The 20 million residents of mumbai slog through monstrous traffic jams during monsoon season. The heavy rains that last from June until August frequently choke off the flow of traffic through India's most populous city, leaving millions of Mumbaikars seething in their cars after a workday.

And meanw Problems with VHDL are considered. SpaceX has, of course, been ferrying quite a bit of stuff into space lately. They were for an initial test of gear intended for use in a globe-spanning broadband data network, called Starlink, made up of thousands of small satellites. Bitcoin soaks up most of the hype and the opprobrium heaped on cryptocurrencies, leaving its younger and smaller sibling Ethereum in the shadows.

But Ethereum is anything but small. For most of the past 50 years, the areal density of hard disks-a measure of how many bits of data that engineers can squeeze into a given area-increased by an average of nearly 40 percent each year. Lately, though, that rate has slowed to around 10 percent. Everyone who works on magnetic storage is well aware of this problem, but only in the past year or so have executives from Seagate Technology What's the most important thing for people to know about the full-body exoskeleton from Sarcos Robotics, which can turn an assembly-line worker into a superhero?

At a test track east of Gothenburg, Sweden, people are ushered into autonomous vehicles for a test drive. But there's a twist: The vehicles aren't actually autonomous-there's a hidden driver in the back-and the people are participating in an experiment to discover how they'll behave when the car is chauffeuring them around.

At Zenuity-a joint venture between Volvo and Autoliv, a Swedish auto-safet Back in , when the venture capitalist Marc Andreessen said that "software is eating the world," it was still a fresh idea. Now it's obvious that software permeates our lives. From complex electronics like medical devices and autonomous vehicles to simple objects like Internet-connected light- bulbs and thermometers, we're surrounded by software.

At a factory on the outskirts of Brandenburg en der Havel, Germany, bunny-suited technicians are manufacturing the future. The shiny, thin squares they're assembling into flat modules promise to outperform the best solar panels on the market. This advanced medical equipment is designed to keep an ailing person alive. Intravenous fluids drip into the bloodstream, while mechanical ventilators push air into the lungs.

Sensors attached to the body track heart rate, b Schrodinger's famous thought experiment has come to life in a new form because quantum researchers are at the cusp of a long-sought accomplishment: They've spent years battling naysayers who insisted that a quantum computer was an unachievable sci-fi fantasy, and now these researchers are finally beginning to indu Kenya runs on mobile phones.

There are almost 43 million in use by Kenya's nearly 50 million citizens, meaning the East African country has the 33rd highest mobile phone usage in the world. By comparison, it has fewer than 70, fixed landlines. In , shortly before Christmas, Amazon. Some commentators said it was just a publicity stunt. But the notion began to seem less far-fetched when Google revealed its own drone-based delivery effort in , something it calls Project Wing.

And in the early months of , DHL actually integrated d Can building automation systems overcome interoperability problems to assert control over our offices, hotels, and airports? Efforts to make buildings smarter are focusing on cutting costs by streamlining building operations like air conditioning and lighting.

Building automation is critical to these efforts, mainly because it could reduce the annual operating costs of buildings. This article outl The Intel's Core 2 microprocessors, based on the latest nanometer CMOS process technology have more transistors and run faster and cooler than microprocessors fabricated with the previous, nm process generation.

For compute-intensive music, video, and gaming applications, users will see a hefty performance increase. Waymo, the company spun out of Google's self-driving car research, said it would start a commercial Level 4 taxi service by late , although that hadn't happened as of press time.

Today's artificial intelligence systems can destroy human champions at sophisticated games like chess, Go, and Texas Hold 'em.

In flight simulators, they can shoot down top fighter pilots. They're surpassing human doctors with more precise surgical stitching and more accurate cancer diagnoses. But there are some situations when a 3-year-old can easily defeat the fanciest AI in the world: While robots are becoming more diverse and capable, there's one component that hasn't changed much in the past half century: The paper discusses how Kaspersky Lab tracked down the malware that stymied Iran's nuclear-fuel enrichment program.

Bitcoin "miners" are electromagnetic alchemists, effectively turning megawatt-hours of electricity into the world's fastest-growing currency. Their intensive computational activity cryptographically secures the virtual currency, approves transactions, and, in the process, creates new bitcoins for the miners, as payment. And it does another thing, too: It uses an absolutely stunning amount of power Would you pay slightly more for your electricity if you knew it was sourced from photovoltaic panels on your neighbor's roof?

Or, if you are that neighbor, would you use your solar power to charge a battery and dump that energy back onto the grid at peak hours, when the price was highest? The answers to these questions-which depend on how people would behave in an open energy market-are unknown, b Disoriented and dodging cargo trucks exiting a busy overpass, I duck under a bridge and consult the map on my phone, which leads me deeper into a warren of warehouses.

I eventually find Espec Mic Corp. When a new undersea communications cable becomes operational late this year, it will break the record for a key metric: In a single second, its six fiber-optic pairs, stretching roughly 13, kilometers 8, miles between Hong Kong and Los Angeles, will be able to send some terabits in both directions.

That's as much data as you'd find in several hundred Blu-ray d The general process using computer based graphics by which color is being added to black-and-white films is discussed. The differences in techniques used by the various companies adding the colorizing are described. The profitability of this technology is examined.

Other applications are briefly considered. Sometime in , construction on Vineyard Wind, the first major offshore wind farm in the United States, will begin.

Workers will start prepping a pair of undersea substations to be installed about 55 kilometers south of the Massachusetts mainland. A specially equipped trawler will lay undersea transmission cable between the site and a landfall on Cape Cod.

The cable will connect to the switching To produce a better experience for hearing aid wearers, the author's lab at Ohio State University, in Columbus, recently applied machine learning based on deep neural networks to the task of segregating sounds. They have tested multiple versions of a digital filter that not only amplifies sound but can also isolate speech from background noise and automatically adjust the volumes of each separatel Police body cameras are popping up everywhere, often to good effect because both police and suspects normally behave better in their presence.

No wonder these small devices, enthusiastically endorsed by police, politicians, and civil-rights advocates, have generated a burgeoning industry. Yet people know very little about how and why they work, so the intended and unintended consequences of using There was a time when budding inventors were advised to build a better mousetrap.

Nowadays, they'd do rather well to build a better lithiumion battery. These are what power our phones, laptops, portable power tools, an increasing number of cars, even homes. Some places are turning to giant lithium-ion batteries to store energy from solar panels so that it can be used after dark. While lithium-ion This article discusses the development of a memristor and how it works.

2014 Magazine Archive

A memristor is a contraction of a memory resistor and is a two-terminal device whose resistance depends on the voltage applied to it and the length of time that voltage has been applied. This device remembers its history, that is, when you turn off the voltage, the memristor remembers its most recent resistance until the next Moore took a look at his fledgling industry and predicted big things to come in the decade ahead.

In a four-page article in the trade magazine Electronics, he foresaw a future with home computers, mobile phones, and automatic control systems for cars. All these wonders, he wrote, would be driven by a steady doubling, year after year, in the numb You've probably thought of two or three already, but let me add one that I'm sure you haven't.

It's a big obstacle to EVs, and it's rarely remarked upon. Or sitting at a red light when there's no cross traffic at all. Include the evening commute and it is not unusual to spend 3 or 4 hours on the road every day. It seems like hardly a day goes by without some news outlet describing the extraordinary things this technology promises. Most commentators forget, or just gloss over, the fact that people have been working on quantum computing for decades-and without any practical results to show for it.

It's midnight on the North Atlantic, where a massive container ship receives the latest weather report. There's a nasty storm brewing ahead.

Quietly, the ship changes course and speed, to skirt the worst of it and ensure an on-time arrival at its destination. The ship's owners and the harbormaster at its next port of call are advised of the revised route.

And as it nears shore, the giant ship must It anticipates trends in engineering, science, and technology, and provides a forum for understanding, discussion and leadership in these areas.
