This paper proposed a method to calculate the operating point of photovoltaic (PV) generation system under shading effect. To simplify the algorithm, the graphical method is used in this research. The PV modules in each string are divided in to two group, i.e. shaded and unshaded groups. In addition, the double diode model with Bypass diode is proposed in this paper. This model is used to investigate the output characteristic, i.e. current, voltage, and power. The characteristic given from the PV model is used to plot the I-V and P-V graph for each PV group. The characteristic of each group is combined together to obtain the characteristic of the whole string. The graphical method is used to specify any peak power that occurs under shading effect. The result shows that the proposed method can determine the operating point of PV system when shading effect occurs without optimization.

This paper presents a simple temperature control for high efficiency induction cooker based on class-E DC-AC resonant inverter. The active switch can be operated under the zero-voltage switching conditions. The conduction loss of the anti-parallel diode of the active switch and the harmonic currents injected into the public supply system can be reduced. The high power-factor and low line current harmonic distortion can be obtained, which are very attractive in term of commercial production. In order to achieve upon this objective, the induction cooker's parameters need to be designed properly and details of analysis and design of this induction cooker's components are described. A proposed high efficiency induction cooker is designed for an operating at a 32-kHz frequency, a 220-V line rms voltage, a 50-Hz line frequency and a 1.2-kW output power.

Normally power supplies provide a constant output voltage. A DC-DC converter in most of the applications is controlled by a voltage mode or a current mode controller. The DC converters are employed to feed electric vehicles, telephone sets and civil invertors, or for induction motors and frequency control. In this regard, optimal exploitation of DC transformed by classical controllers has been a controversial issue in reputable journal publications. Due to their switching property included in their structure, DC-DC converters have a non-linear behavior and their controlling design is accompanied with complexities. However, by employing the average method, it is possible to simplify the system as a linear system and exploiting linear control methods. In this article, an attempt is made to control the buck converter by PI and PID controllers. By using PID controller and genetic algorithm, a new adaptive control method model is introduced. A Genetic algorithm is applied to discover the supreme values for PID controller's parameters within a short time period. The improvement of the current control response is the result of the simulation.

Corrosion defect is one of the important defects found in hard disk drive manufacturing. Fail to detect this defect might lead to fatal hard disk drive failure. In general, corrosion defect was found after the end of process. The fundamental methodology used to measure corrosion defect in head magnetic process of hard disk drive manufacturing is Electrochemical impedance spectroscopy (EIS). This method applies a low frequency voltage to a chemical cell in order to measure corrosion rate which is defined as a reaction of material in aqueous solution. The data obtained from EIS measurement method are complex and thus hard to analyze. Furthermore, EIS method is destructive materials measurement and the obtained results cannot well predict corrosion behavior of the system. However, head magnetic materials/slider is a stack of three materials in layers i.e. soft magnetic layer, diamond like carbon (DLC) layer, and photoresist layer respectively. These three stack layer of slider can be replaced by R-C equivalent circuit. Nyquist plot and Bode plot are used to observe the frequency response of the equivalent circuit. This observation can help in prediction of corrosion behavior before starting of mass fabrication or transferring to new materials. This work shows that the results obtained from an equivalent R-C circuit model of copper substrate coated with photoresist and the one obtained from EIS method are comparable. It should be noted that the parameters of R-C equivalent circuits are modified for corrosion behavior studying according to two different types of photoresists.

The heat cycles test set is designed and built in accordance with what is discussed in the article for high voltage cables testing [1, 2]. The test set feeds current periodically into the cable under testing. In on-cycle, the test set heats up the cable for at least 8 hours while in the off-cycle, it allows the cable to cool down for at least 16 hours until its conductor temperature is within 10 °C above the ambient temperature. The current that is fed into the cable during the on-cycle is to be recorded for 2 consecutive hours when the conductor temperature remains constant as per the insulation standard (IEC 60840-2004). The heat cycles test set has two separate current sources, which can be used independently. Programmable Logic Control (PLC) is used in controlling the operations of the test set, e.g. the two current sources can be programmed to work together, moreover, the number of testing cycles, feeding current, and also the resulted temperature of any on-cycle can be selected. In conclusion, the test set built as described, can perform its functions satisfyingly while accomplishing cost reduction. This is because an imported test set of the same kind is more expensive. Besides, a digital recorder is installed for recording temperature and current during testing. An acceptable error of 1.45% to -1.62% of the test set is obtained when undergone the calibration.

Our developed protocol Energy Aware Mesh Routing EMRP is a robust, cluster-based routing technique used in Wireless Sensor Network (WSN). It can provide a reliable, scalable, energy efficient multipath routing mechanism for data transmission to Base Station (BS). This scheme is also classified as a routing technique supporting virtualization WSN (VSN) as it can share network resources between different VSNs for achieving resource efficiency. In this paper, we propose a new dynamic switch process for EMRP that use the current energy value of relay and backup node and evaluate the performance of new switch strategy in terms of total residual energy, load balance, network lifetime and rate delivery compared with the old scheme. Via simulation, we realize that the newEMRP protocol can achieve better rate delivery and load balance than EMRP. Furthermore, we analyze and evaluate an application case of virtualization in OMNET++ that utilizes our two routing algorithms in order to investigate the capability of collaboration and network resource sharing between different VSNs. Our simulation result shows that both schemes can achieve collaboration and efficient network resource sharing for the purpose of virtualization. More concretely, the newEMRP protocol can achieve better capability of network resource sharing than the old protocol.

This paper proposes the application of the battery energy storage system (BESS) to be installed in the distribution system for the purpose of postponing the investment of the distribution reinforcement in the short term power distribution planning. A study case of the distribution system including the photovoltaic system and the BESS obtained from the Provincial Electricity Authority (PEA) is used to evaluate the requirements of the BESS to be installed in the distribution system by considering four types of loads which are household, small enterprise, industry and other types. It reveals from the study that the installation of the BESS can effectively extend the time of the new distribution line construction.

Abnormal respiratory rates have been shown to be an important predictor of serious clinical illness, but respiratory rate is a vital sign that is often not recorded because methods for measuring respiratory rates are cumbersome. We propose an approach to record and monitor respiratory rate of a patient that is lying down by placing an accelerometer-equipped smartphone on the patient's chest. We develop an algorithm based on fast Fourier transform (FFT) to estimate the respiratory rate from the noisy acceleration data. The main contribution of this paper is that our proposed algorithm can estimate respiratory rates using only tri-axial acceleration data from sensor in commodity smartphones without any other special equipment. Preliminary results show that our method can reasonably estimate the respiratory rate.

This paper presents development of a long duration impulse current generator for testing surge arresters in distribution systems. The developed generator was designed by hand calculation at the beginning stage, then with the help of EMTP/ATP simulation. The design of the generator circuit parameters (resistors, inductor, and capacitors) is provided in this paper. The effect of internal resistance of an inductor to the current waveform is presented. An approach for adjusting the circuit parameters of the generator to obtain the current waveform accordance with the standard is also proposed. The generated current waveform has met the requirements of IEC standard. The developed long duration current generator was employed to generate current for testing a surge arrester in an HV laboratory.
