A model is presented with the potential to account for all processes of the reactive Si – liquid interface including, e.g., current oscillations, and the formation of nano-, meso, and macropores with their specific dependence on crystal orientation. The model assumes that current flow is spatially and temporally inhomogeneous current thus flows in current(More)
We have analyzed first and second order multiresolution texture features in order to discriminate normal and pathological liver cell nuclei. Several combinations of first and second order texture features discriminate animals from the four different groups. The best feature pair (graylevel Variance of the euchromatine and Diagonal moment of the GLCM) gave a(More)
Germanium (Ge) nanowires have been produced by electrochemical etching of single-crystalline n-type Ge [100] in a HCl-containing aqueous electrolyte. Macropores could be etched at various etching currents after an optimized procedure for homogeneous pore nucleation was used. Because of the narrow band gap of Ge (0.66 eV), the leakage current through pore(More)
We propose and demonstrate a concept that mimics the magnetization of the heavy dust particles in a complex plasma while leaving the properties of the light species practically unaffected. It makes use of the frictional coupling between a complex plasma and the neutral gas, which allows us to transfer angular momentum from a rotating gas column to a(More)
The interaction forces between dust grains in a flowing plasma are strongly modified by the formation of ion wakes. Here, we study the interparticle forces mediated by ion wakes in the presence of a strong magnetic field parallel to the ion flow. For increasing magnetic flux densities a continuous decay of the interaction force is observed. This transition(More)
In this paper we provide a description of the LUHbots team. We describe the current state of the team as well as current plans and research goals towards the 2016 RoboCup@Work tournament in Leipzig. The software is based upon a ROS-architecture and the hardware uses a KUKA youBot as a basis. The focus of the team lies with failure tolerant approaches to(More)
