Distribution of the Number of Encryptions in Revocation Schemes for Stateless Receivers [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
We study the number of encryptions necessary to revoke a set of users in the complete subtree scheme (CST) and the subset-difference scheme (SD). These are well-known tree based broadcast encryption schemes.

Teaching Combinatorial Principles Using Relations through the Placemat Method

open access: yesMathematics, 2021
The presented paper is devoted to an innovative way of teaching mathematics, specifically the subject combinatorics in high schools. This is because combinatorics is closely connected with the beginnings of informatics and several other scientific ...

Data‐Driven Review and Machine Learning Prediction of Diamond Vacancy Center Synthesis

open access: yesAdvanced Intelligent Systems, EarlyView.
A machine learning framework is applied to photoluminescence spectra to extract linewidths and uncover how NV, SiV, GeV, and SnV centers evolve with growth and processing conditions. Unified normalization and k‐fold validation reveal cross‐method trends and enable rapid prediction of defect size and fabrication parameters, offering a data‐driven route ...

Kaleidoscopic Edge-Coloring of Complete Graphs and r-Regular Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2019
For an r-regular graph G, we define an edge-coloring c with colors from {1, 2, . . . , k}, in such a way that any vertex of G is incident with at least one edge of each color. The multiset-color cm(v) of a vertex v is defined as the ordered tuple (a1, a2,

List circular backbone colouring [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2014
A natural generalization of graph colouring involves taking colours from a metric space and insisting that the endpoints of an edge receive colours separated by a minimum distance dictated by properties of the edge.

Bayesian Optimisation for the Experimental Sciences: A Practical Guide to Data‐Efficient Optimisation of Laboratory Workflows

open access: yesAdvanced Intelligent Systems, EarlyView.
This study provides an introduction to Bayesian optimisation targeted for experimentalists. It explains core concepts, surrogate modelling, and acquisition strategies, and addresses common real‐world challenges such as noise, constraints, mixed variables, scalability, and automation.

Generalized Rainbow Connection of Graphs and their Complements

open access: yesDiscussiones Mathematicae Graph Theory, 2018
Let G be an edge-colored connected graph. A path P in G is called ℓ-rainbow if each subpath of length at most ℓ + 1 is rainbow. The graph G is called (k, ℓ)-rainbow connected if there is an edge-coloring such that every pair of distinct vertices of G is ...

On the Rainbow Vertex-Connection

open access: yesDiscussiones Mathematicae Graph Theory, 2013
A vertex-colored graph is rainbow vertex-connected if any two vertices are connected by a path whose internal vertices have distinct colors. The rainbow vertex-connection of a connected graph G, denoted by rvc(G), is the smallest number of colors that ...

Coxeter-biCatalan combinatorics [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2015
We consider several counting problems related to Coxeter-Catalan combinatorics and conjecture that the problems all have the same answer, which we call the $W$ -biCatalan number. We prove the conjecture in many cases.

Alexander Duality and Rational Associahedra [PDF]

open access: yes, 2013
A recent pair of papers of Armstrong, Loehr, and Warrington and Armstrong, Williams, and the author initiated the systematic study of {\em rational Catalan combinatorics} which is a generalization of Fuss-Catalan combinatorics (which is in turn a ...
