seismic tomography is an imaging technique which creates maps of subsurface elastic properties such as p/s wave velocity, density and attenuation, based on observed seismograms and use of sophisticated inversion algorithms. amongst different acquisition geometries, seismic cross-hole tomography has a special position in geophysical surveys with many applications in hydrocarbons, coal and other ...

this paper presents an experimental study the influence of wave parameter on the damage of reshaping seawall, model tests have been performed in several water level conditions. the experiments of physical modeling of this research have been done in the flume of the soil conservation and watershed management research institute (scwmri). the waves applied to the structure model are irregular and ...

Millimeter-wave (mm-wave) radios have been gaining interest as one of the strong enabling physical layer technologies for the fifth-generation (5G) mobile and backhaul access. This paper aims at clarifying possible roles of the mm-wave radios in the 5G development and performing comprehensive literature survey on the radio channel modeling for the feasibility study of a radio link. Emphasis in ...

BACKGROUND We examine the effect of heat waves on mortality, over and above what would be predicted on the basis of temperature alone. METHODS Present modeling approaches may not fully capture extra effects relating to heat wave duration, possibly because the mechanisms of action and the population at risk are different under more extreme conditions. Modeling such extra effects can be achieve...

breaking waves have ability to transport large quantities of sediment and significant impact on coastal structures morphology. hence, modeling of wave breaking is an important subject in coastal and marine engineering. in this research, the periodic wave breaking process on a plane slope is studied experimentally and numerically. laboratory experiments were conducted to record water surface ele...

Block-based physical modeling is a methodology for modeling physical systems with different subsystems. Each subsystem may be modeled according to a different paradigm. Connecting systems of diverse nature in the discrete-time domain requires a unified interconnection strategy. Such a strategy is provided by the well-known wave digital principle, which had been introduced initially for the desi...

wave prediction is useful for safety and effective management of vessel navigation or construction of offshore structures. since human activity mainly takes place in nearshore regions, accurate wave prediction is necessary there. however, nearshore waves are not easy to predict compared with ocean waves, because not only the waves but also the wind, which is the energy source of the waves, chan...

Based on the recently introduced fractional Taylor’s formula, a fractional heat conduction constitutive equation is formulated by expanding the single-phase lag model using the fractional Taylor’s formula. Combining with the energy balance equation, the derived fractional heat conduction equation has been shown to be capable of modeling diffusion-to-Thermal wave behavior of heat propagation by ...
