Electrical and mechanical diagnostic indicators of wind turbine induction generator rotor faults [dataset]

Donatella Zappalá
In MW-sized wind turbines, the most widely-used generator is the wound rotor induction machine, with a partially-rated voltage source converter connected to the rotor. This generator is a significant cause of wind turbine fault modes. In this paper, a harmonic time-stepped generator model is applied to derive wound rotor induction generator electrical & mechanical signals for fault measurement, and propose simple closed-form analytical expressions to describe them. Predictions are then validated with tests on a...

Supporting data for: Optimal design of a toroidal field magnet system and cost of electricity implications for a tokamak using high temperature superconductors

T. S. Lee, I. Jenkins, Elizabeth Surrey & Damian Hampshire
The potential for reducing the Cost of Electricity (CoE) by using High Temperature Superconductors (HTS) in the Toroidal Field (TF) coils of a fusion tokamak power plant has been investigated using a new HTS module in the PROCESS systems code. We report the CoE and the design of HTS tokamaks that have been optimized by minimising the major radius of the plasma. Potential future improvements in both the superconducting properties and the structural materials for...

Data for "Dressed-state electromagnetically induced transparency for light storage in uniform phase spin-waves"

Nikola Šibalić
We present, experimentally and theoretically, a scheme for dressed-state electromagnetically induced transparency (EIT) in a three-step cascade system where a four-level system is mapped into an effective three-level system. Theoretical analysis reveals that the scheme provides coherent state control via adiabatic following and provides a generalized protocol for light storage in uniform phase spin-waves that are insensitive to motional dephasing. The three-step driving enables a number of other features including spatial selectivity of the excitation...

Coexistence of magnetic order and persistent spin dynamics in a quantum kagome antiferromagnet with no intersite mixing [dataset]

Andrej Zorko, Matej Pregelj, Martin Klanjšek, Matjaž Gomilšek, Zvonko Jagličić, James S. Lord, Joel A. T. Verezhak, Tian Shang, Wei Sun & Jin-Xiao Mi
One of the key questions concerning frustrated lattices that has lately emerged is the role of disorder in inducing spin-liquid-like properties. In this context, the quantum kagome antiferromagnet YCu3(OH)6Cl3, which has been recently reported as the first geometrically perfect realization of the kagome lattice with negligible magnetic/nonmagnetic intersite mixing and a possible quantum-spin-liquid ground state, is of particular interest. However, contrary to previous conjectures, here we show clear evidence of bulk magnetic ordering in this...

Data archive for Chem Comm paper | Furosemide's one little hydrogen atom: NMR crystallography structure verification of powdered molecular organics

Cory Widdifield
The potential of NMR crystallography to verify molecular crystal structures deposited in structural databases is evaluated, with two structures of the pharmaceutical furosemide serving as examples. While the structures differ in the placement of one H atom, using this approach, we verify one of the structures in the Cambridge Structural Database using quantitative tools, while establishing that the other structure does not meet the verification criteria.

Data for "Enhanced optical cross section via collective coupling of atomic dipoles in a 2D array"

Robert J. Bettles
Enhancing the optical cross section is an enticing goal in light-matter interactions, due to its fundamental role in quantum and non-linear optics. Here, we show how dipolar interactions can suppress off-axis scattering in a two-dimensional atomic array, leading to a subradiant collective mode where the optical cross section is enhanced by almost an order of magnitude. As a consequence, it is possible to attain an optical depth which implies high fidelity extinction, from a monolayer....

A high-order elliptic PDE based level set reinitialisation method using a discontinuous Galerkin discretisation [figure data]

Thomas Adams, Stefano Giani & William M Coombs
Abstract from paper: In this paper, an efficient, high-order accurate, level set reinitialisation method is proposed, based on the elliptic reinitialisation method (Basting and Kuzmin, 2013), which is discretised spatially using the discontinuous Galerkin (DG) symmetric interior penalty method (SIPG). In order to achieve this a number of improvements have been made to the elliptic reinitialisation method including; reformulation of the underlying minimisation problem driving the solution; adoption of a Lagrange multiplier approach for enforcing...

Examining charge transport networks in organic bulk heterojunction photovoltaic diodes using 1/f noise spectroscopy (data files)

K. Kaku, A.T. Williams, B. Mendis & C. Groves
This study investigates the application of 1/f noise spectroscopy to determine the morphology of organic photovoltaic diodes. Our experiments indicate that 1/f noise spectroscopy can provide detailed information about charge transport networks in such complex, bulk heterojunction devices, even when bipolar charge transport is present. This indicates that 1/f noise spectroscopy could be used to investigate morphology in a wide range blended organic electronic devices. Methodologies and descriptions of the data are described in full...

Wafer Defect Microscopy Enhancement using Perceptually Motivated Super-Resolution Convolutional Neural Networks [dataset]

Russell Maguire
The silicon super-resolution (SiSR) network is a new convolutional neural network for enhancing the inspection of defects in silicon devices. This paper demonstrates how the proposed SiSR network is able to upscale microscopy images of patterns and defects by x4 in each direction, aiding inspection in small--medium scale device fabrication. The alignment cameras of a laser-writer were repurposed to capture a large dataset of patterned wafer microscopy examples at two different magnification factors, but small...
