Turbulent velocity, temperature, water vapor concentration, and other scalars were measured at the canopy– atmosphere interface of a 13–14-m-tall uniform pine forest and a 33-m-tall nonuniform hardwood forest. These measurements were used to investigate whether the mixing layer (ML) analogy of Raupach et al. predicts eddy sizes and flow characteristics responsible for much of the turbulent stre...

An attenuation-based method to retrieve vertical profiles of rainfall rate from vertically pointing Ka-band radar measurements has been refined and adjusted for use with the U.S. Department of Energy’s cloud radars deployed at multiple Atmospheric Radiation Program (ARM) test bed sites. This method takes advantage of the linear relationship between the rainfall rate and the attenuation coeffici...

Multi-barreled composite foundations are generally used in offshore oil platform structure. However, there is still a lack of theoretical analyses and experimental research. This paper presents the results three-dimensional finite element analysis four-barreled suction pile foundation heterogeneous clay foundation.

The H component of geomagnetic field shows a daytime maximum in low iatitudes. It is explained as due to two circular(Sq)current systems in the ionospheric E region, with foci at about 30° latitude, one in each hemisphere, Northern and Southern. At the dip equator, the two current systems accentuate each other. In addition, the vertical Hall currents are greatly inhibited causing alarge, vertic...

Concepts of non-volatile memory to replace conventional flash memory have suffered from low material reliability and high off-state current, and the use of a thick, rigid blocking oxide layer in flash memory further restricts vertical scale-up. Here, we report a two-terminal floating gate memory, tunnelling random access memory fabricated by a monolayer MoS2/h-BN/monolayer graphene vertical sta...

The stability of a railway bridge is mainly governed by level of acceleration, vertical displacement, and twist. While acquiring acceleration is relatively easy task in the data measurement respective, displacement and twist are very challenging due to lack of appropriate sensors. Furthermore, as most existing displacement sensors are confined to measuring single displacement, twist which is ob...

We present a spectral linear analysis in terms of advected Fourier modes to describe the behavior of a fluid submitted to four constraints: shear (with rate S), rotation (with angular velocity Ω), stratification, and magnetic field within the linear spectral theory or the shearing box model in astrophysics. As a consequence of the fact that the base flow must be a solution of the Euler-Boussine...

Consider a nearest neighbor random walk on the two-dimensional integer lattice, where each vertex is initially labeled either `H' or `V', uniformly and independently. At discrete time step, walker resamples label at its current location (changing to `V' with probability $q$). Then, it takes mean zero horizontal step if new `H', vertical `V'. This model randomized version of deterministic rotor ...
