Electrothermal Compact Drift Model of TiO Memristors: Verilog-A Implementation and Dimensionless Regime Mapping
N. G. Koudafokê, Hilda A. Cerdeira, L. A. Hinvi +1
Compact models of titanium-dioxide memristors used in circuit simulation commonly follow the drift formulation of Strukov \textit{et al.} and assume a constant ionic mobility, alth…
Current-Gated Nonlinear Dynamics of a Self-Heating Memristor: an Electrothermal Extension of the Pickett Filamentary Model
N. G. Koudafokê, Florian Günther, Hilda A. Cerdeira +1
Self-heating couples the electrical and thermal states of filamentary memristors. However, the widely used Pickett compact model of resistive switching is isothermal and th…
Thermal Control of Hysteresis and Deterministic Chaos in a Memristive MEMS Resonator
N. G. Koudafokê, Thierry Njougouo, Hilda A. Cerdeira +1
We investigate the nonlinear dynamics of a thermo-electro-mechanically coupled memristive resonator comprising a doubly clamped Euler--Bernoulli microbeam, an RLC circuit, and a Ti…
Chimera state in a neuronal network under the action of a magnetic field
Gael R Simo, Carmel T lambu, Adamou Dang Koko +3
The Hindmarsh-Rose (HR) neuronal network has recently been the subject of studies highlighting the influence of the electric field on the chimera states within it. In this study, w…
Characterization of Chaotic and Homogeneous coexisting dynamics of a Memristive Thermo-Controlled MEMS
N. G. Koudafokê, Thierry Njougouo, Hilda A. Cerdeira +1
This work presents the mathematical modeling and numerical investigation of a thermo-controlled Micro-Electro-Mechanical System (MEMS) obtained by coupling an HP memristor with mec…
Topological transitions in swarmalators systems
Patrick Louodop, Michael N. Jipdi, Gael R. Simo +6
After its development, the swarmalators model attracted a great deal of attention since it was found to be very suitable to reproduce several behaviors in collective dynamics. Howe…
Mobile oscillators in a mobile multi-cluster network
Venceslas Nguefoue Meli, Thierry Njougouo, Steve J. Kongni +3
Different collective behaviors emerging from the unknown have been examined in networks of mobile agents in recent years. Mobile systems, far from being limited to modeling and stu…
Attractive-repulsive challenge in swarmalators with time-dependent speed
Steve J. Kongni, Thierry Njougouo, Gaël R. Simo +3
We examine a network of entities whose internal and external dynamics are intricately coupled, modeled through the concept of ``swarmalators'' as introduced by O'Keeffe et al. \tex…
Expected and unexpected routes to synchronization in a system of swarmalators
Steve J. Kongni, Thierry Njougouo, Patrick Louodop +3
Systems of oscillators whose internal phases and spatial dynamics are coupled, swarmalators, present diverse collective behaviors which in some cases lead to explosive synchronizat…
