Reliability engineering is a sub-discipline of systems engineering that emphasizes the ability of equipment to function without failure. Reliability is defined as the probability that a product, system, or service will perform its intended function adequately for a specified period of time, OR will operate in a defined environment without failure. [1]
Among the most common measures of reliability are the mean time to first failure, the mean time between failures, and the failure rate per unit time. Because these measures require a product to be in use for a specified period, they are more relevant to durable goods than to products and services that are consumed instantly.
Common law legal systems can include a statute specifying the length of time within which a claimant or prosecutor must file a case. In some jurisdictions (e.g., California), [2] a case cannot begin after the period specified, and courts have no jurisdiction over cases filed after the statute of limitations has expired.
A fixed-term contract is a contractual relationship between an employee and an employer that lasts for a specified period that is determined in advance. These contracts are usually regulated by countries' labor laws, to ensure that employers still fulfill basic labour rights regardless of a contract's form, particularly unjust dismissal.
It includes logistics time, ready time, and waiting or administrative downtime, and both preventive and corrective maintenance downtime. This value is equal to the mean time between failure divided by the mean time between failure plus the mean downtime (MDT). This measure extends the definition of availability to elements controlled by the ...
Prevalence is the number of disease cases present in a particular population at a given time, whereas incidence is the number of new cases that develop during a specified time period. [2] Prevalence answers "How many people have this disease right now?" or "How many people have had this disease during this time period?".
The United States Food and Drugs Administration is warning pet owners about a common medication given to pets to treat arthritis. The F.D.A. now says that the drug Librela may be associated with ...
Incidence proportion (IP), also known as cumulative incidence, is defined as the probability that a particular event, such as occurrence of a particular disease, has occurred in a specified period: [1]
