Model predictive current control of six-phase induction motor drives using virtual vectors and space vector modulation

open access: yes, 2022
The use of multiphase machines has become a suitable choice in high-performance industry applications through advantages such as lesser torque ripple, enhanced current distribution per phase, and fault-tolerance capability.

Vector mesons and (virtual) nuclear optics

open access: yesPhysics Letters B, 1974
Abstract Nuclear photoproduction and inelastic electron-nucleus scattering at high energies are investigated in the framework of a scaling model of electromagnetic interactions which has been recently proposed. No shadowing is predicted to take place for large q2. Our results are in agreement with the available experimental data.

Vector logic allows counterfactual virtualization by the square root of NOT [PDF]

open access: yesLogic Journal of the IGPL, 2020
AbstractIn this work, we investigate the representation of counterfactual conditionals using the vector logic, a matrix-vector formalism for logical functions and truth values. Inside this formalism, the counterfactuals can be transformed in complex matrices preprocessing an implication matrix with one of the square roots of NOT, a complex matrix. This

Visualization of Vector Field by Virtual Reality [PDF]

open access: yesProgress of Theoretical Physics Supplement, 2000
A visualization software program is developed in order to analyze three dimensional vector fields by means of today’s advanced virtual reality technology. This program enables simulation researchers to interactively visualize stream lines, tracer particle motions, isosurfaces, etc. with stereo view.

Multi-Virtual-Vector-Based Predictive Current Control for Fault-Tolerant Inverter-Fed Dual Three-Phase Permanent Magnet Synchronous Machines

open access: yes, 2023
Dual three-phase permanent magnet synchronous machine (DTP-PMSM) has received extensive interests due to its inherent fault-tolerant capability. However, conventional single-virtual-vector-based predictive current control (SVV-PCC) for DTP-PMSM with open-

Virtual Vector Machine for Bayesian Online Classification [PDF]

open access: yesCoRR, 2012
In a typical online learning scenario, a learner is required to process a large data stream using a small memory buffer. Such a requirement is usually in conflict with a learner's primary pursuit of prediction accuracy. To address this dilemma, we introduce a novel Bayesian online classi cation algorithm, called the Virtual Vector Machine.
