The foundation of any laboratory’s reputation is built on confidence in its ability to provide correct and reliable data. ISO/IEC 17025, subclause 4.1.5 d, requires that your management system “have policies and procedures to avoid involvement in any activities that would diminish confidence in…
Clamp-on ultrasonic flow meters are widely used throughout industrial processes in many industries because their noninvasive nature confers inherent advantages over other flow-meter technologies. Material compatibility, contamination, and corrosion risk factors are eliminated. Process integrity is…
Melanoma is one of the less common types of skin cancer, but it accounts for the majority of skin cancer deaths (about 75%). The five-year survival rate for early-stage melanoma is high (98%), but the rate drops precipitously if the cancer is detected late or there is recurrence.
So a great…

In part one of this series, we considered the pros and cons of pressure-decay testing. In part two, we’ll take a close look at a leak-testing method called “differential pressure decay.” This method is similar to simple pressure-decay testing discussed in part one.

Although he’s not one for clichés, Rus Emerick, process improvement specialist at Schneider-Electric, endorses this one: “The whole is greater than the sum of its parts.”
This concept, which dates back to Aristotle, is at the core of an approach called functional analysis that has implications…

In sawmills, optimization is an in-process procedure that maximizes output of the highest-value board size and quality from the limited and environmentally valuable input of randomly shaped logs. During the optimization process, 3-D profiles of each raw board are analyzed before positioning saws.…
(The Modeling Agency: Pittsburgh) -- The Modeling Agency (TMA), a data-mining training, consulting, and solutions company, announces a restructuring of its popular “Predictive Analytics & Data Mining” course series. The two-course series offers two distinct orientations with complementary…

For decades we were taught to believe that if you ever wanted to measure anything properly, you needed a coordinate measuring machine (CMM). A couple of decades ago, portable arms were released and although they were novel, nothing could compare to the rigidity and accuracy of three linear scales…
X-ray fluorescence spectrometry was done directly on the paintings in the Louvre Museum.

During the past 20 years it has become fashionable to condemn measurement processes that are less than perfect. Yet the reality is that we must always use imperfect data. Given this fact of life, how can we ever know if a measured item is or is not within the specifications? Put another way, how…

There are many reasons why firms need to model the exterior contour of existing aircraft outer mold lines (OML). Most aircraft flying today were not designed in a modern 3-D CAD system. Even with a current 3-D digital design, the actual as-built contour deviates from the intended shape, at least…

Not too long ago, when you wanted a product to be leak-proof, you simply put it under water, made sure it didn’t bubble, and thereby concluded there were no leaks. Such “bubble testing” takes time and depends on the operator’s ability, making it totally inappropriate for the modern production…
