For nonautonomous and nonlinear differential difference equations depending on a parameter, we formulate sufficient conditions under which they exhibit Ck, k∈N shadowing with respect to parameter. Our results are applicable situations when the linear part is not hyperbolic. In case hyperbolic, obtain dealing parameterized Hyers-Ulam stability.

Partial shadowing has been identified as a main cause for reducing energy yield of grid-connected photovoltaic systems. The impact of the applied system configuration on the energy yield of partially shadowed arrays has been widely discussed. Nevertheless, there is still much confusion especially regarding the optimal grade of modularity for such systems. A 5-kWp photovoltaic system was install...

Let f be a diffeomorphism of a closed C∞ three-dimensional manifold. In this paper, we introduce the notion of C1-stably weak shadowing for a closed f -invariant set, and prove that C1-generically, for an aperiodic chain component Cf of f isolated in the chain recurrent set, if f|Cf is C 1-stably weak shadowing, then there are a C1-neighborhood U(f) of f and an open and dense subset V of U(f) s...

In this paper pseudoorbits of discrete dynamical systems are considered such that the one{step errors of the orbits tend to zero with increasing indices. First it is shown that close to hyperbolic sets such orbits are shadowed by true trajectories of the system with shadowing errors also tending to zero. Then the rates of convergence are studied via considering pseudoorbits such that the error ...

Nuclear shadowing corrections are dominated by soft interaction and grow as function of 1/x more slowly than the single scattering term, which has an essential contribution from hard interaction. Therefore we predict vanishing nuclear shadowing at very low x provided that Q is high and fixed. At the same time, at medium and low Q, nuclear shadowing grows with 1/x as is well known for soft hadro...

This study reports a shadowing experiment, in which one has to repeat a speech stimulus as fast as possible. We tested claims about a direct link between perception and production based on speech gestures, and obtained two types of counterevidence. First, shadowing is not slowed down by a gestural mismatch between stimulus and response. Second, phonetic detail is more likely to be imitated in a...

We study the effect of spatially homogeneous and inhomogeneous shadowing on J/psi production in deuterium-nucleus collisions. We discuss how the shadowing and its spatial dependence can be measured by comparing central and peripheral dA collisions. These event classes may be selected by using gray protons from heavy ion breakup and events where the proton or neutron in the deuterium does not in...

Propagation inside buildings suffer from large shadowing and high multipath effects. This is a serious problem for Wireless Local Area Network (WLAN) systems. OFDM has a high multipath tolerance and this paper shows how this can be used to overcome the problems due to shadowing. OFDM allows a base station to transmit and receive the same signal at the same frequency from multiple locations, at ...

We reexamine the predictions of a two-phase model of shadowing in nuclear deep-inelastic scattering in light of new NMC data on the x, A and Q 2 dependence of the ratios of structure functions. The model, which combines vector meson dominance at low Q 2 with diffractive Pomeron exchange for large Q 2 , agrees with the observed small, but non-zero, slopes in log Q 2 , which indicate the importan...
