Predicting Performance of Hall Effect Ion Source Using Machine Learning
This study introduces HallNN, a machine learning tool for predicting Hall effect ion source performance using a neural network ensemble trained on data generated from numerical simulations. HallNN provides faster and more accurate predictions than numerical methods and traditional scaling laws, making it valuable for designing and optimizing Hall ...

A memristor‐based associative learning circuit is presented for real‐time, fault‐tolerant sensor fusion in autonomous systems. The circuit mimics biological learning to recognize driving scenarios even with missing or degraded sensor inputs. Its low‐power, analog architecture enables robust decision‐making across diverse conditions, offering a ...

Civic engagement among adolescents: Spanish adaptation and validation of the civic engagement scale
Abstract The aim of this research was to adapt and validate the Civic Engagement Scale (CES) developed by Doolittle & Faul for the Spanish adolescent population while providing empirical support for its psychometric properties. After administering the instruments to 965 adolescents from high schools, confirmatory factor analyses were conducted to ...
