The Intelligent Intersection Could Banish Traffic Lights Forever

Slashdot - Wed, 10/05/2017 - 1:00pm
Jonathan M. Gitlin reports via Ars Technica: With a degree of coordination -- between vehicles, and with traffic infrastructure -- traffic chaos should theoretically be banished, and less congestion means fewer pollutants. Clemson researcher Ali Reza Fayazi has provided a tantalizing glimpse at that future, a proof-of-concept study showing that a fully autonomous four-way traffic intersection is a hundred times more efficient at letting traffic flow than the intersections you and I currently navigate. Because cars don't sit idling at the lights, Fayazi calculated it would also deliver a 19 percent fuel saving. Fayazi designed an intersection controller for a four-way junction that tracks vehicles and then uses an algorithm to control their speeds such that they can all pass safely through the junction with as few coming to a halt as possible. What makes the study particularly interesting is that Fayazi demonstrated it by interspersing his own physical car among the simulated traffic -- the first use of a vehicle-in-the-loop simulator for this kind of problem. Fayazi drove his real car at the International Transportation Innovation Center in Greenville, South Carolina, where a geofenced area was set up to use as the simulated intersection. Using GPS sensors, his car was just as visible to the intersection controller as the virtual autonomous vehicles that were also populating its memory banks. Ideally, Fayazi says he'd like to have tested it with an autonomous vehicle, but they are hard to come by, particularly in South Carolina. Instead, the intersection controller directly governed his speed in the study (as it did with the simulated vehicles), and this controller sent him a speed to maintain in order to safely cross the junction. Over the course of an hour, the intelligent intersection only required 11 vehicles to come to a complete halt. By contrast, when the simulation was run with a traffic light instead, more than 1,100 vehicles had to stop at the junction over the course of an hour.

Older age at menopause and use of hormone therapy produce increased risk of hearing loss

Science Daily - Wed, 10/05/2017 - 11:55am
It has long been suspected that menopause and the use of hormones had a direct effect on hearing. However, findings from previous studies have been conflicting, with some suggesting that hearing worsens at menopause but that there is benefit with hormone therapy (HT). Now results from the first large population study conducted to assess the association show that older age at natural menopause and the use of oral HT are each associated with a higher risk of hearing loss.

Scientists print nanoscale imaging probe onto tip of optical fiber

Science Daily - Wed, 10/05/2017 - 11:55am
A team of researchers has developed a way to print a nanoscale imaging probe onto the tip of a glass fiber as thin as a human hair, accelerating the production of the promising new device from several per month to several per day. The high-throughput fabrication technique opens the door for the widespread adoption of this and other nano-optical structures, which squeeze and manipulate light in ways that are unachievable by conventional optics.

Qualcomm Announces New Snapdragon 630, 660 Midrange Chips

Slashdot - Wed, 10/05/2017 - 10:00am
An anonymous reader quotes a report from ExtremeTech: Qualcomm's new upper-midrange and midrange Snapdragon 600 refreshes were announced today, and both parts are a solid improvement over their predecessors. Both the Snapdragon 630 and 660 are being upgraded with the X12 LTE modem that debuted with the Snapdragon 820 last year. You don't need to sweat the technical details too much on this -- the bottom line is that the newer modem is capable of up to 600Mbps downstream and 150Mbps upstream connectivity. The new Snapdragon 660 SoC is also an eight-core chip, with four Kryo CPU cores clocked at 2.2GHz, and four clocked at 1.8GHz. Total memory bandwidth is 29.9GBps, nearly double what the Snapdragon 650, 652, and 653 offered. Technologies like QuickCharge 4 and a Spectra 160 ISP round out the chip. The Spectra 160 ISP isn't quite as powerful as the Spectra 180 ISP in the Snapdragon 835, but it's still a capable processor in its own right. Overall, the Snapdragon 660 should be considered the upper-midrange SoC with some capabilities and features that bleed over from the high-end 8xx family. The degree to which users notice the difference between a high-end 6xx and the 8xx series will depend on how aggressively they use their phones. Meanwhile, the Snapdragon 630 is intended as a midrange, workhorse part with strong battery life and good (if not stunning) overall performance. This new SoC combines four Cortex-A53 cores (clocked at 2.2GHz) with four high-efficiency Cortex-A53 cores running at 1.8GHz. GPU performance is provided by the Adreno 508 (likely just a clock-bumped Adreno 506) and overall memory bandwidth is just 10.66GBps. This still represents a significant improvement over previous devices, but the Snapdragon 630 won't break speed records.
