1. Identidades polinomiais graduadas de algumas àlgebras matriciais
Let K be an associative and commutative ring with 1 and let A be an associative Kalgebra with or without 1. We say that the polynomial identities of A have the Specht property if each K-algebra B satisfying all the polynomial identities of A has a finite basis for its identities. Let M2(K) be the algebra of 2 × 2 matrices over a field K. If K is a field of

2. Sistema de identidades polinomiais sem base finita
Let F be a field and let A be the free associative F-algebra (without 1) on free generators x1; x2; Let f = (x1;; xn) A and let G be an associative algebra over F. We say that f = 0 is a polynomial identity (or an identity) in G if f(g1; ; gn) = 0 for all g1; ; gn G. Two systems of polynomial identities {ui = 0}| i I} and {vj = 0} | j J} are equivalent if ev

3. Studies on Barlow points, Gauss points and Superconvergent points in 1D with Lagrangian and Hermitian finite element basis
In this work, we consider the superconvergence property of the finite element derivative for Lagrange's and Hermite's Family elements in the one dimensional interpolation problem. We also compare the Barlow points, Gauss points and Superconvergence points in the sense of Taylor's Series, confirming that they are not the same as believed before. We prove a no

4. Damage detection in complex structures using Component Mode Synthesis and Ritz vectors / Detecção de falhas em estruturas complexas usando sintese modal dos componentes e vetores de Ritz
This work explores the use of Component Mode Synthesis methods (CMS), Minimum Rank Perturbation Theory (MRPT), and Ritz Realization AIgorithm (RRA) as a structural damage detection tooI. The CMS consists in to modeling individual components of a structure separately and then to couple them to form an assembled system. CMS methods can be generalized to allow
