This paper presents the performance of grid-connected inverter when installed in three-phase four-wire distribution system. The inverter is utilized as power converter to inject power. Furthermore, this inverter is also utilized as a shunt active power filter to compensate current unbalance, load current harmonics, and load reactive power demand. It is controlled such a way therefore it draws or supplies fundamental active power from and to grid. The control mechanism is carried out by power balance theory using PI controller. The control system consists of DC voltage regulator, phase-locked loop (PLL), and hysteresis current controller. PI controller is used as DC voltage regulator, which regulates DC-link capacitor voltage to be constant. The performance of this controller is demonstrated through simulation. The results of the simulation show the capability of an inverter to inject power to grid. Particularly for nonlinear load, the current harmonics are compensated effectively.

A new neural network structure for adaptive modeling of dynamic system is presented in this paper. Based on multi-layer perceptron (MLP), the network possesses parameter expansion and external recurrence. Parameter expansion is obtained by using tapped delay lines (TDLs) to the outputs of the hidden layer. This increases the number of parameters between the hidden layer and the output layer. Furthermore, external recurrence is obtained by connecting the output and the input of the network. Proper learning algorithm is derived to accommodate the aforementioned modifications. Afterwards, the network is integrated in an adaptive scheme so that it can model systems with changing property or operating condition. The application in modeling of a water tank system demonstrates the ability of the proposed scheme.

Fingerprint information in a database is very important for indoor localization. A good database can provide good estimation results. Meanwhile, the difficult of providing a good database is the complexity of information recording process. The estimated location of the target can be obtained using the fingerprint information in the database and the observed information. In this paper, the reorganization of fingerprint information in the database is considered. Since the process of recording is complex and time consuming, the solution of this problem is using intersection technique. This technique creates a new information instead of fingerprint information in real recording process. The results shows that the proposed technique has better location estimation compared with the old database since the average error distance is less than the gap between tags (fingerprint locations).

In order to improve numerical performance of grounding computation of horizontal multilayer earths, a new type of complex image method has been presented. A closed form expression of Green's function with arbitrary soil parameters, source/observation position has been derived. The infinite value of coefficients A/B in Green's function has been obtained by derived closed form expression. Though numerical value of A/B can be obtained by symbolic algorithms, GNU multiple precision algorithms provides a more simple and reliable way to solve the linear equations of A/B. Then, multi-resolution complex image (MRCIM) method was presented for improvement on both stability and accuracy in numerical grounding computation of horizontal multilayer soils. MRCIM consists of adaptive sampling, decomposition of sampling space, and automations of complex image method approximation. The formula of numerical error by MRCIM has been derived. The validity of MRCIM has been proved by comparative cases. Numerical results show that, during the earth surface potential (ESP) calculation for HVDC transmission earth-return current, DC grounding electrodes can be treated as a current point when observation point is away from over 10 times of dimension of electrodes.

As an increasing of load demand, scarcity of fossil fuel and green house effect, utilization of renewable energy resources such as solar and wind energy are done seriously. The problem rises when potency of them is far smaller than load demand and the high difference between wind velocity profile and solar radiant intensity and load profile is happened. Its make excess electricity to be higher so the electrical production cost to be higher too. The purpose of this research is designing optimal configuration of microgrid PV-Wind turbine-Grid-Battery through optimization of load capacity to reduce excess electricity. Some parameters of optimal configuration are used to evaluate them, namely electrical production cost, reliability, CO2 coming from life cycle assessment, area of installation and unemployment reduction. Software HOMER version 2.68 Beta from NREL is used to simulate alternative configuration of microgrid. The results show that distribution total load into some sub-microgrids gives the positive impact, namely smaller electrical production cost, higher reliability, minimum CO2, relative smaller area of installation and unemployment reduction.

The purpose of this study is to find the level of trust of Indonesian consumers to C2C E-Commerce system in Indonesia. There are four antecedents of consumer trust will be measured and analysed to search the Indonesian C2C E-Commerce trust of Indonesian consumers. This study used the previous study that has been conducted about B2C E-Commerce system in Indonesia and also the similar study that has been conducted in United States of America. Gathering the data using online questionnaire and verify the data by interview some respondents, Structural Equation Modelling, Confirmatory Factor Analysis, and Squared Multiple Correlations were conducted in this study. Results from this study shows that the trust level of Indonesian consumers toward C2C E-Commerce system in Indonesia only 10.7%. Surprisingly, the users of C2C E-Commerce system are high, but the trust level is low, this is because of the third party recognition and some sellers do not provide a payment method that the buyers want and also there is no function that shows the reputation score of sellers.

Cochlear implant (CI) is a hearing aid for people with profound deafness, inability to respond to a sound stimulus above 90dB SPL. The main problem of CI user is the inability to discriminate simultaneous incoming sounds, focusing on the desired sound (target) whilst ignoring the rest (cocktail party problem). In this research, the release of masking strategy is introduced to give a glimpse of acoustical cues for CI user to make the discrimination easier in the presence of background noise (masker). We evaluated the performance release of masking with various combinations of target sound channel vocoder (the sound that want to hear) with respect to masker channel. For further enhancement, we also evaluated spectral subtraction (SS), Ephraim-Malah, and Frequency Amplitude Modulation Encoding (FAME) to improve intelligibility of channelized sounds. The results showed that the release of masking may have improve the intelligibility on CI users to access temporal structure of waveform of simultaneous stimuli. The best enhancement method is FAME with PESQ value 1.4 and % correct word increased to 72%.

The exponential growth of the data may lead us to the information explosion era, an era where most of the data cannot be managed easily. Text mining study is believed to prevent the world from entering that era. One of the text mining studies that may prevent the explosion era is text classification. It is a way to classify articles into several predefined categories. In this research, the classifier implements TF-IDF algorithm. TF-IDF is an algorithm that counts the word weight by considering frequency of the word (TF) and in how many files the word can be found (IDF). Since the IDF could see the in how many files a term can be found, it can control the weight of each word. When a word can be found in so many files, it will be considered as an unimportant word. TF-IDF has been proven to create a classifier that could classify news articles in Bahasa Indonesia in a high accuracy; 98.3%.

A maximum efficiency control for a dual-motor drive system is presented in this paper. The torque sharing between two motors is optimized by using the perturbation and observation method. A fuzzy-logic controller is implemented for the perturbation and observation method. As a result, the step of perturbation can be adaptively modified to improve the performance. In addition, a simple calculation is used to achieve real-time efficiency measurement. The proposed method is implemented on two identical 2 kW permanent magnet synchronous motors connected in parallel. Finally, experimental results validate the proposed control scheme performance.
