investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
simulation and design of electronic processing circuit for restaurants e-procurement system
the poor orientation of the restaurants toward the information technology has yet many unsolved issues in regards to the customers. one of these problems which lead the appeal list of later, and have a negative impact on the prestige of the restaurant is the case when the later does not respond on time to the customers’ needs, and which causes their dissatisfaction. this issue is really sensiti...
15 صفحه اولMatching free-form surfaces
In this work, the matching problem between two free-form parametric surfaces, S 0 (u, v) and S 1 (u, v), has been considered in the context of a "rst stage of the metamorphosis process, which is de"ned as gradual and continuous transformation of one key shape into another. A method is presented to approximate the two reparametrization functions, r(u, v) and t(u, v), via a discrete sampled set o...
متن کاملMachining Free-Form Surfaces
This paper presents an analytical method for planning an efficient tool-path in machining free-form surfaces on 3-axis milling machines. This new approach uses a nonconstant offset of the previous tool-path, which guarantees the cutter moving in an unmachined area of the part surface and without redundant machining. The method comprises three steps: (1) the calculation of the tool-path interval...
متن کاملFree-Form Surfaces of degree ( )
This paper introduces new techniques for modeling low degree, smooth freeform surfaces of unrestricted patch layout. In particular, surfaces that are after reparametrization can be built from tensor-product Bézier or spline patches of degree ( ) and (3,d+2); at extraordinary points, these surfaces have the flexibility of splines of total degree . The particular choice, , yields more than vector...
متن کامل3D Free-form Modeling with Variational Surfaces
We describe a free-form stroke-based modeling system where objects are primarily represented by means of variational surfaces. Although similar systems have been described in recent years, our approach achieves both a good performance and reduced surface leak problems by employing a coarse mesh as support for constraint points. The prototype implements an adequate set of modeling operations, “u...
