Abstract: As customer preference is viewed as a reflection of desires for product features and even future product opportunities, it is crucial for the generation of design concepts. In this paper, a six-stage methodology is described for...
Abstract: The issue of environmental sustainability, which is unprecedented in both magnitude and complexity, presents one of the biggest challenges faced bymodern society. Design engineers can make significant contributions by...
Abstract: Analysis of mesh models is gaining prominence as it has wide range of applications from engineering to medicine. In this paper, we present a method for analyzing meshes through the abstraction of its prominent cross-sections (PCS). An...
Abstract: The cost and environmental impacts of a product are largely determined during conceptual design. Most often, due to cost and time limitations, only a limited set of design concepts are carried forward for detailed design. As a result,...
Abstract: Reducing the environmental effects of products has become a significant focus of corporate strategies. As a result, easy-to-use ecodesign tools thatcan be implemented during the early design stage are essential for...
Abstract: Customers often show different preferences relative to the same products, such as function, shape, color, costs, etc. They will surely affect product market activities further. In this paper, a model of preference elicitation from...
Abstract: 3D shape retrieval and clustering is of current interest in several different fields, including mechanical engineering. Several new shape representations for 3D objects are continuing to emerge. Most shape representations are embedded in...
Abstract: The issue of environmental sustainability, which is unprecedented in both magnitude and complexity, presents one of the biggest challenges faced by modern society. Engineers, including mechanical engineers, can make significant...
Abstract A global visibility map is a spherical image built to describe the complete set of global visible view directions for a surface. In this paper, we consider the computation of global visibility maps for regions on the boundary of a...
Abstract: Background: Techniques for inferring the functions of the protein by comparing their shape similarity have been receiving a lot of attention. Proteins are functional units and their shape flexibility occupies an essential role in...
Abstract: When existing parts are re-used for the development of a new product or business-to-business transactions, a method for searching parts from a part database that is similar to the user’s requirements is necessary. To this end, it...
Abstract: The modularity indicates a one-to-one mapping between functional concepts and physical components. It can allow us to generate more product varietiesat lower costs. Functional concepts can be described by precise syntactic...
Abstract: The potential advantages of freehand sketches have been widely recognized and exploited in many fields especially in engineering design and analysis. This is mainly because the freehand sketches are an efficient and natural way...
Abstract: Wikis, freely editable collections of web pages, exhibit potential for a flexible documentation and communication tool for collaborative design tasks as well as support for team design thinking early in the design process. The...
Abstract: The use of design notebooks has long been common practice for engineers and designers. Wikis, freely editable collections of web sites, are becoming increasingly popular as flexible documentation and communication tools for collaborative...
Abstract: Background: The conventional superposition methods use an ordinary least squares (LS) fit for structural comparison of two different conformations of the same protein. The main problem of the LS fit that it is sensitive to outliers,...
Abstract: Background: Many molecules of interest are flexible and undergo significant shape deformation as part of their function, but most existing methods of molecular shape comparison (MSC) treat them as rigid bodies, which may lead to...
Abstract: Beautification of freehand sketches is integral for building robust sketch understanding systems and sketch-based inter-faces for CAD. Many of the current methods for beautification do not consider some important information implied in...
Abstract:A robust technique for determining the principal axes of a 3D shape represented by a point set, possibly with noise, is presented. We use techniques from robust statistics to guide the classical principal component analysis (PCA)...
Abstract: When engineering content is created and applied during the product life cycle, it is often stored and forgotten. Current information retrieval approaches based on statistical methods and keyword matching are not effective in understanding...
