Secure Beamforming for MIMO Broadcasting With Wireless Information and Power Transfer
(Elsevier, 2015-05)
We consider the Allen–Cahn equation Δu + u(1 − u2) = 0 in R3. We construct
two classes of axially symmetric solutions u = u(|x
|, x3) such that the (multiple)
components of the zero set look for large |x
| like catenoids, ...
A FINITE ELEMENT FOR FORM-FINDING AND STATIC ANALYSIS OF TENSEGRITY STRUCTURES
(Mathematical Science PublBerkeleyEUA, 2011)
Otimização topológica 3D sob restrição de tensão
(Revista Brasileira de Inovação Tecnológica em Saúde, 2013)
The Topology Optimization Problem consists in the total mass minimization of a structure. In order to solve three-dimensional stress problem, the Galerkin Finite Element Method was applied. It considers a four nodes ...
On non-coplanar Hohmann transfer using angles as parameters
(Springer, 2015)
We study a more complex case of Hohmann orbital
transfer of a satellite by considering non-coplanar and
elliptical orbits, instead of planar and circular orbits. We use
as parameter the angle between the initial and ...
Solução ponta a ponta em GPU do método sem malha local Petrov-Galerkin (MLPG)
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA ELÉTRICAPrograma de Pós-Graduação em Engenharia ElétricaUFMG, 2019-12-04)
This work presents an end-to-end massively parallelized procedure for the solution of boundary value problems on Graphics Processing Units (GPU). The proposal is an integrated strategy that not only entails the calculation ...
Restabelecimento multiobjetivo de sistemas de distribuição através de método híbrido de otimização

Approximated Mixed-Integer Convex Model for Phase Balancing in Three-Phase Electric Networks
(Cartagena de Indias, 2021-08-31)
With this study, we address the optimal phase balancing problem in three-phase networks
with asymmetric loads in reference to a mixed-integer quadratic convex (MIQC) model. The objective
function considers the minimization ...
An Efficient Mathematical Model for Distribution System Reconfiguration Using AMPL
(2021-01-01)
Distribution network is an essential part of electric power system, which however has higher power losses than transmission system. Distribution losses directly affect the operational cost of the system. Therefore, power ...
