After the COVID-19 epidemic, which emerged in December 2019 and is still in effect, almost all countries had to implement strict measures to control the spread of the virus. The ability of experts to reduce the spread primarily depends on the determination of the criteria affecting the spread. The fact many criteria that affect the rate of spread of COVID-19 and the most effective criteria cannot be determined, causes the spread, and therefore the number of positive cases and deaths to increase. Therefore, in the study;firstly, the weights of the criteria affecting the rate of spread were determined by using the full consistency method (FUCOM), which is a multi-criteria decision-making method, and the criteria that most affected the spread were determined by Pareto analysis, based on the criteria weights obtained. Then, based on the criteria obtained, the number of confirmed cases was predicted using the random forest method. The performance criteria values of the random forest were compared with different artificial intelligence methods such as artificial neural network, decision tree and support vector machine. Random forest gave the best results with error values (RMSE (3247), MAE (1714) and RRSE (0.374)). In addition, the random forest achieved a high prediction success of 92.9%.

In this study, it is aimed to increase shielding effectiveness of electromagnetic shields by coating with graphene sheet. Firstly, graphene monolayer is modeled numerically and it is observed that it is in good agreement with the analytical findings. Then, the reflection loss of bilayer screen that is formed by coating the back surface of an aluminum plate with graphene sheet, is analyzed analytically and numerically. Finally, a shielding enclosure in which inner surfaces are coated with graphene sheet is modeled and the change of shielding effectiveness of the shielding enclosure with respect to the chemical potential and temperature values of graphene sheet is investigated. It is obtained that shielding effectiveness of shielding enclosure decays depending on the increase of chemical potential of graphene sheet while the temperature parameter remains fixed. Shielding effectiveness values are obtained close to each other at the temperature 300 K and above depending on the increase of temperature of graphene sheet while the chemical potential remains fixed.
