INTERFEROMETRIC PHASE CALIBRATION SOURCES IN THE DECLINATION RANGE 0 ◦ TO − 30 ◦ Joshua
We present a catalog of 321 compact radio sources in the declination range 0 > δ > −30. The positions of these sources have been measured with a two–dimensional rms accuracy of 35 milliarcseconds using the NRAOa Very Large Array. Each source has a peak flux density> 50 mJy at 8.4 GHz. We intend for this catalog to be used mainly for selection of phase calibration sources for radio interferomete...
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 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 کاملThe perception of fundamental frequency declination.
A series of experiments was carried out to investigate how fundamental frequency declination is perceived by speakers of English. Using linear predictor coded speech, nonsense sentences were constructed in which fundamental frequency on the last stressed syllable had been systematically varied. Listeners were asked to judge which stressed syllable was higher in pitch. Their judgments were found...
متن کاملPulsar Astrometry with the VLBA
Many features of the Very Long Baseline Array (VLBA) contrive to make it the best telescope for pulsar astrometry. The measured proper motions and parallaxes allow distances and transverse velocities to be determined. These in turn provide clues to questions spanning nuclear astrophysics on scales of 10−23 m to the distribution of gas in the Galaxy on scales of 10 m. Three pulsars are discussed...
