(2). The principle of the method is to replace Eq. (2) with a linear differential equation with an explicit time-dependent to have the form of the standard linear Mathieu equation: (3)y¨+(ω02−2qcosΩt)y=0, where ω02is the Duffing's frequency [18,19,37]. El-Dib ...

used for sets, limits, matrices, functions, and each knowledge range is also different. So if you use it for a long time or frequently, it is strongly recommended to create a suitable input symbol keyboard for yourself, which is more efficient and saves more time than a universal keyboard....
algebraic rainfall-runoff model proposed by the SCS (USDA-SCS, 1972), is widely used to estimate the fraction of rainfall not retained in the soil (e.g., AnnGNPS). The simplicity of this formula encourages the use of CN method, though it can only be applied on a minimum daily time ...

3.2 Time-domain methods A method is said to be a time-domain method if the data considered during the identification process take the form of time series (e.g., force and acceleration). Such techniques have the advantage that the signals are directly provided by current measurement devices; ...
The Schrödinger equation enables one to find the de Broglie wave associated with a particle and thus provides a basic tool for understanding microscopic phenomena.
