With the rapid increase in the number of integrated circuits I/O, the traditional wire bonding package has been unable to meet the high I/O number of interconnection needs, flip-chip process can undoubtedly solve the high I/O number of miniaturization package problems, especially flip-chip plastic package can fundamentally meet the increasing number of pins, improve speed and high frequency performance,...
Based on the traffic accident data of Beijing China in 2012, we combined with a variety of municipal administration data, used the geographically weighted regression (GWR) method to study spatial non-stationarity and heterogeneity of the traffic accidents, and analyzed the causes of space regional in traffic accident black spots. Experimental results demonstrated that: (1) The GWR model detects change...
Through the analysis for the current urban road network and the urban traffic control schemes, establish the model of the average of vehicle up-time in road network. Then, by use for reference thinking of natural selection of genetic algorithm improved the minimum value problem of particle swarm optimization algorithm. Hereafter, the model was optimized by the improved particle swarm optimization,...
The prediction model of existing human body composition based on measured bioelectricity has problems that include redundant influence factors and low prediction accuracy. To address these problems, this paper put forward a human body composition prediction model based on Akaike Information Criterion (AIC) and improved entropy method. First, combining with the AIC information principle, we selected...
In this paper, we develop the max-margin similarity preserving factor analysis (MMSPFA) model. MMSPFA utilizes the latent variable support vector machine (LVSVM) as the classification criterion in the latent space to learn a discriminative subspace with max-margin constraint. It jointly learns factor analysis (FA) model, similarity preserving (SP) term and max-margin classifier in a united Bayesian...
Unsupervised multilayered (“deep”) models are considered for imagery. The model is represented using a hierarchical convolutional factor-analysis construction, with sparse factor loadings and scores. The computation of layer-dependent model parameters is implemented within a Bayesian setting, employing a Gibbs sampler and variational Bayesian (VB) analysis that explicitly exploit...
In order to establish the perceptual function model of products, we use image semantics words to express the perceptual capabilities of CNC machine tools in the study of their image modeling design. Consider the complexity of the image information, users tend to use a relatively vague image word to express their expectations of the product, however, due to the ambiguity and uncertainty of the image...
The general definition and operational characteristics of distributed generations (DGs) and micro-grid are summarized in this paper. Three technical requirements are proposed to achieve the most reliable interconnection between micro-grid and the external grid. A typical analysis model of micro-grid containing wind power generation and photovoltaic generation is built and simulated based on EMTDC/PSCAD...
At present, in the design for CNC machine tools, the method of separately considering the form and color is adopted. And these two factors can affect the modeling style simultaneously. In view of the above problem, according to the characteristics of modeling design for CNC machine tools, based on the theory of kansei engineering, this paper obtains the form, color and semantic quantitative description...
Based on the ideas of modeling of complex systems from “dynamic graph”, the analysis and design of dynamic topological structural coordinator was presented to remedy the model deficiencies that the system can only be adjust in the condition of minor interconnected intensity caused by the restriction of dynamic connective stability during the design of dynamic interconnected coordinator. The necessary...
This paper used mixed logit model to predict credit risk of listed companies in China. In order to reduce the difficulty in dealing with the facts of correlation and multidimension of the financial indexes of listed companies and meanwhile to ensure that the data are not lost, we introduced factor analysis to the mixed logit equation and constructed a factor analysis mixed logit model. Fifteen factors...
The study is to develop a three-dimensional finite element model to study the disease related to lumbo-pelvic-femoral complex. The CT images from the first lumbar vertebra to the upper third of femurs of a 25-years-old healthy male were obtained. Triangle mesh model was generated using these images by Simpleware. Then the whole solid model were set up after repair and optimization in Geomagic. The...
Grid resource monitoring system should take charge of watching a large amount of heterogeneous resources and their usage state. The paper analyzes the disadvantages of the current grid resource monitoring framework, then proposes a new monitoring model GMF-BMA and discusses the communication among middle layer, infrastructure layer and sensor layer in details. A prototype implementation of the model...
An efficient topology analysis algorithm for power network simulation modeling was proposed. In this method, ldquoLink-Linerdquo was introduced into the graphic element library to connect two elements directly and avoiding forming the complex linked list. Correspondingly, a Link-Line based original topology description method is proposed, in this way, we can use the ldquonodes integrationrdquo algorithm...
Trust-based delegation authorization mechanism is regarded as an effective method for computational resource access in open dynamic environment. One important problem is how to apply more grain subjective trust control on delegation and authorization procedure. On this paper, the problem is probed and a trusted role based logic model on the semantic of attribution authorization mechanism is proposed...
The distance between vehicles measurement is the only factor in traditional car rear-end alarm system. An alarming model based on MAS(Multi-Agent Systems) and driver's behavior is proposed to address the above problem. It is composed of four different types of agent, interface-agent, features-extraction-agent, recognition- agent and alarm-agent, which can either work alone or collaboration through...
Customer choice behavior, to a certain extent, determines the different mode types of Internet service provided by Internet Service Provider (ISP). But this aspect is often neglected by a majority of researchers. This paper introduced a simple customer choice model in which the probability of customer choosing a type of services was the function of service subset provided by ISP and therefore, the...
For the purpose of a parallel process for large scale systems, a balance of each processor tasks distributed in large-scale systems has to be achieved, that is, subsystems of the system should have some kind of balanced structures after decompositions, or the dimensions of subsystems are of similar size. Based on block triangle decomposition, the coefficient matrix A of linear system state equations...
