In this article, a periodic self-triggered impulsive (PSTI) control scheme is proposed to achieve synchronization of neural networks (NNs). Two kinds gains with constant and random values are considered, the corresponding criteria obtained based on tools from control, event-driven theory, stability analysis. The designed triggering protocol simpler, easier implement, more flexible compared some previously reported algorithms as combines advantages sampling control. addition, chaotic NNs via...

Hormesis, a phenomenon whereby exposure to high levels of stressors is inhibitory but low (mild, sublethal and subtoxic) doses are stimulatory, challenges decision-making in the management cancer, neurodegenerative diseases, nutrition ecotoxicology. In latter, increasing amounts pesticide may lead upsurges rather than declines pests, ecological paradoxes that difficult predict. Using novel re-formulation Ricker population equation, we show how interactions between intervention strengths dose...

Visual inspection of the workplace and timely reminders unsafe behaviors (e.g, not wearing a helmet) are particularly significant for avoiding injuries to workers on construction site. Video surveillance systems generate large amounts non-structure image data site this purpose; however, they require real-time recognition automation solutions based computer vision. Although various deep-learning-based models have recently provided new ideas identifying helmets in traffic monitoring, few...

In the realm of integrated pest management (IPM), intensity IPM should be dynamically adjusted over time according to pests in practical applications. To address this, we involve a dynamic regulatory factor into discrete model rather than switching system. Further, existence and local stability fixed points interesting bifurcation diagrams have been analysed provided. Numerical investigations validate theoretical results reveal diverse intricate dynamical behaviour proposed system, which can...

ABSTRACT A Filippov system of crop‐pest‐natural enemy with a Holling‐II type functional response function is developed based on the fear effect and threshold control strategy. The strategy mainly means controlling pests natural enemies. When number enemies below threshold, cannot achieve pest population needed to suppress outbreak. In this case, will affect pest's survival mode, thus affecting dynamic behavior. However, exceeds density, there no need system. At point, almost zero. behavior...

The switched discrete host-parasitoid model concerning integrated pest management (IPM) has been proposed in the present work, and economic threshold (ET) is chosen to guide switches. That is, if density of host (pest) population increases exceeds ET, then biological chemical tactics are applied together. Those multiple control measures suspended once falls below ET. Firstly, existence stability several types equilibria system have discussed briefly, two- or three-parameter bifurcation...

A novel periodically forced Filippov Holling II prey-predator model by applying threshold policy control (TPC) and integrated pest management (IPM) strategies is proposed, the periodic forcing described as a Fourier series with different terms. Our work aim to address how affects dynamic behaviors of proposed system reasonably realize control. Based on above considerations, relations between sliding region solution are analyzed. Then, existence conditions its global stability addressed....

Insects such as locusts and some moths can transform from a solitarious phase when they remain in loose populations gregarious phase, may swarm. Therefore, the key to effective management of outbreaks species desert locust Schistocercagregaria is early detection are threshold state between two phases, followed by timely control their hopper stages before fledge because flying adult swarms costly often ineffective. Definitions gregarization thresholds should assist preventive measures avoid...

The switched discrete host-parasitoid model with Beverton-Holt growth concerning integrated pest management has been proposed, and the switches are guided by economic threshold (ET). (IPM) tactics applied to prevent injury if density of host population exceeds ET, IPM called off once descends below ET. To begin with, regular virtual equilibria system discussed two or three parameter-bifurcation diagrams, which reveal regions different types equilibria. Besides, numerical bifurcation analyses...

<abstract><p>We investigated the phenomenon of pseudo-Hopf bifurcation in a Filippov Hindmarsh-Rose neuronal system with threshold switching, and existence crossing limit cycles was proved by constructing half-return mapping. Through control, firing state could be switched, allowing transitions from non-periodic to periodic state, as well evolution spiking bursting. Furthermore, through exhibited coexistence multiple attractors, stable states, or have sets that attract...

Dynamic signal control is complex but important to increase intersection capacity and decrease delays at the same time. A genetic fuzzy logic model for multi-phase isolated intersections developed in this study. This based on sufficient fusion of hierarchical algorithms with logic, which can ensure performance controller reduce structure as well. In paper, detailed formulation given required procedures coding membership function rules into chromosome are described. Validation effectiveness...

<abstract><p>A threshold strategy model is proposed to demonstrate the extinction of tumor load and mobilization immune cells. Using Filippov system theory, we consider global dynamics sliding bifurcation analysis. It was found that an effective cell targeted therapy captures more complex kinetics kinetic behavior changes as altered, including limit cycle some previously described bifurcations. The analysis showed abnormal in patients' cells could be detected time by using...

The switching discrete prey-predator model concerning integrated pest management has been proposed, and the switches are guided by economic threshold (ET). To begin with, regular virtual equilibria of system have discussed key parameter bifurcation diagrams for existence which reveal three different regions equilibria. Besides, numerical analyses show that may complicated dynamics behavior including chaos coexistence multiple attractors. Finally, effects parameters on frequencies times...

<abstract><p>In ecology, the impact of predators goes beyond killing prey, mere presence reduces ability prey to reproduce. In this study, we extend predator-prey model with fear effect by introducing state-dependent control a nonlinear action threshold depending on combination density and its changing rate. We initially defined Poincaré map proposed studied fundamental properties. Utilizing properties map, periodic solution is further investigated, including existence stability...
