The water mite subfamily Notoaturinae Besch has a typical Gondwanan distribution, with 9 genera in Australia, 3 genera in Chile, 2 genera in South Africa and one in East Africa (Cook 1986, 1988, 1998, Smit 2010). Remarkably, the genus is lacking in New Guinea and New Caledonia as both islands have a typical Australasian water mite fauna (Wiles 1997, Smit 2002, 2009, 2011, 2013). New Zealand has...

This paper addresses the potential uncertainty in Cook (2007)’s methodology to classify dual-role factors by introducing a useful property. In addition, if the assumption that dual-role factors can be clearly classified into either inputs or outputs, which underlies Cook (2007), doesn't hold, an extension of DEA model incorporating dual-role factors is proposed in this paper. Then a theorem is ...

In this work we consider the rendering equation derived from the illumination model called Cook-Torrance model. A Monte Carlo (MC) estimator for numerical treatment of the this equation, which is the Fredholm integral equation of second kind, is constructed and studied.
