We present an intrinsically discrete-time characterization of wavelet coefficient decay. To be more precise, let f = (f(n))n∈Z be a sequence and denote by (dj,l)j≥1,l∈Z the coefficients obtained by passing f through a subsampled wavelet filter bank. Then it is common practice to relate the decay properties of (dj,l) to continuous-time smoothness spaces such as the homogeneous Besov spaces Ḃα p,...

The objective of this work was to evaluate the sensitivity of three different satellite signals (interferometric coherence (γ), backscattering coefficient (σ0) and NDVI) to corn biophysical parameters (leaf area index, height, biomass and water content) throughout its entire vegetation cycle. All of the satellite and in situ data were collected during the Multi-spectral Crop Monitoring (MCM’10)...

To use the VES-13 a tool for identifying vulnerable older people cultural adaptation was performed, a process that seeks the equivalence between the original instrument and its version in another culture. The evaluation of semantic, idiomatic, cultural and conceptual equivalence obtained a general average agreement of 78%, 78%, 97.0% and 94.0% respectively. Kappa coefficient was used to verify ...

Recently, the decision feedback channel estimation based on the minimum mean square error criterion (DF-MMSE-CE) using a fixed DF filter coefficient has been proposed to improve the channel estimation accuracy for DS-CDMA with frequency-domain equalization (FDE). In this paper, we propose adaptive DF (ADF)-MMSE-CE, in which the DF filter coefficient is adapted to changing channel conditions bas...

OBJECTIVE To verify the psychometric properties of the Cerebral Palsy: Quality of Life Questionnaire Children - child report (CPQol-Child) questionnaire, after it was translated and culturally adapted into Brazilian Portuguese. METHODS After the translation and cultural adaptation of the tool into Brazilian Portuguese, the questionnaire was answered by 65 children with cerebral palsy, aged 9-...

BACKGROUND The Health Service Quality Scale is a multidimensional hierarchical scale that is based on interdisciplinary approach. This instrument was specifically created for measuring health service quality based on marketing and health care concepts. The aim of this study was to translate and culturally adapt the Health Service Quality Scale into Brazilian Portuguese and to assess the validit...

An efficient adaptation technique of the delay is introduced for accomplishing more accurate adaptive linear equalization of nonminimum phase channels. It is focused that the filter structure and adaptation procedure of the adaptive Butler-Cantoni (ABC) equalizer is very suitable to deal with a variable delay for each iteration, compared with a classical adaptive linear transversal equalizer (L...

The Mouteh refractory pyrite concentrates at pulp densities of 1.5%, 3%, 4.5% and 6% were treated, using Thiobacillus ferrooxidans DSM 581 and the same bacteria adapted on the Mouteh pyritic concentrate. Compared with a non-adapted culture, use of an adapted inoculum of T. ferrooxidans increased bioleaching rate of iron by a factor of 1.940, 2.011, 1.859 and 1.559 for pulp densities 1.5%, 3%, 4...

BACKGROUND The SRS-22 is a valid instrument for the assessment of the health related quality of life of patients with Idiopathic scoliosis. The SRS-22 questionnaire was developed in USA and has been widely used in the English speaking countries. Recently it has been translated and validated in many other languages. The purpose of this study is to evaluate the reliability and validity of the ada...
