Multi-attribute parametric optimisation of shape memory polymer properties for adaptive orthopaedic plasters [PDF]

, 2022
Fall-related injuries and road accidents often demand orthopaedic emergency care and management in hospitals. Early and effective fracture treatment immobilisation techniques are essential for stabilising the musculoskeletal system of the patient. During

Shape manipulation using physically based wire deformations [PDF]

, 2010
This paper develops an efficient, physically based shape manipulation technique. It defines a 3D model with profile curves, and uses spine curves generated from the profile curves to control the motion and global shape of 3D models.

A tension approach to controlling the shape of cubic spline surfaces on FVS triangulations [PDF]

, 2009
We propose a parametric tensioned version of the FVS macro-element to control the shape of the composite surface and remove artificial oscillations, bumps and other undesired behaviour.

Shape preserving properties of generalized Bernstein operators on Extended Chebyshev spaces [PDF]

Numerische Mathematik, 2009
We study the existence and shape preserving properties of a generalized Bernstein operator $B_{n}$ fixing a strictly positive function $f_{0}$, and a second function $f_{1}$ such that $f_{1}/f_{0}$ is strictly increasing, within the framework of extended Chebyshev spaces $U_{n}$. The first main result gives an inductive criterion for existence: suppose

Polynomial cubic splines with tension properties [PDF]

, 2010
In this paper we present a new class of spline functions with tension properties. These splines are composed by polynomial cubic pieces and therefore are conformal to the standard, NURBS based CAD/CAM ...

Thermal-Mechanical Properties of Polyurethane-Clay Shape Memory Polymer Nanocomposites [PDF]

, 2010
Shape memory nanocomposites of polyurethane (PU)-clay were fabricated by melt mixing of PU and nano-clay. Based on nano-indentation and microhardness tests, the strength of the nanocomposites increased dramatically as a function of clay content, which is

Effect of Thickness on the Shape Memory Properties of Bisphenol A Epoxy Based Shape Memory Polymer Composites [PDF]

, 2021
Shape memory polymer (SMP) is one of the most highly researched branches of polymer materials in the recent past. It is often called as a smart material due to its unique capability to memorize original shape.

Shape preserving properties of univariate Lototsky–Bernstein operators

Journal of Approximation Theory, 2017
The main goal of the present paper is to study shape preserving properties of univariate Lototsky-Bernstein operators, which are based on Lototsky-Bernstein basis functions. The Lototsky-Bernstein basis functions \(b_{n,k} (x)\) (\(0 \leq k\leq n\)) of order \(n\) are constructed by replacing \(x\) in the \(i\)th factor of the generating function for ...

Shape-Preservation of the Four-Point Ternary Interpolating Non-stationary Subdivision Scheme

Frontiers in Physics, 2020
In this paper, we present the shape-preserving properties of the four-point ternary non-stationary interpolating subdivision scheme (the four-point scheme). This scheme involves a tension parameter.
