Tuesday, June 11, 2002, 10:30 AM - 12:00 PM | Room: 287 SESSION 4    Passive Model Order Reduction    Chair: Jacob K. White - Massachusetts Institute of Tech., Cambridge, MA    Organizers: Jaijeet Roychowdhury, Mustafa Celik    Three excellent papers are presented in this session, with the theme of rigorous approaches to linear passive MOR addressing important theoretical and practical issues.The first paper presents a framework for MOR based on generalized factors that includes popular methods like PRIMA as special cases. The second paper presents a convincing argument that causality is key to effective passive MOR of distributed systems. The final demonstrates that attentiveness to positive real properties ensures passivity in truncated balanced realizations.      4.1 A Factorization-Based Framework for Passivity-Preserving Model Reduction of RLC Systems    Speaker(s): Qing Su - Purdue Univ., West Lafayette, IN    Author(s): Qing Su - Purdue Univ., West Lafayette, IN Venkataramanan Balakrishnan - Purdue Univ., West Lafayette, IN Cheng-Kok Koh - Purdue Univ., West Lafayette, IN      4.2 Model Order Reduction for Strictly Passive and Causal Distributed Systems    Speaker(s): Luca Daniel - Univ. of California, Berkeley, CA    Author(s): Luca Daniel - Univ. of California, Berkeley, CA Joel R.
