This study aims to determine the utility of the narrative slope in predicting the vocational/productive outcomes of participants. For 65 participants living in supportive facilities for adults with HIV/AIDS in the United States, narrative slopes, based on the Occupational Performance History Interview II, were constructed and classified as progressive, stable, or regressive. Information regardi...

Flow velocity is one of the most important hydrodynamic variables for both channelized (rill and gullies) interrill erosive phenomena. The dye tracer technique to measure surface flow Vs based on measurement travel time a needed cover known distance. measured must be corrected obtain mean V using factor αv = V/Vs which generally empirically deduced. can influenced by method applied dye-tracer v...

Suspended solids or sediments can be pollutants in rivers, but they are also an important component of lotic food webs. Suspended sediment data for rivers were obtained from a United States-wide water quality database for 622 stations. Data for particulate nitrogen, suspended carbon, discharge, watershed area, land use, and population were also used. Stations were classified by United States En...

Primitive digraphs on n vertices, k arcs and girth s are considered. By a(n, k, s) we mean the minimum exponent taken over all such digraphs. We estimate the number a(n, k, s) using the Frobenius number for special values of k and s.

For stochastic growth models in the Kardar-Parisi-Zhang (KPZ) class in 1 + 1 dimensions, fluctuations grow as t1/3 during time t and the correlation length at a fixed time scales as t2/3. In this note we discuss the scale of time correlations. It turns out that the spacetime is non-trivially fibred, having slow directions with decorrelation exponent equal to 1 instead of the usual 2/3. These di...

X-ray and electron di!raction have been used to determine the surface roughness parameters of thin "lms and thus evaluate roughness e!ects on magnetic properties. For self-a$ne roughness, the demagnetizing factor is in#uenced by the roughness exponent H, and is proportional to w/m2 with w being the RMS roughness amplitude and m being the lateral correlation length. Roughness anisotropy can ampl...

Traditional time and frequency domain heart rate variability (HRV) have cardiac patients at risk of mortality post-myocardial infarction. More recently, non linear HRV has been applied to risk stratification of cardiac patients. In this review we describe studies of non linear HRV and outcome in cardiac patients. We have included studies that used the three most common non-linear indices: power...

An extension to the wavelet-based method for the estimation of the spectral exponent, γ, in a 1/ f γ process and in the presence of additive white noise is proposed. The approach is based on eliminating the effect of white noise by a simple difference operation constructed on the wavelet spectrum. The γ parameter is estimated as the slope of a linear function. It is shown by simulations that th...

We calculate the maximal Lyapunov exponent in constant-energy molecular dynamics simulations at the melting transition for finite clusters of 6 to 13 particles (model rare–gas and metallic systems) as well as for bulk rare– gas solid. For clusters, the Lyapunov exponent generally varies linearly with the total energy, but the slope changes sharply at the melting transition. In the bulk system, ...

Abstract In this paper, the outflow process of a linear width contraction device for free-flow condition is modeled using dimensional analysis and incomplete self-similarity condition. The proposed theoretical stage-discharge relationship tested measurements available in literature. power equation characterized by value exponent close to 2 coefficient depending on angle sides with channel bank....
