The stability test of radiometer

2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017
Either soil moisture or ocean salinity plays important role in globe water cycle. They are key parameters for monitoring the globe climate change [1]. Aperture Synthesis Microwave Imaging Radiometer will measure global sea surface salinity with 50-km spatial resolution, and the average monthly salinity accuracy aims at 0.1 psu (parts per thousand ...

Spectral Test for the Exponential Stability

Differential Equations, 2021
Consider the \(n\)-th order differential equation \[ A_{0}X^{(n)} +A_{1}X^{(n-1)}+\dots+A_{n-1}\dot{X}+A_{n}X=0, \tag{1} \] where \(A_{0},A_{1},\dots,A_{n}\) are constant \(m\times m\) matrices, the matrix \(A_{0}\) is nonsingular and \(X^{(k)}= \frac{d^{k}X}{dt^{k}}\), \(0 \leq k \leq n\). Let \(S(A)\) denote the spectrum of a matrix \(A\).

Fundamentals of stability testing

International Journal of Cosmetic Science, 1985
SynopsisThe principles on which stability tests are based are reviewed. The need to differentiate between product stability and product‐container compatibility is emphasized. Recognition of this distinction is fundamental to the efficient organisation and execution of stability tests.Attention is also drawn to the desirability of having for every ...

Spectral Test for Exponential Stability

Mathematical Notes, 2023
In this paper, the authors first consider an nth-order linear differential equation with constant coefficients in the complex Banach algebra B. Next, they also consider a linear system of ordinary differential equations with constant coefficients. Using the theory of commutative Banach algebras, an estimate of the solution with regard to the nth-order ...

Arithmetic tests forA-stability,A[α]-stability, and stiff-stability

BIT, 1978
Arithmetic tests forA-stability,A[α]-stability, and stiff-stability are presented as special cases of a general stability test for numerical integration methods. The test evolves from extracted properties of the characteristic polynomial (in two variables) of the numerical method applied to the prototype scalar ordinary differential equation

Testing for the stability of automatic stabilizers

Applied Stochastic Models and Data Analysis, 1989
AbstractThis paper examines the question of the stability of automatic stabilizers in the United States. Using a test suggested by Brown, Durbin and Evans, the analysis suggests that the magnitude of automatic stabilization of economic activity afforded by personal tax receipts has remained virtually invariant over the period 1939–1985.
