A fast-convergence algorithm for reliability analysis based on the AK-MCS
Reliability Engineering & System Safety, 2021 Abstract In the field of reliability engineering, assessing the probability of failure of an event is usually a computationally demanding task. One way of tackling this issue is by metamodelling, in which the original computational-expensive model is approximated by a simpler metamodel.

Improved agreement of AIRS tropospheric carbon monoxide products with other EOS sensors using optimal estimation retrievals [PDF]
Atmospheric Chemistry and Physics, 2010 We present in this paper an alternative retrieval algorithm for the Atmospheric Infrared Sounder (AIRS) tropospheric Carbon Monoxide (CO) products using the Optimal Estimation (OE) technique, which is different from the AIRS operational algorithm.

Zig-zag sort: a simple deterministic data-oblivious sorting algorithm running in O(n log n) time [PDF]
Symposium on the Theory of Computing, 2014 We describe Zig-zag Sort---a deterministic data-oblivious sorting algorithm running in O(n log n) time that is arguably simpler than previously known algorithms with similar properties, which are based on the AKS sorting network.

Sieve algorithms for the shortest vector problem are practical
Journal of Mathematical Cryptology, 2008 The most famous lattice problem is the Shortest Vector Problem (SVP), which has many applications in cryptology. The best approximation algorithms known for SVP in high dimension rely on a subroutine for exact SVP in low dimension.

Primality Proving via One Round in ECPP and One Iteration in AKS [PDF]
Journal of Cryptology, 2003 In August 2002, Agrawal, Kayal and Saxena announced the first deterministic and polynomial-time primality-testing algorithm. For an input n, the Agarwal-Kayal-Saxena (AKS) algorithm runs in time $\tilde{O}(\log^{7.5} n)$ (heuristic time $\tilde{O}(\log^6

Adaptive Dual AK-D Tree Search Algorithm for ICP Registration Applications [PDF]
2006 IEEE International Conference on Multimedia and Expo, 2006 An algorithm for finding coupling points plays an important role in the iterative closest point algorithm (ICP) which is widely used in registration applications in medical and 3-D architecture areas. In recent researches of finding coupling points, Approximate K-D tree search algorithm (AK-D tree) is an efficient nearest neighbor search algorithm with
