Examples

  • Simulation results demonstrate that at isr ( interference - to - signal ratio ) = 50db , the performance of the proposed receiver is almost the same as the receiver without interference
    計算機仿真表明,當(dāng)干信比為50db時,采用該方法的誤碼率性能與無干擾時的誤碼率性能基本吻合。
  • Phase - based optimal image thresholding can deal with poor contrast , high noise to signal ratio , complex patterns , and variable modalities in the gray - scale histograms , and it can obtain very good result
    該方法能夠很好的處理低對比度,高信噪比,內(nèi)容復(fù)雜以及多種形狀的灰度直方圖的圖像。
  • At first , this paper reviews the traditional currency crisis theories and the research on the early warning system ; thereby try to search for the crisis root and some important early warning indicator , and then basing on those and the kaminsky ' s early warning system of the currency crisis , i analyze statistically the thailand monthly data from 1992 to 2000 , seek the threshold of every early warning indicator , the adjusted noise - signal ratio and the early warning synthesis indicator , forecast the possibility of thailand happening the crisis in the coming 12 month with the month data in 2001 , and finally conclude that thailand would not happen the crisis in the coming 12 month
    首先本文對傳統(tǒng)貨幣危機理論和近期對貨幣危機預(yù)警的研究進(jìn)行了回顧，從而試圖尋找危機的根源和一些重要的預(yù)警指標(biāo)，在此基礎(chǔ)上，運用kaminsky的貨幣危機早期預(yù)警方法? ?信號分析法，對泰國1992 - 2000年年間的月度數(shù)據(jù)進(jìn)行了統(tǒng)計分析，求出每個預(yù)警指標(biāo)的閾值、調(diào)整后的噪音信號比以及危機預(yù)警的綜合指標(biāo)，進(jìn)而采用泰國2001年的月度數(shù)據(jù)對泰國未來12個月進(jìn)行危機預(yù)測，最后得出泰國在未來12個月內(nèi)不會發(fā)生危機。
  • Based on these models , a main - road traffic flow model with two speeds on one dimension is designed . this model simulate the situation of one road in the city , traffic lights placed on the crossing , using the computer simulation , firstly , in the case of synchronized traffic lights , we investigated the velocity and flow of the model when the initial density , the turning probabilities , the number of the traffic lights , the green to signal ratio and the period of the signal are changed , then we have advanced some meliorate measure to traffic flow ; secondly , in the case of the traffic lights " signal update delay in turn , we found the optimal matching between the period of the signal and the delay time of the traffic lights so as to the perfect velocity and the flow of the model are attained
    在此基礎(chǔ)上，建立了一維二速主干道模型，該模型模擬了城市交通中一條主干道的交通情況，在交叉口處設(shè)置紅綠燈，通過計算機模擬，首先，在交通燈信號同步更新的條件下，研究模型在改變車輛的初始密度、轉(zhuǎn)向概率、交通燈個數(shù)、紅綠燈信號的綠信比、紅綠燈信號周期等各種情況下主干道的速度、流量的變化，根據(jù)模擬結(jié)果提出一些改善交通的有效措施；其次，在交通燈信號依次延遲更新的條件下，研究模型在參數(shù)道路長、紅綠燈綠信比、交通燈個數(shù)、車輛的初始密度給定的情況下找到紅綠燈信號周期和延遲時間的最佳匹配使得主干道的速度、流量達(dá)到最理想的值。
  • First , author studies oppressive jamming technology of sar based on its system gain , analyses its fundamental theory and jamming mechanism , programs an integral simulation software which produces noise data of several kinds , at the same time carries out many simulation experiments under different noise - to - signal ratio of each noise type , then makes in - depth analysis and comparison on those images resulting from simulation experiments and summarizes some conclusions of theoretical and practical value
    作者首先在分析合成孔徑雷達(dá)系統(tǒng)增益的基礎(chǔ)上研究了壓制性干擾技術(shù)，分析其基本原理及干擾機制，編制了一個完整的干擾仿真軟件，產(chǎn)生多種類型的噪聲數(shù)據(jù)，針對每種噪聲類型又調(diào)整其噪信比進(jìn)行了大量的仿真實驗，然后對實驗的結(jié)果圖像進(jìn)行了深入的分析、比較，總結(jié)出了具有一定理論和實用價值的結(jié)論。
  • We also analyze the influence of the boundary condition 、 safety distance and deceleration probability to the traffic flow . finally , we propose an crossroad modle . this model is made up of one main road and one branches ： traffic with lights placed on the crossing , vehicles " breaking while running and turning to other direction while jamming . we investigate the velocity and flow of the model when the initial density , the brake and turning probabilities , the green to signal ratio are changed . then the reasons causing all the kinds of phenomena are analyzed
    最后研究了周期性邊界條件下的十字路口的ca模型，該模型由一條主干道和一條支道組成，在干道與支道的交叉路口設(shè)置紅綠燈，車輛在運行中對突發(fā)事件發(fā)生反應(yīng)的剎車，路口的車輛可以轉(zhuǎn)向等各種實際交通行為，并通過計算機模擬，研究模型在改變車輛的初始密度、剎車概率、轉(zhuǎn)向概率、紅綠燈信號的綠信比等各種情況下支、主干道車輛的速度、流量的變化，并分析在各種情況下交通狀況的成因，提出改善交通的有效措施。
