Examples of Substitution Systems and Their Factors
نویسندگان
چکیده
The theory of substitution sequences and their higher-dimensional analogues is intimately connected with symbolic dynamics. By systematically studying the factors (in the sense of dynamical systems theory) of a substitution dynamical system, one can reach a better understanding of spectral and topological properties. We illustrate this point of view by means of some characteristic examples, including a rather universal substitution in one dimension as well as the squiral and the table tilings of the plane. Dedicated to Jean-Paul Allouche on the occasion of his 60th birthday

Application of queuing theory in inventory systems with substitution flexibility
Considering the competition in today’s business environment, tactical planning of a supply chain becomes more complex than before. In many multi-product inventory systems, substitution flexibility can improve profits. This paper aims to prepare a comprehensive substitution inventory model, where an inventory system with two substitute products with ignorable lead time has been considered, and e...
متن کاملResource allocation based on DEA for distance improvement to MPSS points considering environmental factors
This paper proposes a new resource allocation model which is based on data envelopment analysis (DEA) and concerns systems with several homogeneous units operating under supervision of a central unit. The previous studies in DEA literature deal with reallocating/allocating organizational resource to improve performance or maximize the total amount of outputs produced by individual units. In tho...
متن کاملQuotient G-systems and Green\'s Relations
In this paper, we first introduce the concepts of G-systems, quotient G-systems and isomorphism theorems on G-systems of n-ary semihypergroups . Also we consider the Green's equivalences on G-systems and further in-vestigate some of their properties. A number of n-ary semihypergroups are constructed and presented as examples in this paper.

Controlling the release of drugs and other therapeutic molecules has great importance in novel drug delivery. Nanoparticulate systems have the ability to control drug release and increase the presence of these compounds in blood flow and could convey them to a specific position. Growth factors are endogenous peptide which begins cellular signals to regulate cellular activities. The main problem...
