In the present paper, we aim to constrain properties of ionisation region in a star from oscillation frequency variation (a so-called glitch) caused by rapid structural variations this very region. particular, seek avoid use calibration based on stellar models thus providing truly independent estimate these properties. These include both helium abundance and other physical quantities that can h...

Since the appearance of first modern multistories buildings, besides demand ensuring bearing capacity, one urgent problems facing engineer is to do how design structure ensure requirements normal use such as displacement, motion acceleration within permissible limits. There exist many methods reduce these response under lateral load. Among these, using fluid viscous damper (FVD) most applied eq...

The fuzzy logic concept provides a natural way of dealing with problems in which the source of imprecision is an absence of sharply defined criteria rather than the presence of random variables. The fuzzy approach considers cases where uncertainties play a role in the control mechanism of the concerned phenomena. Fuzzy modeling includes fuzzification, fuzzy analysis and defuzzification. In this...

With the fast development of Visualization Technology, massive data need to be converted into intuitive graphics in more and more areas, such as in oil and geological exploration fields. In order to achieve highly efficient visualization of 2D seismic data, the following important methods are employed to improve the speed of rendering. The first method is to process massive data in point coordi...

Imaging highly complex subsurface structures is a challenging problem because it ultimately necessitates dealing with nonlinear multiple-scattering effects (e.g., migration of multiples, amplitude corrections for transmission effects) to overcome the liminations of linear imaging. Most of the current migration techniques rely on the linear single-scattering assumption, and therefore, fail to ha...

The concept of controlling seismic waves is in progress and first full-scale experiments had confirmed the interest which we can have for this new axis of research. The possibility of imagining a seismic 2D or 3D metamaterial made of a grid of inclusions or empty boreholes in the soil, interacting with a part of the earthquake signal is becoming realistic. Here we show the dynamic response of a...
