A Study on the Use of Multicast Protocol Traffic Overload for Active Network
Authors: Choi Won Hyuck , Jie Min Seok
Published: July 2013

Multicast requires reliability in one-to-one or multi-counterpart communication services and such demand for reliability becomes more and more an important factor to manage the whole network. In addition, it requires link of broadband network, real-time transmission, and much effective multicast protocol in order to support application of multimedia that has become a dominant figure recently. Communication method for multicast is a way of communication for a transmitter that provides multicast data to every registered member in the transmitters group, and it can be classified into the traditional and the reliable communication methods in general. The traditional communication method is very fast in connection but quality of service is poor. In contrast, the reliable communication method provides good quality in service but its speed is somewhat poor. Thus to enhance such demerits, this thesis proposes communication method of multicast by using active network method. In this thesis, a fair and practical bandwidth is used for data packet transmission along with the use of active network. The bandwidth and data processing capability filters out the transmitted data from an active router through transmission packet and upgrades multimedia data packet more effectively. Therefore, recipients in various levels receive the effective data packet and based on these facts, the study actualizes and evaluates efficiency of a router, which is able to transmit the fair bandwidth from active router in a simulation.

Published: July 2013

An experiment was conducted on densification processing of sorghum straw stalks with self-made steel molds on a hydraulic universal test platform. The influences of different densification conditions on physical quality of briquette fuel are investigated, including pressures, temperatures, moisture contents and straw preheating method. Moreover, the relationship between molding temperature and inner stress decreasing rate of straw briquette at holding pressure stage is also analyzed. The result shows that the suitable value of moisture content, temperature and molding pressure for straw compression process is 20%, 90°C and at least 50MPa, respectively. The phenomenon of uneven temperature distribution in straw briquette keeps in existence even in the case of microwave preheating. However, in contrast with the very low central temperature in straw briquette when preheating by electric heater wire, the phenomenon of local overheating caused by microwave preheating may be helpful to straw molding process.

Authors: Chen Chao , Zhou Shi Jie , Luo Jia Qing , Chen Yan Pan
Published: July 2013

In an intensive RFID reader environment, multiple RFID reader are deployed together to cover a pointed area. In such intensive RFID reader application, it needs to determine how many readers are enough to cover the expect area and calculate the position of readers. However, the coverage of multiple readers is a NP problem. Therefore, it needs an approximate approach to optimize the coverage. In this paper, we proposed a lattice decentralized approach to model the coverage problem of intensive RFID reader deployment. In our novel model, both the deployment area and the reader reading region are discretized to a lattice and described by a matrix. Then, the coverage is easily calculated by matrix operation. In order to test our discrete method, we propose a heuristic algorithm to deploy readers based on the PSO (particle swarm optimization) algorithm. The simulations show that the proposed algorithm can cover an irregular or regular area with a high coverage rate and a low overlapping rate.

A Wavelet Spatial Correlation Algorithm to Partial Discharge Denoising Based on MDL Criterion
Authors: Tian Li Song , Chen Wei Xuan
Published: July 2013

The partial discharge (PD) detection systems are often vulnerable to strong external interferences, and sometimes the PD signals are submerged in noises (white noise for example) completely. So the signals acquired must be preprocessed to obtain the reliable PD information. While there are many methods for white noise denoising, mostly are not very suitable for partial discharge. The wavelet transform (WT) coefficient of PD and white noises have different spread characteristics in different WT scales. Based on the Information Theory, The Minimum Information Description Length (MDL) criterion is a optimization strategy, a small amount of signal parameter is requried to the PD signals representation, the paper proposes a wavelet spatial correlation algorithm to partial discharge denoising based on MDL criterion: optimal wavelet function is selected based on MDL, then have the white noise reduced in WT, the algorithm has wonderful virtues such as free from any parameters estimation about noise, free from presetting threshhold and threshold chooseing behavior, so the algorithm is highly adaptive. Large amount of experimental results illustrate that the method presented in this paper are efficient and feasible and outperforms other general method of PD noise reduction.
