Melamine Analysis in Liquid Milk by Simple and Robust Neural Network Based Method

By Sergey V. Smirnov

DOI: https://doi.org/10.5815/ijeme.2011.03.04, Pub. Date: 29 Sep. 2011

Melamine (2,4,6-triamino-1,3,5-triazine) is a nitrogen-rich chemical implicated in the pet and human food recalls and in the global food safety scares involving milk products. Due to the serious health concerns associated with melamine consumption and the extensive scope of affected products, rapid and sensitive methods to detect melamine’s presence are essential. We propose the use of spectroscopy data – produced by near-infrared (near-IR/NIR) and mid-infrared (mid-IR/MIR) spectroscopies, in particular – for melamine detection in complex dairy matrixes. It was found that infrared spectroscopy is an effective tool to detect melamine in liquid milk. The limit of detection (LOD) below 1 ppm (0.76±0.11 ppm) can be reached if a correct spectrum pre-processing (pre-treatment) technique and a correct multivariate (MDA) algorithm: partial least squares regression (PLS), polynomial PLS (Poly-PLS), or artificial neural network (ANN) – is used for spectrum analysis. The relationship between MIR/NIR spectrum of milk product and melamine content is non-linear. So, non-linear regression methods are needed to correctly predict the triazine-derivative content. It can be concluded that mid- and near-infrared spectroscopy can be regarded as a quick, sensitive, robust, and low-cost method for liquid milk analysis. The technique can be applied for the automation of milk analysis.

Performance Analysis for Heterogeneous & Reconfigurable Computing Based on Scheduling

By Yiming Tan Guosun Zeng Shuixia Hao

DOI: https://doi.org/10.5815/ijeme.2011.03.05, Pub. Date: 29 Sep. 2011

Right now, heterogeneous & reconfigurable computing is a research hot in the area of high performance computing. Due to the heterogeneity of application tasks and reconfigurability of system architecture, performance analysis for heterogeneous & reconfigurable computing becomes rather difficult. Unfortunately, the existing techniques and methods are no longer suitable for use. This paper presents a performance analysis method based on task scheduling. It builds on system architecture model and task model of heterogeneous & reconfigurable computing. By making use of heterogeneity matching matrix and reconfigurability coupling matrix we achieve optimal selection and matching between computational tasks and processing units. Through task scheduling algorithm, the completion time of application task run on heterogeneous & reconfigurable computing system can be calculated. Finally, we carry out case study.

Construction of Cisco Virtual Lab Platform

By Gang Zhang Jiajian Yin Xiaomin He Qinling Zhong

DOI: https://doi.org/10.5815/ijeme.2011.03.07, Pub. Date: 29 Sep. 2011

In experiment of network engineering and network construction, students are required to configure Cisco network equipment. Due to limit of lab environment, amount of equipment is not enough and some experiments require much more expensive and higher level equipment that are not practical to purchase and maintain. It is meaningful to use network equipment simulator on PCs. The proposed platform utilizes Dynamips simulator to simulate routers and switches of Cisco product series. Dynamips supports directly loading Cisco IOS images and provides configuration interface as true equipment’s. It has very good teaching effect in experiment of network engineering. And success of the proposed platform shows it can be used in other network related courses.

Binary Encoding Differential Evolution for Combinatorial Optimization Problems

By Changshou Deng Bingyan Zhao Yanlin Yang Hai Zhang

DOI: https://doi.org/10.5815/ijeme.2011.03.09, Pub. Date: 29 Sep. 2011

Differential Evolution algorithm is a new competitive heuristic optimization algorithm in the continuous field. The operators in the original Differential Evolution are simple; however, these operators make it impossible to use the Differential Evolution in the binary space directly. Based on the analysis of problems led by the mutation operator of the original Differential Evolution in the binary space, a new mutation operator was proposed to enable this optimization technique can be used in binary space. The new mutation operator, which is called semi-probability mutation operator, is a combination of the original mutation operator and a new probability-based defined operator. Initial experimental results of two different combinatorial optimization problems show its effectiveness and validity.

Research and Application of Blended Learning in Distance Education and Teaching Reform

By Chen Haijian Huang Hexiao Wang Lei Chen Weiping Ju Kunru

DOI: https://doi.org/10.5815/ijeme.2011.03.10, Pub. Date: 29 Sep. 2011

The new learning method of "Blended Learning" is widely applied. It integratess two typical forms of traditional classroom teaching and online teaching. How to unify them effectively? We explored the blended learning model .In the course of "Basic Program Design" we made an attempt for two years by using the example of teaching practice. We emphasized on the rates of attendance, including attendance in classroom and studying records on E-Learning. Student performance in classroom was recorded and immediately uploaded to E-learning platform. The teaching effectiveness was evaluated by thoroughly disserting in every detail of teaching, etc. Through the contrast, the quite good effect was obtained. This was the initial attempt to reform the learning model. In the future of teaching career, the effectiveness of blended learning model will be further explored in different courses.

By Gao Guibing Huang Gang Zhang Guojun

DOI: https://doi.org/10.5815/ijeme.2011.03.12, Pub. Date: 29 Sep. 2011

An improved multi-objective evolutionary algorithm with the hybrid strategies is presented in this paper for multi-objective optimization problems. The evolution process is divided into initial exploration stage, the middle feedback stage and the accelerating convergence stage by the amount of non-dominated individuals in the population. The hybrid strategies and adaptive population structure are employed to improve the behavior of the algorithm at the different stages. The proposed algorithm is validated by 3 benchmark test problems. Compared with three other famous multi-objective algorithms by two quality indicators, the proposed algorithm achieves competitive results.
