That's the argument made by computer scientists M.P.Sivaram Kumar and S. Rajasekaran in a recent article in the Journal of Computing entitled "Path Planning Algorithm for Extinguishing
Forest Fires." Their thesis is simple: the vast majority of forests are destroyed by wild forest fires, and current methods of sylvan vigilance -- mainly those involved individual personnel on foot patrol -- are grossly inefficient in identifying emerging threats. Their pre-defined route may be damaged or obscured, inclement weather affects visibility, and life on patrol is boring and "miserable," leading to a lack of attention.
Kumar and Rajasekaran argue that deploying robotic systems throughout wooded areas will increase firefighters' ability not just to identify emerging threats, but also to more effectively plot the path of a wildfire, and then deploy the appropriate resources to the right places. The two imagine a grid-based system of automated drones, designed to detect abnormal changes in temperature and relay data back to a command center:
The automatic forest fire detection and extinguishing system consists of
nodes deployed deterministically in a forest area and all
the nodes know their location based on coordinate values
of a matrix. Each node is equipped with a temperature
sensor and an Omni directional antenna. Nodes continuously monitor the environment to check if there is fire or
not in the particular cell. When change in temperature i.e.
temperature raises above a certain threshold, is detected
by a particular node they send message packets which
contain location measurements. These packets are received by one of the corner node. The corner node then
sends the packet to the Actor which in turn will process
the packet which can be used in reaching the target area
to extinguish fire.
On-the-ground nodes, they argue, are significantly better than the preexisting satellite detection systems that, due to a long scan period and low resolution of images, end up detecting fires relatively late. Relying on satellites often means that firefighting personnel deploy more resources in their firefighting than would otherwise be necessary.
There are obvious environmental concerns to stringing a sprawling forest with robotic nodes. Introducing any man-made object, even stationary a drone, can have unintended consequences on a complex arboreal ecosystem. Unexpected costs -- a tree falling in the woods, surprise visits from assorted large mammals -- could make deploying and maintaining a robotic grids prohibitively expensive.
But among the significant additional benefits: potentially saving lives. Wireless Emergency Alerts (WEA), a system developed by FEMA, the FCC, and wireless carriers, will soon be deployed in emergency situations like severe weather to notify citizens of imminent threats to their safety. Within the next few weeks, nearly everyone in the country with a mobile phone could start receiving text messages from the National Weather Service, local law enforcement, or perhaps even the President. Here's how it works:
In the event of an emergency, an authorized alerting agency can select a cell tower (or towers) to broadcast a WEA. In order to receive the message, a person must be within range of the cell-tower broadcast, and must have a phone capable of "hearing" the the broadcast. Most cellular devices manufactured after mid-2011 already have this capability.
It is through the use of CB technology that CMAS is able to provide some geographic targeting without the need for opting-in. However, it is important to note that because WEAs are "broadcast" from towers, the geo-targeting feature is not as precise as GPS. GPS is a two-way street of communication between a GPS-equipped device and various positioning satellites. WEAs are not two-way...it is simply a modern day "shout" to give a heads-up that something requires your attention.
According to the National Fire Protection Association, only 11 people were killed in wildfire-related incidents in 2011. But application of the sensor technology to, say, rivers with a high likelihood of flooding, earthquake-prone regions, and other unstable natural centers could give first responders a useful heads-up. When tied in with FEMA's new WEA system, average citizens could have enough advance warning of danger to protect themselves in the event of a natural disaster. And in the event of a fast-moving fire or flood, a few extra minutes could mean the difference between life and death.
Two recent events—the spectacle of Garry Trudeau, the Doonesbury creator, attacking a group of murdered cartoonists for offending his sensibilities, and the protest organized by a group of bien-pensant writers against the PEN American Center for planning to honor those cartoonists tonight in New York—has brought the Charlie Hebdo controversy back to public consciousness. So has the failed attack Sunday in Texas on a group of anti-Islam militants staging a Prophet Muhammad cartoon contest, though, unlike Charlie Hebdo, the organization that sponsored the Texas event is run by an actual anti-Muslim extremist who, I'm proud to say, is a personal nemesis of mine.
Much has already been written about both the Trudeau and PEN controversies. I particularly recommend David Frum on Trudeau, and Katha Pollitt and Matt Welch on PEN, as well as this fine op-ed by Andrew Solomon and Suzanne Nossel, the president and executive director, respectively, of the PEN American Center. These represent only a handful of the many dozens of writers who have risen in defense of free speech, and of Charlie Hebdo’s right to lampoon religion.
The Onion had a problem: It fell behind the times. The mock newspaper hadn’t printed an issue on actual paper since 2013, and in the period since, it never redesigned its website. As the media world changed—as the New York Times and the Washington Post adapted the ways they published stories online—The Onion lost a key satirical weapon. Visually, it no longer looked like many of the publications it parodied. And so, like it had done many times before, The Onion tagged along.
I recently spoke with Pugh about what this means for American workers, society, and public policy. A lightly edited transcript of our conversation follows.
Rebecca J. Rosen: A central premise of your research is that work is about more than money—it's also about identity and relationships, particularly within a family. How does work shape us beyond our bank accounts?
The man from Hope is back. Nope, not that one—the one whose wife is leading the Democratic field. The one who succeeded him as governor of Arkansas: Republican Mike Huckabee.
Huckabee is announcing Tuesday that he's a candidate for president with a kickoff in the hometown he shares with Bill Clinton. After a strong run in 2008 and a decision to take the 2012 cycle off, Huckabee is testing whether he still has the same pull he once did.
He's the third Republican candidate to announce this week alone, and the fourth in 10 days. On Monday, neurosurgeon Ben Carson and tech executive Carly Fiorina both announced campaigns, and last week Senator Bernie Sanders announced he was seeking the Democratic nomination.
In a story about the origins of confessional apps like Whisper and the now-defunct Secret, I recently mentionedThe Athenian Mercury, a British periodical of the 1690s that is widely credited with inventing the modern advice column. "I would honestly love to read a compilation of questions & answers from the Athenian Mercury," somebody wrote in the comment section of that story. To which I say: Me too!
Perusing these inquiries feels a little bit like wading through fields of Google auto-complete. There's something satisfying (and, okay, a little voyeuristic) about knowing the questions tugging at another person's mind. And while contemporary advice columns have a reputation for being pretty narrowly self-concerned—people often ask what to do about specific, personal problems—The Athenian Mercury dealt mostly (though not exclusively) with big, existential questions. Or, as Josh Sternberg wrote to me on Twitter, "17th-century people had a different definition of 'advice;' they were a contemplative people on the cusp of enlightenment."
Last year, as part vanity project, part science experiment, I decided to adopt a new skin-care routine, something that an aging celebrity might use on a daily basis. My goal was to determine whether, in fact, a high-tech routine can make a difference. Are beauty products worth it?
A dermatologist friend introduced me to Marie, who ran a “skin science” clinic next to his office in Calgary, Canada. This was not a medical office, but a clinic that provided cosmetic services and products aimed at helping people enhance the look and condition of their skin. “I am, really, a skin coach,” Marie told me as she showed me around the office. She had a degree in microbiology, was infectiously good-natured, and had absolutely flawless skin.
Where did it come from, and what are its intentions? The simplicity of these questions can be deceiving, and few Western leaders seem to know the answers. In December, The New York Times published confidential comments by Major General Michael K. Nagata, the Special Operations commander for the United States in the Middle East, admitting that he had hardly begun figuring out the Islamic State’s appeal. “We have not defeated the idea,” he said. “We do not even understand the idea.” In the past year, President Obama has referred to the Islamic State, variously, as “not Islamic” and as al-Qaeda’s “jayvee team,” statements that reflected confusion about the group, and may have contributed to significant strategic errors.
Sullivan: Now we’re getting somewhere. And I’m not just referring to all of the potential wars that so many of our Game of Thrones characters are trying to either stave off or set aflame. We’ll get to those in a moment. No, I’m talking about the long-simmering question that should be on every fan’s mind, the one that showrunners David Benioff and D.B. Weiss had to answer before George R. R. Martin would hand over his series so they could bring it to television
Texas has the rare distinction among U.S. states of having been, for a decade in the 19th century, its own nation. That history of independence, that lingering pride of sovereignty, has never really left the state, and every so often it arouses a certain suspicion of outside forces—be it Mexicans, ISIS fighters, or most frequently, the federal government. So when the U.S. military announced plans to hold an eight-week joint exercise it called Operation Jade Helm 15 in Texas and five other western states this summer, the people of Bastrop County quickly—and with the help of radio host Alex Jones and Infowars.com—saw it for what it really was: a preparation for the military to impose martial law in the Lone Star State.
