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.
When President Obama left, I stayed on at the National Security Council in order to serve my country. I lasted eight days.
In 2011, I was hired, straight out of college, to work at the White House and eventually the National Security Council. My job there was to promote and protect the best of what my country stands for. I am a hijab-wearing Muslim woman––I was the only hijabi in the West Wing––and the Obama administration always made me feel welcome and included.
Like most of my fellow American Muslims, I spent much of 2016 watching with consternation as Donald Trump vilified our community. Despite this––or because of it––I thought I should try to stay on the NSC staff during the Trump Administration, in order to give the new president and his aides a more nuanced view of Islam, and of America's Muslim citizens.
Long after research contradicts common medical practices, patients continue to demand them and physicians continue to deliver. The result is an epidemic of unnecessary and unhelpful treatments.
First, listen to the story with the happy ending: At 61, the executive was in excellent health. His blood pressure was a bit high, but everything else looked good, and he exercised regularly. Then he had a scare. He went for a brisk post-lunch walk on a cool winter day, and his chest began to hurt. Back inside his office, he sat down, and the pain disappeared as quickly as it had come.
That night, he thought more about it: middle-aged man, high blood pressure, stressful job, chest discomfort. The next day, he went to a local emergency department. Doctors determined that the man had not suffered a heart attack and that the electrical activity of his heart was completely normal. All signs suggested that the executive had stable angina—chest pain that occurs when the heart muscle is getting less blood-borne oxygen than it needs, often because an artery is partially blocked.
“No… it’s a magic potty,” my daughter used to lament, age 3 or so, before refusing to use a public restroom stall with an automatic-flush toilet. As a small person, she was accustomed to the infrared sensor detecting erratic motion at the top of her head and violently flushing beneath her. Better, in her mind, just to delay relief than to subject herself to the magic potty’s dark dealings.
It’s hardly just a problem for small people. What adult hasn’t suffered the pneumatic public toilet’s whirlwind underneath them? Or again when attempting to exit the stall? So many ordinary objects and experiences have become technologized—made dependent on computers, sensors, and other apparatuses meant to improve them—that they have also ceased to work in their usual manner. It’s common to think of such defects as matters of bad design. That’s true, in part. But technology is also more precarious than it once was. Unstable, and unpredictable. At least from the perspective of human users. From the vantage point of technology, if it can be said to have a vantage point, it's evolving separately from human use.
Tucker Carlson’s latest reinvention is guided by a simple principle—a staunch aversion to whatever his right-minded neighbors believe.
Tucker Carlson is selling me hard on the swamp. It is an unseasonably warm afternoon in late January, and we are seated at a corner table in Monocle, an upscale Capitol Hill eatery frequented by the Fox News star. (Carlson, who typically skips breakfast and spends dinnertime on the air, is a fan of the long, luxurious, multi-course lunch, and when I requested an interview he proposed we do it here.) As we scan the menus, I mention that I’ll be moving soon to the Washington area, and he promptly launches into an enthusiastic recitation of the district’s many virtues and amenities.
“I’m so pathetically eager for people to love D.C.,” he admits. “It’s so sad. It’s like I work for the chamber of commerce or something.”
A new report explores why those who benefitted from Obamacare’s Medicaid expansion supported the man who promised to reverse it.
Here’s a question that’s baffled health reporters in the months since the election: Why would people who benefit from Obamacare in general—and its Medicaid expansion specifically—vote for a man who vowed to destroy it?
Some anecdotal reports have suggested that people simply didn’t understand that the benefits they received were a result of the Affordable Care Act. That was the case for one Indiana family The New York Times described in December:
Medicaid has paid for virtually all of his cancer care, including a one-week hospitalization after the diagnosis, months of chemotherapy, and frequent scans and blood tests.
But Mr. Kloski and his mother, Renee Epperson, are still not fans of the health law over all. They believed that it required that Mr. Kloski be dropped, when he turned 26, from the health plan his mother has through her job at Target — not understanding that it was the law that kept him on the plan until he was 26.
The polymath computer scientist David Gelernter’s wide-ranging ideas about American life.
Last month, David Gelernter, the pioneering Yale University computer scientist, met with Donald Trump to discuss the possibility of joining the White House staff. An article about the meeting in TheWashington Post was headlined, “David Gelernter, fiercely anti-intellectual computer scientist, is being eyed for Trump’s science adviser.”
It is hard to imagine a more misleading treatment.
By one common definition, anti-intellectualism is “hostility towards and mistrust of intellect, intellectuals, and intellectual pursuits, usually expressed as the derision of education, philosophy, literature, art, and science, as impractical and contemptible.”
Here is the exchange that I had with Gelernter when I reached out to ask if he would be interested in discussing the substance of his views on science, politics and culture.
In response, some GOP members of Congress are attempting to show sympathy for voter concerns.
In their districts this week, Republican members of Congress are facing pushback from angry town-hall crowds over the potential repeal of the Affordable Care Act. Some lawmakers are offering up a degree of sympathy in response, whether by defending the right to protest or attempting to convince voters they understand their concerns.
Republican Senator Tom Cotton told an agitated town hall audience in Arkansas on Wednesday that he wouldn’t deny that “Obamacare has helped many Arkansans,” after a woman said the law saved her life. When another woman insisted she wasn’t a “paid protester,” the senator tried to reassure the crowd that wasn’t a charge he planned to make: “You’re all Arkansans and I’m glad to hear from you,” he said. “Thank you to everyone for coming out tonight, whether you agree with me or disagree with me. This is part of what our country is all about.”
Liberals may need to decide whether to focus on energizing their base or expanding their coalition.
Democratic Senator Claire McCaskill, who is up for reelection in the red state of Missouri in 2018, recently told a St. Louis radio host she may face a primary challenge. “I may have a primary because there is, in our party now, some of the same kind of enthusiasm at the base that the Republican Party had with the Tea Party,” she said during an interview earlier this month. “Many of those people are very impatient with me because they don’t think I’m pure,” she added.
As the Democratic Party contemplates what’s next in the wake of its defeat in the presidential election, liberals may have to decide what matters more: Building a big tent party where far-left voters and moderate centrists can co-exist even if they occasionally disagree on policy and strategy, or focusing on the demands of the party’s progressive base, potentially creating a more like-minded and ideologically rigid coalition in the process.
All in all, the United States has already set more than 2,800 new record high temperatures this month. It has only set 27 record lows.
Most people handle this weather as the gift it is: an opportunity to get outside, run or bike or play catch, and get an early jump on the spring. But for the two-thirds of Americans who are at least fairly worried about global warming, the weather can also prompt anxiety and unease. As one woman told the Chicago Tribune: “It’s scary, that’s my first thing. Because in all my life I’ve never seen a February this warm.” Or as one viral tweet put it:
High-school textbooks too often gloss over the American government’s oppression of racial minorities.
Earlier this month, McGraw Hill found itself at the center of some rather embarrassing press after a photo showing a page from one of its high-school world-geography textbooks was disseminated on social media. The page features a seemingly innocuous polychromatic map of the United States, broken up into thousands of counties, as part of a lesson on the country’s immigration patterns: Different colors correspond with various ancestral groups, and the color assigned to each county indicates its largest ethnic representation. The page is scarce on words aside from an introductory summary and three text bubbles explaining specific trends—for example, that Mexico accounts for the largest share of U.S. immigrants today.
