A novel strategy to guarantee a minimum indoor temperature in social housing buildings
(ELSEVIER, 2023-10)Energy poverty, along with climate change, is becoming one of the most worrying issues in Europe. Many people live without a minimum thermal comfort in their homes because they are not able to afford high energy bills. In ... -
A Study of Learning Issues in Feedforward Neural Networks
(MDPI, 2022-09-05)When training a feedforward stochastic gradient descendent trained neural network, there is a possibility of not learning a batch of patterns correctly that causes the network to fail in the predictions in the areas adjacent ... -
A Theoretical Study of the Hydrodynamic Performance of an Asymmetric Fixed-Detached OWC Device
(MDPI, 2021-09-25)The chamber configuration of an asymmetric, fixed-detached Oscillating Water Column (OWC) device was investigated theoretically to analyze its effects on hydrodynamic performance. Two-dimensional linear wave theory was ... -
Accounting for homeowners? decisions to insulate: A discrete choice model approach in Spain
(Elsevier, 2022-10)This paper assesses Spanish households' willingness to thermally insulate their homes and the drivers that influence such a decision-making process. Stated preference data were collected through a discrete choice experiment ... -
Active flow control on airfoils by reinforcement learning
(Elsevier, 2023-11-05)Active flow control is a widespread practice for airfoil aerodynamic performance enhancement. Within active flow control, reactive strategies are very effective, but the adequate design of these strategies is often complex. ... -
