“…The voltage would be strengthened by an analog signal conditioning circuit (amplifier) to be processed by the microcontroller. The results would be displayed on an Android mobile phone [23], [24] via a Bluetooth module [25]- [27] as the sender and receiver of data. In addition, Android phones could also control X-ray exposure time measurement device such as resetting readings or measurements.…”

The purpose of this study was to design an X-ray microcontroller-based ATmega328P microcontroller exposure time measurement device. That can be done by integrating an X-ray detection circuit, analog signal conditioner, ATmega328P microcontroller and Bluetooth module HC-05 to display and control the measurement results on mobile phones Android. The benefits of this research are expected to be able to increase knowledge and expertise in the field of radiology instruments through X-ray machine parameter measurement techniques and assist technicians to calibrate the X-ray exposure time parameters.

“…DC (direct current) motor is used in many applications and nearly most mechanical movement that can be observed around us. As it is found in several domestic appliances such as HD cameras, smart toys, mixing machines, and in advanced orthopedic bone drilling [47][48][49][50][51]. Recently, the analysis of the non-linear characteristic of an electric DC motor has become an emerging research topic.…”

Chaotic phenomena are observed in several practical and scientific fields; however, the chaos is harmful to systems as they can lead them to be unstable. Consequently, the purpose of this study is to analyze the bifurcation of permanent magnet direct current (PMDC) motor and develop a controller that can suppress chaotic behavior resulted from parameter variation such as the loading effect. The nonlinear behaviors of PMDC motors were investigated by time-domain waveform, phase portrait, and Floquet theory. By varying the load torque, a period-doubling bifurcation appeared which in turn led to chaotic behavior in the system. So, a fuzzy logic controller and developing the Floquet theory techniques are applied to eliminate the bifurcation and the chaos effects. The controller is used to enhance the performance of the system by getting a faster response without overshoot or oscillation, moreover, tends to reduce the steady-state error while maintaining its stability. The simulation results emphasize that fuzzy control provides better performance than that obtained from the other controller.
