Small Parameters in Interactions

1991
Let S be a complete separable metric space and μa probability measure on S p that is the product of probability measures v t on S (in general, different for distinct t write 〈·〉0 = 〈·〉μ.

Small Parameter Methods: Basic Ideas

2014
We introduce basic ideas of asymptotic analysis and present a number of models which describe complex processes, the components of which occur at significantly different rates. Such models in a natural way contain a small parameter which is the ratio of the slow and the fast rates, thus lending themselves to asymptotic analysis.

Small-signal parameters for transistors

Electrical Engineering, 1954
The commonly used sets of parameters are discussed briefly and it is shown how the performance of the transistor can be determined with equal facility from any of the sets that may be provided.

Equivalent-Small-Parameters Method (ESPM)

2018
The principle of harmonic balance [1] is a basic principle that is universally applicable in nonlinear systems. The singular perturbation method is a commonly used approximation method for analyzing nonlinear systems. However, the perturbation method has long-term items in the process of solving nonlinear systems, that is, items that grow indefinitely ...

Small signal parameter of LLC converter

2017 IEEE 12th International Conference on Power Electronics and Drive Systems (PEDS), 2017
This paper presents the influence of circuit parameters on the small signal characteristics of the control to output transfer function of the LLC current resonant converter. The equivalent source model is employed for the analysis. To derive the dc gain and the internal resistance, circuit simulator is used.

Small parasitic parameters and chemical oscillations

Faraday Symposia of the Chemical Society, 1974
In treating chemical oscillators, it is common practice to use no more than two concentrations as dependent variables due to the mathematical difficulties with more than two. Other variables, necessarily involved to make the system nontrivial—the “pool” chemicals—are treated as parameters which are independent of time.

Parameters of photomultipliers with small photocathodes

Journal of Applied Spectroscopy, 1967
A description is given of FEU-64 tubes, cathode area 0.2 cm2, for Sb-Cs and multialkali cathodes. The latter can measure fluxes of 2 × 10−15 W in the range 4000–6000 a with a signal-to-noise ratio of 10 in a passband of 1 Hz.

Reflection Function and the Small Parameter Method

Differential Equations, 2004
The paper deals with periodic solutions of multi-dimensional differential systems. By combining symmetry properties expressed by the notion of reflection function with the small parameter method, sufficient conditions for the existence of periodic solutions are derived.
