This paper concentrates on the synthetic aperture radar(SAR) image position analysis of the missile-borne SAR platform's motion errors based on the general missile-borne SAR diving model. The general missile-borne diving model expanded from the classic side-look image model includes three-dimensional position and three-dimensional velocity and can be used describe the motion of the missile-borne SAR...
The paper introduces a new simulation system for training EWA Combat Service Personnel (EWACSP), which uses data mining technology on the massive accumulation training information for knowledge discovery. In the system, the model of cluster analysis is established. Using this model, the system provides a higher level training program and arranges much more reasonable training for each Combat Service...
As the Government's macroeconomic regulation and control means, finance plays a significant role, but finance bears some certain risks. How to manage and prevent this risk is directly related to the survival and development of the whole country. This paper focuses on the combined model application research, fiscal risk early-warning based on principal component analysis and BP neural network. The...
Service-oriented software engineering emphasizes the discovery and reuse of existing service resources and aggregate them to meet user needs. This paper proposes a service-oriented and process-driven approach to modeling variability in software product line. In this approach, variability analysis and modeling as a means, domain ontology model as a starting point, process ontology model as the center,...
Merger is a relatively rapid and convenient means for firms to expand and enhance competitive ability. The existing literatures take no account of the fact that therepsilas debt in most firmspsila capital structure, whereas take the object of M&A as to maximize the firm value change. However, the decision-makers should be the stockholders of both firms, thus the merger object is to maximize the...
