Characteristic life
|
In weibull and reliability/failure time analysis the characteristic life is defined as the point in time where 63 2 percent of the population will have failed; this point is also equal to the respective scale parameter b of the two-parameter weibull distr

Reliability, английский
- Надежность
- Engineering, analysis and planning планирование и технический анализ надежности
- Достоверность
- Достоверность; надежность
- Надёжность, безотказность (в эксплуатации)
- Надежность. степень, с которой эксперимент, испытание или методика измерений дают точные результаты в повторяющихся испытаниях [36].
- Electric system reliability has two components
- Generally, invulnerability to potentially corrupting influences. specifically
- The likelihood of a computer system or device continuing to function over a given period of time and under specified conditions.
- Reliability has two components: adequacy and security. the former involves ensuring that supply is available to meet demand at dispersed points of consumption. in network industries, storage can be costly-requiring adequate capacity to transportservices (electricity or telecommunications signals) to final consumers. security is characterized by the system’s ability to withstand sudden, unanticipated disturbances, as when a transmission line suddenly becomes unavailable or particular links or production nodes are disrupted.
- In general: reliability is the degree of performance according to imposed standards or expectations. electrical reliability is the absence of unplanned interruptions of the current by, for example, shortage of supply capacity or by failures in parts of the grid. reliability differs from security and from fl uctuations in power quality due to impulses or harmonics. renewable energy – see energy
- "the ability of an item to perform a required function under given conditions for a given time interval.
- A measure of how trustworthy a test is.
- Being dependable or consistent
- Being dependable or consistent having the same results after many tests
Population, английский
- A definable set of individual units to which the findings from statistical examination of a sample subset are intended to be applied. the population will generally much outnumber the sample. in re-randomisation statistics the process of applying inference
- See stock.
- A collection of units being studied. units can be people, places, objects, epochs, drugs, procedures, or many other things. much of statistics is concerned with estimating numerical properties (parameters) of an entire population from a random sample of units from the population.
- A group or number of people living within a specified area or sharing similar characteristics (such as occupation or age).
- Население; народонаселение; генеральная совокупность (в выборочном наблюдении); популяция (биол)
- Население
- 1. the number of people living in a country or town population statistics show that the birth rate is slowing down. the government has decided to screen the whole population of the area. 2. the number of patients in hospital the hospital population in the area has fallen below 10,000.
- Популяция
- Население; популяция -
- Популяция. в клинических исследованиях совокупность субъектов, обладающих какими-либо одинаковыми признаками (пол, возраст, диагноз).
- Население; популяция
- Any group of individuals, usually of a single species, occupying a given area at the same time; groups of organisms with homologue (same) alleles. p. cycle: changes in the numbers of individuals in a population which repeatedly oscillate between periods of high and low density. p. density: allowing a mathematically precise reflection - pd. • absolute: pd = number of individuals/unit area or volume [1/m2] or [1/m3] • relative: pd allows only a simple comparison (pd <, =, >, ? etc.). p. dynamics: the variations in time and space in the sizes and densities of populations; distribution due to changing food resources - the stability of a population depends upon abiotic factors, intraspecific competition (density dependent), natality, mortality etc. p. ecology: the study of the variations in time and space in the sizes and densities of populations, and of the factors causing those variations. p. fluctuation: variations over time in the size of a population. p. growth: is zero, when the birth rate equals the death rate (see carrying capacity). nt+1 = nt + r nt, current number of individuals r = (natality + immigration) - (mortality+emigration) r, intrinsic rate of growth (see density) p. pyramid: a means of illustrating the age structure of a population diagrammatically, by placing the youngest age class at the base and stacking successive age classes above it. p. regulation : a tendency in a population for some factor to cause density to increase when it is low and to decrease nt, momentary number of individuals when it is high. n0, number of individuals at start
- Generally, a collection of individuals with common characteristics. in statistics, a potentially infinite collection of independent (->independence) units that include all units of a specified type with attention paid only to the agggregate (->aggregation) property of the collection. a sample of data drawn from this population is a subset of the units constituting this population and scientific generalizations from such samples are limited by the size of the population originally specified (->model, ->representation).
- The process of scanning content to compile and maintain an index.
- Fish of the same species inhabiting a specified geographic area.
