The Space–Time Kernel-Based Numerical Method for Burgers’ Equations
It is well known that major error occur in the time integration instead of the spatial approximation. In this work, anisotropic kernels are used for temporal as well as spatial approximation to construct a numerical scheme for solving nonlinear Burgers ...

Flows of singular vector fields and applications to fluid and kinetic equations [PDF]
Several physical phenomena arising in fluid dynamics and kinetic equations can be modeled by nonlinear transport PDE. Such quantities are the vorticity of a fluid, or the density of a collection of particles advected by a velocity field which is highly ...

This study examines how helicoidal architectures with different porosities respond to bending. Adjusting layer angle and spacing in 3D‐printed polymers reveals clear tradeoffs between stiffness, strength, and energy absorption. Experiments and simulations highlight designs that distribute stress effectively, offering pathways for optimizing lightweight

Semilinear anisotropic evolution partial differential equations
Consider the anisotropic Cauchy problem \(\partial_t u+P(D)u-G(\partial^\alpha u)=0\) for \(t>0\), \(u(x,0)=u_0(x)\), where \(P(D)=\sum_{| \alpha:\rho| \leq m} c_\alpha D_x^\alpha\) is a quasi-elliptic operator of (anisotropic) order \(m\) and \(G\) is a homogeneous polynomial with constant coefficients.

Comparison of Triply Periodic Minimal Surface Energy Absorbers Under Uniaxial Compressive Loading
This study investigates LCD 3D printed Triply Periodic Minimal Surface (TPMS) structures as mechanical energy absorbers. By comparing various base designs and layered combinations under uniaxial compression, it identifies that a Diamond‐Gyroid sandwich structure offers superior performance.

On Entropy Solutions of Anisotropic Elliptic Equations with Variable Nonlinearity Indices
For a certain class of second-order anisotropic elliptic equations with variable nonlinearity indices and L1 right-hand side we consider the Dirichlet problem in arbitrary unbounded domains.

Discontinuous Galerkin Methods on hp-Anisotropic Meshes I: A Priori Error Analysis [PDF]
We consider the a priori error analysis of hp-version interior penalty discontinuous Galerkin methods for second-order partial differential equations with nonnegative characteristic form under weak assumptions on the mesh design and the local finite ...
