When doctors destroy a liver tumor with heat instead of surgery, the entire battle is won or lost by millimeters. Thermal ...

MIDDLETOWN, Conn., - Inductive eddy current technology is an extremely versatile non-contact method for measuring an object’s position, distance, or vibration. Unaffected by environmental contaminants ...

Process Engineer Richard Kasica of NIST’s Center for Nanoscale Science and Technology holds a wafer of the type typically produced in the plasma-enhanced chemical vapor deposition chamber. A new study ...

There are three major sources of measurement error: gross, systematic, and random. Gross error is people-caused error. Causes of people error are as diverse as people ...

Accurate measurement is something most people assume happens automatically. Whether weighing ingredients for a recipe, checking room temperature, measuring a room for furniture, or relying on a scale ...

In order to measure the mechanical properties of materials in compression, tension, bending or torsion, a universal testing machine is utilized. This article outlines the two different types ...

Test instruments such as oscilloscopes and DMMs (digital multimeters) often let you get the measurement results you need with just the press of a button. But the number on a meter's display or the ...

The venerable Kelvin-sensing circuit, or four-terminal measurement circuit, minimizes measurement errors that your test equipment and test leads can impose. It is named for William Thomson, Lord ...

On-demand qubit-state initialization is a prerequisite for quantum computation. We demonstrate such a protocol in a device consisting of fixed-frequency transmon qubits pair-wise coupled via tunable ...

One of the most striking features of quantum physics is that certain properties cannot both be known or measured with arbitrary precision at the same time. Every measurement may inevitably affect the ...
