We summarize several limit results for the profile of random plane-oriented recursive trees. These include the limit distribution of the normalized profile, asymptotic bimodality of the variance, asymptotic approximations of the expected width and the correlation coefficients of two level sizes. We also unveil an unexpected connection between the profile of plane-oriented recursive trees (with ...

Relationship between displacement and velocity amplitudes of seismic waves was examined with data at stations within 200 km from 142 local earthquakes in and near Japan. The expected value of the coefficient for the logarithmic velocity amplitude to the logarithmic displacement amplitude is 0.5 when a self-similar scaling model is assumed. Observed value of the coefficient is about 0.8∼0.9. Thi...

The interaction between a turbulent boundary layer flow and compliant surfaces is investigated experimentally. Three viscoelastic coatings with different material stiffnesses are used to identify the general surface response conditions. For softest coating, global force measurements show two obvious regimes of an indicated transition at $U_b/C_t\sim 3.5$ , where $U_b$ bulk velocity $C_t$ coatin...

The streamwise velocity statistics in fully-developed rough-wall channel flow have been investigated over gritand mesh-type surface topologies. The flow was demonstrated to be fully-developed and two-dimensional up to the fourth moment of velocity. Though the flow over both surface types appear to exhibit a limited logarithmic region, the regions of inner and outer scaling over the mesh surface...

This paper describes an electromagnetic flow meter for velocity profile measurement in single phase and multiphase flows with non-uniform axial velocity profiles. A Helmholtz coil is used to produce a near-uniform magnetic field orthogonal to both the flow direction and the plane of an electrode array mounted on the internal surface of a non-conducting pipe wall. Induced voltages acquired from ...

We study the statistics of passive scalars at $Pr=1$ , for turbulent flow within a smooth straight pipe circular cross section up to $Re_{\tau } \approx 6000$ using direct numerical simulation (DNS) Navier–Stokes equations. While featuring general organisation similar axial velocity field, scalar fields show additional energy small wavenumbers, resulting in higher degree mixing and $k^{-4/3}$ s...

The numerical simulation of a Poiseuille flow in a narrow channel using the molecular dynamics simulation (MDS) is performed. Poiseuille flow of liquid Argon in a nanochannel is simulated by embedding the fluid particles in a uniform force field. Density, velocity and Temperature profiles across the channel are investigated. When particles will be inserted into the flow, it is expected that the...

We present a detailed analysis of the baryonic and dark matter distribution in the lensing cluster Abell 611 (z=0.288), with the goal of determining the dark matter profile over an unprecedented range of cluster-centric distance. By combining three complementary probes of the mass distribution, weak lensing from multi-color Subaru imaging, strong lensing constraints based on the identification ...
