    Automated image processing system design for engineering education: The case of automatic inspection for printed circuit boards
    (American Society for Engineering Education, 2015) Tuncalp B.K.; Taskin S.; Turgut Y.
    An experimental test-bed in engineering education enhances the quality of studies and provides industrial experiences to engineer candidates. The purpose of this paper is to develop a multi-purpose test-bed for detecting defects (faults) on printed circuit boards (PCBs). Specifically, the test-bed utilizes the techniques from image processing. To achieve this aim, first a visual pattern inspection system was designed for PCBs, and second an algorithm was developed for detecting the defects related to PCB traces. The system addresses four main aspects: (i) the automatic inspection; (ii) independent angle of rotation; (iii) displaying the PCB defect area; and (iv) creating a database for defect history. Based on the results derived from several defect tests, our findings show that the system can be adapted with ease for basic industrial applications as well as a training test-bed for engineering courses such as digital image processing. © 2015 American Society for Engineering Education.

    Designing a real-time remote control system for undergraduate engineering and engineering technology students
    (American Society for Engineering Education, 2016) Yabanova I.; Taskin S.; Ekiz H.; Oǧuz Y.; Akaslan D.; Yumurtaci M.
    This paper explains the design of a control system intended to enhance the quality of education in engineering and engineering technology departments and considers the use of various concepts: remote-access, real-time, reconfigurable properties, and multi-user controls. Controlling the system's hardware is possible by using fuzzy logic and PID control methods to teach several engineering concepts in the field of automatic control (i.e., DC motor and temperature control). PID parameters and fuzzy logic membership rules can be modified by authorizing remote users. A Web interface was also designed as part of the system to create an opportunity for the end-users to observe real-time changes in DC motor and temperature control. Modifications to the control system's parameters also enable users to record output to their own personal computers via the Internet; this allows users from other engineering institutions to access and modify the PID and fuzzy logic membership rules for more experiences. In this way, various theoretical and practical concepts associated with the field of automatic control can be implemented without any limitations. The overall findings from this study indicate that engineering and engineering technology curricula in any institution can effectively be delivered using the Internet to overcome the limitations of distance, as remote-access experiments are becoming highly applicable anywhere and anytime.
