The terms denote engineering domains that have high CPS content.

Our overall aim in this project is to synthesize desired behaviors in populations of bacterial and mammalian cells. To this goal, we define the basis of a next-generation cyber-physical system (CPS) called biological CPS (bioCPS). The enabling technologies are synthetic biology and micron-scale mobile robotics. Synthetic genetic circuits for decision making and local communication among the cells are automatically synthesized using a Bio-Design Automation (BDA) workflow.

Cyber-physical processors work in harsh environments and often suffer very high operating temperatures. High temperatures accelerate processor aging and increase failure rate. Effective thermal-aware management is required to meet the computational demands of the application while reducing processor thermal stress.

The objective of this project is to improve the performance of autonomous systems in dynamic environments by integrating perception, planning paradigms, learning, and databases. For the next generation of autonomous systems to be truly effective in terms of tangible performance improvements (e.g., long-term operations, complex and rapidly changing environments), a new level of intelligence must be attained.

Robotic devices are excellent candidates for delivering repetitive and intensive practice that can restore functional use of the upper limbs, even years after a stroke. Rehabilitation of the wrist and hand in particular are critical for recovery of function, since hands are the primary interface with the world. However, robotic devices that focus on hand rehabilitation are limited due to excessive cost, complexity, or limited functionality. A design and control strategy for such devices that bridges this gap is critical.

A general model is developed to study how network routing can be reconfigured quickly without incurring transient congestion. Assuming both initial and target configurations are congestion-free, it is known that transient congestion may still occur during the reconfiguration process if links contain a mix of traffic flows following old and new routing rules, resulting from variation of switch reaction time and propagation delay differences among paths. We consider these factors by explicitly incorporating timing uncertainty intervals into the model.

This poster presents the Pulsar platform, which can achieve better than 5 nanosecond clock synchronization in an indoor environment combining wireless ultra-wideband communication with a chip-scale atomic clock. We discuss the various challenges in synchronization at nanosecond scales then propose and evaluate a proof-of-concept protocol for the same.
