Samsung SGH-i337 hits FCC with AT&T LTE bands, fits the GS 4 profile

Samsung SGHi337 hits FCC with AT&T LTE bands, fits the GS 4 profile

We have to be skeptical when new devices arrive at the FCC without photos or a blinking sign that says "I Am AT&T's Samsung Galaxy S 4." But even doubters can connect the dots in this case and declare that a certain Samsung SGH-i337 that the FCC just waved through is likely that very model. Why? First off, it's carrying a certain LTE band 17 used exclusively by AT&T in the US. Secondly, the dimensions line up perfectly with what we recently got our hands on at Samsung's recent Galaxy S 4 phone-a-palooza. Finally, we already saw a device packing the same model number on UAProf, a normally reliable source that revealed a 1,080 x 1920 screen and "ARM11" Exynos processor. Since it's unlikely the carrier has another unannounced 1080p model coming from Samsung, those coveting an AT&T GS 4 can probably start warming up their wallets.

Minister Mbalula must help SA swimmers get to - Newsroom - DA

Winston Rabotapi, Shadow Minister of Sport and Recreation
1 April 2013

The DA calls on Minister of Sport and Recreation, Fikile Mbalula, to assist South Africa?s swimmers competing in the 2013 FINA World Championships. This follows revelations that the swimmers will have to pay for themselves due to a lack of funds at Swimming SA.

Expecting swimmers to pay their own way undermines the growth and development of sport and the performance of our elite athletes. Our sports men and women need to focus on winning medals for their country, not on fundraising.

There is something wrong when the Department of Sport and Recreation spends millions on non-core activities, but does not do enough to assist our athletes when they compete at the highest level.

Not so long ago, in 2011, the Department of Sport and Recreation spent more than 60% of the National Lottery Board?s contribution on a lavish R46 million sports awards ceremony. And the Department has point-blank refused to reveal how much it cost to send a delegation of government officials to the Olympics last year. Our sport stars are a source of national pride. The Department must get its priorities right and help find funding for South African swimmers so that they can compete in Barcelona.

Research could improve heat dissipation in 3-D systems

Apr. 2, 2013 ? Researchers from the Georgia Institute of Technology have won a Defense Advanced Research Projects Agency (DARPA) contract to develop three-dimensional chip cooling technology able to handle heat loads as much as ten times greater than systems commonly used today.

In addition to higher overall chip heat dissipation demands, the new approach will also have to handle on-chip hot spots that dissipate considerably more power per unit area than the remainder of the device. Such cooling demands may be needed for future generations of high-performance integrated circuits embedded in a wide range of military equipment.

"There is really no good way to address this heat dissipation need with existing technology, and the problem is getting worse because computing power is increasing and the capabilities being put on chips are expanding," said Yogendra Joshi, a professor in Georgia Tech's Woodruff School of Mechanical Engineering and the project's principal investigator. "There is a real need for developing schemes that can address high power on the whole chip coupled with very high power dissipation areas that are only a few millimeters square."

DARPA's Microsystems Technology Office, which provided the three-year $2.9 million contract, is seeking techniques to dissipate heat of as much as one kilowatt per square centimeter in the overall integrated circuit, and five kilowatts per square centimeter on smaller areas. The research is part of DARPA's Intrachip/Interchip Enhanced Cooling (ICECool) program.

"The approaches that we are talking about are relatively high-risk," said Joshi, who specializes in electronic cooling from the chip-level on up to full-sized data centers. "They have not been tried before, so there are real questions of reliability -- whether they can hold up under repeated cycles of being powered up and powered down."

In addition to Joshi, the research team includes:

  • Muhannad Bakir, an associate professor in the Georgia Tech School of Electrical and Computer Engineering, who specializes in three-dimensional interconnected systems;
  • Andrei Fedorov, a professor in the Georgia Tech School of Mechanical Engineering, who specializes in understanding and utilizing unique physical properties at the nanoscale, and
  • Suresh Sitaraman, also a professor in the Georgia Tech School of Mechanical Engineering, who specializes in evaluating electronic device reliability through innovative characterization techniques and physics-based modeling.

While applications for the high-powered chips aren't specified, their installation in systems intended for field use will add to the level of challenge.

"For speed and performance issues, this computing power may be embedded where it is needed in the field," Joshi said. "The challenges of cooling these high performance integrated circuits will be even more challenging because they will operate in environments that may be adverse compared to an office or computer room situation."

Among the significant challenges ahead are:

  • Implementing non-uniform cooling using liquid evaporation in three dimensional integrated circuits. The program calls for two dies to be cooled together, but the approaches developed for that could be used in multiple stacked dies. Being able to cool smaller areas with higher heat dissipation needs will provide an additional challenge.
  • Meeting reliability standards while ensuring that the coolant and vaporization within tiny microfluidic passages does not induce liquid dry-out, passage cracking, fluid leakage or undesirable electronic performance.
  • Fabricating micron-scale cooling structures smaller than the thickness of a hair in the integrated circuit stack and understanding the flow and heat transfer physics taking place at that scale.

"It is well known that cooling constraints play a critical role in designing electronic systems," said Bakir. "Often a favorable electronic system configuration may not be realizable due to lack of adequate cooling. The novel microscale thermal technologies that will result from this project will address the most demanding thermal needs of future heterogeneous 3-D nanoelectronic systems and will enable new levels of performance and energy efficiency."

Beyond the technology challenges, the researchers will also need to develop a detailed and fundamental understanding of how liquids boil at the micron size scale.

"The physics of how liquids boil has been well studied for large systems such as power plant boilers," Joshi noted. "What we are talking about here is boiling that will take place in passages that are produced by microfabrication techniques that may be only 50 micrometers by 50 micrometers. The physics of what will be going on there is very different than what happens at the large scale, and how these liquids boil in the passages of interest will result in new scientific insights."

Selecting an appropriate coolant able to provide the necessary phase change performance -- while not damaging the silicon chips -- will be part of the project. In an earlier research program supported by the Office of Naval Research, Georgia Tech developed new coolant candidates that will be considered along with traditional dielectric fluids.

The research will be done in collaboration with industry partner Rockwell-Collins, a major manufacturer of electronic systems for the military. That collaboration will help ensure that solutions developed will be compatible with defense system requirements.

"The challenges for material characterization and physics-based modeling are to consider the larger features of the electronic system without overlooking the micrometer and sub-micrometer scale features that are the main locations for fracture and failure," said Sitaraman. "Mechanical characterization and physics-based modeling will be important to understanding the reliability of microelectronic systems operating with fluid passages."

Beyond meeting the project requirements, the research will produce technology advances that should be broadly useful for future microsystems.

"The technologies we have proposed aim to explore uncharted territory in multiple science and technology domains to bring about an order-of-magnitude improvement in the current state-of-the-art," said Fedorov. "The project represents a significant challenge on the most fundamental level of materials and fluid behavior down to the sub-micron scale. We're confident that this project will produce some really new technologies to address the needs of future 3-D microsystems."

3 killed in 75-vehicle pileup at Virginia-NC line

GALAX, Va. (AP) ? About 75 vehicles crashed Sunday along a mountainous, foggy stretch of interstate near the Virginia-North Carolina border, killing three people and injuring more than 20 others, police said.

Traffic backed up for about 8 miles in the southbound lanes of I-77 in southwest Virginia. Authorities closed the northbound lanes so fire trucks, ambulances and police could get to the wreck.

A series of crashes began around 1:15 p.m. Sunday in the area of Fancy Gap Mountain. There was heavy fog at the time and photos of the scene after the accident showed poor visibility.

"This mountain is notorious for fog banks. They have advance signs warning people. But the problem is, people are seeing well and suddenly they're in a fog bank," said Glen Sage of the American Red Cross office in Galax.

The Red Cross was setting up a shelter at a Veterans of Foreign Wars post for people stranded by the pileup.

Several vehicles caught fire in the wreck, but the blaze was put out, Virginia State Police spokeswoman Corinne Geller said.

About 10 people were taken to Northern Hospital of Surry County in Mount Airy, N.C., for mostly minor injuries, said Carol Porey, a supervisor there. The extent of the other injuries wasn't immediately clear.

Authorities did not know how long the interstate would be closed. Tow trucks worked to clear some of the wrecked cars and trucks.

Sage said school buses took about two dozen people to the shelter and more were expected. The site was set up to accommodate 100 people.

Relatives likely would pick up local residents brought to the shelter. People passing through might need to stay overnight, he said.

Motorists were advised to seek alternate routes.

Easter by the numbers: How many Peeps will we eat?

Easter Sunday will cost $145.13 per person this year, and the marshmallow Peeps made per year could circle the earth twice. Easter by the numbers:?

With no disrespect meant whatsoever, Easter makes for some heavy cognitive dissonance. One the one hand, millions of Christians worldwide will mark the death and resurrection of Jesus. And on the other, you've got chocolate bunnies and jelly beans galore.

And as with any other occasion on our calendars, Easter marks yet another holiday made for spending, and consuming copious quantities of chocolate. This year, the National Retail Federation estimates that the average celebrant will spend approximately $145.13 on candy, decor, apparel, and food. And after conducting our own Easter egg hunt for stats, we've got other numbers on tap regarding this Spring holiday.

So whether you're hiding eggs in the backyard or planning a big family brunch, here's the rundown on stats, spending, and trivia surrounding this holiday that dates back to the 4th century. Read on, and fist bump that hippity-hoppity Easter Bunny as he's passing by.

Easter Garb: $25.91 Per Person

The NRF tells us that much of this spending will be done on behalf of the kiddos, in the form of bright new outfits. And as the song "Easter Parade" hints, you can bet that some ladies will spend money on a new Easter bonnet, with all the frills upon it. But hey, guys get into the act, too. There are quite a few pictures on Jezebel from the 2011 Easter Parade in NYC, and we saw all manner of headgear from psuedo-flower pot puppy caps to frosting-pink TV-shaped boxes adorned with none other than rabbit ears.

Sweet Tooth Spending: $20.66 Per Person

Americans love their candy holidays: Halloween, Valentine's Day, Christmas, and 80% Cacao Chocolate Day (which is every day for this writer). While Valentine's tends to be a time for truffles and gift-box candy, it's jelly beans and chocolate bunnies that reign supreme come Easter Time. But as you might expect, there's some debate about the best way to consume a chocolate bunny. The folks at Statistic Brain, citing figures from the National Confectioner's Association, tell us that 3 in 4 Americans (76%) think choco-rabbits should be eaten ears first. And when you think about it, biting just about anywhere else constitutes cruelty to candy animals.

Peeps Made Per Day: 4.2 Million

If Christmas has the inedible, incredible fruitcake, then Easter has the Peep, a bizarre bit of culinary mystery food that seems both cool and, yes, cruel to eat. (These are baby chicks, people!) The factory that makes Peeps is cranking out enough of these sugar birdies in a year to circle the Earth twice, according to Business News Daily. By the way, it took 27 hours to create one Peeps marshmallow chick in 1953. Today, thanks to advances in technology, it takes six minutes. Also back in 1953, it took about 45 seconds to eat a Peep. Today, thanks to advances in the American appetite for strange junk food, it takes about six seconds.

Easter Jelly Beans Confectioned: 16 Billion

This one also comes to us from Statistic Brain, and it's a daunting, daunting number. We don't know how America's confectioners keep count. But here's how it breaks down: This are 2.3 jelly beans for every man, woman, and child on Planet Earth. Who knew a little orb of candy-coated sugar could prove such an Easter enticement? Variety-wise, the folks at Jelly Belly make their beans in 50 different flavors, including Cream Soda, Tangerine, Green Apple, and Root Beer. As for myself, I'm growing more worried each year that Jelly Belly will come out with a Christmas Fruitcake jelly bean, one that has the same chewing-on-a-tire consistency as the real thing.

An Easter Brunch for the Family: $45.26

Enough with junk food! The NRF estimates that spending on items for an Easter meal will cost about $45 range. What's fascinating is how much Easter grub varies from culture to culture, family to family. In my Italian-American family, Easter meant lasagna, chicken cutlets, meatballs, and little nougat candies called "torrone," which is Italian for "tower." (Here is a great recipe from Martha Stewart.) In a Polish household, the favorites include kielbasa, ham, and babka (a slightly sweet yeast bread). Among Mexican families, you might find fried plantains, nodal (a flat-leafed cactus), or shrimp covered with a traditional sauce called pippin, made with spices and pumpkin seeds. Yum!

Oldest Official Easter Parade: 137 Years Old

It's said that Irving Berlin took a really long time to write "Easter Parade" ? about 15 years, on and off ? and by the time the song became a hit in the 1930s, the parade tradition in the U.S. was already decades old. The first official parade dates to 1876, the year officials in Atlantic City, N.J. kicked off their promenade, hoping to draw crowds from Philadelphia's Centennial Exposition. But truth be told, the tradition was taken from New York City, which had its own Easter parades going (sort of) years before. New York City's Easter parades actually began by accident, in the mid-1800s, when well-heeled church patrons leaving services would stroll along 5th Avenue in their finery. Atlantic City's parade on the Boardwalk this year hardly seems a big deal; sadly, there's barely any mention of it anywhere online. But given all the city suffered in 2012, it seems as good a time as any to attend and wish the city a comeback season.

Oldest Wrapped Chocolate Easter Egg: 56 Years Old

Yup, that's right. While there's no way of counting how many Easter eggs will be dyed in how many nations, there's one egg that simply refuses to die: the one Judith Bowen, a 73-year-old from Wootton, Beds, England bought at age 17 for her mother. The full story recently appeared in the New York Daily News, and talks about how Bowen found the still-unopened, gold-wrapping covered egg at her mother's home after she had passed away in 2006. We're betting the shelf life of this egg has long since expired, too.

And so as Easter arrives, it's a good time for both reflection and celebration. No matter how you celebrate the holiday (and even if you don't), we can all look forward to it as a milestone for the beginning of spring. It's been too cold for too long in many parts of the U.S., yet no matter what the thermometer says on Easter Sunday, here's hoping it leaves a warm feeling in your heart.
