Under suitable ergodicity assumptions on the underlying difusion, we show existence of these asymptotics, and that they solve the related HJB equation in the viscosity sense.

This paper proposes play as another possible perspective. Everyday uses of the computer increasingly show signs of similarity to play. This is not discussed with regard to the so-called media society, the playful society, the growing cultural acceptance of the computer, the spread of computer games or a new version of Windows, but in view of the playful character of interaction with the computer that has always been part of it. The exploratory learning process involved with new software and the creative tasks that are often undertaken when using the computer may support this argument. Together with its high level of interactivity, these observations point to a sense of security, autonomy and freedom of the user that produce play and are, in turn, produced by play. This notion of play refers not to the playing of computer games, but to an implicit, abstract (or symbolic) process based on a certain attitude, the play spirit. This attitude is discussed regarding everyday computer use and related to the other mentioned perspectives.

The unprecedented expansion of the higher education sector and the increasing autonomy conferred to universities have created a huge demand for competent university leadership that supports the development of higher education in Malaysia.

While WR 2 shows no variability above the noise level, the other stars do show variation, which are like other WR stars in WR 152 but very fast in WR 3. From these motions, we deduce a value of β ∼1 for WR 3 that is like that seen in O stars and β ∼2–3 for WR 152, that is intermediate between other WR stars and WR 3.

T1 - Improving distances to Galactic Wolf-Rayet stars JF - Wolf-Rayet Stars : Proceedings of an International Workshop held in Potsdam, Germany, 1.–5. June 2015 N2 - Before GAIA improves the HIPPARCOS survey, direct determination of the distance via parallax is only possible for γ Vel, but the analysis of the cluster or association to which WR stars are associated can give distances with a 50% to a 10% accuracy. The list of Galactic clusters, associations and clusters/association candidates has grown significantly in the last decade with the numerous deep, high resolution surveys of the Milky Way. In this work, we revisit the fundamental parameters of known clusters with WR stars, and we present the search for new ones. All our work is based on the catalogs from the VVV (from the VISTA telescope) and the UKIDS (from the UKIRT telescope) near infrared surveys. Finally, the relations between the fundamental parameters of clusters with WR stars are explored.

June 2015 N2 - Carbon-rich Wolf-Rayet stars are efficient carbon dust makers. Despite the strong evidence for dust formation in these objects provided by infrared thermal emission from dust, the routes to nucleation and condensation and the physical conditions required for dust production are still poorly understood. We discuss here the potential routes to carbon dust and the possible locations conducive to dust formation in the colliding winds of WC binaries.
