A Semantics for Shape
Shapely types separate data, represented by lists, from shape, or structure. This separation supports shape polymorphism, where operations are deened for arbitrary shapes, and shapely operations, for which the shape of the result is determined by that of the input, permitting static shape checking. The shapely types are closed under the formation of xpoints, and hence include the usual algebrai...
متن کاملShape Semantics from Shape Context
3D models play an important role in many industrial applications. Therefore semantic processing for the purposes of comparing, cataloging and archiving shapes is a major concern. Most previous work considers comparisons based on the object’s overall geometry or in a reference frame which is computed from the object’s geometry alone, disregarding its context. There are also approaches which prop...
متن کاملGeon-driven shape models for holistic semantics
Cognitive theories of 3D shape decomposition have posited simple volumetric primitives (Geon Structural Description or GSD). In this work, we adapt these Geon models for 3D holistic shape design and present a methodology for evaluating holistic aspects of 3D shape, such as aesthetics, via user-interactive optimisation. The conceptual design space is defined through a set of constraints on the p...
متن کاملOptimal Shape Design for a Cooling Pin Fin Connection Profil
A shape optimization problem of cooling fins for computer parts and integrated circuits is modeled and solved in this paper. The main purpose is to determine the shape of a two-dimensional pin fin, which leads to the maximum amount of removed heat. To do this, the shape optimization problem is defined as maximizing the norm of the Nusselt number distribution at the boundary of the pin fin's con...
متن کاملA 3d Micro-Plane Model for Shape Memory Alloys
are compared with the experimental results. In these test results the shape memory alloys behavior as: super elasticity under various temperatures, loading rate effects, asymmetry in tension and pressure, various loops of loading and unloading, hydrostatic pressure effects, different proportional tension-shear biaxial loading and unloading, and also deviation from normality due to non-proportio...
