PRECISE Seminar: Overview of GE & GE Research’s "Systems & Synthesis" Lab
October 12, 2016

I will provide an overview of GE, GE Research, and the "Systems & Synthesis" lab. Our  mission is to develop solutions that accelerate systems & sub-systems development & integration through software synthesis, V&V, and large systems discrete event simulation technologies. Our team consists of Controls Engineers, Electrical, & Systems Engineering with a focus on embedded software development & test as well as Formal methods for requirements capture, analysis & design validation & verification. My talk will focus on how we are tying these technologies to…

Joint ESE-PRECISE Seminar: Modeling and Co-design of Control Tasks over Wireless Networking Protocols (State of the Art and Challenges)
September 28, 2016

Wireless networked control systems are the integration of physical processes with wireless networked computing units. The co-design of control policies and network configuration must take into account the joint dynamics of communication protocols/channels and physical devices/processes. In this talk we first give a brief overview of the state-of-the-art on wireless networked control systems. Then we present some recent advances in the co-design of control tasks over wireless networking protocols subject to long term (e.g. failures, malicious attacks) and short term (e.g. dynamic routing,…

PRECISE Seminar: Resilient Monitoring and Control of Distribution Networks
September 21, 2016

This talk will focus on the attacker-defender interactions on electricity distribution networks (DNs) that typically have a tree-like topology. Two attack models will be introduced: (i) manipulation of distributed energy resources by a strategic adversary; and (ii) energy diversion by fraudulent customers. In the first model, the DN operator (defender) responds to the adversary’s action by imposing voltage control and partial load shedding.  This model is used to assess the vulnerability of electricity distribution networks under disruptions of distributed energy resources. In the second…

PRECISE Seminar: Design Automation for Cyber-Physical Systems
September 14, 2016

Cyber-physical systems (CPS) such as autonomous and semi-autonomous vehicles, smart buildings, and industrial automation systems, are poised to bring immense economic and societal benefits. However, the design of these systems faces tremendous challenges from the rapid increase of system scale and heterogeneity, the close interaction with dynamic environment and human activities, the employment of multicore and distributed architectural platforms, and the stringent (and often conflicting) requirements on various design metrics. To address these challenges, it is critical to have a new set…

PRECISE Seminar: Modeling New and Resilient Airspace Operations by Harnessing Open Data in Air Transportation
September 7, 2016

High-fidelity models of airport and airspace capacity enable researchers to study modernization strategies that optimize capacity yet require volumes of detailed aircraft movement data. These datasets exist in the public and private realms but are highly challenging and cumbersome to collect in large quantities. In this talk I will present my real-time data scraping and mathematical modeling methodology to collect and augment real-time trajectory data. Using this data, I present an airport planning study and a study of airspace resiliency. I study the change in terminal area flows due to…
