Some mathematical problems are simple to describe, however very difficult to solve. Integer factorization (e.g. 28=2x2x7) is one of them; apparently simple, it is exploited in the widely used RSA cryptography because there is no known... more
This document presents an evolved Girih tile set beyond the five Girih Tiles popularized by Lu and Steinhardt. Additional tiles have been presented in multiple papers before, but here, a wider set is officially defined. I refer to this as... more
Islamic geometric patterns can often be decomposed into a set of modular equilateral tiles, each decorated with a small motif, which assemble to form patterns. As the floodgate for tiles with additional side lengths was opened in the... more
This chapter examines the relationship between mathematics and textile knot practice, i.e., how mathematics may be adopted to characterize knotted textiles and to generate new knot designs. Two key mathematical concepts discussed are knot... more
I was curious what would happen if I applied the double crossing on the thin (Dia) and thick (Rhomb) rhombus from Penrose P3 tile set. Then I split the crossings into separate tiles and came up with two non-midpoint sets. At the time... more

Evolutionary studies usually assume that the genetic mutations are independent of each other. However, that does not imply that the observed mutations are independent of each other because it is possible that when a nucleotide is mutated,... more
Empirical program optimizers estimate the values of key optimization parameters by generating different program versions and running them on the actual hardware to determine which values give the best performance. In contrast,... more
This paper proposes a family of origami tessellations called extruded Miura-Ori, whose folded state lies between two parallel planes with some faces on the planes, potentially useful for folded core materials because of face bonding. An... more
This is my third paper submitted to the Bridges Conference. Unfortunately it was rejected, and the reasons given by the reviewers was perfectly valid. The case being that this topic is too big to fit into the page limitation of eight... more
We survey existing methods for counting two-cell tilings of finite planar lattice regions. We provide the only proof of the Pfaffian-squared theorem the author is aware of which is simultaneously modern, elementary, and fully correct.... more
The projection method for constructing quasiperiodic tilings from a higher dimensional lattice provides a useful context for computing a quasicrystal's vertex configurations, frequencies, and empires (forced tiles). We review the... more
Editorial introduction to a special double issue of the Journal of Mathematics and the Arts 12/2-3 (2018). Reza Sarhangi (1952-2016), as a mathematician, educator, and artist, had a profound impact on many interdisciplinary approaches to... more

Children of different classes of elementary schools in Portugal have participated in a mathematics pro ject which aims at increasing the interest for Mathematics in Portugal together with developing skills for day-to -day problem solving... more
Laddove i progressi nel campo della tecnologia dell'immagine rendono disponibili monitor, schermi e touch-screen con risoluzione sempre maggiore-nei quali la misura di ogni singolo pixel sembra ridursi sino alla soglia della effettiva... more
We propose a software architecture for picture processing with three objectives. Images are represented as a set of tiles that are computed on demand, i.e. when needed as arguments to some operator. An image is indeed an operator instance... more

By sharing processor resources among threads at a very fine granularity, a simultaneous multithreading processor (SMT) renders thread-level parallelism (TLP) and instruction-level parallelism (ILP) operationally equivalent. Under what... more
this paper discusses the selection of an optimal supernode shape of a supernode transformation (also known as tiling). We assume that the communication cost is dominated by the startup penalty and therefore, can be approximated by a... more
Pasting Scheme is a generating model for Tiling and Tessellation pattern. Truchet tiles are special type of tiles with continuous arc. In this paper the pasting scheme model is used to study the construction of triangle shaped Truchet... more

This paper explores patterns of particular variations of Truchet tiles that consist of arcs combined with squares and regular hexagons. With the help of matrixes with boolean values and observation of patterns in random tessellations the... more
— We present a new basis for analysis of music. The basis vectors are sampled real waveforms of fixed frequency inside a Gaussian envelope. Their frequencies and time localizations are induced by a tiling of the time-frequency plane well... more
Tiling improves the artistic appeal of many rooms’ floors and walls. However, it is necessary to take precautions to prevent the tiles from deteriorating over time. This is especially in wet or moisture-prone areas like the bathroom.... more
We all know how frustrating it is to see leaking tiles in the bathroom. The feeling of wanting to retain the bathroom tile, but wanting to repair it poses a dilemma. In most cases, due to lack of ideas on how to address the tiling issue... more
