Fides (Latin: trust) is a guide allowing estimated reliability calculation for electronic components and systems.The reliability prediction is generally expressed in FIT (number of failures for 10 9 hours) or MTBF (Mean Time Between Failures).
A concept closely-related but different [2] to instantaneous failure rate () is the hazard rate (or hazard function), (). In the many-system case, this is defined as the proportional failure rate of the systems still functioning at time t {\displaystyle t} (as opposed to f ( t ) {\displaystyle f(t)} , which is the expressed as a proportion of ...
Annualized failure rate (AFR) gives the estimated probability that a device or component will fail during a full year of use. It is a relation between the mean time between failure ( MTBF ) and the hours that a number of devices are run per year.

A fact box is a simplified display format that presents evidence based data about the benefits and harms of medical treatments, screenings or interventions. [ 1 ] The format has been shown to improve people’s understanding of health-related risk information.
An FiT of ¥42 (US$0.525) per kWh for 10 years for systems less [clarification needed] than 10 kW, and ¥40 (US$0.50) for larger systems, but for 20 years, began on 1 July 2012. The rate was to be reviewed annually, for subsequently connected systems. [95]
Yield in college admissions is the percent of students who enroll in a particular college or university after having been offered admission. [1] [2] It is calculated by dividing the number of students who enroll at a school in a given year by the total number of offers of acceptance sent. The yield rate is usually calculated once per year.
Fit The fit of a commodity is defined by its ability to physically interface or connect with or become an integral part of another commodity. For software, the fit is defined by its ability to interface or connect with a defense article. Function The function of a commodity is the action or actions it is designed to perform. For software, the ...
