Thorough summarizing the earthquake damage of the towns and villages housing, and the reason why the traditional ring beam and constructional column are difficult to implement in town buildings, the seismic techniques of fabricated constructional column and ring beam was proposed for different intensity area. The ring beams and constructional columns are characterized by the special lining made of prefabricated blocks. The traditional ring beam and constructional column technology based on cast-in-place should be replaced by masonry construction technology (or part casting but not need support mold). It will be a simple means to improve the seismic capacity of village structure but not to increase the cost of the housing. © 2011 IEEE.

Based on Lyapunov stability theorem, a MRAC system was researched to solve that differential value of plant output is unknown. Meanwhile an improved design for MRAC system aimed on the factor of restricting convergence of system is given. The method not only solves the problem that makes the system cannot work well as a result of the adjustable parameters, but also improves the convergence of plant. The simulation graphs have shown that the plant can follow the output of the reference model quit well. © Springer Science+Business Media New York 2014.

Journal of Software 2011年第6期6卷 1001-1008页

作者： Ji, Zhanlin Ganchev, Ivan O'Droma, Máirtìn College of Computer and Automatic Control Hebei United University China Telecommunications Research Centre University of Limerick Ireland

This paper describes the design and implementation of the advertisement data management and corresponding intelligent application for use in wireless billboard channels (WBCs) services in the emerging ubiquitous consumer wireless world (UCWW). Running at the application enabler sub-layer of a WBC service provider (WBC-SP)'s node the advertisement data is formatted by using the abstract syntax notation (ASN.1) and organized into segments to reduce the access time, and thus minimizing the mobile terminal's (MT) energy consumption on this service. The intelligent application is implemented within three tiers of the WBC service layer: a service discovery and maintenance tier acting as a client-server distributed system for data collection and organization;an intelligent application tier holding all business logic and common application programming interfaces (APIs);and a multi-agent system (MAS) tier maintaining the advertisement, discovery and association (ADA) agents' lifecycle, and supplying directory facilitator services and message transport services. The performance evaluation of the proposed data management scheme is performed. Details of the application's architecture are also provided. © 2011 ACADEMY PUBLISHER.

Studying the infrared spectrum absorption characters of SO 2 and CO 2 in middle infrared region, we have found that the band which CO 2 effects the measure result of SO2, and mathematical model is established which is to erase the cross disturbance of CO 2 . The O 2 concentration detection device of single light-four detectors is designed to measure the concentrations of SO 2 and CO 2 respectively by two pairs of light filters and detectors. Fitting curve equation between SO 2 and CO 2 are gained by experiment data fusion. This method overcomes deficiency of single measure method, erasing the influence of CO 2 on SO 2 measure precision efficiently. Thus, an effective method is found to analyze infrared gases.

The algorithm for the association rules of data mining is updating and reforming, and more and more algorithms are present now. Most of the algorithm evaluations make advances only from some aspect, which makes the users select difficultly. In this study, we apply the AHP (Analytic Hierarchy Process) to the comprehensive evaluation of algorithm, by which the subjective and objective evaluations could be combined to comprehensively evaluate the algorithm and help the users find out the most suitable algorithm.

Software-Defined Networking (SDN) represents a significant shift in network architecture, providing exceptional programmability, flexibility, and simplified management. However, this paradigm shift introduces a unique set of security challenges that must be addressed to fully realize the potential of SDN. This paper examines the security issues in SDN environments, detailing the threats and vulnerabilities at various layers of the SDN architecture, including the control plane, data plane, and application plane. Through an extensive review of current literature, critical security challenges such as controller attacks, data plane breaches, and vulnerabilities in inter-plane communications are identified. Existing security solutions and mitigation strategies, such as authentication and authorization mechanisms, encryption techniques, and intrusion detection systems, are also explored. Furthermore, the paper discusses recent advances and emerging trends in SDN security, offering insights into ongoing research and future directions. The findings underscore the importance of robust security measures in ensuring the reliability and integrity of SDN deployments, providing a foundation for future innovation and development in this dynamic field. © 2024 IEEE.

Aiming at the complexity of hydraulic vibrancy platform, a PID control method of double closed loop control based on IMC control principle is put forward. It realized the proportion control in inner loop using the anti-interference of the PID control, and the controlled object was transformed into a one-order inertia link with the time-delay unit. After approximating the time-delay unit by the 1/1 Pade method, the low pass filter and PID controller that they are equivalent to IMC controller can be obtained by using IMC control principle to realize outer loop control. Listing some material steps at designing of IMC controller, through the simulation experiment, it shows that the IMC-PID control method is superior to the traditional PID method in anti-interference and robustness, and its application value in projects is very high.
