Improving Legibility of Motor Current Spectrum for Broken Rotor Bars Fault Diagnostics
Electrical, Control and Communication Engineering, 2019 In this paper, the harmonic contribution of the broken rotor bar of an induction machine is investigated using an effective combination of the fast Fourier transform (FFT) and a band stop filter.

From the conformal anomaly to the Virasoro algebra
Proceedings of the London Mathematical Society, Volume 130, Issue 4, April 2025.Abstract The conformal anomaly and the Virasoro algebra are fundamental aspects of two‐dimensional conformal field theory and conformally covariant models in planar random geometry. In this article, we explicitly derive the Virasoro algebra from an axiomatization of the conformal anomaly in terms of real determinant lines, one‐dimensional vector spaces

Moduli of parabolic sheaves on a polarized logarithmic scheme [PDF]
, 2015 We generalize the construction of moduli spaces of parabolic sheaves given by Maruyama and Yokogawa in [MY92] to the case of a projective fine saturated log scheme with a fixed global chart.

From GPU to CPU (and Beyond): Extending Hardware Support in GPUSPH Through a SYCL‐Inspired Interface
Concurrency and Computation: Practice and Experience, Volume 37, Issue 1, 10 January 2025.ABSTRACT While most software is originally designed for serial or parallel execution on CPU, and porting to GPU comes later in its development, GPUSPH was designed from the ground up to run on GPUs using CUDA. Making it accessible to a wider audience by introducing support for other computational hardware, and in particular CPUs, poses challenges that ...

Radio Galaxy Zoo: Knowledge Transfer Using Rotationally Invariant Self-Organising Maps
, 2019 With the advent of large scale surveys the manual analysis and classification of individual radio source morphologies is rendered impossible as existing approaches do not scale.

Finite-size scaling of the Shannon-Rényi entropy in two-dimensional systems with spontaneously broken continuous symmetry [PDF]
, 2016 We study the scaling of the (basis-dependent) Shannon entropy for two-dimensional quantum antiferromagnets with Neel long-range order. We use a massless free-field description of the gapless spin wave modes and phase space arguments to treat the fact ...

Journal of the London Mathematical Society, Volume 110, Issue 5, November 2024.Abstract For a log Calabi Yau pair (X,D$X,D$) with X∖D$X\setminus D$ smooth affine, satisfying either a maximal degeneracy assumption or contains a Zariski dense torus, we prove under the condition that D is the support of a nef divisor that the structure constants defining a trace form on the mirror algebra constructed by Gross–Siebert are given by ...

Anomalies and entanglement renormalization
, 2017 We study 't Hooft anomalies of discrete groups in the framework of (1+1)-dimensional multiscale entanglement renormalization ansatz states on the lattice. Using matrix product operators, general topological restrictions on conformal data are derived.

Quasi-Topological Phases of Matter and Topological Protection
, 2012 We discuss systems which have some, but not all of the hallmarks of topological phases. These systems' topological character is not fully captured by a local order parameter, but they are also not fully described at low energies by topological quantum ...
