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.
Just why was Tom Hanks dancing in a black-and-orange suit on Saturday Night Live so funny?
This weekend’s episode of Saturday Night Live offered a mini masterpiece: a gloriously silly Halloween-themed piece revolving around a “Haunted Elevator” ride and its unusual star attraction. Beck Bennett and Kate McKinnon played a couple looking for spooky thrills who instead found something far more bewildering: a pumpkin-suited man who would randomly appear alongside two cheerful skeletons and perform a dance routine. “Who are you?” asked a frustrated Bennett after the man (played by Tom Hanks) appeared for the second time. “I’m David Pumpkins!” came the reply.
McKinnon followed up: “Yeah, and David Pumpkins is … ?”
Tom Hanks’s Doug has a lot in common with “Black Jeopardy” contestants—except, of course, for politics.
SNL’s ongoing “Black Jeopardy” series has been, in part, about divisions. In each edition, black American contestants answer Kenan Thompson’s clues with in-jokes, slang, and their shared opinions while an outsider—say, Elizabeth Banks as the living incarnation of Becky, Louis C.K. as a BYU African American Studies professor, or Drake as a black Canadian—just show their cluelessness.
When Tom Hanks showed up in a “Make America Great Again” hat and bald-eagle shirt to play the contestant “Doug” this weekend, it seemed like the set-up for the ugliest culture clash yet. The 2016 election has been a reminder of the country’s profound racial fault lines, and SNL hasn’t exactly been forgiving toward the Republican nominee on that front: Its version of Trump hasn’t been able to tell black people apart, and it aired a mock ad painting his supporters as white supremacists—which, inarguably, some of them really are.
In the 1970s, a new wave of post-Watergate liberals stopped fighting monopoly power. The result is an increasingly dangerous political system.
It was January 1975, and the Watergate Babies had arrived in Washington looking for blood. The Watergate Babies—as the recently elected Democratic congressmen were known—were young, idealistic liberals who had been swept into office on a promise to clean up government, end the war in Vietnam, and rid the nation’s capital of the kind of corruption and dirty politics the Nixon White House had wrought. Richard Nixon himself had resigned just a few months earlier in August. But the Watergate Babies didn’t just campaign against Nixon; they took on the Democratic establishment, too. Newly elected Representative George Miller of California, then just 29 years old, announced, “We came here to take the Bastille.”
Biology textbooks tell us that lichens are alliances between two organisms—a fungus and an alga. They are wrong.
In 1995, if you had told Toby Spribille that he’d eventually overthrow a scientific idea that’s been the stuff of textbooks for 150 years, he would have laughed at you. Back then, his life seemed constrained to a very different path. He was raised in a Montana trailer park, and home-schooled by what he now describes as a “fundamentalist cult.” At a young age, he fell in love with science, but had no way of feeding that love. He longed to break away from his roots and get a proper education.
At 19, he got a job at a local forestry service. Within a few years, he had earned enough to leave home. His meager savings and non-existent grades meant that no American university would take him, so Spribille looked to Europe.
Trump supporters are convinced Democrats are using “oversampling” to stuff the polls in Hillary Clinton’s favor. But they’re just wrong about statistics.
Late last night, pro-Trump Twitter lit up with excited chatter. Donald Trump is falling fast in the polls, sliding through a month-long decline most statisticians would say is a result of him being, you know, unpopular. (And maybe this. Or this. Or this.) But one blogger had another theory: Polling organizations are deliberately interviewing more Democrats to skew the surveys toward Hillary Clinton.
This afternoon, Trump threw his support behind the idea. “When the polls are even, when they leave them alone and do them properly, I’m leading,” he said at a rally in Florida. “But you see these polls where they’re polling Democrats. How’s Trump doing? Oh, he’s down. They’re polling Democrats. The system is corrupt and it’s rigged and it’s broken.”
What use is there today for one of the oldest virtues?
As many Americans go about their days, I imagine they have two little angels perched on their shoulders, whispering conflicting messages about happiness and material wealth. One angel is embodied by James Altucher, a minimalist self-help guru recently profiled by The New York Times. Altucher claims to have only 15 possessions, after having unburdened himself a few months ago of 40 garbage bags’ worth of stuff and never looking back. As I read about Altucher, I rolled the numbers 15 and 40 over in my mind, thinking about the belongings in my bedroom and the garbage bags under my kitchen sink.
The other angel is Tyler Brûlé, the editor in chief of the fantastically high-end lifestyle magazine Monocle and a columnist for the Financial Times. He is the sort of writer who tosses off such lines as “I zipped along the autostrada through the Val d’Aosta with the ever-trusty Mario (my Italian driver for the past 20 years) at the wheel” with little regard for how privileged and pretentious he sounds (especially in his superfluous parentheticals). Still, there is something, I’m a little ashamed to say, that I envy about Brûlé’s effortless cosmopolitanism—which, it’s hard to miss, is only made possible by unusual wealth.
As I’ve written, one way some men are responding to their slipping place in the social hierarchy is by supporting Donald Trump, whose rhetoric hearkens to a less progressive, more traditional time.
But another way men react to having their masculinity threatened is stealthier. They do fewer chores, according to an analysis by Dan Cassino, a professor at Fairleigh Dickinson University, and his wife Yasemin Besen-Cassino, from Montclair State University, which relied on the American Time Use Study. According to their findings, men especially avoid housework just when you’d think they would pick up the slack: When they make less than their wives do.
Answering a common question from a polarizing election cycle
Our major party candidates have historically high disapproval ratings. So I am often asked, usually by people in “blue” enclaves, “How can anyone vote for him?” and by people in “red” enclaves, “How can anyone vote for her?” Since I live in coastal California, and because so many more Americans presently intend to vote for Hillary Clinton, rather than Donald Trump, who is disapproved of by significantly more people, I hear “how can anyone vote Trump” more than the reverse.
And I myself could never vote Trump, so I get the confusion on some level––I might even share it if I hadn’t spent time with so many Trump supporters who are good people, not “deplorables” (though there is a faction of deplorable Trump supporters). Still, the answer I’ve started giving Clinton voters is probably as effective for similarly confounded Trump supporters. Without further ado, here it is:
By ridiculing Kid Cudi’s substance use and depression, he proves how much guts his rival had in fighting stigmas.
When the rapper Kid Cudi announced he’d checked himself into rehab for depression and suicidal thoughts earlier this month, it sparked a social-media conversation about stigmas around mental illness in America generally, and among black men specifically. The hashtag #YouGoodMan went viral, people shared their favorite hip-hop songs about mental health, and many praised Cudi for his courage in going public.
Now, a new track from Drake makes clear how powerful the stigma Cudi defied remains. In “Two Birds, One Stone,” the rapper seems to describe Cudi, saying,
You were the man on the moon
Now you just go through your phases
Life of the angry and famous
Rap like I know I'm the greatest
Then give you the tropical flavors
Still never been on hiatus
You stay xanned and perked up
So when reality set in you don’t gotta face it
