This paper introduces a design tool that provides customised engineering analysis functionalities for a manufacturer of metal frames. This work is motivated by the need for supporting small to medium scale enterprises (SMEs) with affordable computer aided analysis tools. The design process followed by a SME, Wright Metal Products of Simpsonville, SC, primarily depends on special expertise of a ...

People buy products to express their desired identity and therefore prefer products that fit their own personality. The personality of products is created by implicit and explicit design features. However the translation of implicit and explicit design characteristics into new designs is difficult for designers. Especially for beginning design students, giving meaning to products by thinking ab...

The purpose of this research was to develop an approach to artifact design based on information technology. To make interactive systems easy to use, many companies utilize a user centered design approach. One of the principles for user centered design is to consider the total user experience to cover all of the user’s views. To consider the total user experience is not easy because a user’s exp...

We present a workbench for database design which supports designers eeciently and informally to achieve correct and eecient databases.

Integrating analytic tools within a production Computer Aided Design (CAD) environment provides designers the opportunity to evaluate the impact of design decisions much earlier in the design process than previously possible. Softdesk Energy is a design tool that integrates building energy analysis capabilities into a highly automated production drafting environment (AutoCAD and Softdesk AutoAr...

One of the evolving topics in design research is the study of experience as a source of inspiration for the design of more enjoyable user-product interactions. An issue that escapes these studies is the way in which human experience and a product’s contextual information trigger users’ understanding of a product’s use. This paper introduces research that investigates how people’s experience inf...

We present a constructive stabilization algorithm for a particular class of driftless control aane systems. The algorithm makes systematic use of homogeneity, Lie brackets of vectorrelds and Lie algebraic properties , and the resulting feedback laws are periodically time-varying.

In this paper we propose anti surge controllers for a close coupled valve in a compression system. The valve modifies the characteristic of the compressor, and allows for stable operation beyond the original surge line. The design tool used is backstepping and global uniform asymptotic stability is proven. Damping terms are included in the controllers, and in the presence of both mass flow and ...
