Preliminary Characterization of Chromium (VI) Solution Adsorption with Mytella charruana in Semi-Artificial Environments
The bivalve specie Mytella charruana has shown great potential as a bioindicator in natural waters and a biofilter for the adsorption of metals, such as Cr(VI). This species has been found in important densities in Cartagena ...
Spatio-Temporal Filtering for Evoked Potentials Detection
We propose the new application of the spatio-temporal filtering (STF) method, which is a detection of visual evoked potentials applied to brain-computer interfaces (BCI). STF aims in creating a new, enhanced channel basing ...
Implementation of an E.R.P. Inventory Module in a Small Colombian Metalworking Company
This paper aims to analyze the effect of implementing an inventory module of ERP Openbravo for the reduction of information flow time and customer response time, in a Colombian metalworking company. The processes structure ...
Modeling and control of a small hydro-power plant for a DC microgrid
(Elsevier Ltd, 2020)
This paper presents the modeling and control of a small hydro-power plant (SHP) for a DC microgrid based on passivity theory. The SHP is made up of a turbine, a permanent magnet synchronous generator (PMSG), a voltage ...
Relaxed convex model for optimal location and sizing of DGs in DC grids using sequential quadratic programming and random hyperplane approaches
(Elsevier Ltd, 2020)
This report addresses the problem of optimal location and sizing of constant power sources (distributed generators (DGs)) in direct current (DC) networks for improving network performance in terms of voltage profiles and ...

SIDS-DDoS, a Smart Intrusion Detection System for Distributed Denial of Service Attacks
In the last few years, the Digital Services industry has grown tremendously, offering numerous services through the Internet and using a recent concept or business model called cloud computing. For this reason, new threats ...
Standard passivity-based control for multi-hydro-turbine governing systems with surge tank
(Elsevier Inc., 2020)
This paper addresses the problem of control design for hydro-turbine governing systems with surge tanks from the perspective of standard passivity-based control. The dynamic model of a synchronous machine is considered in ...
A model for the simulation of the chill block melt spinning (CBMS) process using OpenFOAM®
(Elsevier Masson SAS, 2020)
This work shows the results of a numerical model developed to simulate the CBMS technique for the production of the Fe78Si9B13 metallic magnetic ribbons for application in electronics. The model proposes a numerical ...
