A Three-level Space Vector PWM Strategy Based on Variable Virtual Middle Vector [PDF]
T-type three-level topology has been widely applied in power converters for its high efficiency and low output harmonics, and the performance of this converter is determined by the effect of its capacitor neutral point voltage control.

Montage as a narrative vector for virtual reality experiences [PDF]
The goal of our paper is to demonstrate through artistic experimentation that the concept of montage can be an effective vector for conveying complex narratives in immersive, room-scale virtual reality experiences. We review the particularities of virtual reality mediations regarding narrative, and we propose the new conceptual framework of « spatial ...

The Conventional model predictive control (C-MPC) uses only a single voltage vector in each control period, resulting in poor control performance. In addition, the computational burden in discrete space state generated by three-level inverter cannot be ...

Virtual sensors for 2D vector field tomography [PDF]
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.

The Pharmacophore Kernel for Virtual Screening with Support Vector Machines [PDF]
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 ...

An improved seven-phase SVPWM modulation strategy based on virtual voltage vectors
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

Virtual Screening with Support Vector Machines and Structure Kernels [PDF]
Support vector machines and kernel methods have recently gained considerable attention in chemoinformatics. They offer generally good performance for problems of supervised classification or regression, and provide a flexible and computationally efficient framework to include relevant information and prior knowledge about the data and problems to be ...
