Thermoelectric Energy Conversion in a Lid-Driven Cavity Microgenerator Using Nanofluids

Nanomaterials
The present research seeks to characterize and evaluate a lid-driven cavity–TEG system to harness residual energy. Therefore, the behavior of water and a nanofluid (SiO2) in a rectangular lid-driven cavity is numerically studied.

Mathematical modeling and fuzzy proportional–integral–derivative scheme to control the yaw motion of a wind turbine

Wind Energy, 2021
In this paper, we present a mathematical model and control strategy to regulate the yaw of a horizontal axis wind turbine. In order to obtain the dynamic equations of the yaw motion, the mathematical model is developed using the Euler–Lagrange ...

Tuning the Sensitivity of Photonic Sensors Toward Alkanes Through the Textural Properties of Hybrid Xerogel Coatings

Advanced Functional Materials, Volume 35, Issue 3, January 15, 2025.
A propylsilane molar content of just 5% makes a poor‐responding silica xerogel film to become sensitive toward non‐aromatic, large volatile organic compounds with low or null polarity when assembled into a photonic sensor with reflection architecture. This device is particularly suitable to detect cyclohexane, with large signal variation, fast kinetics,

Aggregated Demand Flexibility Prediction of Residential Thermostatically Controlled Loads and Participation in Electricity Balance Markets

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
The aggregate demand flexibility of a set of residential thermostatically controlled loads (TCLs) can be represented by a virtual battery (VB) in order to manage their participation in the electricity markets. For this purpose, it is necessary to know in advance and with a high level of reliability the maximum power that can be supplied by the ...

Comparative analysis of RNN versus IIR digital filtering to optimize resilience to dynamic perturbations in pH sensing for vertical farming

Agrosystems, Geosciences &Environment, Volume 7, Issue 4, December 2024.
Abstract Vertical farming (VF) refers to systems of agriculture where crops are grown in trays stacked vertically by exposing them to artificial light and using sensing technology to improve product quality and yield. In this work, we propose an advanced filtering scheme based on recurrent neural networks (RNNs) and deep learning to enable efficient ...

Improved protection for colour images via invertible colour‐to‐grey, image distortion, and visible‐imperceptible watermarking

IET Image Processing, Volume 18, Issue 13, Page 3854-3863, 13 November 2024.
An invertible colour‐to‐grey algorithm is presented. The approach protects both the colour and structure of the colour image against illegal usage and distribution. Abstract Invertible colour‐to‐grey algorithms protect the colour of an image against illegal usage and distribution.
