The driver behavior is the key to safe mobility. In general, vehicle maneuvers can be determined from acceleration of the vehicle. Physically, the acceleration and brake can be detected with longitudinal acceleration while turning and lane change can be detected with lateral acceleration. Normally, IMU (inertia measurement unit) has been designated to get those data. However, the I MU is not convenience to install in the vehicles especially as aftermarket additional parts. Nowadays, navigation system technologies have been much improved both on availability and accuracy with combination of multiple navigation satellite systems. Normally, it’s called Multi-GNSS (multiple global navigation satellite system). With decimeter precision and the update rate scale up to 10-Hz, the GNSS would be an alternative solution for driver behavior detection. This paper applied the behavior detection algorithm from previous study [3], and enhanced with advance Multi-GNSS;precise point position (PPP) technique. The advantage of PPP over conventional navigation is decimeter accuracy without direct connection to reference base station. The experimental Multi-GNSS receiver was JAVAD Delta G3T that installed on a utility vehicle. The navigation data was post-processed with the open source RTKLIB 2.4.2 software. On the other hand, the reference vehicle dynamic measurement system was VBOX 3LSi with integrated IMU. As results, the PPP improved the chance of detection of the algorithm from nothing in lane-changing to half of total incidents and significant improved on fault detected. Furthermore, the turning of vehicle which can be detected with conventional GPS was slightly improved with PPP by 15%. The limitations of current study are satellite availability that new block of navigation satellite still in commissioning phase and limited. Moreover, all experiments were carried out in Pathumthani, Thailand. Different city, location and satellite systems may obtain different results. In this pap

In this paper, a novel method is proposed for the Traffic Sign Recognition (TSR) using the Principle Component Analysis (PCA) and the Multi-Layer Perceptrons (MLPs) network. In particular, the candidate signs are individually detected from two chroma components in the YCbCr space and then classified into three shape classes: circle, square, and triangle based on computing the rotated version correlations. The PCA-based features of these objects will be used for the MLPs as the training system corresponding to previously determined class. This approach not only reduces the time but also increases the performance of the recognition process. In simulation, the proposed method is estimated with over 500 statistic images for the accuracy rate up to 96%. © 2014 IEEE.

In this paper we proposed an alternative approach to find the optimum solution of quadratic programming problems (QPP) in its original form without additional information such as slack variable, surplus variable or artificial variable as done in other favourite methods. This approached is based on the violated constraints by the unconstrained optimum. The optimal solution of QPP obtained by searching from initial point to another point alongside of feasible region.

Several neuroimaging studies have suggested that functional brain connectivity networks exhibit "small-world" characteristics, whereas recent studies based on structural data have proposed a "rich-club" organization of brain networks, whereby hubs of high connection density tend to connect among themselves compared to nodes of lower density. In this study, we adopted an "attack strategy" to compare the rich-club and small-world organizations and identify the model that describes best the topology of brain connectivity. We hypothesized that the highest reduction in global efficiency caused by a targeted attack on each model's hubs would reveal the organization that better describes the topology of the underlying brain networks. We applied this approach to magnetoencephalographic data obtained at rest from neurologically intact controls and mild traumatic brain injury patients. Functional connectivity networks were computed using phase-to-amplitude cross-frequency coupling between the δ and β frequency bands. Our results suggest that resting state MEG connectivity networks follow a rich-club organization.

A dual band monopole antenna for Wireless local area network (WLAN) communication system is presented. The antenna has been designed with two meander branch monopole elements and the rectangular ground structure with simple configuration. The first branch is optimized by using a quarter wavelength of desired resonance frequency at 2.45 GHz. Meanwhile, additional branch of second branch brings resonance frequency of 5.8 GHz. This can easily suited by using 50 ohm probe feed with SMA connector. The proposed antenna is simulated by using computer Simulation technology (CST) software in order to simulate the return loss, bandwidth, gain, directivity, surface current and radiation pattern. The impedance bandwidth for return loss less than - 10 dB is 284 MHz and 267 MHz for first and second resonance frequency. In fact, second resonance can be adjusted by modifying the second branch length, L B1 with little effect on the first resonance.

Previous studies mainly used radial basis, sigmoid, polynomial, linear, and hyperbolic functions as the kernel function for computation in the neurons of conventional support vector machine (CSVM) whereas orthogonal wavelet requires less number of iterations to converge than these listed kernel functions. We proposed an orthogonal wavelet support vector machine (OSVM) model for predicting the monthly prices of West Texas Intermediate crude oil prices. For evaluation purposes, we compared the performance of our results with that of the CSVM, and multilayer perceptron neural network (MLPNN). It was found to perform better than the CSVM, and the MLPNN. Moreover, the number of iterations, and time computational complexity of the OSVM model is less than that of CSVM, and MLPNN. Experimental results suggest that the OSVM is effective, robust, and can efficiently be used for crude oil price prediction. Our proposal has the potentials of advancing the prediction accuracy of crude oil prices, which makes it suitable for building intelligent decision support systems. © Springer Science+Business Media Singapore 2014.

In this paper, a vision-based target detection and tracking approach using improved multi-feature camshift is presented. Because the traditional camshift based on single feature is not robust when the background color, illuminate and target deformation change, it may lead to losing target or failure of tracking. In order to improve this problem, we presented target detection and tracking algorithm based on improved multi-feature camshift. The foreground image was obtained by Gaussian Mixture Model (GMM), which was used to modify the kernel function of target model. Due to the advantage of colour and texture feature in describing the target appearance, these features were used as recognition features. Additionally, EKF was integrated in tracking system to improve the accuracy of target tracking and predict the object position when the target was occluded. This paper details the architecture of the presented method and gives some experimental results to verify the effectiveness of the proposed method. © 2014. The authors - Published by Atlantis Press.

This study investigated the effect of continuous tones vibrant on focus ability among teenagers. Three vibrant levels as perceived as Medium, Loud but Comfortable and Very Loud were examined. In 6 subjects, the results showed that the amplitude of N1 waves have reduced significantly when stimulated by Medium sound as compared to Loud but Comfortable and Very Loud stimulation. Insignificant reduction of N1 amplitude was increased as the tones vibrant changed from Loud but Comfortable to Very Loud stimulation. In particular, the Very Loud stimulation evoked constant amplitude of N1 throughout stimulation in most of the subjects. This shows that a high vibrant of tones project high focus ability. The finding could be used for a basis of developing an awareness system or a diagnostic for mental disorder such as schizophrenia.
