Measurement systems analysis (MSA) has been applied in different aspect of industrial assessments to evaluate various types of quantitative and qualitative measures. Qualification of a measurement system depends on two important features: accuracy and precision. Since the capability of each quality system is severely related to the capability of its measurement system, the weakness of the two...

Reducing measurement errors in multiqubit quantum devices is critical for performing any algorithm. Here we show how to mitigate by a classical postprocessing of the measured outcomes. Our techniques apply experiment where outcomes are used computing expected values observables. Two error-mitigation schemes presented based on tensor product and correlated Markovian noise models. Error rates par...

With abundance of water on the earth the fresh water sources are limited. So a need arises to precisely measure this resource in many industrial and commercial places wirelessly. Many measurement techniques for liquid such as float, pressure gauge, ultrasonic and radar are available. Floats and pressure gauge suffer from cumulative error which increases with time whereas ultrasonic and radar gi...

What is the set of possible values of a measurement error? In the majority of practical applications, an error is caused not by a single cause; it is caused by a large number of independent causes, each of which adds a small component to the total error. As a result, we get a geometric description of the area of possible values of error. In this paper, we formulate the known result (for 1-dimen...
