Detection of partial discharge (PD) in the frequency range ultrawide band (UWB) provides some benefits such as in a more accurate observation of the PD pulse shape and the PD frequency spectrum. One method to measure the PD signals in the UWB frequency range is by using the PD detecting impedance circuit. The 50 ohm detecting impedance is used as a coupling device to maximize power transfer of PD current. This paper design the matching impedance circuit comprising an impedance detector as attenuator and UWB amplifier as a signal amplifier. S-parameter characteristics of the circuit is simulated in software Advanced Design System (ADS) software. The PD detecting circuit is made and it is tested using Vector Network Analyzer (VNA) instruments. Then, the circuit is used to measure PD on the needle — plates electrode in the air.

This paper proposes new step-up DC-DC converters with high ratio capability. The proposed DC-DC converters are derived using combination of boost converters and buck-boost converters. A high ratio capability is achieved by parallel input and series output combination so that the efficiency is better than the one that is achieved by using a conventional boost converter. A method to reduce the input and output ripples are also proposed in this paper. Simulated and experimental results are included to show the validity of the proposed converters.

Hybrid Electric Vehicle (HEV) is vehicle with least two energy sources. Internal combustion engine (ICE) and BLDCM are combination of commonly used energy sources. BLDCM serves to provide additional torque, with the purpose of HEV can reach set point speed according to the reference model. Commutation of BLDCM is still quite complicated because between the rotational speed of the motor and the speed of the rotary field on the stator shall be kept synchronized. Self Commutation is used to maintain synchronization between the rotation of the rotor to rotary field velocity on BLDCM stator. In addition, this research also applies torque control strategy using fuzzy-PI controller. The BLDCM Self commutation scheme can be applied to the HEV plant. The applied strategy can reduce undershot at HEV speed by represents steady state error value of 0.0049 rpm.

Brushless DC (BLDC) motors have been applied extensively in household and industrial scale because of the advantages such as high efficiency and low mechanical losses because it does not use a brush such as DC motors. Application of the BLDC motors use rectified AC source to minimize battery usage. However, the use of BLDC motors and rectifying circuit causing poor power factor and facing harmonic problems. At rated power, BLDC motors have power factor about 0.58 while the current THD at 73%. These values are outside the permitted tolerance limits. This study aims to improve power factor and THD value of current caused by the operation of brushless DC motors using a SEPIC converter. Moreover, the purpose of this study is that the motor is able to operate at different levels of speed and various loads. The results of the simulation of the design have been made, the motors can respond to variations in the speed reference given to the good. The control circuit is also able to make the motor maintain pace with changes in the load every time. Power factor observed at source will rise until 0.99 at various speeds. In addition, the current THD has an average value of 2% at various speeds. Both of these parameters are within the tolerances allowed by the standard.

This paper presents a new implementation of flyback-type inverter to optimize power flow from solar PV (photovoltaic) system. The flyback-type inverter used is Shimizu topology. The main features of this inverter type include: extended lifetime of the inverter, provide small volume, lightweight, lower harmonic content and stable AC current injection into the load or utility line. Three controllers used comprise non-MPPT, conventional Incremental Conductance (IC) and IC+PID method. To verify the effectiveness of the inverter design, such methods are examined with different irradiance conditions. The results show that the Shimizu flyback-type inverter exhibits considerable optimum performance and can harvest a good maximum power under different irradiance conditions. The results also indicate that the IC+PID method gives less harmonic distortion.

In this paper, we focus on the problem of collision in tags identification in RFID systems. We propose tree algorithm with single error bit tracking that utilizes Manchester coding to know the position of collision bit among the ID of the tags. The reader broadcasts the Query bit that is updated in every collision. The update is done according to the position of the collision bit that allows to reduce the idle slots. Based on the comparison results, the proposed algorithm provides improvements to the existing tree algorithms.

The region of interest (RoI) has the most useful information in image processing since the targeted objects are covered in this area. By determining the precise position of RoI, a computer-based identification will be able to work more efficiently, to give a better contribution in system and to eliminate objects that may intrude overall process. In malaria disease, the existence of Plasmodium can be observed from patient's microscopic thin blood smear images. Having utilised the computer aided detection based on image processing, malaria disease can be detected earlier and more objective in order to support the final decision of paramedics. This study proposes a novel method to automatically determine the region of interest (RoI) on thin blood smear images for facilitating the process of Plasmodium parasite detection. The approach includes Otsu thresholding method, morphological operation and binary large object (BLOB) analysis. Evaluation results on 24 thin blood smear images show that the proposed method achieves the sensitivity and PPV rates of 87.5% and 75.7%, respectively. These successful results in automatically determine the RoI which contains the Plasmodium parasite indicate that the proposed method has a potential to be implemented in the development of a computer aided malaria detection system.

All mechanical and electronic systems can run into performance degradation including robot Manipulators. One cause of such performance degradation is due to the occurrence of fault on the actuator. The occurrence of actuator fault on Robot Manipulator 2 DOF (Degree of Freedom) will make tracking of the robot shifted from its reference, cause signal deviation and enlarge overshoot. Estimation and compensation techniques can be a solution to this problem, but these techniques can only be done if the designed system is capable of generating residual signals. This signal is a comparison of the response signal between the actual system and the MRC response signal. This paper explains the design of an AFTC (Active Fault Tolerant Control) algorithm based MRC. When an actuator fault happened, it was estimated and compensated with Model Reference Control (MRC) using Proportional Integral Derivative (PID) based on Computed Torque Control (CTC) law. Simulation result shows that the designed system can compensate actuator fault with small error tracking error about 0.0068 rad and has time response less than 1s. It also reach minimum overshoot through 0.041 rad.

Energy Harvesting (EH) is now becoming popular due to promising long lasting life time of communication system. Some of the communication systems use EH device as their energy source. However, EH also has a limitation that is shown in its characteristics as random arrival and scarce of energy. Both of limitation is very influencing the system performance and the number of transmitted data. As we know the more energy is harvested, the longer system can operate. Because of EH limitation, the system with EH device needs to adjust to get the maximal channel capacity. This paper proposes the cooperative communication system with modified decode and forward (DF) method and EH device as a source energy. The modified DF method incorporate adaptive modulation at relay node to transmit data to the destination node. To test the proposed system, in this paper, three different scenarios are simulated, i.e. the non cooperative communication system with EH device as source energy, the cooperative communication system with DF method but fixed modulation level and EH device as a source energy and the proposed system. The simulation result shows the channel capacity of the proposed system is better than two other scenarios.
