In this paper, the problem of estimating the motion and shape parameters from the infrared signature of precession object is addressed. To limit the scope of this work, only objects with shape of flat-plane, cone, cylinder, cone-cylinder combination are considered. Different from the current research, the parameter estimating is based on signal modeling. First, a signal model is proposed to approximate...
Cyberspace situation awareness (CSA) is the base of cyberspace operations (CO). A right decision of CO is based on the correct awareness of the cyberspace situation. The paper analyzes two classical models, and then takes account of the characteristics of cyberspace operations, finally proposes a hierarchical, multi-perspectives model. The model employs three perspectives and four layers. The model...
Transportation resources allocation of group enterprise is an important research issue. Based on the non-convex interval goal programming and the discrete resources ideology, this paper sets up three categories, eight basic models for the analysis of enterprise transportation resources allocation. These basic models could be modularly used in practice. Our research outcomes are consistent with the...
By emphasizing on the network marketing system, this paper analyzed Bsteel's e-business. On the basis of research findings, the paper listed some basic elements that should be included in a systemic performance evaluation system, and the mathematic model of this system. Consequently, we established an evaluating system for network marketing, and also made reasonable judgment of Bsteel's current performance,...
A multi-stage cooperation and competition model based on flexibility in port service supply chain consisting of a port enterprise and two service providers (SP) is built, using Stackelberg model and Cournot model. Flexibility in port service supply chain is studied. The influence factors of port enterprise's flexibility strategy and SP's flexibility strategy, relationship of port enterprise's flexibility...
Exposure of the biological cells to an external electric fields can cause the change of the transmembrane potential on the cells, leading to a variety of biochemical and biophysical change of the cells which can be evaluated by power dissipation. The second analytical models were derived to calculate the power dissipation within the cell membrane in high concentration suspensions exposed to DC fields...
