Basic Components of Sonobuoy

The sonobuoy is gadget that accumulates and transmits data from the world’s seas. It is an innovation that dates to the principal world war, when it was created by the military to track the exercises of passing vessels. Today, an extensive variety of enterprises use the data assembling and transmitting abilities of the gadget, from military gatherings, to oil and gas investigation, to logical gatherings. They are utilized to screen various sorts of sea exercises. Movement propensities for marine life, fluctuating sea temperatures, evolving streams, transport action, and sea landscape are just a couple of the numerous things that a sonobuoy can be utilized to screen or track.

1. Floatation gadget

Every one of them have some type of buoyancy gadget. This permits a man to send it adrift, where it can drift for a timeframe and record and transmit information and not have it sink to the base of the sea. The highest point of it buoys and the base is submersed, so it can assemble data. Much of the time, alternate segments are associated by links that buoy openly. While the thought is straightforward, a bit of

Get Advantages of Electronic Recycling

On the planet today there are such a large number of gadgets, for example, computers, TVs, mobile phones, tablets that when they are no longer useable something must be finished with them. Consistently there is roughly forty-nine million metric huge amounts of electronic waste created worldwide as indicated by the United Nations Environmental Program. Of these forty-nine million metric tons, roughly three million of that electronic waste is delivered in the United States alone. At the point when a man or business picks to utilize electronic reusing they are empowering these gadgets to be reused and are changing waste material into new items. There are many advantages in electronic reusing.

There will be a cleaner domain. Most electronic waste is being dumped or sent to landfills, which are getting to be distinctly scarcer. Doing this involves a ton of space and spreads hurtful poisons by corrupting the ground water. This makes an unsafe circumstance for people, creatures, and vegetation. When you reuse your hardware, it spares space in your landfills and counteracts different territories of the land from getting to be dumping grounds. Reusing will likewise keep the poisons from

Fujitsu Liquid Immersion Not All Hot Air When It Comes to Cooling Data Centers

Given the prodigious heat generated by the trillions of transistors switching on and off 24 hours a day in data centers, air conditioning has become a major operating expense. Consequently, engineers have come up with several imaginative ways to ameliorate such costs, which can amount to a third or more of data center operations.

One favored method is to set up hot and cold aisles of moving air through a center to achieve maximum cooling efficiency. Meanwhile, Facebook has chosen to set up a data center in Lulea, northern Sweden on the fringe of the Arctic Circle to take advantage of the natural cold conditions there; and Microsoft engineers have seriously proposed putting server farms under water.

Fujitsu, on the other hand, is preparing to launch a less exotic solution: a liquid immersion cooling system it says will usher in a “next generation of ultra-dense data centers.”

Though not the first company to come up with the idea, the Japanese computer giant says it’s used its long experience in the field to come up with a design that accommodates both easy maintenance and standard servers. Maintenance is as straightforward to perform as on air-cooled systems, for it does not require

Google Plans to Demonstrate the Supremacy of Quantum Computing

Quantum computers have long held the promise of performing certain calculations that are impossible—or at least, entirely impractical—for even the most powerful conventional computers to perform. Now, researchers at a Google laboratory in Goleta, Calif., may finally be on the cusp of proving it, using the same kinds of quantum bits, or qubits, that one day could make up large-scale quantum machines.

By the end of this year, the team aims to increase the number of superconducting qubits it builds on integrated circuits to create a 7-by-7 array. With this quantum IC, the Google researchers aim to perform operations at the edge of what’s possible with even the best supercomputers, and so demonstrate “quantum supremacy.”

“We’ve been talking about, for many years now, how a quantum processor could be powerful because of the way that quantum mechanics works, but we want to specifically demonstrate it,” says team member John Martinis, a professor at the University of California, Santa Barbara, who joined Google in 2014.

A system size of 49 superconducting qubits is still far away from what physicists think will be needed to perform the sorts of computations that have long motivated quantum computing research. One of those

Brain Computers: Bad in Math, Good in Others

Painful exercises in basic arithmetic are a vivid part of our elementary school memories. A multiplication like 3,752 × 6,901 carried out with just pencil and paper for assistance may well take up to a minute. Of course, today, with a cellphone always at hand, we can quickly check that the result of our little exercise is 25,892,552. Indeed, the processors in modern cellphones can together carry out more than 100 billion such operations per second. What’s more, the chips consume just a few watts of power, making them vastly more efficient than our slow brains, which consume about 20 watts and need significantly more time to achieve the same result.

Of course, the brain didn’t evolve to perform arithmetic. So it does that rather badly. But it excels at processing a continuous stream of information from our surroundings. And it acts on that information—sometimes far more rapidly than we’re aware of. No matter how much energy a conventional computer consumes, it will struggle with feats the brain finds easy, such as understanding language and running up a flight of stairs.

If we could create machines with the computational capabilities and energy efficiency of the brain, it would be a

The Benefits of Building an Artificial Brain

In the mid-1940s, a few brilliant people drew up the basic blueprints of the computer age. They conceived a general-purpose machine based on a processing unit made up of specialized subunits and registers, which operated on stored instructions and data. Later inventions—transistors, integrated circuits, solid-state memory—would supercharge this concept into the greatest tool ever created by humankind.

So here we are, with machines that can churn through tens of quadrillions of operations per second. We have voice-recognition-enabled assistants in our phones and homes. Computers routinely thrash us in our ancient games. And yet we still don’t have what we want: machines that can communicate easily with us, understand and anticipate our needs deeply and unerringly, and reliably navigate our world.

Now, as Moore’s Law seems to be starting some sort of long goodbye, a couple of themes are dominating discussions of computing’s future. One centers on quantum computers and stupendous feats of decryption, genome analysis, and drug development. The other, more interesting vision is of machines that have something like human cognition. They will be our intellectual partners in solving some of the great medical, technical, and scientific problems confronting humanity. And their thinking may share some of the fantastic and maddening beauty, unpredictability,

We Could Build an Artificial Brain Right Now

Brain-inspired computing is having a moment. Artificial neural network algorithms like deep learning, which are very loosely based on the way the human brain operates, now allow digital computers to perform such extraordinary feats as translating language, hunting for subtle patterns in huge amounts of data, and beating the best human players at Go.

But even as engineers continue to push this mighty computing strategy, the energy efficiency of digital computing is fast approaching its limits. Our data centers and supercomputers already draw megawatts—some 2 percent of the electricity consumed in the United States goes to data centers alone. The human brain, by contrast, runs quite well on about 20 watts, which represents the power produced by just a fraction of the food a person eats each day. If we want to keep improving computing, we will need our computers to become more like our brains.

Hence the recent focus on neuromorphic technology, which promises to move computing beyond simple neural networks and toward circuits that operate more like the brain’s neurons and synapses do. The development of such physical brainlike circuitry is actually pretty far along. Work at my lab and others around the world over the

Opinion: Raspberry Pi Merger With CoderDojo Not All

This past Friday, the Raspberry Pi Foundation and the CoderDojo Foundationbecame one. The Raspberry Pi Foundation described it as “a merger that will give many more young people all over the world new opportunities to learn how to be creative with technology.” Maybe. Or maybe not. Before I describe why I’m a bit skeptical, let me first take a moment to explain more about what these two entities are.

The Raspberry Pi Foundation is a charitable organization created in the U.K. in 2009. Its one-liner mission statement says it works to “put the power of digital making into the hands of people all over the world.” In addition to designing and manufacturing an amazingly popular line of inexpensive single-board computers—the Raspberry Pi—the Foundation has also worked very hard at providing educational resources.

The CoderDojo Foundation is an outgrowth of a volunteer-led, community-based programming club established in Cork, Ireland in 2011. That model was later cloned in many other places and can now be found in 63 countries, where local coding clubs operate under the CoderDojo banner.

So both organizations clearly share a keen interest in having young people learn about computers and coding. Indeed, the Raspberry Pi Foundation had earlier

In the Future, Machines Will Borrow Our Brain’s Best Tricks

Steve sits up and takes in the crisp new daylight pouring through the bedroom window. He looks down at his companion, still pretending to sleep. “Okay, Kiri, I’m up.”

She stirs out of bed and begins dressing. “You received 164 messages overnight. I answered all but one.”

In the bathroom, Steve stares at his disheveled self. “Fine, give it to me.”

“Your mother wants to know why you won’t get a real girlfriend.”

He bursts out laughing. “Anything else?”

“Your cholesterol is creeping up again. And there have been 15,712 attempts to hack my mind in the last hour.”

“Good grief! Can you identify the source?”

“It’s distributed. Mostly inducements to purchase a new RF oven. I’m shifting ciphers and restricting network traffic.”

“Okay. Let me know if you start hearing voices.” Steve pauses. “Any good deals?”

“One with remote control is in our price range. It has mostly good reviews.”

“You can buy it.”

Kiri smiles. “I’ll stay in bed and cook dinner with a thought.”

Steve goes to the car and takes his seat.

U.S. Slips in New Top500 Supercomputer Ranking

In June, we can look forward to two things: the Belmont Stakes and the first of the twice-yearly TOP500 rankings of supercomputers. This month, a well-known gray and black colt named Tapwrit came in first at Belmont, and a well-known gray and black supercomputer named Sunway TaihuLight came in first on June’s TOP500 list, released today in conjunction with the opening session of the ISC High Performance conference in Frankfurt. Neither was a great surprise.

Tapwrit was the second favorite at Belmont, and Sunway TaihuLight was the clear pick for the number-one position on TOP500 list, it having enjoyed that first-place ranking since June of 2016 when it beat out another Chinese supercomputer, Tianhe-2. The TaihuLight, capable of some 93 petaflops in this year’s benchmark tests, was designed by the National Research Center of Parallel Computer Engineering & Technology (NRCPC) and is located at the National Supercomputing Center in Wuxi, China. Tianhe-2, capable of almost 34 petaflops, was developed by China’s National University of Defense Technology (NUDT), is deployed at the National Supercomputer Center in Guangzho, and still enjoys the number-two position on the list.

More of a surprise, and perhaps more of a disappointment for some, is that the highest-ranking U.S. contender, the Department

Global Race Towards Exascale Will Drive Supercomputing

For the first time in 21 years, the United States no longer claimed even the bronze medal. With this week’s release of the latest Top 500 supercomputer ranking, the top three fastest supercomputers in the world are now run by China (with both first and second place finishers) and Switzerland. And while the supercomputer horserace is spectacle enough unto itself, a new report on the supercomputer industry highlights broader trends behind both the latest and the last few years of Top500 rankings.

The report, commissioned last year by the Japanese national science agency Riken, outlines a worldwide race toward exascale computers in which the U.S. sees R&D spending and supercomputer talent pools shrink, Europe jumps into the breach with increased funding, and China pushes hard to become the new global leader, despite a still small user and industry base ready to use the world’s most powerful supercomputers.

Steve Conway, report co-author and senior vice president of research at Hyperion, says the industry trend in high-performance computing is toward laying groundwork for pervasive AI and big data applications like autonomous cars and machine learning. And unlike more specialized supercomputer applications from years past, the workloads of tomorrow’s supercomputers will likely be mainstream and even consumer-facing

Search Engines for Brain Available at Sight: The Reboot Human Brain Project

The human brain is smaller than you might expect: One of them, dripping with formaldehyde, fits in a single gloved hand of a lab supervisor here at the Jülich Research Center, in Germany.

Soon, this rubbery organ will be frozen solid, coated in glue, and then sliced into several thousand wispy slivers, each just 60 micrometers thick. A custom apparatus will scan those sections using 3D polarized light imaging (3D-PLI) to measure the spatial orientation of nerve fibers at the micrometer level. The scans will be gathered into a colorful 3D digital reconstruction depicting the direction of individual nerve fibers on larger scales—roughly 40 gigabytes of data for a single slice and up to a few petabytes for the entire brain. And this brain is just one of several to be scanned.

Neuroscientists hope that by combining and exploring data gathered with this and other new instruments they’ll be able to answer fundamental questions about the brain. The quest is one of the final frontiers—and one of the greatest challenges—in science.

Imagine being able to explore the brain the way you explore a website. You might search for the corpus callosum—the stalk that connects the brain’s two hemispheres—and then

Chip Hall of Fame: Western Digital WD1402A UART

Gordon Bell is famous for launching the PDP series of minicomputers at Digital Equipment Corp. in the 1960s. These ushered in the era of networked and interactive computing that would come to full flower with the introduction of the personal computer in the 1970s. But while minicomputers as a distinct class now belong to the history books, Bell also invented a lesser known but no less significant piece of technology that’s still in action all over the world: The universal asynchronous receiver/transmitter, or UART.

UARTs are used to let two digital devices communicate with each other by sending bits one at a time over a serial interface without bothering the device’s primary processor with the details.

Today, more sophisticated serial setups are available, such as the ubiquitous USB standard, but for a time UARTs ruled supreme as the way to, for example, connect modems to PCs. And the simple UART still has its place, not least as the communication method of last resort with a lot of modern network equipment.

The UART was invented because of Bell’s own need to connect a Teletype to a PDP-1, a task that required converting parallel signals into serial signals. He cooked

Rigetti Launches Full-Stack Quantum Computing Service and Quantum IC Fab

Much of the ongoing quantum computing battle among tech giants such as Google and IBM has focused on developing the hardware necessary to solve impossible classical computing problems. A Berkeley-based startup looks to beat those larger rivals with a one-two combo: a fab lab designed for speedy creation of better quantum circuits and a quantum computing cloud service that provides early hands-on experience with writing and testing software.

Rigetti Computing recently unveiled its Fab-1 facility, which will enable its engineers to rapidly build new generations of quantum computing hardware based on quantum bits, or qubits. The facility can spit out entirely new designs for 3D-integrated quantum circuits within about two weeks—much faster than the months usually required for academic research teams to design and build new quantum computing chips. It’s not so much a quantum computing chip factory as it is a rapid prototyping facility for experimental designs.

“We’re fairly confident it’s the only dedicated quantum computing fab in the world,” says Andrew Bestwick, director of engineering at Rigetti Computing. “By the standards of industry, it’s still quite small and the volume is low, but it’s designed for extremely high-quality manufacturing of these quantum circuits that emphasizes speed and flexibility.”

But Rigetti is not betting on faster hardware innovation alone. It

Qudits: The Real Future of Quantum Computing?

Instead of creating quantum computers based on qubits that can each adopt only two possible options, scientists have now developed a microchip that can generate “qudits” that can each assume 10 or more states, potentially opening up a new way to creating incredibly powerful quantum computers, a new study finds.

Classical computers switch transistors either on or off to symbolize data as ones and zeroes. In contrast, quantum computers use quantum bits, or qubits that, because of the bizarre nature of quantum physics, can be in a state of superposition where they simultaneously act as both 1 and 0.

The superpositions that qubits can adopt let them each help perform two calculations at once. If two qubits are quantum-mechanically linked, or entangled, they can help perform four calculations simultaneously; three qubits, eight calculations; and so on. As a result, a quantum computer with 300 qubits could perform more calculations in an instant than there are atoms in the known universe, solving certain problems much faster than classical computers. However, superpositions are extraordinarily fragile, making it difficult to work with multiple qubits.

Most attempts at building practical quantum computers rely on particles that serve as qubits. However, scientists have long known that they could in principle

An Early Door to Cyberspace: The Computer Memory Terminal

COMMUNITY MEMORY is the name we give to this experimental information service. It is an attempt to harness the power of the computer in the service of the community. We hope to do this by providing a sort of super bulletin board where people can post notices of all sorts and can find the notices posted by others rapidly.

We are Loving Grace Cybernetics, a group of Berkeley people operating out of Resource One Inc., a non-profit collective located in Project One in S.F. Resource One grew out of the San Francisco Switchboard and has managed to obtain control of a computer (XDS 940) for use in communications.

Pictured above is one of the Community Memory teletype terminals. The first was installed at Leopold’s Records, a student-run record store in Berkeley. The terminal connected by modem to a time-sharing computer in San Francisco, which hosted the electronic bulletin-board system. Users could exchange brief messages about a wide range of topics: apartment listings, music lessons, even where to find a decent bagel. Reading the bulletin board was free, but posting a listing cost a quarter, payable by the coin-op mechanism. The terminals offered many users their first interaction with a computer.

Ordinary Computer Can Access The Secret of Quantum Computing

You may not need a quantum computer of your own to securely use quantum computing in the future. For the first time, researchers have shown how even ordinary classical computer users could remotely access quantum computing resources online while keeping their quantum computations securely hidden from the quantum computer itself.

Tech giants such as Google and IBM are racing to build universal quantum computers that could someday analyze millions of possible solutions much faster than today’s most powerful classical supercomputers. Such companies have also begun offering online access to their early quantum processors as a glimpse of how anyone could tap the power of cloud-based quantum computing. Until recently, most researchers believed that there was no way for remote users to securely hide their quantum computations from prying eyes unless they too possessed quantum computers. That assumption is now being challenged by researchers in Singapore and Australia through a new paper published in the 11 July issue of the journal Physical Review X.

“Frankly, I think we are all quite surprised that this is possible,” says Joseph Fitzsimons, a theoretical physicist for the Centre for Quantum Technologies at the National University of Singapore and principal investigator on the study. “There had been a number

Human OS ComputingHardware Low Cost Play Materials

Researchers have made a low-cost smart glove that can translate the American Sign Language alphabet into text and send the messages via Bluetooth to a smartphone or computer. The glove can also be used to control a virtual hand.

While it could aid the deaf community, its developers say the smart glove could prove really valuable for virtual and augmented reality, remote surgery, and defense uses like controlling bomb-diffusing robots.

This isn’t the first gesture-tracking glove. There are companies pursuing similar devices that recognize gestures for computer control, à la the 2002 film Minority Report. Some researchers have also specifically developed gloves that convert sign language into text or audible speech.

What’s different about the new glove is its use of extremely low-cost, pliable materials, says developer Darren Lipomi, a nanoengineering professor at the University of California, San Diego. The total cost of the components in the system reported in the journal PLOS ONE cost less than US $100, Lipomi says. And unlike other gesture-recognizing gloves, which use MEMS sensors made of brittle materials, the soft stretchable materials in Lipomi’s glove should make it more robust.

The key components of the new glove are flexible strain sensors made of a rubbery polymer. Lipomi and his team make the

Complex Biological Computer Commands Living Cells

Researchers have developed a biological computer that functions inside living bacterial cells and tells them what to do, according to a report published today in Nature. Composed of ribonucleic acid, or RNA, the new “ribocomputer” can survive in the bacterium E. coli and respond to a dozen inputs, making it the most complex biological computer to date.

“We’ve developed a way to control how cells behave,” says Alexander Green, an engineer at The Biodesign Institute at Arizona State University, who developed the technology with colleagues at Harvard’s Wyss Institute for Biologically Inspired Engineering. The cells go about their normal business, replicating and sensing what’s going on in their environments, “but they’ve also got this layer of computational machinery that we’ve instructed them to synthesize,” he says.

The biological circuit works just like a digital one: It receives an input and makes a logic-based decision, using AND, OR, and NOT operations. But instead of the inputs and outputs being voltage signals, they are the presence or absence of specific chemicals or proteins.

The process begins with the design of a DNA strand that codes for all the logic the system will need. The researchers insert the
