Total Cost of Ownership of Electric Vehicles: A Synthesis of Critical Factors

open access: yesThe Journal of Engineering, Volume 2025, Issue 1, January/December 2025.
This study uses a systematic review to evaluate the total cost of ownership (TCO) as a tool for assessing electric vehicle (EV) feasibility compared to internal combustion engine vehicles. Findings highlight that while EVs have higher upfront costs, supportive policies and lower operating expenses can enhance their competitiveness.

Risk Mapping for Daily High‐Speed Railway Disturbances Based on Operation Loss

open access: yesJournal of Advanced Transportation, Volume 2025, Issue 1, 2025.
Confronted with the disturbances arising from various risk events, it is crucial to accurately measure the severity of risks in the dispatching section for efficient train operation and transportation management of a high‐speed railway (HSR). This paper proposes a risk mapping method for daily HSR disturbances based on a self‐formulated operation loss ...

Existence of solutions for hybrid fractional pantograph equations

open access: yesApplicable Analysis and Discrete Mathematics, 2015
In this paper, we study the existence of the hybrid fractional pantograph equation {D?0+[x(t)/f(t,x(t),x(?t))= g(t,x(t), x(?t)), 0 < t < 1, x(0) = 0, where ?,?,? ?((0,1) and D?0+ denotes the Riemann-Liouville fractional derivative. The results are obtained using the technique of measures of noncompactness in the Banach algebras and a ...

Analytical Approximate Solutions for a General Class of Nonlinear Delay Differential Equations

open access: yesThe Scientific World Journal, 2014
We use the polynomial least squares method (PLSM), which allows us to compute analytical approximate polynomial solutions for a very general class of strongly nonlinear delay differential equations. The method is tested by computing approximate solutions
