Lagrangian for Circuits with Higher-Order Elements [PDF]
Entropy, 2019 The necessary and sufficient conditions of the validity of Hamilton’s variational principle for circuits consisting of (α,β) elements from Chua’s periodical table are derived. It is shown that the principle holds if and only if all the circuit elements lie on the so-called Σ-diagonal with a constant sum of the indices α and β.

Extended and Generic Higher-Order Elements for MEMS Modeling
Sensors, 2022 State-dependent resistors, capacitors, and inductors are a common part of many smart engineering solutions, e.g., in MEMS (Micro-Electro-Mechanical Systems) sensors and actuators, Micro/NanoMachines, or biomimetic systems. These memory elements are today

Mutual Transformation of Flux-Controlled and Charge-Controlled Memristors
IEEE Access, 2022 Two-ports for mutual transformation between flux-controlled memristors and charge-controlled memristors are proposed. Attention is paid to memristors with the region of negative differential memristance in the charge-flux constitutive relation, when such

A higher‐order equilibrium finite element method [PDF]
International Journal for Numerical Methods in Engineering, 2018 SummaryIn this paper, a mixed spectral element formulation is presented for planar, linear elasticity. The degrees of freedom for the stress are integrated traction components, ie, surface force components. As a result, the tractions between elements are continuous.

A higher‐order Trace finite element method for shells [PDF]
International Journal for Numerical Methods in Engineering, 2020 A higher-order fictitious domain method (FDM) for Reissner-Mindlin shells is proposed which uses a three-dimensional background mesh for the discretization. The midsurface of the shell is immersed into the higher-order background mesh and the geometry is implied by level-set functions.

A dynamical core based on a discontinuous Galerkin method for higher-order finite-element sea ice modeling [PDF]
Geoscientific Model Development, 2023 The ability of numerical sea ice models to reproduce localized deformation features associated with fracture processes is key for an accurate representation of the ice dynamics and of dynamically coupled physical processes in the Arctic and Antarctic ...

Higher-Order Hamiltonian for Circuits with (α,β) Elements
Entropy, 2020 The paper studies the construction of the Hamiltonian for circuits built from the (α,β) elements of Chua’s periodic table. It starts from the Lagrange function, whose existence is limited to Σ-circuits, i.e., circuits built exclusively from elements ...

Higher-order finite element approximation of the dynamic Laplacian [PDF]
ESAIM: Mathematical Modelling and Numerical Analysis, 2020 The dynamic Laplace operator arises from extending problems of isoperimetry from fixed manifolds to manifolds evolved by general nonlinear dynamics. Eigenfunctions of this operator are used to identify and track finite-time coherent sets, which physically manifest in fluid flows as jets, vortices, and more complicated structures.
