The Bootstrapping Service [PDF]

open access: yes26th IEEE International Conference on Distributed Computing Systems Workshops (ICDCSW'06), 2006
We outline a lightweight architecture to support novel application scenarios for P2P systems. These scenarios include merging and splitting of large networks, or multiplexing relatively short-lived applications over a pool of shared resources. In such scenarios, the architecture needs to be quickly and efficiently (re)generated frequently, often from ...

Quantitative Analysis of Colostrum Bacteriology on British Dairy Farms

open access: yesFrontiers in Veterinary Science, 2020
Total bacterial counts (TBC) and coliform counts (CC) were estimated for 328 colostrum samples from 56 British dairy farms. Samples collected directly from cows' teats had lower mean TBC (32,079) and CC (21) than those collected from both colostrum ...

The Stationary Bootstrap [PDF]

open access: yesJournal of the American Statistical Association, 1994
Abstract This article introduces a resampling procedure called the stationary bootstrap as a means of calculating standard errors of estimators and constructing confidence regions for parameters based on weakly dependent stationary observations. Previously, a technique based on resampling blocks of consecutive observations was introduced to construct ...
