SUMMARY:Space Domain Awareness in the Artemis Era
DESCRIPTION:Since the Apollo era\, space has become an increasingly valuable domain for national security due to diplomatic\, informational\, and economic reasons. The last few years have seen exponential growth in the launch of space objects and there is an increased interest in having a permanent cislunar presence through the Artemis program. The understanding of motion of a spacecraft in multi-body environment is essential to transit between different regions in the cislunar space and to forecast and track objects in the cislunar space. The perturbed two-body restrictive framework has led to extensive modeling\, analysis\, and analytical solutions to study spacecraft motion in orbits around the Earth. However\, beyond GEO (XGEO) the dynamical environment shifts\, and the structure of fundamental behaviors can be radically different. The primary challenge that limits the transferability of tools and techniques from the GEO to XGEO region is non-Keplerian dynamics\, data sparsity from limited coverage and availability of sensors. The process of orbit determination and forecasting the path for an object based on short time arc observations is not trivial. This talk will introduce novel tools to track spacecraft motion in cislunar space and transfers between different regions in cislunar space. These tools make use of dynamical system theory in combination with advances in optimal control theory to provide a better understanding of transport mechanisms in cislunar space. Local orbit elements will be discussed to characterize the trajectories in the cislunar space.\n\nSpeaker : Dr. Puneet Singla\n\nBiography:\n\nDr. Puneet Singla is a Harry and Arlene Schell Professor of the Aerospace engineering at the Pennsylvania State University (PSU). Dr. Singla’s research focus pertains to uncertainty propagation through nonlinear systems\, data driven modelling and control of autonomous systems. His research related honours include the IEEE AESS’s Judith A. Resnik Award\, NSF CAREER award\, the AFOSR Young Investigator award\, the University at Buffalo’s “Exceptional Scholar” Young Investigator Award and the Texas A&M University’s Young Aerospace Engineering Distinguished Alumni Award in recognition of his scholarly activities. He is a fellow of American Astronautical Society (AAS) and an associate fellow of American Institute of Aeronautics and Astronautics (AIAA).

SUMMARY:Nature of Phase Kinetics and Memory in Shape Memory Alloys
DESCRIPTION:Shape Memory phenomenon in some intermetallics like NiTi is well known. However\, during arbitrary thermomechanical loading\, these materials exhibit several other interesting\, yet less-understood phenomena. In this talk\, Thermal Arrest Memory and associated effects during interrupted phase transformations in shape memory alloys are discussed and some fascinating underpinnings in the associated martensitic transformations are highlighted.\nThe research talk will be followed by a presentation by the speaker about potential Research and Teaching initiatives and future directions toward collaborative activities at the department. This will include a brief overview of the R&D experience of the speaker over 3 decades\, and a strategy to pursue Research and Development of allied Aerospace technologies and engage with relevant organizations. A brief overview of proposed elective courses like Advanced Aerospace Materials\, and Life-Cycle Analysis and Design of Aerospace systems and components is provided. These are aimed at enhancing the academic level of the students of the department and making them more contemporary. \nSpeaker : Dr. Vidyashankar Buravalla \nBiography :  \nDr. Vidyashankar Buravalla obtained his Ph.D in Aerospace Engineering from IISc in 1998. He has worked in National\, International\, and Multinational R&D entities over the last 3 decades. His areas of expertise include Smart materials and systems\, composite materials and structures\, continuum mechanics\, thermodynamics\, fracture mechanics\, vibration and damping\, NDE and turbomachinery.  He recently superannuated as a Principal Engineer from GE Global Research Center in Bangalore where he worked for nearly 13 years. Prior to that\, he worked in GM R&D for nearly 10 years\, in ADA for 3 years\, and in Rolls-Royce Technology Center in Sheffield UK for 3 years as a Research Fellow. He has 24 Journal and 13 Conference publications and more than 35 technical internal reports. He has 15 patents awarded and more than 30 patent applications under review/processing. He has received several awards in his R&D career and also served as an Adjunct Faculty at IIT-Kanpur between 2008 and 2012. He is associated with several professional bodies and recently served as Hon. President of the Institute of Smart Structures and Systems (ISSS).
