    Non-Contact Vibration Detection Software and Hardware Design with Image Processing Method to Reveal Substantial Changes in Structures and Systems
    (Kırıkkale Üniversitesi, 2020) Metin, Emre; Karagülle, Özgür; Kayalak, Abdullah; Karagülle, Mustafa; Çam, Ertuğrul
    Many types of equipment are used for vibration detection in buildings and systems. However, these systems have their own problems. In this article, a combined software and hardware system is designed for the solution of these problems. The system has been designed with the Motion Magnification Analysis (MMA) method, which stands out in the literature studies. C # language and .NET environment have been used as software. The Accord library was used for the image processing process. These libraries were also used for the analysis of subspaces and components of the image. During the study, three new algorithms that have not been applied in the past and not in the literature have been developed. The first of these is the derivative of the method known as Color Magnification, which analyzes the color space. The second is the derivative of the Motion Magnification method, which magnifies the vibration to the visible level. And the third one is the Frequency Determination algorithm, which enables frequency measurement. With this solution, it is provided to make an analysis of the images taken with devices with relatively slow cameras such as mobile phones/tablets as well as fast cameras. All results were compared with a touchable vibration analyzer for benchmarking and showed that the proposed method was successful.

    The Importance of Energy Quality in Medical Devices and Evaluation of Measurements Made in Kırıkkale University Medical Faculty MRI Device within the Scope of TS EN 50160
    (Kırıkkale Üniversitesi, 2020) Metin, Emre; Karagülle, Özgür; Kamışlı, Kardelen; Çam, Ertuğrul
    Today, the increase in demand for electrical energy has revealed a more reliable and higher quality energy concept. This subject has taken its place in electrical engineering as "Power Quality" or "Electric Energy Quality" and has made a point for its importance with the studies on it. Especially in the process of working with devices containing electronic circuits with direct current and using the alternating current offered from the network by using rectifiers, the devices may fail or become disabled due to self-protection circuits in case of power quality problems arising from the mains or the rectifiers of the device. In this article, a detailed analysis is carried out considering the problem may be due to the power quality due to the fact that the MRI device in Kırıkkale University Faculty of Medicine is in continuous failure mode. In addition, the analyzes made in accordance with TS EN 50160 standard within the scope of the research were analyzed in computer environment and the results were shared in our article. In this article, the relationship between power quality problems and grounding is also examined.
