Talk Title: Future Power System Control Functions: An Industry Perspective
Abstract: This talk provides an overview of Siemens Corporate Technology's recent research on new control functions for future power systems. Three different topics are discussed: (a) adaptive power oscillation damping optimization to increase the stability reserve of power systems, (b) robust power flow optimization to increase power system resilience to volatile generation, and (c) autonomous microgrids that provide autonomous operation and plug-and-produce capabilities.
Biography: Ulrich Muenz is head of the Research Group Autonomous Systems and Control at Siemens Corporate Technology in Princeton, NJ. Prior to this appointment, he was a senior key expert research scientist for power system stability and control at Siemens Corporate Technology in Munich, Germany. He received his Ph.D. degree in Automatic Control from the University of Stuttgart, Germany in 2010, and MSc degrees in Electrical Engineering and Telecommunications from the Universities of Stuttgart, Germany, and Madrid, Spain, both in 2005. He received the EECI European Ph.D. Award on Embedded and Networked Control in 2010. From 2010 to 2011, he was a systems engineer at Robert Bosch GmbH. His main research interests are autonomy technologies based on model- and data-driven methods for applications like power systems and industrial manufacturing.

Quantitative susceptibility mapping (QSM): tissue magnetism, mathematical optimization and clinical applications

Talk Title: Quantitative susceptibility mapping (QSM): tissue magnetism, mathematical optimization and clinical applications
Series: Biomedical Engineering Seminar
Abstract: Tissue magnetism refers to the electron-“proton interaction, which is long range with its effects on MRI being treated as static dephasing. In contrast, tissue relaxation refers to the proton-“proton (commonly known as spin-spin) interaction, which is short range with its effect on MRI being treated with nonequilibrium quantum statistical mechanics. The long-range magnetism implies nonlocal blooming artifacts in both T2* hypointensity and phase of MRI signal. Quantitative susceptibility mapping (QSM) is to deconvolve blooming artifacts, using the Bayesian approach to the magnetic field to susceptibility source inverse problem. QSM has become sufficiently accurate and robust for routine applications. QSM is advancing MRI of tissue magnetic susceptibility from simple qualitative detection of hypointense blooming artifacts to precise measurement of biodistributions. Tissue susceptibility contains rich functional and structural information pertinent to molecular electron cloud properties. The dominant susceptibility sources in tissue are biometals, which are vital participants in cellular functions and pathologies. QSM can be useful for diseases that involve neurodegeneration, inflammation, hemorrhage, abnormal oxygen consumption, substantial alterations in highly paramagnetic cellular iron, bone mineralization, or pathologic calcification; and for all disorders in which MRI diagnosis or surveillance requires contrast agent injection. Clinicians should consider integrating QSM into their routine imaging practices by including gradient echo sequences in all relevant MRI protocols.
