Test engineers in industries ranging from aerospace and defense to consumer electronics are facing the challenge of testing increasingly complicated designs with shrinking timelines and budgets. To address these issues, engineers and scientists are incorporating new test and measurement technologies that are capable of meeting complex design requirements without raising costs. National Instruments (NI) has identified five trends it anticipates will significantly influence the test and measurement industry over the next three years.”Companies are turning to the latest technologies including PXI, FPGAs and multicore processors to develop high-performance test systems that can meet consumer demand for higher-quality products,” said Eric Starkloff, National Instruments director of test product marketing.

“Fortunately, more technology vendors are developing industry-standard tools capable of solving problems that previously depended on expensive, dedicated test systems.”

This undated handout photo provided by IBM and the Feature Photo Service shows lead engineer Don Grice of IBM inspecting the world’s fastest computer, nicknamed “Roadrunner”, in the company’s Poughkeepsie, N.Y. plant. Scientists unveiled the world’s fastest supercomputer on Monday, June 9, 2008, a $100 million machine that for the first time has performed 1,000 trillion calculations per second in a sustained exercise. The technology breakthrough was accomplished by engineers from the Los Alamos National Laboratory and the IBM Corp. on a computer to be used primarily on nuclear weapons work, including simulating nuclear explosions.

These cards Comply with MD1 low profile card size, suit slim line PC Applications.

One to eight port cards are available for RS-232 applications; one or two port cards for RS-422/485. Use RS-422 to extend range, RS-485 to extend range and provide multi-drop ability.DB9 connectors offer positive thumbscrew locking, more robust than phone jack connectors. One port model has port on faceplate. Two, four and eight port models include fan-out cables.Operate on both 3.3 and 5 volt PCI, as well as PCI-X buses. Maximum baud rate on most models is 460.8 kbps (Model QSCLP-100 has a maximum baud rate of 921.6 kbps). Support Win 95, 98, ME, NT, 2000, XP, Linux and OS/2.Unique Benefits:

• Low profile to fit slim-line PCs
• Available with 1 to 4 ports

Descartes

This is a Windows application for drawing graphs of mathematical functions. See screenshots below for an idea of what it can do. You do not choose from a limited set of offered functions - an expression evaluator can deal with an extremely wide range of expressions from simple polynomials, trigonometric, hyperbolic, exponential terms, differentials and integrals, and sums and products of series.

Zelscope is a Windows software that converts your PC into a dual-trace storage oscilloscope and spectrum analyzer. It uses your computer’s sound card as analog-to-digital converter, presenting a real-time waveform or spectrum of the signal - which can be music, speech, or output from an electronic circuit. Zelscope features the interface of a traditional oscilloscope, with conventional gain, offset, timebase, and trigger controls. As a real-time spectrum analyzer, Zelscope can display the amplitude and phase components of the spectrum.

.. The free space simulation that lets you explore our universe in three dimensions. Celestia runs on Windows, Linux, and Mac OS X.

Unlike most planetarium software, Celestia doesn’t confine you to the surface of the Earth. You can travel throughout the solar system, to any of over 100,000 stars, or even beyond the galaxy.
All movement in Celestia is seamless; the exponential zoom feature lets you explore space across a huge range of scales, from galaxy clusters down to spacecraft only a few meters across. A ‘point-and-goto’ interface makes it simple to navigate through the universe to the object you want to visit.
Celestia is expandable. Celestia comes with a large catalog of stars, galaxies, planets, moons, asteroids, comets, and spacecraft. If that’s not enough, you can download dozens of easy to install add-ons with more objects.

VMD is designed for the visualization and analysis of biological systems such as proteins, nucleic acids, lipid bilayer assemblies, etc. It may be used to view more general molecules, as VMD can read standard Protein Data Bank (PDB) files and display the contained structure. VMD provides a wide variety of methods for rendering and coloring a molecule: simple points and lines, CPK spheres and cylinders, licorice bonds, backbone tubes and ribbons, cartoon drawings, and others. VMD can be used to animate and analyze the trajectory of a molecular dynamics (MD) simulation. In particular, VMD can act as a graphical front end for an external MD program by displaying and animating a molecule undergoing simulation on a remote computer.
