The six species of Neaspasia Diakonoff present in mainland Africa are described and illustrated. Niphadophylax albonigra Razowski & Wojtusiak and N. sophrona Razowski & Wojtusiak are transferred to Conaspasia, new genus. Four new species are described: Neaspasia coronana Aarvik, new species, N. karischi Aarvik, new species, N. malamigambo Aarvik, new species, and Conaspasia congolana Aarvik, ne...

in this article I present a method to use Viola and Jones algorithm for hand gesture recognition. A training method and an algorithm to choose the most likely gesture have been suggested. Tests under low cluttered environment show good detection rate. Keywords-; Hand Gusture, Viola and Jones

We isolated and characterized 11 microsatellite loci in the Mona Island iguana (Cyclura cornuta stejnegeri). Eleven loci exhibit moderate to high allelic diversity (two to 12 alleles, mean = 4.5) and polymorphism (mean observed heterozygosity, 0.56; range, 0.26 to 0.78) in 41 adults. This marker set has low probability of identity and high parentage exclusion power and will be suitable for stud...

In this paper we present two improvements over Viola and Jones [1] training scheme for face detection. The first is 300-fold speed improvement over the training method presented by Viola and Jones [1] with a modest increase in execution time. The second is a principled method for determining a cascade classifier of optimal speed. We present some preliminary results of our methods.

to be the soloist in William Walton's Viola Concerto. Perhaps it's more a fantasy, than an ambition, as I'm not a good enough viola player to manage it. But if I were to have a go, my main experience of learning things has been in medicine. Is learning music the same? Perhaps I should start by writing some competency statements. Let's assume, that in order to start the module 'Walton's Viola Co...

Recent reports on bee health suggest that sublethal doses of pesticides have negative effects wild reproduction and ultimately their population growth. Females the solitary horned mason Osmia cornuta, evaluate thoracic vibrations odours males to assess male quality. When certain criteria are met, female accepts copulates. However, these signals were found be modified by in other hymenopterans. ...
