This paper investigates the role of supercapacitor technology in enhancing traction efficiency and reducing infrastructure costs in metro rail systems by replacing conventional track-based electrification. Traditional metro systems rely heavily on continuous electrification through overhead lines or third-rail systems, leading to high capital expenditure, complex infrastructure requirements, and significant energy losses, especially in urban environments with frequent stops. Whereas, the quick charging, adequate regenerative braking, and longevity of supercapictor powered trains enables them preferred choice for local railroad lines.

n this research paper, we have discussed different types of steering geometry such as Ackerman, anti-ackerman and Davis steering geometry. We have also discussed the advantages and disadvantages of all three types of geometry and implemented the best steering geometry for our four-wheel effic-ycle. We have done three iterations to determine the best Ackerman percentage, critical velocity and steering ratio.

The proposed research paper aims to elaborate on a communicative strategy that can enable scripted and unscripted professional interactions. To be impressive, and to offer content that has depth, is to understand professional communication. VASS is a method of communication that I have conceptualised to summarise the heavy factors of creating, memorising and improvising communicative instances in both personal and professional spaces. 

This research paper overviews how a suspension system can be selected, designed and simulated for a four-wheeled vehicle. This research paper discussed the purpose and selection criteria of suspension systems. This study also shows the calculation required under different conditions such as acceleration, braking and cornering. The calculations were further used for Computer-aided engineering (CAE) analysis to determine the total deformation, maximum stress and factor of safety.
