In a recent paper I have introduced a package for the exact simulation of power-law noises and other colored noises (E. Milotti, Comput. Phys. Commun. 175 (2006) 212): in particular the algorithm generates 1/f noises with 0 < α ≤ 2. Here I extend the algorithm to generate 1/f noises with 2 < α ≤ 4 (black noises). The method is exact in the sense that it produces a sampled process with a theoret...

We present a new formulation of the Mastrovito multiplication matrix for the field GF (2) generated by an arbitrary irreducible polynomial. We study in detail several specific types of irreducible polynomials, e.g., trinomials, all-one-polynomials, and equally-spaced-polynomials, and obtain the time and space complexity of these designs. Particular examples, illustrating the properties of the p...

Visualizing time series data is useful to support discovery of relations and patterns in financial, genomic, medical and other applications. In most time series, measurements are equally spaced over time. This paper discusses the challenges for unevenly-spaced time series data and presents four methods to represent them: sampled events, aggregated sampled events, event index and interleaved eve...
