Clustering of galaxies at faint magnitudes
Significant uncertainties exist in the measured amplitude of the angular two-point correlation function of galaxies at magnitudes I 26 and fainter. Published results from HST and ground-based galaxy catalogs seem to differ by as much as a factor of 3, and it is not clear whether the correlation amplitude as a function of magnitude increases or decreases in the faintest magnitude bins. In order ...
متن کاملMagnetic declination stops migratory birds getting lost at sea
In the 1700s, scientists, sailors, engineers and explorers were trying to work out how to navigate east to west at sea. The stakes were high; many lives were lost because sailors could not reliably measure longitude. Eventually, the invention of accurate timepieces allowed sailors to use the time in their current location, and the time at a fixed reference, to calculate longitude. But how do lo...
متن کاملDeclination line and tones variati
Chinese is a tone language. As a tone language, each lexical item has an inherent tone pattern. In Chinese there are four tones : high, rising, low and falling. Our experiment investigates first the pattern of declination in Standard Chinese broadcasts and TV news speech, secondly the interaction of this effect with the sentence lenght and finally the evolution of the tones F0 values all throug...
متن کاملF0 declination in Russian revisited
This paper deals with F0 declination in Russian. The study was conducted using statistical data derived from the Corpus of Professionally Read Speech. The results confirm the relationship between F0 slope and the utterance length for Russian. At the same time they reveal a) individual strategies in preplanning declination slope of the phrase or utterance; b) strong dependency of the F0 slope on...
متن کاملAngular Declination and Perceived Distance
In two experiments involving a total of 83 participants, the effect of a vertical angular optical compression on the perceived distance and size of a target on the ground was investigated. Replicating an earlier report (Wallach & O’Leary, 1982), reducing the apparent angular declination below the horizon produced apparent object width increases (by 33%) consistent with the perception of a great...
