This study bridges neuroscience and artificial intelligence by developing advanced models to predict cognitive states—specifically attention meditation—using raw EEG data collected from low-cost commercial devices such as NeuroSky Brainlink. Leveraging the temporal capabilities of recurrent neural networks (RNNs), particularly long short-term memory (LSTM) gated units (GRUs), evaluates their effectiveness in predicting future states. These predictions have applications real-time...

Aqueous Organic Redox Flow Batteries (AORFBs) have received much attention due to the accessibility of their active materials. However, among key performance indicators that require improvement for AORFBs become competitive against mature technologies, lifespan is especially critical stationary energy storage. Faradaic imbalance driven by occurrence irreversible electrochemical processes decreases lifespan, so monitoring and correction this parameter required prolong lifespan. This work...

Many current parallel computers are built around a torus interconnection network. Machines from Cray, HP, and IBM, among others, make use of this topology. In terms topological advantages, square (2D) or cubic (3D) tori would be the topologies choice. However, for different practical reasons, 2D 3D with number nodes per dimension have been used. These mixed-radix not edge symmetric, which translates into poor performance due to an unbalanced network resources. work, we analyze twisted that...

Anaerobic membrane bioreactors have become an environmentally friendly solution for wastewater treatment. The lack of sufficiently accurate mathematical procedures to model their behaviour and the fouling process membranes, poses a challenge when trying optimise energy consumption maintenance costs. An membranes is critical make most this technology. This perfect scenario in which introduce neural networks (NN) as alternative modelling. However, duration experiments difficulties measuring...

Neurodegenerative diseases present significant challenges in terms of mobility and autonomy for patients. In the current context technological advances, brain–computer interfaces (BCIs) emerge as a promising tool to improve quality life these Therefore, this study, we explore feasibility using low-cost commercial EEG headsets, such Neurosky Brainlink, control robotic arms integrated into autonomous wheelchairs. These headbands, which offer attention meditation values, have been adapted...

The response surface methodology has been applied to study reversible and irreversible fouling rates caused by anaerobic sludge in membrane bioreactors, with the aim of controlling adjusting filtration conditions. challenge obtaining statistically significant results long-term means mid-term assays addressed. individual combined effects flux, backwashing intensity, gas sparging crossflow velocity on fouling, were analyzed two types membranes: an external tubular a submerged hollow fiber...

Many parallel computers use Tori interconnection networks. Machines from Cray, HP and IBM, among others, exploit these topologies. In order to maintain full network symmetry, 2D 3D must have the same number of nodes (k) per dimension resulting in square or cubic Nevertheless, for practical reasons, computer engineers designed built having a different dimension. These mixed-radix topologies are not edge-symmetric which translates into poor performance provoked by an unbalanced links. this...

Abstract Anaerobic digestion allows efficient treatment of high loaded wastewater, and membrane technology obtaining quality effluents with complete biomass retention. However, concentration interferes fouling. In the present work, a new bioreactor that integrates an attached anaerobic culture on fixed bed submerged has been started up. The recirculation between filtration chambers is coupled to gas-lift effect bubbling employed for scouring membranes, avoiding use or electromechanical pumps...

Abstract A new membrane technique is described for the extraction of low molecular weight organic compounds from a wide range substrates. With this system, interest contained in sample pass through toward solvent, while other substances higher are excluded by membrane. This procedure allows or elimination toxic with yield 90%.

Abstract Aqueous Organic Redox Flow Batteries are a family of promising energy storage systems. However, they face various challenges related to their lifetime, such as the Faradaic imbalance due occurrence parasitic reaction leading fading its capacity. Herein, automatization rebalancing system reverse detrimental effects unavoidable presence small quantities oxygen in negative reservoir or hydrogen evolution is developed and implemented an alkaline flow battery. A membrane‐free cell...

All technical degrees in the Spanish Higher Educational System include a mandatory Final or Honours project. This is activity which should lead student to put into practice most of skills acquired throughout whole degree. Only are usually practice, although recent studies have proved that further capabilities, such as those included category “social skills”, will also be demanded by employers. Moreover, introduction European System, strongly emphasizes importance this sort capabilities. What...
