Testing and simulation of swelling behaviour of Lithium-Ion batteries based on preload conditions.

- Grey box-based equivalent circuit modelling of Lithium Ion and Supercapacitor to capture the dynamics of the cell and to study further the grid-forming setup of a Hybrid Energy Storage System (HESS). - Study different battery technologies and create a parameterisation framework based on recyclability, suitability, readiness level, and modelling approach as part of an EU-based project.

Computed Modelling, drafting, technical planning and project management of “Cobot”, a robot that can be used in manufacturing industries for assembly automation, using AutoCAD and Fusion 360

Increasing the aerodynamic efficiency of the wing by adding features below the wing flap. The feature tends to increase the lift force and reduce the drag force of the wing, to be used in subsonic planes and drones. Simulation of the wing by varying the alpha, beta and angle of attack and measuring the parameters: coefficient of drag, coefficient of lift, drag force and lift force. Finding the conditions which produce the maximum efficiency.
