Shape Recovery of Viscoelastic Deployable Structures [PDF]
51st AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics, and Materials Conference<BR> 18th AIAA/ASME/AHS Adaptive Structures Conference<BR> 12th, 2010 The paper investigates the shape recovery behavior of a simple beam and a tape spring made of LDPE under prescribed deformation history at room temperature. The linear viscoelastic material properties of LDPE were measured via creep tests. An analysis of a LDPE beam under four-point bending with an imposed history of vertical deflection and reaction ...

Synthesis and shape memory behavior of hyperbranched polyimides from thiol-ene click reaction
eXPRESS Polymer Letters, 2020 Shape memory polymers (SMPs) with novel functions have received increasing attention, but hyperbranched polyimide (HBPI)-based SMPs have rarely been reported. Herein, we have synthesized a series of thiol-ended hyperbranched polyimides (BTMP-n, n = 6, 9,

Recovery shape of physical activity after COVID-19 pandemic
Journal of Sport and Health Science, 2023 Background: Since the shutdowns associated with the coronavirus disease 2019 pandemic, there has been limited discourse on physical activity (PA) recovery (i.e., the ability of individuals to resume PA at pre-pandemic levels), including recovery rate ...

Convex Cardinal Shape Composition
, 2015 We propose a new shape-based modeling technique for applications in imaging problems. Given a collection of shape priors (a shape dictionary), we define our problem as choosing the right dictionary elements and geometrically composing them through basic ...

Non affine deformations and shape recovery in solids undergoing martensitic transformations
, 2008 We study, using molecular dynamics simulations, the kinetics of shape recovery in a model solid undergoing transformations from square to a general rhombic lattice, the triangular lattice being included as a special case.

Multiple sessions of transcranial direct current stimulation to the intact hemisphere improves visual function after unilateral ablation of visual cortex [PDF]
, 2013 Damage to cerebral systems is frequently followed by the emergence of compensatory mechanisms, which serve to reduce the effects of brain damage and allow recovery of function. Intrinsic recovery, however, is rarely complete.

Integrating qualitative and quantitative shape recovery [PDF]
International Journal of Computer Vision, 1994 Recent work in qualitative shape recovery and object recognition has focused on solving the “what is it” problem, while avoiding the “where is it” problem. In contrast, typical CAD-based recognition systems have focused on the “where is it” problem, while assuming they know what the object is. Although each approach addresses an important aspect of the
