With regard to nonlinearity and uncertainty in information security risk assessment, and on the foundation of hierarchical structure of information security risk assessment, the paper proposed a model of information security risk assessment based on advanced D–S evidence theory. In terms of the extent of danger of various risk factors in the system, and through the advanced Dempster combination rule,...
High-resolution aerial camera needs to cache position controlling parameters and large amounts of image data, pointing at this issue, a SDRAM controller used in high-speed and large-capacity caching system is researched. Firstly, the necessity of caching image data in high-resolution aerial camera is explained. Based on the feature of the CMOS outputted data format and character of SDRAM element,...
Most existing test system for infrared focal plane arrays are dedicated, it costly and the application value are limited. A test method for infrared focal plane arrays is introduced in this paper, and test system includes driving circuit, control module, data acquiring and processing circuit, video synthesis module and the PC software based on LabVIEW is established, which measures the key parameters...
Harmony theory summarizes and abstracts the mechanism of social economic development. Using harmony theory to analyze the harmoniousness of virtual enterprise, it can realize the co-adaptation degree more between enterprises which compose to a virtual enterprise set and improve its success probability. Based on the methods in manufacturing information theory, taking regional small and medium-sized...
Currently, the traditional search techniques canpsilat meet peoplepsilas demand. Along with constantly improving the precision and recall ratio of search engine, the demand of personalized service becomes particularly outstanding. Intelligent search system of network manufacturing resource is a focused search engine which orients to network manufacturing resource. Meanwhile, the system includes personalized...
This paper divides the genotype into two parts: genetic information and culture information. The self-adaptive learning algorithm (SALA) to sustain and enhance the diversity of population is put forward. This paper also proposes a relative adaptation strategy (RAS) which provides opportunity for individual schemata which is potential and a redundant reproduction operator (RRO) that naturally improves...
This paper summarizes the present research status of automated design method for dynamic systems, investigates efficient method of fitness definition for automated design method of dynamic systems based on bond graphs and genetic programming. The automated design method based on Hungarian algorithm and genetic programming (HAGP) is proposed, and the statistic results of domain independent - an eigenvalues...
Networked manufacturing is a trend of manufacturing industries and application service provider (ASP) is its mainstream mode. In order to solve the current questions of networked manufacturing, grid technology was put forward as a feasible approach to reform the networked manufacturing system based on ASP; considering the characteristic of grid technology, a new design constructing manufacturing grid...
