A new Lectureship Series has been endowed by Professor Richard Partch and his wife JoAnne, in recognition of Professor Egon Matijevic'’s outstanding accomplishments over the past 50 years. In particular, it is in honor of Egon’s teaching and research with students and of his internationally recognized achievements in colloid and surface chemistry for over five decades. A major goal of this Series is to focus audience attention on the powerful impact that a Clarkson education can have on its graduates.
Professor Terry Ring (a Clarkson alumnus) had the honor of presenting the inaugural Egon Matijevic' Endowed Lectureship at Clarkson University on October 1, 2010. He earned two degrees from Clarkson College of Technology (Clarkson University’s former name): a B.S. in Chemical Engineering in 1972 and a M.S. in Physical Chemistry in 1977. Professor Ring’s lecture described how a Clarkson education enhanced his successful international career. He previously served as an Honorary Visiting Professor at Tsinghua University in China (2004-2007), a Visiting Professor for the Swiss Federal Institute of Technology (1999), a Visiting Professor for the Science University Tokyo (1994), and as a Professor Honoraire for the Swiss Federal Institute of Technology (1993). Dr. Terry Ring is currently Professor and former Chair of Chemical and Fuels Engineering at the University of Utah. He is also Chairman of the Board of Directors of the Council for Chemical Research of the American Chemical Society; the interface between the industry, the society, and the nation.
Professor Ratneshwar Jha has conducted research in structural health monitoring, modeling of composite and smart structures, adaptive control of structural vibrations, intelligent flight controls, and multidisciplinary design optimization. He has established the Smart Structures Laboratory at Clarkson University which is well equipped for vibration measurement and control experiments, including a scanning laser vibrometer. Dr. Jha’s contributions include both theoretical and experimental research which have resulted in over 70 publications in international archival journals and refereed conference papers. He is a member of the Editorial Board for the International Journal of Aerospace Engineering, an Associate Fellow of the American Institute of Aeronautics and Astronautics, and a member of ASME and ASEE. Dr. Jha is also a member of the AIAA Adaptive Structures Technical Committee and has served as Session Chair/Co-Chair for Adaptive Structures Conferences. He was awarded a Graham Faculty Research Award by Clarkson University in 2005. Dr. Jha has received research grants from the National Science Foundation, AFOSR, NASA, the US Army, the New York State Energy Research and Development Authority and from several industries. Prior to joining Clarkson, Dr. Jha worked in the aerospace industry from 1983 to 1995 where he led a team of engineers working on conceptual and preliminary designs of combat aircraft.
Development of Higher-Order Spectra for Structural Health Monitoring and System ID of Composite Structures and Flexible Thin Films
Higher order spectral analysis techniques are often used to identify nonlinear interactions in modes of complex dynamical systems. The bi-spectrum and tri-spectrum have proven to be useful tools in testing for the presence of quadratic and cubic nonlinearities based on a system’s stationary response. Professor Pier Marzocca is carrying out structural health monitoring and system ID research in collaboration with the Naval Research Laboratory in Washington DC and the University of Rome La Sapienza. His studies involve numerical and experimental investigations to identify the presence and extent of nonlinear interactions between frequency components and to understand how modes interact nonlinearly producing intermodulation components at the sum and/or difference frequency of the fundamental modes of oscillation. New identification tools have been proposed. Novel reliability simulator tools for thin film PV and turbine blades and other flexible structures are also under development. They can be used as a benchmark for validation of nonlinear analysis methods associated with structural health monitoring techniques and to evaluate performance, reliability, durability, and lifetime characteristics of these systems.
Professor Pier Marzocca has expertise on the structural dynamics and control of advanced aerospace systems, including active flow and aeroelastic controls of flexible structures and unmanned aerial vehicle systems. He leads or co-leads research projects that have totaled more than $4 million in funding from governmental agencies, private foundations, and industry. His recent projects involve the development of novel wind turbine systems, modeling and design of functionally graded structures, energy harvesting, development of computational aeroelastic and aerodynamic tools, reliability of complex industrial systems and components including gas turbine engines and flexible thin films for solar cell applications, and unmanned aerial vehicle systems. In addition, he has been working on structural health monitoring and damage detection in structural systems.
