EEG-Based Detection of Induced Relaxation

Bunyarat Umsura, Wanus Srimaharaj, Phakkharawat Sittiprapaporn et al. · 2025 · IEEE Access

Relaxation, which refers to the absence of tension and stress, is important for health because extended periods of tension may lead to illness. This study detected induced relaxation through electroencephalography (EEG) for the real-time monitoring of brain activity. The Multivariate Empirical Mode Decomposition with Dynamic Phase-Synchronized Hilbert-Huang Transform (MEMD-DPS-HHT) algorithm was utilized to extract dynamic brain wave patterns from the EEG data of participants exposed to the blended essential oils. Preprocessing included artifact removal using independent component analysis (IC

Solar energy for liquid wastewater treatment with novel TiO2 supported catalysts

Rui C. Martins, Ângelo Sacras, Sanja Jovanovic et al. · 2022 · Energy Reports

Photocatalytic oxidation is promising technology for removal of recalcitrant pollutants from water. Solar energy can be an interesting radiation source since the operating costs can be lower. However, the use of powder photocatalyst is a major drawback of the technology since suitable separation technologies are required and catalysts recovery is difficult. This work aims to test the suitability of using polymeric supports to immobilize TiO 2 in the reactor and apply it for parabens removal from water by solar photocatalytic oxidation. Polyurethanes (PU) and polydimethylsiloxane (PDMS) membran

Raw material depletion and scenario assessment in European Union – A circular economy approach

Florinda F. Martins, Hélio Castro · 2020 · Energy Reports

Nowadays the production systems are linear and the consumption patterns are essentially based on products with a short life cycle, which contribute to increase the demand for raw materials and environmental impacts. The Circular Economy (CE) is playing a major role among scholars and practitioners. Many aspects are now defining this new trending paradigm such as the roles of product development, transformation and remanufacturing/recycling, and/or management of waste, ensuring the economic and environmental benefits. The increasing demand causes instability of the prices and markets, and there
