Spatial awareness in robotic swarms through local wireless communications

We propose a fully distributed approach to endow robots in a swarm with awareness of their relative position with respect to the rest of the swarm. Such spatial awareness can be used to support spatially differentiated task allocation or for pattern format ...

A fully distributed communication-based approach for spatial clustering in robotic swarms

In this work we propose a novel fully distributed approach to endow robots in a swarm with awareness of their relative position with respect to the rest of the swarm. Such spatial awareness can be used to support spatially differentiated task allocation or ...

Dewetting-driven hierarchical self-assembly of small semiconducting molecules

Roland Hany, Jakob Heier, Gian-Luca Bona, Raffaele Mezzenga

We describe the self-organization of PCBM and a cyanine dye on chemically patterned surfaces during spin coating from solution. On homogeneous surfaces, a transient bilayer forms, which in a later stage decomposes into PCBM droplets in a matrix of the cyan ...

Conductivity of SU-8 Thin Films through Atomic Force Microscopy Nano-Patterning

Nico de Rooij, Jürgen Brugger, Luis Guillermo Villanueva Torrijo, Cristina Martin Olmos, Peter Van der Wal

Processing fl exibility and good mechanical properties are the two major reasons for SU-8 extensive applicability in the micro-fabrication of devices. In order to expand its usability down to the nanoscale, conductivity of ultra-thin SU-8 layers as well as ...

Studies of the spatial variability of alpine snowfall using an X-band polarimetric radar

Michael Lehning, Alexis Berne, Danny Eddy Scipion Castillo

A mobile polarimetric X-band radar (MXPol) was deployed in Davos, Switzerland in collaboration with SLF (WSL - Institute for Snow and Avalanche Research). MXPol was installed in the beginning of October 2009 and collected valuable and continuous informatio ...

Fully Inkjet-Printed Parallel-Plate Capacitive Gas Sensors on Flexible Substrate

Nico de Rooij, Danick Briand, Francisco Molina Lopez

Small fully inkjet-printed gas sensors based on capacitive parallel-plate (PP) structures have been realized on flexible plastic foil and characterized. A gas sensing layer was inkjet-printed between inkjet-printed bottom and top silver electrodes. Compare ...

Computational approaches to developmental patterning

Andrew Charles Oates

Computational approaches are breaking new ground in understanding how embryos form. Here, we discuss recent studies that couple precise measurements in the embryo with appropriately matched modeling and computational methods to investigate classic embryoni ...

A fully adaptive numerical approximation for a two-dimensional epidemic model with nonlinear cross-diffusion

Ricardo Esteban Ruiz Baier

An epidemic model is formulated by a reaction–diffusion system where the spatial pattern formation is driven by cross-diffusion. The reaction terms describe the local dynamics of susceptible and infected species, whereas the diffusion terms account for the ...

Patterned growth of high aspect ratio silicon wire arrays at moderate temperature

Vasiliki Tileli

High aspect ratio silicon wire arrays with excellent pattern fidelity over wafer-scale area were grown by chemical vapor deposition at moderate temperature, using a gas mixture of silane and hydrogen chloride. An innovative two-step process was developed f ...

Quantitative Prediction Of Flow Patterns In Liquid-Liquid Flow In Micro-Capillaries

Lioubov Kiwi, Madhvanand Namadeo Kashid

Flow patterns in microstructured reactors (or microchannels) play an important role in dictating the mass transfer rates. In the present work, experiments were carried out to investigate the two phase (liquids) flow patterns in microchannels with different ...
