Ontologies And Shape Grammars: Communication Between Knowledge-Based And Generative Systems, Francois Grobler, Ajla Aksamija, Hyunjoo Kim, Ramesh Krishnmurti, Kui Yue, Casey Hickerson

Ajla Aksamija

This paper discusses information flow between knowledge-based models and shape grammars for generation of building designs, explaining the interaction, system and implementation. The benefit for using the interactive system is that the complementary properties of the two schemes are used to strengthen the overall process. Shape grammar contains rules about the geometric organization, while knowledge-based model supports the contextual information.

Information Technology And Architectural Practice: Knowledge Modeling Approach And Bim, Ajla Aksamija, Mir Ali

Ajla Aksamija

This paper presents recent developments in information technologies and their impact on architectural design. It presents a practical technique for knowledge-based information modeling extending the currently prevailing Building Information Modelling (BIM) to include information beyond the building elements, and to foster analysis during the design process. Interactive web-based application for information discovery and design analysis is discussed as a case study. The application integrates several aspects of the early schematic design, and is intended for demonstration of integrated design factors.

Cascading Infrastructure Failures: Avoidance And Response, George H. Baker, Cheryl J. Elliott

George H Baker

No critical infrastructure is self-sufficient. The complexity inherent in the interdependent nature of infrastructure systems complicates planning and preparedness for system failures. Recent wide-scale disruption of infrastructure on the Gulf Coast due to weather, and in the Northeast due to electric power network failures, dramatically illustrate the problems associated with mitigating cascading effects and responding to cascading infrastructure failures once they have occurred.

The major challenge associated with preparedness for cascading failures is that they transcend system, corporate, and political boundaries and necessitate coordination among multiple, disparate experts and authorities. This symposium brought together concerned communities including government and industry …
