High torque ripple dramatically affects the switched reluctance motor (SRM) application. To reduce ripple, a reference neural network (RTNN) is proposed to adjust online. Firstly, RTNN built on sharing function (TSF) method. Furthermore, designed as single-input and -output network. As periodic relationship between rotor angle, angle constitutes central node parameter of implicit in RTNN. There...

General energy demand is continuously increasing, thus the generating assets need to be optimised for higher efficiency. Wind turbines are no exception. Their maximum efficiency can determined on a theoretical basis. The limit approached by researches day day, utilizing latest developments in airfoil design, blade structure and new improved ideas conventional unconventional wind turbine layouts...

For a rotatory dual-head positron emission tomography (PET) system, how to determine the rotation increments is an open problem. In this study, we simulated the characteristics of a rotatory dual-head PET system. The influences of different rotation increments were compared and analyzed. Based on this simulation, the imaging performance of a prototype system was verified. A reconstruction flowc...

Blade-tip vortices and their interaction with the helicopter blades play an important role in the generation of noise on rotorcrafts. Full-scale vortex visualization is essential for the understanding of these effects and the validation of sub-scale experiments and numerical simulations. In the present work, the reference-free Background Oriented Schlieren (BOS) method was used to visualize bla...

The cover image is based on the Research Article Dual mechanical port power distribution in dual rotor permanent magnet flux switching generator for counter-rotating wind turbine applications by Wasiq Ullah et al., https://doi.org/10.1049/rpg2.12450.

Indicator-geostatistics based super-resolution mapping (IGSRM) is a popular super-resolution mapping (SRM) method. Unlike most existing SRM methods that produce only one SRM result each, IGSRM generates multiple equally plausible super-resolution realizations (i.e., SRM results). However, multiple super-resolution realizations are not desirable in many applications, where only one SRM result is...

this work deals with effects of asymmetric stiffness on the dynamic behaviour of the rotor system. the analysis is presented through an extended lagrangian hamiltonian mechanics on the asymmetric rotor system, where symmetries are broken in terms of the rotor stiffness. the complete dynamics of asymmetries of rotor system is investigated with a case study. in this work, a mathematical model is ...

Misalignment fault is the main factor that affects normal running of dual-rotor system. Quantitative identification misalignment an important way to ensure safe and stable service system, while accuracy traditional methods low. Aiming at above problems, this paper proposed a quantitative method based on DBN D-S evidence theory improved by mutual information measure (MIMD-S). Seven groups experi...

Well-characterized certified reference materials are needed by laboratories in the food testing, dietary supplement, and nutrition communities to facilitate compliance with labeling laws and improve the accuracy of information provided on product labels, so that consumers can make good choices. As a result of the enactment of the Nutrition Labeling and Education Act of 1990 and the Infant Formu...

In 2014, the Nobel Prize in Chemistry was awarded to three scientists who have made groundbreaking contributions to the field of superresolution (SR) microscopy (SRM). The first commercial SR microscope came to market a decade earlier, and many other commercial options have followed. As commercialization has lowered the barrier to using SRM and the awarding of the Nobel Prize has drawn attentio...
