Removing Omissions and Inconsistencies from the ISA 5.1 Narratives of Industrial Processes
(2020-12-25)
This work is concerned with the modelling of industrial processes, described by Pipe and Instrumentation Diagrams (P&ID) and narratives as specified in the norm ISA 5.1, by Interpreted Petri Nets (IPN). In a previous work, ...
Latencies in power systems: A database-based time-delay compensation for memory controllers
(2021-01-18)
Time-delay is inherent to communications schemes in power systems, and in a closed loop strategy the presence of latencies increases inter-area oscillations and security problems in tie-lines. Recently, Wide Area Measurement ...
Voltage Stability Analysis in Medium-Voltage Distribution Networks Using a Second-Order Cone Approximation
(2020-11-02)
This paper addresses the voltage stability margin calculation in medium-voltage distribution networks in the context of exact mathematical modeling. This margin calculation is performed with a second-order cone (SOCP) ...
A linearized approach for the electric light commercial vehicle routing problem combined with charging station siting and power distribution network assessment
(2021-05-21)
Transportation electrification has demonstrated a significant position on power utilities and logistic companies, in terms of assets operation and management. Under this context, this paper presents the problem of seeking ...
Detection of Sociolinguistic Features in Digital Social Networks for the Detection of Communities
(2020-03-13)
The emergence of digital social networks has transformed society, social groups, and institutions in terms of the communi cation and expression of their opinions. Determining how language variations allow the detection of ...
Libertad y oportunidad. Consideraciones sobre justicia distributiva en Amartya Sen y Philippe Van Parijs.
(2020-08-06)
El presente ensayo tiene como propósito una aproximación a las concepciones de la justicia distributiva en dos economistas contemporáneos: Amartya Sen y Philippe Van Parijs. Para tal fin, se aborda de forma transversal la ...
IMMAN: free software for information theory-based chemometric analysis
(Kluwer Academic Publishers, 2015)
Abstract: The features and theoretical background of a new and free computational program for chemometric analysis denominated IMMAN (acronym for Information theory-based CheMoMetrics ANalysis) are presented. This is ...
On the illumination compensation of retinal images by means of the bidimensional empirical mode decomposition
(SPIE, 2015)
Retinal images are used for diagnostic purposes by ophthalmologists. However, despite controlled conditions in acquisition retinal images often suffer from non-uniform illumination which hinder their clinical use. In this ...
Power flow approximation for DC networks with constant power loads via logarithmic transform of voltage magnitudes
(Elsevier Ltd, 2019)
This paper proposes a logarithmic transformation of voltages (LTVM) for the power flow in DC grids. This problem is non-linear due to the presence of constant power loads (CPLs), which also introduce a negative resistance ...
Programmable diffractive optical elements for extending the depth of focus in ophthalmic optics
(SPIE, 2015)
The depth of focus (DOF) defines the axial range of high lateral resolution in the image space for object position. Optical devices with a traditional lens system typically have a limited DOF. However, there are applications ...
