High-tech archaeologist uses radar, thermal-imagery, & UAV’s to explore sacred sites

Many Mongolians consider the tomb (of Genghis Khan) an extremely sacred place and believe any desecration of it could trigger a curse that would end the world.

“Using traditional archeological methods would be disrespectful to believers,” Albert Yu-Min Lin says. “The ability to explore in a noninvasive way lets us try to solve this ancient secret without overstepping cultural barriers.

Lin investigates sites with a high-tech tool kit that leverages photographs taken firsthand on the ground, images gathered from satellites and unmanned aircraft, GPS tracks from expeditions, and geophysical instruments. “There are many ways to look under the ground without having to touch it,” he observes. Thermal-imaging systems show what lies below by detecting heat signals and patterns emitted from the Earth. Magnetometry uses the Earth’s magnetic field to pinpoint subterranean clues as microscopic as bacteria in decaying wood. Ground-penetrating radar bounces back images revealing subsurface objects or disturbances. Tiny remote wireless sensors collect data from places no human can go.

“These new approaches could benefit all kinds of projects, from gaining a whole new view of regions like Mongolia to tracking animal migrations to mapping the brain,” notes Lin. “The real trick is synthesizing the vast amounts of information we collect into something that can be understood. My colleagues and I use visualization techniques to sort, relate, and cross-link billions of individual data bits. We program it all into a file that allows us to re-render it into a digital 3-D world.”

Ring of Fire Derecho – travelled 600 miles from Iowa to D.C.

On Friday, a historic, record-setting heat wave covered a sprawling region from the Midwest to the Southeast. All-time high temperatures records of 109 were established in Nashville and Columbia, South, Carolina and tied in Raleigh and Charlotte which hit 105 and 104. Here in Washington, D.C., the mercury climbed to an astonishing 104 degrees (breaking the previous record set in 1874 and 2011 by two degrees), our hottest June day in 142 years of records.

 

 

…the coverage and availability of this heat energy was vast, sustaining the storms on their 600 mile northwest to southeast traverse. The storms continually ingested the hot, humid air and expelled it in violent downdrafts – crashing into the ground at high speeds and spreading out, sometimes accelerating further.

Peak wind gusts in the D.C. region include the following:

71 mph near Dulles Airport
70 mph in Damascus, Md.
79 mph in Reston, Va.
65 mph in Rockville, Md.
70 mph at Reagan National Airport
76 mph in Seat Pleasant, Md. (Prince George’s co.)
77 mph in Swan Point, Md. (Charles co.)
70 mph in Ashburn, Va.
69 mph in Leesburg, Va.

In addition, an 80 mph gust was clocked in Fredericksburg. To the north and west, 91 mph and 72 mph gusts were measured in Ft. Wayne, Indiana and Columbus, Ohio

U.S. Air Force places overpowering jet armada near Iran

The U.S. Air Force is quietly assembling the world’s most powerful air-to-air fighting team at bases near Iran. Stealthy F-22 Raptors on their first front-line deployment have joined a potent mix of active-duty and Air National Guard F-15 Eagles, including some fitted with the latest advanced radars. The Raptor-Eagle team has been honing special tactics for clearing the air of Iranian fighters in the event of war.

The highly-experienced Massachusetts Guardsmen, who typically have several years more experience than their active-duty counterparts, would be ready “should Iran test the 104th,” said wing commander Col. Robert Brooks.

…it’s the methods above that the U.S. dogfighting armada would likely use to wipe out the antiquated but determined Iranian air force if the unthinkable occurred and fighting broke out. The warplanes are in place. The pilots are ready. Hopefully they won’t be needed.

Cadillac releases sophisticated array of semi-autonomous sensors for self-driving cars

Google isn’t the only company working on a self-driving car. Cadillac today announced that it is actively road testing a semi-autonomous system called Super Cruise that can control a vehicle’s steering, braking and lane-centering capabilities. Super Cruise, according to Cadillac, is designed to help make freeway driving easier on the driver when either stuck in traffic or during long hauls down the interstate.

The system works by combining on-board radar, ultrasonic sensors, cameras and GPS data to give your car the ability to read lane markings and detect curves in the roadway.

For certain luxury cars, we are already half-way (or more) there. From the Cadillac news release:

Many of the building block technologies for Super Cruise are already available on the all-new 2013 Cadillac XTS and ATS luxury sedans, as part of the available Driver Assist Package:

  • Rear Automatic Braking
  • Full-Speed Range Adaptive Cruise Control
  • Intelligent Brake Assist
  • Forward Collision Alert
  • Safety Alert Seat
  • Automatic Collision Preparation
  • Lane Departure Warning
  • Side Blind Zone Alert
  • Rear Cross Traffic Alert
  • Adaptive Forward Lighting
  • Rear Vision Camera With Dynamic Guidelines
  • Head Up Display

The key to delivering semi-autonomous capability will be the integration of lane-centering technology that relies on forward-looking cameras to detect lane markings and GPS map data to detect curves and other road characteristics, said John Capp, General Motors director of Global Active Safety Electronics and Innovation.

 

 

Pretty crazy to think about all the technology needed to self drive a car. That’s 12 sensors/alerts/displays with more needed to fully automate the simplest of driving tasks. Makes our brains seem pretty sophisticated.

White House names the next CTO of the United States – an “entrepreneur in residence”

Todd Park has been named the next U.S. Chief Technology Officer by the White House.

A profile of him in O’Reilly Radar written by Alex Howard:

Park has been working to revolutionize the healthcare industry at HHS since 2009, and in the private sector as an entrepreneur since 1997. Now he’ll have the opportunity to try to improve how the entire federal government works through technology. It’s a daunting challenge, but one that he may have been born to take on. Park is charismatic, understands technology on a systems level, and has been successful in applying open innovation and a lean startup approach to government at HHS.

It’s extremely exciting to hear that HHS’s “entrepreneur in residence” is moving into a much bigger stage.

On a 30,000-foot level, his personal story is deeply compelling. He’s the son of a brilliant immigrant who came here from Korea, attained a graduate-level education, spent his career in a company in the United States and raised a family, including a son who then went on to live the American dream.
