Slowly varying system
WebbIn the decade following documented volcanic activity on the East Pacific Rise near 9°50′N, we monitored hydrothermal vent fluid temperature variations in conjunction with approximately yearly vent fluid sampling to better understand the processes and physical conditions that govern the evolution of seafloor hydrothermal systems. The temperature … In real analysis, a branch of mathematics, a slowly varying function is a function of a real variable whose behaviour at infinity is in some sense similar to the behaviour of a function converging at infinity. Similarly, a regularly varying function is a function of a real variable whose behaviour at infinity is similar to the behaviour of a power law function (like a polynomial) near infinity. These classes of functions were both introduced by Jovan Karamata, and have found several importan…

WebbThe predictive approach can be very useful in analyzing systems on which measurements can not be done more frequently. The systems for which the prediction can be applied are called slowly-varying systems [5], i.e. systems whose matrices change slowly with time. chinese delivery watertown maWebbDifferences in Tween 80 concentration, varying from 0.5 to 2.0%, did not change the release kinetics to a large extent.
