Tidal fluctuations in a leaky confined aquifer: Dynamic effects of an overlying phreatic aquifer

Tidal fluctuations in a leaky confined coastal aquifer are damped significantly due to leakage into an overlying phreatic aquifer. Jiao and Tang [1999] presented an analytical solution to a simple model describing this phenomenon. Their solution assumes th ...

On the learning mechanism of adaptive filters

Ali H. Sayed

This paper highlights, both analytically and by simulations, some interesting phenomena regarding the behavior of ensemble-average learning curves of adaptive filters that may have gone unnoticed. Among other results, the paper shows that even ensemble-ave ...

Band-mixing and coupling in single and double quantum wire structures

Elyahou Kapon, Marc-André Dupertuis, Daniel Oberli

The electronic states in the conduction and valence bands of quantum wires are studied by means of the effective mass hamiltonian and the Luttinger hamiltonian. The band mixing effects due to the wire geometry are fully taken into account by an accurate fi ...

Robustness and convergence of adaptive schemes in blind equalization

Ali H. Sayed

We pursue a time-domain feedback analysis of adaptive schemes with nonlinear update relations. We consider commonly used algorithms in blind equalization and study their performance in a purely deterministic framework. The derivation employs insights from ...

Coherent Optical-Pumping of Semiconductor-Lasers

Michael Pfister, Marc-André Dupertuis

The influence of coherent optical pumping in semiconductor lasers is investigated theoretically. In particular the mathematical conditions under which an optically pumped system behaves like an electrically (incoherently) pumped system are derived. We show ...

Interpretation of mixing effects in a tubular recycle polymerization reactor packed with static mixers

Albert Renken, Thierry Meyer

Results presented in previous papers on partial segregation of a chain-transfer agent feedstream in a tubular recycle reactor packed with static mixers for the soln. polymn. of styrene are interpreted with the segregated feed model (SFM). Exptl. results ar ...
