Fictive Axis Emulator-based State Feedback Vector Current Control for Single-Phase Voltage Source Converters

This paper presents a vector current control method tailored for single-phase voltage source converters. In order to imitate the behavior of a three-phase system, the Fictive Axis Emulation (FAE) concept is employed. The latter is able to synthesize the ro ...

Modelling brain cortical connectivity using diffusion adaptation

Ali H. Sayed

This work examines the flow of information among electrodes attached to the brain and uses diffusion adaptation strategies to assess brain cortical connectivity. The method uses the directed transfer function (DTF) technique to estimate combination coeffic ...

MATHICSE Technical Report : Sparse spectral approximations for computing polynomial functionals

Fabio Nobile

We give a new fast method for evaluating sprectral approximations of nonlinear polynomial functionals. We prove that the new algorithm is convergent if the functions considered are smooth enough, under a general assumption on the spectral eigenfunctions th ...

Active Learning of Multi-Index Function Models

Volkan Cevher, Hemant Tyagi

We consider the problem of actively learning \textit{multi-index} functions of the form

f(x) = g(Ax)= \sum_{i=1}^k g_i(a_i^Tx)

from point evaluations of

f

. We assume that the function

f

is defined on an

\ell_2

-ball in

\Real^d

g

is twice contin ...

Application of the Matrix Pencil Method to Rational Fitting of Frequency-Domain Responses

Mario Paolone, Hamidreza Karami, Keyhan Sheshyekani

This paper presents a general methodology based on the matrix pencil method (MPM) for the fitting of frequency-domain responses in order to be properly represented in time-domain analysis. By virtue of the proposed method, a rational fitting of the frequen ...

Lessivage des polluants urbains et changement climatique : l’influence des modèles

David Andrew Barry, Luca Rossi, Sylvain Coutu, Sébastien Kramer

Rainfall for the next century will be influenced by global warming. These modified rainfalls will have influences on rainfall runoff. In order to analyze these impacts, this study compared different buildup and washoff functions with several future rainfal ...

Black-box optimization benchmarking of IPOP-saACM-ES and BIPOP-saACM-ES on the BBOB-2012 noiseless testbed

Ilya Loshchilov

In this paper, we study the performance of IPOP-saACM-ES and BIPOP-saACM-ES, recently proposed self-adaptive surrogate-assisted Covariance Matrix Adaptation Evolution Strategies. Both algorithms were tested using restarts till a total number of function ev ...

Improved Recognition of Error Related Potentials through the use of Brain Connectivity Features

José del Rocio Millán Ruiz, Ricardo Andres Chavarriaga Lozano, Huaijian Zhang, Lucian Andrei Gheorghe, Mohit Kumar Goel

Abstract—Brain error processing plays a key role in goaldirected behavior and learning in human brain. Directed transfer function (DTF) on EEG signal brings unique features for discrimination between correct and error cases in braincomputer interface (BCI) ...

Functions With Orthogonal Hessian

Bernard Dacorogna

A Dirichlet problem for orthogonal Hessians in two dimensions is explicitly solved, by characterizing all piecewise C-2 functions u Omega subset of R-2 -> R with orthogonal Hessian in terms of a property named "second order angle condition" as in (1 1) ...
