An unbiased stereological estimator for surface area density is derived for gradient surface processes which form a particular class of non-stationary spatial surface processes. Vertical planar ...

Rapidly-varying free-surface flows are characterized by large surface gradients. These flows can be found for example, in hydraulic jumps, tsunamis, tidal bores and releases from power stations. Large ...

Researchers from the National Institute of Standards and Technology (NIST) have demonstrated an elegantly simple technique for synthesizing a wide variety of complex surfaces that vary in a controlled ...

In order to push the performance of optical systems, aspheric- and freeform surfaces are used in state-of-the-art optic design for correcting aberrations. The production of these complex-shaped ...

In high-gradient channels the sediment which is present on the bed surface (the armor layer) is typically much coarser than the sediment which moves as bed load during high-flow events. The difference ...
