Resonance-Based Procedure for Locating Failed Luminaires in AGL Systems
(Institute of Electrical and Electronics Engineers (IEEE), 2017-08)
Aeronautical ground lighting (AGL) systems provide a visual reference for aircraft during airport operations. Fast detection and location of failed luminaires is an important safety concern in AGL systems. In the event of ...
Effect of wind turbine converter control on wind power plant harmonic response and resonances
(The Institution of Engineering and Technology, 2017-02)
Wind turbine harmonic emissions due to power electronics are a well-known power quality concern in wind power plants (WPPs). This problem may be increased by resonances because they amplify harmonic distortion around ...
Positive-Net-Damping Stability Criterion in Grid-Connected VSC Systems
(Institute of Electrical and Electronics Engineers (IEEE), 2017-05)
Resonance instabilities in power systems can be assessed with the positive-net-damping stability criterion. This criterion is a review of the complex torque coefficients method but it does not provide the frequency of the ...
Arquitecturas interactivas. Prácticas visuales emergentes en la ciudad interfaz
(Universidad Politécnica de Valencia, 2019)
We are living the transition from
a static to a dynamic architecture
driven by the integration of new
technologies into the urban
environment. In this scenario,
citizens abandon their passive
roles in order to ...
Study of Resonances in 1X25 kV AC Traction Systems With External Balancing Equipment
(IEEE, 2016-10)
AC traction systems are 1 × 25 or 2 × 25 kV/50 Hz single-phase, nonlinear, time-varying loads that can cause power-quality problems, such as unbalanced or distorted voltages. To reduce unbalance, external balancing equipment ...
Bioactive zinc-doped sol-gel coating modulates protein adsorption patterns and in vitro cell responses
(Elsevier, 2020-12-30)
Zinc is an essential element with an important role in stimulating the osteogenesis and mineralization and suppressing osteoclast differentiation. In this study, new bioactive ZnCl2-doped sol-gel materials were designed ...
Optimal sampling pattern for free final time linear quadratic regulator: the scalar case
(Taylor & Francis, 2020-12-28)
The optimal sampling problem is the selection of the optimal sampling instants
together with the optimal control actions such that a given cost function is minimized.
In this article we solve the optimal sampling problem ...
Metodología para el desarrollo de modelos de simulación ejecutables para sistemas de fabricación
(Open Journal Systems (OJS) / PKP, 2021-03-15)
In recent years, the adoption of the principles of Model Based Systems Engineering (MBSE) in the context of manufacturing systems has promoted the development of highly complex (hybrid simulations, multi-scale, multi-domain, ...
Study on Different Graphic Representations in Architectural Heritage: Digital and Physical Modelling
(IGI Global, 2018-07)
In recent years, cutting-edge methods have emerged to gradually replace or be used with traditional
methods to carry out graphic surveys of architectural heritage; modern topographic tools such as 3D
scanners and specific ...
Harmonic Resonance Stability of Aeronautical Ground Lighting Systems
(IEEE, 2018-02)
Aeronautical ground lighting (AGL) systems assist aircraft pilots in airport operations. These systems are singlephase series circuits where constant current regulators (CCRs) feed luminaires with an adjustable rms current. ...
