O método do Gradient Sampling com comprimento de passo limitado aplicado ao problema de determinação das condições de equilíbrio operacionais de sistemas dinâmicos
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA ELÉTRICAPrograma de Pós-Graduação em Engenharia ElétricaUFMG, 2018-12-19)
In this Master Dissertation, it is proposed to restrict (limit) the search direction of the Gradient Sampling method, which means to add a box constraint to each quadratic optimization sub-problem. It is called Gradient ...
Use of thermal gradients for control of vortex matter in mesoscopic superconductors
(2019-07-11)
Usually, the measurements of electronic and magnetic properties of superconducting samples are carried out under a constant temperature bath. On the other hand, thermal gradients induce local variation of the superconducting ...
The ACS Fornax Cluster Survey. X. Color Gradients of Globular Cluster Systems in Early-type Galaxies
(2011)
We use the largest homogeneous sample of globular clusters (GCs), drawn from the ACSVCS and ACSFCS, to investigate the color gradients of GC systems in 76 early-type galaxies. We find that most GC systems possess an obvious ...
UAV-based air pollutant source localization using gradient and probabilistic methods
(Institute of Electrical and Electronics Engineers Inc., 2018)
This work proposes an algorithm for air pollutant source localization using an Unmanned Aerial Vehicle (UAV). The algorithm combines a gradient-based search with a probabilistic method to localize the pollutant source. The ...
On The Differentiability Check In Gradient Sampling Methods

The role of climate on floristic composition in a latitudinal gradient in the Brazilian atlantic forest
(2018-11-01)
Background and aims – Latitudinal gradients have an important influence on species distribution reflecting the effects of environmental factors such as temperature, rainfall, soil, and geographical distance. In the ...

A comunidade de Braconidae (Hymenoptera; Ichneumonoidea) em um gradiente altitudinal no Parque Nacional do Itatiaia, RJ: taxonomia, distribuição e diversidade
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERNCâmpus São Carlos, 2016-06-15)
In Brazil, there are few studies on mountain ecosystems that aims the biodiversity
conservation, even with hymenoptera parasitoids, especially the family Braconidae, a group
ecologically important, because they represent ...
Determinação do perfil térmico em amostras de aço AISI M35 imersas em plasma
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ciência e Engenharia de MateriaisProcessamento de Materiais a partir do Pó; Polímeros e Compósitos; Processamento de Materiais a part, 2007-03-22)
The heat transfer between plasma and a solid occurs mostly due the radiation and the collision of the particles on the material surface, heating the material from the surface to the bulk. The thermal gradient inside the ...
