Singularity Detection And Processing With Wavelets
 IEEE Transactions on Information Theory
, 1992
"... Most of a signal information is often found in irregular structures and transient phenomena. We review the mathematical characterization of singularities with Lipschitz exponents. The main theorems that estimate local Lipschitz exponents of functions, from the evolution across scales of their wavele ..."

of their wavelet transform are explained. We then prove that the local maxima of a wavelet transform detect the location of irregular structures and provide numerical procedures to compute their Lipschitz exponents. The wavelet transform of singularities with fast oscillations have a different behavior that we
Loopy belief propagation for approximate inference: An empirical study. In:
 Proceedings of Uncertainty in AI,
, 1999
"... Abstract Recently, researchers have demonstrated that "loopy belief propagation" the use of Pearl's polytree algorithm in a Bayesian network with loops can perform well in the context of errorcorrecting codes. The most dramatic instance of this is the near Shannonlimit performanc ..."

preliminary results investigating the cause of the oscillations and showed that it is not sim ply a matter of the size of the network or the number of parents. Rather the same structure with different parameter values may oscillate or exhibit stable be havior. For all our simulations, we found that when loopy
Consensus and cooperation in networked multiagent systems
 Proceedings of the IEEE
, 2007
"... Summary. This paper provides a theoretical framework for analysis of consensus algorithms for multiagent networked systems with an emphasis on the role of directed information flow, robustness to changes in network topology due to link/node failures, timedelays, and performance guarantees. An ove ..."

Pricing with a Smile
 Risk Magazine
, 1994
"... prices as a function of volatility. If an option price is given by the market we can invert this relationship to get the implied volatility. If the model were perfect, this implied value would be the same for all option market prices, but reality shows this is not the case. Implied Black–Scholes vol ..."

that the Nikkei oscillates with a constant volatility of 20 % for six months but also oscillates with a constant volatility of 18 % for one year. It is easy to solve this paradox by allowing volatility to be timedependent, as Merton did (see Merton, 1973). The Nikkei would first exhibit an instantaneous
Time varying structural vector autoregressions and monetary policy
 REVIEW OF ECONOMIC STUDIES
, 2005
"... Monetary policy and the private sector behavior of the US economy are modeled as a time varying structural vector autoregression, where the sources of time variation are both the coefficients and the variance covariance matrix of the innovations. The paper develops a new, simple modeling strategy f ..."

Correlation between spin structure oscillations and domain wall velocities
"... Magnetic sensing and logic devices based on the motion of magnetic domain walls rely on the precise and deterministic control of the position and the velocity of individual magnetic domain walls in curved nanowires. Varying domain wall velocities have been predicted to result from intrinsic effects ..."

such as oscillating domain wall spin structure transformations and extrinsic pinning due to imperfections. Here we use direct dynamic imaging of the nanoscale spin structure that allows us for the first time to directly check these predictions. We find a new regime of oscillating domain wall motion even below
Structures, Oscillations and Solitons in LargeScale Multicomponent SelfGravitating Systems

We consider two cases, galaxy clusters and cosmic walls, for illustrations. In both cases stability analyses are conducted using perturbative expansion. We have foun ..."

Atomic data from the Iron Project XXXV. Relativistic ne structure oscillator strengths for Fe XXIV and Fe XXV
, 1998
"... Abstract. The rst largescale calculations of relativistic radiative transition probabilities from the Iron Project is reported for dipole allowed and intercombination (E1) transitions in Lilike Fe XXIV and Helike Fe XXV. The ab intio calculations are carried out in the close coupling approximatio ..."

combination ne structure transitions involving the calculated bound levels up to n = 10 and ‘ = 5 or 6 are considered. Oscillator strengths, line strengths, and Einstein Acoecients are tabulated for 802 transitions in Fe XXIV and 2579 transitions in Fe XXV. The results compare well with limited subsets
A Study of Active Queue Management for Congestion Control

We first study the current proposals for RED implementation and identify several structural problems such as producing large traffic oscillations and introducing unnece ..."
