On the risk of failure to prevent induction motors permanent damage, due to the short available time‐to‐diagnosis of inter‐turn short‐circuit faults

open access: yesIET Electric Power Applications, 2021
As one of the most important assets of the industry, it is crucial to fully characterise all failure modes showing potential to degrade the normal operation of induction motors (IMs).

Supervised Machine Learning Classification for Short Straddles on the S&P500

open access: yesRisks, 2022
In this paper, we apply machine learning models to execute certain short-option strategies on the S&P500. In particular, we formulate and focus on a supervised classification task which decides if a plain short straddle on the S&P500 should be executed ...

TIME MACHINES AND QUANTUM THEORY [PDF]

open access: yesThe Eleventh Marcel Grossmann Meeting, 2008
There is a deep structural link between acausal spacetimes and quantum theory. As a consequence quantum theory may resolve some "paradoxes" of time travel. Conversely, non-time-orientable spacetimes naturally give rise to electric charges and spin half.

On Halting Process of Quantum Turing Machine

open access: yes, 2003
We prove that there is no algorithm to tell whether an arbitrarily constructed Quantum Turing Machine has same time steps for different branches of computation. We, hence, can not avoid the notion of halting to be probabilistic in Quantum Turing Machine.

Fast iron loss prediction method in the pre-design stage of SRMs

open access: yesThe Journal of Engineering, 2019
To effectively find a valid solution in the development process of electrical machines, it is essential to predict machine iron loss in the pre-design stage. In guidance on the choice of the most suitable configuration of the switched reluctance machine (

RG inspired Machine Learning for lattice field theory

open access: yes, 2017
Machine learning has been a fast growing field of research in several areas dealing with large datasets. We report recent attempts to use Renormalization Group (RG) ideas in the context of machine learning.

Quantum-chemical insights from deep tensor neural networks

open access: yesNature Communications, 2017
Machine learning is an increasingly popular approach to analyse data and make predictions. Here the authors develop a ‘deep learning’ framework for quantitative predictions and qualitative understanding of quantum-mechanical observables of chemical ...
