Nonlinear phenomena in a high–power heating unit with pulse modulated control
MATEC Web of Conferences, 2017 In this paper we describe the transitions from regular periodic mode to quasiperiodicity that can be observed in a pulse–width modulated control system for a high–power heating unit.

Convergence of the Euler-Maruyama method for multidimensional SDEs with discontinuous drift and degenerate diffusion coefficient [PDF]
, 2018 We prove strong convergence of order $1/4-\epsilon$ for arbitrarily small $\epsilon>0$ of the Euler-Maruyama method for multidimensional stochastic differential equations (SDEs) with discontinuous drift and degenerate diffusion coefficient.

On the limit cycles of a class of discontinuous piecewise linear differential systems
Discrete & Continuous Dynamical Systems - B, 2020 In this paper we consider discontinuous piecewise linear differential systems whose discontinuity set is a straight line L which does not pass through the origin. These systems are formed by two linear differential systems of the form ̇x= Ax ± b. We study the limit cycles of this class of discontinuous piecewise linear differential systems.

Minimizers with discontinuous velocities for the electromagnetic variational method
, 2011 The electromagnetic two-body problem has \emph{neutral differential delay} equations of motion that, for generic boundary data, can have solutions with \emph{discontinuous} derivatives. If one wants to use these neutral differential delay equations with \

On the periodic solutions of discontinuous piecewise differential systems
, 2015 Motivated by problems coming from different areas of the applied science we study the periodic solutions of the following differential system $$x'(t)=F_0(t,x)+\varepsilon F_1(t,x)+\varepsilon^2 R(t,x,\varepsilon),$$ when $F_0$, $F_1$, and $R$ are discontinuous piecewise functions, and $\varepsilon$ is a small parameter. It is assumed that the manifold $

International Journal of Bifurcation and Chaos, 2023 In the past years the study of continuous or discontinuous piecewise differential systems has attracted significant interest, due to their wide use to model many natural phenomena. Important questions such as finding an upper bound for the number of limit cycles of such systems and their possible configurations have been considered by many authors ...

Dynamics at a switching intersection:hierarchy, isonomy, and multiple-sliding [PDF]
, 2014 If a set of ordinary differential equations is discontinuous along some thresh- old, solutions can be found that are continuous, if sometimes multi-valued.

Melnikov analysis in nonsmooth differential systems with nonlinear switching manifold
, 2018 We study the family of piecewise linear differential systems in the plane with two pieces separated by a cubic curve. Our main result is that 7 is a lower bound for the Hilbert number of this family.

Advanced Materials Technologies, EarlyView.Hierarchical multi‐material TPMS lattices are engineered as flexible tactile sensors by combining soft and stiff elastomeric layers with a conformal conductive coating. The bilayer architecture delivers sensitivity at low pressures while maintaining a broad detectable range under large loads, enabling reliable pressure and vibration monitoring for ...

Smoothing tautologies, hidden dynamics, and sigmoid asymptotics for piecewise smooth systems [PDF]
, 2015 Switches in real systems take many forms, such as impacts, electronic relays, mitosis, and the implementation of decisions or control strategies. To understand what is lost, and what can be retained, when we model a switch as an instantaneous event ...
