nowadays, increasing of greenhouse gases emissionscussed by human activities is the main factor of climate change. global warming has also changed the frequency of extreme rainfall events in many areas. this research presents an analysis of how the change in the frequency of maximum daily rainfall under three emission scenarios in 2021-2040 periods in the khorasan-razavi province. the maximum d...

If the spatial-frequency of sinusoidal signals in a contrast-detection experiment varies randomly from trial to trial, then performance is decreased compared with that in a situation where it remains constant. This spatial-frequency uncertainty effect can more or less be compensated by presenting informative cues shortly before each trial. Single-band, as well as multiple-band models, have been...

Over the last years, there have been initiated several pilots with autonomous minibusses. Unlike regular bus services, minibusses serve a limited number of stops and more flexible schedules since they do not require drivers. This allows operation line through combination sublines, where subline serves subset consecutive in same order as original line. paper studies frequency setting (SFS) probl...
