Visible to the public Event-Based Information Acquisition, Learning, and Control in High-Dimensional Cyber-Physical Systems

Submitted by Andrea Goldsmith on Mon, 11/10/2014 - 12:44pm. Contributors:

Abstract:

The objective of this project is to develop a theoretical framework for stochastic learning, decision-making, and control in high-dimensional cyber-physical systems. In our general framework, decision makers dynamically refine their estimates of the time-varying physical system based on acquired information, which may be obtained by distributed sensors.

Submitted by givargis on Mon, 11/10/2014 - 12:44pm. Contributor:

Abstract:

The overall objective of this project is to create a general CPS design-science that makes design of every CPS simpler, faster and more dependable, while at the same time reducing the cost and the required expertise level. In order to master this challenge, we address four fundamental and closely related issues:

Submitted by asanchez on Mon, 11/10/2014 - 12:44pm. Contributors:

Abstract:

Managing and processing big amounts of data typically consumes large amounts of energy and computing time. These type of problems frequently occur in modern data centers. To solve this problem we can utilize parallel computing which is the most used way to carry out, manage and proces data faster. It is necessary to locate techiniques for energy efficient computation.

Submitted by ashutosh on Mon, 11/10/2014 - 12:44pm. Contributors:

Abstract:

Wireless body area sensing networks (WBANs) have the potential to revolutionize health care in the near term and enhance other application domains including sports, entertainment, military and emergency situations. These WBANs represent a novel cyber-physical system that unites engineering systems, the natural world and human individuals.

Visible to the public Harnessing the Automotive Infoverse

Submitted by Ramesh Govindan on Mon, 11/10/2014 - 12:44pm. Contributors:

Abstract:

Until now, the "cyber" component of automobiles has consisted of control algorithms and associated software for vehicular subsystems designed to achieve one or more performance, efficiency, reliability, comfort, or safety (PERCS) goals, primarily based on short-term intrinsic vehicle sensor data. However, there exist many extrinsic factors that can affect the degree to which these goals can be achieved.

Visible to the public GoingEasy with Crowdsourcing - Building Cyber-Physical Systems for People with Visual Impairment

Submitted by Baoxin Li on Mon, 11/10/2014 - 12:44pm

Abstract:

Many practical barriers continue to exist for a blind individual who strives to live an independent and active life, despite decades of development of assistive technologies. This project addresses the following two most prominent challenges: (1) disparity in information-sharing among people with visual impairment and its limited understanding by the research community; and (2) lack of methods and tools for effectively addressing the disparity.

Visible to the public Generalized Synchronization Trees

Submitted by Rance Cleaveland on Mon, 11/10/2014 - 12:44pm. Contributors:

Abstract:

The PIs are developing their novel modeling paradigm, Generalized Synchronization Trees (GSTs), into a rich framework for both describing cyber-physical systems (CPSs) and studying their behavior under interconnection. GSTs were inspired by Milner's use of Synchronization Trees (STs) to model interconnected computing processes, but GSTs generalize the mathematical structure of their forebears in such a way as to encompass many classes of CPSs.

Visible to the public Foundations of Secure Cyber Physical Systems

Submitted by suhas on Mon, 11/10/2014 - 12:44pm. Contributors:

Abstract:

Cyber-physical systems regulating critical infrastructures, such as electrical grids and water networks, are increasingly geographically distributed, necessitating communication between remote sensors, actuators and controllers. The combination of networked computational and physical sub- systems leads to new security vulnerabilities that adversaries can exploit with devastating consequences.

Submitted by lrohrbough on Mon, 11/10/2014 - 12:44pm. Contributors:

Abstract:

Cyber-Physical Systems (CPS) are being increasingly deployed in critical infrastructures such as electric-power, water, transportation, and other networks. These deployments are facilitating real-time monitoring and closed-loop control by exploiting the advances in wireless sensor-actuator networks, the internet of "everything," data-driven analytics, and machine-to-machine interfaces. CPS operations depend on the synergy of computational and physical components.
