Once every week while school is in session, EECS invites a distinguished researcher or practitioner in a computer science or electrical and computer engineering-related field to present their ideas and/or work. Talks are generally targeted to electrical engineering and computer science graduate students. This colloquium series is free and open to everyone.

Blending engineering and medicine: novel analyses of electrocardiogram for prediction and prevention of sudden cardiac death

Monday, October 28, 2019 - 4:00pm to 4:50pm
Gilfillan Auditorium

Speaker Information

Larisa Tereshchenko
Associate professor of medicine
Knight Cardiovascular Institute

Abstract

Heart disease is the #1 killer in the United States. Sudden cardiac death is a major contributor to cardiovascular mortality and a tragic event for a community and family members. Understanding mechanisms of cardiac arrhythmias is a key factor for further reduction of cardiovascular disease burden and mortality. For initiation of arrhythmia, two components are necessary: trigger and the susceptible electrophysiological substrate. Advances in computer science, digital signal processing, and understanding of cardiac arrhythmia mechanisms led to the development of novel mechanistic electrocardiographic and vectorcardiographic measures. We use a widely available, inexpensive, and non-invasive tool (resting 12-lead ECG) to characterize the electrophysiological substrate of cardiac arrhythmias and sudden cardiac death. Then, we study associations of electrocardiographic phenotype with genomics to understand underlying biology of the electrophysiological substrate. In my talk I will present my translational program, my effort of building Big Data resource (ECGome consortium) and outline opportunities for our collaboration/opportunities for students.

Resilient and Reconfigurable Distribution Systems Using Dynamic Microgrids with Cross-Layer Interdependencies in Cyber and Physical Networks

Monday, November 4, 2019 - 4:00pm to 4:50pm

Abstract

Grid modernization has raised the increasing interests in power system resiliency enhancement. As the penetration level of distributed energy resources (DERs) increases rapidly, a distribution grid, as the active and most significant ‘grid-edge’ for DER integration, plays a crucial role to bridge the grid backbone (i.e., transmission system) to the end-users. A resilient, stable and secure distribution system is urgently needed to modernize electric grids and ensure operation continuity. As an effective entity of integrating DERs and local loads, microgrids have been widely deployed in modern distribution grids. In addition to single and individual microgrids, networked and dynamic microgrids with controllable and effective interconnections have been deployed and studied to advance resiliency enhancement, especially for critical infrastructures. Given the information exchange to ensure stable control and physical interactions between neighboring microgrids, networked and dynamic microgrids can be regarded as coupled cyber and physical systems with interdependencies across layers. In this presentation, a cross-layer and resilient control framework of networked and dynamic microgrids with stability guarantees will be discussed. Particular examples and use cases will also be introduced to verify the proposed control framework.

Abstract

Video compression standards enable applications that we use every day, such as broadcast television, online video streaming, and videoconferencing. A brief tutorial will be presented on the technology used in international video coding standards, including MPEG AVC/H.264, HEVC, and the upcoming VVC. Updates will also be provided on the latest standardization activities to enable immersive media, which enable an immersive experience with 6 degrees of freedom of movement with support for motion parallax.
