The paper describes the necessity carrying out electronic commerce personalized services firstly. It constructed a electronic commerce personalized service model based on web mining and described in detail the basic design idea and functions. This will provide a certain theoretical basic and reference value to build a true electronic commerce personalized service platform.
This paper proposed a redirection scheme used in the broadband access network to optimize the transmission of p2p service. The excellent performance of the proposed scheme in decreasing the burden of the core network data is verified through the simulations with NS2.
Resource space model (RSM) is a normalized classification model that uses m-dimensional semantic spaces to share and manage various resources in a centralized manner. This paper explores how to use the idea of classification semantics to organize indexes of resources in a decentralized manner. We deploy RSM on a structured P2P topology HRing by two ID management methods. HRing is a ring-structured...
An new model-free adaptive controller (MFAC) is proposed, combining the single output TD (tracking differentiator) with the basic MFAC. The novel TD-MFAC method improves the capacity of anti-jamming because of the filter characteristic of the single output tracking differentiator. Furthermore, TD-MFAC method is compared with PID control method. The simulation results show the model-free adaptive control...
Loan risk is one of most important source of risk that our commercial bank face and it constructs the main part of risk management. So strengthening the measurement is of much significance to our commercial bank. Based on brief introduction of the theory of loan projects risk, considering the complexity of multi-objective decision of credit risk assessment in commercial bank, this paper builds a new...
This paper presents a road signs detection, recognition and tracking system based on multi-cues hybrid. In detection stage, the color and gradient cues are used to segment the interesting regions, and the corner and geometrical cues are used to detect the signs. A pseudo RGB-HSI conversion method without the need of nonlinear transformation is presented for color extraction. In recognition stage,...
Human resources are the primary resources of an enterprise. Personnel training can cultivate core competence and achieve the success. In view of the existing fuzziness and randomness in the training effect comprehensive evaluation, an index system, which comprises the first class indices such as training condition, training management and training effect, was put forward; and then a two stage fuzzy...
The strains of an arbitrary point on the resonator of the hemispherical resonator gyro are deduced under Kirchhoff-Lyav hypothesis. The force equilibrium equations of the thin shell element are established on the basis of the calculated strains. When the gyro is subjected to three-axis angular rates and angular accelerations, the inertia force is calculated and the border motion equations of the hemispherical...
