This paper discusses the enhancement using blob analysis applied to automatic segmentation of “GrabCut” tool [1] for segmenting blooming flowers in color images. The automatic segmentation of “GrabCut” is used to initialize the segmentation, but the results are not effective and there is insufficient separation of foreground and background color distributions. In our proposed work, the segmented “GrabCut” image in RGB format is first converted to a binary image based on the V plane of the HSV color space. The morphology operators combining with set operations are then applied to fill up the holes of blob. This is then followed by blob filtering to eliminate the unwanted connected region. Finally, the segmented binary image is converted back to its RGB form. The proposed enhanced method achieves a more efficient extraction of blooming flower in a complex environment which cannot be trivially eliminated by the automatic segmentation of “GrabCut”.

Indoor WIFI localization is challenging especially when deployed over wireless device with limited system resource. Although GPS can give approximate position of the mobile users, it is usually limited indoor due to the degradation of signals by the building structures. While various alternative WIFI localization techniques have been proposed for indoor uses, accurate results are hard to achieve due to the instability nature of wireless signal. In this paper, we discuss the performance of multi-trilateration and fingerprinting localization techniques in the context of mobile applications. The implementation of WIFI localization on mobile allows the users with WIFI-enable devices such as smartphone to locate their position and/or navigate themselves within the building. During our experiments, we noted that the selection criteria that involves selecting available access points to be used as a reference position considerably affect the accuracy of the positioning calculation. The tradeoff between multi-trilateration and fingerprinting in terms of correctness, computational complexity and system resource consumption have been discussed. Additionally, we proposed the suitable configuration for these localization algorithms as a means to achieve more accurate positioning results.

This paper presents a risk assessment tool for power transformers in central region substations of Provincial Electricity Authority (PEA) by using health index, which is computing from history and condition weighted scores. The maintenance data from 237 power transformers in central region are used to analyze the risk factors' ranking and scores. The weights of the risk factors are assigned by experienced maintenance crews. The risk assessment factors and scores are categorized with equal weight into two parts: the history of the transformer; and the current condition of the transformer. The weighted scores from both parts are calculated to obtain the health index (HI) for the power transformer. The HI is then plotted on a square matrix called the “health-index matrix”, which interprets the risk condition for that transformer. The risk assessment method proposed in this paper is applied to three power transformers in different load areas in central region of PEA. The results show that the method successfully detects the risk condition of those transformers. Therefore the proposed method can create an efficient preventive maintenance plans for power transformers in central region of Provincial Electricity Authority.

This paper presents a three-phase constant output power control scheme of an induction heating system using an automatic variable-frequency symmetrical voltage-cancellation (AVFSVC) control technique. The control scheme is based on a product of current and voltage in the induction coil. The resulting instantaneous output power is filtered and compared with a reference value. The output power can be automatically adjusted according to the power requirements by varying the duty cycle of switches where the power control range is expanded. The operating frequency-tracking is controlled by a phase locked loop (PLL) control for maximum overall system efficiency. The switches operate under zero voltage switching (ZVS). The validity is verified through the simulated results on the output power ranging from 0.03 to 16.5 kW under 15.12 to 16 kHz operation frequency.

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%.

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.

Orthogonal Frequency Division Multiplexing (OFDM) is a popular technique in the wireless communication systems which can achieve high transmission data rate with high signal quality even in the multipath fading channel which is a typical operation condition under wireless communication systems. MIMO (Multi Input-Multi Output)-OFDM is also considered as a promising technique for realizing the future ITS services. In this paper, we propose a new road to vehicle communication system (RVC) for the ITS by using the STBC MIMO-OFDM technique which can achieve a high transmission data rate with high signal quality even under the high mobile ITS environments.

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.

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).

In this paper, the far-field radiation of an electric Hertzian dipole embedded in electromagnetic bandgap (EBG) structures of periodic lossless multilayers is studied analytically and numerically. To simplify the analysis of this radiation problem, the equivalent transmission line (TL) model based on conjugately characteristic-impedance TLs (CCITLs) is employed to efficiently compute the far-field radiation of the Hertzian dipole, where associated reflection coefficients, which are useful in computing far fields, can be determined effectively. Numerical results based on equivalent CCITL models are in good agreement with results obtained from a commercial electromagnetic software.
