Lossless and Unlimited Multi-image Sharing Based on Chinese Remainder Theorem and Lagrange Interpolation

open access: yes, 2014
[[abstract]]This study proposes a novel multi-image threshold sharing scheme based on Chinese remainder theorem and Lagrange interpolation. The exceptional property of the scheme is its ability to retrieve any secret image without recovering all the ...

Symmetries of directed graphs and the Chinese remainder theorem

open access: yesJournal of Combinatorial Theory, Series B, 1980
AbstractIt is shown that a permutation group on a finite set is the automorphism group of some directed graph if and only if a generalized Chinese remainder theorem holds for the family of stabilizers. This result can be applied to examine some special permutation groups, including the general linear groups of finite vector spaces.

Three‐Dimensional Analytical Model of a Podium Structure With Rocking Columns of Square Cross Section

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Allowing structural systems to uplift and rock during seismic excitation has emerged as an effective and inherently self‑centering form of seismic isolation. This paper develops a computationally efficient 3D analytical model suitable for the understanding of the behavior of rocking bridges.

The complexity of the Chinese Remainder Theorem

open access: yes, 2023
The Chinese Remainder Theorem for the integers says that every system of congruence equations is solvable as long as the system satisfies an obvious necessary condition. This statement can be generalized in a natural way to arbitrary algebraic structures

Direction‐Aware Period Prediction for Seismic Risk Assessment and Application to an Urban Tall Building Portfolio in China

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Reliable estimation of the principal periods is essential for regional seismic risk assessment (RSRA) of urban building portfolios. For tall buildings, however, existing period‐prediction formulas are constrained by the lack of representative data, while building translational azimuths are neglected despite their importance for regional ...

Phase Unwrapping and A Robust Chinese Remainder Theorem

open access: yes, 2008
—In the conventional Chinese remainder theorem (CRT), a small error in a remainder may cause a large error in the solution of an integer, i.e., CRT is not robust.

New results on multidimensional Chinese remainder theorem [PDF]

open access: yes, 1994
The Chinese remainder theorem (CRT) [McClellan and Rader 1979] has been well known for applications in fast DFT computations and computer arithmetic.

Valuing Stock Liquidity: Theory and Evidence From the Collapse of Lehman Brothers

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT This study examines the cross‐sectional relationship between stock return and stock liquidity (both level and risk) for the period when there was a huge decline in market‐wide funding liquidity from the collapse of Lehman Brothers. We propose a global game model to analyse the decisions of short‐term traders around the time Lehman Brothers ...

Density Conditions for k $k$ Vertex‐Disjoint Triangles in Tripartite Graphs

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT Let n , k $n,k$ be positive integers such that n ≥ k $n\ge k$ and G $G$ be a tripartite graph with parts A , B , C $A,B,C$ such that ∣ A ∣ = ∣ B ∣ = ∣ C ∣ = n $| A| =| B| =| C| =n$. Denote the edge densities of G [ A , B ] , G [ A , C ] $G[A,B],G[A,C]$ and G [ B , C ] $G[B,C]$ by α , β $\alpha ,\beta $ and γ $\gamma $, respectively.
