EBTM: An Enumeration-Based Thresholding Method for Degraded Circular Dot Segmentation [PDF]
SensorsCircular dots are widely used in various measurement applications due to their inherent symmetry, ease of detection, and scalability. However, when degraded by factors such as specular highlights, low contrast, strong noise, or friction damage ...

Enumerating Finitary Processes. [PDF]
Entropy (Basel)We show how to efficiently enumerate a class of finite-memory stochastic processes using the causal representation of ϵ-machines. We characterize ϵ-machines in the language of automata theory and adapt a recent algorithm for generating accessible deterministic finite automata, pruning this over-large class down to that of ϵ-machines. As an application,

A generalization of the quadrangulation relation to constellations and hypermaps [PDF]
Discrete Mathematics & Theoretical Computer Science, 2013 Constellations and hypermaps generalize combinatorial maps, $\textit{i.e.}$ embedding of graphs in a surface, in terms of factorization of permutations.

A bijection between planar constellations and some colored Lagrangian trees [PDF]
Discrete Mathematics & Theoretical Computer Science, 2003 Constellations are colored planar maps that generalize different families of maps (planar maps, bipartite planar maps, bi-Eulerian planar maps, planar cacti, ...) and are strongly related to factorizations of permutations.

Counting the Undercounted: Enumerating Rural Homelessness in Canada
International Journal on Homelessness, 2022 Until recently, homelessness in Canada was largely considered to be an urban phenomenon. This assumption has been reinforced by homelessness interventions that primarily focus on urban areas.
