... exists m ≥ 0 such that β(t) ≥ ϕ ∗ for all t ∈ I − and β  (t) = m ≥ max y ≤max I β f(t, β(t), y) for a.a. t ∈ I 0 . Therefore, α and β are lower and upper solutions for problem (1).  Example 5 ... that β (t) ≥ k(t) for all t ∈ I − and β  (t) = m ≥ max y ≤max I β(t) f(y) for all t ∈ I 0 . (25) So we deduce from (24) and (25) that α and β are lower and upper solutions...

Dyadic decomposition divides the input signal bandwidth into the logarithmic set of bandwidths, whereas the uniform decomposition divides it into the uniform set of bandwidths. ... frequency subbands of the frame. Each frame of speech signal is decomposed (uniformly/dyadic) into different frequency subbands using discrete wavelet transform (DWT) and each subband...
