Shape Fixity and Shape Recovery of Polyurethane-Shape Memory Polymer Foam.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 2002 The thermomechanical properties of polyurethane shape memory polymer (SMP) foams were investigated experimentally. The results obtained can be summarized as follows. (1) By cooling the foam after compressive deformation at high temperature, stress decreases and the deformed shape is fixed. Stress decreases markedly in the region of

Shape recovery for sparse‐data tomography [PDF]
Mathematical Methods in the Applied Sciences, 2017 A two‐dimensional sparse‐data tomographic problem is studied. The target is assumed to be a homogeneous object bounded by a smooth curve. A nonuniform rational basis splines (NURBS) curve is used as a computational representation of the boundary. This approach conveniently provides the result in a format readily compatible with computer‐aided design ...

High performance shape memory polyurethane synthesized with high molecular weight polyol as the soft segment [PDF]
, 2012 Shape memory polyurethanes (SMPUs) are typically synthesized using polyols of low molecular weight (MW~2,000 g/mol) as it is believed that the high density of cross-links in these low molecular weight polyols are essential for high mechanical strength ...

Simultaneous photometric invariance and shape recovery [PDF]
2009 IEEE 12th International Conference on Computer Vision, 2009 In this paper, we identify the constraints under which the generally ill-posed problem of simultaneous recovery of surface shape and its photometric invariants can be rendered tractable. We examine the cases where a single or more images are acquired using different lighting directions with known illuminant power.

A Methodology for Multi-Camera Surface-Shape Estimation of Deformable Unknown Objects
Robotics, 2018 A novel methodology is proposed herein to estimate the three-dimensional (3D) surface shape of unknown, markerless deforming objects through a modular multi-camera vision system.

Microstructural evaluation on shape recovery in stainless Fe-Mn-Si-Cr-Ni-Co SMA processed by wire drawing [PDF]
Materials Research, 2014 The effect of the microstructure on the shape recovery in stainless Fe-8Mn-5Si-13Cr-6Ni-12Co shape memory steel (SSMS) was evaluated using tensile tests and reversion temperature of 600ºC for a pre-strain of 4%.

Biosurface and Biotribology, 2019 The surface topography has a great effect on the behaviour of adherent cells. We report an efficient method to prepare shape memory surfaces with dynamically changed micropatterns, which can be induced by near-infrared (NIR) light by varying the power ...

Recovery-informed Theory: Situating the Subjective in the Science of Substance Use Disorder Recovery [PDF]
, 2019 As recovery from substance use disorder becomes more than a mere quantifiable outcome, there exists a need to discuss and propose the underlying theoretical constructs that ultimately describe and identify the science of recovery.
