A stochastic 3D modeling approach for the nanoporous binder-conductive additive phase in hierarchically structured cathodes of lithium-ion batteries is presented. The binder-conductive additive phase of these electrodes consists of carbon black, polyvinylidene difluoride binder and graphite particles. For its stochastic 3D modeling, a three-step procedure based on methods from stochastic geomet…
In the automotive industry, the absorption coefficient of a porous material layer is usually measured in an alpha cabin, a reverberant chamber of reduced dimensions where the operational frequency range is limited and the absorbent sample size is typically small. Those characteristics are well adapted to the requirements of automotive acoustics but far from the standard reverberant chambers use…
The implementation of thermally sprayed components in steel manufacturing presents challenges for production and plant maintenance. While enhancing performance through specialized surface properties, these components may encounter difficulties in meeting modified requirements due to standardization in the refurbishment process. This article proposes updating the established coating process for …
Viscoelastic fluids have several applications in industry and technology, which has attracted a lot of investigation into their mathematical models. This paper presents the first-ever verifiable convergent second-order method, with complete theoretical analysis, for one-dimensional viscoelastic flow model. Existing studies have focused on first-order methods and without theoretical analysis. He…
Achieving both high quality and cost-efficiency are two critical yet often conflicting objectives in manufacturing and maintenance processes. Quality standards vary depending on the specific application, while cost-effectiveness remains a constant priority. These competing objectives lead to multi-objective optimization problems, where algorithms are employed to identify Pareto-optimal solution…
Health promotion strategies in early childhood are needed to address the global problem of physical inactivity. In Hong Kong, where the movement guidelines recommended by the World Health Organization for young children have been adopted by the health authorities, we implemented evidence-informed dissemination strategies targeting teachers and parents in kindergarten settings. Workshops, resour…
The current study examines teacher deployment strategies in Cambodian preschools and identifies challenges related to the supply and deployment of teaching staff in early childhood education by assessing the adequacy, efficiency, and quality of teacher deployment. This study employs multiple approaches in data collection, including desk review of existing policies and literature, analysis of sc…
Access to equitable, quality, and inclusive early childhood education (ECE) has positive effects on school readiness, transition, and overall development and learning in all children. This paper seeks to explore barriers and facilitators to the implementation of learning through play (LtP) for preschoolers in Kenya with a view to enhance collaboration between parents and teachers. The curren…
This study evaluates a professional development (PD) initiative that used an innovative quality improvement methodology, the Breakthrough Series Collaborative (BSC), in early childhood education and care (ECEC) settings in the United States. We examined: (1) the extent to which programs engaged with the activities of the initiative, (2) whether the hypothesized mechanisms by which the initiativ…
Users of technology are becoming younger over the years. Although the current generation of young children is often referred to as “digital natives,” this designation primarily reflects their intuitive engagement with digital tools rather than a comprehensive understanding of their responsible use. In contrast, fostering balanced, ethical, and safe digital behavior requires intentional educ…
