The Concept of the Mixing Index

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract Many current measures of mixing, such as the statistics of concentration, the scalar dissipation rate, or dilution index, are based on the dilution of a single component or pseudo‐component. Because of this, they miss the influence of numerous conditions that directly change true mixing, such as initial separation of chemically distinct water ...

Stability Analisys of SEIR Epidemiological Models with Nonlinear Incidence:Case Study in the Central Java Province, Indonesia [PDF]

, 2011
SEIR epidemic models that are described as the system of ordinary differential equations with nonlinear incidence rates are proposed. In the SEIR model, the total population is divided into four classes, i.e., susceptible, exposed, infective, and ...

Construction of Lyapunov-Krasovskii functional for time-varying delay systems

, 2008
International audienceThis paper provides some new techniques to construct a Lyapunov-Krasovskii functional for time varying delay systems. The construction is based on a partitioning scheme of the time-varying delay leading to a new type of Lyapunov ...

Guaranteed H∞ Performance of Switched Systems with State Delays: A Novel Low-Conservative Constrained Model Predictive Control Strategy

Mathematics
In this paper, for the first time, a simultaneous design of a model predictive control plan and persistent dwell-time switching signal utilizing the conventional multiple Lyapunov–Krasovskii functional is proposed for linear delayed switched systems that

Nash Equilibrium and Robust Stability in Dynamic Games: A Small-Gain Perspective [PDF]

This paper develops a novel methodology to study robust stability properties of Nash equilibrium points in dynamic games. Small-gain techniques in modern mathematical control theory are used for the first time to derive conditions guaranteeing uniqueness

Improved results on stability analysis for a networked control system with two additive input delays

四川大学学报. 自然科学版, 2018
Stability analysis for a networked control system with two additive input delays is considered.By spitting the whole delay interval into three subintervals, a new LyapunovKrasovskii functional is constructed, which can make full use of the information ...
