PEMFC state and parameter estimation through a high-gain based adaptive observer
(2020)
Article
Open AccessThis work presents the design of an adaptive observer to estimate the cathode catalytic layer's water content of a polymer electrolyte membrane fuel cell and some of the parameters related to its water dynamics. However, ... -
Ontological concepts for information sharing in cloud robotics
(Springer, 2020-06-10)
Article
Open AccessRecent research and developments in cloud robotics (CR) require appropriate knowledge representation to ensure interoperable data, information, and knowledge sharing within cloud infrastructures. As an important branch of ... -
Active power sharing and frequency regulation in droop-free control for islanded microgrids under electrical and communication failures
(Institute of Electrical and Electronics Engineers (IEEE), 2020-08-01)
Article
Open AccessThe droop-free control for ac microgrids achieves active power sharing and frequency regulation by replacing the centralized secondary control and the primary-level droop mechanism by a cooperative distributed control ... -
Fuzzy control system design for wheel slip prevention and tracking of desired speed profile in electric trains
(2020-01-01)
Article
Restricted access - publisher's policyThis study proposes an anti-slip control system for electric trains based on the fuzzy logic theory, which prevents the wheels from slipping during the acceleration and simultaneously tracks the desired speed profile. To ... -
A Hysteresis dynamic mathematical model approach to parametric estimation system
(Hindawi, 2021-02-14)
Article
Open AccessThe main contribution of this paper is the proposal of a recent hysteresis dynamic model which is successfully employed within a posited signal modulator. The modulation of signals is a commonly required stage in many ... -
Leak diagnosis in pipelines using a combined artificial neural network approach
(2021-02-01)
Article
Restricted access - publisher's policyLeakages in pipelines affect the reliability of fluid transport systems causing environmental damages, economic losses, and pressure reduction at the delivery points. Therefore, this paper presents a methodology to detect ... -
Design and implementation of a virtual sensor network for smart waste water monitoring
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-01-08)
Article
Open AccessA high density virtual sensor network has been designed to robotize sampling tasks associated with monitoring of water treatment plant with open air basins. The designed virtual network is to be actually implemented by a ... -
A randomised kinodynamic planner for closed-chain robotic systems
(Institute of Electrical and Electronics Engineers (IEEE), 2021-02-01)
Article
Open AccessKinodynamic rapidly-exploring random tree (RRT) planners are effective tools for finding feasible trajectories in many classes of robotic systems. However, they are hard to apply to systems with closed-kinematic chains, ... -
Wind turbine main bearing fault prognosis based solely on SCADA data
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-03-23)
Article
Open AccessAs stated by the European Academy of Wind Energy (EAWE), the wind industry has identified main bearing failures as a critical issue in terms of increasing wind turbine reliability and availability. This is owing to major ... -
Adaptive predictive control for peripheral equipment management to enhance energy efficiency in smart manufacturing systems
(2021)
Article
Restricted access - publisher's policyThe importance of implementing energy efficiency methodologies in industrial environments has increased considerably in the last decade given the high energy costs and environmental impact (e.g., greenhouse gas emissions). ... -
Atypical lymphoid cells circulating in blood in COVID-19 infection: morphology, immunophenotype and prognosis value
(2020-01-01)
Article
Open AccessAims Atypical lymphocytes circulating in blood have been reported in COVID-19 patients. This study aims to (1) analyse if patients with reactive lymphocytes (COVID-19 RL) show clinical or biological characteristics related ... -
Computer algebra tales on Goppa codes and McEliece cryptography
(2020-06)
Article
Open AccessThe 40-year old McEliece public-key crypto-system is revisited with the help of recently developed resources: an improved Peterson–Gorenstein–Zierler decoder for alternant error-correcting codes; PYECC, a purely Python ...
