Abstract: In this paper, the framework and subsystem detailed design of LSSIMS (Large Sport Stadium Information Management System) is proposed on the basis of main function-demand analysis. After the main function demand is analyzed under 6 iterative stages, the overall framework design of the system is proposed on the basis of the principles of frame design. Then the LSSIMS is divided into the subsystems including the gateway websites, ticketing business subsystem, fitness management subsystem, online interactive subsystems, commercial operation subsystem and advertisement management subsystem. Finally the subsystems are designed individually by adopting the middleware technology and the thought of multi-level, loosely coupled and open design. Through the later stages of detailed design and full system development, it is showed that based on the framework design the LSSIMS provides managers with detailed statistical analysis, decision support and standardization interfaces, which can make good social benefits.

Abstract: An upstream transmission scheme of asymmetric clipping optical orthogonal frequency division multiplexing (ACO-OFDM) based WDMA-PON is proposed. Performance of 10Gbit/s/ONU upstream ACO-OFDM signal is analyzed. The scheme is high capacity and power efficient.

Abstract: The problem of robust stabilization for a class of SISO uncertain nonlinear Differential-Algebraic Eqyatuion subsystems is considered in this paper. The robust stabilization controller is proposed based on backstepping approach using two-layer Artificial Neural Networks (ANN) whose weights are updated on-line. A new adaptive algorithm is proposed to update the weights of ANN such that all signals in the closed-loop systems are bounded and the states are convergent asymptotically to the equilibrium through the proposed controller.

Abstract: This paper aims to solve the problem of stabilization about a switched affine system with stable and unstable subsystems. We show that if the switching signal satisfies the so called average dwell time approach, the uniform stabilization of the switched affine system under specific switching signal is guaranteed with explicit bound, and the switched autonomous system is a special case which is asymptotically stabilization. Then, we applied this result to Dc-Dc converters; the results verify that the peak-current control boost is uniform stabilization. Simulate results verify the theoretical analysis. The proposed Theoretical analytical methods can apply to other Dc-Dc converters under specific switching signals.

Abstract: Based on background, taking the engineering construction material information management system to replace the traditional artificial management mode in recent years has caused extensive concerns in the construction enterprises. Then, this paper used .NET technology to implement the construction material information management system.

Abstract: Ecological security is the basis of the sustainable development. Based on the concept of ecological security, The framework and subsystems’ functions of decision support system for mining area’s ecological security are put forward. The support system, which gets data by methods of remote sensing(RS),geographical information system(GIS),global positioning system(GPS), survey data, statistics data and experiment data, being mainly composed of database management system, knowledge management system and models management system, can make regulating and controlling decision for mining area’s ecological security.

Abstract: With the continued expansion of logistics business, and the growing number of network node, enterprises scale will be expanded, including: business department, offices, and even branches, as well as multi-level agents, partners and so on. Conducting business in this complex interwoven network, the logistics business appears to be inadequate in the ways of business, finance, management. This paper provides the modern integrated logistics management platform with a set of comprehensive globalization solutions.

Abstract: Logistics has been an integral profit source of modern social economy due to the booming Logistics industry & service. Logistics Management Information System (LMIS) has been created as integrated information system in response to the calling for the requirement of advanced technology to organize and process the information accompanied during Logistics operation for efficiency and smoothness of Logistics management and business process. This thesis comes up with a LMIS plan suitable for Logistics industry development by carrying out detailed analysis of present situation of management and further research on LMIS.

Abstract: This paper proposes an experimental method for obtaining the Frequency Response Function (FRF) between a dynamic force and the signals emitted by a piezoelectric dynamometer. This function is known as Transmissibility. In the FRF obtaining stage, different configurations of mounting and excitation have been compared to improve the function quality. The method has been developed with a three components dynamometer fixed on a milling machine. The FRF has two principal applications: it is used to evaluate the measurement system accuracy and to correct the measurements, if necessary. The method has been developed with the purpose of studying the cutting forces in machining process. Furthermore, it has been identified the influence of the parts of the measurement chain in the measuring system response.
