A major challenge facing system designers is to ensure that a system that has been successfully evaluated in the laboratory will be successfully fielded. Off-nominal testing, in which unexpected conditions are evaluated, is proposed as a method to meet this challenge. Off-nominal testing allows for increased understanding of the humanmachine system under evaluation, may uncover design issues th...

Design documentation is costly, often inconsistent, and generally incomplete. Active Documents offer an active approach to capturing and delivering design rationale. In ADD, an existing implementation of an active document, what is stored and manipulated by system and user is not just information, but knowledge. Delivering knowledge at the interface level is a complex task, involving communicat...

This paper reports on the study of the "underbody front"-automated welding cell at Opel Belgium, a major automobile manufacturer of General Motors International Operations. It employs the use of simulation in an experimental design framework to identify potential improvements in average daily output through management of buffer sizes at key buffer locations within the cell. Many practical appli...

We present AudExpCreator, a GUI-based Matlab tool for designing and creating auditory experiments. AudExpCreator allows users to generate auditory experiments that run on Matlab’s Psychophysics Toolbox without having to write any code; rather, users simply follow instructions in GUIs to specify desired design parameters. The software comprises five auditory study types, including behavioral stu...

Today’s computer aided design systems are based on underlying technologies developed over 20 years ago. Although they have become a key part of the design process, and are ubiquitous in industrial product development processes, they usually come into play after the shape of the design has been created. In essence, today’s CAD systems are used to support design evaluation and analysis, and downs...

Process models play important role in computer aided process engineering. Although the structure of these models are a priori known, model parameters should be estimated based on experiments. The accuracy of the estimated parameters largely depends on the information content of the experimental data presented to the parameter identification algorithm. Optimal experiment design (OED) can maximiz...

New test design techniques should result in better coverage of the input domain and more efficient test cases. In this paper we propose a software-testing model for generating efficient test cases based on the special properties of Design of Experiments (DOE) and Logistic Regression. This model allows the software tester to design and generate efficient test sets. Also the proposed model provid...

Proteins exhibit a wide range of physical and chemical properties, including highly selective molecular recognition and catalysis, and are also key components in biological metabolic, catabolic, and signaling pathways. Given that proteins are well-structured and can now be rapidly synthesized, they are excellent targets for engineering of both molecular structure and biological function. Comput...
