In a mixture experiment the collinearity problems, implied by the sum to one functional
relationship among the factors, have strong consequences on the identification and analysis of …

We prove that the number of Hamiltonian paths on the complement of an acyclic digraph is
equal to the number of cycle covers. As an application, we obtain a new expansion of the …

The Tutte polynomial is one of the most important and most useful invariants of a graph. It was
discovered as a two variable generalization of the chromatic polynomial [15, 16], and has …

^''Neferet va a enfrentarse muy pronto con la última prueba antes de poder ejercer su arte-recordó
Branir-; por eso repasamos los ejercicios al hacer su diagnóstico. Estoy convencido …

En esta Tesis se presenta una metodología de análisis basada en la aritmética de intervalos
y sus extensiones para calcular los efectos de cuantificación en uno de los sistemas …

Experiments with mixture and process variables are often constructed as the cross product
of a mixture and a factorial design. Often it is not possible to implement all the runs of the …

Fixed a set of finitely many segments in Rd we look for a connected system of these segments
whose convex hull has the greatest d-dimensional volume, solving the problem when d …

Given a convex body $$ C \subseteq \mathbb{R}^d $$ and a positive real λ, any set of the
form λC +x = {λc+x ∣ c ∈ C} for some x ∈ ℝ d is called a homothetic copy (or, briefly, a …

Starting from some studies of (linear) integer partitions, we noticed that the lattice structure
is strongly related to a large variety of discrete dynamical models, in particular sandpile …

In this paper, a new approach to worst-case simulation of discrete linear time- invariant interval
dynamic systems is proposed. For stable systems, the new approach solves the problem …
