We describe the concept, fabrication, and most relevant properties of a piezoelectric-polymer system: Two fluoroethylenepropylene (FEP) films with good electret are laminated around specifically designed prepared polytetrafluoroethylene (PTFE) template at 300 °C. After removing PTFE template, two-layer FEP film open tubular channels is obtained. For electric charging, system subjected to high field. The resulting dielectric barrier discharges inside yield ferroelectret piezoelectricity. d33...

Electroactive polymers are soft capacitors made of thin elastic and electrically insulating films coated with compliant electrodes offering a large amount deformation. They can either be used as actuators by applying an electric charge or energy converters based on the electrostatic principle. These unique properties enable industrial development highly efficient environmentally sustainable converters, which opens up possibility to further exploit renewable inexhaustible sources like wind...

A classifier which is capable of distinguishing a syntactically well formed sentence from ill one has the potential to be useful in an L2 language-learning context. In this article, we describe classifies English sentences as either or using information gleaned three different natural language processing techniques. We issues involved acquiring data train such and present experimental results for on variety sentences. demonstrate that (a) combination linguistic sources helpful, (b) trade-off...

This paper describes the DCU-UVT team's participation in Language Identification Code-Switched Data shared task Workshop on Computational Approaches to Code Switching.Wordlevel classification experiments were carried out using a simple dictionary-based method, linear kernel support vector machines (SVMs) with and without contextual clues, k-nearest neighbour approach.Based these experiments, we select our SVM-based system clues as final present results for Nepali-English Spanish-English datasets.

We present a robust parser which is trained on treebank of ungrammatical sentences. The created automatically by modifying Penn sentences so that they contain one or more syntactic errors. evaluate an existing Penn-treebank-trained the to see how it reacts noise in form grammatical re-train this training section treebank, leading significantly improved performance test sets. show classifier can be used prevent degradation original data.

Multilingual users of social media sometimes use multiple languages during conversation.Mixing in content is known as code-mixing.We annotate a subset trilingual code-mixed corpus (Barman et al., 2014) with part-of-speech (POS) tags.We investigate two state-of-the-art POS tagging techniques for and combine the features systems to build better tagger.Furthermore, we joint model which performs language identification (LID) partof-speech simultaneously.

Abstract An electret is a dielectric material exhibiting quasi‐permanent electric charge. The aim of this work to give access PC materials with distinctly improved performance. In context, the charge storage capabilities corona charged films several grades were investigated by isothermal potential decay measurements at 90 °C. most promising grade was further new class bisimide additives. best additive efficient concentration in combination physical aging step yielded excellent electrets...

Abstract In a translation workflow, machine (MT) is almost always followed by human post-editing step, where the raw MT output corrected to meet required quality standards. To reduce number of errors translators need correct, automatic (APE) methods have been developed and deployed in such workflows. With advances deep learning, neural APE (NPE) systems outranked more traditional, statistical, ones. However, plethora options, variables settings, as well relation between NPE performance...

Dielectric elastomer actuators (DEAs) can be optimized by modifying the dielectric or mechanical properties of electroactive polymer. In this work both were improved simultaneously a simple process, one-step film formation for polyurethane and silicone films. The network contains polydimethylsiloxane (PDMS) chains, as well cross-linker grafted molecular dipoles in varying amounts. process leads to films, which are homogenous down level show higher permittivities reduced stiffnesses. dipole...
