Shape-Memory Polymeric Artificial Muscles: Mechanisms, Applications and Challenges

open access: yesMolecules, 2020
Shape-memory materials are smart materials that can remember an original shape and return to their unique state from a deformed secondary shape in the presence of an appropriate stimulus.

Shape From Focus Based on Depth Estimation Confidence [PDF]

open access: yesJisuanji gongcheng
Shape From Focus (SFF) is an important technique in the field of non-contact 3D reconstruction. Owing to the influence of the environment and the limitations of the camera, the image acquisition process inevitably generates noise, which affects the ...

A Novel Multi-Focus Image Fusion Network with U-Shape Structure

open access: yesSensors, 2020
Multi-focus image fusion has become a very practical image processing task. It uses multiple images focused on various depth planes to create an all-in-focus image.

Influence of electrode geometry on X-ray emission, plasma inductance, voltage, and current derivative signals obtained from a plasma focus device

open access: yesResults in Physics, 2021
Plasma focus devices have been investigated as a pulsed radiation source. Different studies have shown that the shape of the anode affects strongly the plasma dynamic and X-ray emission that takes place in plasma focus devices.

On a shape adaptive image ray transform

open access: yes, 2013
A conventional approach to image analysis is to perform separately feature extraction at a low level (such as edge detection) and follow this with high level feature extraction to determine structure (e.g.

Focus Estimation Methods for Use in Industrial SFF Imaging Systems

open access: yesApplied Sciences
A Shape-From-Focus (SFF) is a three-dimensional imaging method based on focus information. It is not yet widely used for in-line industrial inspection or measurement tasks.

Depth and Shape Estimation from Focus in Scanning Electron Microscope for Micromanipulation.

open access: yes, 2013
International audienceInter-object depth estimation is always a major concern for micromanipulation using scanning electron microscope (SEM). So far, various methods have been proposed for estimating this depth based on stereoscopic imaging. Most of them

Beyond resistance: social factors in the general public response to pandemic influenza [PDF]

open access: yes, 2015
Background: Influencing the general public response to pandemics is a public health priority. There is a prevailing view, however, that the general public is resistant to communications on pandemic influenza and that behavioural responses to the 2009/10 ...

Partial-Wave Analysis of Single-Pion Production Reactions

open access: yes, 2006
We present an overview of our efforts to analyze pion-nucleon elastic scattering data, along with data from related photo- and electroproduction reactions, in order to study the baryon spectrum. We then focus on the Delta(1232) resonance.

Constructions of health, weight and bodily appearance among Indo-Fijian women across three generations : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Psychology at Massey University [PDF]

open access: yes, 2014
Discursive constructions of a 'thin ideal' body shape today have often associated the slender body to the idea of a 'healthy weight' and physical beauty.
