This study discusses tools for digital current monitoring using an Arduino-based ACS712 sensor. The current sensor ACS712 5A uses the principle of hall effect and is a current sensor whose circuit complexity is simple. The purpose of this microcontroller is to read data obtained from the sensor using the Analog to Digital Converter (ADC) feature and then display it in the serial monitor. The ATMEGA328 microcontroller is assisted by a current measuring circuit equipped with a sensor mounted in series against the circuit to be measured in order to measure the current flowing in the circuit. The test results show that the sensor can measure the current value at its peak value with an error value of -0.066 and a standard deviation value of 0.011419. Based on the test results it can be seen that the tool can work well and has a good accuracy rate.

Today, the high usage of electrical home appliances has increased the domestic energy consumption. To control the consumption of domestic energy, various techniques were developed to detect current flow and to measure current consumption. Usually, a current sensor was used as a detection device and then send the data wirelessly to a centre point in the house, which is placed near to the main entrance for monitoring and controlling purposes. Wireless technology can provide better connection and reducing the need for wired connection for all power sockets in a house. The usage of LCD is to display current usage for all electrical home appliances will be more useful especially for a multi-storey house. This smart current monitoring system, will help users to monitor and control their electrical home appliances current consumption. The system will monitor each power sockets and transmit the current usage data wirelessly to a centre point which helps in reducing the time to check all the appliances.

Abstract Lock-in IR-OBIRCH analysis, as a kind of static thermal laser stimulation (S-TLS) technique, is very effective to isolate a fault for the parametric failure cases. However, its capability is limited to localize a defect when the IC is operated under a defined operating condition. Whereas the dynamic thermal laser stimulation (D-TLS) technique is good at locating a fault while the IC is operated under some functions to activate the failure. In this paper, a novel method is presented to realize DTLS just by Lock-in IR-OBIRCH assisted with a Current Detection Probe Head. Two cases are studied to demonstrate the effectiveness of this method.

The Equivalent Turn Number of Coil (ETNC) is proposed for induction coil design. Simulation results show that the vibrationonthe induction coil’s structure. The optimized coil is composed by two symmetry parts on the condition of sinusoidal vibration. The effective value of output EMF of optimized coil increases 51.39% than uniform coil’s. In the experiment, the optimized and uniform coils are fabricated with 600 turns and comparatively studied in the same vibration-to-electrical generator. The test results show that the peak-to-peak value and effective value of output EMF of the optimized coil can increase up to 52.59% and 48.76%, respectively, compared with the uniform coil.

One of the communication technologies that can be used for monitoring current usage is communication technology via electric grids or what is called Power Line Communication (PLC). The advantages of this technology are that the electricity network is already distributed in each building so there is no need for new installations, it is economical and affordable in terms of economics, and is more practical and flexible in its use. In this study, a current usage monitoring system using PLC is proposed which will be applied in every class in the AI ??building of Malang State Polytechnic. The sensor that will be used in measuring the current value is the current sensor SCT-013. By using the KQ330 PLC module as a PLC transmission modem. The implementation of PLC which is applied in each class in the AI ??building has a BER (bit error rate) value of 0.012 in the experiment of sending 1000 data with an error of 12 times at the farthest distance of approximately 15 meters. And have a BER value of 0 or have no error in sending data at the closest distance of approximately 2-5 meters. In this study, the process of sending and receiving data using Power Line Communication allows it to be done at a distance that is not too far away to avoid excessive data errors.

Tests of bird strike have been carried out on plate made from LY-12 Aluminium. The test was down with the projectile impacting the target perpendicularly at velocity of 40m/s, 80m/s, 120m/s respectively. The displacement-time history curves and strain-time history curves of on LY-12 Aluminium plate were measured. The good agreement of the results between two specimens in one group indicated that the results tested in the presnet paper are reliable. The dynamic response of the plate and damage modes of the bird influenced by striking velocity were analyzed. The peak value of the displacement linear enlarged with the increasing of the striking velocity. The test results in the present paper provided valuable data for aircraft design impacted by bird, and also provided abundant test datas for the numerical simulation model applied in bird striking.

A novel moving bed biofilm reactor has been developed, where the biofilm grows on small, free floating plastic elements with a large surface area and a density slightly less than 1.0 g/cm3. The specific biofilm surface area can be regulated as required, up to a maximum of approximately 400 m2/m3. The ability to remove organic matter from concentrated industrial effluents was tested in an aerobic pilot-plant with two moving bed biofilm reactors in series and a specific biofilm surface area of 276 m2/m3. Treating dairy wastewater, the pilot-plant showed 85% and 60% COD removal at volumetric organic loading rates of 500 g COD/m3h and 900 g COD/m3h respectively. Based on the test results, the moving bed biofilm reactors should be very suitable for treatment of food industry effluents.
