Going with the flow to solve for symmetry-driven PDE dynamics with physics-informed neural networks

We address a computational framework that integrates symmetry reduction into Physics-Informed Neural Networks (PINNs) for analysing symmetry-driven dynamics in nonlinear partial differential equations (PDEs). Using an auxiliary network to learn time-dependent transformations, we...

Sustainability Certifications in Building Projects: Adoption Insights from the Greek Construction Sector in the European Context

Sustainability certification schemes (SCSs) such as LEED, BREEAM, etc., are widely accepted as an effective tool for the promotion of sustainable design principles and lifecycle carbon reduction in building projects. Greece, despite having a relatively small real estate market, p...

Advancing Sustainable Metallurgy Through an Electrified Indirect Heated Rotary Kiln: Efficient Magnesite Calcination and Hydrogen-Based Reduction of Lateritic Ores

The transition towards climate-neutral metallurgical production requires a broader transformation than the simple substitution of fossil-fuel combustion with electrical heating. While process electrification is a fundamental step towards reducing greenhouse gas emissions, achievi...
