Robust numerical integration on curved polyhedra based on folded decompositions

Annalisa Buffa, Pablo Antolin Sanchez, Xiaodong Wei

We present a novel method to perform numerical integration over curved polyhedra enclosed by high-order parametric surfaces. Such a polyhedron is first decomposed into a set of triangular and/or rectangular pyramids, whose certain faces correspond to the g ...

A 3D printed bio-composite removable connection system for bamboo spatial structures

Anastasios Vassilopoulos, Romain Pascal T van Wassenhove

A 3D printed bio-composite removable connection system for bamboo space structures is introduced in this paper. The system consists of a removable clipping connection for raw bamboo structures, adapted to the European market. The use of parametric design a ...

Analysis of double cross-slip of pyramidal I < c plus a > screw dislocations and implications for ductility in Mg alloys

William Curtin, Zhaoxuan Wu, Rasool Ahmad

Solute accelerated cross-slip of pyramidal < c + a > screw dislocations has recently been recognized as a crucial mechanism in enhancing the ductility of solid-solution Mg alloys. In pure Mg, cross-slip is ineffective owing to the energy difference between ...

First-principles calculations of stacking fault energies in Mg-Y, Mg-Al and Mg-Zn alloys and implications for < c plus a > activity

William Curtin, Binglun Yin, Zhaoxuan Wu

Mg-3wt.%RE alloys show substantially enhanced < c + a > activity as compared to pure Mg or other Mg-Al, Mg-Zn alloys of similar grain sizes. Activation of < c + a > slip has been postulated to be associated with the reduction of the basal Li stacking fault ...

Morphological development of thick-tufted layer v pyramidal cells in the rat somatosensory cortex

Henry Markram, Yun Wang, Sandrine Romand

The thick-tufted layer V pyramidal (TTL5) neuron is a key neuron providing output from the neocortex. Although it has been extensively studied, principles governing its dendritic and axonal arborization during development are still not fully quantified. Us ...

Growth model of MOCVD polycrystalline ZnO

Christophe Ballif, Sylvain Nicolay, Sylvie Faÿ

A growth model for the low pressure chemical vapor deposition (LPCVD) of polycrystalline ZnO thin films is proposed. This model is based on experimental observations of the surface morphology and crystallographic orientations of the layers at different thi ...

Contact compression of self-assembled nano- and micro-scale pyramid structures on Au (100) surface

Jian Wang, William Curtin

A process of self-assembly induced by electro-chemical etching was used to produce nano and micrometer scale pyramid-structures on (100) surfaces of gold. The pyramids grew in a self-similar fashion with the facets aligned in (114) plane. Using the unique ...

Microelectrodes with three-dimensional structures for improved neural interfacing

Philippe Renaud, Marc Olivier Heuschkel, Stefan Metz, Raphael Holzer

This paper describes the development of microelectrodes with integrated three-dimensional electrode structures. The integration of three-dimensional structures aims at an improvement of the electrode/tissue interface. Due to the increase in surface area th ...
