In mathematics, the symmetric difference of two sets is the set of elements which are in one of the sets, but not in both. This operation is the set-theoretic kin of the exclusive disjunction (XOR operation) in Boolean logic. The logical operation exclusive disjunction, also called exclusive...
The paper offers a theoretical model of the difference operator and the symmetric difference operator for fuzzy sets. The general fuzzy set theory admits infinitely many definitions of these operators which have only to respect extreme values in very few marginal points. The approach suggested in the...
A collection of sets is symmetric-difference-free , respectively symmetric difference-closed , if the symmetric difference of any two sets in the collection lies outside, respectively inside, the collection. Recently Buck and Godbole (Size-maximal symmetric difference-free families of subsets of [ ...

Thesymmetric differenceof the sets is one of the basic operation of the sets, and it plaies an important role in measure theory and its applications. 集合的对称差是集合的基本运算之一,它在测度论及其应用中扮演着一个重要的角色。 更多例句>> ...
This article concludes by discussing the most important results obtained throughout the work in Section 7. 2. Model Description and Basic Tools 2.1. Basic Tools The present paper aims to describe our symmetric fractional map based on the 𝛿δ-th Caputo-like difference operator 𝑐Δ𝛿𝜂 c...
The most well-known mechanism for fermions to acquire a mass is the Nambu–Goldstone–Anderson–Higgs mechanism, i.e., after a spontaneous symmetry breaking, a bosonic field that couples to the fermion mass term condenses, which grants a mass gap for the

in a stream, it is called astream cipher. These types of ciphers are discussed in the next two sections. The main difference is that stream ciphers have performance and energy consumption advantages over block ciphers, and are easier to implement in hardware, however, stream ciphers are much ...
In this case, authentication and integrity are often obtained by digital signatures. However, as there is a huge performance difference between symmetric-key and public key cryptography, it is still interesting to look at symmetric-key-based solutions, due to the limited energy, communication ...
