Definition and Importance: In research, reliability means "repeatability" or "consistency" and is an important part of measurement quality. A reliable measurement tool should give the same result in multiple measurements. It is the basis of measurement ...

Curricular validity is usually measured by a panel of curriculum experts. It’s not measured statistically, but rather by a rating of “valid” or “not valid.” A test that meets one definition of validity might not meet another. For example, a test might have curricular validity, but not...

The definition of reliability of knowledge-updating in network knowledge resource management system (NKRM system for brief) has been given in this paper, which has important reference value to the evaluation of NKRM system. Besides, two kinds of models in NKRM system have been introduced. And ...
For example, if X is a random variable of lognormal distribution (i.e., X ∼ LN(μX, σX)), X can be transformed into a random variable U of standard normal distribution following the definition of lognormal distribution shown in Eqs 10.63b and 10.63c. In other words, the cumulative...

The proposed review of investigations in drone swarm reliability analysis shows that there are gaps in the development methods for the definition and computation of basic indices and measures of these systems. In this paper, the availability and two types of importance measures (structural importance ...
