Figure 2. Schematic representation of (a) mixture of LC molecules with a polymer resulting in  agglomeration of the former with limited interaction between the mesogens and the polymer chains,  and (b) side-chain liquid crystalline polymer with the mesogen
Figure 4. Optical photomicrographs of films of polymer dispersed liquid crystals of 4’-octyl-4- 4’-octyl-4-biphenyl-carbonitrile (8CB) in poly(acry1ic acid) (PAA) with a molar ratio = 0.7/0.3, measured at  room temperature under mechanical stress at differ
Figure  9.  Schematic  illustration  of  the  two  methods  generally  used  to  obtain  photoinduced  orientation of azobenzene in polymers: (a) linearly polarized visible light on trans azobenzene, and  (b) linearly polarized visible light on the cis-ric
Figure 10. Three types of molecular reorientation of photoreactive SCLCPs irradiated with linearly  polarized  light:  (a)  no  photoreorientation,  (b)  selective  photoreorientation  of  photoreactive  mesogens; and (c) cooperative photoreorientation (74

Lately, models coupling phase-transformation and plasticity have been proposed in an effort to describe permanent inelasticy effects which are experimentally observed in SMAs [2,

But, as in the existence theorem (Theorem 3.1), we will obtain convergence of subsequences to solutions of the full problem. The approach here follows the abstract Γ-convergence

A bio-inspired tail was developed at the Center of Advanced Systems and Technologies (CAST), University of Tehran (Figs. The tail is actuated by three SMA wires and two strain

Using a kinetic Monte-Carlo approach, the energy- based model estimates the stochastic average in terms of volume fraction for a phase or phase variant deriving from the Gibbs

The idea of marking menus is that by using frequently the menus in novice state, the physical movement to choose a command can be associated to the command’s gesture, so that

In particular, we construct an asymptotic two-soliton solution of ( 1.1 ) that exhibits the following two regimes: (i) a transient turbulent regime characterized by a dra- matic
