The radio frequency (RF) spectrum is a natural resource used by wireless network operators to provide radio communications and transmission systems. The scarcity of RF spectrum has led to the development of dynamic spectrum access techniques to achieve more efficient spectrum utilisation. A number of...

VHF-GD technique improves silane utilisation and leads, thus, to further cost reduction.Finally, by combining the VHF-GD technique and the "micromorph" concept "real" tandem cells (i.e. a superposition of two cells with distinctly different band gaps) can be deposited at low temperatures witho...
utilisation distributionwestern rattlesnakeContext. Despite the diversity of available home range estimators, no single method performs equally well in all circumstances. It is therefore important to understand how different estimators perform for data collected under diverse conditions. Kernel density ...

The monitoring tools to achieve such materials, such as in situ optical emission spectroscopy and a new parameter called "gas utilisation parameter" have been described. In this article we have reported results of the tandem "micromorph" cell with 11.4% stabilized efficiency using standard amorphous...
