Summary: Currently, there is strong political support for reducing carbon emissions in the transportation sector globally. Public transport operators are embracing electric buses as a means to decrease greenhouse gas emissions and improve air quality. However, the use of electric buses requires a well-functioning urban charging infrastructure. This study focuses on optimizing the design of such an infrastructure to maximize the passenger capacity of electric buses.

Summary: The study showed that increasing the concentration of shear thickening fluid (STF) in the composite structure can improve anti-impact and energy absorption properties. Additionally, the addition of carbon nanotubes (CNTs) to STF resulted in the preparation of C-STF/Ecoflex, which had impact sensing function and could be used in multifunctional wearable devices with anti-impact properties.

Summary: This paper presents an in-depth analysis of the impact behavior of a lightweight monocoque sandwich composite microbus body under full-frontal crash conditions. The study shows that the front and side intrusion of the bus is substantial, resulting in high injury risks for the occupants. By reinforcing the front panel and adjusting the thickness of the sidewalls, floor, and bottom parts, the crashworthiness of the bus can be significantly improved without adding much weight to the structure.

Summary: An innovative numerical method based on a neural network approach is used to solve inverse problems involving the Dirichlet eigenfrequencies for different partial differential operators in bounded domains filled with solid composite materials. The inhomogeneity of the investigated materials is characterized by a vector that is designed to control the constituent mixture of solid homogeneous materials that compose these materials. Numerical examples that demonstrate the applicability of this methodology are presented.

Summary: The majority of global cities rely on diesel buses for public transport, which has significant negative impacts on the environment and human health. To achieve carbon neutrality, public transport operators are replacing their bus fleets with electric buses (EBs). This paper develops a model that considers external costs and incentives to help operators renew their fleets and reach electrification goals. The model is applied to real-world data from a Singaporean bus operator and suggests that EB subsidies can accelerate electrification, achieving full electrification eight years earlier with a 25% subsidy. Additionally, the study explores the effects of diesel taxes and diesel bus (DB) taxes on EB replacement, finding that a 10% diesel tax is effective but a DB tax does not encourage earlier adoption of EBs.
