background: family-centered care is an essential concept in cancer but there is no consensus about its meaning and it remains an abstract concept. this study was conducted with the purpose of analyzing the concept of family-centered care in cancer. methods: concept analysis of family-centered care was conducted using hybrid model that has 3 phases: theoretical, field work and final analytical p...

the increasing reliance on information gathered from the web and other internet technologies raise the issue of trust. through the development of semantic web, one major difficulty is that, by its very nature, the semantic web is a large, uncensored system to which anyone may contribute. this raises the question of how much credence to give each resource. each user knows the trustworthiness of ...

Hydrological time series forecasting remains a difficult task due to its complicated nonlinear, non-stationary and multi-scale characteristics. To solve this difficulty and improve the prediction accuracy, a novel four-stage hybrid model is proposed for hydrological time series forecasting based on the principle of 'denoising, decomposition and ensemble'. The proposed model has four stages, i.e...

In this paper, we present a hybrid particle swarm optimization and support vector regression approach to predict exchange rate. This hybrid method examines the validity to optimize the parameters of penalty term and kernel function. For the experiments, the data of exchange rates (USD/CNY, EUR/CNY and CNY/JPY) are examined and optimized to be used for time series predictions with hybrid particl...

Accurate and reliable forecasts of diarrhea incidences are necessary for the health authorities to ensure the appropriate action for the control of the outbreak. In this paper, a novel hybrid model known as EEMD-GRNN is proposed to forecast the diarrhea incidences. The proposed approach first uses Ensemble Empirical Mode Decomposition (EEMD), which can adaptively decompose the complicated raw t...

a parallel hybrid system of hmm and gmm modeling techniques was implemented and used in a telephony speaker verification and identification system. spectral subtraction and weighted projection measure were used to render this system more robust against additional noise. cepstral mean subtraction method was also applied for the compensation of convolution noise due to transmission channel degrad...
