This talk addresses the challenge of integrating variable and uncertain renewable electricity sources into the grid, and focuses on what demand-side resources and energy storage can do to address these challenges.
UC Berkeley
The headquarters of CITRIS and the Banatao Institute are located in Sutardja Dai Hall (SDH) on the UC Berkeley campus. Specially designed to house this interdisciplinary research institute, the building contains 141,000 sq. feet of laboratory space for collaborative research, faculty offices, the 149-seat Banatao Auditorium, conference rooms on each floor, and modern classrooms. SDH also hosts the CITRIS Invention Lab, a rapid prototyping space used by UC entrepreneurs in our CITRIS Foundry startup accelerator program and the student maker community. The Marvell Nanofabrication Laboratory occupies a two-story, 15,000-square-foot wing of Sutardja Dai Hall where academic and industry researchers develop prototypes for new biosensors, photonics devices, and other MEMS/NEMS sensors. SDH is equipped with hundreds of sensors and sophisticated systems for building management that form a living laboratory on campus for energy research and proof-of-concept demonstrations.
EECS Colloquium: Feedback Motion Planning with Sum-of-Squares Verification
In this talk, I will present a nonlinear feedback control synthesis algorithm which combines randomized motion planning algorithms, popular in robotics, with sum of squares optimization. In order to drive the system to a goal state or limit cycle, the algorithm systematically populates the controllable subset of state space with a sparse set of trajectories which are locally stabilized with linear feedback and verified with sums of squares; we have now developed efficient methods for performing this verification along trajectories and around limit cycles, on systems with hybrid dynamics, and on systems with mixed polynomial/trigonometric nonlinearities.
Research Exchange: Ten Myths of ICT for International Development
The past decade has seen incredible interest in applying information and communication technologies for international development, an endeavor often abbreviated “ICT4D.”

As serious environmental issues become part of dinner conversation, utilities are faced with not only technology upgrades, but also dealing with new systemic impact that occur behind the meter.
Rebuilding Safe, Satisfactory, and Sustainable Houses After Earthquakes
Build Change is a non-profit social enterprise that designs earthquake-resistant houses in developing countries and trains builders, homeowners, engineers, and government officials to build them.
TRUST Security Seminar: Electronic Voting Security in India
India uses paperless electronic voting machines (EVMs) nationwide, and the Election Commission of India, the country’s highest election authority, has long maintained that the machines are “perfect,” “infallible,” and “fully tamper-proof.”
New Media RoundTable: Student Research Panel, Caitlin Marshall and William Brown III
Caitlin Marshall’s larger research focuses on voice prosthesis and synthesis, minority discourse, and the sound of civics. Each year in America ten to twelve thousand individuals undergo cancer treatment necessitating laryngectomy, the surgical removal of the larynx. With their sound sources removed, laryngectomees are rendered mute. To counter what many patients describe as the disability of silence, nearly all opt for prosthesis and speech therapy.
From Point to Pixel: Digitising Colour, Texture Shape and Size
The advent of image and laser based systems have increased the profile of photometric and geometric (colour, texture, shape and size) data capture, particularly in the 21st century.
Research Exchange: Formal Methods for Dependable Computing: From Models, through Software, to Circuits
Computing has become ubiquitous and indispensable: it is embedded all around us, in cell phones, automobiles, medical devices, and much more. This ubiquity brings with it a growing challenge to ensure that our computing infrastructure is also dependable and secure. We need to develop and maintain complex software systems on top of increasingly unreliable computing substrates under stringent resource constraints such as energy usage.

Semiconductor Nanowires for Solar Energy Conversion: Nano Seminar Series
Direct solar energy conversion to storable fuels offers a promising route toward less reliance on fossil fuels.
i4Energy Seminar: Energy Research and Commercialization at SRI
SRI International has been described as the birthplace of some of Silicon Valley’s most important innovations. With a corporate commitment to solving important problems, this talk will cover why SRI believes ensuring affordable, clean, and dependable energy supplies is one of the world’s important problems, highlight current energy projects, and describe SRI’s process for bringing its innovations to market.
BERC Fall Gala
The BERC Fall Gala is the signature fundraising event for Berkeley’s energy and resources community, bringing together industry and alumni with students and faculty to celebrate BERC’s fifth anniversary and to kick off the 2010-11 academic year.
TRUST Security Seminar: Secure Information Flow in Trust Networks
Who is responsible for the harm and risk of security flaws? The advent of worldwide networks such as the internet made software security (or the lack of software security) became a problem of international proportions. There are no mathematical/statistical risk models available today to assess networked systems with interdependent failures. Without this tool, decision-makers are bound to overinvest in activities that don’t generate the desired return on investment or under invest on mitigations, risking dreadful consequences. Experience suggests that no party is solely responsible for the harm and risk of software security flaws but a model of partial responsibility can only emerge once the duties and motivations of all parties are examine and understood. State of the art practices in software development won’t guarantee products free of flaws.
Research Exchange: Automatic Speech Recognition at 60: Old and Immature
Automatic Speech Recognition (ASR) is a venerable discipline, with significant research papers going back to the early 1950’s. Given this long history, ASR is often viewed as a mature field. However, like human beings, a research topic can be old without being mature.
The Evolving Internet: Driving Forces, Uncertainties, and Four Scenarios to 2025
What will the Internet be like in 2025? How much bigger will it have grown from today’s 2 billion users and $3 trillion market? Will it have achieved its full potential to connect the world’s entire population in ways that advance global prosperity, business productivity, education and social interaction?

TRUST Security Seminar: Return-Oriented Programming: The Impact of the Gadget on Civilization
Return-oriented programming is an attack technique that induces arbitrary behavior in the compromised program without injecting new code into its address space. A return-oriented attack combines short sequences of instructions from a target program’s executable image into a Turing-complete set of combinators, called “gadgets,” from which any desired functionality can be synthesized.
