Simulation-based Disaster Damage Prediction and Damage Assessment

Manmade and natural disasters including blasts, fragment impacts, penetration, earthquakes and landslides pose severe threats to our living environment. Disaster prediction and mitigation are now a timely research topic for safeguarding our society. Computer simulations with robust numerical algorithms are one effective approach for disaster prediction and mitigation. I will introduce meshfree-based computation methods for multi-scale, multi-physics simulation of damage initiation, propagation, and total collapse in structures and systems subjected to extreme events. I will also discuss how verification and validation of numerical simulation play an important role in the reliability of disaster prediction.

In addition, I will introduce the recently formed Center for Extreme Events Research (CEER) at UC San Diego. The Center specializes in developing state-of-the-art computational and experimental technologies for protection of critical infrastructure and bio-systems from extreme hazardous events, and for mitigation of structures and systems after disasters. Our unique testing facilities, including the blast simulator and impact testing laboratory, will be highlighted along with our advanced computational techniques, such as the Reproducing Kernel Particle Method and Isogeometric Analysis.

Visual Computing: Grand Opportunities

Mobile phones with associated imaging devices are now ubiquitous. Most of human perception, however, is from visually rich content, and the mobile revolution should fundamentally be about visual computing. Indeed, we are seeing a revolution in mobile image sensors from Kinect-style hand-held RGBD cameras, to light field cameras used for 3D and range imaging, to wearable see-through and head-mounted augmented reality displays. In short, visual computing at the interface of computer vision and computer graphics is undergoing a major transformation that impacts our daily lives.

Visual content can increasingly be created in more realistic ways, rivaling real photographs and fulfilling the long-term goal of photorealism in computer graphics. Numerous blockbuster movies featuring computer-generated visual effects that are indistinguishable from reality have had tremendous success. But a key challenge remains: creating these effects in real-time and integrating them with mobile augmented reality systems to extend human perception and enable entirely new tasks.

Another major trend is the coming of age for computer vision, where tasks like scene comprehension and gesture recognition are now becoming commonplace on mobile devices. The confluence of these trends opens up great challenges and opportunities.

The UC San Diego Center for Visual Computing seeks to develop the fundamental technologies needed to take full advantage of these opportunities, transforming the way we experience and display visual content and indeed the way we live.

The Future of Sustainable Power and Energy

Energy storage in the electrochemical form is attractive because of high efficiency and fast response time. New and improved materials for electrochemical energy storage are urgently needed to make more efficient use of our finite supply of fossil fuels and to enable the effective use of renewable energy sources. In this talk, I will discuss new perspectives for energy storage materials being pursued at our new Sustainable Power and Energy Center. The work includes new-generation lithium-ion batteries, new sodium-ion batteries and other battery chemistries with lower costs and longer cycle lives. I hope to demonstrate how to combine knowledge guided synthesis-and-characterization with computational modeling to develop and optimize new higher energy/power density electrode materials for energy storage. With recent advances in characterization tools and computational methods, we are able to map out the structure-properties relations in functional materials for energy storage and conversion, and design and optimize the next generation energy storage technologies.

Seamless Integration of Wearable Medical Devices

Wearable devices have the potential to revolutionize how we practice health care, train athletes and support the health and performance of our troops. Unfortunately current-generation wearables can be large and bulky with limited battery life and only measure a small handful of parameters that have limited clinical utility. The Center for Wearable Sensors endeavors to build new sensing devices that measure useful parameters that can help directly affect patient healthcare and behavior, while doing so with ultra-miniaturized sensing electronics that are either extremely energy-efficient or support energy harvesting for seamless integration into daily life. This talk outlines these challenges and proposes several promising solutions, with an emphasis on new bio-energy harvesting technologies.
