There is a long history of attempts at replicating neural systems either in software or in conventional semiconductors, such as the FACETS project (not to mention the creation of conventional logic gates from lab-grown biological neurons!) According to a USC Viterbi news release, researchers at the BioRC project, whose goal is research on an artificial cortex, have succeeded in creating a functioning synapse from carbon nanotubes. The new research was presented by Alice C. Parker in the paper "A biomimetic fabricated carbon nanotube synapse for prosthetic applications" at the Life Science Systems and Applications Workshop in April 2011. (unfortunately the actual paper is behind a paywall but the abstract is readable). An earlier paper, "A Biomimetic Carbon Nanotube Synapse Circuit", describes the proposed design of synapse including schematics and comparison with biological neural

Friday nights on Syfy Channel this past fall wasn’t the only place to get a fix of Stargate Universe. Each week MGM also released new kino webisodes — short scenes that complement the TV show. Some of these are general introductions to the ship and its (reluctant) new crew; others tie in directly to an episode, functioning as something of a deleted scene.

In case you missed them, below you can see all 22 kino webisodes released during the first half of the season! The kino webisodes were directed by Ivon Bartok (friend of the site), with a total of 30 installments to be released during SGU’s first season.

The consumer handheld market is growing by leaps and bounds. With more processing power and increased support for more applications, portable products are cross-pollinating with traditional computing systems even as the product life cycle has decreased considerably in this market segment. As a result, especially in this era of economic slowdown, it is imperative that new products meet the time-to-market window to gain maximum acceptance. A decrease in product life cycles requires a reduced development cycle and an increased emphasis on reusability and reprogrammability. The emerging handheld market is also seeing interesting trends in which each individual device in a family has lower volumes but there is more customization across the series of devices, effectively upping the total unit volumes. The key challenge then becomes how to develop a system that is widely reusable and also customizable. These requirements have led designers increasingly to turn to the FPGA for handheld-product development. The FPGA has become more powerful and feature-rich, while gate counts, area and frequency have increased. FPGA development and turnaround cycles are considerably shorter than those of custom ASICs, and the added advantage of reprogrammability can make the FPGA a more compelling solution for handheld embedded systems.

Today’s blog entry may be offensive to sensitive Scotsmen and/or Scotswomen.  Reader discretion is strongly advised – especially if you’ve ever worn a kilt. Yesterday, on my way to dinner with Marty and co., I stopped by my local butcher shop and picked up a fresh haggis, determined to finally sample the Scotland’s national dish (I thought it was the deep-fried chocolate bar.  That shows you how much I know).  For those of you not in the know, haggis is comprised of various minced sheep’s innards (ie. lungs, liver, and heart), beef and/or mutton fat, oatmeal, onion, and spices stuffed into a sheep’s stomach, served steamed or boiled with a side of turnips and rutabagas.

Researchers at Purdue University have developed two new techniques for computer-vision technology that mimic how humans perceive three-dimensional shapes.The techniques, heat mapping and heat distribution, apply mathematical methods to enable machines to perceive three-dimensional objects by mimicking how humans perceive three-dimensional shapes by instantly recognizing objects no matter how they are twisted or bent, an advance that could help machines see more like people.

The first textbook of its kind, Programming Massively Parallel Processors: A Hands-on Approach launches today, authored by Dr. David B. Kirk, NVIDIA Fellow and former chief scientist, and Dr. Wen-mei Hwu, who serves at the University of Illinois at Urbana-Champaign as Chair of Electrical and Computer Engineering in the Coordinated Science Laboratory, co-director of the Universal Parallel Computing Research Center and principal investigator of the CUDA Center of Excellence. The textbook, which is 256 pages, is the first aimed at teaching advanced students and professionals the basic concepts of parallel programming and GPU architectures. Published by Morgan Kaufmann, it explores various techniques for constructing parallel programs and reviews numerous case studies. With conventional CPU-based computing no longer scaling in performance and the world’s computational challenges increasing in complexity, the need for massively parallel processing has never been greater. GPUs have hundreds of cores capable of delivering transformative performance increases across a wide range of computational challenges. The rise of these multi-core architectures has raised the need to teach advanced programmers a new and essential skill: how to program massively parallel processors.

The first part of this white paper explores the basic concepts behind HDMI, the markets it serves and its leadership role in multimedia interfaces. This is followed by a tutorial on the new capabilities of HDMI 1.4 and their role in providing a richer, more straightforward user experience. Next, we'll explore a series of user case scenarios that illustrate how the HEAC feature can simplify cabling requirements between digital home multimedia devices. The last portion of this paper discusses the architectural considerations and technical details involved with incorporating the Ethernet and Sony/Philips Digital Interconnect Format (S/PDIF) standards into the HDMI system-on-chips (SoCs) to support the HEAC feature.

William Bell may currently be stuck Over There, but he could soon be Over and Out. According reports, Leonard Nimoy is set to retire from acting – but when, and what does this mean for his part on Fringe? Head past the jump to find out. Warning, we feel that his retirement will be general knowledge, but the details of which are below the jump for a reason -  do not click link if you don’t want to know the details! In an interview with Toronto Sun, Leonard Nimoy revealed he will be bringing the curtain down on his 60 year acting career. Having just shot his final appearance as William Bell for the Fringe Season 2 finale, Nimoy says he plans to “go out on a positive note”.

Last week, Nanowerk’s Spotlight piece covered recent research in which Swiss researchers demonstrated that they could remove metal ions, steroid drugs and proteins from blood by using nanomagnets. The nanomagnets are basically carbon-coated iron carbide at the nanoscale (an average diameter of 30 nanometers) and are functionalized with linker molecules that attract the target material in the blood.

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 animal world has been a source of inspiration for many robotic designs as of late, as who better to ask about life-like movements than mother Nature herself? Up until now, though, these designs had been mostly focused on small critters, like cockroaches, and simulating properties such as adaptability and speed. But what happens when we start looking at bigger and stronger animals? Like, say, an elephant? Well, Festo’s Bionic Handling Assistant is what happens. This innovation might seem like just another robotic arm at first glance, but the video demonstrates quite vividly how this design is such a big improvement over previous versions. Modeled after the elephant’s mighty trunk, this arm possesses great dexterity, flexibility and strength; operating with smooth, yet firm motions, and can pick up and move any kind of object from one place to another. It’s FinGripper fingers give it “an unparalleled mass/payload ratio”, and it has no problem twisting, assembling and disassembling things, such as the experimental toy in the video.

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.

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]
