Ant Colony Algorithm for Upgrading and Expansion Optimization of Water Distribution System

China Rural Water and Hydropower (2006)

Gang Xu

The hydraulic network calibration model was established,with the objective of minimization of the squared sum of the differences between the calibrated and initial pipe friction resistance estimated,and a set of constraints determined from a sensitivity matrix.After the preferable network model was obtained,the upgrading and expansion problem of water distribution system was studied using the ant colony optimization algorithms and good results were obtained.

Application of AHP FSE Method in the Network Course Quality Evaluation

Procedia Engineering (2011)

Rubo Geng Gang Xu

In order to resolve a problem on the network course quality evaluation be affected by many complicated factors, combining with Analytic Hierarchy Process (AHP) and Fuzzy Synthetic Evaluation (FSE) is applied in it. Firstly, it makes a top-down analysis of the factors that affect the network courses and establishes a set of hierarchical factor structure with AHP. Then, it evaluates the single factor, including to determine the weight of each factor to decision-making with AHP and to calculate the influence degree of each factor with FSE. Finally, it gives a down-top comprehensive fuzzy evaluation until obtaining the final evaluation result. Its results showed that AHP FSE considered fully the factors' hierarchy and weight that affect the quality of network course. The Application of AHP FSE method can give an overall evaluation for the network course effectively.

Design of strong S-boxes based on spatiotemporal chaotic system

Gang Xu

A substitution box (S-box) plays an important role in cryptographic algorithms.The design of S-box using chaotic systems has attracted a great deal of attention in recent years.A new method for obtaining cryptographically strong S-boxes based on spatiotemporal chaotic system is proposed in this paper.The discretized Baker map and affine transformation are used orderly by an algorithm to shuffle the table generated by the spatiotemporal chaotic system.The cryptographical properties of these S-boxes such as bijection,nonlinearity,strict avalanche,output bits independence and equiprobable input /output XOR distribution are analyzed.The results of numerical analysis show that the S-box designed by this method can against several attacks and all the criteria for designing good S-box can be satisfied approximately.More strong S-boxes can be obtained by this method with the change of the original conditions or control parameters of the spatiotemporal chaos system.Furthermore,our approach is suitable for practical application in designing cryptosystem.

Multi-objective evaluation model for aviation ammunition maintenance quality

Gang Xu Rubo Geng Mingcong Ma

Aiming at the uncertain information in the multi objective assessment for aviation ammunition maintenance quality, the model adopts the deviation degree of the interval number to determine the attribute weight, and uses WAA operator to obtain the comprehensive attribute value of the scheme. According to the possibility matrix, it gains the sequencing vector, so as to get the assessment scheme. The final calculation cases show the feasibility & reliability of the model. Under the circumstance that the weight is unknown, the model carried out the assessment for many schemes. The multi-objective evaluation model can effectively solve complex problem for evaluation of aviation ammunition maintenance quality in uncertain condition, and can provide the scientific support for the aviation ammunition maintenance decision.

Condition monitoring of reciprocating compressor using FBG-based sensors in petrochemical industry

Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE (2012)

Yutang Dai Gang Xu Xiaodong Niu Qiuming Nan Minghong Yang

Real-time, on-line measurement of key physical parameters as well as their variations is the most crucial problem for safety running of reciprocating compressors in petrochemical plants. In this paper, a method for condition monitoring and fault diagnosis of reciprocating compressor based on FBG sensors is proposed. A fiber optic accelerometer is demonstrated, which is used for detecting the vibration of crankcase, crosshead and cylinder of the compressor. FBGbased temperature sensors are used to monitor the variation of the suction/vent valve temperature. A monitoring system included hardware and software for the reciprocating compressors is developed and applied in a petrochemical plant.
