We present a four-part conceptual model based on the recreation opportunity spectrum framework, and tested it by using survey data and automatic counters in urban forests of Oslomarka in Norway.
The heritage and recreation opportunity spectrum indicators, adapted from Maes et al. ([2011]), are mapped through a gradient that shows the density of elements by km2, and their proximity to the city center.
Swinging to the other end of the opportunity spectrum, the company could just give away all these experiences to artists, boosting their loyalty to Spotify and getting them to promote their presence there instead of on competing streaming services like Apple Music.
To detect spectral opportunities, various spectrum sensing algorithms are presented, where energy detection-based spectrum sensing is an effective and simple detection technique [1 3].
Cognitive capability refers to the ability to sense opportunities in spectrum where and when channels are not utilized by PUs.
The system performance is analyzed for the large-scale overlay CR network [19], where the secondary users can help the primary data transmission to exchange for the opportunity of spectrum sharing.
Just as focusing optics can be replaced by nanoscale resonances to provide optical concentration (as described above), nanostructures also provide an opportunity for spectrum splitting without external macroscopic optics.
We devise an LTE system to be aware of these spectrum opportunities and to exploit them as long as the opportunity remains, i.e., ceasing transmission once the licensed system starts its activity.
