1. The generalized anti-reflexive solutions for a class of matrix equations (BX = C, XD = E)
In this paper, the generalized anti-reflexive solution for matrix equations (BX = C, XD = E), which arise in left and right inverse eigenpairs problem, is considered. With the special properties of generalized anti-reflexive matrices, the necessary and sufficient conditions for the solvability and a general expression of the solution are obtained. Furthermor

2. EFFICIENCY ASSESSMENT OF ADVANCED MODAL ANALYSIS AS COMPARED TO TECHNIQUES BASED ON NUMERICAL INVERSE TRANSFORMS / COMPARAÇÃO DO DESEMPENHO COMPUTACIONAL DA TÉCNICA DE SUPERPOSIÇÃO MODAL AVANÇADA COM TÉCNICAS DA TRANSFORMADA DE LAPLACE
An established technique to solve time-dependent problems is the formulation of a complete frequency-domain analysis via Laplace or Fourier transforms, with subsequent ad hoc expression of results by numerical inversion. Although usually easy to implement, such a transform inversion is computationally intensive, if accurate results are desired, and liable to

3. CONVENTIONAL, HYBRID AND SIMPLIFIED BOUNDARY ELEMENT METHODS / MÉTODOS DE ELEMENTOS DE CONTORNO CONVENCIONAL, HÍBRIDOS E SIMPLIFICADOS
A consolidated, unified formulation of the conventional (CCBEM), hybrid stress (HSBEM), hybrid displacement (HDBEM) and simplified hybrid stress (SHSBEM) boundary element methods is presented. As a counterpart of SHSBEM, the simplified hybrid displacement boundary element method (SHDBEM) is proposed on the basis of the same stress and displacement approximat
