Wimax is a standard based wireless technology that provides high throughput broadband connection over long distance. It can offer low cost high speed and long range communications for applications. In wimax relay networks the relay stations are used to improve the transmission quality. Bandwidth allocation is the process of assigning bandwidth to users and applications. The comparative analysis...

Abstra t Most lassi ation algorithms experien e diÆ ulties when the input-output distribution is irregular (i.e., neighbor examples in the input spa e have di erent values in the output spa e), and sparse. We hara terize the diÆ ulty of a lassi ation problem using a limited number of examples by re-de ning a measure of lass variation to a ount for irregular distributions, and by introdu ing a n...

We consider a ferromagnetic Ising chain evolving under Kawasaki dynamics at zero temperature. We investigate the statistics of the metastable configurations in which the system gets blocked (statistics of energy, spin correlations, distribution of domain sizes). A systematic comparison is made with analytical predictions for the ensemble of all blocked configurations taken with equal a priori w...

We point out that polarization measurements such as the longitudinal fraction and the transverse left-right asymmetry in the Bauer-Stech-Wirbel (BSW) class III processes involving two final vector mesons, B → ρ−D∗ taken as an example, are useful in determining the relative sign as well as the relative magnitudes of the coefficients a1 and a2.

We exploit the identification between the critical theory of the 3-state Potts model and the D5 conformal model. This allows us to determine all 3-point correlations involving the fields associated with the Potts order parameter and the energy density. The calculation uses screened Coulomb gas correlations. The Z3 symmetry of the 3-state Potts model is manifestly preserved. ENSLAPP-L-526/95 Jun...

The analogue of the loop-loop correlation function in 2d gravity for the planar connected φ diagrams is calculated. It is shown that although the discretized formulas are different the scaling limit is the same as for the looploop correlation function. The derivation may serve as an alternative definition of the volume-volume correlator of Euclidean quantum gravity in 2d. LPTHE Orsay 96-13 Febr...
