Study on Thermal Degradation of Phenolic Resin
Authors: Chen Zhi Qin , Chen Yang Fei , Liu Hong Bo
Published: September 2013

The thermal degradation of phenolic formaldehyde resins (PF) were studied using thermo gravimetric analysis (TGA). The evolved volatiles during thermal degradation of PF were examined by mass spectrometry (MS). The structure changes of thermal degradation of synthetical phenolic resin (PF1.2) and commercial resin (CPF) were investigated by solid-state 13C nuclear magnetic resonance (13C-NMR) techniques. The experimental results show that the degradation process of PF could be separated into three stages. In the first stage, ether bonds and unreacted terminal hydroxymethyl groups of the cured resin degraded. Methylene bridges decomposed into methyl groups then yielded both phenol and cresol homolog in the second stage. In the third stage, cyclodehydration and forming char of phenolic hydroxyl occurred. Our study showed that the main thermal degradation of PF in the second stage is the decomposition reaction of the methylene bridges instead of auto-oxidation of the methylene bridges reported in previous works.

Published: September 2013

Segmentation of brain magnetic resonance (MR) images is always required as a preprocessing stage in many brain analysis tasks. Nevertheless, the bias field (BF, also called intensity in-homogeneities) and noise in the MRI images always make the accurate segmentation difficult. In this paper, we present a modified FCM algorithm for bias field estimation and segmentation of brain MRI. Our method is formulated by modifying the objective function of the standard FCM algorithm. It aims to compensate for bias field and incorporate both the local and non-local information into the distance function to restrain the noise of the image. We have conducted extensive experimental and have compared our method with different types of FCM extension methods using simulated MRI images. The results show that our proposed method can deal with the bias field and noise effectively and outperforms other methods.

Published: September 2013

Nowadays, image fusion is one of the common color balance method. But, the color distortion is prone to occur in the fused image. To overcome such drawbacks, a novel method based on illumination correction was proposed in the paper. First, search the identical or similar ground objects areas on both source images, and calculate the average gray of each color component in the found areas. Then, calculate each color component ratio of the average gray of the reference image to the average gray of the color cast image, and take the ratio as the adjusting coefficients of corresponding component. Finally, each color component is multiplied by the adjusting coefficients separately. The theoretical analysis and experiment results show that the proposed method has better ability in color balance.

Published: September 2013

In wireless sensor networks, the disconnected network is an important and special one. Generally, the disconnected network is often characterized as a graph in graph theory. Suppose that edges fail independently of each other with equal probability and nodes are perfect. In this paper, a new reliability measure of disconnected network is proposed and defined as the probability that the edge-induced subgraph induced by surviving edges is connected. Different from traditional all-terminal reliability, this new reliability measure focuses on residual edge connectedness and is able to distinguish the reliability of two disconnected networks which are in the same class. Furthermore, the partial-star S is also proved to be uniformly best disconnected network under our proposed reliability measure in its class.

Authors: Ma Yue Huai , Zhang Bin , Zhang Wei , Xu Meng Xiang
Published: September 2013

In this paper, the subcarrier and power allocation problem for the orthogonal frequency division multiplexing (OFDM) cognitive radio network which coexists with the primary network is studied. A cognitive waterfilling (CWF) power allocation algorithm which based upon the classical waterfilling mechanism is proposed for the single SU scenario. As for multi-SU case, we present an efficient joint subcarrier and power allocation algorithm called MS-CWF algorithm. Simulation results show the effectiveness of the proposed CWF and MS-CWF algorithms.

This paper designed method for non-volatile data storage using MCU internal data Flash, certain data Flash sector is divided into multiple data partitions, different data partition storage data copies in different historical time, the current data partition storagethe latest copy of the data; In the data read operation, first calculate the latest data copying Flash storage location, then directly reads the address. In the data write operation, first judge if the data writing position is already erased, if not,write data in next partition, while copy the other data in the current partition to the next partition; if the write position has been erased, write data directly to the current partition. This method is similar to EEPROM data read and write, easy to operate, and give a simple application interface, and can avoid the sector erase operation, to improve storage efficiency, while increasing the service
life of the MCU's internal data Flash.

Location-Based Medium Access Control Protocol for Data Intensive Wireless Sensor Networks
Authors: Yang Guo Yan , Guan Xin , Li Yan Feng
Published: September 2013

The traditional CSMA MAC node simply blocks its transmission if the medium is sensed to be busy. Thus, it is inefficient in terms of the network throughput due to overcautious estimation of the interference. In this paper, we propose a novel location-aware medium access protocol for data intensive wireless sensor networks. In this protocol, the contending nodes make use of their location information to achieve the concurrent transmission of exposed terminal so as to reduce collisions and improve the overall performance. We evaluate it in terms of delay and throughput and compare it with S-AMC using simulations. Results show that the proposed MAC protocol can take advantage of the location distribution of nodes to improve the average throughput of the network, reducing data transmission delay, and effectively improving the efficiency and performance in data intensive wireless sensor networks compared to S-AMC.
