Preprint submitted to Elsevier 4 September 2008 We have observed cosmic-ray electrons from 10 GeV to 800 GeV by a long duration balloon flight using Polar Patrol Balloon (PPB) in Antarctica. The observation was carried out for 13 days at an average altitude of 35 km in January 2004. The detector is an imaging calorimeter composed of scintillating-fiber(More)
Simultaneous measurements of high-frequency pump-enhanced airglow and ionospheric temperatures at auroral latitudes Abstract: Simultaneous measurements of enhanced airglow at 6300Å and plasma temperatures from transmitting a powerful high frequency electromagnetic pump wave from the EISCAT-Heating facility into the ionospheric F region at auroral latitudes(More)
ARSTRACT This paper proposes a matching algorithm for two In the process of visually matching two mutually-distorted waveforms, each having partial mutuallyaistorted waveforms, we first try to detect major differences in the hierarchical structure of its scale-space. corresponding points between them by observing their 'I'his algorithm is applied to(More)
