Two-Way Shape Memory Effect Driven Solar Sails for Active Solar Radiation Pressure Modulation

Aerospace
Solar sailing has proven to be an effective solution for cost-effective and long-term space missions due to its fuel-free propulsion. While multiple large-scale solar sails based on kilogram-class satellites have been developed and tested in space, solar

Shape-memory behavior of cross-linked semi-crystalline polymers and their blends

eXPRESS Polymer Letters, 2015
The present study deals with thermally induced one-way and invertible two-way shape-memory effect (SME) in covalent networks on the basis of crystallizable (co)polymers and their blends and is an attempt to generalize the results of own investigation ...

TRAINING AND THE TWO WAY MEMORY EFFECT IN COPPER BASED SHAPE MEMORY ALLOYS [PDF]

Le Journal de Physique IV, 1991
Experimental results giving information about the mechanisms of the two way memory effect are presented. It is shown that local martensite stabilization and true plastic deformations have to be considered as undesirable side-effects of training.

Role of Nickel Content in One-Way and Two-Way Shape Recovery in Binary Ti-Ni Alloys

Metals, 2021
The shape recovery characteristics of titanium nickelide with an Ni content of 50.0 at % and 50.7 at % were studied in a wide range of structures obtained as a result of cold drawing with an accumulated true strain of e = 0.52 and subsequent annealing in

Homogenization in magnetic-shape-memory polymer composites

, 2017
Magnetic-shape-memory materials (e.g. specific NiMnGa alloys) react with a large change of shape to the presence of an external magnetic field. As an alternative for the difficult to manifacture single crystal of these alloys we study composite materials

Fractional-Order Traveling Wave Approximations for a Fractional-Order Neural Field Model

Frontiers in Computational Neuroscience, 2022
In this work, we establish a fractional-order neural field mathematical model with Caputo's fractional derivative temporal order α considering 0 < α < 2, to analyze the effect of fractional-order on cortical wave features observed preceding seizure

Languages adapt to their contextual niche [PDF]

, 2014
It is well established that context plays a fundamental role in how we learn and use language. Here we explore how context links short-term language use with the long-term emergence of different types of language system.

Heap Abstractions for Static Analysis [PDF]

, 2015
Heap data is potentially unbounded and seemingly arbitrary. As a consequence, unlike stack and static memory, heap memory cannot be abstracted directly in terms of a fixed set of source variable names appearing in the program being analysed.

Martensitic Tweed and the Two-Way Shape-Memory Effect

, 1997
We briefly introduce tweed, which is found above the martensitic transition in a variety of shape-memory, high-T_c, and other materials. Based on our previous mapping of the problem onto a spin-glass model, we conjecture that the two-way shape-memory effect is due to tweed.
