in response to the demand for soil spatial information, the acquisition of digital auxiliary data and their matching with field soil observations is on the increase. with the harmonization of these data sets, through computer based methods, the so-called digital soil maps are increasingly being found to be as reliable as the traditional soil mapping practices, and with no prohibitive costs. the...

4.1 INTRODUCTION In sampling theory the auxiliary information is being utilized in following ways:  Utilization of information at pre-selection stage i.e. for stratifying the population.  Utilization of information at selection stage i.e. in selecting the units with probabilities proportional to some suitable measure of size (size being based on some auxiliary variables).  Utilization of inf...

I analyze the reidentifiability of the Heritage Health Prize dataset taking into account the auxiliary information available online and offline to a present-day adversary. A key technique is identifying providers, which is useful both as an end in itself and as a stepping stone towards identifying members. My primary findings are: 1. Grouping providers based on shared members results in the for...

-In this paper, we propose a novel method for improving digital image recovery from print – scan channel. A printed photograph is not sufficient to recover the original digital image because of distortions introduced in scanning process. The proposed approach recovers the print – scan images with improved quality. We solve this approximation problem by combining both the photograph and the digi...
