Existence and construction of the solutions of some Markov moment problems are discussed. Starting from the moments of a solution, one recalls a method of recovering this solution, also solving approximately related systems with infinite many nonlinear eq... see more

No fim dos anos 1980, consolida-se o discurso atualmente ainda hegemônico a respeito da crise ambiental, por meio da categoria de “sustentabilidade”. Elaborada no relatório Brundtland, a sustentabilidade tem como corolário o avanço tecnológico como a prin... see more

In this paper we present a new study on the High Tiber Valley earthquake occurred on April 26, 1917. Using the digitized data from mechanical seismograph records, we computed the source parameters like focal mechanism and moment magnitude from moment tens... see more

Step by step process solution matrix moment problem on a compact interval has been considered. Explicit formulas for generalized Schur parameters has been obtained.

Based on the laws of conservation of mass and momentum the basic equations of motion with unknown quantities velocity and piezometric pressure are written. These equations are supplemented with boundary and initial conditions describing the motion of comp... see more

Problems of documentation in archaeologyWhen documentation is spoken of in connection with archaeology, it is usually in the sense of the presentation of proof for the interpretation of observations made during excavation or during the study of artefacts,... see more

The shear (SH)-wave transfer function and the horizontal-to-vertical (HV) spectral ratio are essential to estimate the S-wave velocity pro- le and thickness of surface layers overlying a bedrock on the basis of resonance frequencies. In practice, it is th... see more
