Int erp retation of magneto telluri c data over inhomogeneous geolog­ ical st ructures is st ill a challenging problem in geophysical exploration. We have developed a new 3-D MT inversion method and a computer code based on full nonlinear conjugate gradient inversion and quasi­ analyt ical approximation for forward modeling solut ion. Appli cat ion of the QA approximation to forward model ing a...

A new approach for determining effective mechanical bondline properties using a combined experimental–numerical modal analysis technique is proposed. After characterizing clear spruce wood boards, an adhesive layer is applied to the boards’ surfaces. The shift of the eigenfrequencies resulting from the adhesive layer together with information on the bondline geometry can then be used to inverse...

This article is about the principles of NMR fluid typing referring to 1Dand 2D-NMR Laplace Invers Transform of the magnetization decay. NMR logs can provide useful information about the fluids located within the invaded zone of the near-wellbore volume, normally between one and five inches depth of investigation. The range of fluids that can be detected by NMR logs depends on the fact that the ...

Numerical solution of the Zakai equation usually leads to large systems of equations which have to be solved at each time step. An algorithm for the numerical approximation of the Zakai equation is presented, based on discretization schemes provided by Kushner, and by LeGland. We use an a posteriori criterion based on truncation error, to localize reenement regions. We apply the fast adaptive c...

Background Thermal component of the atmospheric environment is an important issue which is related to human's health. Thermal environment includes both heat exchange conditions (stress) and the physiological response (strain). The aim of this study was to measure the association of heat indices (PSI, HSI, Humidex) especially subjective one (STI) with some physiological parameters (Blood pressur...
