Demonstration of sector-coupling based on advanced Thermal Energy Storage: a Model Predictive Control framework for load-shifting and grid-balancing

The roadmap for urban sustainability involves the transition to reliable and decarbonised energy networks. In this regard, business concepts based on sector coupling through the use of Thermal Energy Storage (TES) systems can play a key role. This research is placed in this context, with the aim of evaluating the flexibility potential of novel TES in order to provide load shifting services to the electricity grid and improve the renewables penetration. The idea involves the modelling of the T...

Research hypothesis generation over scientific knowledge graphs

Generating research hypotheses is a crucial step in scientific investigation that involves the creation of precise, verifiable, and logically valid statements that can be empirically examined. Therefore, many efforts have been made to automate or assist this process through the use of various Artificial Intelligence solutions. However, most existing methods are tailored to very specific domains, particularly within the biomedical field. There have been recent attempts to formalize hypothesis ...

An analytical, finite element and experimental study of single-lap joints bonded with epoxy adhesive

This paper investigates the stress distribution in tensile-loaded single-lap joints made of aluminum and bonded with an epoxy adhesive using analytical modeling, finite element analysis (FEM), and experimental testing. The analytical framework is developed for joints with varying material properties, adherend and adhesive thicknesses, and overlap lengths, assuming a constant joint width and a thin adhesive layer. The analysis is based on elasticity theory and the principle of stationary poten...

Thermal modeling of thin-layer bread via neural networks: Experimental validation in a Sardinian bakery

This paper presents neural network-based methods for modeling the cooling behavior of Sardinian flatbreads, validated through experimental data collected in a Sardinian bakery. Building upon previous research on the drying-cooling dynamics of pane Carasau, which identified the Verma model as one of the most suitable thin-layer models for flatbreads, a data-driven framework is developed to tune the Verma model coefficients. Given the Industry 5.0-oriented operational setting of the bakery, the...

Thermal effects in mechanically induced phase transformations in Co powders

The mechanical processing of Co powders by ball milling is known to induce a phase transformation between the two allotropic forms of Co with hexagonal close-packed and face-centred cubic crystalline structures. The same phase transformation can be also activated and driven by gradual heating or isothermal annealing. For this reason, it is reasonable to expect that temperature plays an important role also during the mechanical processing. In this work, we investigate exactly how temperature a...
