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.
Transmission, английский
- Passage of electromagnetic radiation through a medium.
- Transmisión
- The property in a merchantman, or a share therein, transmitted in
- Передача; привод; коробка передач; трансмиссия; прохождение; распространение ~ of loads передача нагрузок
- The transport of high voltage electricity. this is achieved with a transmission network (or grid). generally the network will connect large generators to lower voltage distribution networks where it will be transported to the majority of electricity consumers. alternatively, large scale electricity users may connect directly to the transmission network. management of transmission is a natural monopoly due to the economies of scale inherent to it. transmission system operator (tso) (also transmission network operator-
- The sending of information over a communications line or a circuit.
- The transportation of electric energy in bulk from a source or sources of supply to other systems or parts of a single system.
- Transfer of pathogens from one host to another
