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 ... -
Apología de la vaca esférica: modelos sencillos para sistemas complejos
El éxito de la Ciencia de la Complejidad se debe, fundamentalmente, a su capacidad de explicar comportamientos emergentes y universales a partir de modelos relativamente sencillos. Por contra, en áreas afines como la ... -
Model the path: impact of propagation models on the scalability analysis of a wireless M-Bus sensoring system for smart grids
This paper analyses the impact of the propagation model on the outcomes of a scalability analysis of a wireless M-Bus system simulated in OMNeT%2B%2B. Four path loss models are compared: Free Space Path Loss (FSPL) model ... -
Impact assessment of FCUC on optimal design of UFLS settings in Island Power Systems
A frequency constrained unit commitment (FCUC) formulates the non-linear, non-convex frequency dynamics to obtain the generation dispatch of island power systems (IPSs). Even with FCUC, under frequency load shedding (UFLS) ... -
Evaluating the impact of required cooling expenditure on households’ energy burden: The Spanish case study
Adequately meeting space cooling needs has traditionally been considered a luxury in the Spanish residential sector. However, this trend is changing, concurrently with the increase in reversible heat pumps’ installation, ...
