In this work, a 2.8x0.22 μm^2 silicon strip waveguide (n = 3.43 @4.234 μm) on a silica substrate (n = 1.38 @4.234 μm) and a superstrate with n = 1 was designed and evaluated through 2D (i.e., mode analysis), and 3D (i.e., wave propagation) analysis to strengthen the interaction between ...

A fully-parameterized 3D model of thermoelectric generator (TEG)-based energy harvesters is built. With the use of a coupled CFD and heat transfer FEM simulation, the temperature field within the complete system (heat source, TEG, cooler, ambient air) is computed. Especially the ... En savoir plus
Cable crossings can affect the performance and ratings of cables. Cables installed adjacently to other power cables are subject to higher temperatures than the expected ones, due to mutual heating between them. In this work, the thermal behaviour of more than 20 cable crossings (Fig.1) ... En savoir plus
Climate change is a short-term problem which can no longer be ignored and affects everything, from global food security to geopolitics and economics: extreme weather phenomena, falling crops yields, decrease of water availability, sea level rise, extinction of several animal species, are ...

Food sterilization is a thermal industrial process used to give products in airtight food packaging shelf life, stability and safety from a microbiological point of view. The term sterilization mainly includes treatments at high temperatures (greater than 100 °C), even in pressurized ... En savoir plus
The pore water pressure in the vadose zone is controlled by the interaction between the soil and the atmosphere through evaporation and infiltration. These processes are strongly influenced by the soil's hydraulic conductivity and water retention properties (Guida et al., 2023). In this ... En savoir plus
Clayey soils and rocks are often used to secure contaminants, dissolved in the interstitial water, or fluids immiscible with water, because of their hydraulic properties (very low permeability and high water retention capabilities, see e.g. McCartney et al., 2016). However, their hydro ... En savoir plus
The exact moment approach (EMA) is adopted to predict, without any fitting parameters, the plate height curves for polystyrene microparticles of different sizes in micropillar array columns performed by hydrodynamic chromatography. The EMA allows us to decouple the contribution of ... En savoir plus
The intestine, a muscular, tubular organ within the digestive system is responsible for the final stages of food processing. The cyclic material transport generates a shear stress on the intestinal lining known as epithelium. Recently, the application of shear stress on epithelial cells ... En savoir plus
Soil sedimentation and consolidation, whether they are naturally or anthropically driven processes, are closely interconnected. While theoretical models are available to separately describe the behaviour of either ‘fluid’ suspensions or ‘solid’ soil, no well-established unified theory ... En savoir plus
