This year's annual New York press briefing by the Edison Electric Institute, the organization representing investor-owned utilities, naturally was devoted to the smart grid, the hot topic of the day. Most notable, actually, was the absence of anything really new to report, which confirmed expectations that the smart grid will begin to prove itself next year at the earliest--or not. This was not the first EEI briefing devoted to smart grid prospects. Last year's briefing was devoted almost entirely to the smart meter avalanche, and a year or two before that much was made of Xcel Energy's SmartGridCity experiment in Boulder, Colorado. I reminded EEI president Thomas Kuhn of the Boulder briefing and pointed out that the experiment appears now to have been a failure. Kuhn did not dispute that and said it appears the problem in Boulder was that the target population was just too affluent: Despite the known green-mindedness of Boulderites, a major factor in Xcel's selecting the small city for its smart grid test run, it seems most of them do not care all that much about the modest monetary savings they stand to make from paying attention to electricity usage signals.

Researchers at Purdue University have developed a new design employing carbon nanotubes and small copper spheres that wicks water passively towards hot electronics that could meet the challenges brought on by increasing frequency speeds in chips. The problem of overheating electronics is well-documented and in the past the issue has been addressed with bigger and bigger fans. But with chip features shrinking below 50 nanometers the fan solution is just not cutting it. The Purdue researchers, led by Suresh V. Garimella, came up with a design that uses water as the coolant liquid and transfers the water to an ultrathin thermal ground plane. The design naturally pushes the water through obviating the need for a pump and through the use of microfluidic design is able to boil the water fully, which allows the wicking away of more heat.

That age-old question, "where did life on Earth start?" now has a new answer. If the life between the mica sheets hypothesis is correct, life would have originated between sheets of mica that were layered like the pages in a book.

High Level Synthesis Architectural Optimization Basics In part 1 of this article we introduced basic filter bank theory and used the Synplify DSP High Level Synthesis (HLS) tool to implement an example filter bank into three alternative architectures. In part 2 we dive deeper into these three architectures to better understand how these filters work. We will also examine the HLS optimizations we applied and the resulting benefits. Example Filter Bank Review Before we proceed, let's quickly review our filter bank example. Our example, shown in Figure 1, is a size 16 DFT filter bank. The color scheme shows the sample rate change where a 16 MHz input sample rate (red) has been chosen and the output sample rate is downsampled by 16 (green).

The "kid-size" humanoid league at the RoboCup features standardized humanoid robots that teams write software for. The reigning 2009 champs, from Technische Universitat Darmstadt, worked on making shots and passes quicker in this year's matches. Watch the video highlights and see if their strategy paid off.

Now that Harry's the prime suspect in the killings he was charged to solve even his best friend doesn't trust him. And it could cost Lt. Murphy her life! Can Harry reach her in time?The Dresden Files: Storm Front rolls on with its hallmark mix of mystery and adventure that made Jim Butcher's novels a smash hit!

No, we're not talking about a Wonder Woman-type of invisible plane, but rather one that becomes very difficult to detect with radar. The Israel-based Ynetnews is reporting that an Israeli company called Nanoflight has successfully run a test on dummy missiles that were painted with the nano-enabled coating and have shown that radar could not pick them up as missiles.

A shielded transformer is a two-winding transformer, usually delta"star connected and serves the following purposes: Voltage transformation from the distribution voltage to the equipment's utilization voltage. Converting a 3-wire input power to a 4-wire output thereby deriving a separate stable neutral for the power supply wiring going to sensitive equipment. Keeping third and its multiple harmonics away from sensitive equipment by allowing their free circulation in the delta winding. Softening of high-frequency noise from the input side by the natural inductance

In traditional short-haul microwave transmission (that is, line-of-sight microwave transmissions operating in the 18 GHz and 23 GHz radio bands),RF design engineers typically are concerned with signal aspects such as fade margins, signal reflections, multipath signals, and so forth. Like an accountant seeking to balance a financial spreadsheet, an RF design engineer normally creates an RF budget table, expressed in decibels (dB), in order to establish a wireless design. Aspects like transmit power and antenna gain are registered in the assets (or plus) column, and free space attenuation, antenna alignment, and atmospheric losses are noted in the liabilities (or minus) column. The goal is to achieve a positive net signal strength adequate to support the wireless path(s) called for in the design.

In addition to voice connectivity, digital cellular wireless networks such as GSM and its enhancement, GSM-EDGE, can now provide increased data speeds up to a (theoretical) limit of 384ﾠKbps. Third generation mobile networks, such as CDMA2000 and WCDMA or UMTS (Universal Mobile Telecommunications Standards) and TD-SCDMA (China only) are currently being deployed worldwide. These systems offer services such as video streaming, Internet browsing and, by using a technique called High Speed Packet Access (HSPA), they can in theory deliver downlink speeds up to 14,4 Mbps.

In 1975, future Hall of Famer Roger Staubach had the football but little else in a playoff game against the Minnesota Vikings. Behind by four points at midfield with 24 seconds to go, the Dallas Cowboys quarterback closed his eyes, threw the ball as hard as he could, and said a Hail Mary. (For you soccer fans, this would be like David Beckham taking a shot on goal from midfield late in injury time.)

Cellphone carriers are racing this year to implement 4G wireless networks so that future smartphones will have access to a fire hose of data. But the towers and infrastructure the carriers are putting in place may ultimately facilitate as many connections with appliances and electric meters as they do downloads of movies and music. The electricity grid, in other words, may be jumping from no G to 4G—and rather soon, according to analysts.

Humans aren't the only ones playing soccer right now. In just two days, robots from world-renowned universities will compete in Singapore for RoboCup 2010. This is the other World Cup, where players range from 15-centimeter tall Wall-E-like bots to adult-sized advanced humanoids. The RoboCup, now in its 14th edition, is the world’s largest robotics and artificial intelligence competition with more than 400 teams from dozens of countries. The idea is to use the soccer bots to advance research in machine vision, multi-agent collaboration, real-time reasoning, sensor-fusion, and other areas of robotics and AI. But its participants also aim to develop autonomous soccer playing robots that will one day be able to play against humans. The RoboCup's mission statement:

A test circuit built with nanowires of silicon could point the way to much smaller transistors, say the IBM researchers who created it. Researchers from IBM’s Thomas J. Watson Research Center announced today at the annual Symposium on VLSI Technology, in Honolulu, that they have built a ring oscillator out of field-effect transistors (FETs) based on nanowires with diameters as small as 3 nanometers. The oscillator—is composed of 25 inverters using negative- and positive-channel FETs. The device, which demonstrated a delay of just 10 picoseconds per stage, shows that engineers can build a working circuit from transistors with much shorter channel lengths than today’s devices. Current flows through an FET’s channel under the control of the device’s gate. Scaling down the channel length will be critical if the dimensions of circuits on silicon chips are to continue to shrink, says Jeffrey Sleight, a senior technical staff member at IBM.

By now most residents of the Dallas / Fort Worth area are aware of the giant, 35,000 lbs steel robot that towers over DART's Deep Ellum rail station. Robot builders may also be aware of the robot from coverage in Robot Magazine. Now, the rest of the world is taking notice because the prominent art organization, Americans for the Arts, has included the Dallas Robot, known officially as Traveling Man, on its list of 40 Best Public Art Works in the US and Canada. Read on to learn more about Traveling Man and see more photos of the big robot and little chrome friends.So what's the story behind this giant robot? A combination of opportunities and influences led to its creation. Dallas Area Rapid Transit or DART as it's known locally, was expanding into the Deep Ellum area with a new rail line and a Deep Ellum rail station. Deep Ellum is the historic Dallas arts district from which have come a long list of musical and visual artists. The area is also well known for its many public art pieces, many improvised in local do-it-yourself fashion. Painters and sculpters often create art on the exterior of their own or other buildings in the area.

The e-reader market took the company E-Ink and its low-power, easy-on-the-eyes digital paper technology mainstream. But no one says E-Ink is perfect; the displays, to date, don’t do flexibility or full color well. And they aren’t cheap enough to move into budget-conscious applications, like the long-dreamed of grocery store shelf tags that could be updated remotely to display new prices. E-Ink and its brethren continue to advance down their technology development paths. But a startup company based in Saratoga, Calif., says they’re heading in the wrong direction.

In mathematics, computer science, and related subjects, an 'algorithm' is an effective method for solving a problem expressed as a finite sequence of instructions. Algorithms are used for calculation, data processing, and many other fields. (In more advanced or abstract settings, the instructions do not necessarily constitute a finite sequence, or even a sequence; see, for example, "nondeterministic algorithm".) Each algorithm is a list of well-defined instructions for completing a task. Starting from an initial state, the instructions describe a computation that proceeds through a well-defined series of successive states, eventually terminating in a final ending state. The transition from one state to the next is not necessarily deterministic; some algorithms, known as randomized algorithms, incorporate randomness. [source = Bing Reference]
