The Resource Description Framework and the Resource Description Framework Schema Specification are supposed to be the foundations of the Semantic Web, in that all other Semantic Web languages are to be layered on top of them. It turns out that such a layering cannot be achieved in a straightforward way. This paper describes the problem with the straightforward layering and lays out several alte...

Over the years it has been an important goal to optimize the treatment of subfertility in order to obtain a better pregnancy rate and baby-take-home rate, usually combined with the goal of decreasing the rate of multiplet pregnancies. This implies optimizing the development of embryos through improved in vitro culture methods. And it also implies optimizing the methods of selection of embryos f...

Abstract Scaled experimentation is an important approach for the investigation of complex systems but centuries has been impeded by want a scaling theory that can accommodate scale effects. The present definition effect founded on violation invariance principle arising out dimensional analysis, i.e. dimensionless equations do not change with scale. However, apart from all most rudimentary syste...

applying two definitions of the union of if-events, p. grzegorzewski gave two generalizations of the inclusion-exclusion principle for if-events.in this paper we prove an inclusion-exclusion principle for if-states based on a method which can also be used to prove grzegorzewski's inclusion-exclusion principle for probabilities on if-events.finally, we give some applications of this principle by...
