On the study of four-parallelogram filter banks [PDF]

open access: yes, 1996
The most commonly used 2-D filter banks are separable filter banks, which can be obtained by cascading two 1-D filter banks in the form of a tree. The supports of the analysis and synthesis filters in the separable systems are unions of four rectangles ...

Strong coupling of optical nanoantennas and atomic systems

open access: yes, 2013
An optical nanoantenna and adjacent atomic systems are strongly coupled when an excitation is repeatedly exchanged between these subsystems prior to its eventual dissipation into the environment. It remains challenging to reach the strong coupling regime

The Effect of Air Humidity on the Performance of DC Link Capacitor Components

open access: yesEnergies
DC link capacitors (DCLCs) are key devices in converters. The relative humidity affects the performance of the elements of a DCLC. Currently, there are relatively few studies on the effect of relative humidity on the electrical characteristics of the ...
