Any region marking the area where one formula is used at smaller values of the independent variable (say, x, or z) and another formula is used at larger values of the independent variable. In this book, transition or interpolation formulas are suggested so the solution varies smoothly across the transition region.

The fraction of radiant energy that is transmitted from the radiating object through the atmosphere to a target. The transmissivity is reduced due to the absorption and scattering of energy by the atm [..]

Openness of an organization with regard to sharing information about how it operates.

A bidirectional rectifier (essentially two SCRs in parallel) that function as an electrically controlled switch for ac loads and having an npnpn structure that can be triggered into either forward or [..]

Charge separation caused by rubbing of surfaces, creating triboelectricity.

Expanding the traditional business-reporting framework to take into account environmental and social performance in addition to financial performance.

The ratio of the turbulent velocity to the mean wind speed (e.g., su/u).

A scheduled shutdown period when planned inspection, testing, and preventive maintenance, as well as corrective maintenance such as modifications, replacements, or repairs is performed.

The probability the fault event exists at a specified time.

A measure, often quantitative, of the degree of doubt or lack of certainty associated with an estimate of the true value of a parameter.
