Abstract— Wavelet Package Threshold Algorithm (WPTA) is an effective tool for reducing noise from speech signals. Threshold method plays a key role inWPTA. Invariant threshold method, which is commonly used, can lead to severe loss of speech information because of unchanged thresholds. In this paper, three adaptive threshold methods are investigated: Time-Frequency (TF) Threshold; Teager Energy...

In the title compound, C(16)H(26)O(5)S, the oxathiol-ane ring adopts an envelope conformation, with the S atom 0.793 (3) Å out of the mean plane of the remaining four atoms. The cyclo-hexane ring of the menthol fragment adopts an almost ideal chair conformation, with all substituents in the equatorial positions. In the crystal, relatively strong, short and linear C-H⋯O hydrogen bonds link the m...

We show that whenever s > k(k + 1), then for any complex sequence (an)n∈Z, one has ∫ [0,1)k ∣∣∣∣ ∑ |n|6N ane(α1n+ . . .+ αkn ) ∣∣∣∣2s dα Ns−k(k+1)/2( ∑ |n|6N |an| )s . Bounds for the constant in the associated periodic Strichartz inequality from L to l of the conjectured order of magnitude follow, and likewise for the constant in the discrete Fourier restriction problem from l to L ′ , where s′...

Deflection profiles of y} and y are shown in Fig. 1 for M -100 kg, 7=490 kN, c = 307 m/sec, a = 226 m/sec, at t = 0.68, 1.02 ane 1.29 sec. At these times the mass positions are * = 52, 118, and 188 m. As shown in Fig. 1, maximum deflection is at the mass location. To determine the adequacy of the simplified mathematical model used in the analyses, the cable deflection at a known position was mo...
