Impact of virtual reality use on the teaching and learning of vectors
Frontiers in Education, 2022 The use of virtual reality in education has enabled the possibility of representing abstract concepts and virtually manipulating them, providing a suitable platform for understanding mathematical concepts and their relation with the physical world.

EnergiesIn the existing literature, direct torque control (DTC) by synthesizing virtual vectors can effectively suppress low-order harmonic currents under the single open-phase fault (OPF) of the five-phase permanent magnet synchronous motor (PMSM), but the ...

Energies, 2021 The development of new control techniques for multiphase induction machines (IMs) has become a point of great interest to exploit the advantages of these machines compared to three-phase topology, for example, the reduced phase currents and lower ...

IEEE Access, 2022 The neutral-point clamped (NPC) inverter is widely used in energy conversion, but the unbalance of neutral-point voltage (NPV) will lead to imprecise control and the decline of power quality.

Homogenized Virtual Support Vector Machines [PDF]
Digital Image Computing: Techniques and Applications (DICTA'05), 2005 In many domains, reliable a priori knowledge exists that may be used to improve classifier performance. For example in handwritten digit recognition, such a priori knowledge may include classification invariance with respect to image translations and rotations. In this paper, we present a new generalisation of the Support Vector Machine (SVM) that aims

Virtual sensors for 2D vector field tomography [PDF]
Journal of the Optical Society of America A, 2010 We consider the application of tomography to the reconstruction of 2-D vector fields. The most convenient sensor configuration in such problems is the regular positioning along the domain boundary. However, the most accurate reconstructions are obtained by sampling uniformly the Radon parameter domain rather than the border of the reconstruction domain.

An improved seven-phase SVPWM modulation strategy based on virtual voltage vectors
Energy Reports, 2023 Seven-phase motors are usually powered by seven-phase voltage source inverter. The traditional seven-phase SVPWM algorithm produces a large common-mode voltage (CMV), while harmonic currents in the harmonic subspace can also produce large harmonic losses

The Pharmacophore Kernel for Virtual Screening with Support Vector Machines [PDF]
Journal of Chemical Information and Modeling, 2006 We introduce a family of positive definite kernels specifically optimized for the manipulation of 3D structures of molecules with kernel methods. The kernels are based on the comparison of the three-points pharmacophores present in the 3D structures of molecul es, a set of molecular features known to be particularly relevant for virtual screening ...
