and Applied Analysis 3 The flow u(t) = S(t)g is a continuous semigroup of contractions in H−1(Ω) in this case or in L(Ω), in other situation, and the denoising effect of (6) is due to smoothing effect of S(t) on initial data, a property which is a characteristic to semigroups generated by the nonlinear operators A of the gradient type ∂φ, where φ is a convex and lower semicontinuous function. S...

This take a look at targets to investigate and study the impact of leverage, firm size, value, managerial ownership, institutional ownership audit committees on income smoothing. research was conducted Indonesian Stock Exchange manufacturing companies. The sampling method uses purposive with period from 2018 2021. relationship or influence between variables is explained using logical regression...

We are interested in this article in investigating the smoothing effect properties of the solutions of the Schrödinger equation. Since the work by Craig, Kapeller and Strausss [13], Kato [16], Constantin and Saut [12] establishing the smoothing property, many works have dealt with the understanding of this effect. In particular the work by Doi [14] and Burq [5, 6] shows that it is closely relat...

Surface properties of Hall-effect thruster channel walls play an important role in the performance and lifetime of the device. Physical models of near-wall effects are beginning to be incorporated into thruster simulations, and these models must account for evolution of channel surface properties due to thruster operation. Results from this study show differences in boron nitride channel surfac...

Co films ;970 Å thick were deposited, simultaneously, on ten plasma-etched Si~100! substrates with various etch times t . The surface morphologies and magnetic properties of the Co films were measured by atomic force microscopy ~AFM! and magneto-optic Kerr effect ~MOKE! technique. The analysis of the AFM images shows that as the etch time t increased from 0 to 100 min, the vertical interface wi...

We construct a potential V on R, smooth away from one pole, and a sequence of quasimodes for the operator −∆+V , which concentrate on this pole. No smoothing effect, Strichartz estimates nor dispersive inequalities hold for the corresponding Schrödinger equation.

In this paper we propose a method for spatio-temporal reconstruction of dynamic or gated image sequences. In a previous method we proposed, temporal smoothing in a Karhunen-Loève (KL) transform domain was used prior to reconstruction to reduce the effect of noise. Unlike the Bayesian priors that are usually used in image reconstruction, temporal KL smoothing is a data-driven approach that takes...

For a set of spatially dependent dynamical models, we propose a method for estimating parameters that control temporal dynamics by spatial smoothing. The new approach is particularly relevant for analyzing spatially distributed panels of short time series. The asymptotic results show that spatial smoothing will improve the estimation in the presence of nugget effect, even when the sample size i...
