Three-dimensional effect of stresses in open stope mine design
(Taylor and Francis Ltd., 2018)
The stability graph method is widely used for open stope mine design. During the development of the method the effect of induced stresses were included by using two-dimensional or limited three-dimensional stress analysis. ...
Stability assessment of underground mine stopes subjected to stress relaxation
(Taylor & Francis, 2020)
Stress relaxation plays an important role in the design of underground stopes. The aim of this paper is to assess the stope stability in connection with the stress relaxation using a classification approach. Three types ...
Robust Multi-class Graph Transduction with higher order regularization
(International Neural Network Society - INNSIEEE Computational Intelligence SocietyKillarney, 2015-07)
Graph transduction refers to a family of algorithms that learn from both labeled and unlabeled examples using a weighted graph and scarce label information via regularization or label propagation. A recent empirical study ...
GRASP/VND Optimization Algorithms for Hard Combinatorial Problems
(Udelar.FI, 2019)
Two hard combinatorial problems are addressed in this thesis. The first one is known as the ”Max CutClique”, a combinatorial problem introduced by P. Martins in 2012. Given a simple graph, the goal is to
find a clique C ...
Modelagem baseada em grafos para sistemas de controle descritos por espaços de estados
(Universidade Tecnológica Federal do ParanáToledoBrasilEngenharia de ComputaçãoUTFPR, 2021-08-20)
In this work, a graph-based method is proposed to represent control systems described by state spaces. For this purpose, it is described the study of graph topological structures, which qualify and quantify the relations ...
An experimental analysis on time series transductive classification on graphs
(International Neural Network Society – INNSIEEE Computational Intelligence SocietyKillarney, 2015-07)
Graph-based semi-supervised learning (SSL) algorithms perform well when the data lie on a low-dimensional manifold. Although these methods achieved satisfactory performance on a variety of domains, they have not been ...
Hamming Graph based Image Compression with variable Threshold
(ICGST, 2015-06-12)
In this paper a lossy image compression methodusing the adjacency matrix of a graph is proposed.We instantiate the method using the Hamming graph,which gives rise to an image compression algorithmthat uses a Hadamard Matrix ...
Mutagraph: modelos e algoritmos para predição na afinidade de complexos proteicos através de Graph Kernel e métricas de redes complexas
(Universidade Federal de Minas GeraisUFMG, 2017-11-07)
Mutations in coding regions can aect the structure and the function of a protein leading to malfunction and still related to hereditary disorders and propensity to several cancers. Missense mutation types, where have the ...
Dimensionamento empírico de realce em Sublevel Stoping
(Universidade Federal de Minas GeraisUFMG, 2012-02-29)
Empirical methods should be applied only in situations where the features are similar to those used in their original database. The Stability Graph methodologies proposed by Mathews et al. (1981) and by Potvin (1988) are ...
La densidad electrónica como campo escalar en la generación de gráficas moleculares
(Universidad Autónoma Metropolitana (México). Unidad Azcapotzalco. División de Ciencias Básicas e Ingeniería., 2015)
Se implementó el método de González-Schlegel para la generación de gráficas moleculares. El método resultó ser un procedimiento robusto y eficiente para este propósito. Se ejemplifica que, con la implementación de este ...
