This paper reports an observation of communication in collaborative design by examining several historical cases of building design projects. It will present three cases of teamwork in architectural modelling. Each case provides a collection of drawings or illustrations that depict the artefacts being designed and constructed. Looking at the cases from the design as modelling perspective, two i...

In this paper, we examine the demand for fresh water of China in 2025 from the complex system modeling perspective and we develop an efficient, economical and practical water strategy to meet the demand for fresh water in 2025.Different from previous research, this study focus on studying several factors that can influence the demand for fresh water, and their interplay within the complex large...

The "perspective-plane" problem proposed in this paper is similar to the "perspective-n-point (PnP)" or "perspective-n-line (PnL)" problems, yet with broader applications and potentials, since planar scenes are more widely available than control points or lines in practice. We address this problem in the Bayesian framework and propose the "Bayesian perspective-plane (BPP)" algorithm, which can ...

In Computer Science, conceptual modelling and formalization are the basis for developing automated systems, "intelligent" or not. It is often taken for granted that formalization is possible and desirable. In the Language/Action perspective, this assumption has been challenged. The Language/Action perspective promotes "communicative action", in the sense of Habermas, as the building block of in...

One of the problems of systems based on distributed architectures is the communication between applications running on different platforms on a network. The appearance of middleware reduces the complexity in transferring data between heterogeneous platforms of such systems. Up until now, various middleware have been proposed to facilitate the distributed system construction. In the context of c...

This article describes an integrated design of Computer Supported Learning Environments (CSLE) and Workflow Management Systems (WfMS). Fundamental approaches for the integration are pointed out by extending the traditional Build-time modeling perspectives of WfMS. The use of an integrated environment and its synergy effects result in a substantial improvement of the educational level, the day-t...

DIORAMA system which is using rapid information collection and accurate resource tracking can assist incident commanders in their attempt to bring order to the chaos as they direct rescue operations for Mass Casualty Incidents (MCI). This system makes use of active Radio Frequency Identification (RFID) tags to identify the location and status of the patients and responders involved in a MCI. Th...

The concept of “curved perspective” has been used by artists such as M.C. Escher in order effectively convey a sense of three dimensional space while being restricted to a two dimensional canvas. We present an interactive system to create and manipulate projections with a curvilinear perspective. Our system presents the user with a set of intuitive screen-space perspective primitives that contr...

The relationship between supply chain resilience and environmental sustainability (greening) has been a topic of peripheral discussion in the research literature. The aim in this paper is to investigate, from a supply chain modeling perspective, the extent to which supply chain greening and resilience strategies are supportive of each other. A strategic supply chain design model is introduced t...

Studies have shown that random order crossover helps reduces the risk of an out-of-stock event when an order that was issued later arrives earlier to offset the late arrival of an order issued earlier. The current school of thought is that, although such crossovers create complexities from a modeling perspective, they are surprisingly beneficial in practice since they decrease the realized lead...
