UFL Thermal Plume Simulation
Simulations of thermal plumes addressed.
HiPerGator Simulations 'Solve Mother Nature' to Address Real-World Problems
University of Florida News, Eric Hamilton
September 20, 2022
University of Florida (UF) researchers reproduced the turbulence and complexity of thermal wall plumes using the university's HiPerGator supercomputer. The complexity of air movements long made it impossible to perform detailed simulations of hot air rising along a vertical surface, but the supercomputer enabled researchers to track air movements on the sub-millimeter level. The simulation utilized 125 of the HiPerGator AI cluster's 140 nodes, each of which hosts eight graphics processing units and 128 central processing units. Said UF's Sivaramakrishnan Balachandar, "Using computers, we solve Mother Nature, and what the computer simulation gives us is unprecedented access into all the details of what happens inside. With our simulation, we can go into the wall plume and see every nook and cranny."

Hacking Smartphones
Note this requires device proximity
Hacking Device Can Secretly Swipe, Tap Smartphone Screen
New Scientist
Jeremy Hsu, August 31, 2022
Separate teams of researchers have developed devices for remotely hacking smartphone touchscreens. Both methods involve placing devices featuring an antenna for transmitting signals and a phone locator under a table. The locator deduces the position and orientation of a touchscreen device placed on the table, then the antenna sends electromagnetic signals imitating electric field disturbances caused by physical touch. The Invisible Finger method created by University of Florida researchers caused both iOS and Android devices to recognize the electromagnetic touches; the GhostTouch technique from scientists at China's Zhejiang University worked with multiple Android devices, but could not crack the iPhone 7 Plus or certain OPPO phone models. The hacks only work with the target device lying face down and positioned close to the antenna.

Voice-assisted AI is Becoming smarter, but Consumers have Higher expectations
I see here is a post by a former school of mine ... Some reasonable thoughts.
Voice-assisted AI is becoming smarter, but consumers have higher expectations by University of Florida
When Huan Chen started researching how consumers think about and perceive artificial intelligence in marketing communications, she was surprised at a major finding: They understand marketing and think it's unavoidable today.
"Marketing companies and organizations will take advantage of new technology," said Chen, and consumers understand that, just like they now have no or low expectations of privacy. "They know these kinds of devices can cache data all the time, (and) if you buy this device, you know you sacrifice your privacy."
Chen, an associate professor in the Department of Advertising, with Telecommunication Professor Sylvia Chan-Olmsted and graduate students Julia Kim and Irene Sanabria, recorded 20 consumers using AI devices and then conducted in-depth interviews to gauge their perspective. Her findings are presented in the paper "Consumers' Perception on Artificial Intelligence Applications in Marketing Communication."
Most people have a general understanding of artificial intelligence used in devices like Amazon's Alexa and Google Home, Chen said. In comparing AI to humans, "they think of AI as smart and intelligent but not as sophisticated or complicated enough. Even though they communicate and interact with AI, they still don't think AI can do complicated or sophisticated tasks. They think human beings still need to do that kind of task."
Some people wish AI devices could master more functions to help them with their daily lives, Chen said. For now, how they are using voice-assisted AI focuses on five aspects:
Function: Consumers understand and appreciate the various functions AI can offer, like "Alexa, play music" or "Find a recipe."
Communication: "Consumers have a love/hate relationship with AI," she said. "They are frustrated, especially if the device couldn't recognize what they are talking about."
Adaptation: How does AI adapt to users during communications and interactions, and vice versa? "The voice-assisted devices using AI have become smarter and smarter to know users better. At the same time, human beings also adjust and change. One man figured out a way to give an order, to talk to Alexa to make that communication more effective. That's a mutual adaptation."
People are cautious about their relationships with AI.
Privacy: Privacy is still an issue, Chen said, but not as much as it once was. Technology may be desensitizing some people, who now think their data is being collected everywhere, all the time. Others "do not think they are so important that people will do something with the data." ... '

UF Acquires NVidia DGX System
UF becomes first U.S. university to acquire cutting-edge NVIDIA DGX A100 system, advancing its artificial intelligence initiative - News - University of Florida
Moving forward on its sweeping vision to transform the future of education through artificial intelligence (AI), the University of Florida is collaborating with technology company NVIDIA to acquire the world’s most advanced AI system to boost the performance of UF’s powerful supercomputer.
UF today announced it will be the country’s first higher education institution to acquire the new NVIDIA DGX™ A100 — the world’s most advanced AI system.
The new systems are scheduled to arrive at UF at the end of May and mark a significant step in the university’s bold initiative to become a national leader in the application of AI, an expansive plan that will elevate UF in research, teaching, and economic development. The initiative includes a commitment from UF to hire 100 faculty members specifically focused on AI, in addition to the 500 new faculty hired across disciplines -- many of whom will integrate AI into their teaching and research. UF is also embarking on a unique plan to infuse AI across academic majors, creating a next generation AI-enabled workforce and democratizing a technology that has the potential to solve some of the globe's most formidable challenges. ...

Simulating Molecular Motion with Neural Networks
Researchers Cast Neural Nets to Simulate Molecular Motion
Los Alamos National Laboratory News
By Nancy Ambrosiano July 2, 2019
The U.S. Department of Energy's Los Alamos National Laboratory (LANL), the University of North Carolina at Chapel Hill, and the University of Florida demonstrated that artificial neural nets can be taught to encode quantum mechanical laws that define molecular motion, potentially advancing simulations across many disciplines. Said LANL's Justin Smith, "We can now model materials and molecular dynamics billions of times faster compared to conventional quantum methods, while retaining the same level of accuracy." The researchers developed a machine learning technique to build empirical potentials—atomic dynamics descriptions that follow classical physical and Newtonian laws—from data collected about millions of compounds. The transfer learning technique can be applied to new molecules in milliseconds .... "
