Centralized Airflow Control to Reduce Output Power Variation in a Complex OWC Ocean Energy Network
(Wiley-Hindawi, 2020-08-18)
A centralized airflow control scheme for a complex ocean energy network (OEN) is proposed in this paper to reduce the output power variation (OPV). The OEN is an integrated network of multiple oscillating water columns ...
On the Use of Entropy Issues to Evaluate and Control the Transients in Some Epidemic Models
(MDPI, 2020-05-09)
This paper studies the representation of a general epidemic model by means of a first-order differential equation with a time-varying log-normal type coefficient. Then the generalization of the first-order differential ...
On the Entropy of Events under Eventually Global Inflated or Deflated Probability Constraints. Application to the Supervision of Epidemic Models under Vaccination Controls
(MDPI, 2020-02-29)
This paper extends the formulation of the Shannon entropy under probabilistic uncertainties which are basically established in terms or relative errors related to the theoretical nominal set of events. Those uncertainties ...
Use of a Reforming Catalyst for Hydrogen Production in the Carbonization Process of Torrefied Biomass
(MDPI, 2020-11-10)
The utilization of charcoal from woody biomass is an efficient way to reduce CO2 emissions from the metallurgical industry. The main aim of this work is to study the charcoal production process from torrefied biomass. For ...
An SIRS Epidemic Model Supervised by a Control System for Vaccination and Treatment Actions Which Involve First-Order Dynamics and Vaccination of Newborns
(MDPI, 2021-12-23)
This paper analyses an SIRS epidemic model with the vaccination of susceptible individuals and treatment of infectious ones. Both actions are governed by a designed control system whose inputs are the subpopulations of the ...
Metamodels’ Development for High Pressure Die Casting of Aluminum Alloy
(MDPI, 2021-10-31)
Simulation is a very useful tool in the design of the part and process conditions of high-pressure die casting (HPDC), due to the intrinsic complexity of this manufacturing process. Usually, physics-based models solved by ...
Advances in Microtechnology for Improved Cytotoxicity Assessment
(Frontiers Media, 2020-11-20)
In vitro cytotoxicity testing is essential in the pharmaceutical and environmental industry to study the effects of potential harmful compounds for human health. Classical assays present several disadvantages: they are ...
A Rubric to Assess and Improve Technical Writing in Undergraduate Engineering Courses
(MDPI, 2021-03-24)
Although there is consensus in the literature that writing skills are important in STEM (Science, Technology, Engineering, and Mathematics) studies, they are often neglected. However, some efforts have been made to correct ...
Annual Weedy Species of Erigeron in the Northern Iberian Peninsula: a Review
(Universidad Complutense de Madrid, 2021)
A revision of the alien Erigeron species formerly included in Conyza found in the northern Iberian Peninsula is presented. A close examination of numerous specimens collected by the authors as well as voucher specimens ...
Elucidating the role of shape anisotropy infaceted magnetic nanoparticles using biogenicmagnetosomes as a model
(Royal Society of Chemistry, 2020-08-14)
Shape anisotropy is of primary importance to understand the magnetic behavior of nanoparticles, but a rigorous analysis in polyhedral morphologies is missing. In this work, a model based on finite element techniques has ...
