Single sample face identification utilizing sparse discriminative multi manifold embedding

This paper describes three methods to improve single sample dataset face identification. The recent approaches to address this issue use intensity and do not guarantee for the high accuracy under uncontrolled conditions. This research presents an approach based on Sparse Discriminative Multi Manifold Embedding (SDMME) , which uses feature extraction rather than intensity and normalization for pre–processing to reduce the effects of uncontrolled condition such as illumination. In average this study improves identification accuracy about 17% compare to current method

Effects of Maternal Coagulation disorder on Birth Weight and Post-Natal Non-Coagulation Problems of Neonates

Background: To evaluate the birth weight and post-natal non-coagulation problems of infants of mothers with coagulopathies versus normal mothers. Materials and Methods: In a retrospective cohort study, 100 women with coagulation problems attended the Iranian Haemophilia Comprehensive Care Center, and 200 normal women attending two health centers in Tehran and Karaj, with a history of at least one pregnancy were studied. A questionnaire about mothers’ and neonates’ condition was filled out by an interview, and the data were analyzed using SPSS software, version 16. Results: Using linear regression, the maternal coagulation problem had a negative effect on birth weight (p<0.001, β= -0.31). The prevalence of early and prolonged jaundice in newborns of mothers with coagulopathy was higher than that in newborns of normal mothers (12% vs. 2%, and 7% vs. 3%, respectively), the difference between the two groups in terms of incidence of early jaundice was statistically significant (chi square-p<0.001). The frequency of using phototherapy and blood exchange for treating neonatal jaundice, in neonates of mothers with coagulopathy was higher than in neonates of normal mothers (31% vs. 21% and 8% vs. 21%, respectively) (p<0.001). Furthermore, the duration of hospitalization, hospitalization in NICU, and re-hospitalization during the first month of life in neonates of mothers with coagulation problems was higher than in neonates of normal mothers (p<0.001). Conclusion: Considering the high prevalence of neonatal problems in newborns of mothers with coagulation problems and their lower birth weight, further care measures should be provided for them. &nbsp
