Fusing convolutional generative adversarial encoders for 3D printer fault detection with only normal condition signals
(Elsevier, 2021)
Collecting data from mechanical systems in abnormal conditions is expensive and time consuming. Consequently, fault detection approaches based on classical supervised learning working with both normal and abnormal data ...

Reachability problems in low-dimensional iterative maps
(World Scientific, 2008)
In this paper we analyse the dynamics of one-dimensional piecewise maps (PAMs). We show that one-dimensional PAMs are equiv- alent to pseudo-billiard or so called \strange billiard" systems. We also show that the more ...

Improving Skip-Gram based Graph Embeddings via Centrality-Weighted Sampling
(Cornell University, 2019)
Network embedding techniques inspired by word2vec represent an e ective unsuper- vised relational learning model. Commonly, by means of a Skip-Gram procedure, these techniques learn low dimensional vector representations ...

Generative Adversarial Networks Selection Approach for Extremely Imbalanced Fault Diagnosis of Reciprocating Machinery
(IEEE Computer Society, 2019)
At present, countless approaches to fault diagnosis in reciprocating machines have been proposed, all considering that the available machinery dataset is in equal proportions for all conditions. However, when the application ...

Computationally Hard Problems Addressed Through P Systems
(Springer, 2006)
In this chapter we present a general framework to provide efficient solutions to decision problems through families of cell-like membrane systems constructed in a semi-uniform way (associating with each instance of the ...

Real-time gun detection in CCTV: An open problem
(Elsevier, 2020-12)
Object detectors have improved in recent years, obtaining better results and faster inference time. However, small object detection is still a problem that has not yet a definitive solution. The autonomous weapons detection ...

Una metodología desde la teoría de redes para las redes culturales
(Pontificia Universidad Javeriana, 2020)
Este documento presenta, desde un punto de vista introductorio y orientado a no expertos en teoría de redes, los fundamentos de grafos y redes que permiten proyectar información sobre redes culturales en un contexto formal. ...

The Potosí principle: religious prosociality fosters selforganization of larger commnities under extreme natural and economic conditions
(Oxford Academic, 2012)
We show how in colonial Potosı´ (present-day Bolivia) social and political stabil-ity was achieved through the self-organization of society through the repetition of religious rituals. Our analysis shows that the population ...

A Virtual Laboratory for the Study of History and Cultural Dynamics
(JASSS, 2011)
This article presents a Virtual Laboratory that enables the researcher to try hypothesis and confirm data analysis about different historical processes and cultural dynamics. This Virtual Cultural Laboratory (VCL) is ...

Institutions and Cultural Diversity: Effects of Democratic and Propaganda Processes on Local Convergence and Global Diversity
(Public Library of Science, 2016)
In a connected world where people influence each other, what can cause a globalized monoculture, and which measures help to preserve the coexistence of cultures? Previous research has shown that factors such as homophily, ...
