Manufacturing Continuous Fiber‐Reinforced Printing Filaments: Development of a Post‐Consolidation Unit

Advanced Engineering Materials, EarlyView.
A novel, temperature‐controlled post‐consolidation unit is developed to test its potential to improve the melt impregnation process used to manufacture continuous fiber‐reinforced filaments for additive manufacturing of high‐performance thermoplastics.

Numerical Study of an Initial-Boundary Value Neumann Problem for a Singularly Perturbed Parabolic Equation

Моделирование и анализ информационных систем, 2016
For a singularly perturbed one-dimensional parabolic equation with a perturbation parameter ε multiplying the highest-order derivative in the equation, ε ∈ (0,1], an initial-boundary value Neumann problem is considered on a segment. In this problem, when

A parameter uniform essentially first order convergent numerical method for a parabolic singularly perturbed differential equation of reaction-diffusion type with initial and Robin boundary conditions

, 2019
In this paper, a class of linear parabolic singularly perturbed second order differential equations of reaction-diffusion type with initial and Robin boundary conditions is considered. The solution u of this equation is smooth, whereas the first derivative in the space variable exhibits parabolic boundary layers.

Convergence of an inverse problem for discrete wave equations [PDF]

, 2013
International audienceIt is by now well-known that one can recover a potential in the wave equation from the knowledge of the initial waves, the boundary data and the flux on a part of the boundary satisfying the Gamma-conditions of J.-L. Lions.

A time-splitting spectral scheme for the Maxwell-Dirac system

, 2005
We present a time-splitting spectral scheme for the Maxwell-Dirac system and similar time-splitting methods for the corresponding asymptotic problems in the semi-classical and the non-relativistic regimes.

3D (Bio) Printing Combined Fiber Fabrication Methods for Tissue Engineering Applications: Possibilities and Limitations

Advanced Functional Materials, EarlyView.
Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...

Efficient numerical schemes on modified graded mesh for singularly perturbed parabolic convection-diffusion problems [PDF]

Iranian Journal of Numerical Analysis and Optimization
In this study, numerical approaches to the singularly perturbed problems of convection diffusion type are presented. The backward Euler method is applied to a uniform mesh in the temporal domain, while in the spatial domain, we utilize both the hybrid ...

Parameter uniform essentially first order convergence of a fitted mesh method for a class of parabolic singularly perturbed Robin problem for a system of reaction-diffusion equations

, 2019
In this paper, a class of linear parabolic systems of singularly perturbed second order differential equations of reaction-diffusion type with initial and Robin boundary conditions is considered. The components of the solution $\vec u$ of this system exhibit parabolic boundary layers with sublayers.
