The Rice labs of lead investigator Jun Lou, Pulickel Ajayan and Boris Yakobson, all professors in the university’s Mechanical Engineering and Materials Science Department, collaborated with Wigner Fellow Wu Zhou and staff scientist Juan-Carlos Idrobo at ORNL in an unusual initiative that incorporated experimental and theoretical work.
Waze's popular smartphone application combines GPS navigation software with social networking features, allowing users to improve the service's directions and traffic reports with their own data. This crowd-sourcing aspect enables the service to adapt to changing road conditions, such as accidents and speed traps, in real time.
Automakers have been trying to excite new-car buyers, especially younger ones, with dashboard infotainment systems that let drivers use voice commands do things like turning on windshield wipers, posting Facebook messages or ordering pizza. The pitch has been that hands-free devices are safer because they enable drivers to keep their hands on the wheel and their eyes on the road.
When Snowden, an employee of one of those firms, Booz Allen Hamilton, revealed details of two National Security Agency surveillance programs, he spotlighted the risks of making so many employees of private contractors a key part of the U.S. intelligence apparatus.
The scientists at the European Organization for Nuclear Research, known by its French acronym CERN, are searching for the first Web page. It was at CERN that Tim Berners-Lee invented the Web in 1990 as an unsanctioned project, using a NeXT computer that Apple co-founder Steve Jobs designed in the late 80s during his 12-year exile from the company.
Greenwald told The Associated Press the decision was being made on when to release the next story based on the information provided by Edward Snowden, a 29-year-old employee of government contractor Booz Allen Hamilton who has been accused by U.S. Senate intelligence chairwoman Sen. Dianne Feinstein of California of committing an "act of treason" that should be prosecuted.
Could radio-frequency signals become the next major energy source for industrial, scientific and medical (ISM) applications? At the IEEE International Microwave Symposium this week, NXP Semiconductors N.V. [NASDAQ: NXPI] is introducing the industry’s first complete RF power transistor portfolio designed specifically for the 2.45-GHz ISM frequency band, enabling RF energy to be used as a clean, highly efficient and controllable heat source.
M/A-COM Technology Solutions Inc. (MACOM) has introduced RoadScape at the Telematics Detroit Show in Novi, Michigan. RoadScape, MACOM’s innovative technology, provides highly accurate position, direction, and time information, enabling a new era of location and situational awareness for the automotive and transportation industry – allowing industrial and commercial vehicles to “predict the future.”
The benefits of radio frequency identification (RFID), which include better inventory management, improved operational efficiency, reduced labour, enhanced supply chain visibility, information accuracy, higher sales and better customer service, have spurred the technology’s adoption in various applications across verticals. The implementation of item-level tagging will further boost sale volumes and lend momentum to the global passive RFID.
The demand for wireless technologies continues to increase at rapid speeds, making RF power amplifiers a crucial component in wireless infrastructure equipment. Feedback from Wireless Design and Development's (WDD) readers suggests how power consumption, energy efficiency, and sustainability are important drivers in base station design for RF amplifiers.
Laws were passed to take up the fight against shadowy terrorists by giving authorities access to information that previously was off limits. At the same time, technologies intended to make Americans' everyday lives easier have also made it easier for corporations — and the government — to track their movements and habits.
A day after the presidents of China and the United States ended their first summit, pledges of cooperation by the two leaders faced an early test from an unexpected quarter -- an American intelligence contractor was leaking highly sensitive U.S. surveillance programs from his hiding place in the Chinese territory of Hong Kong.
Edward Snowden used the code name "Verax," truth-teller in Latin, as he made his cautious approach to Washington Post reporter Barton Gellman about disclosing some dramatic state secrets on intelligence gathering. The 29-year-old intelligence contractor said he knew the great risks he was taking in exposing a phone records monitoring program and an Internet scouring program designed by the U.S. government...
