Thoracic vibrations in stingless bees (Melipona seminigra): resonances of the thorax influence vibrations associated wit...
Bees generate thoracic vibrations with their indirect flight muscles in various behavioural contexts. The main frequency component of non-flight vibrations, during which the wings are usually folded over the abdomen, is higher than that of thoracic vibrations that drive the wing movements for flight. So far, this has been concluded from an increase...

Unusual Electric Burns Caused by Communication Disc Contact with a High-voltage Electric Transmission Cable: a Potential...
Published in Annals of burns and fire disasters
The case reported is that of a communications technician admitted to hospital with 38% burns sustained while climbing a communications mast. The mast was erected less than 3 metres from a 33 kv electric transmission cable. His condition is described, as also the treatment he received until his discharge three months later. In the absence of guideli...

Nonnegative tensor factorization for continuous EEG classification
In this paper we present a method for continuous EEG classification, where we employ nonnegative tensor factorization (NTF) to determine discriminative spectral features and use the Viterbi algorithm to continuously classify multiple mental tasks. This is an extension of our previous work on the use of nonnegative matrix factorization (NMF) for EEG...
Les réseaux formels et informels d'une organisation, l'ADBS, perspective et enjeux de la communication
La problématique du réseau permet de croiser les champs du management, de la communication, mais aussi des sciences humaines. Ce travail s'intéresse à la stratégie de la communication dans une association professionnelle de documentalistes, l'ADBS. Il tente d'en considérer les interactions et les enjeux sur l'exercice du pouvoir. Après une présenta...
MULTILAYER EFFECTS ON MICROSTRIP ANTENNAS FOR THEIR INTEGRATION WITH MECHANICAL STRUCTURES
The effect of multilayer geometry on microstrip antennas is investigated for the design of antenna-integrated mechanical structure. Changes in the gain of antenna due to the geometry have been determined using a transmission line analogy. Design of high-gain antenna in bandwidth is proposed away from structural resonance. Experiments are done on mi...
Synthesis and stacked conformations of symmetrical and unsymmetrical oligo-ureas of metaphenylenediamine.
Published in The Journal of organic chemistry
The addition of substituted anilines to nitro-substituted isocyanates followed by reduction generates new aniline-substituted ureas, which can be further extended in a one- or two-directional iterative manner to form oligomeric ureas based on a m-phenylenediamine monomer. Oligo-ureas with up to eight urea linkages are reported. Fully N-substituted ...
A Methodology and Measure of Performance for the Evaluation of Commuters Information Systems
The objective of this paper is to prove the effectiveness of variable message sign information on recurrent congestion using different measurements of effectiveness. To show the benefits of the information systems, we have built a new methodology. We took advantage of the data collected during a national strike which shut down the variable message ...
