Standard face recognition algorithms that use standard feature extraction techniques always suffer from image performance degradation. Recently, singular value decomposition and low-rank matrix are applied in many applications,including pattern recognition and feature extraction. The main objective of this research is to design an efficient face recognition approach by combining many tech...

  In this paper, we propose a nonparametric rank-based alternative to the least-squares independent component analysis algorithm developed. The basic idea is to estimate the squared-loss mutual information, which used as the objective function of the algorithm, based on its copula density version. Therefore, no marginal densities have to be estimated. We provide empirical evaluation of th...

BACKGROUND Since 1958 many, but not all studies have demonstrated that paternal age is a risk factor for schizophrenia. There may be many different explanations for differences between studies, including study design, sample size, collection criteria, heterogeneity and the confounding effects of environmental factors that can for example perturb epigenetic programming and lead to an increase in...

Interactive media is something that important to be developed in order improve students' mathematical understanding abilities. One of the learning used scratch. Scratch-assisted on rank numbers material made make it easier for students understand concepts and increase student interest learning, by studying expected able give birth creative making based scratch animation. The research design thi...

Colostrum intake from birth to 24 h after the onset of parturition (T24) was estimated for 526 piglets from 40 litters. Plasma concentrations of immunoglobulin G (IgG), lactate, glucose and cortisol were determined at T24 for six piglets per litter. Plasma IgG concentration was also assayed at weaning (28 days) on the same piglets. Rectal temperature was measured at T24 on all piglets. Mortalit...

accidents are one of the mortality reasons and most important agents of disability in primary school children. in this research, educational needs of 10-12 years old children who studied in fourth and fifth class in governmental primary schools of tehran city about accident prevention are assessed by questionnaire. results showed that majority of children had correct performance and had low edu...
