Visible to the public Quantitative Visual Sensing of Dynamic Behaviors for Home-based Progressive Rehabilitation

Submitted by yunfu on Mon, 11/10/2014 - 12:43pm. Contributor:

Abstract:

Human motion-capture and computational analysis tools have played a significant role in a variety of product-design and ergonomics settings for over a quarter-century. In moving beyond traditional kinematic (and its dual-static) settings, advances in biomechanics and multibody dynamics have led up to computational analysis tools that can provide significant insights into the functional performance.

Submitted by fborrelli on Mon, 11/10/2014 - 12:43pm. Contributors:

Abstract:

This project focuses on the formal design of semi-autonomous automotive Cyber Physical Systems (CPS). Rather than disconnecting the driver from the vehicle, the goal is to obtain a vehicle where the degree of autonomy is continuously changed in real-time as a function of certified uncertainty ranges in driver behavior and environment reconstruction.

Visible to the public Robust Algorithms for Mobile Robots to Learn Human Preferred Movement in a Hallway

Submitted by fuminz on Mon, 11/10/2014 - 12:43pm. Contributors:

Abstract:

We propose a dual expert algorithm (DEA) to assist a mobile robot in learning a person's preference of moving direction when the human encounters the robot in a typical hallway. When in use in hospital and office environments, a mobile robot will routinely encounter people who are not its primary user. These people need to feel comfortable around the robot for its implementation to be a success.

Visible to the public Resilient Wireless Sensor-Actuator Networks

Submitted by Hai Lin on Mon, 11/10/2014 - 12:26pm. Contributors:

Abstract:

Wireless sensor-actuator networks (WSAN) are systems consisting of numerous sensing and actuation devices that interact with the environment and coordinate their activities over a wireless communication network. WSANs represent an important class of cyber-physical system (CPS) found in our national civil infrastructure. This project addresses the issue of resilience in WSANs.

Visible to the public Sensing as a Service - Architectures for Closed-loop Sensor Network Virtualization

Submitted by mzink on Mon, 11/10/2014 - 12:26pm. Contributors:

Abstract:

The goal of this project is to demonstrate that new cyber physical architectures will enable closed--loop sensor networks to be shared among multiple applications and to dynamically allocate sensing and computing resources necessary to analyze sensor data and perform sensor actuation.

Visible to the public Semantics of Optimization for Real Time Intelligent Embedded Systems (SORTIES)

Submitted by feron on Mon, 11/10/2014 - 12:26pm. Contributors:

Abstract:

Optimization algorithms used in a real-time and safety-critical context offer the potential for considerably advancing robotic and autonomous systems by improving their ability to execute complex missions. However, this promise cannot happen without proper attention to the considerably stronger operational constraints that real time, safety-critical applications must meet, unlike their non-real-time, desktop counterparts.

Submitted by Xenofon Koutsoukos on Mon, 11/10/2014 - 12:26pm. Contributors:

Abstract:

The objective of this project is to develop a science of integration for cyber physical systems (CPS). The proposed research program has three focus areas: (1) foundations, (2) tools and tool architectures, (3) systems/experimental research. The project has pushed along several frontiers towards these overall objectives. In the following, we describe selected accomplishments:

Visible to the public Scalable Component-based Model Revision of Cyber-Physical Systems with Separation of Concerns

Submitted by sandeepkulkarni on Mon, 11/10/2014 - 12:26pm. Contributor:

Abstract:

As part of our CPS project, we have focused on the problem of model repair for cyber-physical systems. This work involves identifying constraints caused due to physical components during revision. We consider four types of constraints cyber-cyber, cyber-physical, physical-cyber and physical-physical. Based on the complexity limitations caused by these constraints we are developing efficient heuristics to mitigate the cost of model repair. We have also focused on extending revision to code level.

Visible to the public Safe Collaborating Intelligent Vehicles: Synchronized Clocks

Submitted by yitiangu on Mon, 11/10/2014 - 12:26pm. Contributors:

Abstract:

Our objective is to engineer vehicles that can collaborate on the use of a roadway. The protocols that define the collaboration must be provably safe, and the implementations of the protocols by different manufacturers must be guaranteed to inter-operate. As an example we are using a collaborative merge protocol, that assists a driver merging between two vehicles in an adjacent lane.
