Abstract: This project will design next-­‐generation defense mechanisms to protect critical infrastructures, such as power grids, large industrial plants, and water distribution systems. These critical infrastructures are complex primarily due to the integration of cyber and physical components, the presence of high-­‐order behaviors and functions, and an intricate and large interconnection pattern.

Abstract: Buildings in the U.S. contribute to 39% of energy use, consume approximately 70% of the electricity, and account for 39% of CO2 emissions. Hence, developing green building architec- tures is an extremely critical component in energy sustainability. The investigators will develop a unified analytical approach for green building design that comprehensively manages energy sustainability by taking into account the complex interactions between these systems of systems, providing a high degree of security, agility and robust to extreme events.

Abstract: Large-scale critical infrastructure systems, including energy and transportation networks, comprise millions of individual elements (human, software and hardware) whose actions may be inconsequential in isolation but profoundly important in aggregate. The focus of this project is on the coordination of these elements via ubiquitous sensing, communications, computation, and control, with an emphasis on the electric grid.

The objective of this research is to create tools to manage uncertainty in the design and certification process of safety-critical aviation systems. The research focuses on three innovative ideas to support this objective. First, probabilistic techniques will be introduced to specify system-level requirements and bound the performance of dynamical components. These will reduce the design costs associated with complex aviation systems consisting of tightly integrated components produced by many independent engineering organizations.

Abstract: The objective of this project is to develop a distributed algorithmic framework, supported by a highly fault-tolerant software system, for executing critical transmission-level operations of the North American power grid using gigantic volumes of Synchrophasor data.

Abstract:  Understanding failure in protection system using Temporal Causal Diagrams  Situational  awareness  in  large  electrical  systems  and  eventual  fault  source  identification  and  possibly prognostics is a very challenging problem. State of the art relies on a network of protection devices that include relays to detect anomalies and engage circuit breakers to isolate the faulty component(s) in the system.

Abstract: We are at the end of a four­year effort that has dramatically improved the capability of the use of RF sensors, particularly those that measure received signal strength (RSS) to sense the locations and context of people in buildings and homes.  We have investigated both systems which use RFID tags to identify a person or object, and those which use a static deployed network of transceivers for device­free localization, to locate people moving in the environment who do not carry any tag or device.  Locating people who don’t wear a de

Abstract: This project addresses the impact of the integration of renewable intermittent generation and the integration of sophisticated sensing, communication, and actuation capabilities into the grid on the system’s reliability, volatility, and economic efficiency, and seeks to develop system architectures, along with associated optimization and control algorithms to balance such trade-­‐offs. The high level goals of this project can be stated as follows:

Abstract: The objective of this project is to develop a theoretical framework for stochastic learning, decision-making, and control in high-dimensional cyber-physical systems. In our general framework, decision makers dynamically refine their estimates of the time-varying physical system based on acquired information, which may be obtained by distributed sensors.

Abstract: Wireless body area sensing networks (WBANs) have the potential to revolutionize health care in the near term and enhance other application domains including sports, entertainment, military and emergency situations. These WBANs represent a novel cyber-physical system that unites engineering systems, the natural world and human individuals.
