Visible to the public CPS-VO: Active Resources

Abstract:

The Cyber-Physical Systems Virtual Organization (CPS-VO) was founded by NSF in 2010 to: (i) facilitate and foster interaction and exchanges among CPS PIs and their teams; (ii) enable sharing of artifacts and knowledge generated by the projects with the broader engineering and scientific communities; and (iii) facilitate and foster collaboration and information exchange between CPS researchers and industry.

Electricity usage of buildings (including offices, malls and residential apartments) represents a significant portion of a nation's energy expenditure and carbon footprint. Buildings are estimated to consume 72% of the total electricity production in the US. Unfortunately, however, 30% of this energy consumption is wasted. Virtual energy assessment is an approach that can optimize building energy efficiency and minimize waste at a low cost with minimal expert intervention.

Abstract:

Episodic brain disorders such as epilepsy have a considerable impact on a patient's productivity and quality of life and may be life-threatening when seizures cannot be controlled with medications. We will create a second generation brain-implantable sensing and stimulating device (BISSD) based on CPS principles and practice.

Visible to the public Research Platform for Quality of Time (QoT) Stack

Abstract:

Existing platforms are built with a static network connecting microprocessor, radio, clock system, and other components. This static configuration prevents researchers from experimentally validating the trade-offs between the way that clocks are conditioned and distributed, and the performance of the embedded system. In particular, such design decisions have major impact on time synchronization.

Visible to the public CRII: CPS: Architecture and Distributed Computation in the Networked Control Paradigm: An Autonomous Grid Example

Abstract:

This project is focused on developing a fundamental understanding of the impact of network delays and data drops using an approach that is applicable to a variety of Cyber-Physical Systems (CPS). An example of such a CPS is the power grid which includes large-scale deployment of distributed and networked Phasor Measurement Units (PMUs) and wind energy resources.

Visible to the public Multistep Electricity Price in Electricity Market in Smart Grid

The multistep electricity price (MEP) policy has been introduced to promote energy saving, load balancing, and fairness in electricity consumption. Nonetheless, with the development of the smart grid, how to determine the quantity of electricity and at what price in a step-like fashion has not been fully investigated in the past.

Visible to the public Synergy: Collaborative Research: Security and Privacy-Aware Cyber-Physical Systems

Abstract:

Security and privacy concerns in the increasingly interconnected world are receiving much attention from the research community, policymakers, and general public. However, much of the recent and on-going efforts concentrate on privacy in communication and social interactions. The advent of cyber-physical systems, which aim at tight integration between distributed computational intelligence, communication networks, physical world, and human actors, opens new possibilities for developing intelligent systems with new capabilities.

Visible to the public Quality of Time Architecture & APIs

Abstract:

Time is not necessarily what a clock reports. There is an uncertainty in time which is often not reported. Quantifying this timing uncertainty with clock parameters such as accuracy, precision, jitter or wander, is what introduces quality in time. Modern operating systems such as Linux lacks this perception of Quality of Time (QoT). It exposes some default clocks which are time synchronized / syntonized on best-effort basis through NTP or PTP, irrespective of the applications demand and the resources at hand.

Visible to the public Exploration of the Cyber-Physical Design Space

Abstract:

Generally, a cyber-physical-system (CPS) is one that combines computational and physical entities in a unified design effort. The design of CPSs needs good understanding of both subsystems, as small changes in the physical subsystem (PS) or the cyber subsystem (CS) may have significant consequences with respect to the overall system performance.

Visible to the public Defending Side Channel Attacks in Cyber-Physical Additive Layer Manufacturing Systems

Abstract:

Cyber-physical additive layer manufacturing, e.g. 3D printing has become a promising technology for providing cost, time, and space effective solution by reducing the gap between the designers and the manufacturers. However, the concern for the protection of intellectual property is arising in conjunction with the capabilities of supporting massive innovative designs and rapid prototyping.
