The characteristic declination is the for day on which daily extraterrestrial irradiation a horizontal surface identical to its monthly average value. It was introduced as means determine values of irradiation. Herein, potential usefulness reduce computing time when mapping solar in complex urban areas explored. This simplification reduces demand by factor 30× while introducing +5% +8% error an...

[1] The daily variation of the geomagnetic field during quiet time at equinox features a longitudinal dependence, which is observed in the dip-latitude/longitude frame. Two explanations are considered: (1) the longitudinal changes of the geomagnetic latitude at constant dip-latitude and (2) the longitudinal variations of the main field, which modulates the ionospheric dynamo e.m.f. and determin...

We present radio observations for 29 southern Seyfert galaxies selected from a volume limited sample with cz < 3600 km s −1 , and declination δ < 0 •. Objects with declination −30 • < δ < 0 • were observed with the Very Large Array (VLA) at 6 cm (4.9 GHz) and objects with δ < −30 • were observed with the Australia Telescope Compact Array (ATCA) at 3.5 cm (8.6 GHz). Both the VLA and the ATCA obs...

In this study – which is part of an extensive investigation of the prosodic features of emotional speech – global trends of fundamental frequency were examined. The primary goal was to test the use of this parameter to characterize a specific set of emotions (happiness, anger, anxiety, sadness, disgust and boredom). Global F0 trend was measured in the form of the gradient of the linear regressi...

Two experiments are reported in which a pitch-level difference (PLD) model for prominence perception [Hermes and Rump, J. Acoust. Soc. Am. 96, 83-92 (1994)] is subjected to further tests. The model holds that the contribution of pitch to the perceived degree of prominence is proportional to the difference in pitch level between the vocalic nuclei of the accented and the previous syllable. In ex...

A comparative study is carried out between a semi-empirical low-latitude ionospheric model (SLIM). including calculated 01 630 nm airglow emission intensities predicted by the SLIM model, with ionospheric and r>I 630 nm airglow measurements carried out at Cachoeira Paulista (22.7”S, 45.O”W; geomag. 11.9”S), Brazil. A long series of regular measurements of ionospheric F-region peak electron dens...

This paper investigates various aspects of intonation and phonation in young adults with Down syndrome. The speech of nine speakers with Down syndrome was analyzed acoustically for different aspects of intonation and phonation. The results of these analyses were compared to similar speech samples of nine typical speakers of Standard British English. The controls were matched for age and gender....
