The average state complexity of rational operations on finite languages is linear

2010

Considering the uniform distribution on sets of m non-empty words whose sum of lengths is n, we establish that the average state complexities of the rational operations are asymptotically linear.

INTERNAL AUDIT: DEFINING, OBJECTIVES, FUNCTIONS AND STAGES

2010

This article aims, through a detailed presentation as to provide clarification for a better understanding of what internal audit definition, objectives, functions and stages of its development mean. It is also exposed a brief history about the emergence and development of internal audit and regulatory framework. I also plan to linking theory and practice by reference to documents used: both the evidence considered and especially those prepared by the auditors in connection with the performance audit and its use in the audit report.

Electrocardiographic Imaging Using a Spatio-Temporal Basis of Body Surface Potentials—Application to Atrial Ectopic Activity

2018

Electrocardiographic imaging (ECGI) strongly relies on a priori assumptions and additional information to overcome ill-posedness. The major challenge of obtaining good reconstructions consists in finding ways to add information that effectively restricts the solution space without violating properties of the sought solution. In this work, we attempt to address this problem by constructing a spatio-temporal basis of body surface potentials (BSP) from simulations of many focal excitations. Measured BSPs are projected onto this basis and reconstructions are expressed as linear combinations of corresponding transmembrane voltage (TMV) basis vectors. The novel method was applied to simulations o…

Liturgia śląskich kanoników regularnych w średniowieczu

2016

In Medieval Silesia there were two convents o f the Canons Regular: in Wrocław and in Żagań. Their mother-monastery was the abbey in Arrovaise (Flanders). As every order, the Canons Regular had theirs own liturgical customs, in this case borrowed from Arrovai.se. These customs were practised in Silesia at least until the second h alf o f the 14th century, when they started to resemble m ore and m ore the diocesans practices. This phenomenon was particularly noticeable in the 15th century. A t that time, on one hand, we deal with the introduction of the inner-convents reforms, which aimed to elaborate the new statutes. On the other, we also deal with the willingness to enhance the liturgy by…

Yearly quotas and country-reserved shares in Italian immigration policy

2008

Regular immigration to Italy is based on a quota system setting annual ceilings to legal entries. Reserved shares are granted to single countries or categories of countries. Reserved shares have been increased; they are used as an incentive to obtain the cooperation of countries of origin in stemming irregular migration flows. The total quota of regular immigration has gradually increased too. Still, it does not fully respond to the growing demand of foreign workers on the labour market, and quotas seem to be used as crypto-regularisations rather than as an instrument for regulating legal entries.

Increasing Stability of EEG Components Extraction Using Sparsity Regularized Tensor Decomposition

2018

Tensor decomposition has been widely employed for EEG signal processing in recent years. Constrained and regularized tensor decomposition often attains more meaningful and interpretable results. In this study, we applied sparse nonnegative CANDECOMP/PARAFAC tensor decomposition to ongoing EEG data under naturalistic music stimulus. Interesting temporal, spectral and spatial components highly related with music features were extracted. We explored the ongoing EEG decomposition results and properties in a wide range of sparsity levels, and proposed a paradigm to select reasonable sparsity regularization parameters. The stability of interesting components extraction from fourteen subjects’ dat…

(p,2)-equations resonant at any variational eigenvalue

2018

We consider nonlinear elliptic Dirichlet problems driven by the sum of a p-Laplacian and a Laplacian (a (p,2) -equation). The reaction term at ±∞ is resonant with respect to any variational eigenvalue of the p-Laplacian. We prove two multiplicity theorems for such equations.

Solutions with sign information for nonlinear Robin problems with no growth restriction on reaction

2019

We consider a parametric nonlinear Robin problem driven by a nonhomogeneous differential operator. The reaction is a Carathéodory function which is only locally defined (that is, the hypotheses concern only its behaviour near zero). The conditions on the reaction are minimal. Using variational tools together with truncation, perturbation and comparison techniques and critical groups, we show that for all small values of the parameter λ > 0, the problem has at least three nontrivial smooth solutions, two of constant sign and the third nodal.

Encoding specificity instead of online integration of real-world spatial regularities for objects in working memory

2022

Most objects show high degrees of spatial regularity (e.g. beach umbrellas appear above, not under, beach chairs). The spatial regularities of real-world objects benefit visual working memory (VWM), but the mechanisms behind this spatial regularity effect remain unclear. The "encoding specificity" hypothesis suggests that spatial regularity will enhance the visual encoding process but will not facilitate the integration of information online during VWM maintenance. The "perception-alike" hypothesis suggests that spatial regularity will function in both visual encoding and online integration during VWM maintenance. We investigated whether VWM integrates sequentially presented real-world obje…
