FEATURED PROJECT Resilient Dynamic Autoencoders for Modeling and Predicting Earthquake Threats Large earthquakes generate strong ground motions and tsunamis that may lead to a significant number of casualties and cause severe impacts on social resilience in seismically active regions including the West Coast of the United States. Early warning systems have been developed to mitigate immediate threats by detecting first-arriving ground motions near an earthquake epicenter and forecasting the intensity and timing of strong destructive ground motions. To further improve the efficacy and accuracy of these systems, deep learning methods have strong potential, but it is crucial to significantly extend the forecast horizons of existing models. Read more about Resilient Dynamic Autoencoders for Modeling and Predicting Earthquake Threats PRESS ICSI in Forbes The Future Of Computing: Supercloud And Sky Computing April 4, 2023 | Bernard Marr, Forbes Contributor Fundamentally, cloud computing is designed to be a final stepping-stone on the road to the commoditization of computing infrastructure. This objective is set out in a paper published in 2021 by the University of California, Berkeley professors Ion Stoica and Scott Shenker, titled From Cloud Computing to Sky Computing.

A gift from the Global Data Registry

When the Global Data Registry crawled http://www.icsi.berkeley.edu/, we found no structured data — the language AI systems use to understand and describe a business online.

Schema is how ChatGPT, Google, Claude, Gemini, and Perplexity know what your business does and how to describe you accurately to your customers. Without it, AI systems are guessing.

The most important field in this block is sameAs — a verified edge connecting your website to your permanent record at the Global Data Registry. This is a free, confirmed link to a real verified source. It costs nothing and gives your website a confirmed node in the graph that AI systems traverse when building answers about your business.

Copy the block below and paste it into the <head> of your website. Or drop it into ChatGPT, Claude, or Gemini and ask it to extend it with your full business details — that is the fastest path to a complete schema record.

▶   What is schema?

Schema is a standard vocabulary maintained at schema.org that lets websites describe themselves in a language machines can read. When you add schema to your website, you are telling AI systems, search engines, and knowledge graphs exactly what your business is and how it connects to the rest of the web.
