Interpretative Structural Modeling (ISM) is an effective approach to analyze the complex system structure. The adjacency matrix represents the relations between and among system elements and the system digraph can be drawn by deduction of the reachability matrix. The adjacency matrix is usually built by experts' experience. Because the process does not take the corresponding data of system elements...
Radio Frequency Identification (RFID) has a widespread application in reality, and RFID wireless network planning is a core challenge in the deployment of RFID networks. This paper presents a new approach for optimal scheduling of RFID network based on our proposed MCPSO algorithm. RFID network planning problem is identified as a graph partitioning problem by mapping the readers in RFID network into...
Strict Integrity Policy (SIP) of Biba model can maintain the integrity of computer systems, but it might decrease the compatibility of applications. An improved SIP with dynamic characteristics based on the subject's history behavior is presented. The improved policy has been applied to OpenID, which shows that it can improve the compatibility of the system while keeping the integrity as strict as...
Network application cooperation fair congestion control (NACF) method is proposed for Internet congestion control. The basic idea of NACF is the coordination between network and application. The core mechanisms are hierarchical rate coding and dropping algorithm in network and the flow control by analyzing the acknowledged packets with rate code in application. the basic algorithm is introduced and...
Cloud computing is the development of parallel computing, distributed computing and grid computing. It has been one of the most hot research topics. Now many corporations have involved in the cloud computing related techniques and many cloud computing platforms have been put forward. This is a favorable situation to study and application of cloud computing related techniques. Though interesting, there...
The structure of the multi-point Fiber Bragg Grating (FBG) temperature measurement system is presented in this paper. It uses the wavelength demodulation method which applies In GaAs detector array to measure the light intensity to monitor the situation of the seepage in the dam. According to the laboratory data, analyze the possibility of the multi-point fiber grating sensor system and the reliability...
Structural random vibration effective information extraction is one of the most important issues to study the dynamic characteristics of engineering structures. Combined with singular entropy theory, an effective method of noise reduction for random vibration signal is put forward. Construct analog signal with varying degrees of noise, and the noise is reduced based on the wavelet method, IIR numeric...
In order to suppress undesirable noises in triangular meshes for quality improvement, an effective smoothing method based on curvature flow is proposed in this paper. For triangular meshes generated from planar contours, the continuity information amongst adjacent contours is utilized to determine whether a vertex represents a geometric feature to preserve or an isolated noise to smooth. Before smoothing...
The article analyzes the new opportunity for the agricultural e-commerce which was provided by the third land reform. Meanwhile, it also points out the shortcomings of the present practical teaching in e-commerce undergraduate education ,and creates the new mode of integrating the undergraduate practical teaching into the agricultural e-commerce from the perspective of considering e-commerce as the...
Teaching-Aided Website (TAW) is a complex social technical system. As a result, the evaluation on TAW's service quality (SQ) is a complicated social process. The paper analyzes the characteristics of college TAW. Then it designs the evaluation index system and approach for measuring the Website's SQ. AT last, it gives the process and result of the case study on a college TAW. The data indicate that...
Emergency Response Organization is the foundation of the emergency response, it is also important for emergency handling. However, since emergency systems are different in different countries and regions, the expressions of emergency response organizations are inconsistent, and there are some semantic ambiguities. An emergency response organization Ontology model (ERO2M) based on SUMO was constructed...
