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:
One grand challenge facing the nascent field of cyber-physical systems is the human-machine interface. Complex systems such as teleoperated space robots, telesurgery robots, and wheel-chair mounted assistive robots involve various levels of human intervention and proximity of the human operator to the artificial system.

Abstract:
We propose concepts for intelligent, adaptive cyber-physical systems that adaptively control information acquisition through the choice of sensor configurations to interact with the physical environment. Our focus is on a novel aspect of cyber-physical systems, intelligent sensing, to control information acquisition under sensing budget constraints in support of critical decision tasks.

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:
This project focuses on modern buildings as a natural expression of a cyber--physical system, with many features that are typical to such systems. Modern buildings exhibit a tight integration of sensing, computation, and actuation within multiple physical domains. For example, larger buildings usually contain a sensor network, with a variety of sensors that measure power flow, temperature, relative humidity, carbon monoxide and carbon dioxide.

Abstract:
Teaching the methodologies of Cyber Physical System (CPS) design requires good examples that are easy to understand and tools that are commonly used in practice. This paper presents our experiences during the practical execution of model-driven design processes applying a range of state-of-the-art design tools for a novel and simple example from the CPS domain. The Falling Ball example has several properties that support teaching basic design principles of CPSs.

Abstract:
Cyber Physical Systems have revolutionized manufacturing to the point that next generation component manufacturing is now referred to as "digital manufacturing." Parts are made based on digital models that are represented by discrete points or meshes in standard file formats such as STL. The difficulty with these representations is that they can become extremely large when high resolution is desired.

Abstract:
Traditionally, buildings have been viewed as mere energy consumers; however, with the new power grid infrastructure and distributed energy resources, buildings can not only consume energy, but they can also output energy. As a result, this project removes traditional boundaries between buildings in the same cluster or between the cluster and power grids, transforming individual smart buildings into NetZero building clusters enabled by cyber-support tools.

Abstract:
Critical physical infrastructures, such as electrical grids and water networks etc., are increasingly controlled through a distributed cyber-systems which make it vulnerable to attacks. This project is devoted to developing the foundations of security of such cyber-physical systems.
