Abstract: The tight integration of physical and information processes in CPS necessitates the development of a new systems science, which is simultaneously computational and physical. Dynamics, modeling, feedback, and control are central issues in CPS research. The unique challenges in CPS integration emerge from the heterogeneity of components and interactions.

Abstract: Analytically predicting the behavior of physical systems is generally not possible. For example, the three dimensional nature of physical systems makes it provably impossible to express closed-­‐form analytical solutions even simple systems. This limitation makes experimentation the primary modality for designing new cyber-­‐physical systems.

Abstract: Electrification of the transportation market offers revenue growth for utility companies and automobile manufacturers, lower operational costs for consumers, and benefits to the environment. However, even moderate penetration of PEVs will stress the power grid. This project formulates and solves optimization problems critical to various entities in the PEV ecosystem -- PEV owners, commercial charging station owners, aggregators, and distribution companies -- at the distribution / retail level.

Abstract: This study attempts to address a range of problems associated with autonomous navigation in real‐life urban traffic, most recently including controller design and safety, secure communication, mapping, pedestrian behavior, testing and intersection access.

Abstract: The principal objective of this project is the development of novel control architectures and computationally efficient controller design algorithms for distributed cyber-­‐physical systems with decentralized information infrastructures and limited communication capabilities. We are interested in distributed cyber-­‐ physical systems where the system components are able to communicate with one another. Cooperative active safety in Intelligent Transportation Systems is our focus cyber-­‐physical application.

Abstract: The objective of this inter-disciplinary research is to develop new wireless technologies that transform the streets of a city into a hybrid transportation/communication system, called the Intelligent Road (iRoad), where autonomous wireless devices are co-located with traffic signals, forming a wireless network that fuses transportation data from all over the city to support a wide range of new applications.

Abstract: Advanced autonomous transportation technologies must become robust, affordable and maintainable before safe and wide public adoption. The following research challenges of cyber-physical systems must be overcome before autonomous vehicles become practical:

Abstract: The objective of the project is to demonstrate the synergistic use of a cyber-physical infrastructure consisting of smart-phone devices; cloud computing, wireless communication, and intelligent transportation systems to manage vehicles in the complex urban network – through the use of traffic controls, route advisories and road pricing – to jointly optimize drivers’ mobility and the sustainability goals of reducing energy usage and improving air quality.

Abstract: The American Society of Civil Engineers’ recent report on US infrastructure estimates that a $2.2 trillion investment would be needed to bring them up to par. An estimated 30% of the nation’s 10,000 steel railroad bridges and 600,000 highway bridges are either structurally deficient or functionally obsolete or both. Currently, most bridge inspections are visual only, which has been shown to be ineffective in identifying problems. Acoustic Emission (AE) testing is a comprehensive and effective way of detecting structural damage.

Abstract: 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.
