With the advent of quantum key distribution (QKD) systems, perfect (i.e., information-theoretic) security can now be achieved for distribution of a cryptographic key. QKD systems and similar protocols use classical error-correcting codes for both error correction (for the honest parties to correct errors) and privacy amplification (to make an eavesdropper(More)

In this paper we consider the theoretical and practical management resources needed to reliably localize congested nodes/links and propose a solution based on decoding linear error control codes. We define the scalability of measurement-based network monitoring and relate this to the problem decoding of linear error control codes on a binary symmetric(More)
In this paper we investigate the fault diagnosis problem in IP networks. We provide a lower bound on the average number of probes per edge using variational inference technique proposed in the context of graphical models under noisy probe measurements. To obtain the bounds, we construct a graphical model using Bayesian networks. The advantages of the(More)
Descriptions of breastfeeding practices among residents in slum areas of Kolkata and the influence of breastfeeding on postpartum amenorrhoea is the focus of this study. Three out of four women initiate breastfeeding after one hour of birth and three out of five women squeeze the first milk from the breast before breastfeeding. Though the median duration of(More)
To my parents and my brother iii ACKNOWLEDGEMENTS I thank my advisor, Professor Steven W. McLaughlin for his guidance and constant encouragement that got me through every step in my PhD. He was very understanding and always rescued me whenever I got myself into trouble. It has been a pleasure and a privilege to work with him for the past five years. I would(More)
