Analysis of Smartphone Triaxial Accelerometry for Monitoring Sleep-Disordered Breathing and Sleep Position at Home
(Institute of Electrical and Electronics Engineers (IEEE), 2020-04-13)
Article
Open AccessObstructive sleep apnea (OSA) is a sleep disorder in which repetitive upper airway obstructive events occur during sleep. These events can induce hypoxia, which is a risk factor for multiple cardiovascular and cerebrovascular ... -
Enabling grid-feeding converters with a dissonant-resonant controller for negative-sequence voltage elimination
(Institute of Electrical and Electronics Engineers (IEEE), 2020-04-01)
Article
Open AccessThe mitigation of the adverse effects of voltage unbalance in equipment and power quality can be performed by the power electronic converters that interface distributed generators to the grid. Inspired in a resonant ... -
Fusing hotel ratings and reviews with hesitant terms and consensus measures
(2020-02-27)
Article
Restricted access - publisher's policyPeople have come to refer to reviews for valuable information on products before making a purchase. Digesting relevant opinions regarding a product by reading all the reviews is challenging. An automated methodology which ... -
Dynamic modelling of alkaline self-pressurized electrolyzers: a phenomenological-based semiphysical approach
(2020-01-01)
Article
Restricted access - publisher's policyThis paper proposes a phenomenological based semiphysical model (PBSM) for a self-pressurized alkaline electrolyzer. The model, based on mass and energy balances, represents the dynamic behaviour of hydrogen and oxygen ... -
Control-oriented modelling and analysis of a solid oxide fuel cell system
(2020)
Article
Restricted access - publisher's policyIn this paper, a control-oriented model of a solid oxide fuel cell system is formulated and analyzed in detail. First, a lumped model based on first principle laws is formulated and tuned using experimental data coming ... -
Optimal tuning of the control parameters of an inverter-based microgrid using the methodology of design of experiments
(2020-10-01)
Article
Open AccessThe design of the control system in an inverter-based microgrid is a challenging problem due to the large number of parameters involved. Different optimisation methods based on obtaining an approximated mathematical model ... -
Robust repetitive control of power inverters for standalone operation in DG systems
(2020-03-01)
Article
Open AccessStandalone operation of an inverted-based distributed generation unit is performed in voltage control mode. In this mode, it is important that the controller provides tracking and rejection of periodic signals. Strategies ... -
Bridging cognitive models and recommender systems

Robust economic model predictive control based on a zonotope and local feedback controller for energy dispatch in smart-grids considering demand uncertainty
(2020-02-01)
Article
Open AccessElectrical smart grids are complex MIMO systems whose operation can be noticeably affected by the presence of uncertainties such as load demand uncertainty. In this paper, based on a restricted representation of the demand ... -
A simple switching frequency regulated sliding mode controller for a VSI with a full digital implementation
(Institute of Electrical and Electronics Engineers (IEEE), 2020-01-06)
Article
Open AccessThis paper describes the design of a first order sliding mode controller for a VSI operating at fixed switching frequency. The proposal is simple, as it does not include any integral or resonant action in the switching ... -
Negative-sequence voltage elimination for distributed generators in grid-feeding operation mode
(2020-07-24)
Article
Restricted access - publisher's policyA major concern of the power quality in distributed systems is related to the mitigation of voltage imbalances. This function can be implemented directly in the control system of the distributed generation power converters ... -
Identifying muscle synergies from reaching and grasping movements in rats
(Institute of Electrical and Electronics Engineers (IEEE), 2020-01-01)
Article
Open AccessReaching and grasping (R&G) is a skilled voluntary movement which is critical for animals. In this work, we aim to identify muscle synergy patterns from R&G movements in rats and show how these patterns can be used to ...
