Fully rotationally resolved spectra of the two lowest-frequency bands ~the origin (00 0 ) and the inversion (140 1) band! of the S1(n p*)ÃS0 transition of jet-cooled (Trot'6 K) acetaldehyde, CH3CHO, have been recorded with a resolution of '0.01 cm21 using ...
The development of narrow bandwidth tunable laser systems in the vacuum UV region of the electromagnetic spectrum and of new exptl. methods has recently enabled a significant improvement in the resoln. that can be achieved by photoelectron spectroscopy. Th ...
The continuous time random walk approach for hopping conduction in disordered systems is modified to obtain accurate DC conductivity values over a wide range of hopping site densities. The modification involves eliminating a small fraction of particularly ...
An analysis of the phase spectrum of the DA pulsating white dwarf G29–38 over many seasons has been performed. This complements a companion paper which analyses the evolution of the temporal spectrum of G29–38.We show that, with one exception, the rela ...
Motivated by the human ability to maintain a high level of speech recognition when large parts of the spectrogram are masked (i.e. dominated) by noise, the original "missing data" (MD) approach to noise robust speech recognition was based on the paradigm w ...
A theor. model is presented to account for the Fano-like interference lineshapes on multiphonon continua in the electronic spectrum of NO in rare-gas solids. The model is based on the coupling of the optical transitions to 1 single local mode, while the la ...
We investigate the capacity and mutual information of a broadband fading channel consisting of a finite number of time-varying paths. We show that the capacity of the channel in the wideband limit is the same as that of a wideband Gaussian channel with the ...
The widespread use of sensitive electronic devices has increased the interest on transients, in particular those caused by lightning (direct and/or indirect). This tutorial presents the latest developments in modelling the electromagnetic (indirect) effect ...
We present femtosecond gain measurements in microcavity-embedded quantum wells. When the excitonic transition is saturated by an intense pump field, the spectrum measured with a weak probe pulse is strongly modulated by pump-probe wave mixing processes. A ...
In mobile ad-hoc networks nodes need to cooperate to communicate, but there are many reasons for non-cooperation. Saving power or preventing other nodes from obstructing a service are merely selfish reasons for non-cooperation, whereas nodes may also activ ...
