Coprosma kawaikiniensis K.R. Wood, Lorence & Kiehn (Rubiaceae), a rare endemic tree from Kaua'i, Hawaiian Islands, is described and illustrated along with a previously undescribed endemic plant community, the Dubautia-Sadleria shrubland-fernland (DSSF). The new species differs from Hawai'i congeners by its combination of opposite, long, elliptic to narrowly elliptic or ovate-elliptic leaves wit...

r SUMMARY The tests were made in the jft x jft tunnel to assess the performance of a rectangular twin-duct intake, including effeots of limited immersion of the intake xnto a wing boundary layer. The effects in one duct, arising from interference caused by varying the flow through the other, have slso been mvestigated. Partial immersion of the lntske into the wing boundary layer causes little d...

Numerical solutions presented in a companion paper show that two-dimensional mesoscale terrain becomes a much stronger barrier to a continuously stratified flow when the flow contains warm advection. Here it is shown that this baroclinic enhancement is a strictly nonlinear phenomenon. The linear analysis indicates a weakening of the upstream response in warm advection. However, a weakly nonline...

The modeling of atmospheric ice accretion on duplex cylinders received a limited attention, with carried by Wagner and Qing et al. publicly available experimental data about the is to experiments Veerakumar When comparing results al., major difference airflow behavior in wake windward cylinder, extent recirculation bubble, velocity distribution wake. Thus, its needed study effect turbulence mod...

We present measurements of wind velocity and sand flux performed on the windward side of a large barchan dune in Jericoacoara, northeastern Brazil. From the measured profile, we calculate the air shear stress using an analytical approximation and treat the problem of flow separation by an heuristic model. We find that the results from this approach agree well with our field data. Moreover, usin...

An engineering inviscid-boundary layer method has been modiied for application to slender three-dimensional (3-D) forebodies which are characteristic of transatmospheric vehicles. An improved shock description in the nose region has been added to the inviscid technique which allows the calculation of a wider range of body geometries. The modiied engineering method is applied to the perfect gas ...

Multispectral imaging (MSI) data acquired at different view angles provide an analyst with a unique view into shallow water. Observations from DigitalGlobe’s WorldView-2 (WV-2) sensor, acquired in 39 images in one orbital pass on 30 July 2011, are being analyzed to determine bathymetry along the windward side of the Oahu coastline. Satellite azimuth and elevation range from 18.8 to 185.8 degree...
