Railway Auxiliary Power Supply System: A Modular Multilevel Converter Approach
Transportation Research Procedia, 2023 When it comes to power railway systems, two main aspects must be considered: (i) the power of the propulsion of the train, which is responsible for the movement of the train; (ii) the power of the auxiliary services, which is responsible for the power inside the train for commodity and service of the passengers.

Scalar auxiliary variable approache for the surface quasi-geostrophic equation
Journal of Algorithms & Computational Technology, 2023 We present a numerical method for approximating the two-dimensional surface quasi-geostrophic equation. We first reformulate the equation into an equivalent system by using the scalar auxiliary variable approach.
