Daily Routine Classification from Mobile Phone Data

The automatic analysis of real-life, long-term behavior and dynamics of individuals and groups from mobile sensor data constitutes an emerging and challenging domain. We present a framework to classify people's daily routines (defined by day type, and by g ...

STMBench7: A Benchmark for Software Transactional Memory

Rachid Guerraoui, Michal Kapalka

Software transactional memory (STM) is a promising technique for controlling concurrency in modern multi-processor architectures. STM aims to be more scalable than coarse-grained locking and easier to use than fine-grained locks. However, STM implementatio ...

Chemical nanopatterns via Nanoimprint Lithography for simultaneous control over azimuthal and polar alignment of liquid crystals

Toralf Scharf

The use of chemical nanopatterns through nanoimprint lithography ato align a nematic liquid crystal (LC) in LC cells was described. It was found that the ratio of areas with different surface-aligning helped in the polar orientation of LC, while the azimut ...

Bioresorbable composites prepared by supercritical fluid foaming

Dominique Pioletti, Pierre-Etienne Bourban

Bone is a natural composite construct, with a gradient structure going from a loose interconnected cellular core to an outer dense wall, thus minimizing bone weight while keeping a high mechanical resistance. Due to this unique and complex structure, bone ...

Structuration of micro-fluidic devices based on low temperature co-fired ceramic (LTCC) technology

Peter Ryser, Thomas Maeder, Caroline Jacq, Hansu Birol, Yannick Sébastien Fournier, Giancarlo Corradini, Sigfrid Straessler

Smart packaging concept has been the driving force for the search of advanced technologies to produce multi-functional micro-scale devices for long years. In this sense, LTCC technology has been recently addressed as the suitable choice for a wide range of ...

Fluorine in an heteroaromatic context

Thierry Rausis

The organometallic approach to the functionalization of arenes and heteroarenes has recently been investigated by our group introducing modifications of the standard methods. This includes, in particular, the basicity-driven heavy halogen migration, which ...

Structure and mechanism of the alkyl hydroperoxidase AhpC, a key element of the Mycobacterium tuberculosis defense system against oxidative stress

Stewart Cole

The peroxiredoxin AhpC from Mycobacterium tuberculosis (MtAhpC) is the foremost element of a NADH-dependent peroxidase and peroxynitrite reductase system, where it directly reduces peroxides and peroxynitrite and is in turn reduced by AhpD and other protei ...

Normalization and correlation of cross-nested logit models

Michel Bierlaire, Emmanuel Abbé

Demand analysis is more and more critical in the transportation context. Discrete choice models methodology provide an appropriate framework to capture the behaviour of the actors of transportation systems and, consequently, to forecast the demand. Recentl ...

Optical emission spectroscopy of electrical discharge machining plasma

Christoph Hollenstein, Antoine Descoeudres

Plasma created during electrical discharge machining is systematically investigated using optical emission spectroscopy. Typical spectra show a strong H-alpha and continuum radiation, with many lines emitted by impurities coming from electrode and workpiec ...

Investigation of the basic properties of phase singularities generated by a phase bar or trench

Hans Peter Herzig

In the present paper, we determine the conditions necessary for the generation of phase singularities in the far-field by a phase bar or a trench. The ultimate goal of our work is to link object parameters to a topological distribution of pairs of singular ...
