ABSTRACT: 

Recently, driver fatigue is considered worldwide as the main reason of vehicle accidents. However, measuring of the driver fatigue can be directly throughout measuring the driver drowsiness state. This paper is aimed to build a  drowsiness detection system. The system applied consists of two part: pre-recorded EOG signals and application of IR sensor on the eyes blinking. The results revealed a good detection of the eyes blinking based on a biological signal from the sensors. Wearable driver drowsiness detection system is a suitable alternative for reducing vehicle accidents.

Keywords: EOG signal, drowsiness detection system, Wearable driver drowsiness, biological signal, IR sensor.

ABSTRACT: 

The operating temperature of a photovoltaic module significantly impacts its performance and efficiency. The aims of the present study to enhance the performance of a polycrystalline solar cell by decreasing its temperature using a back surface cooling system. For this study, 3D system model is modeled using SolidWorks 2021 software. The cooling system consisted of a layer of phase-change material (RT55 wax) with a thickness of 5 cm and a heatsink consisting of 33 fins of different sizes. A heatsink was added to enhance the thermal conductivity of the paraffin wax. Numerical simulation is carried out with ANSYS FLUENT 2021 R2 software to generate meshing and solve physical problems. The simulation was based on Baghdad's city climate, which included a heat flux of 955 W/m2 and an ambient temperature of 50.1 °C. The predicted results from the numerical simulation showed that the average temperature of the panel before cooling was 65.8 °C, and when wax was applied, the temperature decreased by 8 °C and by 11.9 °C with the addition of the fins (PV-FPC). Also, the output power improved from 190.4 watts to 197.6 Watts and then to 200.6 watts when using the PCM and F-PCM, respectively. Electrical efficiency was 12.93% with PV only. The panel efficiency increased to 13.42% after applying the PV-PCM system and to 13.62% after using the F-PCM system. From this result can be concluded that Combining paraffin wax and fins enhanced efficiency by 3.5%. This result is acceptable and is in good agreement with previous studies.

ABSTRACT: 

Dielectric constants, dielectric degradation, and alternating current conductivity were calculated based on the frequency and composition of the doping material. At higher frequencies, high AC conductivity and a low dielectric constant were observed. The 'Maxwell Wagner Model' can clarify the above hypothesis and may provide new insights into the fabrication of dialectically conceivable nanomaterials. The photocatalytic function of our samples has been investigated by studying the degradation of Rhoda mine B in UV visible light. The photocatalyst analysis provides a convenient way to determine your fate through various reutilizations.
