For almost three years, members of the academic, research, and business community in the North Carolina region known as the Research Triangle-the area lying amid the cities of Raleigh, Durham, and Chapel Hill-have been working to create a high-performance regional network. As partners in the North Carolina Network Initiative (NCNI), they have built a network that can serve as a POP handling the multigigabit traffic to be delivered by the next-generation Internet. Thence comes its name: a GigaPOP. Like a great railway junction, the GigaPOP is a central distribution point where huge amounts of digital freight are moved between various end points and the main line (such as the very high-performance Backbone Network Services, or VBNS). The NCNI is one of a handful of regional networking organizations around the country. The others include the California Research and Education Network 2 (Calren2), the Metropolitan REN (MREN) serving the Chicago area, the Houston Area Computational Science Consortium (HACSC), and the New York State Educational and Research Network (Nysernet). NCNI's work, which predates most initiatives for the Internet's second generation, serves as a model of how various regions can latch onto the coming information superhighway to good effect.}, number={2}, journal={IEEE SPECTRUM}, author={Collins, JC and Dunn, J and Emer, P and Johnson, M}, year={1999}, month={Feb}, pages={18–25} } @article{banks_emeric_1998, title={Detection of non-symmetrical damage in smart plate-like structures}, volume={9}, ISSN={["1045-389X"]}, DOI={10.1177/1045389x9800901005}, abstractNote={ A two-dimensional model for in-plane vibrations of a cantilever plate with a nonsymmetrical damage is used in the context of defect identification in materials with piezoelectric ceramic patches bonded to their surface. These patches can act both as actuators and sensors in a selfanalyzing fashion, which is a characteristic of smart materials. A Galerkin method is used to approximate the dynamic response of these structures. The natural frequency shifts due to the damage are estimated numerically and compared to experimental data obtained from tests on cantilever aluminum plate-like structures damaged at different locations with defects of different depths. The damage location and extent are determined by an enhanced least square identification method. Efficacy of the frequency shift based algorithms is demonstrated using experimental data. }, number={10}, journal={JOURNAL OF INTELLIGENT MATERIAL SYSTEMS AND STRUCTURES}, author={Banks, HT and Emeric, PR}, year={1998}, month={Oct}, pages={818–828} } @article{banks_emeric_plancke_1997, title={Modeling of nonsymmetrical damage in plate-like structures}, volume={26}, ISSN={["0895-7177"]}, DOI={10.1016/S0895-7177(97)00131-3}, abstractNote={A two-dimensional model for in-plane vibrations of a damped linear elastic Hookean partially clamped plate-like structure with a nonsymmetrical damage is proposed. The model includes both active and passive contributions of piezoelectric ceramic patches bonded to the surface of the structure. Both strong and weak formulations of the equations of motion are presented. The problem is then formulated as a second-order equation in time. The existence, uniqueness of the solutions, and continuity with respect to the data are discussed.}, number={3}, journal={MATHEMATICAL AND COMPUTER MODELLING}, author={Banks, HT and Emeric, P and Plancke, L}, year={1997}, month={Aug}, pages={55–65} }
