TThere are several variables that determine in the process of impregnation include the flow of water into the well, the value of shape factors and in situ field permeability.This research aim is to investigate the shape factor of flat base recharge wells values of the three models whose upper walls are made of concrete buis with diameters of 0.6 m, 0.8 m, and 1.0 m.The high porous wall with var iations: 0.3 m, 0.7 m and 1.0 m. The shape factor is the coefficient of dimension planning which takes into accou nt the perimeter and area of the recharge well, volume and water level. The Permeability coefficient is very important. Experiments in the field are three recharges well models in a flat base impregnation on the porous wall (L) test and well radius (R The value of permeability of soil obtained by direct drilling of the research area in Sukolilo Village, Malang Indonesia. Field permeability was obtained by using auger boring falling Head method with a soil depth of 00.0 m to 2.65 m.he result showed that shap e fa ctor simultaneously influenced the high of porous wall (F = 23.71 > F table = 5.32; P < 0.05). However, the positive correlation between the changes of shape factor and high of porous wall in flat base on the recharge wells (R2 = 0.88)
The kernel estimator especially the univariate type often needs one smoothing parameter as against more smoothing parameters demanded by greater dimensional estimators though it all depends on kind of smoothing parameterizations employed. The smoothing parameter(s) of kernels with higher dimension may be called smoothing matrices. Kernels of higher dimensions have three kinds of parameterizations as estimators viz: constant, diagonal and full parameterizations. Unlike the full parameterization, the diagonal parameterization exhibits some levels of restrictions. This study investigates the efficiency of kernel estimators to which smoothing parameterizations are applied. The asymptotic mean-integrated squared error is employed as a criterion function with emphasis on bivariate case only. With real data, the results show that full smoothing parameterization outperformed the constant and diagonal parameterizations in respect of the asymptotic mean-integrated squared error’s value and the kernel estimate’s ability to retain the true characteristics of the affected distribution
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%
In this paper an effort is made to documentation of the design of microwave sensor with frequency falls in the range of UWB spectrum which it is using for non-invasive blood glucose concentration. It is very simple and cost-effective self-monitoring continuous blood glucose measurement system. A relationship between the changes in blood permittivity and the frequency response is observed. This can lead to a measuring procedure in which the glucose level present has a correlation with value of response frequency of sensor. The proposed system includes a microwave resonator which places on the patient's arm. Then, the initial frequency resonance of the sensor modifies because of the changes resulted in the measuring of the dielectric permittivity of blood, and changes in the value of the frequency shifted of the sensor
