...Lan Xu; Xueyi Zhu Purpose Currently, China’s manufacturing industry chain still faces the danger of chain breakage due to the persistent “lack of technology” issue. The definition and detection of key nodes in the industry chain are significant to the enhancement of the stability of the industry...

... plants are considered. A method of the stability analysis for a system with uncertain parameters is described. Simple examples illustrate the presented approaches. Let us consider a static plant with input vector u∈U and output vector y∈Y, described by a function...

... methodology, based on methods of Lyapunov theory, Perturbations theory [Asymptotic method in theory of non‐linear oscillations (1963)] in accordance with Stability postulate and Singularity postulate is developed. This asymptotic approach (called – LPSS approach...

...Soucheng OuYang; Yi Lin While still arguing whether a quasi‐linear equation has a “stability” problem in integration, comparative analyses are made by numerical experimentations using conservation with smoothing and non‐conservation schemes as well as a time‐moving treatment scheme proposed...
