Vision-Correcting Displays: No Glasses Needed

Vision-Correcting Displays: No Glasses Needed

What if computer screens had glasses instead of the people staring at the monitors? That concept is not too far afield from technology being developed by UC Berkeley computer and vision scientists.   The researchers are developing computer algorithms to compensate for an individual’s visual impairment, and creating vision-correcting displays that enable users to see [...]

No-Wait Data Centers: Data-Transmission Delays Across Server Farms can be Reduced by 99.6 percent

No-Wait Data Centers: Data-Transmission Delays Across Server Farms can be Reduced by 99.6 percent

Big websites usually maintain their own “data centers,” banks of tens or even hundreds of thousands of servers, all passing data back and forth to field users’ requests. Like any big, decentralized network, data centers are prone to congestion: Packets of data arriving at the same router at the same time are put in a [...]

Protecting Privacy Online: New System Would Give Individuals More Control over Shared Digital Data

Protecting Privacy Online: New System Would Give Individuals More Control over Shared Digital Data

Cellphone metadata has been in the news quite a bit lately, but the National Security Agency isn’t the only organization that collects information about people’s online behavior. Newly downloaded cellphone apps routinely ask to access your location information, your address book, or other apps, and of course, websites like Amazon or Netflix track your browsing [...]

Computer Security: ‘Melbourne Shuffle’ Secures Data in the Cloud

Computer Security: ‘Melbourne Shuffle’ Secures Data in the Cloud

  To keep data safe in the cloud, a group of computer scientists suggests doing the Melbourne Shuffle. That may sound like a dance move (and it is), but it’s also a computer algorithm developed by researchers at Brown University. The computing version of the Melbourne Shuffle aims to hide patterns that may emerge as [...]

Censorship? Researchers develop ‘Encore’ to monitor Web access

Censorship? Researchers develop ‘Encore’ to monitor Web access

Georgia Tech researchers have created a tool to monitor the accessibility of Web pages around the world that can be installed by adding a single line of code to a web page. The tool, Encore, runs when a user visits a website where the code is installed and then discreetly collects data from potentially censored sites. [...]

Another Clue in Hunt for Dark Matter

Another Clue in Hunt for Dark Matter

The hunt for dark matter has taken another step forward thanks to new supercomputer simulations showing the evolution of our “local Universe” from the Big Bang to the present day.   Physicists at Durham University, who are leading the research, say their simulations could improve understanding of dark matter, a mysterious substance believed to make [...]

Demonstrating a Driverless Future

Demonstrating a Driverless Future

In the coming decades, we will likely commute to work and explore the countryside in autonomous, or driverless, cars capable of communicating with the roads they are traveling on. A convergence of technological innovations in embedded sensors, computer vision, artificial intelligence, control and automation, and computer processing power is making this feat a reality.   [...]

Move Over, Silicon: A New Circuit in Town

Move Over, Silicon: A New Circuit in Town

When it comes to electronics, silicon will now have to share the spotlight. In a paper recently published in Nature Communications, researchers from the USC Viterbi School of Engineering describe how they have overcome a major issue in carbon nanotube technology by developing a flexible, energy-efficient hybrid circuit combining carbon nanotube thin film transistors with [...]

Turing Test Success Marks Milestone in Computing History

Turing Test Success Marks Milestone in Computing History

An historic milestone in artificial intelligence set by Alan Turing — the father of modern computer science — has been achieved at an event organised by the University of Reading.   The 65 year-old iconic Turing Test was passed for the very first time by supercomputer Eugene Goostman during Turing Test 2014 held at the [...]

New Laser Sensing Technology for Self-Driving Cars, Smartphones and 3-D Video Games

New Laser Sensing Technology for Self-Driving Cars, Smartphones and 3-D Video Games

A new twist on 3-D imaging technology could one day enable your self-driving car to spot a child in the street half a block away, let you answer your Smartphone from across the room with a wave of your hand, or play “virtual tennis” on your driveway.   The new system, developed by researchers at [...]
