Authors: Lin Jeng Jong
Published: September 2013

A unit cell of geometry model is applied to acquire the material matrix of the woven fabric in the study. The softness of woven fabric is related to the flexure modulus, which can be obtained from the acquired material matrix. Two sample fabrics are employed to verify the relationship between the softness and the flexure modulus. It reveals that the results are quite promising as expected. An intelligent support system for determining the softness of the fabric based on flexure modulus can thus be implemented in the future. Through the assistance of the system, the softness for different fabrics can be evaluated without any sample fabrics manufacturing in advance. A designer can determine the softness of a piece of fabric without proceeding with the traditionally essential procedure of sample manufacturing. The goal to increase the design efficiency of innovative woven fabric can thus be achieved.

Authors: Lin Jeng Jong
Published: September 2013

The aim of this study is focused on development and presentation of an intelligent system with a searching mechanism based on GA and an evaluation mechanism based on SAM geometrical model to help a designer design various expected innovative textile product. The search mechanism can efficiently find many manufacture solutions for the fabric, after each of which being evaluated by the evaluation mechanism, there an optimum (or approach to optimum) solution can be obtained. The system can facilitate the fabrics designer to obtain the best combination of weaving parameter during the elastic properties of the fabric (i.e., Young's modulus) being taken into consideration in design. Besides, the system can figure out the other essential characteristics, e.g., the fractional cover and the weight per area (g/100 cm2) of the fabric manufactured by each set of surveyed solution to provide the designer with selections of the functionality of the developing woven fabrics. Through the assistance of the intelligent system, it can become more efficient for a designer to directly idealize his (her) design concept without any sample manufacturing beforehand in a textile product designing. The textile material genome initiative can thus be approved and fulfilled in the near future.

Authors: Zhang Wei , Wang Han Hu , Li Hui
Published: September 2013

In high-dimensional index, overflow split has been verified to be critical to the performance of kNN query processing. A node is split into two parts in the traditional way, however, these methods tend to result in many overlap regions in high-dimensional spaces which will significantly degrade the performance of retrieval. In this paper, we propose a method named KSR-Tree, it making use of a clustering based split algorithm to divides the node into multiple parts, and most of overlap regions will guarantee to be placed into the same node. This approach not only increased the capacity for newly arrived records, but also decreases the splitting overhead and reduces the overlap regions, thus the frequency of node splitting will reduced and meanwhile the retrieval performance obtains improvement.

E-MsNFIS: Efficient Negative Frequent Itemsets Mining Based on Multiple Minimum Supports
Authors: Xu Tian Tian , Dong Xiang Jun
Published: September 2013

Negative frequent itemsets (NFIS) like (a1a2¬a3a4) have played important roles in real applications because we can mine valued negative association rules from them. In one of our previous work, we proposed a method, namede-NFISto mine NFIS from positive frequent itemsets (PFIS). However,e-NFISonly uses single minimum support, which implicitly assumes that all items in the database are of the same nature or of similar frequencies in the database. This is often not the case in real-life applications. So a lot of methods to mine frequent itemsets with multiple minimum supports have been proposed. These methods allow users to assign different minimum supports to different items. But these methods only mine PFIS, doesn’t consider negative ones. So in this paper, we propose a new method, namede-msNFIS, to mine NFIS from PFIS based on multiple minimum supports. E-msNFIScontains three steps: 1) using existing methods to mine PFIS with multiple minimum supports; 2) using the same method ine-NFISto generate NCIS from PFIS got in step 1; 3) calculating the support of these NCIS only using the support of PFIS and then gettingNFIS. Experimental results show that thee-msNFISis efficient.

Authors: Yang Yu , Xiao Zhang , Shuai Wang , Rui Meng , Wang Chao Wei
Published: September 2013

In this paper, we investigate Device-to-Device (D2D) communication underlaying cellular networks to provide spectrally efficient support of local services. Since in underlay mode, D2D communications share resources in the time and frequency domains with cellular system, it will introduce potentially severe interference to the cellular users and accordingly presents a challenge in radio resource management. In order to avoid generating interference to the high-priority users (cellular users) operating on the same time-frequency resources and to optimize the throughput over the shared resources under the transmit power and the quality of service (QoS) constraints, we propose an interference alignment-based resource sharing scheme for D2D communication underlaying cellular networks.

Interference-Aware Routing and Power Control Joint Optimization in Hybrid Wireless Networks
Authors: Zhao Li
Published: September 2013

In this paper, we optimize the routing and transmission power in hybrid wireless networks based on an interference-aware criterion. In particular, we consider a hybrid network consisted of a base-station (BS)-oriented network and a device-to-device (D2D) system cooperatively working on the same spectrum. Firstly, we formulate the joint optimization problem which aims to minimize the expected network cost for package delivery. Secondly, in order to analyze the relationship between the transmission power and the link cost, we develop a novel cost model considering the interference impact. Then we propose an efficient algorithm to solve the optimization problem. Finally we simulate the proposed scheme in the hybrid network based on LTE. The result shows an improved overall throughput, and demonstrates that the proposed scheme could well solve the compatibility problem of two wireless networks.

Authors: Gao She Sheng , Zhao Yan , Wei Wen Hui
Published: September 2013

This paper presents a fuzzy anti-interference transfer alignment method for airborne strapdown inertial navigation system (SINS). This fuzzy anti-interference transfer alignment method takes the influence of systematic error into account for SINS transfer alignment. The fuzzy rules are constructed and incorporated in the filtering process to estimate the covariance matrices of observation vector and predicted state vector with random weight method. The experimental results demonstrate that the proposed method can resist the interferences caused by the airborne maneuvering process, thus improving the accuracy for SINS transfer alignment.
