Some research on attentional control in working memory has emphasized theoretical capacity differences. However, strategic behavior, which has been relatively unexplored, can also influence attentional control and its relationship to cognitive performance. In two experiments, we examined the relationship between attentional control (measured with operation span) and interference in a part-list ...

during a period of 7 years (1997-2003) we were received pairs of serum and csf of 27 suspicious clinically cases from neurology department of several hospitals in tehran. among them 7 were serologically positive for progressive rubella panencephalitis (prpe) and 2 were positive for sub acute sclerosing panencephalitis (sspe). rubella virus was isolated from 4 of 7 serologically positive cases o...

Artificial neural network (ANN) has application in communication engineering in diverse areas such as channel equalization, channel modeling, error control code because of its capability of nonlinear processing, adaptability, and parallel processing. On the other hand, wavelet transform (WT) with both the time and the frequency resolution provides the exact representation of signal in both doma...

In order to determine the responses of morphological characteristics, yield and yield components of rapeseed (Brassica napus L.) to plant density and weed interference duration, a factorial experiment was conducted using a randomized complete block design with 3 replications at the Rice Research Institute of Iran (RRII) in Rasht, in the 2008 growing season. The factors comprised plant density a...
