For a fairly general class of orthonormal scaling functions and wavelets with regularity exponents n, we prove that the areas of the timefrequency windows tend to infinity as n → ∞.


We study boundary value problems for the timeharmonic form of the Maxwell equations, as well as for other related systems of equations, on arbitrary Lipschitz domains in the threedimensional Euclidean space.

Finally, we consider the spline of order 2; we investigate numerically the region of the timefrequency plane where it generates a frame and we compute the dual function for some values of the parameters.


Our proofs proceed in the time domain and allow us to represent each solution regardless of the spectral radius of P(0):=2s∑cα, which has been a difficulty in previous investigations of this nature.


More generally, these results apply both to Gabor frames and to systems of Gabor molecules, whose elements share only a common envelope of concentration in the timefrequency plane.


The wellposedness for the timedependent neutron transport equation with integral boundary conditions is established inL1 space.


In a life test with 20 sets of bearings, only one set failed within the specified time, and none of the remainder failed even after the time of test has been extended.


It is shown that in this model the time delay can make a stable equilibrium become unstable and even a switching of stabilities.


The expressions for moments of the time to ruin with the model above are given.


It is shown that there is a simple approximation formula for the time of ruin when the level of dividend barrier is high and the claim sizes have a distribution that belongs to S(γ) with γ >amp;gt; 0.


The timeharmonic electromagnetic plane waves incident on a perfectly conducting obstacle in a homogeneous chiral environment are considered.


Moreover, this newly built system can reduce the time taken washing the sample cell from 30 min or so to about 10 min.


The discrete spectrum of the field after continuation is obtained from difference methods for Maxwell's curl equations in frequencydomain, and the time domain solution of the original problem is derived from their inverse Fourier transform.


Although the structure of frequency shift filter is more complicated than the timedomain filter, it uses both time correlations and frequency spectrum correlations so it can achieve better performances on separating the overlapping signals.


The time series stochastic process model of the Internet separation degree is established.


Only CDMA2000 1X EVDO or enhanced data rate for GSM evolution (EDGE), which adopts the Time Division Multiple Access (TDMA) mode, can provide the highspeed data rate for a wireless access.


In multiuser wireless communication systems, dynamic power allocation is an important means to deal with the timevarying nature of the physical and network layers.


Furthermore, we also discussed the best bases' choice for the timefrequency representation of HRIRs, and the results show that local cosine bases are more propitious to HRIRs' adaptive approximation than wavelet and wavelet packet base.


Since the relativity of visual evoked potentials from different sites should be stronger than those of the spontaneous electroencephalogram (EEG), this paper adopted the timelock averaged signals from multichannels as features.
