Machining is a fundamental processing capability critical to production of end-user goods and systems, as well as components used in virtually every industrial process. Machine tool programming to support these processes is critical for production and cost estimation. Unfortunately, currently available automated process planning methods constrain the process along geometrically simple trajectories due to computational constraints, this at the sacrifice of final processing efficiency.

Ocean Big Data (OBD) is an emerging area of research that benefits ocean environmental monitoring, offshore exploration, disaster prevention, and military surveillance. It is now affordable for oil and gas companies, fishing industry, militaries, and marine researchers to deploy physical undersea sensor systems to obtain strategic advantages. However, these sensing activities are scattered, isolated, and often follow the traditional "deploy, wait, retrieve, and post-process" routine.

Explanation of Demonstration: Traffic waves will arise in the absence of bottlenecks as a result of human driving behavior alone. We conduct an experiment on a ring-road track to demonstrate the ability of a single autonomous vehicle in a flow of human-piloted vehicles to dampen these waves. In this demonstration, we presented a virtual reality video of the experiment.

Stroke is a leading cause of long-term disability, with 80% of survivors having locomotor impairments. Individuals after stroke typically present with hemiparetic gait, characterized as slow, asymmetric, and inefficient. Our lab has been developing soft wearable cyber-physical sytems, called soft exosuits, that interface with paretic limb after stroke through soft and conformal textile-based structures to assist hemiparetic walking. Soft exosuits transmit mechanical power to human body joints via interaction between functional textiles worn on the body and Bowden cable retraction.

The exponential growth of information and communication technologies have caused a profound shift in the way humans engineer systems leading to the emergence of closed-loop systems involving strong integration and coordination of physical and cyber components, often referred to as cyber-physical systems (CPSs). Because of these disruptive changes, physical systems can now be attacked through cyberspace and cyberspace can be attacked through physical means.
