How can this much video fit on a DVD and why can't I do it, too? A. Digital videodiscs can store different amounts of information, depending on the number of data layers available.
Depending on the end-to-end transmission capacity between a source and a destination, the number of data layers received determines the quality perceived by the destination.
By the support of adaptive modulation and coding in WiMAX, the radio resources can be optimally allocated when performing multicast so as to dynamically adjust the number of data layers received by users.
However, IDM offers a flexible configuration, which is desirable for joint communication and positioning, because the data rate can be easily adapted by changing the number of data layers M instead of changing the modulation scheme[23].
The calculated vulnerability index obtained by using all seven factors is considered as an unperturbed while the vulnerability computed using a lower number of data layers was considered as a perturbed one (Babiker et al. 2005).
The measure can be expressed as: S_{i} = left| {frac{v}{N} - frac{{v^{prime}}}{n}} right| (4 where S i is the sensibility, v and v′ are the unperturbed and the perturbed vulnerability indices, respectively; N and n are the number of data layers used to compute v and v′.
For example, population estimates (or maps derived from interpolating population location data) can be used together with vegetation type classes and any of a number of other spatial data layers in a geographic information system (GIS) to provide finer-grained units over which the field data can be applied (given that adequate field data exist to characterize each of the basic map units).
The present European Atlas of the Seas consists of background data layers designed to be displayed as map backdrop, as well as a number of thematic data layers, classified under 8 main categories: geography, nature, tourism, security and safety, people and employment, transport and energy, governance and European policies, fisheries and aquaculture.
As such, for each species, we built models based on all combinations of n−1 data layers, where n is the total number of layers.
In this study, first spatially explicit mapping of SOC and SIC at 250 m resolution and an estimate of their pool size in India was undertaken using a large number of remote sensing derived data layers and data mining approach.
