i4Energy Seminar: Legal implications of Climate Modeling
This presentation discusses the uses and limitations of these models for courts and agencies. Climate scientists have created a unique institutional system for assessing and improving models, going well beyond the usual system of peer review. Consequently, their conclusions should be entitled to considerable credence by courts and agencies.

Research Exchange: Advancing Health Through Technology: The Vision of the Betty Irene Moore School of Nursing at UC Davis
A nurse leader, educator and scientist and a nationally-recognized expert in gerontological nursing and rural health care, Heather M. Young was appointed Associate Vice Chancellor for Nursing at UC Davis Health System in 2008. She also serves as the founding Dean of the Betty Irene Moore School of Nursing at UC Davis.
i4Energy Seminar: The Challenges of Solar Forecasting: Reducing the Cost of Solar Power Through Research
The Solar Forecasting Laboratory at the University of California Merced has collected over 15 months of high quality horizontal and direct normal irradiance measurements at different wavelengths (UV, IR and visible) with the primary objective of developing, calibrating and benchmarking novel and more accurate forecasting models for solar irradiance at the ground level. Without effective forecasting methodologies, neither solar nor wind power plants cannot be effectively connected to the power grid, which presents a major obstacle for high-penetration utilization of intermittent sources.
Research Exchange: Secure, Insure, or Ignore? Economics of Information Security
Are we investing too little in information security? Are we investing too much? Since Anderson and Varian posed these questions in 2002, much progress has been made in understanding rational decision-making in information security.
i4Energy Seminar: Simulating California’s High Renewables Future
California ISO operates much of the California power grid. The ISO works with federal regulators, State agencies and market participants to conduct grid planning, improve system operations, and adapt wholesale markets for energy and ancillary services in anticipation of achieving a 20% renewable portfolio standard (by about 2013) and then a 33% renewable portfolio standard by 2020.
Research Exchange: Molecule Counting Technology for Personalized Healthcare
Knowledge is power. Knowing of the quantities of specific molecules present in a biological system is fundamental to understanding systems level operation. This understanding is critical for translating basic knowledge of specific molecules into applied medical, agriculture, forensic, and drug development assays, and has created a need for methods that more accurately quantify an ever-increasing number of newly identified analytes with greater precision.
CITRIS newsletter about Marvell Lab
The April newsletter is online and focuses on the happenings of the Marvell Nanolab.
i4Energy Seminar: Legal issues in Energy Policies and Climate Change
Although the Smart Grid promises to help meet goals of energy efficiency and renewability, incorporating IT into the electric grid poses new and substantial risks to individual privacy. At the same time, Smart Grid deployment is proceeding along a path that could make it difficult for individuals to control the flow of information about their energy use while also raising barriers in the market for in-home smart devices.
Research Exchange: Abstracting Traditional Roles in Scientific Discovery and Inference: Application to Real-Time Astronomy
The collection of new data in any discipline does not, in general, lead to the creation of new knowledge. As a stream of data transforms to a deluge, the human role in scientific discovery, traditionally so important, must be partially fulfilled by powerful algorithms.
Smaller Keeps Getting Bigger: Marvell Lab Kicks into Gear
If small was beautiful, nano is stunning.
i4Energy Seminar: Electrical Efficiency Trends of Computation over Time
This talk will describe long-term trends in the electrical efficiency of computation that enabled the development of laptops and other mobile computing devices. If these trends continue, they presage continued further improvements in battery powered computers, sensors, and controls.
Research Exchange: Security For and From GPS
These days, GPS is used by all of us, and our application space is partially spanned by the following far-flung examples. Several hundred million GPS chip sets were shipped as part of cell phones last year, where they added about $2 to the bill or materials. These will support consumer applications like location specific advertising.
i4Energy Seminar: Smart Grid – What is it and Why is it Necessary?
While there has been significant press attention towards the “smart grid”, there has been little public discussion of what a smart grid is, and the follow on question of why is it necessary. To many, smart grid means smart meters; however, meters are the tip of iceberg. Unravel the mystery as SDG&E, one of the leading utilities in the smart grid arena nationwide, provides a definition of the smart grid and, more importantly why it is imperative, particularly in California.
Research Exchange: Meta Mouse
Enabling computer-based education in the developing world requires addressing significant resource limitations. Students often sit with two or more peers at a computer, and learning in this environment can be a challenge. For this reason, the idea of multiple-mouse interfaces has gained traction, allowing each student to directly interact with educational applications. However, major roadblocks exist to adoption and use of these technologies.
CITRIS / BSAC Workshop Sensors: Power Distribution: Operation, Fault Detection, and Maintenance
This workshop aims at bringing together researcher and presentations related to diagnostic methods and sensors for enhancing the reliability and improving fault detection for the power distribution grid. Among other, our goal is to stimulate the discussion on how such sensors and diagnostics/fault information can be integrated into the upcoming “Smart Grid” infrastructure.
CITRIS/CSE talk on Science and the Elimination of Nuclear Weapons
How can science support efforts to reduce and eventually eliminate nuclear weapons and strengthen non-proliferation? Science and scientists have been engaged in support of many security building and arms control and disarmament efforts within different political and administrative frames.
