Numerical Investigation of Rainfall Infiltration-Induced Slope Stability Considering Water-Air Two-Phase Flow
For insights into rainfall infiltration on soil slopes and coupled transmission mechanisms, two-phase flow and finite element analysis were employed to examine water and air movement during the Shuping landslide. The results indicated a division of the landslide surface into two zones: an upper inflow area and a lower overflow area, driven by contrasting inflow and outflow directions. The total water and air flux remained stable, minimally affected by external factors such as rainfall attributes, surface runoff, and air temperature variations. In the inflow area of the slope surface, when rainfall intensity was greater than the total rate of the infiltration of water and air, the magnitude of infiltration equalled to the total rate infiltration of water and air, and runoff generation occurred in this area. Conversely, when infiltration matched rainfall intensity, runoff was absent in this area. In addition, water pressure in the saturated area of the slope surface can be transferred to the groundwater of the slope by pore air pressure, which could also increase the pressure head of the groundwater, and this was also detrimental to slope stability. Regarding uniform rainfall, it significantly reduces the safety factor, potentially making it the most hazardous pattern for slope failure.

E-Textiles to Promote Interdisciplinary Education
Electronic textiles (e-textiles) is a current research and development direction of the textile domain. As final applications, e-textiles may monitor human vital signs for sports and medicine, may extend garment functionality for entertainment, or ensure electromagnetic compatibility (EMC) using flexible textile shields. However, this book chapter focuses on a certain aspect of e-textiles, namely, their role in promoting interdisciplinary education. E-textile products are the result of material science, physics, mathematics, mechanics, electronics, and more recently of software and Artificial Intelligence (AI). This was the rationale for initiating three Erasmus+ projects in the field of e-textiles to foster interdisciplinary training for students and young professionals. The new educational materials tackle the relation between Science Technology Engineering Mathematics (STEM) disciplines of the official curricula and some of their final applications, such as e-textile prototypes. The educational materials are conceived in a problem-based learning (PBL) approach. The presented examples encompass fabrics with inserted metallic yarns and metallic coating for electromagnetic interference (EMI) shielding, pressure sensors, and related electronic data processing, as well as virtual prototyping of Radio frequency (RF) suits. EMC is tackled from an educational perspective.
