The objective of this research is to investigate and implement a software architecture to improve productivity in the development of rapidly deployable, robust, real-time situational awareness and response (R3SAR) applications. The approach is based on a modular cross-layered architecture that combines a data-centric descriptive programming model with an overlay-based communication model.

This project aims to develop a new computing device where non-volatile elements based on flash (floating gate) transistors are pervasively used in all levels of the memory hierarchy to enable almost instantaneous check pointing and recovery of program state not subject to the data bus bandwidth limit. Effectively, this new system allows its power source to be cut off at any time, and yet resumes regular operation without loss of information when the power comes back.

This research aims to introduce methods to analyze the robustness of battery supported cyber physical systems under co-designed control, scheduling, and battery management algorithms. Robustness refers to the ability to maintain system performance under perturbations. Robustness in controller design has been well defined and understood for a large class of feedback control systems, yet robustness of scheduling and battery management algorithms is relatively less understood.

The objective of this research is to develop a trustworthy and high-performance neural-machine interface (NMI) that accurately interprets the user’s intended movements in real-time for neural control of artificial legs.

The objective of this research is to address challenges posed by the man-machine interface. Couched in the specifics of neuroprosthetic hands, this research seeks to develop transformative methods of human-machine communication and control to enhance the capabilities of currently-limited physical resources. In the grand vision of cyber-physical systems, these advancements translate into (i) communication of tactile sensation from a remote end-effector to a human user, (ii) division of control based on the spatial and temporal capabilities of the syst

Americans are living longer and more fulfilling lives. They desire to live as independently as possible, but independent lifestyles come with risks, such as debilitating falls that limit mobility. To address these issues, researchers are developing "smart home" technologies to enhance residents' safety and monitor health conditions using sensors and other devices. In particular, the continuous assessment of physical function is a key indicator of initial decline in health and functional ability.

The centerpiece of the activities to date on this project is the design, development, and implementation of the TimeTrial performance monitor. TimeTrial is a tool that enables observation of critical performance properties of streaming data applications without significantly perturbing the execution of the application under observation. It supports applications deployed on architecturally diverse computer systems, initially including the combination of multicore processors and/or field-programmable gate arrays (

This collaborative research project examines the role of software synthesis for monitoring and planning of autonomous sensors evolving on tidally forced rivers. The goal of the sensors is the coordinated sampling of currents and salinity to reconstruct the distributed state of the river. This project integrates the development of theory for the coordination of autonomous agents in motion-constrained environments, and of algorithms to perform motion planning tasks, with software tools for design, analysis, and code synthesis for implementation, as well as inverse modeling (i.e.

With the proliferation of personal mobile computing via mobile phones and the advent of cheap, small sensors, we propose that a new kind of “citizen infrastructure”, CitiSense, can be made pervasive at low cost and high value.
