Collocation Methods for Optimization in a Modelica Environment [PDF]
The solution of generic dynamic optimization problems described by Modelica, and its extension Optimica, code using direct collocation methods is discussed. We start by providing a description of dynamic optimization problems in general and how to solve them by means of direct collocation.

Approximations to linear Klein–Gordon Equations using Haar wavelet
In this research article, two Haar wavelet collocation methods (HWCMs) (namely one dimensional HWCM and two dimensional HWCM) are adapted to approximate linear homogeneous and linear non-homogeneous Klein–Gordon equations.

New recursive approximations for variable-order fractional operators with applications
To broaden the range of applicability of variable-order fractional differential models, reliable numerical approaches are needed to solve the model equation.In this paper, we develop Laguerre spectral collocation methods for solving variable-order ...

Surprisingly, a cell can bind to itself to make a self‐adhesion, which engineered here to improve how cells attach to biomaterials. Nanoprinting are used to make 3D structures smaller than cells–called Self‐Adhesion‐Tunnels (SATs)–around which cells can wrap and bind to themselves.

Laser structuring of biocompatible polymers creates precise surface patterns that influence cell organization. By imaging, contact angle measurements, and chemical analysis, this study demonstrates the ability of laser‐induced micro‐structured surfaces to guide muscle cell alignment. These findings support laser patterning of biopolymers as a promising

This review focuses on the application of synthetic biodegradable microarray patches (MAPs) in sustained drug delivery. Compared to conventional MAPs which release drugs into the skin in an immediate manner, these implantable MAPs release drugs into skin microcirculation gradually as the biodegradable polymers degrade, thus offering sustained release ...

LEBESGUE CONSTANTS ARISING IN A CLASS OF COLLOCATION METHODS [PDF]
Estimates are obtained for the Lebesgue constants associated with the Gauss quadra- ture points on (i1, +1) augmented by the point i1 and with the Radau quadrature points on either (i1, +1) or (i1, +1). It is shown that the Lebesgue constants are O( p N),

This study employs a CFD model to simulate laser cutting of copper current collectors used for Li‐Ion battery production. This model predicts cut edge quality by assessing the influence of power, scanner speed, and foil thickness. Defects are classified and an optimal working area is found.

Convergence of a collocation scheme for a retarded potential integral equation [PDF]
Time domain boundary integral formulations of transient scattering problems involve retarded potential integral equations (RPIEs). Solving such equations numerically is both complicated and computationally intensive, and numerical methods often prove to ...
