Visible to the public Context-dependent control of smart artificial hands through enhanced touch perception and mechatronic reflexes

Submitted by vjsantos on Mon, 10/28/2013 - 5:22pm. Contributors:

Abstract:

One grand challenge facing the nascent field of cyber-physical systems is the human-machine interface. Complex systems such as teleoperated space robots, telesurgery robots, and wheel-chair mounted assistive robots involve various levels of human intervention and proximity of the human operator to the artificial system.

Visible to the public Sequential Supervised Learning

Submitted by Venkatesh Saligrama on Mon, 10/28/2013 - 5:14pm. Contributor:

Abstract:

We propose concepts for intelligent, adaptive cyber-physical systems that adaptively control information acquisition through the choice of sensor configurations to interact with the physical environment. Our focus is on a novel aspect of cyber-physical systems, intelligent sensing, to control information acquisition under sensing budget constraints in support of critical decision tasks.

Submitted by Umit Ozguner on Mon, 10/28/2013 - 5:06pm. Contributors:

Abstract:

This study attempts to address a range of problems associated with autonomous navigation in real-life urban traffic, most recently including controller design and safety, secure communication, mapping, pedestrian behavior, testing and intersection access.

Visible to the public CEEMS – Cyber Enabled Energy Management of Structures

Submitted by Tyrone Vincent on Mon, 10/28/2013 - 4:52pm. Contributors:

Abstract:

This project focuses on modern buildings as a natural expression of a cyber--physical system, with many features that are typical to such systems. Modern buildings exhibit a tight integration of sensing, computation, and actuation within multiple physical domains. For example, larger buildings usually contain a sensor network, with a variety of sensors that measure power flow, temperature, relative humidity, carbon monoxide and carbon dioxide.

Visible to the public A Ball Goes to School - Our Experiences from a Cyber Physical Systems Design Experiment

Submitted by givargis on Mon, 10/28/2013 - 4:49pm. Contributors:

Abstract:

Teaching the methodologies of Cyber Physical System (CPS) design requires good examples that are easy to understand and tools that are commonly used in practice. This paper presents our experiences during the practical execution of model-driven design processes applying a range of state-of-the-art design tools for a novel and simple example from the CPS domain. The Falling Ball example has several properties that support teaching basic design principles of CPSs.

Visible to the public Converting Multi-Axis Machine Tools into Subtractive3D Printers by using Intelligent Discrete Geometry Data Structures

Submitted by Thomas Kurfess on Mon, 10/28/2013 - 4:40pm. Contributor:

Abstract:

Cyber Physical Systems have revolutionized manufacturing to the point that next generation component manufacturing is now referred to as "digital manufacturing." Parts are made based on digital models that are represented by discrete points or meshes in standard file formats such as STL. The difficulty with these representations is that they can become extremely large when high resolution is desired.

Submitted by suhas on Mon, 10/28/2013 - 3:40pm. Contributors:

Abstract:

Critical physical infrastructures, such as electrical grids and water networks etc., are increasingly controlled through a distributed cyber-systems which make it vulnerable to attacks. This project is devoted to developing the foundations of security of such cyber-physical systems.

Visible to the public Boolean Microgrid

Submitted by mazumder on Mon, 10/28/2013 - 3:37pm. Contributors:

Abstract:

The Boolean Microgrid (BM) emulates the Internet by supplying discrete power and discrete data over a network link that follows Boolean logic and is not continuous as in a conventional 60-Hz-ac or dc microgrid. BM is thus a highly integrated cyber-physical system (CPS) that features the convergence of control, communication and the physical plant.

Visible to the public Sensor Lattices

Submitted by mkatsev on Mon, 10/28/2013 - 3:23pm. Contributors:

Abstract:

Using the newly introduced idea of a sensor lattice, this project conducts a systematic study of the "granularity" at which the world can be sensed and how that affects the ability to accomplish common tasks with cyberphysical systems (CPSs). A sensor is viewed as a device that partitions the physical world states into measurement-invariant equivalence classes, and the sensor lattice indicates how all sensors are related.

Visible to the public Control Subject to Human Behavioral Disturbances: Anticipating Behavioral Influences in the Control of Diabetes

Submitted by patek on Mon, 10/28/2013 - 11:45am. Contributor:

Abstract:

This project addresses the design of cyber-physical systems that respond to behavioral disturbances introduced by human users. The primary motivating example of this research is the design of "artificial pancreas" algorithms for the control of blood glucose in patients with Type 1 diabetes who require external insulin throughout the day to maintain glucose homeostasis.
