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.

This paper proposes a real-time algorithm of Premature Ventricular Contraction (PVC) detection based on a low computational method. This algorithm considers three time-domain features which are RR-interval, QRS-width and QRS-pattern. Simple decision rules are used in the classifier process which is suitable for embedded applications. The algorithm was tested with 26 ECG records from MIT-BIH Arrhythmia Database (MIT-DB). After evaluation, the performance of the proposed method has 91.05% of sensitivity and 99.55% of specificity.

This paper presents a preliminary study of a novel approximate UTD ray solution of an oblique electromagnetic (EM) diffraction by an impedance discontinuity in a planar surface. The proposed solution is heuristically obtained from the Weiner-Hopf (W-H) solution. This leads the proposed solution relatively simple and closed form expression which is suitable for engineering applications. The comparison between the proposed solution and the W-H solution also preformed and shows good agreement for all the co and cross-polarizations.

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.

To travel within the real world safely, an autonomous mobile robot has to perform obstacle avoidance. One of the most popular approaches to solve local obstacle avoidance is Dynamic Window approach. This approach is to search optimal control command of the robot in velocity space directly. The command which maximizes objective function is then selected as output command. In the original Dynamic Window approach, in order to avoid obstacles, it concerns only obstacles on robot's trajectory. Therefore, the robot might crash with some obstacles which are near the trajectory but not on the trajectory. Therefore, in this work, we propose field Dynamic Window approach (F-DWA) which objective function is modified to consider the obstacles near the trajectory as well. This can be done by the use of histogram grid representation of obstacles to estimate the crashing probability of the trajectory. The objective function of Dynamic Window approach also depends on the crashing probability as well as other traditional factors. To test the robustness of proposed algorithm, experiment in real world is conducted. The result is the robot can travel safer when it concerns near-trajectory obstacles.

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 present investigation on plasma monopole antenna using a single fluorescent tube and reviews the antenna performance as a transmitter and receiver. From the measurement it is shown that plasma antenna is just effective as metal antennas and it can work as a transmitter and receiver signals. Plasma antenna consists of glass tube filled with some neutral gases such as Argon. In the experiment a commercially available fluorescent tube function as a plasma antenna, with length 0.31m (l) and diameter 0.031m (r) is used as the plasma antenna. The tube was energized by 12 V DC, and 0.8 A current, which is provided by a standard DC power supply. The DC power supply was connected to DC ballast before directed to both electrodes of the fluorescent tube. A Vector Network Analyzer (VNA) is connected to coupling sleeve. This simulation is performed by using the simulation software Computer Simulation Technology (CST) Microwave Studio. The frequency target range 700MHz until 900MHz which is this frequency can apply in ultra high frequency (UHF).

We use energetic arguments to describe a scenario of self-assembled InP quantum dot (QD) formation during crystallization of indium nanodroplet. Competition between strain energy and surface energy of a homogeneous circular ring and a ring-shaped QD molecule results in QD formation at critical ring size. From the described process, we expect to extend our ability to realize complex nanostructures, which might be promising for future electronic and photonic applications.

In this work, we consider network intrusion detection using fuzzy genetic algorithm to classify network attack data. Fuzzy rule is a machine learning algorithm that can classify network attack data, while a genetic algorithm is an optimization algorithm that can help finding appropriate fuzzy rule and give the best/optimal solution. In this paper, we consider both wellknown KDD99 dataset and our own network dataset. The KDD99 dataset is a benchmark dataset that is used in various researches while our network dataset is an online network data captured in actual network environment. We evaluate our IDS in terms of detection speed, detection rate and false alarm rate. From the experiment, we can detect network attack in real-time (or within 2-3 seconds) after the data arrives at the detection system. The detection rate of our algorithm is approximately over 97.5%.

Linear-phase FIR filters that was successfully designed by PSO method has good frequency-response shape (low output ripple). However, Linear-phase FIR has so many trigonometric terms and requires complex-number calculation. This leads to two major problems for PSO (and similar algorithms), slow and faulty convergence (especially at high filter's order). This paper proposes `Zero-phase Pre-design' technique. The technique firstly designs zero-phase FIR filter (using PSO) and then converts it to linear-phase FIR (the conversion is easy). For zero-phase FIR, we can mathematically reduce trigonometry terms and discard imaginary terms in design calculation, result in computation saving and less difficulty. Experimental results show that our technique prevents design failure and need less computation time.
