In this paper we discuss our development of the Emotion Sampling Device (ESD). We introduce the major properties of the device and advocate the need for a tool that can be effectively incorporated into product development lifecycles to inform the usability evaluation process as well as other areas of product design. As well as providing an insight into the properties of the ESD and to what exte...

In the engineering, Simulation Based Design (SBD) has been generalizing. This paper proposes a new Web communication form of knowledge-based contents for collaborative Virtual Engineering in worldwide Distributed Engineering Environment (DEE). This paper describes the architecture and example demonstrations of Web-based World Wide Simulation Environment (WISE) using engineering information and ...

Abstract: Nowadays, the requirements of customers concerning a product are more and more tight and high. The satisfaction of these, such as quality, reliability, robustness and cost, plays an important role in the context of global and concurrent economy. However, a product, during its life cycle, passes through manufacturing and assembly stages where geometrical deviations are generated and ac...

viii decisions towards sustainability. Closed loop Lifecycle Management contains four main components, PEIDs’ for collecting data, middle ware to combine different applications and collect and distribute life cycle data, a decision support system (DSS) to transform the collected data into usable information and a product knowledge and management sys tem (PDKM) to manage the information and know...

Business to business cooperation is undergoing large changes, resulting in new requirements on how to develop products, and thereby forcing companies to optimize their part of the total product system. Aerospace business agreements are being made on a life cycle basis where the actual product ownership often remains with the manufacturer. Revenue for aero engine manufacturers and their engine p...

in this paper, we investigate a problem of finding natural condition to assure the product of two graphs to be hamilton-connected. we present some sufficient and necessary conditions for $gbox h$ being hamilton-connected when $g$ is a hamilton-connected graph and $h$ is a tree or $g$ is a hamiltonian graph and $h$ is $k_2$.
