Mathematics in Engineering, 2023 We prove the existence of a solution to a quasilinear system of degenerate equations, when the datum is in a Marcinkiewicz space. The main assumption asks the off-diagonal coefficients to have support in the union of a geometric progression of squares.

Two-grid virtual element discretization of quasilinear elliptic problem
Mathematical Modelling and AnalysisIn this paper a two grid algorithm for quasilinear elliptic problem based on virtual element method (VEM) discretization is proposed. With this new algorithm the solution of a quasilinear elliptic problem on a fine grid is reduced to the solution of a ...

A quasi-linear parabolic system of chemotaxis
Abstract and Applied Analysis, 2006 We consider a quasi-linear parabolic system with respect to unknown functions u and v on a bounded domain of n-dimensional Euclidean space. We assume that the diffusion coefficient of u is a positive smooth function A(u), and that the diffusion ...

Classical solutions to quasilinear parabolic problems with dynamic boundary conditions
, 2015 We study linear nonautonomous parabolic systems with dynamic boundary conditions. Next, we apply these results to show a theorem of local existence and uniqueness of a classical solution to a second order quasilinear system with nonlinear dynamic ...

Quasilinear systems with several periodic solutions [PDF]
Proceedings of the American Mathematical Society, 1971 By using topological degree, it is proved that for a certain class of quasilinear systems of ordinary differential equations of the form \[ x ˙ = A ( t ) x + ϵ μ f ( x , t , μ ) +

Advanced Robotics Research, EarlyView.Integrating proprioceptive capabilities in balloon‐type robots enhances safe human–machine interactions. Traditional pressure estimates are inadequate due to nonlinear relationships. Instead, embedding stretchable sensors effectively measures deformation. This design optimizes sensor geometry to minimize damage risks.

Spectral Approximation of an Oldroyd Liquid Draining down a Porous Vertical Surface
Discrete Dynamics in Nature and Society, 2011 Consideration is given to the free drainage of an Oldroyd four-constant liquid from a vertical porous surface. The governing systems of quasilinear partial differential equations are solved by the Fourier-Galerkin spectral method.

Disentangling Coincident Cell Events Using Deep Transfer Learning and Compressive Sensing
Advanced Intelligent Systems, EarlyView.Overlapping cells during detection distort single‐cell measurements and reduce diagnostic accuracy. A hybrid framework combining a fully convolutional neural network with compressive sensing to disentangle overlapping signals directly from raw time‐series data is presented.
