull of the point set. Our algorithm can be used in homotopic routing in VLSI layout design and it runs in O(k 2 n) time, where n is the size of the point set and k is the size of its rectilinear convex hull.

the most promising method for micro scale energy scavenging is via vibration energy harvesting which converts mechanical energy to electrical energy by the effect of coupling between electric fields and mechanical variables. using piezoelectric cantilevers is the most common method for vibration energy harvesting. changing the shape of the cantilevers can lead to changing the generated output v...
