an investigation of Design Requirement volatility risk and priority in early stage Design projects
ASME 2015 International Design Engineering Technical Conferences and Computers and Information in Engineering Conference, 2015Co-Authors: Qifang Bao, Francisco Morocz, Sami El Ferik, Mian Mobeen Shaukat, Maria C YangAbstract:In new product development, Design Requirements are a formalization of a product vision and can evolve substantially in the early stages of product Design. This paper describes an empirical study of the relationships among Design Requirements volatility, risk, prioritization and the quality of Design outcome in the context of a graduate level product development course for mid-career professionals. Among other findings, a pattern of decreasing risk of a Design Requirement, especially the risk of high priority Requirements, was found to be a key predictor of success. The findings suggest the importance of managing Design Requirement risk in early stage Design and the potential benefit of using risk and priority level of Design Requirements to monitor Design project health.Copyright © 2015 by ASME

Design Requirement of a renewable energy plus compressed air energy storage and regeneration system
ASME 2015 34th International Conference on Ocean Offshore and Arctic Engineering, 2015Co-Authors: Tim Finnigan, Dominique RoddierAbstract:There are potential offshore applications where renewable energy and more distributed power sources could supplement or replace costly equipment upgrades for additional power supply, or costly fuel operating costs. Renewable energy technologies can also be employed in lieu of expensive power umbilicals to provide power to subsea pumps for long distance tiebacks in deepwater. For example, power umbilicals alone required to provide 69kV to subsea pumps in deepwater could be upwards of $300MM for 100 mile long distance tie-backs. A renewable energy source, with storage, integrated into that system could significantly reduce both the CAPEX and OPEX costs.In 2013, Chevron performed an in-depth evaluation of a Renewable Energy plus Compressed Air Energy Storage and Regeneration system for a 2.6MW application. For the purpose of that study, a floating wind turbine in 365m water depth off the coast of Oregon was evaluated as the energy source as the base case. The system was found to be feasible with initial CAPEX costs replaced within 12 years of operations as compared to installation of a diesel power generation system and the requisite fuel required to run the equipment.This paper provides a description of the OCAES system, and discusses potential applications in support of the offshore oil and gas industry.Copyright © 2015 by ASME

test research on the effects of mechanochemically activated iron tailings on the compressive strength of concrete
Construction and Building Materials, 2016Co-Authors: Yunhong Cheng, Fei Huang, Wenchuan Li, Guanglu LiAbstract:Abstract High-silicon iron tailings, which have been mechanochemically activated, was used for the preparation of concrete as a supplementary cementing material to substitute cement (by 10%, 20%, 30% and 40% respectively) based on their composition, particle sizes and pozzolanic activity. With the aid of tests, this paper discusses the effects of the tailings on the compressive strength of concrete. Tests show that with an increase in substitution rate of cement in the tailings, the compressive strength of concrete tends to decrease, and when the substitution rate is at 10%, 20% and 30% respectively, the compressive strength of concrete is measured up to the Design Requirement; if an appropriate amount of water reducing admixture is added while cement is substituted by tailings with a substitution rate of 10%, 20%, 30% and 40% respectively, the compressive strength of concrete is also measured up to the Design Requirement. The research result demonstrates that as far as the compressive strength concerned, it is feasible to use mechanochemically activated high-silicon iron tailings as a supplementary cementing material to partly substitute cement in concrete.

the user s touch a Design Requirement for smart spaces
Ubiquitous Computing, 2009Co-Authors: Fernando Martinez Reyes, Chris GreenhalghAbstract:The home of the future will be able to offer comfortable, safe and supportive home spaces. Smart systems and artefacts will know users' routines and anticipate their needs. While the vision of the home of the future is promissory, it is the user who supports UbiComp systems, but certain technical and social challenges must be addressed before the smart home can become a reality. Unexpected human behavior makes it difficult to identify and predict domestic activity. Thus, if a system is not reliable or trusted enough to take actions on behalf of users, context-aware Designs must allow for user participation to support the systems' performance. In this article, the authors use their experience Designing a context-aware system to illustrate how the users' "touch", that is, their active involvement, is still a Requirement for today's UbiComp Designs. The configurable system described supports parents awareness of their children's activity. Responses from a user study indicate that parents engaged positively with this kind of mediated, rather than proactive, computing-based support.
