conclusions this study highlights the close link between the role of the phrenic nerve and pulmonary function, such that the use of this nerve as a transfer donor leads to spirometric impairments. results all patients regained biceps power to m3 strength or above. none of our patients experienced pulmonary problems or respiratory complaints, but a significant reduction of spirometric parameters...

Résumé : Nous étudions dans cet article des algorithmes de calcul de la réduction de Hermite d'une matrice a coefficients polynomiaux, qui évitent l'explosion de la taille des objets intermédiaires et ont une bonne complexité séquentielle. Le deuxième et le troisième algorithmes généralisent la méthode des sous-résultants pour le calcul du pgcd de deux polynomes. Le dernier de ces algorithmes s...

Many problems in the theory of sparse approximation require bounds on operator norms of a random submatrix drawn from a fixed matrix. The purpose of this note is to collect estimates for several different norms that are most important in the analysis of `1 minimization algorithms. Several of these bounds have not appeared in detail. Résumé Sur la norme de sous-matrice tirée aléatoirement. Beauc...

In this article, a special type of orthogonalization is obtained to construct a multiple input transfer function model. By using this technique, construction of a transfer function model is divided to sequential construction of transfer function models with less input time series. Furthermore, based on real and simulated time series we provide an instruction to adequately perform the stages of ...

Let A be a matrix whose columns X1, . . . , XN are independent random vectors in R. Assume that p-th moments of 〈Xi, a〉, a ∈ Sn−1, i ≤ N , are uniformly bounded. For p > 4 we prove that with high probability A has the Restricted Isometry Property (RIP) provided that Euclidean norms |Xi| are concentrated around √ n and that the covariance matrix is well approximated by the empirical covariance m...

Les propos au sujet de l’œuvre gravé Nathalie Grall soulignent son pouvoir onirique, poétique, ses qualités scripturales. Ici sera pointée la place toute centrale matrice, dans le concret l’expérience l’atelier, sensible aux signes peints comme incisions qu’ils préfigurent. Aussi, l’aval gravure, celle-ci conçue, il arrive régulièrement, depuis début des années 2000, que les possibilités plaque...

It is shown that a nondegenerate square real matrix M is a P-matrix if and only if, whatever is the real vector q, the Newton-min algorithm does not cycle between two points when it is used to solve the linear complementarity problem 0 6 x ⊥ (Mx+ q) > 0. Key-words: Linear complementarity problem, semismooth Newton method, Newton-min algorithm, NM-matrix, P-matricity characterization, P-matrix. ...

in this paper, a new algorithm for system identification based on frequency response is presented. in this method, given a set of magnitudes and phases of the system transfer function in a set of discrete frequencies, a system of linear equations is derived which has a unique and exact solution for the coefficients of the transfer function provided that the data is noise-free and the degrees of...
