Ohne Frage? Mit Sicherheit. Präpositionale Wortverbindungen als Ausdrucksformen der Sprechereinstellung / Ohne Frage? Mit Sicherheit. Preposition-noun Phrases as Expressive Form of Speaker Attitude [PDF]

open access: yesLinguistische Treffen in Wrocław, 2020
Usualisierte Mehrworteinheiten stellen ein breites, strukturell und semantisch sehr heterogenes Spektrum von sprachlichen Elementen dar. Das Thema des Beitrags fokussiert die Problematik der lexikalisch-syntagmatischen Kombinatorik von usuellen ...

Frequency-Hopping Sequences With Optimal Average Hamming Correlation and Their Applications in Energy and Spectrum Harvesting Technologies Area

open access: yesIEEE Access, 2021
The research of cyclotomy theory can be traced to Gauss and it has been applied to many fields such as cryptography, coding theory, and combinatorics. According to $v$ prime numbers or compound words, the incision on the residue-like ring ${\mathbb Z ...

Subproduct systems and Cartesian systems; new results on factorial languages and their relations with other areas [PDF]

open access: yes, 2020
We point out that a sequence of natural numbers is the dimension sequence of a subproduct system if and only if it is the cardinality sequence of a word system (or factorial language).

On the Entropy of a Two Step Random Fibonacci Substitution

open access: yesEntropy, 2013
We consider a random generalization of the classical Fibonacci substitution. The substitution we consider is defined as the rule mapping, a → baa and b → ab, with probability , and  → ba, with probability 1 – p for 0 < p < 1, and where the random rule is

How often do we reject a superior value? (Extended abstract) [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2011
Words $a_1 a_2 \ldots a_n$ with independent letters $a_k$ taken from the set of natural numbers, and a weight (probability) attached via the geometric distribution $pq^{i-1}(p+q=1)$ are considered.

Multicollision attacks and generalized iterated hash functions

open access: yesJournal of Mathematical Cryptology, 2010
We apply combinatorics on words to develop an approach to multicollisions in generalized iterated hash functions. Our work is based on the discoveries of A. Joux and on generalizations provided by M. Nandi and D. Stinson as well as J. Hoch and A. Shamir.

Analysis of the multiplicity matching parameter in suffix trees [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2005
In a suffix tree, the multiplicity matching parameter (MMP) $M_n$ is the number of leaves in the subtree rooted at the branching point of the $(n+1)$st insertion.

Counting words with Laguerre polynomials [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2013
We develop a method for counting words subject to various restrictions by finding a combinatorial interpretation for a product of formal sums of Laguerre polynomials.

Computing Maximal Lyndon Substrings of a String

open access: yesAlgorithms, 2020
There are two reasons to have an efficient algorithm for identifying all right-maximal Lyndon substrings of a string: firstly, Bannai et al. introduced in 2015 a linear algorithm to compute all runs of a string that relies on knowing all right-maximal ...
