The single-chip microcomputer course is a strong theoretical and practical course. By the analysis on the current problems existing in the single-chip microcomputer teaching process, the current teaching methods are unfavorable to the cultivation of learner's personality and innovative talents. Flipped classroom can transform the students' passive learning to active learning, so it is completely necessary...
This paper proposes three dimensions of characteristics to describe the shock load, including reactive power, time, rate of change, then established the simulation model to did deep analysis on the impact of the voltage quality problem for shock loads connected into distribution network, it focuses on comparing the different dimension characteristic due to the difference of the impact of the voltage...
With rapidly analysis, no pollution, no damage, simple operation, low analysis cost, environmental protection and many other advantages, the near infrared spectroscopy (NIR) analysis has made breakthrough progress in the Chinese medicine field. In this paper, the near infrared spectrometry of extract of two kinds of astragalus is determined. Wavelet transform is used to compress the spectral variables,...
A number of researchers focus their research on spectrum sensing technologies. Single-node spectrum sensing algorithms and fusion-decision algorithms in cooperative spectrum sensing are proposed from different special aspects to get better network performance. This paper analyzes these performance influence factors of these algorithms, including SNR, cognitive user number, and so on. Simulation and...
The current study of Internet topology measurement is mainly based on trace route which brings the problem of sampling bias. This paper makes a model of the sampling process, and analyzes the bias of node degree in sampling probe. We find that the probe based on trace route less impact on the degree distribution of nodes. Simulation shows that the curves of degree distribution sampled from probe source...
Anonymous Router (AR) is a key issue of Network Topology. Aiming at the deficiency of previous research, this paper proposes an AR network model based on DM model and quantitatively analyzes the influence on the result of probing by computing network size, node degree distribution and network path length. The conclusion is the existence of AR will affect the sample network, so single-source and multi-source...
As a high precision measurement displacement sensor, Grating-Ruler has been used widely. In this paper, we present a method which combines FPGA (XC3S100E) device, hardware description language (Verilog) and EDA software (XILINX ISE) to deal with the output signal from Grating-Ruler. The whole processing is made of three parts: signal preprocessing module, subdivided and direction-judgement module,...
The proposed complex logistics system is the theoretical innovation of supply chain management, Its research is still in the initial stage. Based on previous studies, this paper will continue to explore the concept, characteristics and structure of complex logistics system in theory; in application, sum up the characteristics of complexity simulation software Vensim, analyze the feasibility of using...
The logistics distribution's costs account for the proportion of the total cost of logistics is the highest, and its rationalization will bring tremendous business benefits. This paper uses system dynamics theory, Firstly, conduct the system boundaries analysis and causality analysis, build out of the system dynamics model and the equations , which will be closer to reality; then combines the case...
To solve the multi-objective optimization problem of material selection, analysis hierarchy set pair model integrating analysis hierarchy process with set pair analysis is presented. Firstly the hierarchy recursive structure was constructed in the model. Secondly the relative closeness was used to evaluate material properties. At last with hierarchy synthesis weight modified the relative closeness...
