Stack Sorting with Increasing and Decreasing Stacks [PDF]
The Electronic Journal of Combinatorics, 2020 We introduce a sorting machine consisting of $k+1$ stacks in series: the first $k$ stacks can only contain elements in decreasing order from top to bottom, while the last one has the opposite restriction. This device generalizes the $\mathfrak{DI}$ machine introduced by Rebecca Smith, which studies the case $k=1$.

A comparison of strategies to extend the operating range of radial compressors for turbocharging [PDF]
E3S Web of Conferences, 2023 The operating range extension of radial compressors is a crucial aspect in turbocharging the internal combustion engines in order to extend the operating range of the system at high efficiency for fuel and environmental impact reduction.

Sorting and preimages of pattern classes [PDF]
Discrete Mathematics & Theoretical Computer Science, 2012 We introduce an algorithm to determine when a sorting operation, such as stack-sort or bubble-sort, outputs a given pattern. The algorithm provides a new proof of the description of West-2-stack-sortable permutations, that is permutations that are ...

Troupes, cumulants, and stack-sorting [PDF]
Advances in Mathematics, 2022 Several sequences of free cumulants that count binary plane trees correspond to sequences of classical cumulants that count the decreasing versions of the same trees. Using two new operations on colored binary plane trees that we call insertion and decomposition, we prove that this surprising phenomenon holds for families of trees that we call troupes.

Sorting with Pattern-Avoiding Stacks: The 132-Machine [PDF]
The Electronic Journal of Combinatorics, 2020 This paper continues the analysis of the pattern-avoiding sorting machines recently introduced by Cerbai, Claesson and Ferrari (2020). These devices consist of two stacks, through which a permutation is passed in order to sort it, where the content of each stack must at all times avoid a certain pattern.
