Clash In Technology

Biggest Clash In Technology, iPhone5 And Samsung S3

Biggest Clash In Technology, iPhone5 And Samsung S3: It is very obvious that people are looking forward to get the best out of the best smartphones which are available to them. With the huge brand name of Apple it is already expected that a huge number of people are waiting for the release of the iPhone 5 but with the same time no one can ignore the awesome opening of the Samsung S2 in the market which can predict a huge sale and fan following of the Samsung S3 also. So the clash between these two rivals in inevitable.

If we make a rough comparison of these two giants they both look very competitive, although several features are still not unveiled but we can assume them through the guides and the information available on net and with the discussion of professionals. If we consider the first factor of memory it looks quite a tradition of Apple that they will stick to the persistent principal of not considering an expandable memory in their products, so iPhone 5 will have only three ranges of memory including 16GB, 32GB and 64GB, while the Samsung Galaxy S3 will be consisting of 16 and 32GB standard models with an option of expendable memory due to a card slot.

Taking the screen under consideration, it is being rumored that the screen of iPhone 5 will be more better than the retina display screen in iPhone 4 and 4S, which might also constituent of OLED screen and IGZO screen, while on the other hand Samsung Galaxy S3 screen is expected to be a super AMOLED plus screen, with 720P resolution. The information spread all over the market is that the S3 would have a large 4.5 inch screen.

Comparing the operating systems of both the giants’ contenders, iPhone 5 is most likely to be run on iOS 6, which is the Apple’s latest version of operating systems. Which also have few additional charms which includes iMaps, which is rumored that they will not depend on Google map only but tipped up with the company named C3 which will make the usage of 3D maps, another additional feature will be Siri, which is becoming more versatile by making it work in maximum countries and encoding the maximum number of languages in it, while Samsung S3 on the other hand is going to be run on Ice Cream Sandwich OS, which is more user friendly operating system unlike Android predecessors including Gingerbread and Froyo.

There are still many more features which can be compared to make the analysis but the real analysis will be made when the both products will be in the hands of the customers and they will be the one which will be making the analysis. Time is coming nearby so everyone is anxiously waiting for the launch of both iPhone 5 and Samsung Galaxy S3.

How It Works: Building a Kilometer-Long Pipe Deep Under the Sea

Ocean Thermal Energy Conversion This schematic shows how the heat exchange works in an ocean thermal energy conversion plant. The heat differential between surface water and deep water in the ocean is used to generate steam and drive a turbine. Lockheed Martin

One possibility for future energy production involves harvesting the warmth of Earth’s tropical oceans, using the natural heat differentials in the water to drive turbines. It would be relatively simple if you didn’t need a ludicrously large piece of pipe, 33 feet in diameter and stretching a kilometer beneath the water. To put that in context, that’s a New York subway tunnel wide and two and a half Empire State Buildings high.

“To produce sizable amounts of power, ocean thermal energy conversion plants have to move rivers of water,” said Laurie Meyer, chief technologist for OTEC at Lockheed Martin, which is building the pipe for a new 10-megawatt pilot plant. This structure also needs to withstand the constant rocking pressure of ocean currents, atmospheric pressures at 3,200 feet deep and the variable temperature of the water it’s designed to harvest — so building the pipe has been a challenge. Here’s how Lockheed is doing it.

The oceans are huge reservoirs of warmth, especially in the tropics, where the temperature differential between warm surface water and cool deep water can reach 40 or more degrees Fahrenheit. This differential can be harnessed to run a heat engine, using some principles from utility plants, plus some from refrigeration. Warm surface water goes into a heat exchanger, which vaporizes an ammonia solution; the resulting steam drives a turbine, and the ammonia is re-condensed using cold ocean water. The water is then pumped back into the ocean, a few degrees warmer than when it came in. But to reach the energy production scales of a traditional fossil fuel-fired power plant, 100 megawatts or more, you need a whole lot of water.

Lockheed first explored OTEC in the 1970s, and it’s resurrecting the concept now in the face of rising energy prices. A 10-MW plant is expected to be operational within a couple years. Under a U.S. Navy grant, Lockheed designed a new composite material for the pipe, and engineers have been building prototypes at the company’s plant in Sunnyvale, Calif. Full-scale OTEC pipes will be made right at the site of the power plant by extruding them right into the water.

A 3,200-foot-long, 33-foot wide pipe is not something you could build in a factory, haul out to sea and drop into the water, Meyer explained. Aside from the logistical challenges of moving it along railways or barges, it would probably be impossible to raise it to the right angle and drop it down to the proper depth. Instead, Lockheed will build it in place, using techniques the company first developed for spacecraft construction.

The manufacturing process is called vacuum-assisted resin transfer moulding, and it's the same basic process Boeing uses to build its 787 Dreamliner. VARTM typically consists of a polyester or vinyl resin reinforced by fiberglass, and Lockheed settled on a customized ratio (which they wouldn’t disclose for competitive reasons) that meets all the flexibility and stability requirements for a cold water pipe.

OTEC Size Comparison: The cold water intake pipe for an ocean thermal energy conversion plant would need to be at least 1 kilometer long — just about as tall as three Empire State Buildings.  Lockheed Martin

“We designed a system to take that process and turn it vertical, which allows us to pump out sections of the pipe,” Meyer said. To make a section, the fabric and resin poured into a mould and allowed to cure, just as concrete would. A vacuum removes any imperfections and bubbles, leaving a perfectly formed tube in place. Lockheed will do this in sections, the sizes of which are still to be determined, Meyer said.

"The longer you can make a section, the faster you can finish building the whole length of pipe, but there will be some practical limit in terms of handling the finished section," she said.

The platform where these sections will be formed have to be built to withstand winds, storms, currents and other phenomena, and Lockheed will use techniques pioneered by the offshore drilling industry, she added.

For the 10-MW plant, Lockheed is building a 4-meter diameter pipe (about 13 feet). For a full-scale, 100-MW plant, the pipes would be 10 meters, or 33 feet. The length of the pipe will be determined by the depth of the cold water — in some potential OTEC sites, chilled water may lurk around 1,000 meters deep, and in others, it may be shallower. The world has plenty of areas where OTEC could work, mostly around the equator.

By the way, the pipe will also have to be built to avoid sucking in marine life. Cold deep water is nutrient-rich, but doesn’t harbor dense populations of marine life because it’s so dark — yet many mammals, squid and other creatures of the deep might swim past the intake. The U.S. Environmental Protection Agency is working with Lockheed to determine maximum intake velocities, so animals could safely swim away rather than being sucked into the pipe.

Ultimately, OTEC plants will be useful for tropical communities — like Hawaii, the Philippines, and so on — or for Navy bases, which currently rely on imported fossil fuels. It could replace or supplement traditional power plants for large-scale, baseload electricity, according to Lockheed. But it couldn't work without gigantic pipes.

Video: Flying Thing Propels Itself By Flipping Inside Out

Inversion Flying Object Festo

Flying objects can achieve forward thrust in a few ways, but here’s a unique new one: Flipping inside out to move forward. Designed by the people who brought us the amazing robot seagull, the SmartInversion flying object can move through the air indefinitely.

The object is based on a design envisioned by inventor Paul Schatz. It’s a six-sided articulated ring of prisms that attaches to a cube, and when it’s unleashed, it can start folding into new geometric shapes. As it turns itself inside out, it moves forward. This property of kinematics is called inversion.

The object is filled with helium so it will float in the air. It’s on display this week at the Hannover Messe technology trade show in Germany, where users will be able to control it with a smartphone, as seen in the video below. New Scientist reports that it’s held together by a carbon-fiber framework, and three motors control its motion, governed by a pre-programmed onboard computer.

Designers at Festo, also known for their nature-inspired robots, are now sponsoring a competition for students to figure out some practical uses for this thing.

It looks like the folded-square paper fortune-cookie game thing I used to play with in grade school. I have no idea what it’s really called, but some of you probably know what I’m talking about. Watch it fly here.

Changing The Teeth On The World’s Largest Tunnel-Boring Machine

Drill Dentists Kevin Hand

Next year, workers will start digging a 1.7-mile tunnel underneath downtown Seattle using the world’s largest tunnel-boring machine. The 57.5-foot-diameter, $80-million drill, which is currently under construction for the State Route 99 project, has about 600 cutting tools—steel bits and spinning disks on the borer’s face that break up dirt and rock. The tools may need to be inspected as often as every 400 feet, or about 20 times over the course of construction.

The Problem: Accessing the front of a boring machine that’s already belowground is hard, particularly in deep tunnels, where the air pressure is dangerously high. Repairing cutting tools, therefore, is typically a task for workers who must spend time in hyperbaric chambers each time they visit the machine to acclimate to the pressure. (Two hundred feet belowground in an enclosed tunnel can get as high as 5 bars—the equivalent of being 165 feet deep in open water.) Crews retract the front of the machine to create a space ahead where a group of about five workers operates while wearing special helmets for breathing in those conditions. They use pneumatic wrenches and hammers to loosen the teeth, and pneumatic pulleys, hoists and chains to tug them out. After installing the new bits or disks, the team returns to the surface. Replacing a single tool could take up to four hours.

The Solution: Engineers on the Seattle project have modified the design of the drill, manufactured by Hitachi Zosen, so that workers can replace the teeth from inside the safety of the machine itself. The new borer is large enough that people can work just behind the drill face at aboveground atmospheric pressure. An automated system retracts the cutting tools into the chamber, where a crew can make repairs. The chamber is also roomy enough to accommodate hydraulic pulleys and other hydraulic machines, which are more powerful than their pneumatic counterparts. The better equipment, combined with the safety and freedom from working at sea-level pressure, could make repairs about four times as fast.

You Use Google Drive?

Will You Use Google Drive?

Google Drive Google

Google has been rumored to be working on a cloud storage service for about as long as we've known what cloud storage is, and today the company finally unveiled it: Google Drive. It has a couple of nice features that competitors like Dropbox, MobileMe, SkyDrive and all the others don't, but the main selling point seems to be the same selling point as most other new Google services: hell, you're already using Google. Why not add this? So we're curious: will you?

Primer time! If you already know what I mean when I say "it's like Dropbox, but from Google," skip this paragraph and go on to the next one. (It's like a choose your own adventure game, without adventure, and with information!) Everyone else, here's what's going on: Cloud services give you a folder on your computer into which you drag whatever you'll want to access later, whether it's documents, photos, music, videos, or anything else. That's synced automatically to your cloud drive, out in a server somewhere, and you can access or share those files from any supported device (which includes computers, tablets, and smartphones). It's great! You don't have to worry about where your stuff is anymore, because you can always get to it, and you don't need to worry about emailing attachments that are too big, because you can just share files from your cloud drive, which has a whole bunch of space.

Google Drive doesn't bring many crazy-new features to cloud storage, though there are a few new ideas. We're actually pretty excited about the search functions, which might turn out to be a major differentiating factor. There's this image recognition element, so Google Drive will look through even scanned images with text, or files like PDFs that aren't normally searchable, and index all of that as well, which is something no other service has. At the Drive demonstration, a Google rep took a picture of a typewritten paper document with a phone, then sent it to Google Drive, where it was scanned and recognized. Pretty cool stuff.

And it promises to be nicely integrated with all of the Google services you love, like Gmail and YouTube and Google Docs, and also with those other services you're aware of, like Google Plus. You can open and view, says Google, over 30 kinds of files, including Photoshop and video files, even if you don't have Photoshop or video editing software on whatever device you're accessing those files with. And you can share and comment on those files directly from Gmail and Google Plus (though it's worth mentioning that many Gmail clients support other cloud services, like the Sparrow client with Dropbox).

Google Drive is apparently available now, though I see a button that says "Your Google Drive is not ready yet" on the Drive page, for Mac, PC, and Android. iOS devices like the iPhone and iPad are soon to come--they were used at the demo, so they're probably not far off. Drive starts off with 5GB for free, though you can upgrade--$2.50 a month gets you 25GB, and pricing goes all the way up to 16 terabytes of storage. (This is basically the average price, though Microsoft's SkyDrive offers a ridiculous 100GB for free.)

So here's what we're wondering: will you guys use this? Will Dropbox users drop Dropbox (eek) and switch? Will the fact that Drive is thoroughly integrated into the Google ecosystem be enough to tempt those who were never tempted by cloud storage before?

Intel's New Ivy Bridge CPUs Will Give Your Next Laptop Legit Gaming Power

Intel Ivy Bridge Processors Intel

If you buy a cheapie laptop, you're going to get onboard graphics--historically underpowered, since they exist on the same die as the CPU, and thus historically crappy. To play serious games, or do any real video editing, you'd need to upgrade to a discrete graphics card. But that looks like a thing of the past: today, Intel unleashed its new generation of processors, which go by the name Ivy Bridge, and what had seemed like an incremental upgrade actually has a pretty interesting element: these processors have onboard graphics that basically outclass the entire market of entry-level graphics cards. That means your next computer will be able to run games you'd never be able to run now--with no necessary hardware upgrades.

PCWorld has a good overview with a whole bunch of benchmarks, if you're interested in seeing the specifics, but the basic idea is that Intel has placed a much higher focus on the onboard graphics capabilities, a focus continued from the current-gen Sandy Bridge line--so much so that they actually surpass the current crop of entry-level aftermarket graphics cards. (Otherwise these chips are focused mostly on size and power consumption rather than major new features or power.) That's due to some careful internal restructuring of the GPU, according to PCWorld:

Intel has made enhancements to the GPU engine to improve efficiency, but other factors help to mitigate the clock-rate differential, too. First, the new HD 4000 GPU contains 16 execution units, versus the 12 built into Sandy Bridge. Second, Ivy Bridge supports DDR3-1600 memory, as opposed to the Sandy Bridge memory controller, which officially supports only DDR3-1333. Ivy Bridge gains 25 percent more parallel compute power and higher potential throughput due to the added memory bandwidth.

What we like here is that beyond all the wonkiness, the new chips have some big, obvious improvements for users. There are two levels of GPU, the HD 2500 and HD 4000. The latter will allow gamers to play graphics-intensive games like the new Metro 2033 and Just Cause 2 at playable framerates--definitely something that wasn't possible before with onboard graphics. Both the 2500 and 4000 support DirectX 11 and three independent displays, too. And these chips will be everywhere: Mac, Windows, laptops, desktops, big power hogs, svelte ultrabooks. Everywhere. Which is great! And it also probably means you should hold off for a month or two if you're shopping for a new computer.

Today in Mind Reading: Brain Scans Can Predict If You're About to Make a Math Mistake

Today in Mind Reading: Brain Scans Can Predict If You're About to Make a Math Mistake

Solving the Math Silenceofnight via Flickr

Along with predicting our future behaviors, brain scans can guess when we’re about to make a cognitive error, mis-processing a math problem because we’re thinking too hard. Like a dashboard widget watching your computer’s RAM, brain wave patterns can be used to detect when the brain is approaching its limits of processing power, according to new research.

Federico Cirett at the University of Arizona was studying learning differences among non-native English speakers versus fluent English speakers, and noticed the non-fluent people had more difficulty answering various types of questions. He attached an EEG to volunteers’ heads to monitor their brain activity as they solved math problems on the SAT exam, and tried to figure out why they were distracted.

The measurements were correlated with questions about how engaged the students were, their perceived levels of difficulty, and their feelings of frustration, according to the U of A, where Cirett is completing a Ph.D. The subjects were all university students, according to a university news release.

An EEG monitors waves of activity in the brain, and Cirett wrote an algorithm that classifies different types of waves. He examined the students’ responses about frustration levels, and came up with a system that can predict how well they’ll do on a given problem. Ultimately, within about 20 seconds of starting a problem, Cirett could deduce via students’ brain activity whether or not they would get it right, he says. The system works with 80 percent accuracy, much better than chance.

Surely everyone knows how it feels when your brain is overworked — that sense of fuzziness, distraction and slowness that can be the hallmark of an extremely busy Monday. So it makes sense that brain scans could pick up this feeling, noting when your brain is about to be overloaded.

Cirett and his collaborators wrote a paper about their work and will present it at a User Modeling, Adaptation and Personalization conference in Montreal in July.

Heart-Healthy Cookout Ideas

Heart-Healthy Cookout Ideas

Warmer weather may mean it’s time to break out the grill, here are some tips and ideas for a healthier grilling cookout:

• Go Fish! Fish, especially oily fish like tuna and salmon have great nutritional benefits including omega-3 fatty acids. Rub a fillet with lemon juice and parsley or rosemary for enhanced flavor.
• Make a better burger: if you’re grilling burgers, be sure to buy lean or extra lean beef, drain off the excess fat after cooking and avoid making huge patties – remember that a serving of meat is about the size of a deck of cards (3 oz). Add finely chopped green pepper to your beef to get in some veggies.
• Baked fries: Slice white or sweet potatoes into sticks, lightly spray with olive oil cooking spray, pepper and paprika and bake on a cookie sheet for 40 minutes at 375 degrees.
• Veggie kabobs: load up skewers with mushrooms, peppers, cherry tomatoes, zucchini, yellow squash or other veggies. Spray lightly with olive oil cooking spray and grill until slightly blackened.
• Try grilled corn on the cob: leave the husks on, and grill for about 30 minutes over medium flame, rotating occasionally. Remove from grill, let cool for about 5 minutes, remove husks and enjoy!
