Convex hulls are fundamental geometric tools used in a number of algorithms. This paper presents a fast, simple to implement and robust Smart Convex Hull (S-CH) algorithm for computing the convex hull of a set of points in . This algorithm is based on “spherical” space subdivision. The main idea of the S-CH algorithm is to eliminate as many input points as possible before the convex hull constr...

In this study, we investigated the effect of hull dynamics in shallow water on the hydrodynamic performance of rowing shells as well as canoes and kayaks. An approach was developed to generate data in a towing tank using a test rig capable of reproducing realistic speed profiles. The impact of unsteady shallow-water effects on wave-making resistance was examined via experimental measurements on...

Various forms of Autonomous Underwater Vehicles (AUVs) have evolved to solve different subsea mission requirements, these can be loosely grouped into two types: torpedo style AUVs and hovering AUVs. Torpedo AUVs were initially developed to be launched from torpedo tubes and consequently resemble torpedoes with a propeller and control surfaces at the rear, these vehicles have poor slow speed man...

The outer or inner approximation of the convex hull of a grid point set may be used to speed up the feature extraction process in a shape analysis system. Some properties of these approximations are given.
