In the RRM server, as described in the previous section, every geolocation has its own spectrum map, and the spectrum map stays either in the learning stage or in the serving stage.
If the RRM server has only a few WSAPs that inform the server about a change in the channel occupancy in a densely populated area, the RRM server cannot build a reliable radio resource map or the spectrum map that reflects the latest occupancy status of white space channels.
First, we show that the spectrum of the twisted Szegedy walk on the quotient graph can be expressed by mapping the spectrum of a twisted random walk onto the unit circle.
In contrast to 300 ms (=10 ms × 30 channels) of the conventional approach, with the extended spectrum map, the expected spectrum sensing time,, is below 300 ms.
In order to maintain the navigation abilities of the robot, the spatial modeling method of a human is imitated to describe the relations of function area as a global topological map by the spectrum clustering algorithm.
Regardless of success or failure in spectrum access, the WSAPs execute Algorithm 3 that updates the retrieved spectrum map with the spectrum sensing results.
The 'body map' described the spectrum of transcripts from each organ of the human body collected from organ-specific mRNA samples.
Given a sequence of isotopic distributions, such that no more than k−1 distributions can intervene between any matching pair, the algorithm runs in time O k! n) and returns an optimal (maximum scoring) map of the spectrum into matched pairs of distributions.
To account for the differential stimulation of the four avian cone types, we mapped the spectra onto Goldsmith's [40] tetrahedral colour space that has recently been recommended for analyses of colour patterns as processed by tetrachromatic visual systems [41].
Abbot helped Langley map the infrared spectrum of the Sun and measure the total solar radiation energy received by the Earth over a given area and time a value called the solar constant.
