EURASIP Journal on Advances in Signal Processing, 2006 Carrier frequency offset (CFO) is a serious drawback in orthogonal frequency division multiplexing (OFDM) systems. It must be estimated and compensated before demodulation to guarantee the system performance. In this paper, we examine the performance of

The Embryonic Development of the Cotylean Polyclad Phrikoceros jannetae
Acta Zoologica, EarlyView.ABSTRACT Polyclads exhibit distinct developmental modes ranging from direct to indirect development, with several transitional stages also recognised. The existence of an indirect developmental mode in polyclads with a planktonic life history stage in the form of a free‐swimming larva is unique among all free‐living flatworms and makes polyclads a ...

Dianci bileiqi, 1999 针对串补系统的稳态计算，提出了一种基于ＭＯＶ两端电压谐波分析的ＭＯＶ线性模型，该模型比以前基于经验公式的ＭＯＶ线性模型具有更强的针对性和更广的适用范围。该模型应用于串补系统的短路计算，可确定短路期间ＭＯＶ的线性阻抗，不仅可以得出短路电流，而且可以计算ＭＯＶ两端的电压波形和每个周波流过ＭＯＶ的能量，与ＥＭＴＰ计算结果的比较表明该模型具有较高的准确性。

Journal of Sociolinguistics, EarlyView.ABSTRACT This study examines how Taiwanese members of parliament (MPs) deploy self‐referring expressions—specifically, the formal first‐person singular běnxí—to negotiate their institutional standing and project political power. By operationalizing access to objective power using the margin of victory (MoV) as one possible proxy, the research shows ...

Dianci bileiqi, 2017 金属氧化物限压器（MOV）作为输电线路串联补偿装置的重要组成部分,限制系统故障时电容器极间的暂态过电压。MOV通常由多个单元并联构成,故障瞬间会通过大电流、吸收高能量。MOV单元间暂态负荷应力的分布状况直接影响MOV的保护特性,应通过优化设计确保其暂态运行可靠性。以某500 kV交流超高压带串补装置的系统为例建立了数值仿真模型,利用EMTP-ATP研究了串联补偿装置在不同运行方式下区外故障和区内故障时MOV的负荷应力。综合MOV的电压-温度特性试验结果 ...
