Robust adaptive beamforming using a Bayesian steering vector error model [PDF]

, 2013
We propose a Bayesian approach to robust adaptive beamforming which entails considering the steering vector of interest as a random variable with some prior distribution.

O fragmentado e tortuoso processo de construção dos conceitos de vetor e escalar

Revista Brasileira de Ensino de Física
O presente trabalho é uma tentativa de chamar a atenção para a forma inadequada da construção dos conceitos de vetor e escalar apresentados na maioria dos livros de física no nível universitário.

Partitions of a vector space

Discrete Mathematics, 1980
Partitions of groups have been studied by several authors. J.W. Young proved in [6] that if an abelian group has a non-trivial partition, the group must be an elementary abelian p-group. Since such a group can be represented as the additive group of some V,,(p) -and U is a subgroup of V,(p) iff U is a subspace of V,(p) partitions of V,(q) is a ...

A Novel SVPWM Algorithm for 3-phase 3-level Converter

Kongzhi Yu Xinxi Jishu, 2011
As for the three-phase three-level voltage source converter, a simple SVPWM algorithm based on the sector mapping for controlling three-level converter is proposed. Correctness of the algorithm is verified by the simulation results.

Menger probabilistic normed space is a category topological vector space [PDF]

Sahand Communications in Mathematical Analysis, 2016
In this paper, we formalize the Menger probabilistic normed space as a category in which its objects are the Menger probabilistic normed spaces and its morphisms are fuzzy continuous operators.

Direct Power Control Strategy based on Space Vector Modulation

Kongzhi Yu Xinxi Jishu, 2010
Direct power control technology is applied on three-phase PWM rectifier. Using space vector modulation instead of switching tables can eliminate the bad effect of unconstant switching frequency on the rectifier.

On the geometry of rank two vector bundles and two-theta divisors on a curve [PDF]

, 2003
This thesis aims at presenting results and remarks concerning the study of subvarieties of the projective space |2Ɵ| associated to a smooth projective curve C of genus at least 3 and its connections to the moduli space SU(_c)(2) of rank 2 semi-stable ...

Production Equilibria in Vector Lattices [PDF]

The general purpose of this paper is to prove quasiequilibrium existence theorems for production economies with general consumption sets in an infinite dimensional commodity space, without assuming any monotonicity of preferences or free-disposal in ...

Space Vector Design Assisted Channel Modulation

IEEE Access
With the design idea of the index modulation (IM), media-based modulation (MBM) has been attracted a lot of attention due to that it not only offers optional transmission channels for physical security but also transmits additional channel index (CI ...
