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

FPGA devices create compelling business drivers generating a tidal wave of FPGA adoption for the implementation of system PCB designs. Obviously, the time to market advantages and capacity/performance characteristics of FPGA devices have delivered on the promise for a viable alternative to more capital resource intensive custom IC/ASIC solutions as well as a successful consolidation vehicle for standard "off the shelf" components in system design creation.

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.

As Paolo Robuffo Giordano and colleagues at the Max Planck Institute for Biological Cybernetics, in Tübingen, Germany, would have it, scientific research means riding the business end of a giant industrial robot arm while playing video games. But hey -- they produced some serious research on it, which was presented at ICRA 2010.  The CyberMotion Simulator is basically a full motion simulator adapted to a racing car game. Players (or subjects, the researchers prefer to call them) sit in a cabin on a robot arm some 2 meters off the ground and drive a Ferrari F2007 car around a projected track with force-feedback steering wheel and pedals. The aim is to make the experience as realistic as possible without having to buy a real F2007, and to test the simulator with an environment that requires sudden, massive acceleration.

Dennis Hong, a professor of mechanical engineering and director of Virginia Tech's Robotics & Mechanisms Laboratory, or RoMeLa, has created robots with the most unusual shapes and sizes -- from strange multi-legged robots to amoeba-like robots with no legs at all. Now he's unveiling a new robot with a more conventional shape: a full-sized humanoid robot called CHARLI, or Cognitive Humanoid Autonomous Robot with Learning Intelligence. The robot is 5-foot tall (1.52 meter), untethered and autonomous, capable of walking and gesturing. But its biggest innovation is that it does not use rotational joints. Most humanoid robots -- Asimo, Hubo, Mahru -- use DC motors to rotate various joints (typically at the waist, hips, knees, and ankles). The approach makes sense and, in fact, today's humanoids can walk, run, and climb stairs. However, this approach doesn't correspond to how our own bodies work, with our muscles contracting and relaxing to rotate our various joints.

Building a dynamic PHP site requires you to understand how CRUD (create, read, update, delete) functions work. There are a variety of ways to implement these functions include databases, and most commonly through mySQL.  With these functions you can add new entries to the database (registration), view existing entries (retrieve users or fields), update the entries to your table or delete users (who may unsubscribe or permanently delete their accounts.) For a user account based sites, these functions are essential for keeping your user and information database up to date.

This has to have a blog post. =) I've been listening to this album for the past couple of days more or less non-stop... and I love it. Very nice collection of "bass-driven sounds from all over the world". Totally recommended. Check it out! =)

Sony Corp. has developed a highly flexible OLED display that can be rolled around a pencil and continue to operate. The 4.1-inch diagonal isplay is 80-microns thick and offers 432 by 240 by RGB pixels resolution at 121 pixels per inch. It is an organic LED full color display driven by an organic thin-film transistor matrix.

Based on recent technological developments, high-performance floating-point signal processing can, for the very first time, be easily achieved using FPGAs. To date, virtually all FPGA-based signal processing has been implemented using fixed-point operations. This article describes how floating-point technology in FPGAs is not only practical today, but that the processing rates of one trillion floating-point operations per second (teraFLOPS) are feasible and can be implemented on a single FPGA die.

Let’s face it. Most of the gear you use at work or play has multicore processors in it. Your laptop has them (the CPU itself has two cores, and the dedicated graphics processor has many more). That game console in the living room has still more, and even a high-end smartphone typically has a CPU and graphics core on a single chip. Out of sight but definitely not out of mind–particularly if they cease working–are the servers and high-throughput network routers, all which have numerous multicore processors in them. The multiple cores in these devices work in concert to provide quick responses to user queries or to manage the smooth flow of data throughout the office.

In this demo we showcase efforts in MSR to collaborate with external researchers to explore the application of new technologies, specifically Dryad and DryadLINQ, to big data research problems in science. We also highlight our efforts to provide software and services to academics across the world, through the release of Dryad and DryadLINQ free of charge to the research community, along with associated programming guides, user documentation, and code libraries. Dryad is a general-purpose distributed computing engine, more flexible than MapReduce or Hadoop!, that was designed to simplify the task of implementing distributed applications on clusters of Windows computers. DryadLINQ is an abstraction layer which simplifies the process of implementing Dryad-based applications. Microsoft Research is acutely aware of the ubiquity of big data and the challenges this presents. We are offering researchers the tools, resources and collaboration to explore this new area.

AVATAR is by far the most expensive, technically challenging and visually stunning film to date. AVATAR has raised the bar on what is possible from an effects perspective and of course, most of the work and money was because of the software. Weta Digital is the New Zealand effects company that James Cameron used to bring AVATAR alive. Weta Digital also worked on other visually awesome films such as King Kong and the Lord of the Rings trilogy. Weta Digital used more than just one software package. They used half a dozen pieces of software to make AVATAR, as well as some custom built software and applications of its own. Much of the work went into building the virtual world of Pandora, and Weta had to create a virtual camera for James Cameron to use to scout locations and film in the virtual world. Here we take a look at the software that was used to make the movie.

One challenge designers face is the need to translate their algorithms into code for use in embedded targets. The task has proven to be long and prone to error. This article examines how the use of high-level design tools and C code generation capabilities improves the design flow by exploring different use cases and how to reduce the amount of embedded technology expertise required to program embedded targets.

Recent advances in the size and performance of FPGAs, coupled with advantages in time-to-market, field-reconfigurability and lower up-front costs, make FPGAs ideally suited to a wide range of commercial and defense applications [6]. In addition, FPGAs generality and reconfigurability provide important protections against the introduction of Trojan horses during semiconductor manufacturing process[8]. As a result, FPGA applications increasingly involve highly-sensitive intellectual property and trade-secrets, as well as cryptographic keys and algorithms [7].

In Stack Machines, Expression Evaluation, and the Magic of Reverse Polish, I showed how expressions can be evaluated by rewriting them in reverse Polish and translating this into machine-code instructions for a stack machine. I demonstrated with a stack-machine interpreter that I'd written as part of a working model of a Pascal compiler. But as well as expressions, the compiler needs to compile assignments and jumps, so — in my progress towards explaining the compiler — I'm going to extend the machine code so it can handle these. I'll demonstrate by interpreting a program that calculates five factorial.

With the GA release of Scala 2.8 getting very close, David Pollak, the creator of the Scala-based web framework: Lift, has announced a Scala community initiative that  will have an equally large impact on Scala developers.  The Fresh Scala Initiative aims to address the issue of version fragility in the ecosystem.  You may have heard that Scala 2.8 is not binary compatible with the 2.7 branch.  Therefore, some community members have banded together to maintain a repository and provide nightly builds of popular Scala library collections to build against Scala 2.8.
