Some New Concepts of Shape Memory Effect of Polymers [PDF]

, 2014
In this study some new concepts regarding certain aspects related to shape memory polymers are presented. A blend of polylactic acid (PLA) (80%) and polybutylene succinate (PBS) (20%) was prepared first by extrusion, then by injection molding to obtain ...

Representation, space and Hollywood Squares: Looking at things that aren't there anymore [PDF]

, 2000
It has been argued that the human cognitive system is capable of using spatial indexes or oculomotor coordinates to relieve working memory load (Ballard, Hayhoe, Pook & Rao, 1997) track multiple moving items through occlusion (Scholl & Pylyshyn, 1999) or

Sequential dispersive measurement of a superconducting qubit

, 2020
We present a superconducting device that realizes the sequential measurement of a transmon qubit. The device disables common limitations of dispersive readout such as Purcell effect or transients in the cavity mode by turning on and off the coupling to ...

Magnetic-Field-Controlled Twin Boundaries Motion and Giant Magneto-Mechanical Effects in Ni-Mn-Ga Shape Memory Alloy

, 2000
Recently, several research groups have reported on the observation of super-large more than 5% magneto-strain effect in some non-stoichiometric Ni-Mn-Ga alloys close to 5.78% value expected from the tetragonality aspect ratio of the martensite crystal ...
