On ∞ - Lie Urs
We discuss actions of Lie n-groups and the corresponding action Lie n-groupoids; discuss actions of Lie n-algebras (L∞-algebras) and the corresponding action Lie n-algebroids; and discuss the relation between the two by integration and differentiation. As an example of interest, we discuss the BRST complex that appears in quantum field theory. We describe it as the Chevalley-Eilenberg algebra o...

متن کاملParallélisation d'opérateurs de TI : multi-curs, Cell ou GPU ?
This article deals with a performance analysis of eight current architectures : general purpose multi-core processors, graphic processing units and the Cell processor. The benched algorithm is the Harris operator. The main goal is to guide the user in chosing a parallel architecture and to assess how different transformations impact so as to get an architecture optimised implementation.
متن کاملUreteroscopy (URS): an effective interventional and diagnostic modality.
OBJECTIVE To study the effectiveness and complications of the use of ureteroscope in the management of ureteral calculi and as diagnostic modality for ureteric strictures and hydroureter. PATIENTS AND METHOD URS was carried out in 125 consecutive patients. Technical failure to negotiate the ureteric orifice was observed in 10 (8%) patients. Three of them had passive dilatation with ureteric c...
متن کاملFraming pyramids
In 1983, Burt and Adelson introduced the Laplacian pyramid (LP) as a multiresolution representation for images. We study the LP using the frame theory, and this reveals that the usual reconstruction is suboptimal. We show that the LP with orthogonal filters is a tight frame, and thus, the optimal linear reconstruction using the dual frame operator has a simple structure that is symmetric with t...
