Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

Power consumption is an essential challenge in medical application devices using WSN, where the patient who carries a battery power system. Thus, an energy-efficient monitoring system that can independently measure the vital signs of the patient is necessary. This study presents an energy-efficient wearable patient monitoring system (WPMS) to monitor the temperature, heart rate, and oxygen level in the blood (SpO2). A low power consumption ZigBee wireless protocol was interfaced with Arduino Pro Mini microcontroller based on Atmega 328P to alert caregivers in real-time during emergency cases when risks are observed in the patient's biomedical signs. A sleep/wake algorithm has been proposed and implemented inside the microcontroller to improve the power consumption of this wearable device. Results show that the power saving of 92.39% was achieved based on sleep/wake algorithm relative to the traditional wearable device (i.e., without sleep/wake algorithm). In addition, the battery life was extended to approximately 15 days relative to the traditional one-day operation. Comparison results disclosed that the WPMS outperform the power consumption of other studies in medical applications. Where the average current consumption of 6.13 mA is obtained based on the sleep/wake scheme. We can be concluded that the proposed system is energy-efficient, real-time monitoring, cost-effective, none-complex, comfortable due to it is dispense of wire connection, and easily implemented
This study aims to experimentally investigate the effect of the trim tab on engine power and resistance related to the speed. A surveillance vessel, MV. Hiu 03, equipped with twin-engine, 2 x 770 HP Volvo TAMD 165P. Maxsurf Software was used to calculate the power and resistance of the vessel with the application of the trim tab. Therefore, the sea trial of MV. Hiu 03 was done to get the data experimentally, where the data were compared to the data without trim tab for the variation engine speed in the range 600 rpm to 2000 rpm with 100 rpm increments. The results using Maxsurf software are found that the application of the trim tab decreases the power engine needed by 8% at speed 13.9 knot and 11% at speed 22 knot. Therefore, the resistance decreases by 4% to 6% by using the trim tab. Based on the vessel’s sea trial data the application of trim tabs at after peak on MV. Hiu 03 gives the increase of vessel’s speed approximately by 23% on lower engine speed and by 11% on higher engine speed. Validating the experimental data, Anova two factor analysis showed that there is enough evidence that the fishing patrol vessel using trim tab faster than without trim tab (12.49 knot) with α = 1%
