This paper explores the use of weighted space syntax models to contribute to the process of integrated urban planning for Jeddah as part of a major planning project in the Saudi Arabia. The Municipality of Jeddah commissioned the production of an integrated suite of planning documents. These plans coordinate Strategic, Sub-Regional, Structural and Local plans across a citywide region and aim to...

Bird flight is an area of significant interest due to the utilization and control of unsteady aerodynamic effects via flapping. Although modern aerodynamics were originally inspired by bird flight, contemporary computational and experimental work associated with flapping flight focuses on insect flight. The purpose of the present paper is to improve the understanding of avian flight by investig...

This paper describes a conngurable design ow management component that supplements a framework by services for online monitoring and control of concurrent design processes. With online monitoring each member of a concurrent working team knows the actual state of every object he wants to manipulate. This avoids unnecessary locking of objects that causes sequentializing of design tasks that could...

Agent models provide a generalised approach to the design of systems that autonomously monitor and affect an environment. Societies of agents which reason and communicate about an environment can achieve complex emergent behaviour to facilitate and augment human activities. This paper introduces artificial agent technologies as a means by which the behavioural complexity of virtual worlds can b...

In this paper it is examined how the relational approach may be used, not only in storing, but also in constructing, tilling in, validating and consulting decision tables. This integration of a decision table system and the relational concept is studied in the context of an existing decision table engineering workbench,PROLOGA (PROcedural LOGic Analyzer), an interactive rule-based design tool f...

A new class of active filters, real active-only filters, is described and possible implementation issues of these filters are discussed. To remedy these issues, a fullydifferential active-only integrator block built around current controlled current conveyors is presented. The integration frequency of the proposed circuit is adjustable over a wide frequency range. As an application, a real acti...

Emergency planning is an ongoing activity in which a multidisciplinary group of experts intermittently collaborate to define the most appropriate response to risks. One of the most important tasks of emergency planning is risk reduction. Such a task compiles the analysis of capabilities to face an emergency, the prioritizing of activities, and the definition of procedures and strategies. It is ...

This paper reports on the prototype design of DisCo, a computer-based design tool that facilitates distributed co-design through Layered Elaboration. Layered Elaboration is a co-design technique that, until now, has relied on paper and clear transparencies to generate ideas through an iterative process in which each version leaves prior ideas intact. The new computer-based system allows co-desi...

In the present article, a specified Pedagogical Infrastructure Framework, including technical, social, epistemological and cognitive components, is introduced as a conceptual tool for design-based research to examine the design of complex learning settings. The applicability of the framework was assessed by retrospectively exploring an evolving design effort in four, consecutive, undergraduate ...
