A huge limitation of the correlation analysis in existing scatterer model is that the former model, only consisting of uniformly distributed scatterers, ignores the variability of complex scattering intensity in real situation. In fact, each part of the target has a different scattering architecture. Moreover, the scattering intensity of pinnacle or boundary scattering structure is an order of magnitude...
This paper focuses on the problem of detecting driver's changing lane, and gives a state machine model to analyze driving behavior. Firstly, three-axis accelerated velocity sensor is used to gather data, and then smoothing filtering method is made to process data. Secondly, a change rate of accelerated velocity is computed by using linear regression method, and vehicle's turning range and acceleration\deceleration...
Networked air defense fire control simulation system featured with complicated interactions, varied system structure etc, and is usually faced with some difficulties in its development, such as the low capability of model reuse, the lack of regulations for model development and inflexible modification of federation. To overcome the difficulties, a framework in hierarchy of networked air defense fire...
In this paper, near-infrared spectroscopy (NIRS) combined with discriminant analysis was used as a qualitative tool to distinguish Fructus forsythiae from different geographical origins by collecting and analysing the NIR spectra in the range of 12000-4000cm-1. NIR spectra were analyzed by two methods: clustering analysis and discriminant analysis. In the former, the second derivative and Norris smoothing...
An efficient evaluation index system and evaluation model is crucial for effectiveness evaluation of the air defense networked fire control system. This paper, based on pre-research for functions and characteristics of the system, put forth a comprehensive evaluation index system which includes four layers of index hierarchy. Aiming at the characters of some indexes, several evaluation methods are...
A Petri Net is a graphical and mathematical modeling approach used to describe the transition of states for an information system. This paper presents a novel technique to generating test cases using a Colored Petri Net (CPN) model. The state space of a model based on CPN provides a solid basis for test cases generation in a form that can be easily manipulated. This technique is based on three testing...
In view of the defect that the gray method can only predict the tendency approximately and artificial neural network can not predict the future tendency really, a new organic gray neural network model was proposed by the advantages of ARMA and rbf neural network. The neural network was trained to get the optimal structure of neural network. According to the dynamic law of one river water quality in...
At present, with the popularization of higher education and acceleration of college students every year, colleges and universities are increasing scale. Expansion of the scale for colleges and universities on the one hand, broadens the scope for development, on the other hand it also brings many problems, including the issue of the quality of teaching which is particularly prominent. Owing to the...
