Inductive inference of ultimately periodic sequences
BIT, 1988An algorithm is presented for inductive inference of ultimately periodic sequences. It can be implemented in linear time and space.

An induction period in the pyrolysis of acetylene
Physical Chemistry Chemical Physics, 2001Acetylene was pyrolysed in a flow system between 854 and 970 K, at pressures between 27 and 127 Torr and at residence times between 8 and 1520 ms. Both vinylacetylene and benzene were observed to be primary products, but secondary processes removed vinylacetylene and formed benzene.

The induction of periodic and chaotic activity in a molluscan neurone
Biological Cybernetics, 1982During prolonged exposure to extracellular 4-aminopyridine (4 AP) the periodic activity of the somatic membrane of an identified molluscan neurone passes from a repetitive regular discharge of greater than 90 mV amplitude action potentials, through double discharges to less than 50 mV amplitude oscillations.

Kinetics of the induction of DNA synthesis in lymphocytes by periodate
Experimental Cell Research, 1976Abstract Treatment of lymphocytes with NaIO4 introduces aldehyde moieties on surface sialyl residues and induces extensive blastogenesis. Cysteine, a compound which reacts with aldehydes through its amino and thiol groups to form a thiazolidine derivative, was found to inhibit transformation of NaIO4-treated mouse lymphocytes.

Dark-Period Induction of Zygospores in Mucor
Mycologia, 1987This study was conducted to test the hypothesis that the factor responsible for erratic mating behavior among certain Mucor species is a requirement for an induction period of darkness. Zygospores are formed with continuous natural or artificial light after a dark period.

Theory of long induction periods
Journal of Crystal Growth, 1987Abstract Current theories relating induction periods in crystallization to either stationary nucleation rate or relaxation time of embryo distribution are of limited validity. The Zeldovich-Frenkel theory overestimates the growth rate of postcritical embryos with high surface energy.

Video luminescent barometry - The induction period
31st Aerospace Sciences Meeting, 1993Video monitoring of oxygen quenching of the photoluminescence of platinum octaethylporphyrin (PtOEP) in silicone polymer resin may be used to measure pressure distribution over an airfoil. A continuous increase of the luminescence intensity of PtOEP on exposure to the exciting light is known as the induction effect.

The Induction Period in Chain Reactions
The Journal of Chemical Physics, 1952The conditions for the establishment of a stationary state in a system of consecutive reactions can be investigated quantitatively in a sufficient number of cases to permit precise criteria to be formulated generally for the length of the induction period (i.e., prestationary state period) in chain reactions.

The Induction Period and the Charge on the Developer Ion
The Journal of Photographic Science, 1975AbstractThe initial stages of the process of chemical development are studied. Expressions for thesilver ion flux flowing toward the surface of a growing silver speck are derived for two extreme cases – when the ion current is restricted by Ohmic resistance of the silver bromide grain and when it is determined by the diffusion of the silver ion ...
