چکیده
Let Γ be a planar crystallographic group and let g : R → R be an expanding affine mapping satisfying gΓg ⊂ Γ. Then choose a complete set of right coset representatives δ1, . . . , δn of Γ/gΓg . We call the attractor T of the iterated function system g(T ) = δ1(T ) ∪ . . . ∪ δn(T ) a crystallographic reptile if the collection

Topology of Crystallographic Tiles
We study self-affine tiles which tile the n-dimensional real vector space with respect to a crystallographic group. First we define classes of graphs that allow to determine the neighbors of a given tile algorithmically. In the case of plane tiles these graphs are used to derive a criterion for such tiles to be homeomorphic to a disk. As particular application, we will solve a problem of Gelbri...
متن کاملLocal stability criterion for self-gravitating disks in modified gravity
We study local stability of self-gravitating fluid and stellar disk in the context of modified gravity theories which predict a Yukawa-like term in the gravitational potential of a point mass. We investigate the effect of such a Yukawa-like term on the dynamics of self-gravitating disks. More specifically, we investigate the consequences of the presence of this term for the local stability of t...
متن کاملThe place of the Principle of Proceedings within a reasonable time in the criminal proceedings
Observing a reasonable deadline throughout the criminal investigation process, as one of the most fundamental defensive rights of the accused, emphasizes the importance of reasonable expediting in the process of proceedings in a high degree of accuracy, which considers necessary for the fair trial and the desired outcome of criminal proceedings. Delivering justice within a reasonable time is on...
متن کاملThree-Phase to Single-Phase Matrix Converters: New Topology Based on New Control Method
In this paper, a new topology is proposed for three-phase to single-phase matrix converters, where more voltage levels are produced in the output in comparison with the conventional topologies. In addition, a new control method based on minimum error between the generated and the desired output voltages is proposed for three-phase to single-phase matrix converters. In the proposed control metho...
متن کاملIsogeometric Topology Optimization by Using Optimality Criteria and Implicit Function
A new method for structural topology optimization is introduced which employs the Isogeometric Analysis (IA) method. In this approach, an implicit function is constructed over the whole domain by Non-Uniform Rational B-Spline (NURBS) basis functions which are also used for creating the geometry and the surface of solution of the elasticity problem. Inspiration of the level set method zero level...
