Our study aimed to find a mechanism that controls preparation and subsequent full seismic activation of large faults that may act as sources of strong earthquakes. A large fault was physically modeled to investigate the dynamics of its deformation. The experiments were conducted on elastoviscoplasti...

The modification of a dynamic physical clarinet model based on a digital waveguide is presented in the paper. In particular, the influence of the output filter parameters on the signals generated by the model was investigated. As the output filter, the adaptive filter was designed and implemented wi...

Introduction. Clearing the territories of populated areas from fallen snow in winter is an urgent task. Its effective solution is necessary to ensure road safety and mobility. From the point of view of environmental safety, it is expedient not to remove the collected snow to special landfills, but t...

In recent years, the analysis of the dependence of reflection coefficients on the magnitude of the angle of incidence of reflected waves has been successfully used in the practice of seismic research. AVO analysis is one of the methods of dynamic analysis that is used to estimate changes in the ampl...

Modes of «dry friction» at glacier-bedrock interface (ice sliding and flow) were simulated under uniform compression with different combinations of mechanical and thermodynamic factors. Effect of ice structure in the intermediate layer was considered in terms of strength of ice adhesion to complex-s...

Results of uniaxial compression tests of rock samples in electromagnetic fields are presented. The experiments were performed in the Laboratory of Basic Physics of Strength, Institute of Continuous Media Mechanics, Ural Branch of RAS (ICMM). Deformation of samples was studied, and acoustic emission...

The possibility of glacier ice flow studies using the method of acoustic emission (AE) in frequency range from 15 Hz to 20 kHz has been considered. A portable acoustic line system has been developed and a number of methodological issues (mounting of acoustic sensors into glacial ice, their location,...

As oil reserves are depleted during the development of an oil deposit in an elastic-water-pressure mode, the water cut of the fluid gradually increases, reducing the efficiency of waterflooding and maintaining reservoir pressure by the system of injection wells. The rheological characteristics of th...

This study investigated the role of the geometrical parameters of a wedge block on its stability using physical and numerical modeling. For the purpose of physical modeling, a new experimental setup was developed, and the stability of rock slopes was modeled. Sensitivity analysis was performed on fo...

Introduction. A significant proportion of the fuel pump’s faults is associated with an electric motor (about 40%), the technical condition of which is determined by the value of the electrical resistance of the winding circuit. However, direct measurement of electrical resistance without removing th...

Recent advances in computational petrological modeling provide accurate methods for computing seismic velocities and density within the lithospheric and sub‐lithospheric mantle, given the bulk composition, temperature, and pressure within them. Here, we test an integrated geophysical‐petrological in...

The study was focused on the tectonic structure features of the Gulf of Aden, which includes three provinces. The western, central and eastern provinces differ in morphostructural segmentation of the spreading ridge of the Gulf of Aden, which took place in different geodynamic regimes of their forma...

The synthesis of realistic fog in images is critical for applications such as autonomous navigation, augmented reality, and visual effects. Traditional methods based on Koschmieder’s law or GAN-based image translation typically assume homogeneous fog distributions and rely on oversimplified scatteri...
