Improving image classification through descriptor combination
(2012-12-01)
The efficiency in image classification tasks can be improved using combined information provided by several sources, such as shape, color, and texture visual properties. Although many works proposed to combine different ...

A simplified Space-Vector modulation algorithm for four-leg NPC converters
(IEEE Inst Electrical and Electronic Engineering Inc., 2017)
To interface generation sources and loads to fourwire distribution networks it is important to use power converters and modulation methods, which provide high performance, flexibility, and reliability. To achieve these ...
Pasting and reversing operations over some vector spaces
(Boletín de Matemáticas, 2013)
Pasting and Reversing operations have been used successfully over the set of integer numbers, simple permutations, rings and recently over a generalized vector product. In this paper, these operations are defined from a ...
Quem tem mais pontos, o círculo ou a reta?
(Universidade Federal do Rio Grande do NorteBrasilUFRNLicenciatura em Matemática, 2017-12-08)
This paper aims to enunciate and demonstrate important peculiar results that occur
in metric spaces. For this, it is used the bibliographical research, with which a study
and survey was made on the metric spaces, sequences ...

Stratifications on the Nilpotent Cone of the moduli space of Hitchin pairs
(2020)
We consider the problem of finding the limit at infinity (corresponding to
the downward Morse flow) of a Higgs bundle in the nilpotent cone under the natural

TRI-STATE SPACE VECTOR MODULATION FOR THREE-PHASE INTEGRATED INVERTERS
(Ieee, 2011-01-01)
The aim of this work is to present a modified Space Vector Modulation (SVM) suitable for Tri-state Three-phase inverters. A standard SVM algorithm and the Tri-state PWM (Pulse Width Modulation) are presented and their ...
