Redesigning the design process through interactive simulation: A case study of life-cycle engineering in jet engine conceptual design

Many aerospace companies are currently making the transition to providing fully-integrated product-service offerings in which their products are designed from the outset with life-cycle considerations in mind. Based on a case study at Rolls-Royce, Civil Aerospace, this paper demonstrates how an interactive approach to process simulation can be used to support the redesign of existing design processes in order to incorporate life-cycle engineering (LCE) considerations. The case study provides insights into the problems of redesigning the conceptual stages of a complex, concurrent engineering design process and the practical value of process simulation as a tool to support the specification of process changes in the context of engineering design. The paper also illustrates how development of a simulation model can provide significant benefit to companies through the understanding of process behaviour that is gained through validating the behaviour of the model using different design and iteration scenarios.This research was co-funded by the Technology Strategy Board’s Collaborative Research and Development programme (www.innovateuk.org), reference TP/2/IC/6/I/10292, and the IMRC Block Grant. We are also indebted to Dr. Michael Moss and all the other personnel within Rolls-Royce who supported this research.Post-prin

RIACS

The Research Institute for Advanced Computer Science (RIACS) was established by the Universities Space Research Association (USRA) at the NASA Ames Research Center (ARC) on June 6, 1983. RIACS is privately operated by USRA, a consortium of universities that serves as a bridge between NASA and the academic community. Under a five-year co-operative agreement with NASA, research at RIACS is focused on areas that are strategically enabling to the Ames Research Center's role as NASA's Center of Excellence for Information Technology. The primary mission of RIACS is charted to carry out research and development in computer science. This work is devoted in the main to tasks that are strategically enabling with respect to NASA's bold mission in space exploration and aeronautics. There are three foci for this work: (1) Automated Reasoning. (2) Human-Centered Computing. and (3) High Performance Computing and Networking. RIACS has the additional goal of broadening the base of researcher in these areas of importance to the nation's space and aeronautics enterprises. Through its visiting scientist program, RIACS facilitates the participation of university-based researchers, including both faculty and students, in the research activities of NASA and RIACS. RIACS researchers work in close collaboration with NASA computer scientists on projects such as the Remote Agent Experiment on Deep Space One mission, and Super-Resolution Surface Modeling

Research on real-time physics-based deformation for haptic-enabled medical simulation

This study developed a multiple effective visuo-haptic surgical engine to handle a variety of surgical manipulations in real-time. Soft tissue models are based on biomechanical experiment and continuum mechanics for greater accuracy. Such models will increase the realism of future training systems and the VR/AR/MR implementations for the operating room

Alternative energy design toolkit

Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2004.Includes bibliographical references (p. 122-127).This thesis concerns the concepts, structure, and applications of the Alternative Energy Design Toolkit. The toolkit is aimed to provide a widely accessible, easy to use, flexible, yet powerful modeling environment for assisting design associated with renewable energy technologies. Exchanges of ideas and knowledge among the users are also highly encouraged and facilitated. The toolkit is composed of three important components: a collection of models that are fundamentals of renewable energy design, a modeling environment called DOME, which is used as the toolkit's enabler, and a supporting Web site. At the beginning, a comprehensive survey of existing tools for renewable energy design is presented. Then, the detailed descriptions and key capabilities of the toolkit's components are provided. In addition, a collection of solar energy models, which is the initial set of models in the toolkit, is also presented. The toolkit is utilized in two design scenarios: a design of a stand-alone PV system, and a trade-off analysis of a hybrid PV-diesel electricity system. In both design scenarios, the models in the toolkit are proven to be useful and convenient resources. The processes of making the representations of the systems are straight-forward, and the analysis mechanisms that the toolkit provides make the design process simple yet effective.by Sittha Sukkasi.S.M

The 1998 Center for Simulation of Dynamic Response in Materials Annual Technical Report

Introduction: This annual report describes research accomplishments for FY 98 of the Center for Simulation of Dynamic Response of Materials. The Center is constructing a virtual shock physics facility in which the full three dimensional response of a variety of target materials can be computed for a wide range of compressive, tensional, and shear loadings, including those produced by detonation of energetic materials. The goals are to facilitate computation of a variety of experiments in which strong shock and detonation waves are made to impinge on targets consisting of various combinations of materials, compute the subsequent dynamic response of the target materials, and validate these computations against experimental data

The utilisation of games technology for environmental design education

In recent years, the architectural design process has witnessed a mounting demand for qualified practitioners who can resolve the highly complex social, cultural, technological, and economical issues associated with ‘Sustainability’. Designers are thus faced with wider pallet of challenges, developing conceptual designs that are sustainably effective. Pressure is mounting on educational institutions to prepare architects that are well accustomed to the environmental design concepts and parameters, aiming to reduce the impact on the environment and preserve valuable natural resources to bring the building’s interior to comfortable living conditions. However, architectural education has been notably slow to respond effectively to the requirements introduced by sustainability. Evidently there are a number of pedagogical challenges that clearly impede the consistent endorsement of sustainability in the design curricula and thus hinder any potential values and opportunities that can result from its effective integration. This research project examines these challenges and investigates more into their nature and attributes. Accordingly, it proposes a method that endeavours to overcome the noted challenge and attempts to improve the design students' motivation and acceptance to incorporate sustainability. In essence, this method aims to mould the technical nature of Building Performance Simulation applications into the cognitive design process. In order to achieve this, the proposed method utilizes 3D games technology, incorporating Multi-Agent System and Data Mining techniques, to assist design students in achieving higher levels of motivation, engagement, and comprehension of the environmental design concepts. The research discusses the rationale for electing the employed technologies and discusses the methodology for developing the proposed tool. Following its development, the tool is presented to number of stakeholders for evaluating the pedagogical and conceptual basis. The recorded results and the provided feedback from these sessions are presented to assess the potential effectiveness of this method for improving students' understanding of various concepts surrounding sustainable design
