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.
Freddie Gray's death on April 19 leaves many unanswered questions. But it is clear that when Gray was arrested in West Baltimore on the morning of April 12, he was struggling to walk. By the time he arrived at the police station a half hour later, he was unable to breathe or talk, suffering from wounds that would kill him.*
Gray died Sunday from spinal injuries. Baltimore authorities say they're investigating how the 25-year-old was hurt—a somewhat perverse notion, given that it was while he was in police custody, and hidden from public view, that he apparently suffered injury. How it happened remains unknown. It's even difficult to understand why officers arrested Gray in the first place. But with protestors taking to the streets of Baltimore since Gray's death on Sunday, the incident falls into a line of highly publicized, fatal encounters between black men and the police. Meanwhile, on Tuesday, a reserve sheriff's deputy in Tulsa, Oklahoma, pleaded not guilty to a second-degree manslaughter charge in the death of a man he shot. The deputy says the shooting happened while he was trying to tase the man. Black men dying at the hands of the police is of course nothing new, but the nation is now paying attention and getting outraged.
After a five-month delay, Loretta Lynch made history last week. On Thursday, the Senate confirmed Lynch as the next U.S. attorney general, the first African American woman ever to hold this Cabinet position. Her long-stalled nomination sometimes seemed in doubt, held hostage to partisan jockeying between Democrats and Republicans. But one political bloc never gave up, relentlessly rallying its support behind Lynch: the black sorority.
During her initial hearing, the seats behind Lynch were filled with more than two dozen of her Delta Sigma Theta Sorority sisters arrayed in crimson-and-cream blazers and blouses, ensuring their visibility on the national stage. These Delta women—U.S. Representatives Marcia Fudge and Joyce Beatty among them—were there to lend moral support and show the committee that they meant business. The Deltas were not alone. The Lynch nomination also drew support from congressional representatives from other black sororities: Alpha Kappa Alpha members Terri Sewell and Sheila Jackson Lee took to the House floor to advocate for a vote while Sigma Gamma Rho members Corinne Brown and Robin Kelly and Zeta Phi Beta member Donna Edwards used social media and press conferences to campaign on Lynch’s behalf.
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.
I’m not a dog person. I prefer cats. Cats make you work to have a relationship with them, and I like that. But I have adopted several dogs, caving in to pressure from my kids. The first was Teddy, a rottweiler-chow mix whose bushy hair was cut into a lion mane. Kids loved him, and he grew on me, too. Teddy was probably ten years when we adopted him. Five years later he had multiple organs failing and it was time to put him to sleep.
When I arrived at the vet, he said I could drop him off. I was aghast. No. I needed to stay with Teddy.As the vet prepped the syringe to put him to sleep, I started sobbing. The vet gave me a couple minutes to collect myself and say goodbye. I held Teddy's paw until he died. Honestly, I didn't think I was that attached.
Four hours after learning about Saturday's devastating earthquake in Nepal, I received a Facebook notification I had never seen before: Sonia, a journalist friend based in northern India, was "marked safe." An hour later, the same notification about a different friend popped up. Then another. Soon, several of my friends wrote that they, too, had learned via this strange new notification that their friends in Nepal were okay.
A few hours later, the mystery was solved. On Saturday afternoon, Facebook CEO Mark Zuckerberg announced on his timeline that the notifications came from Safety Check, a service the company launched last fall. "When disasters happen, people need to know their loved ones are safe," he wrote, "It's moments like this that being able to connect really matters."
A magnitude 7.8 earthquake struck Nepal early on Saturday, centered 10 miles below the surface, less than 50 miles from the capital of Kathmandu. At least 2,200 are already reported to have been killed by the quake and subsequent avalanches triggered in the Himalayas. Historic buildings and temples were destroyed, leaving massive piles of debris in streets as rescue workers and neighbors work to find and help those still trapped beneath rubble. Below are images from the region of the immediate aftermath of one of the most powerful earthquakes to strike Nepal in decades. (Editor's note, some of the images are graphic in nature.)
In her new book No One Understands You and What To Do About It, Heidi Grant Halvorson tells readers a story about her friend, Tim. When Tim started a new job as a manager, one of his top priorities was communicating to his team that he valued each member’s input. So at team meetings, as each member spoke up about whatever project they were working on, Tim made sure he put on his “active-listening face” to signal that he cared about what each person was saying.
But after meeting with him a few times, Tim’s team got a very different message from the one he intended to send. “After a few weeks of meetings,” Halvorson explains, “one team member finally summoned up the courage to ask him the question that had been on everyone’s mind.” That question was: “Tim, are you angry with us right now?” When Tim explained that he wasn’t at all angry—that he was just putting on his “active-listening face”—his colleague gently explained that his active-listening face looked a lot like his angry face.
“People skills” are almost always assumed to be a good thing. Search employment ads and you will find them listed as a qualification for a startling array of jobs, including Applebee’s host, weight-loss specialist, CEO, shoe salesperson, and (no joke) animal-care coordinator. The notion that people smarts might help you succeed got a boost a quarter century ago, when the phrase emotional intelligence, or EI, entered the mainstream. Coined in a 1990 study, the term was popularized by Daniel Goleman’s 1995 book . Since then, scores of researchers have shown how being in touch with feelings—both your own and other people’s—gives you an edge: compared with people who have average EI, those with high EI do better at work, have fewer health problems,and report greater life satisfaction.
Today was the latest installment of the never-ending Clinton scandal saga, but it won’t be the last. Yet in some ways, the specifics are a distraction. The sale of access was designed into the post-2001 Clinton family finances from the start. Probably nobody will ever prove that this quid led to that quo … but there’s about a quarter-billion-dollar of quid heaped in plain sight and an equally impressive pile of quo, and it’s all been visible for years to anyone who cared to notice. As Jonathan Chait, who is no right-wing noise-machine operator, complained: “The Clintons have been disorganized and greedy.”
“All of this amounts to diddly-squat,” pronounced long-time Clinton associate James Carville when news broke that Hillary Clinton had erased huge numbers of emails. That may not be true: If any of the conduct in question proves illegal, destroying relevant records may also have run afoul of the law.
In Baltimore, where 25-year-old Freddie Gray died shortly after being taken into police custody, an investigation may uncover homicidal misconduct by law enforcement, as happened in the North Charleston, South Carolina, killing of Walter Scott. Or the facts may confound the darkest suspicions of protestors, as when the Department of Justice released its report on the killing of Michael Brown.
What's crucial to understand, as Baltimore residents take to the streets in long-simmering frustration, is that their general grievances are valid regardless of how this case plays out. For as in Ferguson, where residents suffered through years of misconduct so egregious that most Americans could scarcely conceive of what was going on, the people of Baltimore are policed by an entity that perpetrates stunning abuses. The difference is that this time we needn't wait for a DOJ report to tell us so. Harrowing evidence has been presented. Yet America hasn't looked.
