Generation time. In population biology and demography, generation time is the average time between two consecutive generations in the lineages of a population. In human populations, generation time typically has ranged from 20 to 30 years, with wide variation based on gender and society. [1][2] Historians sometimes use this to date events, by ...
The doubling time is the time it takes for a population to double in size/value. It is applied to population growth, inflation, resource extraction, consumption of goods, compound interest, the volume of malignant tumours, and many other things that tend to grow over time. When the relative growth rate (not the absolute growth rate) is constant ...
The mean generation time is equal to the sum of the mean latent period and one-half of the mean infectious period, given that infectiousness is evenly distributed across the infectious period. [1] Since the precise moment of infection is very difficult and almost impossible to detect, the generation time is not properly observable for two ...
Generation of primes. In computational number theory, a variety of algorithms make it possible to generate prime numbers efficiently. These are used in various applications, for example hashing, public-key cryptography, and search of prime factors in large numbers. For relatively small numbers, it is possible to just apply trial division to ...
Reactor time behavior can be characterized by weighing the prompt and delayed neutron yield fractions to obtain the average neutron lifetime, Λ=l/k, or the mean generation time between the birth of a neutron and the subsequent absorption inducing fission. [5] Reactivity, ρ, is the change in k effective or (k-1)/k. [3]
Capacity factor. US EIA monthly capacity factors 2011-2013. The net capacity factor is the unitless ratio of actual electrical energy output over a given period of time to the theoretical maximum electrical energy output over that period. [1] The theoretical maximum energy output of a given installation is defined as that due to its continuous ...
The period life table represents mortality rates during a specific time period for a certain population. A cohort life table, often referred to as a generation life table, is used to represent the overall mortality rates of a certain population's entire lifetime. They must have had to be born during the same specific time interval.
The serial interval in the epidemiology of communicable (infectious) diseases is the time between successive cases in a chain of transmission. [1] The serial interval is generally estimated from the interval between clinical onsets (if observable), in which case it is the 'clinical onset serial interval'. It could in principle be estimated by ...
