in this study, the feasibility of using magnetic technology to reduce the dispersion of soil has been investigated. the reference treatment was potable water and 3 magnetic water devices (with different magnetic intensities) were used for magnetizing the potable water. the results showed that the magnetic field has a significant effect in order of 5 percent on increasing of magnesium concentrat...

Conventional Time-Frequency and Time-Scale Representations are often too rigid to capture fine details of sound or musical signals. Adaptation of ideal time-frequency tilings is often desirable in order to represent the signal in terms of components that are meaningful from a physical or perceptual point of view. Remapping of the time and frequency axes by means of time and frequency warping ca...

dispersive soils are prevailent in many parts of the world, including in iran. construction of hydraulic structures on dispersive soils has created various serious problems. since it is neither economical nor justified to replace a dispersive soil with a non-dispersive one, there fore stabilization of a dispersive soil in one way or another is indispensable and unavoidable. throughout this rese...

Dispersive shock waves and solitons are fundamental nonlinear excitations in dispersive media, but dispersive shock wave studies to date have been severely constrained. Here, we report on a novel dispersive hydrodynamic test bed: the effectively frictionless dynamics of interfacial waves between two high viscosity contrast, miscible, low Reynolds number Stokes fluids. This scenario is realized ...

Heat transfer enhancements are investigated inside channels by controlling thermal dispersion effects inside the fluid. Different distributions for the dispersive elements such as nanoparticles or flexible hairy fins extending from the channel plates are considered. Energy equations for different fluid regions are dimensionalized and solved analytically and numerically. The boundary arrangement...

For a typical NRZ pulse propagating in existing normally dispersive bers, we provide a uniform description of the optical transmission. There are three distinct regimes of the governing nonlinear Schrr odinger equation: the fully nonlinear dispersive regime (ND), which covers a small region of the pulse; and two limiting asymptotic regimes-nonlinear, weakly dispersive (ZD) (for the bulk of the ...

We show that a collection of two-level atoms in an optical cavity beyond the rotating wave approximation and in the dispersive-adiabatic and non-dispersive adiabatic regime constitutes a nonlinear medium and is capable of generating squeezed state of light. It is found that squeezing produced in the non-dispersive adiabatic regime is significantly high compared to that produced in the dispersiv...
