Portfolio management starts with asset allocation. There is a consensus that asset allocation plays an important role in determining portfolio performance (Arshanapalli, Coggin & Nelson, 2001). Active portfolio management implies the rebalancing of the existing portfolio by buying and selling assets. The aim of rebalancing is to improve the performance of the managed portfolio by adjusting it t...

Location of the internship: The internship will be jointly between the WILLOW team at INRIA Paris1 and the LEAR team at INRIAGrenoble2, and will be co-supervised by Jean Ponce and Cordelia Schmid, a ENS professor and a INRIA research director respectively. Both teams are specialized in computer vision, in particular visual recognition. Armand Joulin, a researcher at FaceBook, will be an externa...

Asteroid 3200 Phaethon resembles a comet in some ways, including a highly-eccentric orbit (e∼ 0.89) and a strong associated meteor shower (the Geminids). Yet this object has never been observed to exhibit any cometary activity, i.e., gas production. We observed 3200 Phaethon with the Caltech Submillimeter Observatory on two occasions, once while it was near its closest approach to Earth as it n...

Aromatic aldehydes are efficiently condensed with 2'-hydroxyacetophenone by polymer-supported basic ionic liquid as an excellent heterogeneous catalyst utilizing the Claisen–Schmidt reaction. Microwave irradiation has been employed, providing flavanone in good yield and short reaction time.

We prove the following statements about bounded linear operators on a separable, complex Hilbert space: (1) Every normal operator N that is similar to a Hilbert-Schmidt perturbation of a diagonal operator D is unitarily equivalent to a Hilbert-Schmidt perturbation of D; (2) For every normal operator A', diagonal operator D and bounded operator X, the Hilbert-Schmidt norms (finite or infinite) o...

In this work, an efficient way to predict the dynamics of a scalar at high Schmidt numbers, advected by a turbulent flow, is presented. For high Schmidt numbers, the spatial resolution required for the scalar field has to be finer than the resolution required for the velocity field, leading to a significant computational cost due to the CourantFriedrichs-Lewy (CFL) constraint. We propose here a...

The Stokes-Einstein relation for the self-diffusion coefficient of a spherical particle suspended in an incompressible fluid is an asymptotic result in the limit of large Schmidt number, that is, when momentum diffuses much faster than the particle. When the Schmidt number is moderate, which happens in most particle methods for hydrodynamics, deviations from the Stokes-Einstein prediction are e...

This report describes the state of the research and practice in the areas of metadata management systems. Open source and industrial products are presented and compared. Thereout we identified functional and non-functional requirements relevant for the TEAM project. Project co-funded by the European Commission under the “Information Society Technology” Programme, Framework Programme 6. D5: Repo...
