Re-synchronisation of a microgrid to the main grid using multi-agent secondary control
The idea of having self-powered microgrids has often been proposed to take full advantage of distributed generation resources. These microgrids can work either isolated from or connected to the main grid, which brings a ... -
State relevance and modal analysis in electrical microgrids with 100 grid-forming converters
In traditional power systems, dominated by syn-chronous generators, the separation between time scales is well-known due to the physical response of the generating units. However, the fast-growing deployment of renewable ... -
Capex temporal allocation and cost recovery in long-term generation capacity expansion planning
This work revisits some interesting properties of long-term generation models and sheds light on cost-recovery properties associated to this kind of representations in the framework of marginalist remuneration electricity ... -
Probability density-based energy-saving recommendations for household refrigerating appliances
The power sector is a major contributor to anthropogenic global warming, responsible for 38 of total energy-related carbon dioxide emissions and 66 of carbon dioxide emission growth in 2018. In OECD member countries, the ... -
Analyzing mobility patterns of complex chronic patients using wearable activity trackers: a machine learning approach
This study suggests using wearable activity trackers to identify mobility patterns in Chronic Complex Patients (CCP) and investigate their relation with the Barthel Index (BI) for assessing functional decline. CCP are ... -
“Sólo es humor”. Sexismo, homofobia y violencia online en la conformación del género y la sexualidad en los adolescentes
La ponencia presenta los resultados de parte de la investigación realizada para el proyecto europeo Horizonte 2020 RAYUELA sobre cibercrimen y menores, analizados desde una perspectiva de género. A partir de los datos ... -
Género, sexualidad y online grooming: diferencias en las estrategias de los agresores y en la percepción del riesgo de las víctimas
La ponencia presenta los resultados de una parte de la investigación realizada para el proyecto europeo Horizon 2020 RAYUELA sobre cibercrimen y menores. En concreto, los hallazgos sobre el online grooming analizados desde ... -
Design and sensitivity analysis of underfrequency load-shedding schemes of isolated power systems based on frequency stability margin
The objective of this paper is to tune the parameters of an underfrequency load shedding (UFLS) scheme based on the frequency stability margin (FSM) and compare its performance with the conventional UFLS scheme. The ... -
A two-stage approach to represent the daily LNG carriers unloading in natural gas optimization models
Natural gas is expected to play a key role in the energy system of the next decade since it is one of the mainstays of global energy and can still replace more polluting fuels. At the same time, many countries’ dependence ... -
The effectiveness of cervical airbags in the control of head and neck kinematics
Cyclists represent a significant percentage of seriously or fatally injured road users. Head and brain injuries in cyclists have been extensively studied, but less focus has been given to cervical injuries. Airbags are ... -
Characterisation of the features of seat‐belt systems based on the analysis of large crash databases
The goal of this study was to develop a method to analyse the seat?belt force?time history measurements obtained from laboratory crash tests to characterise the b pre?tensioner and load?limiting features. The study also ... -
A Machine Learning approach for the validation and optimization of permittivity mixing rules for binary liquids
This paper presents the application of Support Vector Regressor models trained with glycerin-water mixture signals from a Dielectric Resonator sensor. Each signal is labeled with a concentration considered. The performance ... -
Nueva regulación del control de tensión: desafíos para las centrales nucleares españolas
A lo largo de los últimos veinticinco años el sistema eléctrico peninsular español ha conocido una transformación sin precedentes debido a la penetración de las fuentes de energía renovables alcanzada. Uno de los desafíos ... -
Design & manufacturing of dielectric resonators via 3D printing
Background: In recent years, the research of new materials and manufacturing methods for telecommunication and sensing applications has received significant attention. The demand for novel and high-performance dielectric ... -
Analyzing traffic conflicts and the behavior of motorcyclists at unsignalized three-legged and four-legged intersections in Cartagena, Colombia
Introduction The global motorcycle market has grown significantly, with over 770 million vehicles estimated to be in use worldwide. Motorcycle-related road traffic deaths in low and middle-income countries (LMICs) like ... -
The effect of seatbelt pre-tensioners and load limiters in the reduction of MAIS 2%2B, MAIS 3%2B, and fatal injuries in real-world frontal crashes
Contemporary research has pointed out that while newer cars are contributing to the decrease of AIS2%2B and AIS3%2B injuries in several body regions, this effect is not shown for thoracic injuries like rib or sternal ...
