Elimination and recursions in the scattering equations
(2016-05-10)
We use the elimination theory to explicitly construct the (n-3)! order polynomial in one of the variables of the scattering equations. The answer can be given either in terms of a determinant of Sylvester type of dimension ...
Challenges for malaria elimination in Brazil
(BioMed Central, 2016)
Abstract
Brazil currently contributes 42 % of all malaria cases reported in the Latin America and the Caribbean, a region where major progress towards malaria elimination has been achieved in recent years. ...
Conditions for Offset Elimination in State Space Receding Horizon Controllers: A Tutorial Analysis
(Elsevier, 2008-12)
An offset-free control is one that drives the controlled outputs to their desired targets at steady state. In the linear model predictive control (MPC) framework, the elimination of steady-state offset may seem a little ...

Técnica de controle e sincronismo aplicada a conversor NPC utilizando eliminação seletiva de harmônicas
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2019-12-09)
This work has the propose of using the Selective Harmonic Elimination (SHE) modulation technique applied to a three-phase converter connected to the power grid to operate at high power. Through a dq coordinates transformation ...
Fibers of multi-graded rational maps and orthogonal projection onto rational surfaces
(Society for Industrial and Applied Mathematics, 2020-06)
We contribute a new algebraic method for computing the orthogonal projections of a point onto a rational algebraic surface embedded in the three-dimensional projective space. This problem is first turned into the computation ...
Não-normalidade multivariada e multicolinearidade em análise de trilha na cultura de milho
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Agronomia, 2012-02-16)
The path analysis allows evaluation of the direct and indirect effects of the explicative variables on variable of interest, through the breakdown of the correlation coefficients. In order to make the results obtained ...
Effective differential Nullstellensatz for ordinary DAE systems with constant coefficients
(Academic Press Inc Elsevier Science, 2014-10)
We give upper bounds for the differential Nullstellensatz in the case of ordinary systems of differential algebraic equations over any field of constants K of characteristic 0. Let x be a set of n differential variables, ...
Study of the roto-orbital motion using intermediaries: numerical experiments
(2019-06-01)
The purpose of the present study is to test two recently proposed integrable models to study the roto-orbital motion of an axisymmetric rigid body, considering this body under the influence of a central gravitational field. ...
