In order to adapt to the requirements of the development for precision agriculture technology, making the rice seed tape planting technology has been widely used. The paper-making improved the design on the rice seed tape twisting machine especially the seed tape winding units. It proposed seed tape winding automatic control system based on STC90C514AD to realize the rotating speed adjustment o...

The success of health monitoring and condition assessment of power transformers based on winding current signature analysis lies on proper extraction of features. The extraction of features in turn depends on appropriate signal processing methods. Fourier based signal analysis provides only frequency information and also suitable only for stationary signals. In this paper we present a combined ...

We investigate the development of winding number and Chern-Simons number in a tachyonic transition in the SU(2) Higgs model, motivated by the scenario of cold electroweak baryogenesis. We find that localized configurations with approximately halfinteger winding number, dubbed half-knots, play an important role in this process. When the Chern-Simons number adjusts locally to the winding number, ...

Induced uncertainties during the filament winding process may cause a significant stochastic variation in mechanical behaviour of composite shells. This paper aims to develop novel and deep uncertainty quantification (UQ), sensitivity reliability analyses wound shells considering manufacturing uncertainties. Firstly, progressive damage analysis is performed estimate their deterministic burst pr...

To date, programs available for the simulation of electromagnetic transients in power components and networks do not include transformer winding models able to simulate an impulse test response. This is an important omission, since the standard impulse test defines for most cases the highest dielectric stress that a power transformer will suffer once installed. In this work, two transformer win...

A method for robotized cable winding of the Uppsala University Wave Energy Converter generator stator has previously been presented and validated. The purpose of this study is to present and validate further developments to the method: automated stand-alone equipment for the preparation of the winding cables. The cable preparation consists of three parts: feeding the cable from a drum, forming ...

The density of extended topological defects created during symmetry breaking phase transitions depends on the ratio between the correlation length in the symmetric phase near Tc and the winding length of the defects as determined by the momentaneous effective action after a typical relaxation time. Conservation of winding number in numerical simulations requires a suitable embedding of the fiel...

Improvement of diagnostic methods for both power and distribution transformers is crucial considering the part they play in electrical networks as well as their cost. Transfer function based testing of transformers is one of the methods that has been introduced recently. This method enables the identification of winding deformations resulting from the short circuit currents and winding dislocat...
