On the Generating Function for Intervals in Young's Lattice

open access: yesThe Electronic Journal of Combinatorics, 2023
In this paper, we study a family of generating functions whose coefficients are polynomials that enumerate partitions in lower order ideals of Young's lattice. Our main result is that this family satisfies a rational recursion and are therefore rational functions.

A Novel Approach for Simplification of Industrial Robot Dynamic Model Using Interval Method [PDF]

open access: yes, 2014
This paper proposes a new approach to simplify the dynamic model of industrial robot by means of interval method. Due to strong nonlinearities, some components of robot dynamic model such as the inertia matrix and the vector of centrifugal, Coriolis and ...

Dynamics of non-classical interval exchanges [PDF]

open access: yes, 2010
A natural generalization of interval exchange maps are linear involutions, first introduced by Danthony and Nogueira [Measured foliations on non-orientable surfaces. Ann. Sci. Éc. Norm. Supér. (4) 26(6) (1993), 645–664].

Preferences on Intervals: a general framework

open access: yes, 2005
I present a general framework for the comparison of alternatives to which (possibly) an interval of values is associated. Some representation theorems for the existence of the intervals are discussed as well the possibility ot explicitly take into account situations of hesitation. Some appropriate logical formalisms are discussed for such a purpose.

Investigating the relation between optimum guard interval and channel delay spread for a MC-CDMA system [PDF]

open access: yes, 2012
This paper demonstrates a novel approach to determining the optimum guard interval for a multicarrier code division multiple access (MC-CDMA) system. Analytical expressions for useful and interference power are derived as a basis for comparison.

A general method for common intervals

open access: yesCoRR, 2013
Given an elementary chain of vertex set V, seen as a labelling of V by the set {1, ...,n=|V|}, and another discrete structure over $V$, say a graph G, the problem of common intervals is to compute the induced subgraphs G[I], such that $I$ is an interval of [1, n] and G[I] satisfies some property Pi (as for example Pi= "being connected").

Population structure of the Trakehner Horse breed

open access: yesAnimal, 2009
The objective of this study was to examine the population structure of the Trakehner Horse breed. A total of 13 793 pedigree records were used for analysing the active breeding population and their ancestors dating back to 1950.
