Non - preemptive priority queueing models with changeover times and switching threshold 帶有轉(zhuǎn)換時間和閾值的非搶占優(yōu)先權(quán)排隊模型
In the switched - on condition , and below the respective switching threshold set , the output relays are in the working condition and the relay contacts are closed 當(dāng)開關(guān)打開但未達(dá)到各個開關(guān)設(shè)定的閾值時,輸出繼電器處于工作狀態(tài),繼電觸點(diǎn)閉合。
To make use of the maximum signal margin with the maximum scanning distance tolerance , the switching threshold should be set at the mid - way point between the background and mark signals 在使用具有最大掃描距離偏差的最大信號邊限時,轉(zhuǎn)換門限應(yīng)該設(shè)置在背景與標(biāo)識信號的正中間?
Three connected comparators each with a comparison potentiometer enable the setting of three different switching thresholds , which correspond to a certain loading of the connected strain gauge force transducers 三個相連的比較電路每一個都有一個比較電壓計,可以根據(jù)所連接的應(yīng)變力傳感器的荷載設(shè)定三個不同的開關(guān)閾值。
Furthermore , analytical model for adaptive coded modulation is proposed , through which channel snr switching thresholds with the aim of throughput maximization of adaptive coded modulation are obtained with the method of lagrange , and then the average throughput performance of the adaptive system is obtained 通過建立自適應(yīng)編碼調(diào)制研究模型,本文還應(yīng)用拉格朗日函數(shù)法得到了使自適應(yīng)編碼調(diào)制系統(tǒng)吞吐量性能最大的信道信噪比轉(zhuǎn)換門限,進(jìn)而得到自適應(yīng)系統(tǒng)的平均吞吐量性能。
