We investigate the mass profile of ΛCDM halos using a suite of numerical simulations spanning five decades in halo mass, from dwarf galaxies to rich galaxy clusters. These halos typically have a few million particles within the virial radius (r200), allowing robust mass profile estimates down to radii below 1% of r200. Our analysis confirms the proposal of Navarro, Frenk & White (NFW) that the ...

The history and theory supporting the idea of a universal log law for turbulent wall-bounded flows are briefly reviewed. The original idea of justifying a log law from a constant Reynolds stress layer argument is found to be deficient. By contrast, it is argued that the logarithmic friction law and velocity profiles derived from matching inner and outer profiles for a pipe or channel flow are w...

Thanks to the ever increasing computational power and the development of more sophisticated algorithms, numerical N -body simulations are now uncovering several phenomenological relations between the physical properties of dark matter haloes in position and velocity space. It is the aim of the present work to investigate in detail the dynamical structure of dark matter haloes, as well as its po...

A mathematical model is developed to study the MHD oscillatory blood flow through stenosed artery under the effect of slip velocity. The blood is assumed to be Newtonian. Analytical expressions for velocity profile, flow rate, wall shear stress and resistive impedance have been obtained. These expressions are computed numerically and the computational results are presented graphically. It is no...

in this paper, changes of casson non-newtonian fluid velocity profile, for different distribution of porosity, have been investigated. for distribution of porosity, fixed, radial and exponential variations has been considered. for all three states, brinkman model has been used as momentum equation. since the casson fluid is a good model for blood, this analysis can be used in studying about cho...

Abstract This paper considers the uncertainty in shear wave velocity (Vs) of soil and rock profiles for use earthquake site response calculations. is an important contributor to response, which turn ground motions seismic hazard. The begins with a discussion different types how they are characterized probabilistic hazard analysis, this differentiation particularly ambiguous case properties. fol...

The results of psychophysical studies suggest that displacement velocity may contribute significantly to the sensation of subcortical somatosensory neurons. The cortical correlates of these phenomena, however, are not known. In the present study the responses of rapidly adapting (RA) neurons in the forelimb region of cat primary somatosensory cortex (SI) to controlled displacement of skin and h...

A new view of the scaling of the streamwise turbulence intensity profile is proposed for the zero pressure gradient turbulent boundary layer. The method is based on the scale decomposed streamwise velocity component, separated into a smalland a large-scale contribution using a wavelength pass-filter. This enables us to understand how large and small scale motions affect the streamwise turbulenc...
