Dans le but de modéliser des populations dont la composition génétique suit une succession cyclique d'états d'équilibre, nous présentons une généralisation de la notion d'algèbre de Bernstein d'ordre n en introduisant la notion de périodicité.

Abstract:
The Bernstein Markov Property for a compact set E and a positive finite mea- sure μ supported on E is a strong comparability assumption between L μ 2 and uni- form norms on E of polynomials (or other nested families of functions) as their degree tends to infinity. Admissible meshes are sequences of sampling sets A k ⊂ E whose cardinality is growing sub-exponentially with respect to k and for which there exists a positive finite constant C such that max E |p| ≤ C max A k |p| for any polynomial of degree at most k. These two mathematical objects have several applications and motivations

Abstract:
This thesis deals mainly with geometric properties of generalized Bernstein polynomials which replace the single Bernstein polynomial by a one-parameter family of polynomials. It also provides a triangular decomposition and 1-banded factorization of the Vandermonde matrix. We first establish the generalized Bernstein polynomials for monomials, which leads to a definition of Stirling polynomials of the second kind. These are q-analogues of Stirling numbers of the second kind. Some of the properties of the Stirling numbers are generalized to their q-analogues. We show that the generalized Bernst

Introdotti originariamente all'inizio del '900 per risolvere il problema di approssimare una funzione continua su un intervallo chiuso e limitato della retta reale (Teorema di Stone-Weierstrass), essi hanno riscosso grande successo solo a partire dagli anni '60 quando furono applicati alla computer-grafica per costruire le cosiddette curve di Bezier.

The main aim of this thesis is the study of the Bernstein-Sato polynomial of plane curve singularities. In this context, we prove a conjecture posed by Yano about the generic b-exponents of a plane irreducible curve. In a part of the thesis, we study the Bernstein-Sato polynomial through the analytic continuation of the complex zeta function of a singularity. We obtain several results on the vanishing and non-vanishing of the residues of the complex zeta function. Using these results we obtain a proof of Yano's conjecture under the hypothesis that the eigenvalues of the monodromy are pair-w

Chlodovsky showed that if x₀ is a point of discontinuity of the first kind of the function f, then the Bernstein polynomials Bsubscript n](f, x₀) converge to the average of the one-sided limits on the right and on the left of the function f at the point x₀. In 2009, Telyakovskii in (5) extended the asymptotic formulas for the deviations of the Bernstein polynomials from the differentiable functions at the first-kind discontinuity points of the highest derivatives of even order and demonstrated the same result fails for the odd order case.

The ill-posed operations of greatest common divisor computations and polynomial division are considered, and it is shown that structure preserving matrix methods yield excellent results.

These are based on the Sylvester resultant matrix, and it is shown that a new form of the Sylvester r

Abstract:
Receiver operating characteristic (ROC) analysis is one of the most widely used methods in evaluating the accuracy of a classification method. It is used in many areas of decision making such as radiology, cardiology, machine learning as well as many other areas of medical sciences. The dissertation proposes a novel nonparametric estimation method of the ROC surface for the three-class classification problem via Bernstein polynomials. The proposed ROC surface estimator is shown to be uniformly consistent for estimating the tru

Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2005.<br>Includes bibliographical references (p. 333-340).<br>The steady-state confinement of tokamak plasmas in a fusion reactor requires non-inductively driven toroidal currents. Radio frequency waves in the electron cyclotron (EC) range of frequencies can drive localized currents and are thus particularly attractive for control of the current profile. In the high-[beta] regimes of spherical tokamaks (ST) such as NSTX and MAST, heating and current drive (CD) by conventional electron

Abstract:
This thesis focuses on the development of algorithms for the effiecient computation of the element system matrices associated with simplicial elements of arbitrary polynomial order. The algorithms make use of properties intrinsic to Bernstein-Bézier polynomials, allowing for sum factorizations techniques to be applicable. In particular, the presented algorithms are the first to achieve optimal complexity for H¹ elements on simplicial partitions in Rd, for d = 1, 2, 3. The optimal complexity result is extended to two-dimensional vector finite elements presents a clear distinction between the g

Abstract:
Neste trabalho estudamos algumas raízes do polinômio de Bernstein bf associado a um germe f(X) &#8712; &#8450;{X1,. . . , Xn} com ponto crítico isolado na origem. Sabe-se que, para cada raiz de bf, existe um número espectral tal que a soma desses dois números é um inteiro. Em geral, não se sabe exibir explicitamente esses números inteiros, embora existam cotas para eles. M. Saito [Sai93] exibe um subconjunto do conjunto das raízes de bf tal que para esses elementos a soma vale -1. Hertling e Stahlkc [IIS99] conseguiram aumentar esse subconjunto de raízes, supondo f(X) em duas variáveis, com p

Abstract:
Nos fins do século XIX, Eduard Bernstein causou grande espanto e turbulência no interior da social-democracia alemã ao refutar publicamente as teses oficiais propugnadas pelos líderes do partido e, ao mesmo tempo, propor a revisão crítica do pensamento de Marx, desferindo sérios ataques ao que considerava seu elemento \"nefasto\": a dialética hegeliana. Ao defender a rejeição da filosofia da história marxiana - considerada obstáculo ao conhecimento científico da realidade social - Bernstein rompe com a perspectiva revolucionária, aderindo a um reformismo evolucionista.

Abstract:
Le funzioni polinomiali possono essere utilizzate per approssimare le funzioni continue. Il vantaggio è che i polinomi, le loro derivate e primitive, possono essere rappresentati in maniera semplice attraverso i loro coefficienti ed esistono algoritmi stabili e veloci per valutarli. Inoltre gli spazi polinomiali godono di numerose proprietà importanti. In questo lavoro ci occuperemo di altri spazi funzionali, noti in letteratura come spazi di Chebyshev o polinomi generalizzati, per ragioni di riproducibilità. Infatti ciò che si ottiene attraverso i polinomi è soltanto una approssimazione che
