Evaluation of the impact of cluster formation in a direct reduction shaft furnace through numerical simulation

open access: yesREM: International Engineering Journal, 2021
The Direct Reduction (DR) process has been growing worldwide, and there are strong context suggestions that it will grow even more. One of these factors is the environmental pressure that occurs worldwide, and there are already projects to migrate Blast ...

A Blind Nonlinearity Compensator Using DBSCAN Clustering for Coherent Optical Transmission Systems

open access: yesApplied Sciences, 2019
Coherent fiber-optic communication systems are limited by the Kerr-induced nonlinearity. Benchmark optical and digital nonlinearity compensation techniques are typically complex and tackle deterministic-induced nonlinearities.

Correlation of Climate Variability and Burned Area in Borneo using Clustering Methods

open access: yesForest and Society, 2020
The island of Borneo has faced seasonal forest fires for decades. This phenomenon is worsening during dry seasons, especially when droughts are concurrent with the El Niño-Southern Oscillation (ENSO) phenomenon. Climate is therefore one of the drivers of

Word Sense Clustering and Clusterability [PDF]

open access: yesComputational Linguistics, 2016
Word sense disambiguation and the related field of automated word sense induction traditionally assume that the occurrences of a lemma can be partitioned into senses. But this seems to be a much easier task for some lemmas than others. Our work builds on recent work that proposes describing word meaning in a graded fashion rather than through a strict

Adaptive Evolutionary Clustering

open access: yes, 2011
In many practical applications of clustering, the objects to be clustered evolve over time, and a clustering result is desired at each time step. In such applications, evolutionary clustering typically outperforms traditional static clustering by ...

Providing Customised Information Panel Content Based on User Behavioral Patterns

open access: yesMendel, 2018
Although mobile applications are commonly using user location and behavior to provide relevant content, public information panels usually lack the ability to adjust the content for a particular user or a group of users.

Factor PD-Clustering

open access: yes, 2012
Factorial clustering methods have been developed in recent years thanks to the improving of computational power. These methods perform a linear transformation of data and a clustering on transformed data optimizing a common criterion.
