In this paper, we determined the appropriate number of clusters and the proper amount of entries for applying K-means clustering to TCPdump data set using Apache Mahout/Hadoop framework. We aim at finding suitable configuration for efficiently analyzing large data set in limited amount of time. Our implementation applied Hadoop for large-scale log analysis with data set from KDD'99 competition as test data. With the distributed system framework, we can analyze a whole data set of KDD'99 by first applying our preprocessing. In addition, we use an anomaly detection model for log analysis. A key challenge is to make anomaly detection work more accurately. For the Kmeans algorithm, a key challenge is to set the appropriate number of the initial cluster (K). Moreover, we discuss whether the number of entries in log files affects the accuracy and detection rate of the system or not. Therefore, our implementation and experimental results describe the appropriate number of cluster and the proper amount of entries in log files. Finally, we show the result of our experiments with accuracy rate and number of initial cluster (K) graph, ROC curve and detection rate and false alarm rate table.

This paper aims to establish an innovative scheme for compensating the dynamics of the benchmark plant by employing especially two parallel PID controllers and their output-weighting method. These PID controllers are fitted by different tuning-rules and the multipliers for their output-weighting are on-line adapted so that the error of the closed-loop response disappears more rapidly than the cases of using each single PID controller alone. Simulation results confirm feasibility and effectiveness of the proposed methodology.

In recent years, improving of power factor and reducing harmonic distortion in electrical instruments are needed. In general, a current conduction mode boost converter is used for active PFC (Power Factor Correction). In a PFC boost converter, if a duty ratio, a load resistance and an input voltage are changed, the dynamic characteristics are varied greatly. This is the prime reason of difficulty of controlling the interleaved PFC boost converter. In this paper, a robust digital controller for suppressing the change of step response characteristics and variation of output voltage at a DC-DC buck converter load sudden change with high power factor and low harmonic is proposed. Experimental studies using a micro-processor for controller demonstrate that this type of digital controller is effective to improve power factor and to suppress output voltage variation.

Nowadays, fiber to the home (FTTH) is considered to be the access network technology that can offer the highest speed compared to others. Certainly, the FTTH service providers aim to create the largest profit but the problem is the negligence of development strategies that will achieve the optimum objective values. To obtain the best strategies, the optimization model is proposed. This paper performed techno-economic analysis by using our proposed model in order to optimizes the tactics. Results from simulations show that operator k could make more profits than rivals when the strategies obtained from our modeling are used.

This paper presents a new approach to include fading effects due to human in a wireless link and exploit it for activity recognition. It is proposed as a low-cost, low complexity solution for detecting human activity by considering fading characteristics of received signal strength (RSS) at 2.4 GHz frequency on commercial IEEE 802.11 devices. The RSS mean and the fluctuation analysis (FA) are two features extracted and used for developing a recognition procedure. To evaluate accuracy performance, RSS measurements from four human activity scenarios are performed at three different environments. Collected RSS data are used for the supervise-based activity recognition scheme proposed in this paper. From the experiment, this approach can achieve on average of 90% accuracy or higher in classifying four selected human activities at separation distance of 5 m between a transmitter and a receiver. Recognition accuracy values at other environments/settings are slightly dropped due to the growth of possible unblocked multipaths, but the accuracy performance is still attained within acceptable level. The histograms or RSS distribution obtained from different human activity scenarios are also considered and analysed. Finally, the proposed approach provides decent accuracy outcomes and it demonstrates pertinence to be adopted in the future intelligent pervasive system.

In this study, a technique designed to enhance virtual reality (VR) effects by stimulating multiple sensations simultaneously is investigated and significant interactions among such perceptions are evoked under various multiple-simultaneous stimulation conditions. To accomplish this, we developed a handheld multimodal display device capable of presenting visual, weight, and vibrotactile information simultaneously. The device incorporates a liquid crystal display (LCD) panel, a back-mounted moveable weight, and vibration motors in the handgrips. The weight movements are produced by a linear motor controlled by a personal computer (PC). Using this handheld device, it was determined that VR perceptions could be enhanced by the interactions taking place among multimodal perceptions. In this paper, experiments on weight perception along with the affects of vibrotactile stimulation are described. Using our developed handheld vision-tactile-force display device, we investigated the interactions between force and vibrotactile perceptions that were stimulated simultaneously. This indicates that when strong vibration stimulations were given in the direction of weight movement, the weight seemed heavier. The experimental results and conclusions show that weight perception and vibrotactile stimulation could be enhanced using our handheld multimodal display device.

A prototype of smart sniffing shoes with wireless data communication has been developed as a wearable medical instrument. This intelligent system can be divided into two major parts: (i) chemical gas sensor array installed inside the shoes for foot health monitoring and (ii) wireless data communication using ZigBee technology. The gas sensors for odor sensing were created by embroidering the sensing materials onto a fabric substrate then installed inside the tongue of shoes. Moreover, it was designed as a removable system, convenient for maintenance and cleansing. The embroidered sensor array has been tested with various single chemical components of volatile organic compounds (VOCs) with low concentration in a static system. It was found that these sensors could provide a good sensitivity and fast recovery even operated at the room temperature. For preliminary testing on an actual application, this wearable e-nose system was applied to monitor the foot odors, of which results have demonstrated that this system could distinguish foot odors in each duration time. Principal component analysis (PCA) was used to confirm the classification of individual foot health.

This paper presents a linear chrominance gain slope equalizer for correcting the linear chrominance gain distortion in the color TV transmission system. The proposed gain slope equalizer was based on Bernstein polynomials. As it is known that the Bernstein filter is best for linear phase characteristic. In addition, the modulated 20T sine-squared pulse test signal is utilized for testing the performance of the proposed gain slope equalizer, which can be corrected the linear chrominance gain distortion. As the results, the proposed gain equalizer is also proved to be efficient in equalizing both the low gain and the high gain chrominance distortions without degrading its phase characteristics.
