    Performance of Hyperparameters in Prediction with Deep Neural Networks of Electrical Properties of Nano-Coated Glasses Nano-Kaplamali Camlarin Elektriksel zelliklerinin Derin Sinir Aglari Ile Tahmininde Hiper Parametrelerin Performansi

    Nano-coated glasses are widely used in different fields such as industry, transportation and architectural structures. After these glasses are obtained by various thin film coating applications, they are subjected to the heat treatment process (tempering, bending, etc.), which is considered as a secondary process. Both of these two-stage processes lead to changes in the electrical and mechanical properties of the final product. While electrical properties such as transmittance, coated surface reflection and uncoated surface reflection values obtained as a result of the first stage can be calculated by analytical methods; the chaotic nature of the second stage does not allow these parameters to be calculated with similar methods. Therefore, in this study, a multi-input-multi-output deep neural network structure was designed for the estimation of the electrical properties of the nano-coated glass type produced for commercial use in architectural fields. Moreover, The dataset with 64 different coating types was augmented by adding noise technique and the performances of the hyperparameters in prediction success were compared. The performance of the network structure was measured by the mean absolute error, mean squared error, and coefficient of determination metrics. The designed network structure was tested on 16 samples and according to the results obtained, it was observed that the best performance was achieved with the Adadelta learning algorithm and ReLU activation function on the augmented data set.

    A novel monitoring dashboard and hardware implementation simplifying the remote access in industry
    (2023-07-18) KORKMAZ, HAYRİYE; Korkmaz H., Demir E.
    In today’s world where technology is developing with a great speed, it is getting harder day by day to adapt or include changes on new technology to the processes in facilities. Insisting on using conventional solutions adopted so far in industrial facilities cause problems to compensate the changing fast consumption needs of today. Adopting recent technologies improves the maintenance and troubleshooting processes of the facilities, accelerates the production and increases the quality of production. In this way, technology based smart systems can provide the devices or machines with the skills required for problem solving and system development in the industry. In this study, a remote monitoring and control application is proposed for a frequency inverter which is widely used and critical device for motor driving in industrial facilities is discussed and a novel internet of things (IoT) based communication gateway is developed. In this way, it is intended to improve the problem solving skills of field personnel by contributing with remote support.
