Production of Core Spun Yarn with Ring & Siro Spinning System

A common problem in production of core–spun yarns on the Ring spinning frame is the slippage of the staple fibers as sheath fibers relative to the core. This effect is known as ‘strip-back’ or barberpole. This problem may lead to an incomplete core coverage and results in end–breaks in subsequent processing. In order to avoid this problem, in the present work, core spun yarns (acrylic sheath fi...

Distribution of Power Requirements during Yarn Winding in Ring Spinning

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

YARN: Spinning-in-Progress

YARN (Yet Another RussNet), a project started in 2013, aims at creating a large open WordNet-like thesaurus for Russian by means of crowdsourcing. The first stage of the project was to create noun synsets. Currently, the resource comprises 100K+ word entries and 46K+ synsets. More than 200 people have taken part in assembling synsets throughout the project. The paper describes the linguistic, t...

Design and Parameters Optimization of Pteris vittata Automatic Sowing Machine for Phytoremediation

In view of the uneven artificial sowing, low sowing, as well as the fact that the existing seeders cannot meet the sowing requirements of Pteris vittata, this paper designed an automatic plug seeder by using the method of spraying and sowing after mixing spores and water. In order to obtain the optimum working parameters of the seeder, response surface method (RSM) was employed to desi...
