Multi-disciplinary virtual prototypes of complex products are increasingly and widely used in modern advanced manufactur- ing. How to effectively address the problems of unified modeling, composition and reuse based on the multi-disciplinary heteroge- neous models has brought great challenges to the modeling and simulation (M&S) science and technology. This paper presents a top-level modeling theory based on the meta modeling framework (M2F) of the COllaborative SIMulation (COSlM) theory of virtual prototyping to solve the problems. Firstly the fundamental prin- ciples of the top-level modeling theory are decribed to expound the premise, assumptions, basic conventions and special require- ments in the description of complex heterogeneous systems. Next the formalized definitions for each factor in top level modeling are proposed and the hierarchical nature of them is illustrated. After demonstrating that they are self-closing, this paper divides the top- level modeling into two views, static structural graph and dynamic behavioral graph. Finally, a case study is discussed to demon- strate the feasibility of the theory. 展开更多

The study addresses the integration of the Building Information Modelling (BIM) methodology with Virtual Reality (VR) and Augmented Reality (AR) technologies in the context of the development of a multidisciplinary project, involving architecture, structures, water network and electrical system components. In order to cover in detail the various design features, the case study was limited to a specific area of a house, the sanitary rooms, as it presents sufficient complexity in modeling and the application of VR and AR software. The VR/AR functionalities applied over the BIM model increase the potential of BIM in the construction sector, contributing to the achievement of a high level of collaboration and control of the project based on an immersive and interactive environment. The elaboration of the different phases of a BIM design requires the transfer of models between BIM and VR/AR systems, allowing us to analyze the main advantages that BIM/VR/AR integration can introduce in the construction industry. The study contributes positively to achieving new knowledge in BIM, being disseminated in an academic research work and illustrated in a practical context. 展开更多

To shed light on the general patterns and trends in urban sprawl research,and to provide reference for future study,bibliometric analysis and refined analysis are conducted for publications in this area from 1991 to 2011.The general publication output,the global geographical distribution of the authors,the funding and institutions involved,the research areas,and the source titles are analyzed and discussed.Scholars in the United States and China have produced most of the documents in urban sprawl and these two countries are also the largest contributors in terms of funding and institutions.′Environmental Sciences&Ecology′,′Urban Studies′,and′Geography′are the most common research areas,and the journal titled Urban Studies has contributed the most articles.Furthermore,the refined analyses on the 500 top-cited and most relevant publications have revealed that research on urban sprawl is closely associated with the categories of′Urban form and development′,′Land use/land development′and′environment/ecology/biology′.Conclusions are made with respect to the basic paradigm of research on urban sprawl.The multi-disciplinary research into urban sprawl are expected to be more diversified and integrated. 展开更多

Immersive virtual product development is a new desi gn , developing and evaluation method of integrated product and processing tragedie s, which using VR, multi-discipline simulation and scientific visualization tec hnologies. Users may have the experiences of being part of a cyberspace environm ent with the ability to navigate and manipulate objects which have properties an d behaviors that correspond to those of the real world objects. We present a fra mework and prototype system of an immerse VPD (IVPD) which enables users to navi gate and interact with 3D peripherals with the display system. The framework of IVPD which we have defined can meet these requirements. In the immersive virtual environment, design will include four main parts: 3D CAD/modeler, multidiscipli ne simulations, CAM and discrete system simulation. 3D CAD/modeler can create 3D geometric objects and import models from other commercial softwares such as UG, CATIA etc. It can also store all kinds of models into databases with hierarchy which will provide geometric models with simulations and evaluations in later pr ocedures. Multidiscipline simulations can integrate many simulations such as FEA , CFD, Noisy and etc. Each kind of these simulation softwares will reflect a cer tain aspect of product or component’s performances. CAM, as a successor of prod uct development, mainly simulates the manufacturing procedures in the computer. Discrete system simulation will able to see the layout problems for a factory. I t is very useful for production management. Participants may actively view the v irtual world revolving around them while others control navigation and simul ations, and may interact with other members such as pass an object from one embo died manikin to another. 展开更多

BACKGROUND Although external penetrating laryngeal trauma is rare in the clinic,such cases often result in a high mortality rate.The early recognition of injury,protection of the airway,one-stage laryngeal reconstruction with miniplates and interdisciplinary cooperation are important in the treatment of such patients.CASE SUMMARY A 58-year-old male worker sustained a penetrating injury in the left neck.After computed tomography scanning at a local hospital,he was transferred to our hospital,where he underwent tracheotomy,neck exploration,extraction of the foreign object,debridement and repair of the thyroid cartilage using titanium miniplates.An endo laryngeal stent was inserted,which was removed 12 days later.The patient recovered well and his voice rapidly improved after surgery.CONCLUSION Penetrating laryngeal trauma is uncommon.We successfully treated a patient with early laryngeal reconstruction and management by interdisciplinary cooperation. 展开更多

This paper discusses the present state of Tra- ditional Chinese Medicine being divided into three leading lines of thought, namely, the Clinical line, the Integration of Western and Chinese Medicine line and the Development of Traditional Chinese Medicine line. It also describes the position of Tra- ditional Chinese Medicine being a medical science rich in philosophy and wisdom and a culture centred upon medical science and technology. It outlines the basic characteristic of Traditional Chinese Medicine being rooted in the ’ Holistic Theory’ and ’ Syndrome Differentiation and Treatment ’ and pointed out various flaws in methodology in Integra- tion of Western and Chinese Medicine research. It also stresses that in order to make fruitful progress in the development of Traditional Chinese Medicine, multi-discipline research in Traditional Chinese Medicine should be made on a thoroughly under- standing of the basic methodology of Traditional Chi- nese Medicine and follow its established principles. 展开更多
