Additionally, characteristic (234 U/(238)U activity ratio and δ 34 S values may also be used to trace the mobility of the ore zone groundwater after mining has ended.
Hawelka et al. [12] meanwhile, looked at international population mobility, tracing the number of international tourists, again based on geolocated Twitter data; whilst Beiró et al. took a similar approach to domestic commuting patterns [13].
They found from the "mobility traces" - the evident paths of each mobile phone - that only four locations and times were enough to identify a particular user.
Furthermore, we show that, for some of the mobility traces, the network formed by periodic encounters forms a small-world structure.
Using synthetic and real-world mobility traces, the proposed predictor does not only outperform existing mobility prediction algorithms but achieves accuracy scores higher by an order of magnitude.
To this end, we use the mobility traces from mobile phones and the daily self-reported flu-like and cold symptoms of 29 individuals from February 20 , 2013 to March 21 , 2013
While in the developed world, much information of what can be inferred from mobile phone data is already known (population density, some of the mobility traces, …), this information can be very valuable in the developing world where census data is often unavailable or several years old.
An MMC is built out from the mobility traces observed during the training phase and is used to perform the attack during the testing phase.
The mobility traces for 451 nodes moving along the simulated roads, with a mean speed of 60 km/h, are generated by SUMO [9].
We would like to underline a major difference between this work and that by de Montjoye et al., as in theirs the training set also includes the points used for the testing and the mobility traces are extracted from mobile operators' call data records, instead of exact GPS points.
