Codes between MBR and MSR Points with Exact Repair Property
Toni Ernvall
In this paper distributed storage systems with exact repair are studied. A construction for regenerating codes between the minimum storage regenerating (MSR) and the minimum bandwi…
Constructions with Countable Subshifts of Finite Type
Ville Salo, Ilkka Törmä
We present constructions of countable two-dimensional subshifts of finite type (SFTs) with interesting properties. Our main focus is on properties of the topological derivatives an…
Playing with Subshifts
Ville Salo, Ilkka Törmä
We study the class of word-building games, where two players pick letters from a finite alphabet to construct a finite or infinite word. The outcome is determined by whether the re…
Category Theory of Symbolic Dynamics
Ville Salo, Ilkka Törmä
We study the central objects of symbolic dynamics, that is, subshifts and block maps, from the perspective of basic category theory, and present several natural categories with sub…
From Bits to Atoms: 3D Printing in the Context of Supply Chain Strategies
Henrik J Nyman, Peter Sarlin
A lot of attention in supply chain management has been devoted to understanding customer requirements. What are customer priorities in terms of price and service level, and how can…
Cluster coloring of the Self-Organizing Map: An information visualization perspective
Peter Sarlin, Samuel Rönnqvist
This paper takes an information visualization perspective to visual representations in the general SOM paradigm. This involves viewing SOM-based visualizations through the eyes of…
