Probabilistic system-reliability methods have the potential to assist designers in better understanding the ultimate global behavior of bridges, thus leading to more economical, rational, and reliable structures. Nonetheless, these techniques are not currently broadly used in North American bridge engineering practice. Using a sample cable-stayed bridge design, a study is conducted to assess th...

A rapid yield estimation methodology that aids the analog circuit designer in making design trade-offs that improve yield is presented. This methodology is based on using hierarchical evaluation of analysis equations, rather than simulation, to predict circuit performance. The new analog rapid yield estimation (ARYE) method has been used to predict the yield of two-stage op amps, and has been i...

The user’s experience of his or her interaction with a product is becoming an increasingly important aspect of product design. In the ‘experience economy’, experiential factors have become major discriminants affecting the success of new products. Industry is well aware of this, and likewise design schools are adjusting their curricula to better train their students to take into account factors...

As the aesthetic aspect of a product is becoming more and more important in customers' decisions, there is an increasing need of tools able to express and preserve the styling intent during the product development cycle, while offering an interaction with the user much more adherent to his mentality. The European Project FIORES-II (Character Preservation and Modelling in Aesthetic and Engineeri...

  In this paper, authors tackle three very important questions that need to be answered if a theory of design is to be constructed. The first is what designers do, Which we attempt to illustrate with the help of case studies and theories of design practice. The second question is what guides designers. Here, authors try to present some of the proposed normative positions about design, to show t...

This paper describes our approach for the design and development of application systems for early stages of information design tasks. We view a computational tool as something that provides materials with which a designer interacts to create a situation that talks back to the designer. The interaction design of a tool, that is, the representations a user can generate and how the user can manipu...

User frustration research has been one way of looking into clinicians' experience with health information technology use and interaction. In order to understand how clinician frustration with Health Information Technology (HIT) use occurs, there is the need to explore Human-Computer Interaction (HCI) literature that addresses both frustration and HIT use. In the past three decades, HCI frustrat...
