    Abstract: This research shows a pedagogic experimental and theoretical study of the motion of a simple pendulum, which considers the propotionality to the variables length (L) and period-time (T) of a simple harmonic motion, is presented. The study has used RELU (RECTIFIED LINEAR UNIT) activation function in deep neural network which is a branch of artificia... Show More

    Abstract: Microwave plasma enhanced chemical vapor deposition (MWPECVD) is a cheap and easy method for the modification of materials surfaces to enhance some required property. In this study, benzene as a monomer was deposited on both Aluminum alloy (2024-T3) and glass slide substrates at several pressures and deposition times using MWPECVD. The chemical str... Show More
