A comprehensive method for the elastic calculation of the two-point wheel-rail contact
(Taylor & Francis, 2006)This work shows the method developed to solve the wheel-rail contact problem via a look-up table with a three-dimensional elastic model. This method enables introduction of the two contact point effect on vehicle movement ... -
A comprehensive review of C-S-H empirical and computational models, their applications, and practical aspects
(Elsevier, 2022-06)[EN] The C-S-H gel is an elusive material. Its variable composition and disordered nature complicate a complete characterization of its atomic structure, and the elaboration of models is key to understanding it. This work ... -
A comprehensive review of primary strategies for tar removal in biomass gasification
(Elsevier, 2023-01)In the current energy scenario, the production of heat, power and biofuels from biomass has become of major interest. Amongst diverse thermochemical routes, gasification has stood out as a key technology for the large-scale ... -
A comprehensive review of the impact of transmission technologies on the electrical grid
(Imprenta Universidad de Antioquia, 2019-05-17)The electrical infrastructure needs the integration of communication technologies, and in recent decades the progress has been significant. Therefore, this work presents the latest advances in this subject, as well as new ... -
A comprehensive study of the phase segregation of a urea-based phase change material tested under thermal cycling conditions
(Elsevier, 2023-04)Eutectic mixtures are used as PCMs due to the possibility to tailor the melting temperatures and mainly because the phase transition occurs at a unique temperature. Eutectic mixtures are assumed to be congruent melting and ... -
A Comprehensive Study of Vesicular and Non-Vesicular miRNAs from a Volume of Cerebrospinal Fluid Compatible with Clinical Practice
(Ivyspring International Publisher, 2019)Cerebrospinal fluid (CSF) microRNAs (miRNAs) have emerged as potential biomarkers for minimally invasive diagnosis of central nervous system malignancies. However, despite significant advances in recent years, this field ... -
A Computational Analysis of Protein-Protein Interaction Networks in Neurodegenerative Diseases
(Biomed Central, 2008-06-20)Background: Recent developments have meant that network theory is making an important contribution to the topological study of biological networks, such as protein-protein interaction (PPI) networks. The identification of ... -
A Computational Module Assembled from Different Protease Family Motifs Identifies PI PLC from Bacillus cereus as a Putative Prolyl Peptidase with a Serine Protease Scaffold
(Public Library Science, 2013-08)Proteolytic enzymes have evolved several mechanisms to cleave peptide bonds. These distinct types have been systematically categorized in the MEROPS database. While a BLAST search on these proteases identifies homologous ... -
