The most advanced production car in the world, the Tesla, is more a computer than a car. The old heart of the automobile replaced by batteries, chips, circuit boards and wiring. These days, a car will have 70 to 100 electronic control units (ECUs), which are based on microprocessors that sit on boards and boxes scattered throughout the vehicle, all connected with wires. For pure mechanical engineers, who in their heydays were at home among gears, pistons and shafts, life has become more complica… …read moreContinue reading →
Marine and terrestrial species inhabit vastly different ecosystems, but they share one of the primary patterns of biodiversity on the planet. The numbers of species of both groups increase toward the equator, with fewer species in temperate, higher latitudes and more in the tropics. …read moreContinue reading →
The oldest surviving species of vertebrates, such as the cane toad and the California sea lion, which have endured past extreme environmental events, will be more likely to adapt to future climate changes than younger species, such as the European hamster, according to a study published in the open access journal BMC Evolutionary Biology. These species include those with various color morphs; those which give birth to live young; and/or which live at low latitudes. …read moreContinue reading →
United Kingdom–based Cambashi is a consulting firm that performs market research that analyzes how business issues in industries like energy, utilities, construction and manufacturing are impacted by novel use of information technologies. They have a Web-based industry curriculum and recently delivered an excellent webinar that focused on clarifying and assessing the differences in merger and acquisition behavior of major engineering software companies. By breaking down data from their Cam… …read moreContinue reading →
Researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have challenged understanding of a key element in fusion plasmas. At issue has been an accurate prediction of the size of the “bootstrap current”—a self-generating electric current—and an understanding of what carries the current at the edge of plasmas in doughnut-shaped facilities called tokamaks. This bootstrap-generated current combines with the current in the core of the plasma to produce a magnetic field to hold the hot gas together during experiments, and can produce stability at the edge of the plasma. …read moreContinue reading →
We are happy to announce the availability of MATLAB scripts for our data acquisition starter kits that specifically support our low-cost starter kit models DI-145, DI-149, DI-155, and DI-245. MATLAB is an analytical tool that is especially popular at the university level, and anywhere signal analysis is performed. The scripts we’ve released allow data to be acquired from the target instruments and streamed into a MATLAB matrix, where it’s available for evaluation using the application’s powerful tools. An added feature is that these scripts do not require MathWorks’ Data Acquisition Toolbox, an individual license for which costs $1,000. The scripts operate with a standard license without additional add-ins and their associated cost burden.
In addition to scripts supporting real time data acquisition, we’ve also released one that exports data into a matrix from a recorded WinDaq data acquisition file (*.WDQ).
MATLAB Script Overview
Real time data acquisition from a supported DATAQ Instruments Starter Kit to a MATLAB matrix is actually the result of two scripts working in concert. The main is a script targeted for a specific data acquisition hardware device. The second script is shared by all devices and acts as an event handler for data …read moreContinue reading →
