Mathematical Modeling of Fixed-Bed Columns Adsorption: Hexavalent Chromium onto Chitosan Flakes
(American Chemical Society (ACS), 2020-08)
Continuous fixed-bed column adsorption for wastewater treatment provides the most practical application to reduce water pollution by heavy metal ions. The objective of this work was to develop a new statistical approach ...
A general overview of formal languages for individual-based modelling of ecosystems
(Elsevier BV, 2019-04-01)
Various formal languages have been proposed in the literature for the individual-based modelling of ecological systems. These languages differ in their treatment of time and space. Each modelling language offers a distinct ...
A progressive damage based lattice model for dynamic fracture of composite materials
(Elsevier, 2020-11)
In this paper we present an extension of the linear elastic lattice model for anisotropic materials previously developed by the authors. This approach takes into consideration damage evolution in composite materials by ...
Comparison between the Operational and Statistical Daily Maximum and Minimum Temperature Forecasts in The Central Coast of Peru
(American Meteorological Society, 2023-02)
Multiple linear regression models were developed for 1-3-day lead forecasts of maximum and minimum temperature for two locations in the city of Lima, in the central coast of Peru (12°S), and contrasted with the operational ...
A storm-time global electron density reconstruction model in three-dimensions based on artificial neural networks
(Elsevier, 2024-02-16)
We present results of a dedicated global storm-time model for the reconstruction of ionospheric electron density in three-dimensions. Using the storm criterion of |Dst| ≥ 50 nT and Kp ≥ 4, the model is constructed using a ...
Micromechanical modeling of particle reinforced polymers
(IMPRENTA UNIV ANTIOQUIA, 2010-08-01)
This work describes an easy to use constitutive model able to predict the mechanical behavior of polymer matrix particulate composites at temperatures above the glass transition temperature Tg. This model was basedon both ...
Finding the simplest mechanistic kinetic model describing the homogeneous catalytic hydrogenation of avermectin to ivermectin
(American Chemical Society, 2011-04)
Six mechanistic kinetic models of increasing complexity are analyzed to describe the RhCl(Ph3P)3 catalyzed hydrogenation process to produce ivermectin from avermectins B1a and B1b. Global sensitivity analysis (GSA) usefulness ...
Automatic generation of ETL processes from conceptual models
(11/06/2009)
Data warehouses (DW) integrate different data sources in order to give a multidimensional view of them to the decision-maker. To this aim, the ETL (Extraction, Transformation and Load) processes are responsible for extracting ...
Modelling ETL processes of data warehouses with UML activity diagrams
(11/09/2008)
Extraction-transformation-loading (ETL) processes play an important role in a data warehouse (DW) architecture because they are responsible of integrating data from heterogeneous data sources into the DW repository. ...
