Abstract When testing the surface quality of finest structures, white‐light interferometers are in their element, both production and development, as well laboratories research. This measurement principle works on almost all materials, operates without contact, providing profiles 3D with height resolutions nanometer range. Today, large‐area measurements just possible detailed investigations hig...

A surface microtopography design and manufacturing methodology is presented that handles the intrinsic geometrical complexity of a surface microtopography by introducing topography descriptors. The concept of topography descriptor is a generalization originating from known techniques of three-dimensional surface topography analysis. Topography descriptors may be seen as transfer functions that ...

In this paper, we are concerned with models for sedimentation transport consisting of a shallow water system coupled with a so called Exner equation that described the evolution of the topography. We show that, for some model of the bedload transport rate including the well-known Meyer-Peter and Müller model, the system is hyperbolic and, thus, linearly stable, only under some constraint on the...

ÐThis paper investigates whether surface topography information extracted from intensity images using a recently reported shape-from-shading (SFS) algorithm can be used for the purposes of 3D object recognition. We consider how curvature and shape-index information delivered by this algorithm can be used to recognize objects based on their surface topography. We explore two contrasting object r...

Neuronal behaviour is profoundly influenced by extracellular stimuli in many developmental and regeneration processes. Understanding neuron responses and integration of environmental signals could impact the design of successful therapies for neurodegenerative diseases and nerve injuries. Here, we have investigated the influence of localized extracellular cues on polarization (i.e. axon formati...
