Sifting attacks in finite-size quantum key distribution [PDF]

open access: yesNew J. Phys. 18 053001 (2016), 2015
A central assumption in quantum key distribution (QKD) is that Eve has no knowledge about which rounds will be used for parameter estimation or key distillation. Here we show that this assumption is violated for iterative sifting, a sifting procedure that has been employed in some (but not all) of the recently suggested QKD protocols in order to ...

Packing and Padding: Coupled Multi-index for Accurate Image Retrieval [PDF]

open access: yes, 2014
In Bag-of-Words (BoW) based image retrieval, the SIFT visual word has a low discriminative power, so false positive matches occur prevalently. Apart from the information loss during quantization, another cause is that the SIFT feature only describes the ...

Is God really good to the upright? Theological educators exploring Psalm 73 through the Jungian lenses of sensing, intuition, feeling and thinking

open access: yesHTS Teologiese Studies/Theological Studies, 2020
Psalm 73 is a challenging Psalm in which the Psalmist draws on rich imagery to juxtapose doctrine and experience and to juxtapose the goodness of God with divine retribution.

Quick sift(QSIFT), an approach to reduce SIFT computational cost [PDF]

open access: yes2017 Artificial Intelligence and Signal Processing Conference (AISP), 2017
SIFT has been proven to be the most robust local rotation and illumination invariant feature descriptor. Being fully scale invariant is the most important advantage of this descriptor. The major drawback of SIFT is time complexity which prevents utilizing SIFT in real-time applications.

SIFT -- File Fragment Classification Without Metadata [PDF]

open access: yesarXiv, 2023
A vital issue of file carving in digital forensics is type classification of file fragments when the filesystem metadata is missing. Over the past decades, there have been several efforts for developing methods to classify file fragments. In this research, a novel sifting approach, named SIFT (Sifting File Types), is proposed.

Interpreting and responding to the Johannine feeding narrative : an empirical study in the SIFT hermeneutical method amongst Anglican ministry training candidates [PDF]

open access: yes, 2012
Drawing on Jungian psychological type theory, the SIFT method of biblical hermeneutics and liturgical preaching maintains that different psychological type preferences are associated with distinctive readings of scripture.
