Opening the attentional window in attentional blink: An attentional cuing study

To investigate whether the functioning of cognitive control is contingent upon the attentional set in attentional blink (AB), which is a deficit in reporting the second (T2) of two targets when it occurs 200—500 ms after the first (T1) in a rapid serial visual presentation (RSVP) stream, this study examined the pattern of cuing effects in which two kinds of colored cues match (i.e., in the same attentional set) or mismatch (i.e., in a different attentional set) the color of the upcoming T2. Participants of the study were asked to monitor T1 and T2 in triple RSVP streams while the cue-T2 onset synchrony (CTOA) varied from 90 ms to 270 ms and the cue and T2 might or might not occur in the same RSVP stream as T1. Relative to the uncued condition, both the same-color and the different-color cues produced cuing effects, but the effect was larger and lasted for a longer time for the former than for the latter, whether the cue (and T2) and T1 occurred in the same stream or not. Cues with short CTOA in general enhanced T2 performance more greatly during the AB period than outside of the AB period, suggesting that cues with short CTOA could open the attentional window in advance of T2 and thus facilitate the T2 processing. These findings are consistent with the theory that the salient stimulus captures attention and opens the attentional window irrespective of the attentional set defined for the target; but the attention capture effect of the cue can be quickly overridden by the top-down control when the cue does not match the attention set. Thus both the top-down attentional control setting and the bottom-up attentional capture process function during attentional blink.

Linked-Tree： An Aggregate Query Algorithm Based on Sliding Window over Data Stream

How to process aggregate queries over data streams efficiently and effectively have been becoming hot re search topics in both academic community and industrial community. Aiming at the issues, a novel Linked-tree algorithm based on sliding window is proposed in this paper. Due to the proposal of concept area, the Linked-tree algorithm reuses many primary results in last window and then avoids lots of unnecessary repeated comparison operations between two successive windows. As a result, execution efficiency of MAX query is improved dramatically. In addition, since the size of memory is relevant to the number of areas but irrelevant to the size of sliding window, memory is economized greatly. The extensive experimental results show that the performance of Linked-tree algorithm has significant improvement gains over the traditional SC （Simple Compared） algorithm and Ranked-tree algorithm.     

Kaiser窗三谱线插值电力谐波分析

在非同步采样以及非整数周期截断情况下,快速傅里叶变换会产生频谱泄露和栅栏效应,使计算结果存在较大误差,无法得到准确参数。常用窗函数固定的旁瓣性能制约了已有加窗插值算法的误差修正效果。而凯赛(Kaiser)窗的主旁瓣高度之间的比重可依据需要自由选择,其主旁瓣能量的比例也近乎最大。文中提出基于Kaiser窗的三谱线插值FFT的电力谐波分析方法,推导了基波以及各次谐波的幅值、频率和初相位的插值修正公式。仿真结果表明,所提算法设计灵活且易于实现,在基波频率波动以及白噪声干扰下都有较高的谐波参数估计准确度,验证算法能够有效消除泄露和栅栏效应的影响,提高了谐波分析的准确性。
