The Journal of Engineering, 2019 This paper proposes a space vector pulse width modulation (SVPWM) technique to eliminate common mode voltage (CMV) and common mode current for dual-inverter six-phase open-end winding PMSM motor drive fed from a single DC supply.

Vector-Based Seismic Decomposition by Reverse Time Methods
Russian Journal of Earth Sciences, 2023 The paper analyzes the decomposition of the initial seismic data by the methods of wave reversal in time when constructing seismic attributes. Within the framework of a formal approach to decomposition, as a mapping of data from one space into data of a ...

Extension of Matrix Pencil Reduction to Abelian Categories
, 2017 Matrix pencils, or pairs of matrices, are used in a variety of applications. By the Kronecker decomposition Theorem, they admit a normal form. This normal form consists of four parts, one part based on the Jordan canonical form, one part made of ...

Distributive decomposition of near-vector spaces
Journal of Algebra and Its ApplicationsThis paper characterizes the regularity of arbitrary near-vector spaces by representing them as direct sums of vector spaces over division rings formed by distributive elements. This approach allows us to define the dimension of a near-vector space in terms of the dimensions of these summands, providing new insights into the structure and properties ...

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Analysis of astrometric catalogues with vector spherical harmonics
, 2012 Comparison of stellar catalogues with position and proper motion components using a decomposition on a set of orthogonal vector spherical harmonics. We show the theoretical and practical advantages of this technique as a result of invariance properties ...

Series representations in spaces of vector‐valued functions via Schauder decompositions [PDF]
Mathematische Nachrichten, 2020 AbstractIt is a classical result that every ‐valued holomorphic function has a local power series representation. This even remains true for holomorphic functions with values in a locally complete locally convex Hausdorff spaceEover . Motivated by this example we try to answer the following question. LetEbe a locally convex Hausdorff space over a field

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Glioma recurrence severely impacts patient prognosis, with current treatments showing limited efficacy. Traditional methods struggle to analyze recurrence mechanisms due to challenges in assessing tumor heterogeneity, spatial dynamics, and gene networks.

International Journal of Adaptive Control and Signal Processing, EarlyView.This paper proposes two projector‐based Hopfield neural network (HNN) estimators for online, constrained parameter estimation under time‐varying data, additive disturbances, and slowly drifting physical parameters. The first is a constraint‐aware HNN that enforces linear equalities and inequalities (via slack neurons) and continuously tracks the ...
