Road Revolution by Connecting Vehicles: Computational Framework for Optimizing Traffic Flow

Road Revolution by Connecting Vehicles: Computational Framework for Optimizing Traffic Flow

Drivers trying to get to work or home in a hurry know traffic congestion wastes a lot of time, but it also wastes a lot of fuel. In 2011, congestion caused people in US urban areas to travel an extra 5.5 billion hours and purchase an extra 2.9 billion gallons of fuel costing $121 billion. [...]

Ads in Free Mobile Apps have Hidden Costs for Both Users and Developers

Ads in Free Mobile Apps have Hidden Costs for Both Users and Developers

There’s no such thing as free — especially with smartphone apps, according to a new study. “Ads in ‘free’ apps drain your phone’s battery faster, cause it to run slower, and use more data,” said William Halfond, co-corresponding author of the study, which will be presented at the International Conference on Software Engineering (ICSE) in [...]

Where No Smartphone Has Gone Before

For the crew of the Starship Enterprise, Star Trek’s “Tricorder” was an essential tool, a multifunctional hand-held device used to sense, compute, and record data in a threatening and unpredictable universe. It simplified a number of Starfleet tasks, scientific or combat-related, by beaming sensors at objects to obtain instant results. The Tricorder is no longer [...]

Wearable Technology Can Help with Public Speaking

Wearable Technology Can Help with Public Speaking

Speaking in public is the top fear for many people. Now, researchers from the Human-Computer Interaction Group at the University of Rochester have developed an intelligent user interface for “smart glasses” that gives real-time feedback to the speaker on volume modulation and speaking rate, while being minimally distracting. The Rochester team describes the system, which [...]

Multiplying Mobile Devices’ Uploading Speed Tenfold

Multiplying Mobile Devices’ Uploading Speed Tenfold

A patent held by Universidad Carlos III de Madrid (UC3M) makes a jacket able to increase by tenfold the speed at which mobile devices can upload content. This is the MIMO HUB patent, which enables its jacket, in which numerous antennas are camouflaged, to connect to any mobile terminal in order to increase its data [...]

Does Your Password Pass Muster? Password Strength Meters Not All Created Equal

Does Your Password Pass Muster? Password Strength Meters Not All Created Equal

“Create a password” is a prompt familiar to anyone who has tried to buy a book from Amazon or register for a Google account. Equally familiar is that red / yellow / green bar that rates the new password’s strength. But when those meters give the go-ahead to passwords like Password1+, their effectiveness is called [...]

Mobile Battery Life can be Prolonged with System Settings

Mobile Battery Life can be Prolonged with System Settings

By using crowdsourced measurements researchers explain the energy impact of smartphone system settings, and their results show how to improve a mobile device’s battery lifetime by adjusting the settings. The NODES research group from University of Helsinki, Finland, has studied how the impact of different settings on battery lifetime can be estimated using crowdsourced measurements [...]

Computer Programming: System Automatically Finds Common Type of Programming Bug

Computer Programming: System Automatically Finds Common Type of Programming Bug

Integer overflows are one of the most common bugs in computer programs — not only causing programs to crash but, even worse, potentially offering points of attack for malicious hackers. Computer scientists have devised a battery of techniques to identify them, but all have drawbacks. This month, at the Association for Computing Machinery’s International Conference [...]

New Approach Uses ‘Twisted Light’ to Increase Efficiency of Quantum Cryptography Systems

New Approach Uses ‘Twisted Light’ to Increase Efficiency of Quantum Cryptography Systems

Researchers at the University of Rochester and their collaborators have developed a way to transfer 2.05 bits per photon by using “twisted light.” This remarkable achievement is possible because the researchers used the orbital angular momentum of the photons to encode information, rather than the more commonly used polarization of light. The new approach doubles [...]
