To improve the accuracy and efficiency of coal and gas outburst prediction, the principal component analysis was combined with radial basis function neural network for the prediction of the situation of coal and gas outburst in this paper. The impact factors of coal and gas outburst in a coal mine are the object of the study. Principal component analysis method was used to extract the principal component factors, and then the large contribution of three principal components was selected to replace the original nine factors, with the main ingredient as an input parameter radial basis function neural network. Coal and gas outburst is divided into four levels to build predictive models of coal and gas outburst. 16 outstanding groups of typical samples of the neural network prediction model were selected for training, and three groups of testing samples were tested with trained neural network prediction model, with results showing that projections are consistent with the actual situation.

A dual-band low noise amplifier (DBLNA), which can operate at 2.4 GHz and 5.8 GHz, is designed and realized. Infineon BFP740 SiGe HBTs are chose as active device, the cascode structure with high isolation and wider bandwidth is selected as gain circuit stage, whose bias current is selected to obtain minimum noise figure. In order to cope with the error of board technology and the PCB transmission loss, an additional stage is added into the cascode amplifier stage, both the peaking inductor and the RC circuit are utilized to compensate the decrease of high-frequency gain. A voltage divider circuit by resistor is employed to provide bias current, and the bias point is determined by scanning IB-NF. For the sake of miniaturization and adjustability, the π-type micro-strip line is used to achieve input/output matching. The combination of the electromagnetic simulation and the schematic diagram simulation, so-called co-simulation, is used to guarantee the simulation results are close to actual case. Finally the board-level layout is designed and the DBLNA PCB is fabricated and measured. © 2014 WIT Press.

Recommendation systems have been widely used in social media. One of recommendation tasks in social media is to provide relevant messages for users. Although many models have been proposed, how to make accurate recommendation for new users with little historical information still remains a big challenge, which is called the cold start problem. In order to address this problem, many models have been proposed, which use information of social media to improve the recommendation performance. However, lack of such versatility limits the successful application of these models. In this study, we propose an effective facet-based trend model to describe the trend interests of the entire user community in social media. Trend facet is the probability distribution of all users' preference to an attribute. In contrast to the general feature, the facet stems from the users' history and captures the interests to the attribute in social media. We evaluate our models in the context of personalized ranking of microblogs. Experiments on real-world data show that trend modeling can alleviate the cold start problem significantly. In addition, we compare the performance of user modeling and trend modeling, and find that user modeling outperforms trending model and the impact is slightly negative when combining trend modeling with user modeling. © 2014 IEEE.

International Journal of u- and e- Service, Science and technology 2014年第2期7卷 77-82页

The granary monitoring systems in used in China are mostly based on wired networks such as RS-485 serial bus, CAN fieldbus, etc. Inevitably these monitoring systems have drawbacks of high installation cost, high failure rate and high maintenance cost. Aiming at these problems, this paper designed a granary temperature and humidity monitoring system based on Zigbee wireless network. The monitoring system consists of sensor modules as Zigbee end devices, a host PC connected to a Zigbee coordinator and some Zigbee routers if necessary. The sensor module is a temperature and humidity testing device using a CC2430 as the controller and a SHT11 as the sensor. All testing results are displayed as figures and curves in real-time on the host PC, and history data are saved in a database file for further analysis. © 2014 SERSC.

The conventional Mie-scattering calculation has been widely used for spherical particles existed in a vacuum and homogeneous nonabsorbing medium. The paper investigates the radiative properties of particles existed in absorbing medium, including light absorption, extinction efficiencies, scattering efficiencies and so on. This study presents milk fat globule in ethyl acetate solution (EAS) and monoethanolamine (MEA) solution including their complex refractive index. The complex refractive index of milk fat globules at 20 °C was measured at 633 nm and was calculated to be 1.46+0.000005i, the complex refractive of EAS was measured at 633nm and was separately calculated to be 1.476 + 0.0005583169i. We considered the calculation difference of the efficiency factors by comparing results from inherent efficiencies and apparent efficiencies of milk fat globule in absorbing medium by simulation in MATALAB. By simulation it is proved that the light scattering by globules is affected by absorbing medium, so modifying Mie scattering calculation is necessary.

The rank one NMF blind source separation algorithm (NMF-R1) was obtained by imposing the sparsity constraint on the fast NMF algorithm based rank one. NMF blind source separation algorithm based on least squares (NMF-LS) was obtained by using pseudo-inverse matrix. NMF-R1 algorithm was superior to the existing blind source separation algorithms based on NMF. NMF-LS algorithm had faster computation speed, but the result of decomposition was not unique. In order to further enhance the signals separated performance, crossover iteration between NMF-R1 and NMF-LS was used to getting the mixing matrix and the signal matrix, and the mixed NMF blind source separation algorithm (NMF-LR) was obtained. Simulation results show that the separation performance of NMF-LR algorithm is better than that of NMF-R1 and NMF-LS, and the computation complexity of NMF-LR algorithm is nearly the same as NMF-R1 algorithm. © (2014) Trans Tech Publications, Switzerland.

Markov fuzzy based mac protocol for life time maximization of wireless sensor network

引用

International Journal of Computers and Applications 2014年第4期36卷 133-139页

作者： Venkataramanan, Chakrapani Girirajkumar, Selvaraj M. Department of Electronics and Communication Engineering Kurinji College Engineering and Technology India Department of Instrumentation and Control Engineering Saranathan College of Engineering India

This paper jointly investigates the problem of duty cycle adjustment and the slot allocation in the time division multiple access (TDMA)- based wireless sensor network systems. In this proposed Markov Fuzzy Medium Access control (MaFuMAC) protocol, the duty cycles of the nodes are adjusted by the hidden Markov model, and the slots in the TDMA channel are assigned to the nodes in the cluster, based on the fuzzy slot priority (FSP) function. The FSP function is computed by using the parameters such as weighting function, queue length and delay factor of the individual nodes for achieving the conflict-free scheduling. The simulation results of the proposed approach significantly improve the life time of the nodes in the network with less energy utilization and delay.
