We explore one method for finding the convex hull of certain mixed integer sets. The approach is to break up the original set into a small number of subsets, find a compact polyhedral description of the convex hull of each subset, and then take the convex hull of the union of these polyhedra. The resulting extended formulation is then compact, its projection is the convex hull of the original s...

In line with technological developments, many studies have led to the factors that consider hull shape planning. Therefore, innovations in form planning are primary basis for obtaining a is considered efficient reducing ship resistance and fuel consumption. This study aims modify design of monohull transform it into catamaran while maintaining total length Displacement ratio. The model used Mon...

Floating offshore wind turbine (FOWT) is an innovative technology with little industry guidance for its hull design. Various FOWT floaters different shapes claim to support the same turbines. Structural integrity and material expense analyses of pontoon were conducted, it was found that some configurations, such as those every two columns connected by both bracing, have advantages over others. ...

Three hundred and sixty one-day-old chicks (Arian) were used in a completely randomized design with five treatments and four replicates for each treatment. The experimental treatments included: control group (without barley) with and without enzyme, 20% hulled barley with and without enzyme, 20% hull-less barley with and without enzyme. Body weights, feed intake and feed conversion were determi...

Three-dimensional shape retrieval is a problem of current interest in several different fields, especially in the mechanical engineering domain. There exists a large body of work in developing representations for 3D shapes. However, there has been limited work done in developing domaindependent benchmark databases for 3D shape searching. We propose a benchmark database for evaluating shape-base...

This paper presents an innovative tool and method that allow efficient innovation of shape and topology of virtual parts at both mesh and CAD levels using optimization methods. The method consists of automatic variations of shapes in CAD/CAE environments that allow effective search for new shapes that are not considered initially by designers.

The paper presents the main characteristics of an innovative platform which has been conceived and designed to extend the operational capabilities of current unmanned surface vehicles in terms of platform stability in waves and of powering requirement at a relatively high speed. The main idea which rules the project is the realization of a small autonomous surface unit (about 6 m in length) cap...

This article gives an overview of the concept of the Visual Hull and what its advantages and disadvantages are. The Visual hull is a concept of a 3D reconstruction by a Shape-From-Silhouette (SFS) technique. This kind of 3D scene reconstruction first has been introduced by Baumgart in his PhD thesis in 1974 [1]. Since then there have been several different variations of the Shape-From-Silhouett...
