BLP model is a classic model of significant strategies of confidentiality. By classifying and marking the subjects and objects, it realizes the discretionary access control and mandatory access control. Existing system security models are mainly based on the improved BLP model. Along with the popularity of mobile devices, cross-platform system based on Web is attracting more and more attentions. For...
In this paper, we present a framework for automatically analyzing activities and interactions, and recognizing traffic states from surveillance video. Activities and interactions are firstly learned by Hierarchical Dirichlet Process (HDP) models based on low-level visual features. Based on the learning results, a Gaussian Process (GP) classifier is trained to classify the traffic states in online...
For instance the evaluation of an Olympic problems in this paper, Firstly we collected statistical data of various factors through the establishment of the model of grey relational degree. Then quantitative analysis using the model of these factors impact on the evaluation of the object and come to affect the degree of ranking. The use of a wide range of the models in agricultural economics, water,...
This paper gives a method and finally gets twelve marketing risk assuming factors based on 35 middle-sized Communications and related equipment manufacturing enterprises by statistical methods like PCA, D-S evidence theory, and fuzzy evaluation. Then we build marketing risk assessment model by probabilistic reasoning model based on Bayes network. Also there is an example to prove the method's feasibility...
A novel visual attention model using multi-scale cues is presented in this paper. Visual data is decomposed into multi-scale sub-images which contain multi-scale details on the basis of Gaussian Pyramid, and contrast features are extracted from these multi-scale images for saliency map generation. Compared with other visual attention models, the proposed model can efficiently generate saliency map...
Collision and redundancy problems in RFID system have attracted more and more attention. Collision problems have been studied intensively. However, redundant reader elimination problem is studied only recent years. In this paper, we study the simulation and analysis of algorithm RRE and algorithm TRRE (two-step redundant reader elimination), which are two algorithms used to eliminate redundant reader...
Work breakdown structures are the base for project management. The quality of work breakdown structures of automobile R&D project directly affects the control of the process of automobile new product development in time, cost, scope, quality and other aspects. In order to improve the quality of work breakdown structures, the paper introduces Plan-Do-Check-Action cycle and develops a distinct process...
The simulation of communication constellation for phase 0/A has a lot of uncertainty factors. Exploratory analysis faces high level system demonstration. By examining the consequence of uncertainty, exploratory analysis explores all kinds of abilities and strategies of the system, to grasp the essential factors and gain a broad understanding of problem domain before dipping into details. In the methodology...
