Compared with other indoor localization technology, Ultra-wide Band (UWB) has the advantages of high precision, strong communication ability, wide coverage and convenient deployment, etc. As a result, UWB is a very popular solution for most indoor positioning applications. However, the performance of UWB signal is susceptible to several factors, among which Non-Line-of-Sight (NLOS) propagation is...
Bayesian network is able to make full use of prior knowledge and finite sample data. Due to the characteristics of being hard to be quantized,this paper models one specific insurance operational risk-fraud risk with bayesian network by establishing the topology and determining the value of nodes and parameters. It manages to analyse fraud risk by probabilistic inference ability of bayesian network,which...
Anchored in the new understanding of urban transportation system and aimed at the characteristics of the old urban area, the necessity of developing bicycle transportation in old urban areas was analyzed from the perspectives of enhancing general city image, protecting and developing cultural relics, promoting tourism industry, enlarging road network capacity and facilitating the trips of bicycle...
In order to scientifically and accurately forecast urban rail transit passenger flow and reduce it's risk, it is necessary to analyze the sensitivity factors of urban rail transit passenger flow, based on which a sensitivity analysis can be done. Based on the generation mechanism for the passenger flow of urban rail transit, this paper analyzed the sensibility factors that have an impact on the passenger...
The fluorescence spectra of the solutions of industrial color Sudan IV are measured experimentally, excited by 345nm light. A wavelet transformation-radial basis function neural network is established, using the spectral data, to determine the concentrations of the Sudan IV solutions. The relative error turns out to be 0.73%. Meanwhile, the spectra of six synthetic food colors Ponceau 4R, Amaranth,...
We use the study method of Computational Finance to explore the formation and evolution of asset prices from the standpoint of the evolution of investor individual's heterogeneous behavior through building an agent-based artificial financial market. In our model,agent will consider fundamental information and price tendency simultaneously at each period to form expectation that based on personal characters,...
In this paper, the mathematical functional model of the optimized baseband symbol signals is established in accordance with the criterion for minimized out-of-band energy radiation. The functional is limited with the restrictions on conditions of boundary, single baseband symbol signal energy and constant envelope. With the introduction of Legendre series, the baseband symbol signals with optimized...
The water quality computer simulation is an important method to study the water flow field and the change of water quality in lake. In this paper, combining two-dimensional shallow water dynamics-water quality model with FLUENT software to simulate the water quality of Daming Lake in Jinan. The results can reflect effectively the changes of water flow and water quality of Daming Lake in actual situation,...
The use of virtual reality (VR) techniques in industry is subject to very high expectations, as VR has emerged as a popular technology for computer-human interfaces in order to master the shortcomings of CAD/CAE systems.3D CAD models provide a natural way of sharing design information among participants in the production process. VRML is a tool specifically designed for creating 3D virtual worlds...
Objective To evaluate the adsorbing effect of montmorillonite on uric acid and montmorillonite decreasing the level of uric acid in the serum. Methods The adsorbing effect of montmorillonite was observed in vitro and the effect of decreasing the serum concentration of uric acid of acute hyperuricemia model mice. The concentration of uric acid was measured by a method of uric acid enzyme and enzymatic...
