Abstract Objective COVID-19 data released by public health authorities is subject to inherent time delays. Such delays have many causes, including in reporting and the natural incubation period of disease. We develop introduce a numerical procedure recover distribution these from data. Methods extend previously-introduced compartmental model with nonlinear, distributed-delay term general distri...

Abstract A swarming model is a that describes the behavior of social aggregation large group animals or community humans. In this work, includes short-range repulsion and long-range attraction with presence time delay investigated. Moreover, convergence to consensus representing dispersion cohesion properties proved by using Lyapunov functional approach. Finally, numerical results are provided ...

This paper is pertained with the problem of admissibility analysis of uncertain discrete-time nonlinear singular systems by adopting the state-space Takagi-Sugeno fuzzy model with time-delays and norm-bounded parameter uncertainties. Lyapunov Krasovskii functionals are constructed to obtain delay-dependent stability condition in terms of linear matrix inequalities, which is dependent on the low...

This paper proposes to utilize intentional time delays as part of controllers improve the damping electromechanical oscillations power systems. Through stability theory, control parameter settings for which these in Power System Stabilizers (PSSs) small signal a system are systematically identified, including key regions plane remain connected effective operation. The shows that PSSs with two c...
