SUMMARIES OF THE FY
2008 EFRI PROJECTSThe Emerging
Frontiers in Research and Innovation (EFRI) office awarded the following
12 grants in FY 2008.
LEARNING FROM THE BRAIN
Four awards fall under the topic Cognitive
Optimization and Prediction: From Neural Systems to Neurotechnology (COPN).
Creating a learning algorithm of the
brain
The project “Deep learning in the mammalian visual cortex” (grant
#0835878) will be led by Andrew Ng of Stanford, in collaboration with Ed
Boyden of Massachusetts Institute of Technology (MIT), Yann LeCun of New
York University, and Yang Dan of the University of California, Berkeley.
This project will employ high-performing
artificial neural network systems, new models of deep learning from
cognitive science, and new experiments on the visual cortex to begin
integrating what is known about the challenging task of recognizing
objects from visual inputs. The research will involve decisive
experiments to test assumptions about local feedback in the learning
system, the results of which may encourage new computational models of
the brain.
Studying
neural networks with an innovative patch-clamp array
The project “Dynamics of neural networks on a planar patch-clamp array:
training, identification, and control” (0835947) will be led by Russell
Tedrake of MIT, in collaboration with Alexandre Megretski and H.
Sebastian Seung of MIT and Hongkun Park of Harvard University.
This research has the potential to
revolutionize in vitro work on cells by solving technical problems with
planar patch-clamp arrays. (Patch-clamp arrays are tiny electrodes
placed within cells that can describe and control certain cell
activities.) If successful, the new patch-clamp arrays will be able to
monitor hundreds of cells effectively in parallel, a major step towards
interfacing with hundreds of neurons in the brain itself.
A second goal is to develop new, simplified
models of living neural circuits and to train these circuits to address
benchmark challenges that represent the cutting edge of robotics
research.
Determining how the brain controls the
hand
The project “Reverse-engineering the human brain’s ability to control
the hand” (grant #0836042) will be led by Francisco Valero-Cuevas of the
University of Southern California, in collaboration with Chang Liu of
Northwestern University, Yoky Matsuoka of the University of Washington,
and Emanuel Todorov of the University of California, San Diego.
The main goal of this project is to understand
how to achieve dexterous, approximately optimal control of a hand by
having humans and computers perform familiar but challenging tasks of
manipulating objects. Researchers will use the same algorithms both to
model human motor control and to go beyond the present state of the art
in robotic manipulation. Dexterous robotic hands have a wide variety of
possible applications in industry, space, and national security.
Improved understanding of how humans learn to optimize hand performance
will also have broader benefits, particularly for the disabled.
Modeling control of the electric power
grid on the brain
The project “Neuroscience and neural networks for engineering the future
intelligent electric power grid” (grant #0836017) will be led by Ganesh
Venayagamoorthy of the Missouri University of Science and Technology
(Missouri S&T, formerly University of Missouri-Rolla), in collaboration
with Donald Wunsch of Missouri S&T, and Ronald Harley and Steve Potter
of Georgia Institute of Technology.
While previous work on living neural networks
(LLNs) has focused on challenges like managing a single control
variable, electric power grids entail thousands of interconnected
variables that must be managed in real-time. The new work in vitro will
probe the ability of LNNs made up of thousands of cells to predict the
behavior of a complicated power grid simulator, and it will test the
ability of new biological learning models to explain their capabilities.
New mathematical concepts for how to cope with such complexity will also
be tested by addressing the same prediction challenge, and by attempting
to apply adaptive, anticipatory control for the first time to
large-scale power grid control in simulation.
BUILDING RESILIENT AND SUSTAINABLE
INTERDEPENDENT INFRASTRUCTURES
Eight awards fall under the topic of Resilient
and Sustainable Infrastructure (RESIN).
Considering air quality and water
availability in electricity production
The project “The interface of infrastructures, markets, and natural
cycles—Innovative modeling and control mechanisms for managing
electricity, water, and air quality in Texas” (grant #0835414) will be
led by David Allen of the University of Texas at Austin (UT), in
collaboration with Michael Webber and Roberton Williams of UT, and A.
Denny Ellerman and Ronald Prinn of MIT.
The project seeks to demonstrate that
integrating data on air quality and water availability into decisions
about electricity generation dispatch can make electricity generation
and water supply infrastructures more sustainable and resilient. Using
Texas as a test bed, the researchers will study, for example, how
changes to air quality regulations and electricity markets affect
resiliency and sustainability. This project’s use of such data provides
an opportunity for a paradigm-shift in the management of water supply
and electricity production.
Managing the risk of cascading failures
The project “Assessing and managing cascading failure vulnerabilities of
complex interdependent, interactive, adaptive human-based infrastructure
systems” (grant #0836047) will be led by Robert Bea of the University of
California, Berkeley, in collaboration with Berkeley colleagues John
Radke and Karlene Roberts.
The effects of Hurricane Katrina on the New
Orleans area have demonstrated the need to consider many factors besides
engineering in the reliability and performance of interdependent,
complex infrastructure systems. This project aims to develop new,
comprehensive risk assessment and management methods for such systems
that will take organizational and societal factors into account, in
addition to physical science and engineering.
The team will use the flood protection, water
distribution, and power supply systems of the Sacramento–San Joaquin
Delta area—aging systems that exist in a complex natural and human
environment—to address the probability and consequences of failure. The
ultimate goal is to improve their resiliency and sustainability while
preserving their performance.
Designing infrastructure for biofuels
The project “Interdependence, resilience and sustainability of
infrastructures for biofuel development” (grant #0835982) will be led by
Ximing Cai of the University of Illinois at Urbana-Champaign (UIUC) in
collaboration with four UIUC colleagues: Atul Jain, Madhu Khanna,
Gregory McIsaac, and Uyang Yanfeng.
The project seeks to develop strategies to
sustainably operate and expand the interdependent infrastructure systems
of the emerging bio-economy. In particular, it will examine the systems
used to develop biofuels from cellulosic feedstocks, including water
supply, energy supply, and transportation, and their vulnerability to
natural events and human factors. This research will answer timely and
important questions as the nation counts on biofuel providing a greater
share of its energy in the future.
Bringing energy and water to urban
areas
The project “Sustainable infrastructures for energy and water supply
(SINEWS)” (grant #0836046) will be led by John C. Crittenden of Arizona
State University (ASU), in collaboration with four ASU colleagues:
Samuel Ariaratnam, George Karady, Ke Li, and Charles Perrings.
How can growing cities ensure a reliable and
long-term supply of water and energy? This project aims to increase
understanding of how urban water and energy infrastructures depend on
one another and will examine the life-cycle implications of different
infrastructure options. Researchers will take into account risks
connected to the infrastructure’s physical and socio-economic
environments. Their overall goal is to maximize the resilience and
sustainability of energy and water infrastructure systems.
Supplying water where it is scarce
The project “Optimization of conjunctive water supply and reuse systems
with distributed treatment for high-growth, water-scarce regions” (grant
#0835930) will be led by Kevin Lansey of the University of Arizona (UA),
in collaboration with four UA colleagues: Robert Arnold, Guzin Bayraksan,
Christopher Choi, and Christopher Scott.
Planners in Southern Arizona and beyond must
make objective decisions about water systems, such as the use of dual
water distribution systems, the degree of decentralization, and the size
and timing of new facilities. This project will help planners make
decisions that meet growing demands for water while using less energy
and improving water quality. The researchers will develop a tool that
integrates water and wastewater infrastructures and can evaluate various
system configurations in the face of complex, competing objectives and
uncertainty. The tool will optimize for aspects of sustainability (for
example, maintenance costs, depletion of ecosystem water allocations,
and institutional limits on water reuse)—a critical consideration where
water is scarce.
Optimizing energy and transportation
infrastructures
The project “21st Century national energy and transportation
infrastructures: Balancing sustainability, costs, and resiliency
(NETSCORE-21)” (grant #0835989) will be led by James McCalley of Iowa
State University (ISU) in collaboration with four colleagues from ISU:
Dionysios Aliprantis, Konstantina Gkritza, Arun Somani, and Lizhi Wang.
The project aims to formulate optimal energy
and transportation infrastructure designs in terms of future power
generation technologies, energy transport and storage, and
hybrid-electric transportation systems, while balancing sustainability,
costs, and resiliency. The research will also identify and describe
interdependencies between the energy/vehicular transportation systems
and the energy resource portfolio. Outcomes of this research may
contribute to a national blueprint that will drive energy policy,
research, and investment for the next four decades.
Ensuring electricity and communications
in a catastrophe
The project “Resilient and sustainable interdependent electric power and
communications systems” (grant #0835879) will be led by Lamine Mili of
Virginia Polytechnic Institute & State University (VT). He will
collaborate with Sandeep Shukla and Michael von Spakovsky of VT,
Benjamin Hobbs of Johns Hopkins University, and Arnold Urken of Stevens
Institute of Technology.
When an electric power system fails, it can
affect the system’s own communications networks. This project will
develop complex systems theories to make these interdependent
infrastructures more robust, agile, and sustainable through the use of
sophisticated models and stabilization techniques and the involvement of
microgrids, which may generate power from renewable resources.
Integrating electric vehicles into the
grid
The project “A multi-scale design and control framework for dynamically
coupled sustainable and resilient infrastructures, with application to
vehicle-to-grid integration” (grant #0835995) will be led by Jeffrey
Stein of the University of Michigan-Ann Arbor (U-M). He will collaborate
with Zoran Filipi, Greg Keoleian, and Huei Peng at U-M and with Mariesa
Crow of Missouri University of Science and Technology.
Plug-in hybrid electric vehicles (PHEVs) link
transportation and electricity infrastructures by using grid electricity
to power the engine and, potentially, by sending stored electricity to
the grid (vehicle to grid, or V2G). How PHEVs are used may affect the
sustainability and resiliency of these infrastructures. The project will
quantify the infrastructure effects of PHEVs and design PHEV power
trains to balance the needs of both infrastructures. Researchers will
also develop power and energy management strategies that take into
account the various roles and interactions of PHEVs and electrical
grids. In particular, it will examine the distributed capacity provided
by V2G integration and the resulting abilities to accommodate renewable
resource intermittency and prevent and recover from catastrophic
failures.
