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.
As the moderator notes, Christie's campaign has been attacking Rubio for his no-exceptions stance on abortion. It's an oddity of the center-right electorate in New Hampshire that one Republican can attack another for being too conservative on social issues.
My view on the Hillary Clinton email “scandal,” as expressed over the months and also yesterday, is that this is another Whitewater. By which I mean: that the political and press hubbub, led in each case on the press’s side by the New York Times, bears very little relationship to the asserted underlying offense, and that after a while it’s hard for anyone to explain what the original sin / crime / violation was in the first place.
The Whitewater investigation machine eventually led, through a series of Rube Goldberg / Jorge Luis Borges-style weirdnesses, to the impeachment of Bill Clinton, even though the final case for removing him from office had exactly nothing to do with the original Whitewater complaint. Thus it stands as an example of how scandals can take on a zombie existence of their own, and of the damage they can do. The Hillary Clinton email “scandal” has seemed another such case to me, as Trey Gowdy’s committee unintentionally demonstrated with its 11-hour attempted takedown of Clinton last year.
Hillary Clinton’s realistic attitude is the only thing that can effect change in today’s political climate.
Bernie Sanders and Ted Cruz have something in common. Both have an electoral strategy predicated on the ability of a purist candidate to revolutionize the electorate—bringing droves of chronic non-voters to the polls because at last they have a choice, not an echo—and along the way transforming the political system. Sanders can point to his large crowds and impressive, even astonishing, success at tapping into a small-donor base that exceeds, in breadth and depth, the remarkable one built in 2008 by Barack Obama. Cruz points to his extraordinarily sophisticated voter-identification operation, one that certainly seemed to do the trick in Iowa.
But is there any real evidence that there is a hidden “sleeper cell” of potential voters who are waiting for the signal to emerge and transform the electorate? No. Small-donor contributions are meaningful and a sign of underlying enthusiasm among a slice of the electorate, but they represent a tiny sliver even of that slice; Ron Paul’s success at fundraising (and his big crowds at rallies) misled many analysts into believing that he would make a strong showing in Republican primaries when he ran for president. He flopped.
Thenew Daily Show host, Trevor Noah, is smooth and charming, but he hasn’t found his edge.
It’s a psychic law of the American workplace: By the time you give your notice, you’ve already left. You’ve checked out, and for the days or weeks that remain, a kind of placeholder-you, a you-cipher, will be doing your job. It’s a law that applies equally to dog walkers, accountants, and spoof TV anchormen. Jon Stewart announced that he was quitting The Daily Show in February 2015, but he stuck around until early August, and those last months had a restless, frazzled, long-lingering feel. A smell of ashes was in the air. The host himself suddenly looked quite old: beaky, pique-y, hollow-cheeky. For 16 years he had shaken his bells, jumped and jangled in his little host’s chair, the only man on TV who could caper while sitting behind a desk. Flash back to his first episode as the Daily Show host, succeeding Craig Kilborn: January 11, 1999, Stewart with floppy, luscious black hair, twitching in a new suit (“I feel like this is my bar mitzvah … I have a rash like you wouldn’t believe.”) while he interviews Michael J. Fox.
Republicans may have a lock on Congress and the nation’s statehouses—and could well win the presidency—but the liberal era ushered in by Barack Obama is only just beginning.
Over roughly the past 18 months, the following events have transfixed the nation.
In July 2014, Eric Garner, an African American man reportedly selling loose cigarettes illegally, was choked to death by a New York City policeman.
That August, a white police officer, Darren Wilson, shot and killed an African American teenager, Michael Brown, in Ferguson, Missouri. For close to two weeks, protesters battled police clad in military gear. Missouri’s governor said the city looked like a war zone.
In December, an African American man with a criminal record avenged Garner’s and Brown’s deaths by murdering two New York City police officers. At the officers’ funerals, hundreds of police turned their backs on New York’s liberal mayor, Bill de Blasio.
Rand Paul, once viewed as the frontrunner, is leaving the Republican race after never gaining much momentum. So is Rick Santorum.
The story of Rand Paul’s presidential campaign, which he’s suspending today, is one of unfulfilled expectations.
Paul, a first-term senator from Kentucky, entered the race with high hopes. In January 2014, my colleague Peter Beinart deemed him the Republican frontrunner. A few months later, in October, Time named him “the most interesting man in politics.” But voters never seemed to agree, and he limped into Iowa trailing in the polls, and he ended up tallying less than 5 percent there—better than Jeb Bush, but still not a figure that set him up to compete down the road.
It’s understandable why Paul’s presidential prospects once seemed so bright. The nation was in the midst of what appeared to be a “libertarian moment.” Liberals and conservatives alike were joined in their backlash against an overweening security state, revealed by Edward Snowden. Newfound skepticism about the police fit in, too, and Paul was talking about the GOP’s dire need to reach out to minorities like no other candidate. The Tea Party, which had helped him upset an establishment candidate in the Kentucky Senate primary, was still a major force. His 13-hour filibuster of CIA Director John Brennan’s nomination won widespread acclaim. While rivals like Ted Cruz and Marco Rubio either alienated colleagues or flailed, Paul was consolidating the support—unexpectedly—of Mitch McConnell, the powerful Senate majority leader and fellow Kentuckian. Paul was also expected to bring in the organizational energy and know-how that his father, former Representative Ron Paul, had built over many years.
The justices will take on a complicated set of cases related to the birth-control mandate in the Affordable Care Act.
On Friday, the Supreme Court decided to tackle the case of the Little Sisters of the Poor, a group of nuns who believe, along with some priests, a Roman Catholic Archdiocese, and several universities, that the government is compelling them to violate their beliefs. Their claim: The so-called birth-control mandate of the Affordable Care Act places a burden on their religious exercise, even with an accommodation from the government.
The first thing to know about these cases is that they are incredibly complicated. The Court granted cert in seven different cases related to this topic, which means they’ve agreed to hear the questions in those seven cases. All of them have come through different circuit courts in the past months, where they’ve mostly lost. But, these cases are a big deal: They are the latest in a long series of challenges to this portion of the law, the most notable of which was last summer’s Hobby Lobby case, which involved for-profit employers.
If passion is a job requirement, says the writer Miya Tokumitsu, employees have little room to complain about mistreatment at work.
It’s been said in many places and by many luminaries: Do what you love.
But what does this phrase actually mean?
Miya Tokumitsu, a contributing editor at Jacobin magazine and author of the new book Do What You Love And Other Lies About Success and Happiness, criticizes the pervasiveness of this idea in American work culture. She argues that “doing what you love” has been co-opted by corporate interests, giving employers more power to exploit their workers.
I recently spoke with Tokumitsu about work myths and why we should pay attention to them. The following transcript of our conversation has been edited for clarity.
Bourree Lam: Your book started as an essay, “In the Name of Love,” (which was later republished by Slate) that really touched a nerve with people. What were you talking about in that essay and why are people so drawn to it?
The Florida senator’s fiery rhetoric is an acknowledgement that today’s GOP is Donald Trump’s party.
On Monday in New Hampshire, Marco Rubio virtually accused President Obama of treason. “It’s now abundantly clear,” the Florida senator declared, that “Barack Obama has deliberately weakened America.” The president, Rubio continued, wants to “humble” the United States because he believes “our power has done more harm than good.” Essentially, Obama hates America and is working to bring it down.
Why is Rubio accusing Obama of purposely sabotaging America’s well-being? It probably has less to do with Rubio’s analysis of international politics than with his analysis of Republican primary politics. Basically, he’s been Trumped.
Obama entered the White House believing that America was overstretched. He believed George W. Bush’s decisions to invade Iraq and Afghanistan, in wars paid for on the national credit card, had hollowed the American military, distracted the country from challenges at home, cost trillions, and damaged America’s reputation overseas. So, like Dwight Eisenhower during Korea and Richard Nixon during the waning years of Vietnam, Obama sought to end costly land wars and bring America’s international commitments into better alignment with its resources.
The championship game descends on a city failing to deal with questions of affordability and inclusion.
SAN FRANCISCO—The protest kicked off just a few feet from Super Bowl City, the commercial playground behind security fences on the Embarcadero, where football fans were milling about drinking beer, noshing on $18 bacon cheeseburgers, and lining up for a ride on a zip line down Market Street.
The protesters held up big green camping tents painted with slogans such as “End the Class War” and “Stop Stealing Our Homes,” and chanted phrases blaming San Francisco Mayor Ed Lee for a whole range of problems, including the catchy “Hey Hey, Mayor Lee, No Penalty for Poverty.” They blocked the sidewalk, battling with tourists, joggers, and city workers, some of whom were trying to wheel their bikes through the crowd to get to the ferries that would take them home.
