Satellite remote sensing offers a convenient way to monitor changes in the thermal budgets of Earth’s subaerially active volcanoes. By using data acquired by the National Aeronautics and Space Administration’s Moderate Resolution Imaging Spectro-radiometer, we have calculated the amount of heat released into the atmosphere by 45 volcanoes active during 2001 and 2002, in order to quantify the co...

0556-2821=20 If the halo dark matter were composed of primordial black holes (PBHs) with mass between 1016 and 1020 g, their gravitational interaction with test masses of laser interferometer may lead to a detectable pulselike signal during the fly-by. If a proof-mass noise of 3 10 15 m=s2=Hz1=2 down to 10 5 Hz is achieved by the Laser Interferometer Space Antenna, the event rate, with signal-t...

Piezoelectric Energy Harvesting Systems play a vital role in energizing microelectronic devices with the low-frequency operation. Here, novel piezoelectric energy harvesting device has been developed for low power electronic devices. The consists of cantilever poles projecting outwards and cantilevers one end is connected to wind-catcher, another torsional spring. signifies its application plac...

This paper analyses two narrowband speech codecs, the 4.8 kbit/s FS1016 coder and the 8 kbit/s G729 coder, using objective psychoacoustic measures. Four measures are used: loudness, sharpness, roughness and tonality. The results show sharpness and roughness as the two major contributing factors to the subjective difference between the two coders.

BACKGROUND Associations between an increase in coronary heart disease occurrence and low atmospheric temperatures have been reported from mortality data and hospital admission registries. However, concomitant increases in noncardiovascular case fatality rates and selection bias of hospital cases may weaken this observation. In this study, we addressed the question of the relationships between f...
