A new brain-inspired architecture could improve how computers handle data and advance AI

Posted by in categories: physics, robotics/AI

General interest.


IBM researchers are developing a new computer architecture, better equipped to handle increased data loads from artificial intelligence. Their designs draw on concepts from the human brain and significantly outperform conventional computers in comparative studies. They report on their recent findings in the Journal of Applied Physics.

Today’s computers are built on the von Neumann architecture, developed in the 1940s. Von Neumann computing systems feature a central processer that executes logic and arithmetic, a memory unit, storage, and input and output devices. Unlike the stovepipe components in conventional computers, the authors propose that brain-inspired computers could have coexisting processing and memory units.

Mechanical engineers develop ways to improve windfarm productivity

Posted by in categories: energy, sustainability

You’ve probably seen them, perhaps on long roadtrips: wind turbines with enormous, hypnotic rolling blades, harnessing the clean power of wind for conversion into electric energy. What you may not know is that for the explosion in the number of wind turbines in use as we embrace cleaner sources of energy, these wind farms are quite possibly not as productive as they could be.

“We’ve been designing turbines for use by themselves, but we almost never use them by themselves anymore,” said UC Santa Barbara mechanical engineering professor Paolo Luzzatto-Fegiz, whose specialty lies in fluid mechanics. Historically, he said, were used individually or in small groups, but as the world moves toward greener technologies, they are now found in groups of hundreds or thousands.

The problem with these large installations is that each machine, which has been designed to extract as much energy as possible from oncoming , may not “play well” with the others, Luzzatto-Fegiz explained. Depending on how the turbines are situated relative to each other and to the prevailing wind, those not directly in the path of the wind could be left to extract energy from significantly depleted airflow.

Physicist Who Coined the ‘God Particle’ and Sold His Nobel Prize to Pay Medical Bills Dies at 96

Posted by in category: biotech/medical

Leon Lederman, the former head of the Fermi National Accelerator Lab and winner of the Nobel Prize in physics in 1988, died at a nursing home in Idaho on October 3rd. He was 96.

Lederman will perhaps best be remembered for coining the phrase “the God particle,” referring to the Higgs boson, which was theorized for decades before it was finally observed in 2012.

Wi-Fi 6 Is Coming: Here’s Why You Should Care

Posted by in categories: computing, internet, mobile phones

Get ready for the next generation of wifi technology: Wi-fi 6 (for so it is named) is going to be appearing on devices from next year. But will you have to throw out your old router and get a new one? And is this going to make your Netflix run faster? Here’s everything you need to know about the new standard.

A brief history of wifi

Those of you of a certain age will remember when home internet access was very much wired—only one computer could get online, a single MP3 took half an hour to download, and you couldn’t use the landline phone at the same time.

The History of Computing

Posted by in category: computing

In this video, we’ll be discussing the evolution of computing – more specifically, the evolution of the technologies that have brought upon the modern computing era.

[0:30–5:33] — Starting off we’ll look at, the origins of computing from as far back as 3000 BC with the abacus and progressing to discuss some of the first mechanical computers. After this, we’ll get to see the first signs of modern computing emerge, through the use of electromechanical relays in computers along with punched cards for data I/O.

[5:33–8:36] — Following that we’ll discuss, the 1st generation of modern computing, the vacuum tube era. The first technology that was fully digital and resembled how modern computers operate.
