Ideal and Predictable Hit Ratio for Matrix Transposition in Data Caches

open access: yesMathematics, 2020
Matrix transposition is a fundamental operation, but it may present a very low and hardly predictable data cache hit ratio for large matrices. Safe (worst-case) hit ratio predictability is required in real-time systems.

Mixed Tiling Systems [PDF]

open access: yes, 2019
This thesis extends the theory of tiling iterated function systems developed in [BV18] and connects the theory to other areas of the tiling literature.

Test generation from recursive tile systems [PDF]

open access: yesSoftware Testing, Verification and Reliability, 2012
SUMMARYThis paper explores the generation of conformance test cases for recursive tile systems (RTSs) in the framework of the classical ioco testing theory. The RTS model allows the description of reactive systems with recursion and is very similar to other models like pushdown automata, hyperedge replacement grammars or recursive state machines.

Set Covering Problem in Transport Nets Expanding Models [PDF]

open access: yesTransactions of the VŠB-Technical University of Ostrava, Mechanical Series, 2012
The article deals with the problem of optimal coverage of utility centres in transport network. We can often encounter similar types of tasks in a real life.

A single strand: A simplified approach to DNA origami

open access: yesFrontiers in Chemistry, 2023
Just as a single polypeptide strand can self-fold into a complex 3D structure, a single strand of DNA can self-fold into DNA origami. Most DNA origami structures (i.e., the scaffold-staple and DNA tiling systems) utilize hundreds of short single-stranded

Tiles with no spectra [PDF]

open access: yes, 2006
We exhibit a subset of a finite Abelian group, which tiles the group by translation, and such that its tiling complements do not have a common spectrum (orthogonal basis for their L-2 space consisting of group characters).

Randomness and Topological Invariants in Pentagonal Tiling Spaces

open access: yesDiscrete Dynamics in Nature and Society, 2011
We analyze substitution tiling spaces with fivefold symmetry. In the substitution process, the introduction of randomness can be done by means of two methods which may be combined: composition of inflation rules for a given prototile set and tile ...

Complexity of Tiling a Polygon with Trominoes or Bars [PDF]

open access: yes, 2017
We study the computational hardness of the tiling puzzle with polyominoes, where a polyomino is a rectilinear polygon (i.e., a polygon made by connecting unit squares.) In the tiling problem, we are given a rectilinear polygon P and a set S of ...

Dry sand as a specialized layer to improve the acoustic insulation between rooms one above another

open access: yesMateriales de Construccion, 2013
This work presents and analyses the experimental field results of the sound insulation from airborne and impact noise of the horizontal separating elements commonly used in the past, in which a uniform layer of sand was placed on top of the floor ...

The Symbolic Dynamics Of Multidimensional Tiling Systems [PDF]

open access: yes, 2003
We prove a multidimensional version of the theorem that every shift of finite type has a power that can be realized as the same power of a tiling system.
