The stability of Cohen–Grossberg neural networks with time dependent delays

open access: yesИзвестия высших учебных заведений. Поволжский регион: Физико-математические науки, 2023
Background. The study is devoted to the analysis of stability in the sense Lyapunov Cohen-Grossberg neural networks with time-dependent delays. To do this, we study the stability of the steady-state solutions of systems of linear differential equations ...

Implementation and Adoption Delays in Market Share Models Under Feedback Advertising Policies

open access: yesIEEE Access, 2021
This paper proposes definitions of implementation and adoption delays, arising from firm and client behaviors, in the context of market share dynamics. Information delay refers to the existence of lags in the information used for the advertising policy ...

EFFECT OF A VARIABLE DELAY IN DELAYED DYNAMICAL SYSTEMS [PDF]

open access: yesInternational Journal of Bifurcation and Chaos, 2001
We report numerical evidence of the effects of a periodic modulation in the delay time of a delayed dynamical system. By referring to a Mackey–Glass equation and by adding a modulation in the delay time, we describe how the solution of the system passes from being chaotic to shadow periodic states.

Method for Designing Robust and Energy Efficient Railway Schedules

open access: yesEnergies, 2021
The robustness of the timetable is a sensitive issue in the daily realization of railway operations. As shown in the paper, robustness is a function of time reserves that helps to prevent unscheduled stops resulting from traffic disruptions and causing a

Wait Times and Survival in Lung Cancer Patients across the Province of Quebec, Canada

open access: yesCurrent Oncology, 2022
Lung cancer is the leading cause of cancer death worldwide, with a five-year survival of 22% in Canada. Guidelines recommend rapid evaluation of patients with suspected lung cancer, but the impact on survival remains unclear.

A Review on Significant Factors Causing Delays in Saudi Arabia Construction Projects

open access: yesSmart Cities, 2022
The Kingdom of Saudi Arabia (KSA) is suffering major delays in construction projects. Because the construction business in Saudi Arabia has changed dramatically over the last three decades, it is crucial to conduct a thorough study into the reasons for ...

Predictors and pathway of maternal near miss: A case–control study in a tertiary care facility in Kolkata

open access: yesIndian Journal of Community Medicine, 2022
Background: Use of maternal near-miss (MNM) cases as an adjunct has been advocated to understand the processes of obstetric care because they share similar pathways as maternal deaths. Identifying the predictors and care pathway is crucial to improve the

Bifurcation analysis for a delayed SEIR epidemic model with saturated incidence and saturated treatment function

open access: yesJournal of Biological Dynamics, 2019
A delayed SEIR epidemic model with saturated incidence and saturated treatment function is considered in this paper. Sufficient conditions for the existence of local Hopf bifurcation are established by regarding the possible combination of the two delays
