Ajay Kumar participated in a modelling and simulation course taught from December 2015 to February 2016 at Hochschule RheinMain - University of Applied Sciences. The course covered developing Simulink models, modelling a water treatment plant, control engineering using Simulink and Arduino, and was taught by Professors Dannenmann, Metzler, and Fries. The certificate verifies Ajay Kumar's participation but does not confer any degree, grade, credit, or verify his identity.
