Facebook and mobile phones

Will Home work?

Apr 4th 2013, 23:24 by M.G | SAN FRANCISCO



A DAY after the mobile phone celebrated its 40th birthday, Facebook has produced something that it hopes will make certain of the devices even more useful. On April 4th the giant social network unveiled Home, new software that is designed to give it more prominence on mobile phones powered by Android, an operating system developed by Google.

This matters because more and more folk are now accessing social networks from mobile devices rather than from desktop computers and because mobile advertising revenues are growing fast, albeit from a low base. Without a robust mobile presence, Facebook could see some of its users siphoned off by rivals born in the mobile era. And it could miss out on a potentially massive source of new revenue.

There had been speculation that Facebook was working on a phone of its own, or at least on a mobile operating system to rival Android or Apple’s iOS. But dabbling in hardware at this stage of its development would be a huge risk for Facebook and developing a rival operating system would risk alienating Apple and Google, whose mobile platforms have helped power its advertising growth. EMarketer, a research firm, reckons Facebook is on track to win 11% of the $13.6 billion likely to be spent around the world on mobile ads this year.

     The ability of a helicopter to hover and land almost anywhere makes it an enormously useful machine. But helicopters have their limitations, particularly when it comes to flying fast. In a recent series of test flights, a new type of chopper has begun smashing speed records.

     The x2 is an experimental helicopter being developed by Sikorsky, an American company, which hopes it will be zipping along at more than 460kph. The company, however, is interested in more than just breaking speed records. It plans to use the technology developed for the x2 in commercial helicopters.

     Sikorsky reckons that future helicopters built using the x2 technology would be extremely versatile machines. They would dash to and from a medical emergency a lot faster. They would also be very agile in flight, which would increase their capabilities in combat.

Lawsuits claim Knoedler made huge profits on fakes

For more than a dozen years the Upper East Side gallery Knoedler & Company was “substantially dependent” on profits it made from selling a mysterious collection of artwork that is at the center of a federal forgery investigation, former clients of this former gallery have charged in court papers. The analysis is based on financial records turned over as part of a lawsuit against the gallery filed by Domenico and Eleanore De Sole, who in 2004 paid $8.3 million for a painting attributed to Mark Rothko that they now say is a worthless fake. The Rothko is one of approximately 40 works that Knoedler, which closed last year, obtained from Glafira Rosales, a littleknown dealer whose collection of works attributed to Modernist masters has no documented provenance and is the subject of an F.B.I. investigation. Between 1996 and 2008, the suit asserts, Knoedler earned approximately $60 million from works that Ms. Rosales provided on consignment or sold outright to the gallery and cleared $40 million in profits. In one year, 2002, for example, the complaint says the gallery’s entire profit — $5.6 million — was derived from the sale of Ms. Rosales’s works. “Knoedler’s viability as a business was substantially — and, in some years, almost entirely — dependent on sales from the Rosales Collection,” the De Soles claimed last month in an amended version of the suit they filed this year. While the forgery allegations are well known and have been the subject of three federal lawsuits against Knoedler, the recent filings expand the known number of Rosales artworks that were handled by the gallery, which was in business for 165 years, and assert that they played a pivotal role in the gallery’s success. After the F.B.I. issued subpoenas to the gallery in the fall of 2009, Michael Hammer, Knoedler’s owner, halted the sale of any Rosales works. Knoedler ended up losing money that year and in 2010, the court papers say. http://www.nytimes.com/2012/10/22/arts/design/knoe...

Model copes with chaos to deliver relief Computer program helps responders transport supplies in tough conditions
By Rachel Ehrenberg Science News, Web edition: Monday, February 21st, 2011
WASHINGTON — Getting blood or other perishable supplies to an area that’s been struck by an earthquake or hurricane isn’t as simple as asking what brown can do for you. But a new model quickly determines the best routes and means for delivering humanitarian aid, even in situations where bridges are out or airport tarmacs are clogged with planes.
The research, presented February 18 at the annual meeting of the American Association for the Advancement of Science, could help get supplies to areas which have experienced natural disasters or help prepare for efficient distribution of vaccines when the flu hits.
Efficient supply chains have long been a goal of manufacturers, but transport in fragile networks — where supply, demand and delivery routes may be in extremely rapid flux — requires a different approach, said Anna Nagurney of the University of Massachusetts Amherst, who presented the new work. Rather than considering the shortest path from one place to another to maximize profit, her system aims for the cleanest path at minimum cost, while capturing factors such as the perishability of the product and the uncertainty of supply routes. ‘You don’t know where demand is, so it’s tricky,’ said Nagurney. ‘It’s a multicriteria decision-making problem.’
By calculating the total cost associated with each link in a network, accounting for congestion and incorporating penalties for time and products that are lost, the computer model calculates the best supply chain in situations where standard routes may be disrupted.
‘Mathematical tools are essential to develop formal means to predict, and to respond to, such critical perturbations,’ said Iain Couzin of Princeton University, who uses similar computational tools to study collective animal behavior. ‘This is particularly important where response must be rapid and effective, such as during disaster scenarios … or during epidemics or breaches of national security.
’ The work can be applied to immediate, pressing situations, such as getting blood, food or medication to a disaster site, or to longer-term problems such as determining the best locations for manufacturing flu vaccines. . Retrieved April 7th, 2011.
