Only by recognizing the importance of an energy portfolio rich in fuel source diversity will we preserve America's access to stable and affordable power.
"The expected benefits of these projects are huge, including cheap electricity, new job and business opportunities, 'greener' energy and wider energy source diversity," Maria Patrikainen, an analyst based in London for IHS Global, said by e-mail.
Research from the University of California (Source: Diversity Management in Corporate America 2007) which looked over 829 companies over 31 years has confirmed that the most widely-implemented programmes change nothing: diversity training, performance evaluations and networking groups are widely used but have "no positive effects in the average workplace".
Exploiting both the source diversity and the variations in channel conditions can increase the system throughput.
However, little-to-no theory exists for the case of limited source diversity and a strongly scattering environment.
It mentions two basic possibilities: cooperative source diversity (repetition coding) and cooperative transmit diversity established through distributed space-time block coding (STBC) and a combination of both.
By contrast, communities that tend to be similar (even when not physically identical) and stable are observed where the source diversity is low.
We found moderate levels of maternal seed source diversity in primary seed rain across five leks in northwest Ecuador (unweighted mean alpha diversity α = 9.52, weighted mean αr = 3.52), with considerable variation among leks (αr range: 1.81 24.55).
As explained in detail above, given sufficient source diversity and a weakly scattering environment, the peak of the cross-correlation of signals recorded by two sensors in the environment corresponds to the travel time between them.
This methodology offers several advantages over currently used PTM detection methods including ease of use, rapidity, scale, and sample source diversity.
