Made for engineers, researchers, quality professionals, Six Sigma practitioners or other experimenters, this software is engineered to help experiment design. It is powerful enough for a veteran statistician, but intuitive enough for a beginner. Its minimum-run two-level factorial design lets users screen for main effects with a low number of experimental runs. The new version's analysis tools include the Pareto chart of effects, which allows users to see vital few effects compared to the trivial many. Central composite designs based on a minimum-run core are very efficient for response surface methods, and sophisticated experiments for mixture-in-mixture designs involving separate formulations that may interact. New RSM graphics feature full-color graduated or banded contour and 3D surface plots. Actual response collections are marked on the 3D surface graphs with lollipop points, and responses can be predicted at any place on the response surface plot using the new crosshairs window. The software also has design creation tools, enhanced design augmentation ability, analysis capabilities, diagnostic capabilities, more improvement to the user interface, options for design evaluation and new import/export tools. The software comes with a printed Getting Started guide and easy-to-follow tutorials in Adobe PDF format. Stat-Ease offers free technical support and access to statistical consultants who are experts on experimental design. Design-Expert 7.0 retails for $995, and a free 45-day trial version is available.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
