A new condition for identifiability of finite mixture distributions
(Springer, 2006)
In this paper a sufficient condition for the identifiability of finite mixtures is given. This condition is less restrictive than Teicher’s condition (Teicher H, Ann Math Stat 34:1265–1269 (1963)) and therefore it can ...

The de la Vallée-Poussin theorem and Orlicz spaces associated to a vector measure
(Elsevier, 2019)
For a vector measure m, with values in a Banach space, we analyze the localization of uniformly integrable subsets of scalar integrable functions with respect to m in a suitable Orlicz space associated to m. As tools we ...

Uniformly Summing Sets of Operators on Spaces of Continuous Functions
(Hindawi, 2004)
Let X and Y be Banach spaces. A set ℳ of 1-summing operators from X into Y is said to be uniformly summing if the following holds: given a weakly 1-summing sequence (xn) in X, the series ∑n‖Txn‖ is uniformly convergent in ...

A Weakly Non-hydrostatic Shallow Model for Dry Granular Flows
(Springer, 2021)
A non-hydrostatic depth-averaged model for dry granular flows is proposed, taking into account vertical acceleration. A variable friction coefficient based on the μ(I) rheology is considered. The model is obtained from ...

An approach to the isotheory by means of extended pseudoisotopisms
(American Institute of Physics, 2016)
Based on the traditional concept of isotopism, extended isotopisms were introduced by the authors in 2006 in order to provide a fundamental basis to the isotheory of Santilli. Since that first attempt, distinct studies on ...

Simplicial-Map Neural Networks Robust to Adversarial Examples
(MDPI [Commercial Publisher], 2021-01-15)
Broadly speaking, an adversarial example against a classification model occurs when a small perturbation on an input data point produces a change on the output label assigned by the model. Such adversarial examples represent ...

A note on real interpolation of L-P-spaces of vector measures on delta-rings
(Elsevier, 2014)
We describe the real interpolation spaces obtained when we apply the real K-method of Lions–Peetre to Banach lattices of p-integrable and weakly p-integrable functions with respect to a Banach-space-valued measure defined ...

An MPI-CUDA implementation of an improved Roe method for two-layer shallow water systems
(Elsevier, 2012)
The numerical solution of two-layer shallow water systems is required to simulate accurately stratified fluids, which are ubiquitous in nature: they appear in atmospheric flows, ocean currents, oil spills, . . . Moreover, ...

Generating binary partial Hadamard matrices
(Elsevier, 2019)
This paper deals with partial binary Hadamard matrices. Although there is a fast simple way to generate about a half (which is the best asymptotic bound known so far, see de Launey (2000) and de Launey and Gordon (2001)) ...

On quasi-orthogonal cocycles
(Wiley, 2017)
We introduce the notion of quasi-orthogonal cocycle. This is motivated in part by the maximal determinant problem for square {±1}-matrices of size congruent to 2 modulo 4. Quasi-orthogonal cocycles are analogous to the ...
