We investigate the ability of a collection of deferrable energy loads to behave as a battery; that is, to absorb and release energy in a controllable fashion up to fixed and predetermined  limits on volume, charge rate and discharge rate. We derive bounds on the battery capacity that can be realized and show  that there are fundamental trade-offs between battery parameters.

Additive layer manufacturing has been termed as one of the proponents of the fourth industrial revolution. However, due to the presence of cyber and physical domain components in additive manufacturing, they are prone to physical-to-cyber domain attacks. One of the example of such attacks is side-channel attacks, where an attacker can steal valuable intellectual property of the 3D objects being printed by the additive manufacturing system. To understand and defend these attacks, we have to analyze all the possible side-channels and minimize the amount of leakage in each of them.

The poster provides a general overview of the motivation for testbeds, and summarizes the high-level objectives of the project. Then, the poster outlines a conceptual architecture of how a layered testbed architecture could be extended to realize federated testbeds. Followed by this, the poster provides a high-level conceptual architecture of the remote access framework developed as part of the project. The poster also provides some details on the various tasks performed as part of the remote access framework.

Having a shared and accurate sense of time is critical to distributed Cyber-Physical Systems (CPS) and the Internet of Things (IoT). Thanks to decades of research in clock technologies and synchronization protocols, it is now possible to measure and synchronize time across distributed systems with unprecedented accuracy. However, applications have not benefited to the same extent due to limitations of the system services that help manage time, and hardware-OS and

This Cyber-Physical Systems (CPS) project supports research to enable the automated monitoring of building and infrastructure construction projects. The purpose of construction monitoring is to provide developers, contractors, subcontractors, and tradesmen with the information they need to easily and quickly make project control decisions. These decisions have a direct impact on the overall efficiency of a construction project. Given that construction is a $800 billion industry, gains in efficiency could lead to enormous cost savings, benefiting both the U.S. economy and society.

This project addresses the safety and security issues that arise when giving users remote-access to a multi-robot research test-bed, where mobile robots can coordinate their behaviors in a collaborative manner. Through a public interface, users are able to schedule, and subsequently upload, their own code and run their experiments, while being provided with the scientific data produced through the experiment.

The smart grid is a large-scale, societal-level hybrid cyber-physical system with tight coupling between cyber and physical components.  Ensuring availability and reliability of power requires maintaining stability of the power grid even as increasing demand and uncertain renewable power sources push the power system close to its operation limit.  In addition, the cyber-enabled grid has multiple entry points, leaving it highly susceptible to cyber attacks by malicious adversaries.
