Polyethylene-Based Carbon Fibers by the Use of Sulphonation for Stabilization

Fibers, 2015
Polyethylene has great potential as an alternative material for carbon fiber production. Polyethylene can be processed in the economic melt spinning process. These precursors are prepared for the subsequent process step of carbonization by using chemical

Realization of an Automated Vertical Warp Stop Motion Positioning

Actuators, 2015
The tension in the warp yarns is a critical variable in the weaving process. If the warp tension is too high or too low the weaving process will be interrupted. A parameter that directly affects the warp tension is the vertical warp stop motion position.

Information Field Theory for Two Applications in Astroparticle Physics

Particles
Information field theory (IFT) provides a powerful framework for reconstructing continuous fields from noisy and sparse data. Based on Bayesian statistics, IFT allows for the approximation of posterior distributions over field-like parameter spaces in ...

A Review on False-Twist Texturing

Fibers
The annual demand for fibres continues to rise worldwide. Consequently, more and more fibres must be produced to meet this demand, most of which are melt-spun polymeric man-made fibres.

Multiple assembly strategies for silica aerogel-fiber combinations – A review

Materials & Design, 2022
Silica aerogels have a unique structure that makes them promising materials for variable applications. However, they are brittle due to weak inter-particle necks, and also expensive.

Neurobehavioral Assessment of Sensorimotor Function in Autism Using Smartphone Technology

Autism Research, EarlyView.
ABSTRACT Differences in sensorimotor processing represent an important, yet underrecognized, feature of autism; typically assessed through subjective observations, which, although important, are susceptible to biases. To complement these observations, a more objective approach to assess sensorimotor function may be possible through reflex‐based ...

Audit Certainty, Audit Productivity, and Taxpayer Compliance [PDF]

, 2005
Strategies for dealing with evasion include such standard policies as stricter enforcement (e.g., increased audit rates, more extensive audits, larger penalties). However, the exact responses of taxpayers to these enforcement measures are quite difficult
