The effort in reducing the area of AES implementations has largely been focused on Application-Specific Integrated Circuits (ASICs) in which a tower field construction leads to a small design of the A...
THE PARALLEL IMPLEMENTATION OF ALGORITHMS FOR FINDING THE REFLECTION SYMMETRY OF THE BINARY IMAGES
Reflection Symmetry of Images Binary Images High-Performance Computing Parallel Performance Evaluation
2017/6/19
In this paper, we investigate the exact method of searching an axis of binary image symmetry, based on brute-force search among all potential symmetry axes. As a measure of symmetry, we use the set-th...
We state the defining characteristic of mathematics as a type of symmetry where one can change the connotation of a mathematical statement in a certain way when the statement's truth value remains the...
Spontaneous Symmetry Breaking in Quantum Systems:Emergence or Reduction?
Emergence More is Different Symmetry Breaking Earman's Principle
2016/6/14
Beginning with Anderson (1972), spontaneous symmetry breaking (SSB) in infinite quantum systems is often put forward as an example of (asymptotic) emergence in physics, since in theory no finite syste...
Dynamics,Symmetry,and the Levels of Selection
levels of selection natural selection group selection evolutionary process dynamics symmetry symmetry transformation
2016/6/13
Most attempts to answer the question of whether populations of groups can undergo natural selection focus on properties of the groups themselves rather than the dynamics of the population. Those appro...
A Relic of a Bygone Age?Causation,Time Symmetry and the Directionality Argument
Causation direction of time time asymmetry time symmetry time reversal
2016/6/13
Bertrand Russell famously argued that causation is not part of the fundamental physical description of the world, describing the notion of cause as "a relic of a bygone age." This paper assesses one o...
Symmetry,empirical equivalence,and identity

2016/6/13
The paper proposes a novel approach to the much discussed question of which symmetries have direct empirical significance and which do not. The approach is based on a development of a recently propose...

The Discrete Logarithm Problem is at the base of the famous Diffie Hellman key agreement algorithm and many others. The key idea behind Diffie Helmann is the usage of the Discrete Logarithm function i...
For large ranks, there is no good algorithm that decides whether a given lattice has an orthonormal basis. But when the lattice is given with enough symmetry, we can construct a provably deterministic...
