In this paper, the soil resistivity has been measured in the vicinity of a power station which situated near Brunei Liquefied Natural Gas (BLNG) of the Belait District. According to IEEE 81-1983 standard, the soil resistivity of this substation is measured using the equipment Fluke 1625. The measured soil resistivity data are then used into the CYME GRD software to calculate the soil resistivity and is found to be 63.8 ohm-m. Rectangular grid with the dimension of 50 m by 32 m is considered for the simulation of ground resistance, ground potential rise, touch and step potentials based on the IEEE 80-2000 standard. The simulation result of ground resistance, ground potential rise, tolerable touch and step potentials are found to be 0.66 ohm, 11061.2 V, 1171.3 V, 4193.10 V respectively. The simulation results are then compared with the calculation results using MATLAB GUI and are found in good agreement.

Nowadays, Not only the accuracy of a classification system but also a feature extraction method is an important matter in a Brain Computer Interface Application. In this paper, we investigated the multiclass classification of mental task using EEG signal. Higuchi Fractal Dimension and 10-Statistic Parameters were used as feature extraction method. The 10-statistic parameters are central tendency type that is, maximum value, minimum value, mean, standard deviation, median, mode, variance, first-quartile, third-quartile, interchange quartile. Multiclass Support Vector Machine with One-against-All strategy is applied to classify EEG signal related to the mental task. The result shows that the Multiclass SVM classifier with 1-against-All strategy using 10-Statistic Parameters has a higher accuracy when compared to Higuchi Fractal Dimension-SVM, Extreme Learning Machine, Back Propagation Neural Network, both of Support Vector Machine 1-versus-1 strategy and 1-versus-All strategy. The average accuracy ranging between 99.2% and 100% for 10-Statistic Parameters-SVM and HFD_SVM ranging from 60.22% to 91.91% were gained for five mental task classes.

In order to analyze the impulse characteristics of substation grounding grids correctly, a grounding grids model is designed and custom-made based on a 35kV substation grounding grids. The impulse characteristics of grounding grids are studied through simulating corrosion, breakage and sealing-off. Meanwhile, the impact of different impulse points and lightning impulse are also analyzed. The result shows that, with the same current injection point, the impulse grounding resistance rises with the front time of lightning impulse declines. With the same lightning current, when the lightning impulse is injected through the corner of grounding grids, the impulse grounding resistance is bigger than that when the lightning impulse is injected through the center of grounding grids. If the grounding grids has fault, the impulse grounding resistance will increase, but the growing rate has close relation with fault type and lightning current. The study may provide a basis for grounding grids design and evaluation.

An ultrathin normally-off lattice matched In0.17Al0.83N/GaN metal oxide semiconductor high electron mobility transistor is proposed. Analytical model for two-dimensional electron gas density has been developed to investigate the critical thickness of InAlN barrier. Numerical simulations have been performed using SILVACO TCAD to justify that the critical barrier thickness is 8nm for inducing the two-dimensional electron gas. A sub-critical 3nm thick barrier device is simulated and a positive threshold voltage of 1V is realized at 10nm oxide (Al2O3) thickness. The transconductance and drain characteristics are also studied in order to verify the feasibility of the device. The proposed device can overcome the lacuna of enhancement mode GaN based devices in power electronic applications.

The 8 mobile service bands MIMO antenna that consists of both a monopole + IF A antenna and an auxiliary slot antenna on the metal cover is designed and implemented. Two antennas which are laid up and bottom side of the PC board are diagonally fed for the MIMO system. Auxiliary slot locates on the rear metal cover, and handles for LTE class 40 band. The S11 of antenna satisfies under -6dB (VSWR 3: 1) for L TE class 131 L TE class 141 CDMAI GSMI DCSI PCSI W-CDMAI LTE class 40 bands. ECC value for MIMO characteristic is less than 0.2 over the entire design bands. Average gains and antenna efficiencies measured in the anechoic chamber were -5.57~-1.45 dBi and 27.75~71.6 %, respectively.

The Philippines is one of the rising economies in Southeast Asia. However, it is facing a power crisis where there is a continuous increases in an already huge demand in electricity given the limited and scare supply from different power sectors. Consumers are called to be aware of their power consumption and make necessary efforts towards the smart and efficient use of it. As a response, the proponents developed an appliance-level system that monitors and analyzes power consumption. The monitoring subsystem was implemented through a portable hardware black box which includes the power meter sensor, an Arduino microcontroller clone board and a ZigBee shield for wireless transmission to a microcomputer. The Raspberry Pi microcomputer served as a temporary local server for the sync node and the gateway for the data to be stored in an online database. From this, the analysis subsystem retrieves the consolidated data to undergo both retrospective and Winter's forecasting technique. All necessary information, figures and graphs will be presented to the user for interpretation through a simple web application. Overall, the study fulfills its vision of giving people the power over their utility bills by being a tool for raising awareness towards responsibly reducing power consumption to a more efficient use.

In this paper, we propose a parallel fixed-width multiplier design that receive two n-bit numbers and produce a n-bit product. To design the proposed fixed-width multiplier, three multiplication modules are used that can work as independent smaller-precision multiplications. In order to add the outputs of the multiplication modules, carry save adder and Brent-Kung adder is used which can further improve the performance of the design. Implementation results demonstrate that the proposed fixed-width multiplier with parallel multiplication modules achieve significant improvement in delay and power-delay product when compared with previous architectures.

This paper presents a battery module capacity monitoring system with a high voltage (HV) current sensor and a calibrated current estimation approach (CCEA) method. Battery modules usually are utilized to generate HV and large currents to drive motors of electric vehicle (EV). The battery modules are controlled and monitored by a system to protect the modules from possible hazards, e.g., battery management systems (BMS). However, since the BMS needs to deal with HV signals, it is very difficult to be implemented using logic integrated circuits (ICs). The proposed design, by contrast, is implemented using a typical 0.25 μm 1P3M 60V BCD process and field programmable gate array (FPGA) to resolve this issue. The sensing current range of the proposed system is 0.44 A ~ 2.2 A, while the voltage is from 36 V to 55 V. The worst-case deviation of the capacity estimation is 8.6 %.

Synthetic aperture (SA) imaging algorithm, which combines sub-aperture elements to form high resolution image, can improve image quality in vivo ultrasound image. However, large computation resource is generally required for the implementation of SA. In this paper, we propose a parallel structural design for SA imaging algorithm that can be realized in Field Programmable Gate Array (FPGA), so that light weight and miniaturized design can be achieved. The proposed design has been validated by MATLAB and was employed to construct a high resolution ultrasound imaging from the raw data of 128 array transducer elements. The processing time is about 2.6ms theoretically, which should be alright for usage.

This paper presents a method based on V-Q sensitivity and modal analysis to study the transient voltage stability of receiving AC network with HVDC feeding. When faults of receiving network occur, HVDC recovery characteristics are analyzed, which have an important effect on voltage stability of receiving network. The model of active power and reactive power time series responding to the recovery characteristics is built for simplicity, which is applied to replace HVDC systems for transient simulation. Based on simulating results, at each of time frames, Q-V sensitivity and modal analysis can be utilized, and the moment when the reactive power consumed by the HVDC systems rising to high values is the main concern to investigate voltage stability. Bus participation factors are calculated by modal analysis and weak voltage area is found out. Finally, a multi-infeed HVDC test system is studied to verify the feasibility of the method.
