A high-dimensional regression space usually causes problems in nonlinear system identification. However, if the regression data are contained in (or spread tightly around) some manifold, the dimensionality can be reduced. This paper presents a use of dimension reduction techniques to compose a two-step identification scheme suitable for high-dimensional identification problems with manifold-val...

background: human error is the most important cause of occupational and non-occupational accidents. because, it seems necessary to identify, predict and analyze human errors, and also offer appropriate control strategies to reduce errors which cause adverse consequences, the present study was carried out with the aim of identifying human errors while operating meat grinder and offer suggestions...

humans are born with potential abilities which may emerge due to certain circumstances. in educational environments, needs, interests and capacities of individuals are wide and varied. therefore, developers and educators of training programs must provide special facilities to identify talented people in the way that justice is observed for all people. meanwhile, there is no doubt that technolog...

objective: fungal nail infection (onychomycosis) is a common disease in all communities consisting about 50 percent of nail disorders. yeasts are one of the important causative agents of onychomycosis. identification of the yeast species is important in the epidemiological and therapeutical point of views. the aim of the present study is the precise species identification of the pathogenic yeas...

this study is a review on the genus helvella (pezizales, helvellaceae) in iran. study on samples deposited in iran fungal herbarium along with the fresh materials collected by the author revealed that seven species of helvella, h. acetabulum, h. atra, h. crispa, h. elastica, h. ephippium, h. lacunosa and h. leucopus (as h. monachella) have already been reported from iran. three other species vi...

background: lipophilic yeasts of the genus malassezia has been placed among the basidiomycota phylum in the family of cryptococcaceae. the genus malassezia comprises yeasts with a natural habitat of the skin of many warm-blooded vertebrates, and human, but they are also associated with several skin diseases such as tinea versicolor, seborrehoeic dermatitis and even systemic infections. the genu...

Since sturgeons have no external sexual dimorphism and there are no external markers to determine sex, internal examination of the gonads should be used to sex identification. The present study describes the biopsy method and histological observations of the gonads of great sturgeon (Huso huso) in both sexes at different age classes. Sex and maturity stages of 226 great sturgeons were identifie...

during a survey, five known species of plant-parasitic nematodes of the families tylenchidae and dolichodoridae (tylenchomorpha: tylenchoidea) were collected and identified from several locations in golestan, guilan, kurdistan, and fars provinces. paratrophurus kenanae, tylenchus elegans and t. ritae, as new records for iranian nematode fauna, with the two previously reported species filenchus ...
