With the exception of the harmonic oscillator, quantum wave packets usually spread as time
evolves. This is due to the non-linear character of the classical equations of motion which …

Sulfated zirconia with S content of 2 wt.% equivalent to complete coverage of its surface was
studied by infrared spectroscopy. At least four sulfated species were identified and exhibited …

The use of wavelets in the broad areas of source coding, communications, and networks is
surveyed. Specifically, the impact of wavelets and wavelet theory in image coding, video …

We show, both experimentally and theoretically, that sympathetic cooling of 87 Rb atoms in
the| F= 2, m F= 2> state by evaporatively cooled atoms in the| F= 1, m F=− 1> state can be …

Scalable video coding (SVC) differs form traditional single point approaches mainly because
it allows to encode in a unique bit stream several working points corresponding to different …

In this paper, we describe and optimize a general scheme based on lifting transforms on
graphs for video coding. A graph is constructed to represent the video signal. Each pixel …

This paper proposes an efficient approach for adaptive directional wavelet transform (WT)
based on directional prefiltering. Although the adaptive directional WT is able to transform …

We propose a complete video encoder based on directional" non-separable" transforms that
allow spatial and temporal correlation to be jointly exploited. These lifting-based wavelet …

We present a new graph-based transform for video signals using wavelet lifting. Graphs are
created to capture spatial and temporal correlations in video sequences. Our new transforms …

We present a new multiple-description coding (MDC) method for scalable video, designed
for transmission over error-prone networks. We employ a redundant motion-compensated …
